11.000.000 de km2 pour quoi faire? Le cas de la Nouvelle-Calédonie. Synthèse et perspectives en termes de forme et de degré de protection des milieux naturels marins
Provedor de dados: 5
Autores: Loubersac, Lionel.
This text, published in the magazine “Challenge. Le magazine du Pacifique” deals with the quite unique Caledonian case as far as its maritime character is concerned and is part of a related research programme of the French Institute for the Sea (IFM) on the issue: “11.000.000 square kilometres, what for?” To better address this question, an analysis grid sets the stage with regard to six main issues: legal status; parties involved; characteristics of natural habitats; safety and hazards; patterns of development and operational procedures; protection policies and tools. We deal below with the basic elements relative to the sixth of these points: policies and tools of the environmental protection in New Caledonia. Il reminds the history gradually established...

120,000 year record of sea ice in the North Atlantic
Provedor de dados: 5
Autores: Maffezzoli, Niccolò; Vallelonga, Paul; Edwards, Ross; Saiz-lopez, Alfonso; Turetta, Clara; Kjær, Helle Astrid; Barbante, Carlo; Vinther, Bo; Spolaor, Andrea.
Although it has been demonstrated that the speed and magnitude of recent Arctic sea ice decline is unprecedented for the past 1,450 years, few records are available to provide a paleoclimate context for Arctic sea ice extent. Here we present a 120 kyr record of bromine enrichment from the RECAP ice core, coastal East Greenland, and reconstruct past sea ice conditions in the North Atlantic as far north as the entrance of the Arctic Ocean (50–85° N). Bromine enrichment has been previously employed to reconstruct first-year sea ice (FYSI) in the Canadian Arctic over the last glacial cycle. We find that during the last deglaciation, the transition from multi-year sea ice (MYSI) to FYSI started at ∼ 17.6 kyr, synchronous with sea ice reductions observed in the...

125000 ans d'enregistrements récifaux des stagnations du niveau de la mer dans l'Océan Indien (Archipel des Glorieuses)
Provedor de dados: 5
Autores: Jorry, Stephan; Jouet, Gwenael; Le Roy, Pascal; Prat, Sophie; Camoin, Gilbert; Vella, Claude; Caline, Bruno.
Suite à l’initiation du programme REEFCORES (REEFs and CORals form the EparseS), deux missions menées en 2011 et en 2013 dans l’Archipel des Glorieuses (Nord Madagascar) ont permis de documenter les empreintes des épisodes de déglaciation dans la morphologie des terrasses récifales émergées et submergées. L’objectif principal de cette étude est d’abord de documenter les stagnations du niveau marin qui ont été engendrées au cours de la dernière remontée du niveau marin et sur les terrasses du dernier interglaciaire (MIS 5e). Cette zone située autour des Seychelles, du fait de sa stabilité (isostasie très faible), est idéalement placée pour reconstituer avec précision les variations globales du niveau marin (Milne and Mitrovica, 2008).

The Australian marine research, industry, and stakeholder community has recently undertaken an extensive collaborative process to identify the highest national priorities for wind-waves research. This was undertaken under the auspices of the Forum for Operational Oceanography Surface Waves Working Group. The main steps in the process were first, soliciting possible research questions from the community via an online survey; second, reviewing the questions at a face-to-face workshop; and third, online ranking of the research questions by individuals. This process resulted in 15 identified priorities, covering research activities and the development of infrastructure. The top five priorities are 1) enhanced and updated nearshore and coastal bathymetry; 2)...

1967-77: ten years of marine geology and geophysics
Provedor de dados: 5
Autores: Le Pichon, Xavier.
Plate tectonics gave a great stimulus to marine geology and geophysics; in the years since its enunciation there have been major drilling programmes, a new science of global palaeoenvironmental oceunography and much more detailed oceanographic surveYs. The pace shows no sign of slackening-in the next few years the passive continental margins will be muchstudied. [NOT CONTROLLED OCR]

1er reporting du projet SEA-ERA MERMAID (juin - décembre 2013)
Provedor de dados: 5
Autores: Sanna, Serena; Andral, Bruno.
Le projet SEA-ERA MERMAID « Marine Environmental targets linked to Regional Management schemes based on Indicators Developed for the Mediterranean » a été lancé le 12 juin 2013 à Athènes. Son objectif est de fournir des éléments scientifiques pour la définition du bon état écologique au sens DCSMM, en complément des projets existants (PERSEUS) pour 5 descripteurs: Populations exploitées (D3), Conditions hydrographiques (D7), Contaminants dans l’environnement et les ressources exploitées (D8, D9), Déchets (D10). L’intérêt de Mermaid réside dans le fait qu’il se focalise sur des échelles réduites à savoir trois sites pilotes : golfe du Lion, golfe de Saronikos (Ouest d’Athènes), bassin Silicien (entre côtes turques et Chypre). A ces échelles MERMAID tentera...

210Po and 210Pb trophic transfer within the phytoplankton–zooplankton–anchovy/sardine food web: a case study from the Gulf of Lion (NW Mediterranean Sea)
Provedor de dados: 5
Autores: Strady, Emilie; Harmelin-vivien, Mireille; Chiffoleau, Jean-francois; Veron, Alain; Tronczynski, Jacek; Radakovitch, Olivier.
The transfer of 210Po and 210Pb in the food web of small pelagic fishes (from phytoplankton and zooplankton to anchovy Engraulis encrasicolus and sardine Sardina pilchardus) is investigated in the Gulf of Lion (GoL). We present original data of 210Po and 210Pb activity concentrations, C and N stable isotope ratios, measured (i) from different size classes of phytoplankton and zooplankton during spring and winter in different environments of the GoL, and (ii) in two fish species. Significant spatial patterns based on 210Po, 210Pb activity concentrations and 210Po/210Pb ratios in the different plankton size classes are evidenced by hierarchical clustering, both in spring and winter. This variability, also observed for C and N stable isotopes ratios, is...

Trench-parallel thrust faults verging both landward and seaward were mapped in the portion of wedge located between northern Sumatra and the Indian-Indonesian boundary. The spatial aftershocks distribution of the 26th December 2004 earthquake shows that the post-seismic motion is partitioned along two thrust faults, the Lower and Median Thrust Faults, the latter being right-laterally offset by a N-S lower plate fracture zone located along the 93.6 degrees N meridian. Between February 2005 and August 2005, the upper plate aftershock activity shifted from southeast of this fracture zone to northwest of it, suggesting that the lower plate left-lateral motion along the fracture zone may have induced a shift of the upper plate post-seismic activity along the...

2-D and 3-D modelling of wide-angle seismic data: an example from the Voring volcanic passive margin
Provedor de dados: 5
Autores: Rouzo, Stephane; Klingelhoefer, Frauke; Jonquet Kolsto, Hélène; Karpuz, Ridvan; Kravik, Karl; Mjelde, Rolf; Murai, Yoshio; Raum, Thomas; Shimamura, Hideki; Williamson, Paul; Geli, Louis.
This study presents the modelling of 2-D and 3-D wide-angle seismic data acquired on the complex, volcanic passive margin of the Voring Plateau, off Norway. Three wide-angle seismic profiles were shot and recorded simultaneously by 21 Ocean Bottom Seismometers, yielding a comprehensive 3-D data set, in addition to the three in-line profiles. Coincident multi-channel seismic profiles are used to better constrain the modelling, but the Mesozoic and deeper structures are poorly imaged due to the presence of flood basalts and sills. Velocity modelling reveals an unexpectedly large 30 km basement high hidden below the flood basalt. When interpreted as a 2-D structure, this basement high produces a modelled gravity anomaly in disagreement with the observed...

2D and 3D seismic simulation for fault modeling: exploratory revision from the Gullfaks field
Provedor de dados: 5
Autores: Siddiqui, Numair A.; Mathew, Manoj. J.; Menier, David; Hassaan, M.
2D and 3D seismic data have emerged as a key tool in the oil and gas industry to visualize and understand subsurface morphology and boundaries. In addition to providing excellent structural images, the dense sampling of 2D and 3D survey can sometimes make it possible to map reservoir quality and the distribution of hydrocarbon with well-marked limitations. Here we use 2D and 3D seismic data to map and interpret basic structures and fault lines to construct 2D and 3D base fault models of the Gullfaks field, while avoiding common pitfalls. This work also highlights important concepts and principles that allow selection, interpretation and simulation of particular areas containing hydrocarbon traps through the comparison of different maps such as time...

Autores: Mouche, Alexis; He, W.; Husson, R.; Guitton, Gilles; Chapron, Bertrand; Li, Huimin.
Sentinel-1 A now routinely acquires data over the ocean since 2014. Data are processed by ESA through the Payload Data Ground Segment up to Level-2 for Copernicus users. Level-2 products consist of geo-located geophysical parameters related to wind, waves and ocean current. In particular, Sentinel-1A wave measurements provide 2D ocean swell spectra (2D wave energy distribution as a function of wavelength and direction) as well as integrated parameters such as significant wave height, dominant wavelength and direction for each partition. In 2016, Sentinel-1 B will be launched by ESA and GF-3 by CNSA. Then in 2018, CFOSAT (China France Oceanography Satellite project), a joint mission from the Chinese and French Space Agencies, will be launched. They will...

2D vortex interaction in a non-uniform flow
Provedor de dados: 5
Autores: Perrot, Xavier; Carton, Xavier.
In a two-dimensional incompressible fluid, we study the interaction of two like-signed Rankine vortices embedded in a steady shear/strain flow. The numerical results of vortex evolutions are compared with the analytical results for point vortices. We show the existence of vortex equilibria, and of merger for initial distances larger than those without external flow. The evolutions depend on the initial orientation of the vortices in the external flow.

Productivity of tropical lowland moist forests is often limited by availability and functional allocation of phosphorus (P) that drives competition among tree species and becomes a key factor in determining forestall community diversity. We used non-target 31P-NMR metabolic profiling to study the foliar P-metabolism of trees of a French Guiana rainforest. The objective was to test the hypotheses that P-use is species-specific, and that species diversity relates to species P-use and concentrations of P-containing compounds, including inorganic phosphates, orthophosphate monoesters and diesters, phosphonates and organic polyphosphates. We found that tree species explained the 59% of variance in 31P-NMR metabolite profiling of leaves. A principal component...

3-Acetoxy-fatty acid isoprenyl esters from androconia of the ithomiine butterfly Ithomia salapia
Provedor de dados: 5
Autores: Mann, Florian; Szczerbowski, Daiane; De Silva, Lisa; Mcclure, Melanie; Elias, Marianne; Schulz, Stefan.
Male ithomiine butterflies (Nymphalidae: Danainae) have hairpencils on the forewings (i.e. androconia) that disseminate semiochemicals during courtship. While most ithomiines are known to contain derivatives of pyrrolizidine alkaloids, dihydropyrrolizines or g-lactones in these androconia, here we report on a new class of fatty acid esters identified in two subspecies, Ithomia salapia aquinia and I. s. derasa. The major components were identified as isoprenyl (3-methyl-3-butenyl) (Z)-3-acetyloxy-11-octadecenoate, isoprenyl (Z)-3-acetyloxy-13-octadecenoate (12) and isoprenyl 3-acetyloxyoctadecanoate (11) by GC/MS- and GC/IR-analyses, microderivatizations, and synthesis of representative compounds. The absolute configuration of 12 was determined to be R. The...

We present a detailed 3-D P-wave velocity model obtained by first-arrival travel-time tomography with seismic refraction data in the segment boundary of the Sumatra subduction zone across Simeulue Island, and an image of the top of the subducted oceanic crust extracted from depth-migrated multi-channel seismic reflection profiles. We have picked P-wave first arrivals of the air-gun source seismic data recorded by local networks of ocean-bottom seismometers, and inverted the travel-times for a 3-D velocity model of the subduction zone. This velocity model shows an anomalous zone of intermediate velocities between those of oceanic crust and mantle that is associated with raised topography on the top of the oceanic crust. We interpret this feature as a...

3-D crustal density model of the Sea of Marmara
Provedor de dados: 5
Autores: Gholamrezaie, Ershad; Scheck-wenderoth, Magdalena; Bott, Judith; Heidbach, Oliver; Strecker, Manfred R.
The Sea of Marmara, in northwestern Turkey, is a transition zone where the dextral North Anatolian Fault zone (NAFZ) propagates westward from the Anatolian Plate to the Aegean Sea Plate. The area is of interest in the context of seismic hazard of Istanbul, a metropolitan area with about 15 million inhabitants. Geophysical observations indicate that the crust is heterogeneous beneath the Marmara basin, but a detailed characterization of the crustal heterogeneities is still missing. To assess if and how crustal heterogeneities are related to the NAFZ segmentation below the Sea of Marmara, we develop new crustal-scale 3-D density models which integrate geological and seismological data and that are additionally constrained by 3-D gravity modeling. For the...

3-D environmental extreme value models for the tension in a mooring line of a semi-submersible
Provedor de dados: 5
Autores: Raillard, Nicolas; Prevosto, Marc; Pineau, H.
Design optimization is crucial as offshore structures are exposed to deeper and harsher marine conditions. The structure behaviour is dependent on several joint environmental parameters (wind, wave, currents, etc.). Environmental contours are useful representations to provide multivariate design conditions. However, these contours may lead to different design points depending on the method used to compute them, and thus may be misleading to structural engineer. In this work, we propose to use a response meta-model for the inter-comparison of some state-of-the-art methods available for modelling multivariate extremes, in order to provide a straightforward methodology, focusing on the derivation of three-dimensional contours. The considered case study...

3D Modeling of the Elastic-Plastic Behavior of Thin Aeronautical Adhesive Films Suited for a Wide Range of Tensile/Compression-Shear Loads
Provedor de dados: 5
Autores: Maurice, Julien; Creac'Hcadec, Romain; Cognard, Jean-yves; Davies, Peter; Meirinhos, Georges; Mahdi, Stephane.
Adhesive bonding is an interesting structural assembling technique for weight saving in modern commercial aircraft, in which the use of composites materials is increasing. In order to meet both optimization and respect of safety conception constraints, the development of accurate numerical strategies is required. Thus, improvement in the experimental characterization and in the design of reliable numerical tools for bonded assemblies is necessary. This paper presents the characterization of the elastic-plastic behaviour of four aeronautical adhesive films, consisting of two epoxy-based resins supported by two types of carrier. The characterization over a wide range of monotonic proportional tensile-shear loads is performed using a modified Arcan test...

3D modelling in the Sado estuary using a new generic vertical discretization approach
Provedor de dados: 5
Autores: Martins, F; Leitao, P; Silva, A; Neves, R.
Sado estuary (Portugal) is a mesotidal well-mixed estuary. The flow however, displays strong three-dimensional features associated with bathymetry variations. The flow is simulated using a three-dimensional primitive equation model based on the finite-volume method and incorporating a new concept for the vertical discretization. The innovative features of the model are analysed and the advantages of the finite-volume method to implement the generic vertical discretization are put into evidence. The model was validated using water level, velocity and salinity measurements in several stations along the estuary. Results show the influence of main channel's strong curvature on the generation of secondary flows inside the estuary. The steep bathymetry of the...

3D modelling of seasonal evolution of Loire and Gironde plumes on Biscay Bay continental shelf
Provedor de dados: 5
Autores: Lazure, Pascal; Jegou, Anne-marie.
A 3D model of the Atlantic shelf has been developed and applied to study shelf dynamics and evolution of hydrology. The model takes the combined effects of tide, wind, river discharges and surface heat flux into account. Time scales vary from 1 day to several years. Following a brief description of the model and forcing variables, the behaviour of the Loire and Gironde plumes is described, first for winter and spring, then over a period of several years, under realistic forcing. The results show that plume evolution depends on the high Variability of river runoff and winds. Model simulations performed over 7 years (1990 to 1996) have highlighted several features of these plumes: 1) In early winter and periods of high river runoff, plumes usually spread...

The aim of this study is to propose a 3-dimension reconstruction method of small-scale scenes improved by a new image acquisition method for quantitative measurements. A stereovision system is used to acquire images in order to obtain several shots of an object, at regular intervals according to a predefined trajectory. A complete methodology of 3D reconstruction is exposed to perform a dense 3D model with texture mapping. A first result on natural images collected with the stereovision system during sea trials has been obtained.

Autores: Bayrakci, Gaye; Laigle, Mireille; Becel, A.; Hirn, A.; Taymaz, T.; Yolsal-cevikbilen, S.
A 3-D tomographic inversion of first arrival times of shot profiles recorded by a dense 2-D OBS network provides an unprecedented constraint on the P-wave velocities heterogeneity of the upper-crustal part of the North Marmara Trough (NMT), over a region of 180 km long by 50 km wide. One of the specific aims of this controlled source tomography is to provide a 3-D initial model for the local earthquake tomography (LET). Hence, in an original way, the controlled source inversion has been performed by using a code dedicated to LET. After several tests to check the results trade-off with the inversion parameters, we build up a 3-D a priori velocity model, in which the sea-bottom topography, the acoustic and the crystalline basements and the Moho interfaces...

The probable N055°-oriented extinct spreading ridge of the East Sub-basin is cut across by the post-spreading volcanic ridge oriented approximately E–W in its western part and called the Zhenbei–Huangyan seamounts chain. A three-dimensional ocean bottom seismometer survey was conducted in 2011 and covered both the extinct spreading ridge and the Zhenbei–Huangyan seamounts chain in the East Sub-basin. The comprehensive seismic record sections of 39 ocean bottom seismometers underline the high-quality data with clear and reliable P-wave seismic first arrivals. The three-dimensional tomographic results show that the crust is oceanic on each side of the Zhenbei–Huangyan seamounts chain. The seafloor spreading lineaments and associated fracture zones pattern...

3-D slope stability analysis: A probability approach applied to the nice slope (SE France)
Provedor de dados: 5
Autores: Leynaud, Didier; Sultan, Nabil.
Recent geophysical and geotechnical data acquired on the Nice shelf to the east of the 1979 landslide source area, Suggest slow deformations processes which could lead to future catastrophic slope failure. According to these preliminary interpretations, it is of major interest to perform a slope stability evaluation to define the hazard and quantify the danger related to a probable instability on this slope. A probabilistic approach is proposed here using a modified version of the SAMU_3D model, a 3-D slope stability software recently developed by Sultan and others to account for complex geometry. The 3-D analysis is based on the upper bound theorem of plasticity developed by Chen and others. One of the main features of the original model is to allow...

The development of 3D printing in recent years opens up a vast array of possibilities in the field of flow analysis. In the present study, a new 3D-printed flow system has been developed for the selective spectrophotometric determination of lead in natural waters. This system was composed of three 3D-printed units (sample treatment, mixing coil and detection) that might have been assembled without any tubing to form a complete flow system. Lead was determined in a two-step procedure. A preconcentration of lead was first carried out on TrisKem Pb Resin located in a 3D-printed column reservoir closed by a tapped screw. This resin showed a high extraction selectivity for lead over many tested potential interfering metals. In a second step, lead was eluted by...

In recent years, the development of 3D printing in flow analysis has allowed the creation of new systems with various applications. Up to now, 3D printing was mainly used for the manufacture of small units such as flow detection cells, preconcentration units or mixing systems. In the present study, a new 3D printed lab-on-valve system was developed to selectively quantify lead and cadmium in water. Different technologies were compared for lab-on-valve 3D printing. Printed test units have shown that stereolithography or digital light processing are satisfactory techniques for creating complex lab-on-valve units. The lab-on-valve system was composed of two columns, eight peripheral ports and a central port, and a coil integrating baffles to increase mixing...

40 AR/39 AR ages for the alkaline volcanism and the basement of Gorringe Bank, North atlantic Ocean
Provedor de dados: 5
Autores: Feraud, Gilbert; Gastaud, Janine; Auzende, Jean-marie; Olivet, Jean-louis; Cornen, Guy.
Gorringe Bank is situated on the Europe-Africa plate boundary at the eastern end of the Azores-Gibraltar fracture zone. It has two summits. Gettysburg Bank to the southwest and Ormonde Bank to the northeast. We applied the 40Ar/39AR stepwise heating method to date six samples of the alkaline volcanic rocks. Two gabbros from the Ormonde Bank and a dolerite from the Gettysburg Bank. The results suggest that the alkaline volcanism lasted probably for less than 6 Ma(66-60 Ma). Although the nature of this volcanism precludes any subduction feature during its setting. the alkaline volcanism of Ormonde is probably linked to Upper Cretaceous/Eocene compressive tectonic events.  The basement rocks of Gorringe Bank reveal disturbed 40Ar/39Ar age spectra.  One...

Autores: ICES.
Implementation of ecosystem-based approaches to marine management points to several shared objectives between conservation and fishery management that require better knowledge of the life history of the exploited resources, elucidation of the information encoded in the calcified tissues (otoliths, scales, bones, shells, and corals) of marine and freshwater organisms, and support for knowledge-based, sustainable ocean management and use.  Calcified tissues have been employed since the 19th century to gain knowledge of life traits, population structure, and environmental relationships of fish and molluscs.  Breakthrough advances include the discovery by Pannella (1971) of the daily growth increments and the discovery by Radtke (1984) of otolith tracer...

80’s population-specific compositions of two related anadromous shad species during the oceanic phase determined by microchemistry of archived otoliths

Autores: Nachón, David José; Bareille, Gilles; Drouineau, Hilaire; Tabouret, Helene; Taverny, Catherine; Boisneau, Catherine; Berail, Sylvain; Pécheyran, Christophe; Claverie, Fanny; Daverat, Françoise.
The specific stock composition and dispersion of anadromous fish species aggregations in the marine environment are poorly known, while they can play a major role in the metapopulation dynamics. Otolith microchemistry has proven to be a powerful tool to address natal origins of anadromous fish. We used archived otolith microchemistry to investigate the population-specific composition of European shads (Alosa alosa and Alosa fallax) subadults in the ocean during the 80’s. The allocation of natal origin was addressed relying on contemporary water and juveniles signatures within a Bayesian model. A great discrimination of natal origin was obtained at the Biscay Gulf scale. However, the discrimination of 80’s natal origin for the southern rivers with similar...

A 0.55-Ma paleotemperature record from the Subantarctic zone: Implications for Antarctic Circumpolar Current development
Provedor de dados: 5
Autores: Becquey, S; Gersonde, R.
Estimates of summer sea surface temperatures (SSSTs) derived from planktic foraminiferal associations using the Modern Analog Technique and combined with isotopic analyses and determination of ice-rafted debris, mirror the Pleistocene evolution of the planktic Subantarctic surface waters in the Atlantic Ocean. The SSSTs indicate that the isotherms that define the modern polar front zone and Subantarctic front, were located at more northerly latitudes (up to 7degrees) during most of the investigated period, which covers the past 550 kyr. Exceptions are during climatic optima in the early Holocene, at marine isotope stages (MIS) 5.5, 7.1, 7.5, 9.3, and presumably during MIS 11.3 when SSSTs exceeded modern values by 1degrees-5degreesC. The close similarity...

A 0.6 million year record of millennial-scale climate variability in the tropics
Provedor de dados: 5
Autores: Gibson, Kelly Ann; Peterson, Larry C.
A ~600 kyr long scanning X-ray fluorescence record of redox variability from the Cariaco Basin, Venezuela, provides insight into rapid climate change in the tropics over the past five glacial-interglacial cycles. Variations in the sediment accumulation of the redox-sensitive element molybdenum (Mo) can be linked to changes in Intertropical Convergence Zone migration and reveal that millennial-scale variability is a persistent feature of tropical climate over the past 600 kyr, including during periods of interglacial warmth. This new record supports the idea that high-frequency tropical climate variability is not controlled solely by ice volume changes, with implications for the role of high-latitude forcing of Intertropical Convergence Zone position and...

A 1.2 Ma record of glaciation and fluvial discharge from the West European Atlantic margin

The correlation of continental sedimentary records with the marine isotope stratigraphy is a challenge of central importance in Quaternary stratigraphy, particularly in Western Europe where long records of glaciation on land areas are particularly rare. Here we demonstrate for the first time the interrelationship of events during the last 1.2 Ma in an ocean-sediment core from the Bay of Biscay (NE Atlantic), SW of the Channel. The identification of discharge variations from tributary river systems to the 'Fleuve Manche' palaeoriver during glacio-eustatic sea-level lowstands demonstrates the correlation of the marine sediment stratigraphy to the expansion and recession of the European ice-sheets. The amplitude and chronology of European ice-sheet...

Sortable silt particle-size data and stable isotope analyses from the Corsica Trough, western Mediterranean Sea, provide a continuous palaeoceanographic record of the inflow, ventilation and vertical fluctuations of the Levantine Intermediate Water (LIW) in the northern Tyrrhenian Sea for the last 130,000 years. The results presented herein reveal that climate changes drive the Mediterranean intermediate circulation on Milankovitch to millennial time-scales. Intensified intermediate inflow and ventilation in the Corsica Trough occurred throughout the last glacial interval, with a cold / faster – warm / slower pattern existing between the Dansgaard-Oeschger climatic oscillations (including Heinrich events) and the LIW variability. By contrast, a weak...

A 2.14-Myr astronomically tuned record of relative geomagnetic paleointensity from the western Philippine Sea
Provedor de dados: 5
Autores: Horng, Cs; Roberts, Ap; Liang, Wt.
We present a 2.14-Myr astronomically tuned relative geomagnetic paleointensity record from the western Philippine Sea. Pseudosingle-domain titanomagnetite is the only magnetic mineral identified and variations in titanomagnetite concentration fall well within the accepted limits for relative paleointensity variations. No significant temporally persistent periodicities are observed in wavelet analyses of the paleointensity time series or in the rock magnetic parameters used for relative paleointensity normalization. This suggests that our paleointensity record is largely free of rock magnetic or lithological artefacts and that it represents a reliable record of geomagnetic behavior with no evidence for modulation of the field at Earth orbital periods. The...

A 27 kyr terrestrial biomarker record in the southern Indian Ocean
Provedor de dados: 5
Autores: Sicre, Marie-alexandrine; Labeyrie, Laurent; Ezat, Ullah; Mazaud, Alain; Turon, Jean-louis.
Terrestrial inputs were reconstructed using high molecular weight n-alkane concentrations recorded in the sub-Antarctic Indian Ocean core MD94-103 (45 degrees 35'S, 86 degrees 31'E, 3560 m) to examine regional changes in the atmospheric circulation over the last 27 kyr. This record was compared to the dust content of EPICA-Dome C ice and continental data from South Africa ( e. g., pollen sequences and isotope records in speleothems) to get a comprehensive understanding of atmospheric links between low and midlatitudes of the Indian Ocean. Terrestrial n-alkanes indicate higher glacial than Holocene inputs and marked glacial oscillations. Minimum values during the Last Glacial Maximum (LGM) are consistent with colder and drier climate and presumably caused...

A 2700-year record of ENSO and PDO variability from the Californian margin based on coccolithophore assemblages and calcification
Provedor de dados: 5
Autores: Beaufort, Luc; Grelaud, Michael.
The El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) account for a large part of modern climate variability. Over the last decades, understanding of these modes of climate variability has increased but prediction in the context of global warming has proven difficult because of the lack of pertinent and reproducible paleodata. Here, we infer the dynamics of these oscillations from fossil assemblage and calcification state of coccolithophore in the Californian margin because El Niño has a strong impact on phytoplankton ecology and PDO on the upwelling intensity and hence on the ocean chemistry. Intense Californian upwelling brings water rich in CO2 and poor in carbonate ions and coccolithophores secrete lower calcified...

Seawater samples collected in the northeast Pacific from 112 degrees 50'W to 126 degrees 36'W along a latitudinal band (21-25 degrees N) have been analysed for Ra-228 and Ra-226. Both nuclides exhibit their characteristic distributions. In the surface water, the exponential-like decrease of Ra-228 away from Baja California can be interpreted by horizontal water mixing with eddy diffusion coefficients (K-x) of 1 x 10(6) cm(2) s(-1) and 5 x 10(7) cm(2) s(-1) for scale lengths of 200 km and 1000 km, respectively. In the bottom waters, the decrease of Ra-228 away from bottom sediments can be modeled by vertical eddy diffusivities (K-z) of 15-30 cm(2) s(-1) except at one station (24 degrees 16.9' N, 115 degrees 8.9' W) where a value of 120 cm(2) s(-1) is...

A 37 years hindcast of a coupled physical-biogeochemical model and its use for fisheries oceanography in the Bay of Biscay
Provedor de dados: 5
Autores: Huret, Martin; Petitgas, Pierre; Struski, Caroline; Leger, Fabien; Sourisseau, Marc; Lazure, Pascal.
Overexploitation and climate change are increasingly causing unanticipated changes in marine ecosystems, such as higher variability in fish recruitment and shifts in species distribution, pressing for developing fisheries oceanography. In the meantime, operational oceanography rapidly progresses and its products become easy to access to a large community, among them fisheries scientists. Multiyear oceanographic reanalyses (hindcasts) were identified has a priority product by the ICES WG on Operational Oceanographic Products for Fisheries and Environment (WGOOFE). We performed a 37 years hindcast (1972-2008) run with a coupled physical-biogeochemical model (ECO-MARS3D) over the Bay of Biscay, using realistic meteorological and run-off forcing. We first...

Autores: Huret, Martin; Petitgas, Pierre; Sourisseau, Marc; Struski, Caroline; Leger, Fabien; Lazure, Pascal.
Operational oceanography rapidly progresses and its products become easy to access to a large community, among them fisheries scientists. The products cover both near real-time environment information (on scales of days to weeks) but also retrospective analysis providing long time series of environment parameters. Here we describe a 38 years hindcast of a coupled physical-biogeochemical model of the Bay of Biscay as well as the indices and major information that were derived from it.

A 3D study of the bubble sweep-down phenomenon around a 1/30 scale ship model
Provedor de dados: 5
Autores: Mallat, Bachar; Germain, Gregory; Billard, Jean-yves; Gaurier, Benoit.
The bubble sweep-down phenomenon around oceanographic research vessels generates acoustic disturbances. A specific experimental protocol in a wave and current circulating tank is used to study this phenomenon around a 1/30 scale ship model in a configuration with current, waves and ship motions. 3D visualizations of the bubble clouds and Stereo-PIV (Particle Image Velocimetry) measurements results, both obtained in the bow vicinity of the ship model, are presented in this paper. The behaviour of the breaking wave with bubble generation is studied and the spatial evolution of the bubble clouds is investigated. It is demonstrated that the bubble cloud generation is mainly conditioned by the ascending vertical velocity of the flow near the bow. It is observed...

A 4D-variational approach applied to an eddy-permitting North Atlantic configuration: Synthetic and real data assimilation of altimeter observations
Provedor de dados: 5
Autores: Ferron, Bruno.
The increasing number of oceanic observations calls for the use of synthetic methods to provide consistent analyses of the oceanic variability that will support a better understanding of the underlying mechanisms. In this study, a 1/3 degrees eddy-permitting model of the North Atlantic (from 20 degrees S to 70 degrees N) is combined with a 4D-variational method to estimate the oceanic state from altimeter observations. This resolution allows a better extraction of the physical content of altimeter data since the model spatial scales are more consistent with the data than coarser assimilation exercises because of a lower error in model representativity. Several strategies for the assimilation window are tested through twin experiments carried out under the...

Borehole PRGL1-4 drilled in the upper slope of the Gulf of Lion provides an exceptional record to investigate the impact of late Pleistocene orbitally-driven glacio-eustatic sea-level oscillations on the sedimentary outbuilding of a river fed continental margin. High-resolution grain-size and geochemical records supported by oxygen isotope chronostratigraphy allow reinterpreting the last 500 ka upper slope seismostratigraphy of the Gulf of Lion. Five main sequences, stacked during the sea-level lowering phases of the last five glacial-interglacial 100-kyr cycles, form the upper stratigraphic outbuilding of the continental margin. The high sensitivity of the grain-size record down the borehole to sea-level oscillations can be explained by the great width of...

New proxy records from deep‐sea sediment cores from the northwestern continental margin of Western Australian reveal a 5.3 million‐year (Ma) history of aridity and tropical‐monsoon activity in northwestern Australia. Following the warm and dry early Pliocene (~5.3 Ma), the northwestern Australian continent experienced a gradual increase in humidity peaking at about 3.8 Ma with higher than present‐day rainfall. Between 3.8 and about 2.8 Ma, climate became progressively more arid with more rainfall variability. Coinciding with the onset of the northern hemisphere glaciations and the intensification of the northern hemisphere monsoon, aridity continued to increase overall from 2.8 Ma until today, with greater variance in precipitation and an increased...

A 6 year record of baroclinic transport variability of the Antarctic Circumpolar Current at 140 degrees E derived from expendable bathythermograph and altimeter measurements
Provedor de dados: 5
Autores: Rintoul, Sr; Sokolov, S; Church, J.
Repeat hydrographic sections across the Antarctic Circumpolar Current are used to derive an empirical relationship between upper ocean temperature and the baroclinic transport stream function. Cross validation shows this relationship can be used to infer baroclinic transport (above and relative to 2500 dbar) from temperature measurements with an error of a few per cent. The mean transport distribution derived from 31 austral summer expendable bathythermograph (XBT) sections over a 6 year period consists of westward flow immediately south of Tasmania, a broad band of strong eastward flow between 50degrees and 55degreesS, and three cores of eastward flow south of 55degreesS. By defining a second empirical relationship between surface dynamic height and...

The Greenland Ice Core Chronology 2005 (GICC05) is a time scale based on annual layer counting of high-resolution records from Greenland ice cores. Whereas the Holocene part of the time scale is based on various records from the DYE-3, the GRIP, and the NorthGRIP ice cores, the glacial part is solely based on NorthGRIP records. Here we present an 18 ka extension of the time scale such that GICC05 continuously covers the past 60 ka. The new section of the time scale places the onset of Greenland Interstadial 12 (GI-12) at 46.9 +/- 1.0 ka b2k (before year AD 2000), the North Atlantic Ash Zone II layer in GI-15 at 55.4 +/- 1.2 ka b2k, and the onset of GI-17 at 59.4 +/- 1.3 ka b2k.

A Bayesian framework to objectively combine metrics when developing stressor specific multimetric indicator
Provedor de dados: 5
Autores: Drouineau, Hilaire; Lobry, Jeremy; Delpech, C.; Bouchoucha, Marc; Mahevas, Stephanie; Courrat, A.; Pasquaud, S.; Lepage, M.
In the context of the European Water Framework Directive (WFD), monitoring programs and related indicators have been developed to assess anthropogenic impacts on various components of aquatic ecosystems. While great precautions are usually taken when selecting and calculating relevant core metrics, little attention is generally paid to the generation of the multimetric indicator, i.e. the combination of the different core metrics. Indeed, most multimetric indicators are generated by simply averaging or summing metrics, without taking into account their sensitivity and their variability. Moreover, few indicators provide a rigorous estimate of the uncertainty of the assessments, while this estimation is essential for managers. In this context, we developed a...

A Bayesian state-space model to estimate population biomass with catch and limited survey data: application to the thornback ray (Raja clavata) in the Bay of Biscay
Provedor de dados: 5
Autores: Marandel, Florianne; Lorance, Pascal; Trenkel, Verena M.
The thornback ray (Raja clavata) in the Bay of Biscay is presumed to have declined during the 20th Century. To evaluate this decline and estimate biomass trajectories, a hypothetical catch time series was created for the period 1903-2013. A Bayesian state-space biomass production model with a Schaefer production function was fitted to the hypothetical catch time series and to a shorter research vessel Catch Per Unit Eeffort (CPUE) time series (1973-2013, with missing years). A censored likelihood made it possible to obtain biomass estimates without a CPUE time series or only with an estimate of biomass depletion. A simulation-estimation approach showed a high sensitivity of results to the prior for the intrinsic growth rate. The model provided biomass...

A Bayesian two-stage biomass model applied to the English Channel stock of cuttlefish (Sepia officinalis)
Provedor de dados: 5
Autores: Alemany, Juliette; Rivot, Etienne; Foucher, Eric; Vigneau, Joel; Robin, Jean-paul.
Among the English Channel fishery, the importance of cuttlefish stock has increased, following the cephalopods global landings and market trend. An adapted stock assessment model is needed in order to give good management advice with accurate uncertainties. Age based methods in this species are hampered by time consuming age determination with statoliths. A model requiring few data and adapted to the species life-history is therefore proposed. An assessment of this stock was conducted in June 2015 by fitting a two-stage biomass model on a 22 years’ time-series (1992-2014). The use of a Bayesian framework is particularly adapted for decision making, allowing the propagation of uncertainty in the model. It also permits the use of different sources of...

A Bayesian two-stage biomass model for stock assessment of data-limited species: An application to cuttlefish ( Sepia officinalis ) in the English Channel
Provedor de dados: 5
Autores: Alemany, Juliette; Rivot, Etienne; Foucher, Eric; Vigneau, Joel; Robin, Jean-paul.
Cuttlefish is a key commercial species in the English Channel fishery in terms of landings and value. Age-based assessment methods are limited by time-consuming age determination with statoliths and the lack of stock assessment models tailored to this data-limited species. A two-stage biomass model is developed in the Bayesian state-space modelling framework that allows inferences to be made on the stock biomass at the start, middle and end of each fishing seasons between 1992 and 2014, while accounting for both process and measurement errors and to assimilate various sources of information. A method that uses ancillary length-frequency data is developed to provide an informative prior distribution for the biomass growth rate parameter g (E = 0.89) and its...

A behavioural fish movement approach within an anchovy IBM model to study fish migration patterns in the Bay of Biscay
Provedor de dados: 5
Autores: Politikos, Dimitrios; Huret, Martin; Petitgas, Pierre.
Modelling of fish movement behaviour within a heterogeneous marine environment is a challenging but also key issue for understanding the effect of environmental factors and climatic change on fish processes (growth, distribution, mortality, reproduction). Fish movement models have the capability to encompass the combined effect of environment and empirical knowledge of fish individuals as energy requirements, known preys and predators, swimming capacities into a unified framework. Following an Individual Based Model (IBM) approach, a fish movement model has been developed to simulate the active movement of adult anchovy in the Bay of Biscay (BoB) in response to the spatio-temporal variations of both biotic and abiotic factors, as well as its internal...

A benthic Si mass balance on the Congo margin: Origin of the 4000 m DSi anomaly and implications for the transfer of Si from land to ocean
Provedor de dados: 5
Autores: Ragueneau, O.; Regaudie-de-gioux, A.; Moriceau, B.; Gallinari, M.; Vangriesheim, Annick; Baurand, F.; Khripounoff, Alexis.
To elucidate the origin of the silicic acid (DSi) anomaly observed along the 4000 isobath on the Congo margin, we have established a benthic Si mass balance and performed direct measurements of biogenic silica (bSiO(2)) dissolution in the deep waters and in the sediments. Results strongly suggest that the anomaly originates from the sediments; the intensity of DSi recycling is consistent with the degradation of organic matter, as observed from Si:O-2 ratios in the benthic fluxes compared to that ratio observed in the anomalies. Strong imbalances, observed in both the Si and C mass balances, suggest that the biogenic matter that degrades and dissolves in these sediments near 4000 m does not come from pelagic sedimentation. It is probably not coming also...

The Biogeochemical-Argo program (BGC-Argo) is a new profiling-float-based, ocean wide, and distributed ocean monitoring program which is tightly linked to, and has benefited significantly from, the Argo program. The community has recommended for BGC-Argo to measure six additional properties in addition to pressure, temperature and salinity measured by Argo, to include oxygen, pH, nitrate, downwelling light, chlorophyll fluorescence and the optical backscattering coefficient. The purpose of this addition is to enable the monitoring of ocean biogeochemistry and health, and in particular, monitor major processes such as ocean deoxygenation, acidification and warming and their effect on phytoplankton, the main source of energy of marine ecosystems.

A bimodal alkalic shield volcano on Skiff Bank: Its place in the evolution of the Kerguelen Plateau
Provedor de dados: 5
Autores: Kieffer, B; Arndt, Nt; Weis, D.
A bimodal volcanic sequence of 230 m thickness on Skiff Bank, a western salient of the northern Kerguelen Plateau, was drilled during ODP Leg 183. The sequence comprises three main units: a mafic unit of trachybasalt flows sandwiched between two units of trachytic or rhyolitic flows and volcaniclastic rocks. Although interpretation is complicated by moderate to strong alteration of the rocks, their original chemical character can be established using the least mobile major and trace elements (Al, Th, high field strength elements and rare earth elements). High concentrations of alkalis and incompatible trace elements indicate that both mafic and felsic rocks are alkalic. The felsic rocks may have been derived by partial melting of mafic rocks, followed by...

A bio-economic analysis of experimental selective devices in the Norway lobster (Nephrops norvegicus) fishery in the Bay of Biscay

Several fleets with various fishing strategies operate as a mixed fishery in the Bay of Biscay. Among the main fleets, bottom trawlers target Norway lobster (Nephrops norvegicus) and, together with gillnetters, they also catch hake (Merluccius merluccius). Trawling leads to average-size catches that are below the minimum landing size (MLS); such catches are discarded since they cannot be sold. These discards result in negative impacts on stock renewal, as most of them do not survive. This also results in an economic loss for both bottom trawlers and gillnetters since these discards represent a future loss of rent. This study, based on the 2009 and 2010 selectivity experiments at sea, assesses the short- and long-term bio-economic impacts of four...

Autores: Steinmetz, Fabien; Thebaud, Olivier; Blanchard, Fabian; Le Floc H, Pascal; Bihel, J.
Selective fishing pressure on more highly valued marine living resources is one of the key factors proposed to explain changes occurring in fish communities and associated landings of commercial fisheries. The aim of this paper is to establish the nature of changes in the landings of French fishing fleets operating in the Bay of Biscay in the period 1973-2002, and whether these changes could be related to the relative economic attractiveness of different fish species. The analysis focuses on trends observed in the landings of all commercial fish species over the last three decades. It is based on data of annual quantities landed and ex-vessel prices compiled from official French landings records, and on bio-geographical descriptors of these species derived...

Autores: Guyader, Olivier; Daures, Fabienne; Fifas, Spyros.
The objective of this paper is to assess the benefits and costs of decommissioning policies aimed at reducing fleet capacity through premiums offered by the public authority to fishermen to scrap their vessels. A case study, the limited entry scallop fishery of the Saint Brieuc Bay, France, is used to con- sider the problem of excess capacity and to model the bioeconomic consequences of disinvestment behavior. Special attention is paid to the assessment of fishermen's willingness to leave the fishery and to the implementation of public policy in terms of budget level and premiums offered to the fishermen. Spreadsheet simulations show that the impact of decommissioning programs is positive in terms of net surplus, even in the case of increasing technical...

Autores: Guillen Garcia, Jordi; Maynou, Francesc; Floros, Christos; Sampson, David; Conides, Alexis; Kapiris, Kostas.
It has recently been shown that two deep-water red shrimp species (Aristeus antennatus and Aristaeomorpha foliacea) have the potential to support a viable fishery in the Greek Ionian Sea (eastern Mediterranean). In this article, we investigate (i) the evolution that this newly developed trawl shrimp fishery may undergo when subjected to different management measures, and (ii) the most suitable extraction rates considering the uncertainties about the resource. We further analyse the effects that potential future fuel price increases and changes in the market may have on the fishery. Forecasting the biological and economic consequences of management actions, as well as the effects of market changes on inputs and outputs before they are applied, may help...

Autores: Cisse, Abdoul; Gourguet, Sophie; Doyen, L.; Blanchard, Fabian; Pereau, J. -c.
This paper offers a theoritical and empirical model of ecosystem-based fishery management. A multi-species and multi-fleet integrating Lotka-Volterra trophic dynamics as well as production and profit assessments is developed and applied to the coastal fishery of French Guiana. This small-scale fishery constitutes a challenging example with high fish biodiversity, several non-selective fleets and a potentially increasing local food demand due to demographic growth. The dynamic model is calibrated with 13 species and four fleets using monthly catch and effort data from 2006 to 2009. Several contrasted fishing scenarios including status quo, total closure, economic and viable strategies are then simulated. They are compared from the viewpoints of both...

A biogeochemical comparison of sea loch sediments. Manganese and iron contents, sulphate reduction and oxygen uptake rates
Provedor de dados: 5
Autores: Overnell, J; Harvey, Sm; Parkes, Rj.
The sediments of the upper basins of Lochs Goil, Fyne and Etive were high in both solid phase extractable manganese (up to 3.7% w/w), and high in pore water manganese (up to 600 mu M), while Loch Linnhe sediments were low in manganese. Solid phase manganese from the surface sediments at the deepest stations was highest in those lochs where the mean residence time of the bottom water is longest, indicating the importance of manganese cycling through the water column. Porewater iron concentrations in the top 2 cm of sediment were highest near the heads of the lochs, i.e. near the main freshwater inputs. Within sediments of Lochs Goil, Fyne and Etive high rates of total sulphate reduction were associated with high relative rates of formation of acid volatile...

A biology laboratory on the seafloor
Provedor de dados: 5
Autores: Le Bris, Nadine.
Although occupied submersibles have played an essential role in the discovery and study of hydrothermal ecosystems at depths ranging from 1500–3500 m, operational constraints at great depths have meant that the wide chemical and thermal diversity of the hydrothermal environments have long remained poorly defi ned. In the last decade, use of remotely operated vehicles (ROVs) to substantially extend dive time and development of a new set of dedicated instruments have greatly expanded our capacity to characterize seafl oor hydrothermal habitats at the interface between hydrothermal fl uid and seawater. In particular, major breakthroughs in the fi eld of in situ chemical sensing and highpressure experimentation have led to a much better understanding of the...

A biomolecular proportional integral controller based on feedback regulations of protein level and activity
Provedor de dados: 5
Autores: Mairet, Francis.
Homeostasis is the capacity of living organisms to keep internal conditions regulated at a constant level, despite environmental fluctuations. Integral feedback control is known to play a key role in this behaviour. Here, I show that a feedback system involving transcriptional and post-translational regulations of the same executor protein acts as a proportional integral (PI) controller, leading to enhanced transient performances in comparison with a classical integral loop. Such a biomolecular controller-which I call a level and activity-PI controller (LA-PI)-is involved in the regulation of ammonium uptake by Escherichia coli through the transporter AmtB. The P-II molecules, which reflect the nitrogen status of the cell, inhibit both the production of...

A biophysical model of S. aurita early life history in the northern Gulf of Guinea
Provedor de dados: 5
Autores: Kone, Vamara; Lett, Christophe; Penven, Pierrick; Bourles, Bernard; Djakoure, Sandrine.
S. aurita is the most abundant small pelagic fish in the northern Gulf of Guinea. Its reproduction and recruitment depend crucially on environmental conditions. We developed a biophysical model of S. aurita early life history by coupling offline an individual-based model with the regional oceanic modeling system (ROMS). We used this model to investigate the main factors driving variability in eggs and larval dispersal and survival in the northern Gulf of Guinea. Precisely, individuals were released from different spawning areas along the coast and tracked for a period of 28 days corresponding to their planktonic phase. Individuals that remained in the coastal recruitment areas at an age more than 7 days, at which they can supposedly actively retain...

A Biosensor for Detection of DNA Sequences Based on a 50MHz QCM electronic oscillator circuit
Provedor de dados: 5
Autores: Bustabad, E. A.; Garcia, G; Rodriguez-pardo, L.; Farina, J.; Perrot, H.; Gabrielli, C.; Bucur, B.; Lazerges, M.; Rose, D.; Compere, Chantal; Arnau, A.
This work deals with the development of a high sensibility DNA biosensor based on a 50MHz Quartz Crystal Microbalance (QCM) Oscillator Electronic Circuit. The designed QCM oscillator sensor is able to detect the presence of complementary DNAs in a solution that match the sequence on a given strand in function of the changes in the output frequency of the oscillator. The design is adapted so that the Barkhausen condition is satisfied even when the quartz is immerged in liquid media. Also a comparative study of the developed 50MHz biosensor in front of a QCM oscillator with smaller frequency is carried out, with object of checking if the sensibility of the oscillator increases, allowing to detect smaller concentrations of the complementary DNA.

The ocean plays a crucial role in the functioning of the Earth System and in the provision of vital goods and services. The United Nations (UN) declared 2021–2030 as the UN Decade of Ocean Science for Sustainable Development. The Roadmap for the Ocean Decade aims to achieve six critical societal outcomes (SOs) by 2030, through the pursuit of four objectives (Os). It specifically recognizes the scarcity of biological data for deep-sea biomes, and challenges the global scientific community to conduct research to advance understanding of deep-sea ecosystems to inform sustainable management. In this paper, we map four key scientific questions identified by the academic community to the Ocean Decade SOs: (i) What is the diversity of life in the deep ocean? (ii)...

A bootstrap method for estimating bias and variance in statistical fisheries modelling frameworks using highly disparate datasets
Provedor de dados: 5
Autores: Elvarsson, B. P.; Taylor, L.; Trenkel, Verena; Kupca, V.; Stefansson, G.
Statistical models of marine ecosystems use a variety of data sources to estimate parameters using composite or weighted likelihood functions with associated weighting issues and questions on how to obtain variance estimates. Regardless of the method used to obtain point estimates, a method is required for variance estimation. A bootstrap technique is introduced for the evaluation of uncertainty in such models, taking into account inherent spatial and temporal correlations in the datasets, which are commonly transferred as assumptions from a likelihood estimation procedure into Hessian-based variance estimation procedures. The technique is demonstrated on a real dataset and the effects of the number of bootstrap samples on estimation bias and variance...

The decrease of microbial and nutrient inputs from the watershed has long dominated lagoon ecosystem management objectives. Phytoplankton biomass and abundance have drastically decreased for more than a decade and Zostera meadow have gradually recovered, expressing lagoon ecosystem restoration such as Thau lagoon. Do the progressive achievement of the good ecological status of the Thau lagoon possibly threatens the shellfish industry in terms of production and oyster quality, by reducing the carrying capacity? To provide answers about the right balance to be achieved between conservation and exploitation, a new numerical tool was developed to help in decision-making. We hereby propose to incorporate a Dynamic Energy Budget type shellfish production model...

A brief history of climate - the northern seas from the Last Glacial Maximum to global warming

The understanding of climate and climate change is fundamentally concerned with two things: a well-defined and sufficiently complete climate record to be explained, for example of observed temperature, and a relevant mechanistic framework for making closed and consistent inferences concerning cause-and-effect. This is the case for understanding observed climate, as it is the case for historical climate as reconstructed from proxy data and future climate as projected by models. The present study offers a holistic description of northern maritime climate from the Last Glacial Maximum through to the projected global warming of the 21st century in this context. It includes the compilation of the most complete temperature record for Norway and the Norwegian Sea...

A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

A call for refining the role of humic-like substances in the oceanic iron cycle

Autores: Whitby, Hannah; Planquette, Helene; Cassar, Nicolas; Bucciarelli, Eva; Osburn, Christopher L.; Janssen, David J.; Cullen, Jay T.; González, Aridane G.; Völker, Christoph; Sarthou, Geraldine.
Primary production by phytoplankton represents a major pathway whereby atmospheric CO2 is sequestered in the ocean, but this requires iron, which is in scarce supply. As over 99% of iron is complexed to organic ligands, which increase iron solubility and microbial availability, understanding the processes governing ligand dynamics is of fundamental importance. Ligands within humic-like substances have long been considered important for iron complexation, but their role has never been explained in an oceanographically consistent manner. Here we show iron co-varying with electroactive humic substances at multiple open ocean sites, with the ratio of iron to humics increasing with depth. Our results agree with humic ligands composing a large fraction of the...

We report a botulism outbreak in Charolais cattle fed with wheat flour contaminated by Clostridium botulinum type C and the management of the outbreak at each step from the clinical suspicion to the cleaning and disinfection operations. Diagnosis was based on typical suggestive clinical signs and detection of C. botulinum type C using real-time PCR in samples collected from three young affected bulls. All young exposed bulls and cows (18 animals) eventually died, but three young bulls and one cow were recovering when it was decided to euthanize them. C. botulinum type C was detected in the liver of these four animals. Analysis of the ration components demonstrated that wheat flour, wheat, and the mill used to make flour were positive for C. botulinum type...

A Case Study of Technological Switching and Technological Lock-In in the French Fisheries Sector: Why is Sustainable Change so Difficult?
Provedor de dados: 5
Autores: Le Floc'H, Pascal; Daures, Fabienne; Guyader, Olivier; Wilson, James.
Many sectors such as the fishery show classic examples of technological lock-in and path dependence, even though some economists might predict smooth switching toward technologies that are more cost effective and sustainable. We use ideas from the evolutionary economics and public choice literatures to explain why trajectories of technological change, especially in fisheries, may not be smooth at all, but rather punctuated. The interest of technological change and switching behavior for fisheries economists and managers stems from the fact that control of effective effort, often necessary for sustainable management of the resource, remains a central management problem for that sector worldwide, even in developed countries. However, various policies put in...

A C-Band Geophysical Model Function for Determining Coastal Wind Speed Using Synthetic Aperture Radar
Provedor de dados: 5
Autores: Lu, Yiru; Zhang, Biao; Perrie, William; Mouche, Alexis; Li, Xiaofeng; Wang, He.
A new geophysical model function (GMF), called C_SARMOD2, has been developed to relate high-resolution C-band normalized radar cross section (NRCS), acquired in VV polarization over the ocean, to the 10-m height wind speed. A total of 3078 RADARSAT-2 and Sentinel-1A VV-polarized synthetic aperture radar (SAR) images, acquired under different wind speed conditions, were collocated with in situ buoy measurements. The paired dataset was used to derive transfer functions and coefficients of C_SARMOD2, and then to validate the wind speed retrievals. The comparison between SAR-retrieved wind speeds and buoy measurements show almost no bias and a root mean square error of 1.84 m/s. Two representative quad-and dual-polarization SAR images, acquired from coastal...

A census of Meddies in a long-term high-resolution simulation
Provedor de dados: 5
Autores: Barbosa Aguiar, Ana Claudia; Peliz, Alvaro; Carton, Xavier.
The output from a high-resolution two-decade long Mediterranean Outflow simulation is analysed here to provide a census of Mediterranean Water eddies (aka Meddies), both anticyclones and cyclones. The formation rate of Meddies that survive for at least 90 days is of 12 Meddies yr(-1) of which similar to 12% are cyclones. The rate of formation reaches 40 Meddies yr(-1) (30% cyclones) when considering all the Meddies living over 15 days. About 70% of the population is born along the southwestern Iberian slope, but several robust Meddles also originate in points of convergence of the main pathways into the open ocean. The longest-lived Meddies propagate northwestwards, but most of the anticyclones veer southwestwards after a while. As the Meddies drift away...

Autores: Greene, Hg; Yoklavich, Mm; Starr, Rm; O'Connell, Vm; Wakefield, Ww; Sullivan, De; Mcrea, Je; Cailliet, Gm.
A standard, universally useful classification scheme for deepwater habitats needs to be established so that descriptions of these habitats can be accurately and efficiently applied among scientific disciplines. In recent years many marine benthic habitats in deep water have been described using geophysical and biological data. These descriptions can vary from one investigator to another, which makes it difficult to compare habitats and associated biological assemblages among geographic regions. Using geophysical data collected with a variety of remote sensor systems and in situ biological and geologic observations, we have constructed a classification scheme that can be used in describing marine benthic habitats in deep water.

Provedor de dados: 5
Autores: Liu, Yi-wei; Eagle, Robert A.; Aciego, Sarah M.; Gilmore, Rosaleen E.; Ries, Justin B.
Ocean acidification will potentially inhibit calcification by marine organisms; however, the response of the most prolific ocean calcifiers, coccolithophores, to this perturbation remains under characterized. Here we report novel chemical constraints on the response of the widespread coccolithophore species Ochrosphaera neapolitana (O. neapolitana) to changing-CO2 conditions. We cultured this algae under three pCO(2)-controlled seawater pH conditions (8.05, 8.22, and 8.33). Boron isotopes within the algae's extracellular calcite plates show that this species maintains a constant pH at the calcification site, regardless of CO2-induced changes in pH of the surrounding seawater. Carbon and oxygen isotopes in the algae's calcite plates and carbon isotopes in...

A coastal ocean model intercomparison study for a three-dimensional idealised test case
Provedor de dados: 5
Autores: Tartinville, B; Deleersnijder, E; Lazure, Pascal; Proctor, R; Ruddick, Kg; Uittenbogaard, Re.
Several coastal ocean models have been used to compute the circulation on the Northwest European Continental Shelf. Five of them, developed within the European Union, are compared in the scope of an idealised three-dimensional test case, dealing with the geostrophic adjustment of a freshwater cylinder. As the central eddy adjusts, unstable baroclinic vortices start to grow. All the models are able to produce such unstable vortices. However, two of them produce an order-two instability, which is in accordance with a previous laboratory experiment, while the others exhibit an order-four instability. Using a simple scaling analysis, it is seen that the azimuthal wavenumber depends on the ratio of the kinetic energy to the available potential energy. It...

A combined microsatellite multiplexing and boiling DNA extraction method for high-throughput parentage analyses in the Pacific oyster (Crassostrea gigas)
Provedor de dados: 5
Autores: Taris, Nicolas; Baron, S; Sharbel, Tim; Sauvage, Christopher; Boudry, Pierre.
The analysis of parentage using microsatellite markers is of increasing importance, notably in aquaculture genetic research where communal rearing of mixed families can be used to reduce unwanted environmental variance. We present here an optimization of parental genotype assessment for larvae or adults of the Pacific oyster, Crassostrea gigas, using a multiplex system of three microsatellite loci. In conjunction with a simple DNA extraction protocol, this method enables high throughput analyses of parentage in C. gigas. Using this method, we successfully determined the parentage of 93% (1224 out of 1318) of the progeny in a factorial cross between 3 females and 10 males. The inability to genotype the remaining 7% was due to DNA degradation of larvae...

The MEDATLAS hydrological data base, has been created by a consortium of several data centers, including HNODC (Greece), IEO (Spain), EPSHOM/CMO (French navy), IFREMERJSISMER the coordinating center (France) and ICES (Denmark) as the supervisor of the quality control procedure, in the frame of the MEDATLAS project. This project is a MAST supporting initiative for ocean data and information management. Its objectives were to assemble a comprehensive data base of temperature and salinity profiles collected in the Mediterranean sea by t he scientific laboratories and the navies, to check them for quality and to revise the climatological statistics by using this updated date set. An important part of the work has been devoted to define a common protocol to...

Host-microbe interactions play crucial roles in marine ecosystems, but we still have very little understanding of the mechanisms that govern these relationships, the evolutionary processes that shape them, and their ecological consequences. The holobiont concept is a renewed paradigm in biology that can help describe and understand these complex systems. It posits that a host and its associated microbiota, living together in a long-lasting relationship, form the holobiont, and have to be studied together, as a coherent biological and functional unit, in order to understand the biology, ecology and evolution of the organisms. Here we discuss critical concepts and opportunities in marine holobiont research and identify key challenges in the field. We...

A co-modelling process of social and natural dynamics on the isle of Ouessant: Sheep, turf and bikes
Provedor de dados: 5
Autores: Rouan, Mathias; Kerbiriou, Christian; Levrel, Harold; Etienne, M.
An interdisciplinary team has applied the multi-agent system formalism to study shrub encroachment in the Biosphere Reserve on the isle of Ouessant. The main goals were (1) to understand vegetation dynamics, and (2) to represent how main agents, or actors view the dynamics of natural resources in relation to their own living practices. The management strategies established for each type of stakeholders were formalised and the impact of these strategies on biodiversity was analyzed at various temporal and spatial scales. Following a short description of the model, three aspects of the modelling process are discussed in more detail: the use of the chough (Pyrrhocorax pyrrhocorax) population as a representative variable for the interactions between...

A comparative analysis of Alexandrium catenella/tamarense blooms in Annaba Bay (Algeria) and Thau lagoon (France); phosphorus limitation as a trigger
Provedor de dados: 5
Autores: Hadjadji, Imene; Frehi, Hocine; Ayada, Lembarek; Abadie, Eric; Collos, Yves.
Environmental conditions ultimately leading to blooms of the toxic dinoflagellate Alexandrium catenella/tamarense were investigated at two Mediterranean sites (Annaba Bay, Algeria and Thau lagoon, France). Three years were examined in details: 1992 (a pre-Alexandrium period), 2002 (a year with the first bloom in Annaba) and 2010 (a year with a major bloom in Annaba). Most conditions were similar, but ammonium concentrations were much higher in Annaba (up to 100 μM) than in Thau (up to 10 μM). First records of A. catenella/tamarense were in 1995 for Thau and 2002 for Annaba, and coincided with soluble reactive phosphorus (SRP) decreasing below a concentration of about 1 μM. No other environmental variable could be related to those blooms. Thus, it is likely...

A comparative analysis of métiers and catch profiles for some French demersal and pelagic fleets
Provedor de dados: 5
Autores: Marchal, Paul.
A quantitative comparison between metiers and resulting catch profiles was carried out for seven French demersal and pelagic fleets operating in the North Sea, the eastern Channel, and the Bay of Biscay. Typologies for four metiers have been attempted, based on different factors (gear, mesh size, fishing ground, and/or a priori target species), data sources (logbooks or harbour enquiries), and aggregation levels. Catch profiles were selected through cluster analysis. The linkage between metiers and catch profiles was quantified using uncertainty coefficients, which depended on the metier typology being used and the fleet under consideration, but were not subject to substantial inter- or intra-annual fluctuations. Future catch profiles and metiers were...

A comparative assessment of the uncertainties of global surface ocean CO2 estimates using a machine-learning ensemble (CSIR-ML6 version 2019a) - have we hit the wall?
Provedor de dados: 5
Autores: Gregor, Luke; Lebehot, Alice D.; Kok, Schalk; Monteiro, Pedro M. Scheel.
Over the last decade, advanced statistical inference and machine learning have been used to fill the gaps in sparse surface ocean CO2 measurements (Rodenbeck et al., 2015). The estimates from these methods have been used to constrain seasonal, interannual and decadal variability in sea-air CO2 fluxes and the drivers of these changes (Landschutzer et al., 2015, 2016; Gregor et al., 2018). However, it is also becoming clear that these methods are converging towards a common bias and root mean square error (RMSE) boundary: "the wall", which suggests that pCO(2) estimates are now limited by both data gaps and scale-sensitive observations. Here, we analyse this problem by introducing a new gap-filling method, an ensemble average of six machine-learning models...

A comparative ecophysiological study of two infaunal filter-feeding bivalves: Paphia rhomboides and Glycymeris glycymeris
Provedor de dados: 5
Autores: Savina, Marie; Pouvreau, Stephane.
A comparative ecophysiological study was carried out in September and November 2002 for two bivalves, Paphia rhomboides and Glycymeris glycymeris, which are significantly harvested in the Western Channel (French coast). Individual measurements of clearance and respiration rates were performed for both species, in several experimental conditions of temperature and phytoplankton concentrations. Those conditions were chosen to be in the range of those commonly observed in the subtidal area of the Western Channel. The mean value of clearance rate and oxygen consumption obtained from continuous data recording did not reveal any significant influence of temperature in the investigated range, but a significant difference between P rhomboides and G. glycymeris....

This paper reports a comparative study of two cupped oysters, Crassostrea gigas and C angulata, and their hybrids reared in the Marennes-Oleron Sound (France) under usual farming conditions. The relative proficiency of these species was characterized in terms of growth, survival and reproduction, three major concerns for oyster farming. Four populations of each taxon were sampled (C gigas: Japan and France; C angulata: Taiwan and Spain) and used as progenitors to produce six different progenies under common hatchery and nursery conditions (transfer of 5 to 6 g of seed oysters at sea and rearing in bags for 2 years). Mortality profiles differed greatly among the progenies. The C angulata progeny of Taiwanese origin gave the poorest results, with 100%...

Intact natural gas hydrates recovered on the West Aftican margin in the South Atlantic Ocean (ZaiAngo and Neris IIrojects) and from the Norwegian Sea (Hakon Mosby Mud Volcano) are investigated by micro-Raman spectroscopy at ambient pressure and low temperature. The gas hydrates collected at different geological sites contain a high methane concentration relative to other minor components that are slightly dispersed in the samples. They crystallize in a type I cubic lattice structure as also confirmed by our preliminary synchrotron diffraction results obtained on the ZaiAngo specimen. However, detailed analysis of selected microscopic areas reveals a variation in the gas distribution among the different specimens. Trace amounts of CO2 and H2S can be...

This study compares the details and performance of fisheries management between the EU and a selection of other countries worldwide: Iceland, New Zealand, and Australia, which are considered in many respects to be among the most advanced in the world in fisheries management. Fisheries management in the EU, Iceland, Australia, and New Zealand has developed following different paths, despite being based on similar instruments and principles. Iceland, Australia, and New Zealand have been at the forefront of developing management practices such as stakeholder involvement, legally binding management targets (Australia, New Zealand), individual transferable quotas, and discard bans (Iceland, New Zealand). The EU has since the beginning of the 21st century taken...

A comparative review of the fisheries resource management systems in New Zealand and in the European Union
Provedor de dados: 5
Autores: Marchal, Paul; Lallemand, Philippe; Stokes, Kevin; Thebaud, Olivier.
This review aims at comparing the fisheries management systems existing in New Zealand and in the European Union. The involvement of stakeholders at all stages of the management process is generally more transparent and better established in New Zealand than in the EU. Both systems aim at achieving an adequate balance between sustainability and utilisation and consider the precautionary approach as a founding principle. The social objectives are probably more explicit in the EU management system. In New Zealand, B-MSY is a legal management target for all stocks in the quota management system (QMS), but management strategies were poorly explicit until most recently. In the EU, there have not been any legal management targets or strategies until 1999. Since...

Representatives of Ligophorus Euzet et Suriano, 1977 were found on the gills of Mugil liza Valenciennes caught in southern Brazil. They were identified as Ligophorus uruguayense Failla Siquier et Ostrowski de Nufiez, 2009 and Ligophorus saladensis Marcotegui et Martorelli, 2009, even though specific identification proved to be difficult due to inconsistencies in some diagnostic features reported for these two species. Therefore, a combined morphological and molecular approach was used to critically review the validity of these species, by means of phase contrast and confocal fluorescence microscopical examination of sclerotised hard parts, and assessing the genetic divergence between L. saladensis, L. uruguayense and their congeners using rDNA sequences....

Autores: Dauchez, S; Queguiner, B; Treguer, P; Zeyons, C.
Nitrogen (N-15) and carbon (C-14) uptake rates and hydrological, chemical and biological parameters were monitored at a single station during spring (March-April 1989) in a coastal eutrophic ecosystem of western Europe : the Bay of Brest. Before the spring growth of phytoplankton populations, total nitrogen and carbon uptake rates were low (almost-equal-to 0.3-mu-mol C.1(-1).h-1 and almost-equal-to 0.025-mu-mol N.l(-1).h-1). During the spring bloom, these uptake rates reached high values (0.5-mu-mol C.1(-1).h-1 and 0.28-mu-mol N.1(-1).h-1); at this time, nitrate was the main source of nitrogen production, although relative preference index (RPI) values showed that ammonium was the preferred nitrogen form for phytoplankton (RPI (NO3) &lt; 1 ; RPI (NH4) &gt;...

Autores: Le Floc'H, P.; Daures, Fabienne; Brigaudeau, Cecile; Bihel, J.
Indicators of the economic performance of fishing vessels are frequently computed in various countries. In this paper, we use different types of information to assess capital value and the economic performance of fishing vessels. On the one hand, field surveys provide technical and financial information on the main components of fishing capital. On the other hand, book values are given in bookkeeping databases. Both sources of information on fishing capital are used for the same set of vessels, namely the commercial fishing fleet of the French region of Brittany. Based on these two sources, measures of economic performance can be produced for the short term using gross surplus; and for the long term including the cost of capital. The measures of...

The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from...

The objective of this study was to assess the impact of the filtration method (in situ vs. ex situ) on the dissolved/particulate partitioning of 12 elements in hydrothermal samples collected from the Lucky Strike vent field (Mid-Atlantic Ridge; MAR). To do so, dissolved ( &lt;0.45 mu m) and particulate Mg, Li, Mn, U, V, As, Ba, Fe, Zn, Cd, Pb and Cu were measured using different techniques (HR-ICP-MS, ICP-AES and CCSA). Using in situ filtration as a baseline, we showed that ex situ filtration (on-board and on shore after freezing) resulted in an underestimation of the dissolved pool, which was counterbalanced by an overestimation of the particulate pool for almost all the elements studied. We also showed that on-board filtration was acceptable for the...

Provedor de dados: 5
Autores: Ducet, N; Le Traon, Pierre-yves.
Analyses of surface eddy kinetic energy (EYE) inferred from 5 years of merged TOPEX/Poseidon and ERS-1/2 altimetric data are presented in the Gulf Stream (GS) and the Kuroshio (KS) Current systems, focusing on anisotropy and EKE seasonal, interannual, and long-term variations, as well as Reynolds stresses. For both GS and KS a descriptive analysis of the EKE field shows that it is anisotropic along the path of the currents and assesses the close relationship between the spatial distribution of EKE high levels and bottom topography. A striking ocean feature is found in the GS, shaped as a zonal "double-blade" structure in the EKE field, centered at 37 degrees N, 71.5 degrees W, that likely corresponds to a regular and permanent lateral displacement of the...

Polar cod (Boreogadus saida) is one of the most studied Arctic marine fishes given its circumpolar distribution and centralised role in the Arctic marine food web. In contrast, relatively little is known about two other Arctic Gadidae: saffron cod (Eleginus gracilis) and Greenland cod (Gadus ogac). Climate change is expected to have an effect on sea ice-associated species, such as polar cod, but due to our lack of knowledge of other arctic gadid species it remains unclear how climate change will impact them and their interactions within the arctic marine ecosystem. Here, we explored the ecology of three Arctic Gadidae that co-occur in the Canadian Beaufort Sea. Stable isotope (SI) (niche overlap) and fatty acid (FA) (correspondence analysis and linear...

Estimating the current risk of coastal flooding requires adequate information on extreme sea levels. For over a decade, the only global data available was the DINAS-COAST Extreme Sea Levels (DCESL) dataset, which applies a static approximation to estimate extreme sea levels. Recently, a dynamically derived dataset was developed: the Global Tide and Surge Reanalysis (GTSR) dataset. Here, we compare the two datasets. The differences between DCESL and GTSR are generally larger than the confidence intervals of GTSR. Compared to observed extremes, DCESL generally overestimates extremes with a mean bias of 0.6m. With a mean bias of -0.2m GTSR generally underestimates extremes, particularly in the tropics. The Dynamic Interactive Vulnerability Assessment model is...

Two techniques of stock discrimination both utilizing scales, i. e. termed as classical technique and shape analysis, are compared for discriminating between North American and European Atlantic salmon (Salmo salar L.) caught off West Greenland. Three scales from each of 60 salmon were analyzed: 30 from North American and 30 from European-origin salmon collected from home rivers in 1982. The best results indicated misclassification and error rates of 0% for shape analysis and 5.0% and ± 1.7%, respectively, for the classical technique. A nested ANOVA indicated that variation was greater between scales of salmon of North American and European origin than from several scales from the same salmon. It was concluded that shape analysis with computer-aided...

A comparison of various fitting techniques for predicting yield for the Ubolratana reservoir (Thailand) from a time series data on catch and hydrological features
Provedor de dados: 5
Autores: Moreau, Jacques; Lek, Sovan; Leelaprata, Wattana; Sricharoendham, Boonsong; Villanueva, Ching-maria.
Actual catch (commercial catch and local consumption) have been made available by the Royal Thai Department of Fisheries for the Ubolratana reservoir, North East Thailand, since the impoundment of the lake in 1965. The data have been used to assess the possible relationship between the actual catch and morphometric parameters of the lake (maximum area, depth, shore line, difference between maximum and minimum area) and actual catch the year before. A comparison of the predictive power is carried out between multiple linear regression analysis, a generalised additive model, a regression tree analysis, an autoregression analysis and an artificial neural network. Results show the poorly predictive power in linear system (around 40% of explained variances),...

A compilation of Europe-wide databases from published measurements of PCBs, Dioxins and Furans
Provedor de dados: 5
Autores: Institute for Environment and Sustainability (Joint Research Centre).
Chemical risk assessment always entails an evaluation of expected environmental concentrations of substances; these concentrations may be predicted using mathematical models or may be chosen on the basis of experimental observations and monitoring activities. The work discusses the usefulness and limitations in building compilations of published monitoring data by describing a feasibility study on polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-pdioxins and dibenzofurans (PCDD/Fs), for which observed concentration data were retrieved from scientific journal articles published between 2000 and 2009. These chemicals are typical POPs and are of constantly high concern for their potential adverse effects on human health and ecosystems. PCBs were...

A complementary method for production of tetraploid Crassostrea gigas using crosses between diploids and tetraploids with cytochalasin B treatments
Provedor de dados: 5
Autores: Mccombie, Helen; Ledu, Christophe; Phelipot, Pascal; Lapegue, Sylvie; Boudry, Pierre; Gerard, Andre.
We present a new method to produce tetraploid Crassostrea gigas by cytochalasin B inhibition of polar body 2 expulsion in diploid females crossed with tetraploid males. This offers a means of direct introgression of genetic characters from selected diploid to tetraploid lines, avoiding a triploid step. Offspring larval ploidy shifted over time and depended on size, with tetraploids more frequent among the smaller larvae and triploids among the large. Viable tetraploids were found at 4 and 6 months, indicating the technique was successful. The possibility that gynogenesis occurred was tested by microsatellite analysis to confirm the presence of paternally inherited alleles. These were present in all animals of the 2n x 4n + CB (female first) cross. However,...

The equatorial eastern Indian Ocean hosts a diffuse plate boundary, where widespread deformation accommodates the relative motion between the Indian, Australian and Capricorn sub-plates. We integrate IODP Expedition 362 borehole data, which for the first time provides an accurate, ground-truthed chronostratigraphy of the sedimentary sequence east of the Ninety East Ridge (NER), with 2D seismic reflection profiles and multibeam bathymetry to assess the styles of faulting between the NER and the Sunda subduction zone, timing of activity and comparison with physical and rheological properties. We identify four distinct fault sets east of the NER in the northern Wharton Basin. N-S (350-010°) orientated faults, associated with the N-S fracture zones formed at...

A complex North Atlantic permanent pycnocline revealed by Argo data
Provedor de dados: 5
Autores: Feucher, Charlene; Maze, Guillaume; Mercier, Herle.
In the North Atlantic subtropical gyre, the oceanic vertical structure of density is characterized by a region of rapid increase with depth. This layer is called the permanent pycnocline. The pycnocline is the transition layer between light, low-latitude, surface water masses which are ventilated every winter when penetrated locally by the mixed layer and dense, deeper water masses whose properties are set in the high latitudes.  Assessing the structure and variability of the permanent pycnocline is of a major interest in the under- standing of the climate system because the pycnocline embeds the warm water sphere and most of the wind-forced horizontal circulation.  We characterized the large scale structure of the permanent pycnocline with in-situ data...

Velocity measurements collected by an upward-looking acoustic Doppler current profiler were used to provide the first study of ambient turbulence in Alderney Race. Turbulence metrics were estimated at mid-depth during peak flooding and ebbing tidal conditions. The dissipation rate ε and the integral lengthscale (L) were estimated using two independent methods: the spectral method and the structure function method. The spectral method provided ε and (L) estimates with standard deviations twice lower than that obtained from the structure function method. Removal of wave and Doppler noise-induced bias when estimating the dissipation rate was shown to be a crucial step in turbulence characterization. It allowed for a significant refining in (L) estimates...

Two different sample preparation protocols for the determination of 37 emerging and historical halogenated flame retardants (HFRs) in marine tissues were compared with regards to extraction recovery, lipid removal efficiency, repeatability, reproducibility, and ability to measure sub-ng g−1 (dry weight) concentrations in marine biota. One method involved a purification step using gel permeation chromatography (GPC) followed by a HPLC fractionation step on a Partisil amino-cyano normal phase (GPC-Partisil procedure) and the other more traditional method was based on sulphuric acid treatment followed by silica column fractionation (H2SO4-silica procedure).

Large clastic cliff-top storm deposits (called CTSDs) are one of the most remarkable signatures that characterizes extreme storm wave events on coastal cliffs. Hence, the study of CTSDs is of key importance for understanding and predicting the impacts of extreme storm wave events on rocky coasts or establishing proxies for storm intensity. The present study uses new data including hydrodynamic measurements in both deep and intertidal waters, and records of CTSDs displacement and deposition across Banneg Island during the stormy winter 2013–2014. Two drone-based surveys were carried out in January 2013 (pre-storms) and in April 2014 (post-storms). In addition, complementary field observations were carried out during the winter, providing a comprehensive and...

A comprehensive oceanographic dataset of a subpolar, mid-latitude broad fjord: Fortune Bay, Newfoundland, Canada
Provedor de dados: 5
Autores: Donnet, Sebastien; Lazure, Pascal; Ratsimandresy, Andry; Han, Guoqi.
While the dynamics of narrow fjords, i.e. narrow with respect to their internal Rossby radius, have been widely studied, it is only recently that interest sparked in studying the physics of broad fjords due to their importance in glacial ice melting (in Greenland, especially). Here, we present a comprehensive set of data collected in Fortune Bay, a broad, mid-latitude fjord located on the Northwest Atlantic shores. Aside from being wide (15–25 km width) and deep (600 m at its deepest), Fortune Bay also has the characteristics of having steep slopes, weak tides and of being strongly stratified from spring to fall. Thus, and since strong along-shore winds also characterise the region, this system is prone to interesting dynamics, generally taking the form of...

A software has been developed to overcome the difficulties related to depositional model determination in Geosciences. The implemented methods, Walker, Harper and Turk methods, based on Markov process and Markov chain analysis, have been used in a case study. The results of the analysis are consistent with previous works. The analysis shows also that the results are accurate and do not rely on the used method. Therefore, the obtained depositional sequence is suitable to build a depositional model on which reliable sequence stratigraphic studies can be based.

A Conservative Model for Nonlinear Dynamics in a Stratified, Rotating Fluid
Provedor de dados: 5
Autores: Filatoff, Nicolas; Carton, Xavier.
We present a set of equations describing the nonlinear dynamics of flows constrained by environmental rotation and stratification (Rossby numbers Ro∈[0.1,0.5] and Burger numbers of order unity). The fluid is assumed incompressible, adiabatic, inviscid and in hydrostatic balance. This set of equations is derived from the Navier Stokes equations (with the above properties), using a Rossby number expansion with second order truncation. The resulting model has the following properties: 1) it can represent motions with moderate Rossby numbers and a Burger number of order unity; 2) it filters inertia-gravity waves by assuming that the divergence of horizontal velocity remains small; 3) it is written in terms of a single function of space and time (pressure,...

A continuous hockey stick stock-recruit model for estimating MSY reference points
Provedor de dados: 5
Autores: Mesnil, Benoit; Rochet, Marie-joelle.
With political commitment to restore stocks to levels where they can produce maximum sustainable yield (MSY), fisheries managers request evaluations of management plans that include options for an FMSY policy. The procedure to estimate FMSY with dynamic-pool, stock assessment models is well established for common stock-recruitment relationships (S-RR). In this paper, we extend this capacity to another S-RR, a piecewise function known as the hockey stick, which is frequently assumed when the data do not support more elaborate functions. However, the hockey stick is not continuous, which makes it problematic for this application, where differentiable functions are required. The bent-hyperbola model proves to be an adequate continuous equivalent to the hockey...

A continuous model of biomass size spectra governed by predation and the effects of fishing on them
Provedor de dados: 5
Autores: Benoit, Eric; Rochet, Marie-joelle.
A new time-dependent continuous model of biomass size spectra is developed. In this model, predation is the single process governing the energy flow in the ecosystem, as it causes both growth and mortality. The ratio of predator to prey is assumed to be distributed: predators may feed on a range of prey sizes. Under these assumptions, it is shown that linear size spectra are stationary solutions of the model. Exploited fish communities are simulated by adding fishing mortality to the model: it is found that realistic fishing should affect the curvature and stability of the size spectrum rather than its slope.

Volcanic ash preserved in marine sediment sequences is key for independent synchronization of palaeoclimate records within and across different climate archives. Here we present a continuous tephrostratigraphic record from the Labrador Sea, spanning the last 65.5 ka, an area and time period that has not been investigated in detail within the established North Atlantic tephra framework. We investigated marine sediment core GS16]204] 22CC for increased tephra occurrences and geochemically analysed the major element composition of tephra shards to identify their source volcano(es). In total we observed eight tephra zones, of which five concentration peaks show isochronous features that can be used as independent tie]points in future studies. The main...

A cooperative and specific DNA-binding mode of HIV-1 integrase depends on the nature of the metallic cofactor and involves the zinc-containing N-terminal domain
Provedor de dados: 5
Autores: Carayon, Kevin; Leh, Herve; Henry, Etienne; Simon, Francoise; Mouscadet, Jean-francois; Deprez, Eric.
HIV-1 integrase catalyzes the insertion of the viral genome into chromosomal DNA. We characterized the structural determinants of the 3'-processing reaction specificity-the first reaction of the integration process-at the DNA-binding level. We found that the integrase N-terminal domain, containing a pseudo zinc-finger motif, plays a key role, at least indirectly, in the formation of specific integrase-DNA contacts. This motif mediates a cooperative DNA binding of integrase that occurs only with the cognate/viral DNA sequence and the physiologically relevant Mg(2+) cofactor. The DNA-binding was essentially non-cooperative with Mn(2+) or using non-specific/random sequences, regardless of the metallic cofactor. 2,2'-Dithiobisbenzamide-1 induced zinc ejection...

A Correction for the Thermal Mass-Induced Errors of CTD Tags Mounted on Marine Mammals
Provedor de dados: 5
Autores: Mensah, Vigan; Roquet, Fabien; Siegelman-charbit, Lia; Picard, Baptiste; Pauthenet, Etienne; Guinet, Christophe.
The effect of thermal mass on the salinity estimate from conductivity-temperature-depth (CTD) tags sensor mounted on marine mammals is documented, and a correction scheme is proposed to mitigate its impact. The algorithm developed here allows for a direct correction of the salinity data, rather than a correction of the sample's conductivity and temperature. The amplitude of the thermal mass-induced error on salinity and its correction are evaluated via comparison between data from CTD tags and from Sea-Bird Scientific CTD used as a reference. Thermal mass error on salinity appears to be generally O(10(-2)) g kg(-1), it may reach O(10(-1)) g kg(-1), and it tends to increase together with the magnitude of the cumulated temperature gradient (T-HP) within the...

A cost-benefit analysis of improving trawl selectivity in the case of discards: The Nephrops norvegicus fishery in the Bay of Biscay
Provedor de dados: 5
Autores: Macher, Claire; Guyader, Olivier; Talidec, Catherine; Bertignac, Michel.
The Nephrops trawl fishery is one of the most important fisheries in the Bay of Biscay. The fishery management essentially relies on conservation measures, a total at I owed catch (TAC) for Nephrops together with a mini mum landing size (MLS) and minimum trawl mesh size (70 mm stretched mesh). These measures have failed to prevent high discard levels of many species that characterize the fishery. Nephrops trawlers thus discard about half of their Nephrops catches in numbers (a third in weight) of which only 30% survive. Nephrops discards mainly occur in younger Nephrops age groups below the MLS. This is a waste for the already overexploited Nephrops stock as well as for the fleet. Based on a bio-economic simulation model, the paper analyses the...

A cost-effectiveness analysis of alternative survey methods used for the monitoring of marine recreational fishing in France
Provedor de dados: 5
Autores: Bellanger, Manuel; Levrel, Harold.
The growth of marine recreational activities raises the issues of the current lack of knowledge on these activities and the information required to assess their potential impacts. Indeed, the monitoring of unrecorded activities is a great challenge, especially when basic information, such as the size of the population practicing the different activities, is unknown. In this paper, the experience of the monitoring of marine recreational fishing was used to carry out a diagnosis study to assess the cost-effectiveness of survey methods used in France between 2004 and 2012. Costs of alternative surveys were balanced with data quality, and particular attention was paid to potential biases. Results showed that the involvement of citizens through diary surveys...

In this paper we used a modelling approach integrating both physical and biological constraints to understand the biogeographical distribution of the great scallop Pecten maximus in the English Channel during its whole life cycle. A 3D bio-hydrodynamical model (ECO-MARS3D) providing environmental conditions was coupled to (i) a population dynamics model and (ii) an individual ecophysiological model (Dynamic Energy Budget model). We performed the coupling sequentially, which underlined the respective role of biological and physical factors in defining P. maximus distribution in the English Channel. Results show that larval dispersion by hydrodynamics explains most of the scallop distribution and enlighten the main known hotspots for the population,...

A coupled climate model simulation of Marine Isotope Stage 3 stadial climate
Provedor de dados: 5
Autores: Brandefelt, J.; Kjellstrom, E.; Naslund, J. -o.; Strandberg, G.; Voelker, A. H. L.; Wohlfarth, B.
We present a coupled global climate model (CGCM) simulation, integrated for 1500 yr to quasi-equilibrium, of a stadial (cold period) within Marine Isotope Stage 3 (MIS 3). The simulated Greenland stadial 12 (GS12; similar to 44 ka BP) annual global mean surface temperature (T-s) is 5.5 degrees C lower than in the simulated recent past (RP) climate and 1.3 degrees C higher than in the simulated Last Glacial Maximum (LGM; 21 ka BP) climate. The simulated GS12 is evaluated against proxy data and previous modelling studies of MIS3 stadial climate. We show that the simulated MIS 3 climate, and hence conclusions drawn regarding the dynamics of this climate, is highly model-dependent. The main findings are: (i) Proxy sea surface temperatures (SSTs) are higher...

A Coupled Lagrangian-Earth System Model for Predicting Oil Photooxidation
Provedor de dados: 5
Autores: Vaz, Ana C; Faillettaz, Robin; Paris, Claire B.
During the Deepwater Horizon (DWH) blowout, photooxidation of surface oil led to the formation of persistent photooxidized compounds, still found in shoreline sediments a decade later. Studies demonstrated that photooxidation modified both biodegradation rates of the surface oil and the effectiveness of aerial dispersant applications. Despite the significant consequences of this weathering pathway, the lack of measurements prevented photooxidation to be accounted for in the DWH oil budget calculations and in most predictive models. Here we develop a Lagrangian photooxidation module that estimates the dose of solar radiation individual oil droplets receive while moving in the ocean, quantifies the likelihood of photooxidative changes, and continues to track...

A coupled movement and bioenergetics model to explore the spawning migration of anchovy in the Bay of Biscay
Provedor de dados: 5
Autores: Politikos, Dimitrios; Huret, Martin; Petitgas, Pierre.
Adult anchovies in the Bay of Biscay perform north to south migration from late winter to early summer for spawning. However, what triggers and drives the geographic shift of the population remains unclear and poorly understood. An individual-based fish model has been implemented to explore the potential mechanisms that control anchovy's movement routes toward its spawning habitats. To achieve this goal, two fish movement behaviors – gradient detection through restricted area search and kinesis – simulated fish response to its dynamic environment.

A "critical" climatic evaluation of last interglacial (MIS 5e) records from the Norwegian Sea
Provedor de dados: 5
Autores: Bauch, Henning A.; Erlenkeuser, Helmut.
Sediment cores from the Norwegian Sea were studied to evaluate interglacial climate conditions of the marine isotope stage 5e (MIS 5e). Using planktic forminiferal assemblages as the core method, a detailed picture of the evolution of surface water conditions was derived. According to our age model, a step-like deglaciation of the Saalian ice sheets is noted between ca. 135 and 124.5 Kya, but the deglaciation shows little response with regard to surface ocean warming. From then on, the rapidly increasing abundance of subpolar forminifers, concomitant with decreasing iceberg indicators, provides evidence for the development of interglacial conditions sensu stricto (5e-ss), a period that lasted for about 9 Ky. As interpreted from the foraminiferal records,...

A current synthesis on the effects of electric and magnetic fields emitted by submarine power cables on invertebrates
Provedor de dados: 5
Autores: Albert, Luana; Deschamps, François; Jolivet, Aurélie; Olivier, Frédéric; Chauvaud, Laurent; Chauvaud, Sylvain.
The goal of clean renewable energy production has promoted the large-scale deployment of marine renewable energy devices, and their associated submarine cable network. Power cables produce both electric and magnetic fields that raise environmental concerns as many marine organisms have magneto and electroreception abilities used for vital purposes. Magnetic and electric fields' intensities decrease with distance away from the cable. Accordingly, the benthic and the sedimentary compartments are exposed to the highest field values. Although marine invertebrate species are the major fauna of these potentially exposed areas, they have so far received little attention. We provide extensive background knowledge on natural and anthropogenic marine sources of...

A data assimilating model for estimating Southern Ocean biogeochemistry
Provedor de dados: 5
Autores: Verdy, A.; Mazloff, M. R.
A Biogeochemical Southern Ocean State Estimate (B-SOSE) is introduced that includes carbon and oxygen fields as well as nutrient cycles. The state estimate is constrained with observations while maintaining closed budgets and obeying dynamical and thermodynamic balances. Observations from profiling floats, shipboard data, underway measurements, and satellites are used for assimilation. The years 2008-2012 are chosen due to the relative abundance of oxygen observations from Argo floats during this time. The skill of the state estimate at fitting the data is assessed. The agreement is best for fields that are constrained with the most observations, such as surface pCO(2) in Drake Passage (44% of the variance captured) and oxygen profiles (over 60% of the...

A data set of sea surface stereo images to resolve space-time wave fields

Autores: Guimarães, Pedro Veras; Ardhuin, Fabrice; Bergamasco, Filippo; Leckler, Fabien; Filipot, Jean-francois; Shim, Jae-seol; Dulov, Vladimir; Benetazzo, Alvise.
Stereo imaging of the sea surface elevation provides unique field data to investigate the geometry and dynamics of oceanic waves. Typically, this technique allows retrieving the 4-D ocean topography (3-D space + time) at high frequency (up to 15–20 Hz) over a sea surface region of area ~104 m2. Stereo data fill the existing wide gap between sea surface elevation time-measurements, like the local observation provided by wave-buoys, and large-scale ocean observations by satellites. The analysis of stereo images provides a direct measurement of the wavefield without the need of any linear-wave theory assumption, so it is particularly interesting to investigate the nonlinearities of the surface, wave-current interaction, rogue waves, wave breaking, air-sea...

A DEB based analysis of growth and toxin elimination processes in mussels (Mytilus edulis) exposed to Diarrhetic Shellfish Toxins (DST)
Provedor de dados: 5
Autores: Rosland, Rune; Alunno-bruscia, Marianne; Duinker, Arne; Strand, Oivind; Strohmeier, Tore.
A Dynamic Energy Budget(DEB) model was used to analyse growth and toxin elimination processes in musselsthat had been exposed to Diarrhetic Shellfish Toxins (DST). After DST exposure mussels were placed inan experimentalin-situ setup, expected to have low concentrations of toxic phytoplankton, and DST concentrations in mussel tissueswere regularly monitored along with temperature and seston concentration and composition in the water. A one-compartment model for DST concentrations and elimination rate was integrated with the DEB model, assuming that storage and structural compartments absorb DST. The model was used to simulate growth and toxin elimination rates from mussel tissues. Toxin elimination rate was obtained by a calibration between observed and...

A DEB model to predict accumulation and detoxification of paralytic shellfish toxins by the Japanese Oyster (Crassostrea gigas)
Provedor de dados: 5
Autores: Pousse, Emilien; Jean, Frédéric; Alunno-bruscia, Marianne; Flye Sainte Marie, Jonathan.
France being the largest consumer of oysters in Europe, oyster farming is deeply rooted in French heritage. The Japanese oyster (Crassostrea gigas) is the oyster species the most exploited in France, and in the world. Due to filter-feeding, these bivalves are sensitive to toxic algal blooms. Although not always lethal, toxic algae can affect oyster physiology and make it unfit for human consumption. Phytoplankton toxins can be classified in several groups: amnesic, neurotoxic, diarrhetic and paralytic. For the latter group, saxitoxins are synthesized by the microalgae of genus Alexandrium that can accumulate bivalve tissues.  In recent years, number of studies have been performed on the interactions between C. gigas and saxitoxins. In order to better...

A decadal-scale Holocene sea surface temperature record from the subpolar North Atlantic constructed using diatoms and statistics and its relation to other climate parameters
Provedor de dados: 5
Autores: Berner, K. S.; Koc, N.; Divine, D.; Godtliebsen, F.; Moros, M.
A sediment core from Reykjanes Ridge has been studied at 10- to 50-year time resolution to document variability of Holocene surface water conditions in the western North Atlantic and to evaluate effects of Holocene ice-rafting episodes. Diatom assemblages are converted to quantitative sea surface temperatures (SST) using three different transfer functions. Spectral and scale-space methods are also applied on the records to explore variability at different timescales. Diatom assemblage and SST records clearly show that decaying remnants of the Laurentide ice sheet strongly influenced early Holocene climate in the western North Atlantic. This overrode the predominance of Milankovitch forcing, which played a key role in the development of Holocene climate in...

A decision-making framework to reduce the risk of collisions between ships and whales
Provedor de dados: 5
Autores: Sèbe, Maxime; Kontovas, Christos, A.; Pendleton, Linwood.
Ship strikes are one of the main human-induced threats to whale survival. A variety of measures have been used or proposed to reduce collisions and subsequent mortality of whales. These include operational measures, such as mandatory speed reduction, or technical ones, such as detection tools. There is, however, a lack of a systematic approach to assessing the various measures that can mitigate the risk of ship collisions with whales. In this paper, a holistic approach is proposed to evaluate mitigation measures based on a risk assessment framework that has been adopted by the International Maritime Organization (IMO), namely the Formal Safety Assessment (FSA). Formal Safety Assessment (FSA) is “a rational and systematic process for assessing the risk...

A Deep Learning approach to spatiotemporal SSH interpolation and estimation of deep currents in geostrophic ocean turbulence
Provedor de dados: 5
Autores: Manucharyan , Georgy E.; Siegelman , Lia; Klein, Patrice.
Satellite altimeters provide global observations of sea surface height (SSH) and present a unique dataset for advancing our theoretical understanding of upper ocean dynamics and monitoring its variability. Considering that mesoscale SSH patterns can evolve on timescales comparable to or shorter than satellite return periods, it is challenging to accurately reconstruct the continuous SSH evolution as currently available altimetry observations are still spatially and temporally sparse. Here we explore the possibility of SSH interpolation via Deep Learning by using synthetic observations from an idealized quasigeostrophic (QG) model of baroclinic ocean turbulence. We demonstrate that Convolutional Neural Networks with Residual Learning are superior in SSH...

A deep-sea agglutinated foraminifer tube constructed with planktonic foraminifer shells of a single species
Provedor de dados: 5
Autores: Pearson, Paul N.; Iodp Expedition 363 Shipboard Scientific Party,.
Agglutinated foraminifera are marine protists that show apparently complex behaviour in constructing their shells, involving selecting suitable sedimentary grains from their environment, manipulating them in three dimensions, and cementing them precisely into position. Here we illustrate a striking and previously un-described example of complex organisation in fragments of a tube-like foraminifer (questionably assigned to Rhabdammina) from 1466m water depth on the northwest Australian margin. The tube is constructed from well-cemented siliciclastic grains which form a matrix into which hundreds of planktonic foraminifer shells are regularly spaced in apparently helical bands. These shells are of a single species, Turborotalita clarkei, which has been...

A Design and Analysis Methodology for Component-Based Real-Time Architectures of Autonomous Systems
Provedor de dados: 5
Autores: Gobillot, Nicolas; Lesire, Charles; Doose, David.
The integration of autonomous robots in real applications is a challenge. It needs that the behaviour of these robots is proved to be safe. In this paper, we focus on the real-time software embedded on the robot, and that supports the execution of safe and autonomous behaviours. We propose a methodology that goes from the design of component-based software architectures using a Domain Specific Language, to the analysis of the real-time constraints that arise when considering the safety of software applications. This methodology is supported by a code generation toolchain that ensures that the code eventually executed on the robot is consistent with the analysis performed. This methodology is applied on a ground robot exploring an area. Categories (2), (3)

A deterministic population dynamics model to study the distribution of a benthic bivalve with planktonic larvae (Paphia rhomboides) in the English Channel (NW Europe)
Provedor de dados: 5
Autores: Savina, Marie; Menesguen, Alain.
This paper describes the development of a modelling framework to study the distribution in the English Channel of a benthic bivalve with planktonic larvae, Paphia rhomboides. Age-structured population dynamics and growth models are linked together to a compartmental transport and NPZ (Nutrients-Phytoplankton-Zooplankton) model. Used in a spin-up mode, i.e. with identical environmental forcing from a year to the next, this deterministic model converges to the same steady state whatever the initial conditions, after 15-30 years of simulation. Important features of the P. rhomboides distribution are reproduced, particularly its high abundance in the GNB (Golfe Normand-Breton) and its almost complete absence in the Western Channel. The results are discussed in...

The eastern English Channel, which connects the Atlantic Ocean to the North Sea through the Dover Strait, is an area where numerous and often conflicting human activities take place. A cross-border multidisciplinary project called CHARM was initiated to provide knowledge and tools for planners and decision-makers to durably manage the shared marine living resources. One such tool was an atlas of fish spatial distributions and modelled habitats, which was used here to investigate ontogenic and seasonal shifts in fish spatial distribution and habitat through a case-study, the dab Limanda limanda. Survey data for several life-history stages (eggs, larvae, coastal nurseries, &lt; and &gt; 1 year old) and seasons were used to map spatial patterns (using...

The lipids of a deep-sea hydrothermal vent arch ae on, Thermococcus S 557, were isolated, purified and structurally determined. Based on acid methanolysis and spectroscopic studies, the polar lipids were shown to comprise diphytanyl glycerol and dibiphytanyl diglycerol, typical membrane lipids of Arch aea. From the neutral lipids, 2,3-di-O-dihydro-14,15-geranylgeranyl glycerol was isolated. This novel ether lipid is, very likely, a close intermediate in the biosynthesis of diphytanyl glycerol diether in Arch aea.

A direct determination of the World Ocean barotropic circulation
Provedor de dados: 5
Autores: De Verdiere, Alain Colin; Ollitrault, Michel.
The time-mean Argo float displacements and the World Ocean Atlas 2009 temperature–salinity climatology are used to obtain the total, top to bottom, mass transports. Outside of an equatorial band, the total transports are the sum of the vertical integrals of geostrophic- and wind-driven Ekman currents. However, these transports are generally divergent, and to obtain a mass conserving circulation, a Poisson equation is solved for the streamfunction with Dirichlet boundary conditions at solid boundaries. The value of the streamfunction on islands is also part of the unknowns. This study presents and discusses an energetic circulation in three basins: the North Atlantic, the North Pacific, and the Southern Ocean. This global method leads to new estimations of...

A distal 140 kyr sediment record of Nile discharge and East African monsoon variability
Provedor de dados: 5
Autores: Ehrmann, Werner; Schmiedl, Gerhard; Seidel, Martin; Krueger, Stefan; Schulz, Hartmut.
Clay mineral assemblages in a sediment core from the distal Nile discharge plume off Israel have been used to reconstruct the late Quaternary Nile sediment discharge into the eastern Mediterranean Sea (EMS). The record spans the last ca. 140 kyr. Smectite abundances indicate the influence of the Blue Nile and the Atbara River that have their headwaters in the volcanic rocks of the Ethiopian Highlands. Kaolinite abundances indicate the influence of wadis, which contribute periodically to the suspension load of the Nile. Due to the geographical position, the climate and the sedimentary framework of the EMS is controlled by two climate systems. The long-term climate regime was governed by the African monsoon that caused major African humid periods (AHPs) with...

A dual sensor device to estimate fluid flow velocity at diffuse hydrothermal vents
Provedor de dados: 5
Autores: Sarrazin, Jozee; Rodier, Philippe; Tivey, M. K.; Singh, H.; Schultz, A.; Sarradin, Pierre-marie.
Numerous attempts have been made over the last thirty years to estimate fluid flow rates at hydrothermal vents, either at the exit of black smoker chimneys or within diffuse flow areas. In this study, we combine two methods to accurately estimate fluid flow velocities at diffuse flow areas. While the first method uses a hot film anemometer that performs high-frequency measurements, the second allows a relatively rapid assessment of fluid flow velocity through video imagery and provides in situ data to calibrate the sensor. Measurements of flow velocities on hydrothermal diffuse flow areas were obtained on the Mid-Atlantic Ridge (MAR). They range from 1.1 to 4.9 mm/s at the substratum level, in low-temperature (4.5-16.4 degrees C) diffuse flow areas from...

Bathymodiolus azoricus and Bathymodiolus puteoserpentis are symbiont-bearing mussels that dominate hydrothermal vent sites along the northern Mid-Atlantic Ridge (MAR). Both species live in symbiosis with two physiologically and phylogenetically distinct Gammaproteobacteria: a sulfur-oxidizing chemoautotroph and a methane-oxidizer. A detailed analysis of mussels collected from four MAR vent sites (Menez Gwen, Lucky Strike, Rainbow, and Logatchev) using comparative 16S rRNA sequence analysis and fluorescence in situ hybridization (FISH) showed that the two mussel species share highly similar to identical symbiont phylotypes. FISH observations of symbiont distribution and relative abundances showed no obvious differences between the two host species. In...

A dual-frequency approach for retrieving sea surface wind speed from TOPEX altimetry
Provedor de dados: 5
Autores: Chen, G; Chapron, Bertrand; Ezraty, Robert; Vandemark, D.
More than a dozen of wind speed (U) algorithms have been proposed during the past 2 decades, as a result of a continuing effort to improve altimeter wind measurement. The progress in terms of accuracy, however, is seen to be rather slow. The reported root mean square (RMS) error of prevailing algorithms varies mostly between 1.6 and 2.0 m/s for the dominant wind regime. As far as the TOPEX altimeter is concerned, three measured quantities, namely, the radar cross sections from Ku and C band (sigma(Ku) and sigma(C)), as well as the significant wave height (H-s), have been used in previous algorithm developments, resulting in a variety of single-, dual-, and three-parameter model functions. On the basis of the finding of a banded dependency of the...

A dynamic and mechanistic model of PCB bioaccumulation in the European hake (Merluccius merluccius)
Provedor de dados: 5
Autores: Bodiguel, Xavier; Maury, Olivier; Mellon-duval, Capucine; Roupsard, Francois; Le Guellec, Anne-marie; Loizeau, Veronique.
Bioaccumulation is difficult to document because responses differ among chemical compounds, with environmental conditions, and physiological processes characteristic of each species. We use a mechanistic model, based on the Dynamic Energy Budget (DEB) theory, to take into account this complexity and study factors impacting accumulation of organic pollutants in fish through ontogeny. The bioaccumulation model proposed is a comprehensive approach that relates evolution of hake PCB contamination to physiological information about the fish, such as diet, metabolism, reserve and reproduction status. The species studied is the European hake (Merluccius merluccius, L. 1758). The model is applied to study the total concentration and the lipid normalised...

A Dynamic Energy Budget (DEB) Model for the Keystone Predator Pisaster ochraceus
Provedor de dados: 5
Autores: Monaco, Cristian; Wethey, David S.; Helmuth, Brian.
We present a Dynamic Energy Budget (DEB) model for the quintessential keystone predator, the rocky-intertidal sea star Pisaster ochraceus. Based on first principles, DEB theory is used to illuminate underlying physiological processes (maintenance, growth, development, and reproduction), thus providing a framework to predict individual-level responses to environmental change. We parameterized the model for P. ochraceus using both data from the literature and experiments conducted specifically for the DEB framework. We devoted special attention to the model's capacity to (1) describe growth trajectories at different life-stages, including pelagic larval and post-metamorphic phases, (2) simulate shrinkage when prey availability is insufficient to meet...

A dynamic explanation for the origin of the western Mediterranean organic-rich layers
Provedor de dados: 5
Autores: Rogerson, M.; Cacho, I.; Jimenez-espejo, F.; Reguera, M. I.; Sierro, F. J.; Martinez-ruiz, F.; Frigola, J.; Canals, M.
The eastern Mediterranean sapropels are among the most intensively investigated phenomena in the paleoceanographic record, but relatively little has been written regarding the origin of the equivalent of the sapropels in the western Mediterranean, the organic-rich layers (ORLs). ORLs are recognized as sediment layers containing enhanced total organic carbon that extend throughout the deep basins of the western Mediterranean and are associated with enhanced total barium concentration and a reduced diversity (dysoxic but not anoxic) benthic foraminiferal assemblage. Consequently, it has been suggested that ORLs represent periods of enhanced productivity coupled with reduced deep ventilation, presumably related to increased continental runoff, in close...

A dynamic model for generating small-scale heterogeneities in ocean floor basalts
Provedor de dados: 5
Autores: Bideau, Daniel; Hekinian, Roger.
Small-scale distribution of basaltic compositions along the mid-ocean ridge crests suggests that the magmatic processes are sensitive to spatial and temporal fluctuations related to proximity of ridge hot spots, changes in spreading rate, thermal boundary effects associated with ridge offsets, off-axis volcanoes and ridge propagators, and variations in magma supply through time. A detailed sampling of the East Pacific Rise (EPR) axis, near 13 degrees N, revealed that complex basalt compositional variations unrelated to morphology and structure occur both on the ridge axis and on nearby off-axis seamounts. This small-scale heterogeneity is attributed to successive magmatic cycles separated by periods of quiescence (amagmatic phases) where each cycle...

A dynamic model of the Bay of Biscay pelagic fleet simulating fishing trip choice: the response to the closure of the European anchovy (Engraulis encrasicolus) fishery in 2005
Provedor de dados: 5
Autores: Vermard, Youen; Marchal, Paul; Mahevas, Stephanie; Thebaud, Olivier.
The scope of this paper is to describe, evaluate, and forecast fishing trip choices of the Bay of Biscay pelagic fleet using random utility modeling (RUM). First, alternative fishing trip choices of this fleet were identified using multivariate statistical methods based on species landings weighted by value and defined as distinct fishing activity or fisheries (termed metiers). A RUM was specified, which included trip components as attributes during the period 20012004 ( a lagged percentage of the value per unit of effort of the main species caught, total value per unit of effort, and inertia in terms of changes from one metier to another). For the main metiers, the proportion of correct effort allocation is 90% during the calibration period of 2001-2004....

The Vibrio splendidus clade has previously been associated with epidemic outbreaks of various aquatic animals, as in the case of the cupped oyster, Crassostrea gigas. To investigate whether involved strains could present a clonal origin and to identify possible alternative background carriage animals or zooplankton, a large epidemiological survey was conducted on isolates of the splendidus clade. For this purpose, Vibrio strains were isolated from various samples including oysters, mussels, sediments, zooplankton, and sea water on the basis of a North/South gradient of the European sea water zone (Ireland, The Netherlands, France, Italy, and Spain). A total of 435 isolates were successfully associated to the V. splendidus clade using real time polymerase...

A evaluation and interpretation of czcs-derived patterns on the adriatic shelf
Provedor de dados: 5
Autores: Sturm, B; Kuzmic, M; Orlic, M.
The aim of the present paper is to investigate further the previously observed dichotomy in the Adriatic waters influenced by the Po river. To that end, an existing algorithm for pigment concentration retrieval has been improved and applied to the reprocessing of selected summer 1981 and winter 1981/1982 images of the Adriatic Sea. The sensitivity loss correction procedure has been included in the retrieval algorithm and rendered coherent with the atmospheric correction model. The model was also updated to allow for multiple Rayleigh scattering, and site-specific calibrated for case 2 waters of the Northern Adriatic. Our analysis of the images reinforces the previous finding (Clement et al., 1987) that two types of CZCS-derived patterns can be observed on...

Autores: Rolland, Jean-luc; Medhioub, Walid; Vergnes, Agnes; Abi-khalil, Celina; Savar, Veronique; Abadie, Eric; Masseret, Estelle; Amzil, Zouher; Laabir, Mohamed.
To better understand the effect of Paralytic Shellfish Toxins (PSTs) accumulation in the digestive gland of the Pacific oyster, Crassostrea gigas, we experimentally exposed individual oysters for 48 h to a PSTs producer, the dinoflagellate Alexandrium catenella. In comparison to the effect of the non-toxic Alexandrium tamarense, on the eight apoptotic related genes tested, Bax and BI.1 were significantly upregulated in oysters exposed 48 h to A. catenella. Among the five detoxification related genes tested, the expression of cytochrome P450 (CYP1A) was shown to be correlated with toxin concentration in the digestive gland of oysters exposed to the toxic dinoflagellate. Beside this, we observed a significant increase in ROS production, a decrease in...

A field report on vibrio disease of seabass (Dicentrarchus labrax ) in the South of France
Provedor de dados: 5
Autores: Breuil, Gilles; Haffner, Philippe.
Vibrio anguillarum was isolated from diseased seabass reared in aquatic farms (hatcheries and grow-out farms) located along the French Mediterranean coast. A representative strain (V62) differs from the French V. anguillarum strain (V408) by its ability to grow on a 0% salinity medium. The pathogenicity of the representative strain for sea bass was confirmed by injections and bath challenge. The V62 strain reacted with V. anguillarum antiserum (V408) and 84% of the isolated strains from diseased sea bass agglutinated with anti V62 serum.

A first generation genetic linkage map of the European flat oyster Ostrea edulis (L.) based on AFLP and microsatellite markers
Provedor de dados: 5
Autores: Lallias, Delphine; Beaumont, A.r.; Haley, C.s.; Boudry, Pierre; Heurtebise, Serge; Lapegue, Sylvie.
This study presents the first genetic linkage map for the European flat oyster Ostrea edulis. AFLP and 20 microsatellite markers were genotyped in a three-generation pedigree comprised of 2 grand-parents, 2 parents and 92 progeny. Chi-square goodness of fit tests revealed high segregation distortion, which was significant for 32.8% of markers. Sixteen microsatellites and 235 AFLPs (170 AFLPs type 1:1 and 65 AFLPs type 3:1) were used to build sex-specific linkage maps using CriMap software. The first parental map (P1) consisted of 104 markers grouped in nine linkage groups, spanning 471.2 cM with an average spacing of 4.86 cM. The second parental map (P2) consisted of 117 markers grouped in ten linkage groups (which equals the haploid chromosome number),...

A first genetic linkage map of the blue mussel Mytilus edulis
Provedor de dados: 5
Autores: Lallias, Delphine; Hecquet, Céline; Boudry, Pierre; Lapegue, Sylvie; Beaumont, Andy.
The blue mussel, Mytilus edulis, is widely distributed in the northern hemisphere, from the White Sea to the Atlantic coast of southern France, and is an economically important species (1 million tons per year, FAO, 2002). At present however, little domestication has been achieved with bivalves, in contrast to agricultural crops, livestock and horticultural species like tomatoes, where selection and production is entirely controlled by man. For bivalves, despite their economic importance, no lines with selected characteristics have been taken to the production scale. There is therefore a need to make up for lost time. Our interest in genetic mapping sprang from some results showing a genetic component to some economically important traits like growth and...

A first genetic linkage map of the European flat oyster, Ostrea edulis : towards the identification of Bonamia resistance QTLs
Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Haley, Chris; Heurtebise, Serge; Boudry, Pierre; Beaumont, Andy.
The flat oyster Ostrea edulis is an endemic European oyster species, found on both Atlantic and Mediterranean coasts. Its aquacultural production has dramatically decreased due to two successive diseases caused by the intracellular parasites Marteilia refringens and Bonamia ostreae. Since 1985, Ifremer has undertaken a breeding program to produce oyster families which are tolerant to Bonamia. In this context, the next step is to identify QTLs for resistance to this parasite. A genetic map is therefore being established as a basis for QTL work. The reference family is an F2 family produced by single pair mating of two oysters from the same F1 family. The F1 family was itself produced from a bi-parental cross between a wild oyster and an individual from the...

This preliminary study assessed genotype x diet interaction in late growth of European sea bass (Dicentrarchus labrax) fed with either a fish meal (FM)- or a fish oil (FO)-based diet (M) or an all-plant-based (PB) diet. A total of 550 fish from 224 families were reared together and tagged. DNA was sampled and microsatellites were used to assign parentage. When fish weight was 192 +/- 54 g, two tanks were fed with M (FM: 100%; FO: 100%) and two others with PB (FM: 0% and FO: 0%). Body weight (BW), fork length (FL) and fillet lipid content (CorrFat) were analysed with a linear model and with REML methodology. We observed no significant differences between groups, but a slightly lower (P=0.03) daily growth coefficient in sea bass fed PB than in those fed M....

The removal of chemical species from seawater during the precipitation of authigenic minerals is difficult to constrain but may play a major role in the global biogeochemical cycles of some elements, including silicon (Si) and germanium (Ge). Here, we present Ge/Si, δ74Ge, and supporting chemical data of pore waters and core incubations at three continental margin sites in California and the Gulf of Mexico. We used these data to partition Ge release and uptake by the various allogenic (delivered via sedimentation) and authigenic (formed in situ) phases in these sediments. About half of the pore water Ge (δ74Gepw = 1.3–2.4‰) is supplied by biogenic silica dissolution (δ74Ge ~ 3‰), with the other half contributed by lithogenic particulates (δ74Ge ~ 0.6‰)....

Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last similar to 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record the equatorial Indian Ocean SST was similar to 2.1 degrees C colder during the last glacial maximum as compared to present times. The data further shows that the surface equatorial Indian Ocean was comparatively warmer during isotopic stage 5e than at present (similar to 29.9 vs similar to 28.5 degrees C). Comparison of the equatorial Indian Ocean SST with the Antarctic delta D and Greenland delta(18)O records, shows that the major high-latitude cooling/warming events are also present in the equatorial Indian Ocean SST variation...

Autores: Madhupratap, M; Sawant, S; Gauns, M.
A thick bloom of the marine prymnesiophycean, Phaeocystis globosa was observed in the central Arabian Sea during the summer monsoon period (July-August, 1996). The cells were mostly in colonial form, embedded in gelatinous matrices. The cell diameter was approximately 7 mu m and showed a distinct double feature form. The intensity of the bloom was as high as 3750 x 10(6) cells m(-2) and the carbon content ranged between 33 and 550 mu g L(-1). Almost 90% of the phytoplankton population was composed of P. globosa in the bloom area. Other common forms were chain-forming diatoms like Rhizosolenia spp., Nitzschia spp. and Chaetoreros spp. The photosynthetic pigment chlorophyll a, however did not show any concomitant rise with the bloom intensity probably...

In the Water Framework Directive (European Union) context, a multimetric fish based index is required to assess the ecological status of French estuarine water bodies. A first indicator called ELFI was developed, however similarly to most indicators, the method to combine the core metrics was rather subjective and this indicator does not provide uncertainty assessment. Recently, a Bayesian method to build indicators was developed and appeared relevant to select metrics sensitive to global anthropogenic pressure, to combine them objectively in an index and to provide a measure of uncertainty around the diagnostic. Moreover, the Bayesian framework is especially well adapted to integrate knowledge and information not included in surveys data. In this context,...

A fisheries acoustic multi-frequency indicator to inform on large scale spatial patterns of aquatic pelagic ecosystems
Provedor de dados: 5
Autores: Trenkel, Verena; Berger, Laurent.
Fisheries acoustic instruments provide information on four major groups in aquatic ecosystems: fish with and without swim bladder (tertiary and quaternary consumers), fluidlike zooplankton (secondary consumers) and small gas bearing organisms such as larval fish and phytoplankton (predominantly primary producers). We entertain that this information is useable to describe the spatial structure of organism groups in pelagic ecosystems. The proposal we make is based on a multi-frequency indicator that synthesises in a single metric the shape of the acoustic frequency response of different organism groups, i.e. the dependence of received acoustic backscattered energy on emitting echosounder frequency. We demonstrate the development and interpretation of the...

Background: Flavin-dependent monooxygenases are involved in key biological processes as they catalyze a wide variety of chemo-, regio- and enantioselective oxygenation reactions. Flavoprotein monooxygenases are frequently encountered in micro-organisms, most of which require further functional and biocatalytic assessment. Here we investigated the function of the AbMak1 gene, which encodes a group A flavin monooxygenase in the plant pathogenic fungus Alternaria brassicicola, by generating a deficient mutant and examining its phenotype. Results: Functional analysis indicates that the AbMak1 protein is involved in cell wall biogenesis and influences the melanization process. We documented a significant decrease in melanin content in the Äabmak1 strain...

A fleet of five seafloor observatories, built-up starting from 1995 within the framework of an effective synergy among research institutes and industries, have carried out a series of long-term sea experiments. The observatories are able to operate from shallow waters to deep-sea, down to 4000 m w.d., and to simultaneously monitor a broad spectrum of geophysical and environmental processes, including seismicity, geomagnetic field variations, water temperature, pressure, salinity, chemistry, currents, and gas occurrence. Moreover, they can transmit data in (near)-real-time that can be integrated with...

A fleet-metier based approach of the small scale fishing activity in the French West Indies
Provedor de dados: 5
Autores: Guyader, Olivier; Reynal, Lionel; Demaneche, Sebastien; Berthou, Patrick; Daures, Fabienne.
The development of the ecosystemic approach for fisheries supposes to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation. A prerequisite for integrated analysis is the improvement in the knowledge of fleets structure, fleet evolution and allocation of fishing effort in the different fisheries. However, small scale fisheries are often characterized by a lack of knowledge on the vessel fishing activity. This paper first presents a data collection methodology recently applied in the French West (Guadeloupe and Martinique) for the follow up of the whole vessel population. Based on a statistical analysis of these data sets, the paper develops a fleet-metier matrix giving the...

A flow cytometric approach to study intracellular-free Ca2+ in Crassostrea gigas haemocytes
Provedor de dados: 5
Autores: Aton, Emilie; Renault, Tristan; Gagnaire, Beatrice; Thomas Guyon, Hélène; Cognard, C; Imbert, N.
Bivalve haemocytes are essential in defence mechanisms including phagocytosis. They also produce molecules including hydrolytic enzymes and antimicrobial peptides that contribute to pathogen destruction. Although haemocyte activities have been extensively studied, relatively little is known about the intracellular signalling pathways that are evoked during haemocyte activation and especially the role of calcium.   Flow cytometry has been used for the first time to define the effect of cell incubation in haemolymph and artificial sea water (ASW) on Pacific oyster, Crassostrea gigas, haemocytes. Cell viability, enzymatic activities (esterases and amino peptidases), phagocytosis and granulocyte percentage were analysed. Viability and some activities were...

A flow injection-fluorometric method for the determination of ammonium in fresh and saline waters with a view to in situ analyses
Provedor de dados: 5
Autores: Aminot, Alain; Kerouel, Roger; Birot, Dominique.
A version of the orthophthaldialdehyde-fluorescence ammonium determination for flow injection analysis (FIA) is presented here, with a view to its use for in situ, low-power consumption systems, Thus, the reaction temperature was limited to 30 degreesC and FIA was used in stop-Bow mode (3 min stop). The calibration is linear up to 50 mu mol l(-1), but concentrations up to 100 mu mol l(-1) can be measured. Repeatability is around 1% in the range of 0.5-4 mu mol l(-1) and the detection limit is about 0.03 mu mol l(-1) Over the salinity range of 5-35 (seawater practical salinity scale) the salt effect is almost negligible (within +/- 2%); and below salinity of 5 it increases to a maximum of -9% in fresh water compared to seawater. Hydrogen carbonate,...

A flow-through rearing system for ecophysiological studies of Pacific oyster Crassostrea gigas larvae
Provedor de dados: 5
Autores: Rico Villa, Benjamin; Woerther, Patrice; Mingant, Christian; Le Piver, David; Pouvreau, Stephane; Hamon, Michel; Robert, Rene.
While literature is relatively abundant on adult shellfish, ecophysiological studies at the larval stage are scarce because of both technical difficulties and inadequate methodology. A tool dedicated to provide basic information for larval ecophysiology was accordingly developed. Two steps were followed: first a flow-through method of Crassostrea gigas larval culture was perfected during a set of experiments in which rearing systems and larval density were assessed. Then a continuous hydrobiological data recorder was adapted with modifications to comply with our experimental aim. SILO (Système d'Instrumentation des Larves en flux Ouvert) allowed the successive acquisition of hydrobiological parameters in ten 150 l larval tanks in which larvae were reared...

A four-dimensional analysis of the thermal structure in the Gulf of Lion
Provedor de dados: 5
Autores: Gaillard, Fabienne; Desaubies, Yves; Send, Uwe; Schott, Fritz.
The Theoretical and Experimental Tomography in the Sea Experiment (THETIS 1) took place in the Gulf of Lion to observe the evolution of the temperature field and the process of deep convection during the 1991-1992 winter. The temperature measurements consist, of moored sensors, conductivity-temperature-depth and expendable bathythermograph surveys, ana acoustic tomography. Because of this diverse data set and since the field evolves rather fast, the analysis uses a unified framework, based on estimation theory and implementing a Kalman filter. The resolution and the errors associated with the model are systematically estimated. Temperature is a good tracer of water masses. The time-evolving three-dimensional view of the field resulting from the analysis...

A framework for evaluating management plans comprehensively
Provedor de dados: 5
Autores: Trenkel, Verena; Rochet, Marie-joelle; Rice, Jake C.
We present a framework for evaluating fisheries management plans comprehensively, both rebuilding plans and others. The framework includes a first rapid appraisal of the likelihood that the plan will result in management meeting its objectives, and guides subsequent quantitative analyses of potential weaknesses in the proposed plan. The framework includes four steps: (i) evaluating if a set of management objectives, if achieved, would result in a sustainable fishery, (ii) using qualitative analysis of a bio-economic model to evaluate whether the set of stock management tactics might be capable of achieving the specified fisheries objectives, (iii) using empirical criteria derived from the literature to evaluate if other management measures in the plan...

A framework for qualitatively evaluating management plans in a results-based perspective
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Trenkel, Verena; Rice, Jake.
Currently many multi-year management plans are being developed either for rebuilding depleted stocks or for avoiding difficult negotiations when management decisions must be revisited on a regular basis. Management plans are commonly evaluated by intensive model simulations that describe the ecological and economic dynamics, and the management loop. Under the results-based management paradigm, the fishing industry or particular fishing sectors will develop their own management plans, potentially leading to a huge number of plans to be evaluated. Guidelines for evaluating the plans on a qualitative level before launching quantitative evaluations will be essential. Here we propose a framework for evaluating management strategies in a qualitative way. A...

A framework for selecting a suite of indicators for fisheries management
Provedor de dados: 5
Autores: Rice, Jake; Rochet, Marie-joelle.
We develop a framework for the objective selection of a suite of indicators for use in fisheries management. The framework encompasses eight steps, and provides guidance on pitfalls to be avoided at each step. Step I identifies user groups and their needs, featuring the setting of operational objectives, and Step 2 identifies a corresponding list of candidate indicators. Step 3 assigns weights to nine screening criteria for the candidate indicators: concreteness, theoretical basis, public awareness, cost, measurement, historic data, sensitivity, responsiveness, and specificity. Step 4 scores the indicators against the criteria, and Step 5 summarizes the results. Steps 3-5 offer technical aspects on which guidance is provided, including scoring standards...

Video and image data are regularly used in the field of benthic ecology to document biodiversity. However, their use is subject to a number of challenges, principally the identification of taxa within the images without associated physical specimens. The challenge of applying traditional taxonomic keys to the identification of fauna from images has led to the development of personal, group, or institution level reference image catalogues of operational taxonomic units (OTUs) or morphospecies. Lack of standardisation among these reference catalogues has led to problems with observer bias and the inability to combine datasets across studies. In addition, lack of a common reference standard is stifling efforts in the application of artificial intelligence to...

A framework to quantify uncertainties of seafloor backscatter from swath mapping echosounders
Provedor de dados: 5
Autores: Malik, Mashkoor; Lurton, Xavier; Mayer, Larry.
Multibeam echosounders (MBES) have become a widely used acoustic remote sensing tool to map and study the seafloor, providing co-located bathymetry and seafloor backscatter. Although the uncertainty associated with MBES-derived bathymetric data has been studied extensively, the question of backscatter uncertainty has been addressed only minimally and hinders the quantitative use of MBES seafloor backscatter. This paper explores approaches to identifying uncertainty sources associated with MBES-derived backscatter measurements. The major sources of uncertainty are catalogued and the magnitudes of their relative contributions to the backscatter uncertainty budget are evaluated. These major uncertainty sources include seafloor insonified area (1–3 dB),...

A French environmental specimen bank of marine bivalves : archive of trace chemical contamination
Provedor de dados: 5
Autores: Claisse, Didier; Knoery, Joel.
Since 1979, the French Marine Monitoring network (RNO) has been regularly collecting blue mussels and oysters at some 100 characterized sites along the French shore. The bivalves are used as quantitative bio-indicators of coastal chemical contamination. Since 1981, the collected samples have been stabilized and archived in a sample bank. The sample collection is thus a continuously lengthening record of coastal contamination.  Bivalves are collected by the Ifremer coastal laboratories. In order to eliminate their faeces and pseudofaeces, molluscs are depurated for 24 hours in decanted sea water from the sampling area. They are then sized, shucked from their shell and frozen in pools of 20-50 animals. At the Dépt of Biogeochemistry and Ecotoxicology, the...

Autores: Corporeau, Charlotte; Groisillier, Agnes; Jeudy, Alexandra; Barbeyron, Tristan; Fleury, Elodie; Fabioux, Caroline; Czjzek, Mirjam; Huvet, Arnaud.
The transforming growth factor (TGF)-beta superfamily is a group of important growth factors involved in multiple processes such as differentiation, cell proliferation, apoptosis and cellular growth. In the Pacific oyster Crassostrea gigas, the oyster gonadal (og) TGF-beta gene was recently characterized through genome-wide expression profiling of oyster lines selected to be resistant or susceptible to summer mortality. Og TGF-beta appeared specifically expressed in the gonad to reach a maximum when gonads are fully mature, which singularly contrasts with the pleiotropic roles commonly ascribed to most TGF-beta family members. The function of og TGF-beta protein in oysters is unknown, and defining its role remains challenging. In this study, we develop a...

We, members of the Association Francaise d'Halieumetrie, share the conviction that European fisheries have a future. It is time to get off the wrong track. Radical change is required to embark on the path of sustainable development and truly implement the ecosystem approach to fisheries. Today, high fishing pressure is deployed to catch a rare resource, which in return is responsible for the rarity. We must reverse the situation: an abundant resource that affords high catches applying moderate fishing pressure. All management tools and especially all actors must be mobilized. The transition is not simple, and European solidarity must accompany the changes. It is well worth the effort. By reducing fishing pressure, it will be possible in the medium term to...

Autores: Leitao, Alexandra; Thiriot-quievreux, Catherine; Malheiro, Isabel; Boudry, Pierre.
The G-banding technique was performed on chromosomes from gill tissue of three cupped oyster species : Crassostrea gigas, Crassostrea angulata and Crassostrea virginica. Identification of the ten individual chromosome pairs was obtained. Comparative analysis of G-banded karyotypes of the three species showed that their banding patterns generally resembled each other, with chromosome pair 3 being similar in all three species. However, differences from one species to another were also observed. The G-banding pattern highlighted greater similarities between C. gigas and C. angulata than between these two species and C. virginica, thus providing an additional argument for genetic divergence between, these two evolutionary lineages. C. gigas and C. angulata...

Environmental management decisions based upon indicators are the end point of a process involving stakeholders and scientists. These steps should be explicit and follow a chronology. This paper presents a general framework for the design and use of management-oriented indicators, integrating management questions and performance criteria. We first examined the desirable characteristics of indicators aimed at providing decision-support for marine environmental management. Ideally, one should select the indicator that guarantees a safe and unambiguous decision leading to the appropriate measures in terms of regulation, remediation or control. In the present study, indicators are assessed according to two criteria: relevance and effectiveness. Relevance...

A Genome Wide Comparison to Identify Markers to Differentiate the Sex of Larval Stages of Schistosoma haematobium, Schistosoma bovis and their Respective Hybrids
Provedor de dados: 5
Autores: Kincaid-smith, Julien; Boissier, Jerome; Allienne, Jean-francois; Oleaga, Ana; Djuikwo-teukeng, Felicite; Toulza, Eve.
For scientists working on gonochoric organisms, determining sex can be crucial for many biological questions and experimental studies, such as crossbreeding, but it can also be a challenging task, particularly when no sexual dimorphism is visible or cannot be directly observed. In metazoan parasites of the genus Schistosoma responsible for schistosomiasis, sex is genetically determined in the zygote with a female heterogametic ZW/ZZ system. Adult flukes have a pronounced sexual dimorphism, whereas the sexes of the larval stages are morphologically indistinguishable but can be distinguished uniquely by using molecular methods. Therefore, reliable methods are needed to identify the sex of larvae individuals. Here, we present an endpoint PCR-based assay using...

During the Equanaute survey (June 1992), fourteen submersible dives were performed between 4950 and 2250 m water depths across the southern slope of the Cote d'Ivoire-Ghana Marginal Ridge (CIGMR), in the eastern Equatorial Atlantic. The CIGMR, a high-standing topographic marginal ridge along the Cote d'Ivoire-Ghana transform margin, is believed to result from a complex structural evolution due to the specific wrench-related rifting between Western Equatorial Africa and Northeastern Brazil, in Early Cretaceous times. In this paper we report and discuss geological observations made during dives, and sample analyses to resolve the lithology, paleoenvironmental conditions, age and origin of the CIGMR. The data help in better characterizing the different...

A geomagnetic paleointensity stack between 0.8 and 3.0 Ma from equatorial Pacific sediment cores
Provedor de dados: 5
Autores: Yamazaki, T; Oda, H.
We have conducted a paleomagnetic study of six sediment cores taken from the equatorial Pacific, three from the West Caroline Basin and three from the Manihiki Plateau, in order to make a relative paleointensity stack during the Matuyama and late Gauss Chrons. The age of the bottom of the cores ranges from 1.2 to 3.0 Ma. The sediments show little downcore changes in the proxies of magnetic grain size and mineralogy and are hence suitable for estimating relative paleointensity. The age of the cores is controlled by correlating variations in magnetic concentration ( magnetic susceptibility and/or anhysteretic remanent magnetization (ARM)) to target oxygen-isotope (delta(18)O) curves. All cores from the Manihiki Plateau show an upward decrease of the natural...

This study is among the first to examine the genesis of the seafloor and subsurface undulations on the Adriatic continental shelf by integrating stratigraphic information and in situ and laboratory geotechnical measurements. Interpretation of sediment behavior is based on a 32-m-long borehole crossing ( 1) a possible shear plane and ( 2) a silty clay layer at about 20 m below seafloor (mbsf) on which sediment undulations are rooted and could be interpreted as a potential weak layer succession. Our main results in terms of triggering mechanism for the observed undulations show that under an earthquake, liquefaction and/or failure of the silty-clay sediments ( weak layer) leading to deformation of the upper more cohesive sediments is possible only when such...

A Geostatistical Definition of Hotspots for Fish Spatial Distributions
Provedor de dados: 5
Autores: Petitgas, Pierre; Woillez, Mathieu; Doray, Mathieu; Rivoirard, Jacques.
Research surveys at sea are undertaken yearly to monitor the distribution and abundance of fish stocks. In the survey data, a small number of high fish concentration values are often encountered, which denote hotspots of interest. But statistically, they are responsible for important uncertainty in the estimation. Thus understanding their spatial predictability given their surroundings is expected to reduce such uncertainty. Indicator variograms and cross-variograms allow to understand the spatial relationship between values above a cutoff and the rest of the distribution under that cutoff. Using these tools, a “top” cutoff can be evidenced above which values are spatially uncorrelated with their lower surroundings. Spatially, the geometric set...

A geostatistical method for assessing biomass of tuna aggregations around moored fish aggregating devices with star acoustic surveys
Provedor de dados: 5
Autores: Doray, Mathieu; Petitgas, Pierre; Josse, E.
Universal kriging was used to model the spatio-temporal variability in the acoustic density of tuna aggregations recorded during star echosounding surveys around moored fish aggregating devices (FADs) in Martinique (Lesser Antilles). The large-scale deterministic drift in the tuna spatial distribution was modeled using an advection-diffusion equation applied to animal grouping. Residuals from the drift were modeled as a random component with small-scale spatial correlation. An estimation variance formula was derived from this deterministic-statistical mixed model to assess the mean precision of density estimates of daytime tuna aggregation. The mean relative error obtained with our star design for daytime surveys was 24%. The methodology was applied to...

ODP Site 1089 is optimally located in order to monitor the occurrence of maxima in Agulhas heat and salt spillage from the Indian to the Atlantic Ocean. Radiolarian-based paleotemperature transfer functions allowed to reconstruct the climatic history for the last 450 kyr at this location. A warm sea surface temperature anomaly during Marine Isotope Stage (MIS) 10 was recognized and traced to other oceanic records along the surface branch of the global thermolialine (THC) circulation system, and is particularly marked at locations where a strong interaction between oceanic and atmospheric overturning cells and fronts occurs. This anomaly is absent in the Vostok ice core deuterium, and in oceanic records from the Antarctic Zone. However, it is present in the...

Differences, similarities and complementarities between Sea Level Anomalies (SLA) deduced from altimeter measurements and dynamic height anomalies (DHA) calculated from Argo in situ temperature (T) and salinity (S) profiles are globally analyzed. SLA and DHA agree remarkably well and, compared to previous studies, Argo dataset allows an improvement in the coherence between SLA and DHA. Indeed, Argo data provides a much better spatial coverage of all oceans and particularly the Southern Ocean, the use of an Argo mean dynamic height, the use of measured salinity profiles (versus climatological salinity), and the use of a deeper reference level (1000 m versus 700 m). The large influence of Argo salinity observations on the consistency between altimetry and...

Light emerging from natural water bodies and measured by remote sensing radiometers contains information about the local type and concentrations of phytoplankton, non-algal particles and colored dissolved organic matter in the underlying waters. An increase in spectral resolution in forthcoming satellite and airborne remote sensing missions is expected to lead to new or improved capabilities to characterize aquatic ecosystems. Such upcoming missions include NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Mission; the NASA Surface Biology and Geology observable mission; and NASA Airborne Visible/Infrared Imaging Spectrometer – Next Generation (AVIRIS-NG) airborne missions. In anticipation of these missions, we present an organized dataset of...

The use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear how generalizable these relationships are across ecosystems, taxa and spatial scales. To address this gap, we collated 80 datasets from trait-based studies into a global database for metaCommunity Ecology: Species, Traits, Environment and Space; “CESTES”. Each dataset includes four matrices: species community abundances or presences/absences across multiple sites, species trait information, environmental...

A database of 15,617 point measurements of dimethylsulfide (DMS) in surface waters along with lesser amounts of data for aqueous and particulate dimethylsulfoniopropionate concentration, chlorophyll concentration, sea surface salinity and temperature, and wind speed has been assembled. The database was processed to create a series of climatological annual and monthly 1 degrees x1 degrees latitude-longitude squares of data. The results were compared to published fields of geophysical and biological parameters. No significant correlation was found between DMS and these parameters, and no simple algorithm could be found to create monthly fields of sea surface DMS concentration based on these parameters. Instead, an annual map of sea surface DMS was produced...

A growing interest is devoted to global-scale approaches in ecology and evolution that examine patterns and determinants of species diversity and the threats resulting from global change. These analyses obviously require global datasets of species distribution. Freshwater systems house a disproportionately high fraction of the global fish diversity considering the small proportion of the earth's surface that they occupy, and are one of the most threatened habitats on Earth. Here we provide complete species lists for 3119 drainage basins covering more than 80% of the Earth surface using 14953 fish species inhabiting permanently or occasionally freshwater systems. The database results from an extensive survey of native and non-native freshwater fish species...

Phytoplankton identification and abundance data are now commonly feeding plankton distribution databases worldwide. This study is a first attempt to compile the largest possible body of data available from different databases as well as from individual published or unpublished datasets regarding diatom distribution in the world ocean. The data obtained originate from time series studies as well as spatial studies. This effort is supported by the Marine Ecosystem Model Inter-Comparison Project (MAREMIP), which aims at building consistent datasets for the main plankton functional types (PFTs) in order to help validate biogeochemical ocean models by using carbon (C) biomass derived from abundance data. In this study we collected over 293 000 individual...

Autores: Van Sebille, Erik; Wilcox, Chris; Lebreton, Laurent; Maximenko, Nikolai; Hardesty, Britta Denise; Van Franeker, Jan A.; Eriksen, Marcus; Siegel, David; Galgani, Francois; Law, Kara Lavender.
Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they have primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models...

A global mean sea surface temperature dataset for the Last Interglacial (129–116 ka) and contribution of thermal expansion to sea level change
Provedor de dados: 5
Autores: Turney, Chris S. M.; Jones, Richard T.; Mckay, Nicholas P.; Van Sebille, Erik; Thomas, Zoë A.; Hillenbrand, Claus-dieter; Fogwill, Christopher J.
A valuable analogue for assessing Earth's sensitivity to warming is the Last Interglacial (LIG; 129–116 ka), when global temperatures (0 to +2 ∘C) and mean sea level (+6 to 11 m) were higher than today. The direct contribution of warmer conditions to global sea level (thermosteric) is uncertain. We report here a global network of LIG sea surface temperatures (SST) obtained from various published temperature proxies (e.g. faunal and floral plankton assemblages, Mg ∕ Ca ratios of calcareous organisms, and alkenone UK′37). We summarize the current limitations of SST reconstructions for the LIG and the spatial temperature features of a naturally warmer world. Because of local δ18O seawater changes, uncertainty in the age models of marine cores, and differences...

Efforts to conserve biodiversity comprise a patchwork of international goals, national-level plans, and local interventions that, overall, are failing. We discuss the potential utility of applying the mitigation hierarchy, widely used during economic development activities, to all negative human impacts on biodiversity. Evaluating all biodiversity losses and gains through the mitigation hierarchy could help prioritize consideration of conservation goals and drive the empirical evaluation of conservation investments through the explicit consideration of counterfactual trends and ecosystem dynamics across scales. We explore the challenges in using this framework to achieve global conservation goals, including operationalization and monitoring and compliance,...

A global monthly climatology of oceanic total dissolved inorganic carbon: a neural network approach

Autores: Broullon, Daniel; Perez, Iz F; Velo, Anton; Hoppema, Mario; Olsen, Are; Takahashi, Taro; Key, Robert M.; Tanhua, Toste; Magdalena Santana-casiano, J.; Kozyr, Alex.
Anthropogenic emissions of CO2 to the atmosphere have modified the carbon cycle for more than 2 centuries. As the ocean stores most of the carbon on our planet, there is an important task in unraveling the natural and anthropogenic processes that drive the carbon cycle at different spatial and temporal scales. We contribute to this by designing a global monthly climatology of total dissolved inorganic carbon (TCO2), which offers a robust basis in carbon cycle modeling but also for other studies related to this cycle. A feedforward neural network (dubbed NNGv2LDEO) was configured to extract from the Global Ocean Data Analysis Project version 2.2019 (GLODAPv2.2019) and the Lamont-Doherty Earth Observatory (LDEO) datasets the relations between TCO2 and a set...

While our knowledge about the roles of microbes and viruses in the ocean has increased tremendously due to recent advances in genomics and metagenomics, research on marine microbial eukaryotes and zooplankton has benefited much less from these new technologies because of their larger genomes, their enormous diversity, and largely unexplored physiologies. Here, we use a metatranscriptomics approach to capture expressed genes in open ocean Tara Oceans stations across four organismal size fractions. The individual sequence reads cluster into 116 million unigenes representing the largest reference collection of eukaryotic transcripts from any single biome. The catalog is used to unveil functions expressed by eukaryotic marine plankton, and to assess their...

Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits in trophic interactions between sharks found in different habitats. We show that populations of shelf-dwelling sharks derive a substantial proportion of their carbon from regional pelagic sources, but contain individuals that forage within additional...

Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR research has been integral to advancing understanding of plankton dynamics and informing policy and management decisions. We describe how the CPR can contribute to global plankton diversity monitoring, being cost-effective over large scales and providing taxonomically resolved data. At OceanObs09 an integrated network of regional CPR surveys was envisaged and in 2011 the existing surveys formed the Global Alliance of CPR Surveys (GACS). GAGS first focused on strengthening the dataset by identifying and documenting CPR best practices,...

A global wave parameter database for geophysical applications. Part 1: Wave-current-turbulence interaction parameters for the open ocean based on traditional parameterizations
Provedor de dados: 5
Autores: Rascle, N; Ardhuin, Fabrice; Queffeulou, Pierre; Croize-fillon, Denis.
Ocean surface mixing and drift are influenced by the mixed layer depth, buoyancy fluxes and currents below the mixed layer. Drift and mixing are also functions of the surface Stokes drift U, volume Stokes transport T-s, a wave breaking height scale H-swg, and the flux of energy from waves to ocean turbulence Phi(oc). Here we describe a global database of these parameters, estimated from a well-validated numerical wave model, that uses traditional forms of the wave generation and dissipation parameterizations, and covers the years 2003-2007. Compared to previous studies, the present work has the advantage of being consistent with the known physical processes that regulate the wave field and the air-sea fluxes, and also consistent with a very large number of...

A Good Compromise: Rapid and Robust Species Proxies for Inventorying Biodiversity Hotspots Using the Terebridae (Gastropoda: Conoidea)
Provedor de dados: 5
Autores: Modica, Maria Vittoria; Puillandre, Nicolas; Castelin, Magalie; Zhang, Yu; Holford, Mande.
Devising a reproducible approach for species delimitation of hyperdiverse groups is an ongoing challenge in evolutionary biology. Speciation processes combine modes of passive and adaptive trait divergence requiring an integrative taxonomy approach to accurately generate robust species hypotheses. However, in light of the rapid decline of diversity on Earth, complete integrative approaches may not be practical in certain species-rich environments. As an alternative, we applied a two-step strategy combining ABGD (Automated Barcode Gap Discovery) and Klee diagrams, to balance speed and accuracy in producing primary species hypotheses (PSHs). Specifically, an ABGD/Klee approach was used for species delimitation in the Terebridae, a neurotoxin-producing marine...

A Grow-and-Lock Model for the Control of Flagellum Length in Trypanosomes
Provedor de dados: 5
Autores: Bertiaux, Eloise; Morga, Benjamin; Blisnick, Thierry; Rotureau, Brice; Bastin, Philippe.
Several models have been proposed to explain how eukaryotic cells control the length of their cilia and flagella. Here, we investigated this process in the protist Trypanosoma brucei, an excellent model system for cells with stable cilia like photoreceptors or spermatozoa. We show that the total amount of intraflagellar transport material (IFT, the machinery responsible for flagellum construction) increases during flagellum elongation, consistent with constant delivery of precursors and the previously reported linear growth. Reducing the IFT frequency by RNAi knockdown of the IFT kinesin motors slows down the elongation rate and results in the assembly of shorter flagella. These keep on elongating after cell division but fail to reach the normal length....

A growing oceanic carbon uptake: Results from an inversion study of surface pCO(2) data
Provedor de dados: 5
Autores: Majkut, Joseph D.; Sarmiento, J. L.; Rodgers, K. B.
Concerted community efforts have been devoted to producing an authoritative climatology of air-sea CO2 fluxes, but identifying decadal trends in CO2 fluxes has proven to be more challenging. The available surface pCO(2) estimates are too sparse to separate long-term trends from decadal and seasonal variability using simple linear models. We introduce Markov Chain Monte Carlo sampling as a novel technique for estimating the historical pCO(2) at the ocean surface. The result is a plausible history of surface pCO(2) based on available measurements and variability inferred from model simulations. Applying the method to a modern database of pCO(2) data, we find that two thirds of the ocean surface is trending toward increasing uptake of CO2, with a mean (year...

Background. Hemocyanins are respiratory proteins with multiple functions. In diverse crustaceans hemocyanins can release histidine-rich antimicrobial peptides in response to microbial challenge. In penaeid shrimp, strictly antifungal peptides are released from the C-terminus of hemocyanins.  Methods. The three-dimensional structure of the antifungal peptide PvHCt from Litopenaeus vannamei was determined by NMR. Its mechanism of action against the shrimp pathogen Fusarium oxysporum was investigated using immunochemistry, fluorescence and transmission electron microscopy.  Results. PvHCt folded into an amphipathic α-helix in membrane-mimicking media and displayed a random conformation in aqueous environment. In contact with F. oxysporum, PvHCt bound...

A hemocyte gene expression signature correlated with predictive capacity of oysters to survive Vibrio infections
Provedor de dados: 5
Autores: Rosa, Rafael Diego; De Lorgeril, Julien; Tailliez, Patrick; Bruno, Roman; Piquemal, David; Bachere, Evelyne.
Background: The complex balance between environmental and host factors is an important determinant of susceptibility to infection. Disturbances of this equilibrium may result in multifactorial diseases as illustrated by the summer mortality syndrome, a worldwide and complex phenomenon that affects the oysters, Crassostrea gigas. The summer mortality syndrome reveals a physiological intolerance making this oyster species susceptible to diseases. Exploration of genetic basis governing the oyster resistance or susceptibility to infections is thus a major goal for understanding field mortality events. In this context, we used high-throughput genomic approaches to identify genetic traits that may characterize inherent survival capacities in C. gigas. Results:...

A herpes-like virus infects a non-ostreid bivalve species: virus replication in Ruditapes philippinarum larvae
Provedor de dados: 5
Autores: Renault, Tristan; Lipart, Cecile; Arzul, Isabelle.
Sporadic high mortalities were reported in June 1997 among hatchery-reared larval Manila clam Ruditapes philippinarum in a French commercial hatchery. Cellular abnormalities were observed in semi-thin sections in affected animals. Transmission electron microscopy revealed the presence of herpes-like virus particles in larvae. This is the first description of a herpes-like virus infection in larval R. philippinarum, a non-ostreid bivalve species. Virus particles were similar to other herpes-like viruses described from different oyster species with respect to ultrastructure and morphogenesis. Electron microscopic examination also demonstrated cells with condensed chromatin and extensive perinuclear fragmentation of chromatin. Like viruses infecting oysters,...

A hierarchical Bayesian model for embedding larval drift and habitat models in integrated life cycles for exploited fish
Provedor de dados: 5
Autores: Rochette, Sebastien; Le Pape, Olivier; Vigneau, Joel; Rivot, Etienne.
This paper proposes a hierarchical Bayesian framework for modeling the life cycle of marine exploited fish with a spatial perspective. The application was developed for a nursery-dependent fish species, the common sole (Solea solea), on the Eastern Channel population (Western Europe). The approach combined processes of different natures and various sources of observations within an integrated framework for life-cycle modeling: (1) outputs of an individual-based model for larval drift and survival that provided yearly estimates of the dispersion and mortality of eggs and larvae, from spawning grounds to settlement in several coastal nurseries; (2) a habitat suitability model, based on juvenile trawl surveys coupled with a geographic information system, to...

A "high He-4/He-3" mantle material detected under the East Pacific Rise (15 degrees 4 ' N)
Provedor de dados: 5
Autores: Mougel, Berengere; Moreira, Manuel; Agranier, Arnaud.
We investigate in details helium isotope data reported in Mougel et al. (2014) for 14 basaltic samples collected on the East Pacific Rise by submersible (15 degrees 4N) where the ridge interacts with the Mathematician seamounts. Samples locations are separated by only few hundred meters across a 15km along-axis profile. The data reveal a strong geochemical variability that has never been observed at such high spatial resolution for helium isotope compositions. Moreover, they reveal an unusually high He-4/He-3 mantle component also characterized by unradiogenic lead, atypical in oceanic basalts. He-Pb systematics suggests a mixture between a nonradiogenic lead and radiogenic helium pyroxenitic component, recycled from the deep continental lithosphere and...

A high load of non-neutral amino-acid polymorphisms explains high protein diversity despite moderate effective population size in a marine bivalve with sweepstakes reproduction
Provedor de dados: 5
Autores: Harrang, Estelle; Lapegue, Sylvie; Morga, Benjamin; Bierne, Nicolas.
Marine bivalves show among the greatest allozyme diversity ever reported in Eukaryotes, putting them historically at the heart of the neutralist-selectionist controversy on the maintenance of genetic variation. Although it is now acknowledged that this high diversity is most probably a simple consequence of a large population size, convincing support for this explanation would require a rigorous assessment of the silent nucleotide diversity in natural populations of marine bivalves, which has not yet been done. This study investigated DNA sequence polymorphism in a set of 37 nuclear loci in wild samples of the flat oyster Ostrea edulis. Silent diversity was found to be only moderate (0.7%), and there was no departure from demographic equilibrium under the...

A highly unstable Holocene climate in the subpolar North Atlantic: evidence from diatoms
Provedor de dados: 5
Autores: Andersen, C; Koc, N; Moros, M.
A composite record (LO09-14) of three sediment cores from the subpolar North Atlantic (Reykjanes Ridge) was investigated in order to assess surface ocean variability during the last 11 kyr. The core site is today partly under the influence of the Irminger Current (IC), a branch of the North Atlantic Drift continuing northwestward around Iceland. However, it is also proximal to the Sub-Arctic Front (SAF) that may cause extra dynamic hydrographic conditions. We used statistical methods applied to the fossil assemblages of diatoms to reconstruct quantitative sea surface temperatures (SSTs). Our investigations give evidence for different regional signatures of Holocene surface oceanographic changes in the North Atlantic. Core LO09-14 reveal relatively low and...

A high-resolution 44-year atmospheric hindcast for the Mediterranean Basin: contribution to the regional improvement of global reanalysis
Provedor de dados: 5
Autores: Sotillo, M; Ratsimandresy, A; Carretero, J; Bentamy, Abderrahim; Valero, F; Gonzalez Rouco, F.
A 44-year (1958-2001) high-resolution atmospheric hindcast for the whole Mediterranean Basin was performed within the EU-funded Hindcast of Dynamic Processes of the Ocean and Coastal Areas of Europe (HIPOCAS) Project. The long-term hindcasted data set, which comprises several atmospheric parameters at different levels, was produced by means of dynamical downscaling from the NCEP/NCAR global reanalysis using the atmospheric limited area model REMO. The REMO hindcast has been exhaustively validated. On that score, various hindcasted surface parameters, such as 10-m wind field, 2-m temperature and mean sea level pressure, have been compared to satellite data (ERS-1/2 scatterometer) and in-situ measurements from offshore stations. In addition, two ocean models...

A high-resolution modeling study of the Western Iberian Margin mean and seasonal upper ocean circulation
Provedor de dados: 5
Autores: Nolasco, Rita; Pires, Ana; Cordeiro, Nuno; Le Cann, Bernard; Dubert, Jesus.
The mean seasonal hydrography and circulation of the Western Iberian Margin (WIM) are studied by means of a high-resolution configuration of the Regional Oceanic Modeling System. A comparison of 5-year model averages for January and July with climatological datasets shows a general good agreement in the reproduction of the mean water mass properties and hydrographic distribution. We find that there is a prevailing tendency for slope poleward flow at about 80-100 km offshore at all latitudes from the surface to 1,500 m with strong vertical coupling. This northward flow, which is mainly along slope and amounts up to 8-10 cm s(-1), exhibits several mean flow recirculation regions on its way and evidences of an offshore pathway of poleward flow. Transports at...

A high-resolution radiolarian-derived paleotemperature record for the Late Pleistocene-Holocene in the Norwegian Sea
Provedor de dados: 5
Autores: Dolven, Jk; Cortese, G; Bjorklund, Kr.
Polycystine radiolarians are used to reconstruct summer sea surface temperatures (SSSTs) for the Late Pleistocene-Holocene (600-13,400 C-14 years BP) in the Norwegian Sea. At 13,200 C-14 years BP, the SSST was close to the average Holocene SSST (similar to12degreesC). It then gradually dropped to 7.1degreesC in the Younger Dryas. Near the Younger Dryas-Holocene transition (similar to10,000 C-14 years BP), the SSST increased 5degreesC in about 530 years. Four abrupt cooling events, with temperature drops of up to 2.1degreesC, are recognized during the Holocene: at 9340, 7100 ("8200 calendar years event''), 6400 and 1650 C-14 years BP. Radiolarian SSSTs and the isotopic signal from the GISP2 ice core are strongly coupled, stressing the importance of the...

A high-resolution reconstruction of palaeoceanographic conditions in the glacial Southern Ocean (Scotia Sea and Adelie Land Coast)
Provedor de dados: 5
Autores: Collins, Lewis G.
Antarctic sea-ice is a critical component of the climate system, an enhancer of glacial climate and, as recently hypothesised by modelling studies, a potential driver of the millennial scale climate variability that dominated the last glacial cycle (LGC). Unfortunately a severe lack of glacial sea-ice records from the Southern Ocean has so far prevented the testing of this hypothesis with field data. In this thesis, I present detailed reconstructions of Antarctic sea-ice and ocean conditions derived from diatom assemblages and the first application of highly branched isoprenoid biomarkers to glacial sediments. These sea-ice sensitive proxies were measured in high-resolution, glacial sediment cores from the Scotia Sea (Southwest Atlantic, West Antarctica)...

A high-resolution record of Southern Ocean intermediate water radiocarbon over the past 30,000 years
Provedor de dados: 5
Autores: Hines, Sophia K. V.; Southon, John R.; Adkins, Jess F.
The circulation of intermediate waters plays an important role in global heat and carbon transport in the ocean and changes in their distribution are closely tied to glacial-interglacial climate change. Coupled radiocarbon and U/Th measurements on deep-sea Desmophyllum dianthus corals allow for the reconstruction of past intermediate water ventilation. We present a high-resolution time series of Antarctic Intermediate Water radiocarbon from 44 corals spanning 30 ka through the start of the Holocene, encompassing the transition into the Last Glacial Maximum (LGM) and the last deglaciation. Corals were collected south of Tasmania from water depths between 1430 and 1950 m with 80% of them between 1500 and 1700 m, giving us a continuous record from a narrow...

A high-resolution study of Holocene paleoclimatic and paleoceanographic changes in the Nordic Seas
Provedor de dados: 5
Autores: Risebrobakken, B; Jansen, E; Andersson, C; Mjelde, E; Hevroy, K.
High-resolution records from IMAGES core MD95-2011 in the eastern Norwegian Sea provide evidence for relatively large- and small-scale high-latitude climate variability throughout the Holocene. During the early and mid-Holocene a situation possibly driven by consistent stronger westerlies increased the eastward influence of Arctic intermediate and near-surface waters. For the late Holocene a relaxation of the atmospheric forcing resulted in increased influence of Atlantic water. The main changes in Holocene climate show no obvious connection to changing solar irradiance, and spectral analysis reveals no consistent signature for any periodic behavior of Holocene climate at millennial or centennial timescales. There are, however, indications of consistent...

A high-resolution temporal record of environmental changes in the Eastern Caribbean (Guadeloupe) from 40 to 10 ka BP
Provedor de dados: 5
Autores: Royer, Aurelien; Malaize, Bruno; Lecuyer, Christophe; Queffelec, Alain; Charlier, Karine; Caley, Thibaut; Lenoble, Arnaud.
In neotropical regions, fossil bat guano accumulated over time as laminated layers in caves, hence providing a high-resolution temporal record of terrestrial environmental changes. Additionally, cave settings have the property to preserve such organic sediments from processes triggered by winds (deflation, abrasion and sandblasting) and intense rainfall (leaching away). This study reports both stable carbon and nitrogen isotope compositions of frugivorous bat guano deposited in a well-preserved stratigraphic succession of Blanchard Cave on Marie-Galante, Guadeloupe. These isotopic data are discussed with regard to climate changes and its specific impact on Eastern Caribbean vegetation during the Late Pleistocene from 40 to 10 ka cal. BP. Guano delta C-13...

A histological examination of grafting success in pearl oyster Pinctada margaritifera in French Polynesia
Provedor de dados: 5
Autores: Cochennec-laureau, Nathalie; Montagnani, Caroline; Saulnier, Denis; Fougerouse, Angelique; Levy, Peva; Lo, Cedrik.
Pearl oyster grafting is a complex surgical operation that should lead to pearl formation after approximately eighteen months. Although this technique has been used for many years in French Polynesia, the grafting process is still not standardised. While studies have been carried out in order to improve graft performance and yield, these remain highly variable due to post-grafting mortality, nucleus rejection and unreliable pearl quality, all of which constrain pearl farm profitability. The present study uses histological analysis to monitor oysters that either rejected or retained their nuclei. Both groups of oysters are compared in terms of evolution of the graft, which could influence retention, and the development of a pearl sac in cases where grafting...

The ontogenetic development of the gut and accessory organs in large yellow croaker Pseudosciaena crocea was investigated using light microscopy from hatching up to the juvenile stage (40 days post hatch, dph). At 3 dph (mean +/- S.D., 4.1 +/- 0.1 mm total length, L-T), coinciding with the buccopharynx opening, larvae started to feed exogenously, and the gut consisted of a well-developed buccopharynx, a partially-differentiated oesophagus and an intestine divided in three regions (anterior intestine, intermediate intestine and rectum). Yolk reserves were not completely depleted at the onset of exogenous feeding, and a period of mixed nutrition was observed up to 6 dph (4.3 +/- 0.1 mm L-T) when yolk was definitively exhausted.

A HMM-based model to geolocate pelagic fish from high-resolution individual temperature and depth histories: European sea bass as a case study
Provedor de dados: 5
Autores: Woillez, Mathieu; Fablet, Ronan; Tran-thanh Ngo,; Lalire, Maxime; Lazure, Pascal; De Pontual, Helene.
Numerous methods have been developed to geolocate fish from data storage tags. Whereas demersal species have been tracked using tide-driven geolocation models, pelagic species which undertake extensive migrations have been mainly tracked using light-based models. Here, we present a new HMM-based model that infers pelagic fish positions from the sole use of high-resolution temperature and depth histories. A key contribution of our framework lies in model parameter inference (diffusion coefficient and noise parameters with respect to the reference geophysical fields—satellite SST and temperatures derived from the MARS3D hydrodynamic model), which improves model robustness. As a case study, we consider long time series of data storage tags (DSTs) deployed on...

A hybrid zone between Bathymodiolus mussel lineages from eastern Pacific hydrothermal vents
Provedor de dados: 5
Autores: Johnson, Shannon B.; Won, Yong-jin; Harvey, Julio B. J.; Vrijenhoek, Robert C.
Background: The inhabitants of deep-sea hydrothermal vents occupy ephemeral island-like habitats distributed sporadically along tectonic spreading-centers, back-arc basins, and volcanically active seamounts. The majority of vent taxa undergo a pelagic larval phase, and thus varying degrees of geographical subdivision, ranging from no impedance of dispersal to complete isolation, often exist among taxa that span common geomorphological boundaries. Two lineages of Bathymodiolus mussels segregate on either side of the Easter Microplate, a boundary that separates the East Pacific Rise from spreading centers connected to the Pacific-Antarctic Ridge.  Results: A recent sample from the northwest flank of the Easter Microplate contained an admixture of northern...

The properties and circulation of water masses leaving and entering the Atlantic Ocean south of Africa are examined using data from a hydrographic and Lowered acoustic Doppler current profiler section from South Africa to the southern limit of the Antarctic Circumpolar Current (ACC). At the upper levels, the ACC fronts are well determined using either classical water mass definitions or gradient-based criteria. While the locations of the Subantarctic Front (SAF), Polar Front (PF), and Southern ACC Front (SACCF) seem controlled by the neighbouring ridges, that of the Subtropical Front (STF) is much influenced in this region (similar to 10 degrees E) by northwestward propagating Agulhas rings. No large amount of Subantarctic Mode Water (SAMW) is observed,...

Autores: Goswami, Bedanta K.; Weitemeyer, Karen A.; Minshull, Timothy A.; Sinha, Martin C.; Westbrook, Graham; Chabert, Anne; Henstock, Timothy J.; Ker, Stephan.
We acquired coincident marine controlled-source electromagnetic (CSEM), high-resolution seismic reflection and ocean-bottom seismometer (OBS) data over an active pockmark in the crest of the southern part of the Vestnesa Ridge, to estimate fluid composition within an underlying fluid-migration chimney. Synthetic model studies suggest resistivity obtained from CSEM data can resolve gas or hydrate saturation greater than 5% within the chimney. Acoustic chimneys imaged by seismic reflection data beneath the pockmark and on the ridge flanks, were found to be associated with high-resistivity anomalies (+2-4 m). High-velocity anomalies (+0.3 km/s), within the gas hydrate stability zone (GHSZ) and low-velocity anomalies (-0.2 km/s) underlying the GHSZ, were also...

The main source of time-mean kinetic energy is the wind stress and the main sink is transfer to mean potential energy. The wind forcing thus helps maintain the density structure. Transient motions result from internal instabilities of the Bow rather than seasonal variations of the forcing. Baroclinic instability is found to be an important mechanism in FRAM. The highest values of available potential energy are found in the western boundary regions as well as in the Antarctic Circumpolar Current (ACC) region. All subregions with predominantly zonal flow are found to be baroclinically unstable. The observed deficit of eddy kinetic energy in FRAM...

L'étude historique de l'ostréiculture française monte que cette activité est caractérisée par des périodes de prospérités et de pénurie. Des épizooties ont été à l'origine de ces alternances. A chacune de ces période, on a pu constater des changements d'espèces : Ostrea edulis fut remplacée par Crassostrea angulata, de même celle-ci fut remplacée par Crassostrea gigas dans les années 1970. L'étude de la bibliographie montre que les techniques utilisées pour distinguer des espèces Crassostrea angulata et Crassostrea gigas sont insuffisantes. L'évolution des technologies en matière d'analyses génétiques ouvrent de nouvelles perspectives.

Autores: Wang, Chen; Mouche, Alexis; Tandeo, Pierre; Stopa, Justin; Longépé, Nicolas; Erhard, Guillaume; Foster, Ralph C.; Vandemark, Douglas; Chapron, Bertrand.
The Sentinel‐1 mission is part of the European Copernicus program aiming at providing observations for Land, Marine and Atmosphere Monitoring, Emergency Management, Security and Climate Change. It is a constellation of two (Sentinel‐1 A and B) Synthetic Aperture Radar (SAR) satellites. The SAR wave mode (WV) routinely collects high‐resolution SAR images of the ocean surface during day and night and through clouds. In this study, a subset of more than 37,000 SAR images is labelled corresponding to ten geophysical phenomena, including both oceanic and meteorologic features. These images cover the entire open ocean and are manually selected from Sentinel‐1A WV acquisitions in 2016. For each image, only one prevalent geophysical phenomenon with its prescribed...

A laboratory model system for analysing microbial interactions occurring in anoxic estuarine sediments.
Provedor de dados: 5
Autores: Herbert, R; Keith, S.
Defined mixed populations of Clostridium butyricum, Desulfovibrio desulfuricans and Chromatium vinosum co-existed for long periods when grown in a single stage chemostat with glucose as sole carbon source. The nature and availability of the inorganic nitrogen source exerted a major effect on carbon flow in the experimental system. The data show that both the C. butyricum and D. desulfuricans isolates can utilise NO sub(3) as an e super(-)acceptor with an increase in cell yield. Under these growth conditions the free S super(2-) levels were lower resulting in more stable mixed populations. In addition the data show that the C. butyricum produces more oxidised fermentation end-products (acetate) when NO sub(3) super(-) was available and more reduced products...

Autores: Davies, Pa; Jacobs, Ptga; Mofor, La.
Laboratory modelling experiments have been conducted to simulate the behaviour and stability characteristics of a buoyant boundary current formed by the discharge of river water into a tidal crossflow. Results from parametric studies of conditions typical of the Channel are presented to show: a) the different forms taken by the boundary currents for stable and unstable currents respectively; b) the dependence of the nose velocity and current width of the boundary current upon the driving density difference and the amplitude of the tidal forcing; and c) variation with Burger number Bu of the growth rate and wavelength of the meander-like instabilities. Measurements are also presented to show the spatial and temporal development of the boundary current...

A Lagrangian analysis of the Indian-Atlantic interocean exchange in a regional model - art. no. L14611
Provedor de dados: 5
Autores: Doglioli, Andrea; Veneziani, M; Blanke, Bruno; Speich, Sabrina; Griffa, A.
We present a new numerical Lagrangian technique based on the coupling of transport computation with spin analysis of trajectories. This method was applied to results from a high-resolution numerical model of the oceanic region around South Africa. We estimated an Indian-Atlantic leakage of about 14 Sv. In the western Cape Basin, approximately 30% of this transport is due to trapping eddies with a ratio between cyclones and anticyclones transport of 1.3. These findings are briefly discussed with respect to recent observations of the highly nonlinear regime found in this area of the Cape Basin.

A Lagrangian Method to Isolate the Impacts of Mixed Layer Subduction on the Meridional Overturning Circulation in a Numerical Model
Provedor de dados: 5
Autores: Thomas, Matthew; Treguier, Anne-marie; Blanke, Bruno; Deshayes, Julie; Voldoire, Aurore.
Large differences in the Atlantic meridional overturning circulation (AMOC) exhibited between the available ocean models pose problems as to how they can be interpreted for climate policy. A novel Lagrangian methodology has been developed for use with ocean models that enables a decomposition of the AMOC according to its source waters of subduction from the mixed layer of different geographical regions. The method is described here and used to decompose the AMOC of the Centre National de Recherches Météorologiques (CNRM) ocean model, which is approximately 4.5 Sv (1 Sv = 106 m3 s−1) too weak at 26°N, compared to observations. Contributions from mixed layer subduction to the peak AMOC at 26°N in the model are dominated by the Labrador Sea, which contributes...

A Lagrangian numerical investigation of the origins and fates of the salinity maximum water in the Atlantic
Provedor de dados: 5
Autores: Blanke, Bruno; Arhan, Michel; Lazar, A; Prevost, Gwenaelle.
The origins and fates of the Atlantic salinity maximum water (SMW), formed through excess evaporation in the tropics and subtropics of both hemispheres, are studied using monthly mean outputs of a numerical simulation of the world ocean climatological circulation. After defining formation domains from the surface salinity field and the vertical stratification, a Lagrangian technique is used to estimate the formation rates and main pathways in each hemisphere and the role of this water in the framework of the warm water return flow of the meridional overturning cell. Formation rates around 9 and 11 Sv are found in the Southern and Northern Hemispheres, respectively. While the export of the southern SMW from its formation area is realized by the western...

A landscape genetic analysis of important agricultural pest species in Tunisia: The whitefly Bemisia tabaci
Provedor de dados: 5
Autores: Ben Abdelkrim, Ahmed; Hattab, Tarek; Fakhfakh, Hatem; Belkadhi, Mohamed Sadok; Gorsane, Faten.
Combining landscape ecology and genetics provides an excellent framework to appreciate pest population dynamics and dispersal. The genetic architectures of many species are always shaped by environmental constraints. Because little is known about the ecological and genetic traits of Tunisian whitefly populations, the main objective of this work is to highlight patterns of biodiversity, genetic structure and migration routes of this pest. We used nuclear microsatellite loci to analyze B. tabaci populations collected from various agricultural areas across the country and we determine their biotype status. Molecular data were subsequently interpreted in an ecological context supplied from a species distribution model to infer habitat suitability and hereafter...

A large waterborne outbreak of infection that occurred during August 2000 in a local community in France was investigated initially via a rapid survey of visits to local physicians. A retrospective cohort study was then conducted on a random cluster sample of residents. Of 709 residents interviewed, 202 (28.5%) were definite cases (at least three liquid stools/day or vomiting) and 62 (8.7%) were probable cases (less than three liquid stools/day or abdominal pain). Those who had drunk tap water had a three-fold increased risk for illness (95% CI 2.4-4.0). The risk increased with the amount of water consumed (chi-square trend: p &lt; 0.0001). Bacteriological analyses of stools were performed for 35 patients and virological analyses for 24 patients....

Planetary formation models show that terrestrial planets are formed by the accretion of tens of Moon-to Mars-sized planetary embryos through energetic giant impacts. However, relics of these large proto-planets are yet to be found. Ureilites are one of the main families of achondritic meteorites and their parent body is believed to have been catastrophically disrupted by an impact during the first 10 million years of the solar system. Here we studied a section of the Almahata Sitta ureilite using transmission electron microscopy, where large diamonds were formed at high pressure inside the parent body. We discovered chromite, phosphate, and (Fe, Ni)-sulfide inclusions embedded in diamond. The composition and morphology of the inclusions can only be...

A large scale study of trace metal contamination (Hg, Cd, Pb and Ni) by means of caged mussels Mytilus galloprovincialis was undertaken along the coastal waters of the Western Mediterranean Sea within the context of the MYTILOS project. Individual mussels from an homogeneous population (shell size 50 +/- 5 mm) obtained from an aquaculture farm were consecutively caged and deployed at 123 sites located in the Alboran, North-Western, South-Western and Tyrrhenian sub-basins for 12 weeks (April-July) in 2004, 2005 and 2006. After cage recoveries, both the metal content in the whole mussel tissue and the allometric parameters were measured. Statistical analysis of the datasets showed significant differences in concentrations between sub-basins for some metals...

A 4-year bacteriological survey (2003-2007) of four molluscs cultivated in France and faced with mortality episodes was performed by the French shellfish pathology network. The more abundant bacteria isolated during 92 mortality episodes, occurring mainly in Pacific oyster Crassostrea gigas, were identified by genotyping methods. It allowed us both to confirm the representativeness of Vibrio splendidus and Vibrio aestuarianus bacterial strains and to identify both a large number of Vibrio harveyi-related strains mainly detected during 2007 oyster mortality outbreaks and to a lesser extent bacterial strains identified as Shewanella colwelliana.

The global high resolution monitoring and forecasting system PSY4 at Mercator Océan, initialized in October 2006, has achieved 11 years of global ocean state estimation. Based on the NEMO global 1/12° configuration, PSY4 includes data assimilation of satellite and multi-instrument in situ observations. In parallel to this monitoring system, a twin-free simulation (with no assimilation) has been performed for the period 2007-2015. In this study, monthly-averaged fields of both ocean state estimates are compared with observation products for the period 2007-2015, to examine the consistency of PSY4 fields with related observations for representing large-scale variability and to provide a baseline that is mainly focused on in situ comparisons for...

A late Paleoproterozoic (1.74 Ga) deep‐sea, low‐temperature, iron‐oxidizing microbial hydrothermal vent community from Arizona, USA
Provedor de dados: 5

Modern marine hydrothermal vents occur in a wide variety of tectonic settings and are characterized by seafloor emission of fluids rich in dissolved chemicals and rapid mineral precipitation. Some hydrothermal systems vent only low‐temperature Fe‐rich fluids, which precipitate deposits dominated by iron oxyhydroxides, in places together with Mn‐oxyhydroxides and amorphous silica. While a proportion of this mineralization is abiogenic, most is the result of the metabolic activities of benthic, Fe‐oxidizing bacteria (FeOB), principally belonging to the Zetaproteobacteria. These micro‐organisms secrete micrometer‐scale stalks, sheaths, and tubes with a variety of morphologies, composed largely of ferrihydrite that act as sacrificial structures, preventing...

A late Quaternary planktonic foraminiferal oxygen isotope record of the Banda Sea: Chronostratigraphy, orbital forcing, and paleoceanographic implications
Provedor de dados: 5
Autores: Chen, Chih-wei; Wei, Kuo-yen; Mii, Horng-sheng; Yang, Tien-nan.
A detailed oxygen isotope time-scale based on planktonic foraminifera Globigerinoides sacculifer at site MD012380 in the Banda Sea was established for the past 820 kyrs by correlating the record to the astronomically tuned benthic oxygen isotope chronology of MD972143. Ages for marine isotope stratigraphic (MIS) events from 2.0 back to 21.1 were designated for this western tropical Pacific record. Spectral analysis of the 6180 time-series reveals distinct periodicities of 100, 41, and 23 kyrs, indicating strong orbital forcing, yet the power of each band varies through time. The time-series of three other paleo-proxies, namely, coarse fraction (CF), lightness of sediments and delta C-13 of Globigerinoides saccidifer, were subjected to cross-spectral...

A Late Quaternary record of highstand shedding from an isolated carbonate platform (Juan de Nova, southern Indian Ocean)
Provedor de dados: 5
Autores: Counts, John; Jorry, Stephan; Vazquez Riveiros, Natalia; Jouet, Gwenael; Giraudeau, Jacques; Cheron, Sandrine; Boissier, Audrey; Miramontes, Elda.
A 27 m core collected on the seafloor near Juan de Nova island at 1909 m depth in the SW Indian Ocean preserves a high‐resolution record of carbonate sediment export to the deep sea over the past 1 Myr. Core chronology was established using calcareous nannofossil biostratigraphy and benthic foraminiferal δ18O. Throughout the core, preserved highstand intervals (MIS 1, 5, 7, 9, 11, 13, 15, 23 and 25) are marked by an increase in the aragonite content within the sediment. Aragonite is likely sourced from the nearby Juan de Nova carbonate platform ~10 km to the south, and is interpreted to result from flooding of the platform top. Platform inundation allows carbonate muds to be winnowed from their original shallow‐water environment of deposition, suspended in...

Autores: Loftus, E.; Sealy, J.; Leng, M. J.; Lee-thorp, J. A.
The southern Cape coastal region is important for understanding both the behavioural history of modern humans, and regional and global climate dynamics, because it boasts a long archaeological record and occupies a key geographical location near the intersection of two major oceans. The western boundary Agulhas Current, implicated in global heat exchange dynamics, is an important modulator of southern African climates and yet we understand its past behaviour only broadly as the Current itself scours the coastal shelf and marine sediment core records necessarily provide little detail. Numerous archaeological sites from both the late Pleistocene and Holocene provide the opportunity for reconstruction of near shore seasonal SST records, which respond both to...

Cathodoluminescence (CL) microscopy of the foliated calcite shell hinge sections of live-collected oyster Crassostrea gigas collected at seven locations along a latitudinal gradient from the Netherlands in the North Sea to the Atlantic coast of France, revealed variations in luminescence that were attributable to seasonal variations in calcification of the hinge. Photomicrographs of hinge sections and luminescence profiles were analyzed to define a micro-sampling strategy that was adopted to drill the hinge samples to determine their isotopic composition. Reconstructed seasonal seawater temperatures determined from the stable oxygen isotope (delta O-18) composition along growth profiles from 32 oyster shell hinges showed distinct seasonal isotopic cycles...

A latitudinal productivity band in the central North Atlantic over the last 270 kyr: An alkenone perspective
Provedor de dados: 5
Autores: Villanueva, J; Calvo, E; Pelejero, C; Grimalt, Jo; Boelaert, A; Labeyrie, L.
Productivity changes in the central North Atlantic Ocean have been traced by means of the total C-37 alkenone contents along two sediment cores located at 43 degreesN and 37 degreesN. Both alkenone signals revealed the occurrence of discrete productivity events every 23 kyr. Spectral analyses highlight the presence of a dominant 23-kyr periodicity in the alkenone signal, which is highly coherent to the precession index. However, a close comparison revealed small but relevant differences in the timing of several of the productivity events recorded at both locations. These asynchronies suggest that the alkenone maxima do not necessarily reflect a general increase of productivity over the North Atlantic. We propose that the events are related to a latitudinal...

A Limited Effect of Sub-Tropical Typhoons on Phytoplankton Dynamics
Provedor de dados: 5
Autores: Chai, Fei; Wang, Yuntao; Xing, Xiaogang; Yan, Yunwei; Xue, Huijie; Wells, Mark; Boss, Emmanuel.
Typhoons are assumed to stimulate ocean primary production through the upward mixing of nutrients into the surface ocean, based largely on observations of increased surface chlorophyll concentrations following the passage of typhoons. This surface chlorophyll enhancement, seen on occasion by satellites, more often is undetected due to intense cloud coverage. Daily data from a BGC-Argo profiling float revealed the upper-ocean response to Typhoon Trami in the Northwest Pacific Ocean. Temperature and chlorophyll changed rapidly, with a significant drop in sea surface temperature and surge in surface chlorophyll associated with strong vertical mixing, which was only partially captured by satellite observations. However, no net increase in vertically integrated...

A literature review as an aid to identify strategies for mitigating ostreid herpesvirus 1 in Crassostrea gigas hatchery and nursery systems
Provedor de dados: 5
Autores: Rodgers, Chris; Arzul, Isabelle; Carrasco, Noèlia; Furones Nozal, Dolores.
An understanding of husbandry strategies and any associated risk factors is important for designing management control measures that can reduce mortality in Pacific oysters, Crassostrea gigas, caused by ostreid  herpesvirus 1 (OsHV-1). The type of culture facility can be considered in relation to the potential pathways that could lead to the entry of a pathogen and its survival. In addition, the animal host (e.g. age, physiological state,  selective breeding programmes), husbandry procedures (e.g. stocking density), the pathogen itself (e.g. pathogenicity, virulence) and environmental effects (e.g. temperature) represent other relevant interconnected factors. However, all these factors provide valuable background information for outlining the mitigation...

A Long Gravity-Piston Corer Developed for Seafloor Gas Hydrate Coring Utilizing an In Situ Pressure-Retained Method
Provedor de dados: 5
Autores: Chen, Jia-wang; Fan, Wei; Bingham, Brian; Chen, Ying; Gu, Lin-yi; Li, Shi-lun.
A corer, which can obtain long in situ pressure-retained sediments of up to 30 m core containing gas hydrates, has been applied in the South China Sea (SCS) dozens of times. The corer presented in this paper is a convenient, efficient and economical long in situ pressure-retained coring and research tool for submarine sediments, that can applied to completely cope with all sediments close to the seafloor ranging from shallow waters to the deep sea depths of 6000 m. This article mainly presents the overall structure, working principles, key pressure-retained components, coring mechanism, sea trials and outlook of the corer. The analyses found that the coring ability was affected by formation characteristics, the outer diameter of the core barrels and inner...

A long term study of bonamiosis in Quiberon bay, France
Provedor de dados: 5
Autores: Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Joly, Jean-pierre; Francois, Cyrille; Berthe, Franck.
Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the...

Provedor de dados: 5
Autores: Reverdin, Gilles; Gascard, Jean-claude; Le Cann, Bernard; Prieur, Loic; Assenbaum, Michel; Lherminier, Pascale.
An anticyclonic mode water vortex and its environment were investigated from November 2000 to September 2001 in the northeast Atlantic (near 43.5 degrees N, 15 degrees-19 degrees W) with neutrally buoyant drifting floats, moored current meters, satellite altimetric sea surface height, and several hydrological surveys and sections. These observations reveal a coherent inner core (similar to 0 km in diameter) made of very oxygenated northeast Atlantic central waters (11 degrees-12.7 degrees C and 35.5-35.7 on the 1978 practical salinity scale) from 150 m down to about 750-m depth. The core presents high relative vorticity (up to approximately -0.5 times the Coriolis frequency f) within at least 10 km of its center, near 400-700 m. Peak velocity along the...

A low delta7 Li lower crustal component: Evidence from an alkalic intraplate volcanic series (Chaine des Puys, French Massif Central)
Provedor de dados: 5
Autores: Hamelin, Cedric; Seitz, Hans-michael; Barrat, Jean-alix; Dosso, Laure; Maury, Rene; Chaussidon, Marc.
The intraplate volcanic suite of the Chaine des Puys (French Massif Central) shows a complete petrologic range, from alkali basalts to trachytes. The significant variations of trace elements and radiogenic isotopes along the series strongly support the occurrence of crustal assimilation associated with fractional crystallization (AFC). The least contaminated basalts are clearly related to a HIMU-type reservoir (Pb-206/Pb-204&gt;19.6; Sr-87/Sr-86&lt;0.7037; epsilon(Nd)&gt;+4). The behavior of radiogenic isotopes suggests that the most likely crustal contaminants are meta-sediments located in the lower crust. The Li isotopic compositions of the lavas range from high delta Li-7 (&gt; + 7 parts per thousand) in basalts to lighter values in more evolved lavas...

Autores: Kedzierski, Mikaël; Falcou-préfol, Mathilde; Kerros, Marie Emmanuelle; Henry, Maryvonne; Pedrotti, Maria Luiza; Bruzaud, Stéphane.
The development of methods to automatically determine the chemical nature of microplastics by FTIR-ATR spectra is an important challenge. A machine learning method, named k-nearest neighbors classification, has been applied on spectra of microplastics collected during Tara Expedition in the Mediterranean Sea (2014). To realize these tests, a learning database composed of 969 microplastic spectra has been created. Results show that the machine learning process is very efficient to identify spectra of classical polymers such as poly(ethylene), but also that the learning database must be enhanced with less common microplastic spectra. Finally, this method has been applied on more than 4000 spectra of unidentified microplastics. The verification protocol...

Autores: Sauger, Carine; Quinquis, Jerome; Kellner, Kristell; Heude-berthelin, Clothilde; Lepoittevin, Mélanie; Elie, Nicolas; Dubroca, Laurent.
The North Sea plaice, Pleuronectes platessa (Linnaeus, 1758), is a commonly studied commercial flatfish with poorly known ovarian histology. The following dataset is a collection of female plaice gonad images and their corresponding histological slides, collected during a complete season of the plaice’s reproduction cycle. Stereology was used to determine the percentage of different structures found throughout the ovaries. Inter-agent calibrations were accomplished in order to harmonize the stereological readings, and were based on a comprehensive reading protocol and histological lexicon that were specifically written for the plaice’s ovaries. The distribution and homogeneity of the different cell types found throughout the ovaries were also evaluated....

Autores: Moussa, M.; Cauvin, E.; Le Piouffle, A.; Lucas, O.; Bidault, Adeline; Paillard, Christine; Benoit, F.; Thuillier, B.; Treilles, M.; Travers, Marie-agnes; Garcia, Celine.
In mollusk aquaculture, a large number of Vibrio species are considered major pathogens. Conventional methods based on DNA amplification and sequencing used to accurately identify Vibrio species are unsuitable for monitoring programs because they are time-consuming and expensive. The aim of this study was, therefore, to develop the MALDI-TOF MS method in order to establish a rapid identification technique for a large panel of Vibrio species. We created the EnviBase containing 120 main spectra projections (MSP) of the Vibrio species that are potentially responsible for mollusk diseases, comprising 25 species: V. aestuarianus, V. cortegadensis, V. tapetis and species belonging to the Coralliilyticus, Harveyi, Mediterranei, and Orientalis clades. Each MSP was...

Autores: Kell, L. T.; Fromentin, Jean-marc.
This paper presents an example of Management Strategy Evaluation (MSE) for Mediterranean and East Atlantic bluefin tuna using the FLR open source framework. Scenarios corresponding to alternative plausible hypotheses about the stock dynamics were used to evaluate alternative management strategies and to test their robustness to implementation error e.g. catch mis-reporting. The strategies evaluated correspond to i) harvest control rule (HCR) based upon F0.1 (a proxy for FMSY ) with an objective of restoring the stock to a level that would “ permit the maximum sustainable catch” and ii) a reduction of fishing mortality on immature fish. The main conclusions were that the F0.1 HCR alone would not result in the recovery of the stock in the next 15 years and...

A marine bacterial adhesion microplate test using the DAPI fluorescent dye: a new method to screen antifouling agents
Provedor de dados: 5
Autores: Leroy, Celine; Delbarre Ladrat, Christine; Ghillebaert, F; Rochet, Marie-joelle; Compere, Chantal; Combes, D.
Aims: To develop a method to screen antifouling agents against marine bacterial adhesion as a sensitive, rapid, quantitative microplate fluorescent test.  Methods and Results: Our experimental method is based on a natural biofilm formed by mono-incubation of the marine bacterium Pseudoalteromonas sp. D41 in sterile natural sea water in a 96 wells polystyrene microplate. The 4'6-diamidino-2-phenylindole (DAPI) dye was used to quantify adhered bacteria in each well. Total measured fluorescence in wells was correlated with the amount of bacteria showing a detection limit of one bacterium per 5 µm2 and quantifying 2 x 107 to 2 x 108 bacteria adhered per cm2. The antifouling properties of three commercial surface active agents and chlorine were tested by this...

Autores: Van, Mai Viet; Phuong, Nguyen Thanh; Dinh, Tran Dac; Villanueva, Ching-maria; Moreau, Jacques.
A mass-balance Ecopath model of coastal areas in the Mekong Delta has been constructed for a quantitative description of the trophic structure of the ecosystem. The model is used to estimate the important biological parameters and relationships among the different ecologically important groups. The model is based on the data collected from bottom trawling. There are 14 functional groups based on 58 species from coastal areas in the Mekong Delta survey such as shrimps, squids, crabs, mackerel, small pelagics, demersal fishes, benthic feeders, predator fishes and trash fish. The biomass value was estimated from catch production and bottom trawling surveys. Results show that the estimated total biomass of exploited resources was 3.99 ton.km-2. The values of...

A mathematical model for the determination of the shape and the tensions of a trawl placed in a uniform current

Autores: Theret, Francois.
The determination of trawls shapes and tensions is a very complex problem. At this time only the static aspect has been considered, the trawl being placed into a uniform current. Three types of difficulties have been met : - Firstly, the hydrodynamic behaviour of the meshes is not well known ; - Secondly, a net is a complete flexible structure with no own shape unless submitted to the action of external forces, but so we are facing an actual " fluid-structure interaction" problem ; - Thirdly, a flexible reticulate structure is made of an anisotropie and discontinus material. ln this paper, the net studied is a trawl for which, the only parameters known are the drawing and the characteristics of the cables which link it to the trawler. The method that we...

A Measurement Quality Factor for Swath Bathymetry Sounders
Provedor de dados: 5
Autores: Lurton, Xavier; Augustin, Jean-marie.
The quality estimation associated with individual soundings measured and computed by swath bathymetry sonars is a paramount issue which is most often imperfectly addressed today by sonar manufacturers. In this paper, a unified definition is proposed for a quality factor usable for all swath bathymetry sonars; the depth-relative error is directly estimated from the signal characteristics used in the sounding computation. The basic algorithms are presented for both phase-difference (oblique incidence) and amplitude (normal incidence) detection, and can be readily implemented in any swath bathymetry system using these detection principles. This approach gives a direct access to the objective bathymetric performance of individual soundings, and hence avoids...

A meta‐analysis of fish behavioural reaction to underwater human presence
Provedor de dados: 5
Autores: Samia, Diogo S. M.; Bessa, Eduardo; Blumstein, Daniel T.; Nunes, José A. C. C.; Azzurro, Ernesto; Morroni, Lorenzo; Sbragaglia, Valerio; Januchowski‐hartley, Fraser A.; Geffroy, Benjamin.
In an increasingly anthropic world, humans have profound impacts on the distribution and behaviour of marine fishes. The increased human presence has modified fishesf antipredator behavioural responses, and consequently flight decisions, as a function of their changed perceptions of risk. Understanding how fish react to human presence can help identify the most vulnerable functional groups/species and estimate impacts caused by human disturbance. Shoal and body size are known to influence fish flight initiation distance (FID; the distance between the predator and prey when the prey begins to escape); however, few studies attempt to test the moderators of these relationships. Here, we present a comprehensive meta]analysis evaluating FID of fish in...

A metadata model for cross-domain marine data management, the SeaDataNet/Geo-Seas experience
Provedor de dados: 5
Autores: Diviacco, P.; Casas Munoz, R.; Sorribas, J.; Loubrieu, Thomas.
Data management in the marine sciences faces the complex issue of addressing contrasting cognitive models across scientific domains, meaning the various representations that different communities build for overlapping areas of interest. Each of these communities constructs an identity on a specific and personal set of inherited backgrounds, practices, and tacit knowledge, which are mirrored in how they understand the targets of their studies. From a practical point of view, this can result in mis-linking observations and usage. This paper reports on the work done within the EU FP7 SeaDataNet project to tackle such problems through an integrated discovery and data access paradigm. It is based on a flexible metadata model that allows researchers to link...

A method for controlled target strength measurements of pelagic fish, with application to European anchovy (     Engraulis encrasicolus     )

Autores: Doray, Mathieu; Berger, Laurent; Le Bouffant, Naig; Coail, Jean-yves; Vacherot, Jean-philippe; De La Bernardie, Xavier; Moriniere, Pierre; Lys, Elisabeth; Schwab, Romain; Petitgas, Pierre.
Measuring fish target strength (TS) in the wild is challenging because: (i) TS varies versus physical (orientation relative to the incident sound wave, size, and depth) and physiological fish attributes (maturity and condition), (ii) the target species and its aforementioned attributes are difficult to assess in near real time, and (iii) in the case of packed fish schools, accepted echoes may originate from multiple unresolved targets. We propose a method for controlled TS measurements of densely packed small pelagic fish during daytime, based on the joint use of a Remotely Operated Towed Vehicle, “EROC”, with a pelagic trawl fitted with a codend opening system, “ENROL”. EROC, equipped with a 70-kHz split-beam echosounder (Simrad EK60) and a low-light...

Investigation of amino acids in hydrothermal systems is of prime importance for the understanding of geochemistry and microbiology of hydrothermal vents and plumes, for carbon and metals global cycles, for metabolism of some hydrothermal microorganisms and for the origin of life issue. Extensive theoretical and experimental work on amino acids behaviour in hydrothermal fluids has been done, conversely only few data exist on natural samples. Because each hydrothermal vent is unique, the more data we collect the better we will be able to address each of these questions. Usually amino acids in hydrothermal fluids have been measured by HPLC-FLD. The chromatographic separation was at least 26 min and up to 135 min and the required derivatization step may be...

Because of the difficulty in resolving the large variability of N2 fixation with current methods which rely on discrete sampling, the development of new methods for high resolution measurements is highly desirable. We present a new method for high-frequency measurements of aquatic N2 fixation by continuous flow-through incubations and spectral monitoring of the acetylene (C2H2, a substrate analog for N2) reduction to ethylene (C2H4). In this method, named “Flow-through incubation Acetylene Reduction Assays by Cavity ring-down laser Absorption Spectros-copy” (FARACAS), dissolved C2H2 is continuously admixed with seawater upstream of a continuous-flow stirred-tank reactor (CFSR) in which C2H2 reduction takes place.

Autores: Le Traon, Pierre-yves.
This brief report addresses the problem of objective analysis of fields with spatially variable mean. Conventional objective analysis is confined to fluctuations, where the larger scale is assumed to be known; this report shows how to use the method described by Davis (1985) to estimate simultaneously a large-scale component and a mesoscale component with an accurate error budget. The extension to multivariate analysis is also discussed. The method is then applied to simulated data; this illustrates its contribution in relation to conventional objective analysis.

A method for reducing uncertainty in estimates of fish-school frequency response using data from multifrequency and multibeam echosounders
Provedor de dados: 5
Autores: Berger, Laurent; Poncelet, Cyrille; Trenkel, Verena.
Fish schools can be insonified simultaneously with multifrequency echosounders (e.g. Simrad EK60s) and a multibeam echosounder (e.g. Simrad ME70). This paper presents a method for combining these data to improve estimates of the relative frequency response r(f) of fish schools. Values of r(f) are now commonly used to classify echoes in fishery surveys. The data from the roll- and pitch-stabilized, high-resolution ME70 are used to correct beam-width effects in the multifrequency EK60 data. First, knowing the exact position and orientation of the transducers and the position of the vessel, the echoes are placed into a common geographic coordinate system. Then, the EK60 data are rejected if they do not include a significant percentage of the fish school...

Heterotrophic bacteria are key players in the biogeochemical cycle of iron (Fe) in the ocean, but the capability of different bacterial groups to access this micronutrient is ignored thus far. The aim of our study was to develop a protocol for the combined application of microautoradiography (MICRO) and catalyzed reporter depositionfluorescence in situ hybridization (CARD-FISH) using the radioisotope 55Fe. Among the different washing solutions tested, Ti-citrate-EDTA was the most efficient for the removal of extracellular 55Fe providing sufficiently low background values. We further demonstrate that the washing of cells with Ti-citrate-EDTA and the fixation with paraformaldehyde or formaldehyde do not induce leakage of intracellular 55Fe. Incubating...

Autores: Pointin, Fabien; Cornou, Anne-sophie; Prod'Homme, Romain; Taupin, Nicolas; Rochet, Marie-joelle.
he Landing Obligation is legislation meant to gradually reduce discards in European fisheries from 2015. Identifying spatial patterns of landings and discards is an important element in mitigating the effects of this legislation on fishing activity. On-board observer data have already been used to address this issue based on models involving statistical assumptions in relation to the non-random spatial distribution of data, which may cause errors in the parameters of interest. An alternative non-model-based mapping method using nested grids is applied to explore the spatial distribution of landings and discards for two French fishing métiers in the Celtic Sea and western English Channel from 2011 to 2016. The grid fineness and the estimate precision are...

We describe in the present study a quick and reliable method based on chlorophyll a fluorescence to assess putative algicidal effect of different microalgal extracts. We couple microalgal production under chemostat cultivation mode to continuously produce a given microalgae species (e.g. Dunaliella salina in this study) at a stable physiological state to ease comparison between extracts tested; with a non-destructive method based on chlorophyll a fluorescence. Pulse amplitude modulated (PAM) fluorometry was used to assess over time the effect of different microalgal crude extracts on the efficiency of the photosystem II (PSII) of a tested microalgae (Dunaliella salina). • Microalgal production at stationary phase in stirred closed photobioreactor (PBR)...

A methodological framework for characterizing fish swimming and escapement behaviors in trawls
Provedor de dados: 5
Autores: Robert, Marianne; Cortay, Aurore; Morfin, Marie; Simon, Julien; Morandeau, Fabien; Deneubourg, Jean Louis; Vincent, Benoit.
Knowledge about fish behavior is crucial to be able to influence the capture process and catch species composition. The rapid expansion of the use of underwater cameras has facilitated unprecedented opportunities for studying the behavior of species interacting with fishing gears in their natural environment. This technological advance would greatly benefit from the parallel development of dedicated methodologies accounting for right-censored observations and variable observation periods between individuals related to instrumental, environmental and behavioral events. In this paper we proposed a methodological framework, based on a parametric Weibull mixture model, to describe the process of escapement attempts through time, test effects of covariates and...

The rapid expansion of the use of passive acoustic telemetry technologies has facilitated unprecedented opportunities for studying the behavior of marine organisms in their natural environment. This technological advance would greatly benefit from the parallel development of dedicated methodologies accounting for the variety of timescales involved in the remote detection of tagged animals related to instrumental, environmental and behavioral events. In this paper we propose a methodological framework for estimating the site fidelity (“residence times”) of acoustic tagged animals at different timescales, based on the survival analysis of continuous residence times recorded at multiple receivers. Our approach is validated through modeling and applied on two...

Despite the large number of species distribution modelling (SDM) applications driven by tracking data, individual information is most of the time neglected and traditional SDM approaches commonly focus on predicting the potential distribution at the species or population‐level. By running classical SDMs (population approach) with mixed models including a random factor to account for the variability attributable to individual (individual approach), we propose an innovative five‐steps framework to predict the potential and individual‐level distributions of mobile species using GPS data collected from green turtles. Pseudo‐absences were randomly generated following an environmentally‐stratified procedure. A negative exponential dispersal kernel was...

Autores: Quemmerais-amice, Frédéric; Barrere, Julien; La Rivière, Marie; Contin, Gabriel; Bailly, Denis.
The implementation of the European integrated marine policy poses many scientific challenges. Among them, the knowledge and understanding of interactions between anthropogenic pressures and ecological components is an important issue, particularly to help define Good Environmental Status, environmental targets and monitoring programs of the Marine Strategy Framework Directive (2008, MSFD). Assessment of cumulative effects of different pressures is a particularly complex issue requiring modeling tools and methods, as well as accurate data sets on human activities, anthropogenic pressures and ecological components. The results of these assessments are also uncertain and highly dependent on the calculation methods and assumptions, as well as on the data sets...

A methodology based on data filtering to identify reference fleets to account for the abundance of fish species: Application to the Striped red mullet (Mullus surmulletus) in the Bay of Biscay
Provedor de dados: 5
Autores: Caill-milly, Nathalie; Lissardy, Muriel; Bru, Noëlle; Dutertre, Marie-adèle; Saguet, Cassandre.
For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and...

An assessment of the reared stocks of the Pacific oyster (Crassostrea gigas ) has been recently conducted on the major French areas of molluscs culture. The methodology proposed included both estimates of densities obtained by subsampling in the field, and aerial photographs which covered the cultivated, intertidal area. The size and the number of samples were designed to reach a precision of 10% on the final assessment in each area. The field work consisted in weighing and counting the oyster in unit areas of 0.5 m2 for the bottom culture or in trays or bags, for the off bottom technique. These results give a better knowledge of the technique evolution and of the general structures in the cultivated areas.

Methylation of mercury (Hg) is the crucial process that controls Hg biomagnification along the aquatic food chains. Aquatic sediments are of particular interest because they constitute an essential reservoir where inorganic divalent Hg (HgII) is methylated. Methylmercury (MeHg) concentrations in sediments mainly result from the balance between methylation and demethylation reactions, two opposite natural processes primarily mediated by aquatic microorganisms. Thus, Hg availability and the activity of methylating microbial communities control the MeHg abundance in sediments. Consistently, some studies have reported a significant positive correlation between MeHg and HgII or total Hg (HgT), taken as a proxy for HgII, in aquatic sediments using...

The European clam, Ruditapes decussatus is a species with a high commercial importance in Portugal and other Southern European countries. Its production is almost exclusively based on natural recruitment, which is subject to high annual fluctuations. Increased knowledge of the natural reproductive cycle of R. decussatus and its molecular mechanisms would be particularly important in providing new highly valuable genomic information for better understanding the regulation of reproduction in this economically important aquaculture species. In this study, the transcriptomic bases of R. decussatus reproduction have been analysed using a custom oligonucleotide microarray representing 51,678 assembled contigs. Microarray analyses were performed in four gonadal...

A microarray-based analysis was performed with the objective of describing genomic features of oocytes and looking for potential markers of oocyte quality in the economically important European clam, Ruditapes decussatus. Oocytes of 25 females from Ria de Aveiro, Western coast of Portugal (40°42′N; 08°40′W) were selected for this study and oocyte quality was estimated by success of D-larval rate under controlled conditions, which appeared to vary from 0 to 95 %. By genome-wide expression profiling with a DNA microarray, 526 probes appeared differentially expressed between two groups representing the largest and smallest value of D larval rates, named good (represented by a mean D-larval yield of 57 ± 22%) and poor (9 ± 5%) quality oocytes.

A microbiological and biogeochemical investigation of the cold seep tubeworm Escarpia southwardae (Annelida: Siboglinidae): Symbiosis and trace element composition of the tube
Provedor de dados: 5
Autores: Duperron, Sebastien; Gaudron, Sylvie M.; Lemaitre, Nolwenn; Bayon, Germain.
Tubeworms within the annelid family Siboglinidae rely on sulfur-oxidizing autotrophic bacterial symbionts for their nutrition, and are among the dominant metazoans occurring at deep-sea hydrocarbon seeps. Contrary to their relatives from hydrothermal vents, sulfide uptake for symbionts occurs within the anoxic subsurface sediment, in the posterior ‘root’ region of the animal. This study reports on an integrated microbiological and geochemical investigation of the cold seep tubeworm Escarpia southwardae collected at the Regab pockmark (Gulf of Guinea). Our aim was to further constrain the links between the animal and its symbiotic bacteria, and their environment. We show that E. southwardae harbors abundant sulfur-oxidizing bacterial symbionts in its...

A microeconomic model of discarding behaviour
Provedor de dados: 5
Autores: Macher, Claire; Guyader, Olivier; Boncoeur, Jean.
This paper proposes a formal analysis of the discarding issue including the sorting labour costs. Empirical evidences from an application to the Nephrops fishery in the Bay of Biscay show that sorting is an important time consuming activity on board and a factor of discarding. However existing literature does not explicitly take into account the sorting activity and mainly focus on quota and catch constraints. The discarding model described in the paper includes sorting as a factor explaining discards. The costs of sorting landings and the time to sort them are included in the approach. The model is developed for one species studied at a tow scale with the assumption that catches are exogenous. It is shown that taking sorting costs into account, discarding...

Autores: Amore, F. O.; Flores, J. A.; Voelker, A. H. L.; Lebreiro, S. M.; Palumbo, E.; Sierro, F. J.
Changes in paleoclimate and paleoproductivity patterns have been identified by analysing, in conjunction with other available proxy data, the coccolithophore assemblages from core MD03-2699, located in the Portuguese margin in the time interval from the Marine Isotope Stage (MIS) 13/14 boundary to MIS 9 (535 to 300 ka). During the Mid-Brunhes event, the assemblages associated with the eccentricity minima are characterised by higher nannoplankton accumulation rate (NAR) values and by the blooming of the opportunistic genus Gephyrocapsa. Changes in coccolithophore abundance are also related to glacial-interglacial cycles. Higher NAR and numbers of coccoliths/g mainly occurred during the interglacial periods, while these values decreased during the glacial...

A mid-Holocene transition in the nitrogen dynamics of the western equatorial Pacific: Evidence of a deepening thermocline?

Autores: Kienast, M.; Lehmann, M. F.; Timmermann, A.; Galbraith, E.; Bolliet, T.; Holboum, A.; Normandeau, C.; Laj, C.
Sedimentary delta(15)N records from the oligotrophic western equatorial Pacific (WEP) off Mindanao show that late Holocene sedimentary delta(15)N is substantially lower than that of the early Holocene, following a gradual &gt;3 parts per thousand decrease that occurred between 7 and 3 kyrs ago. Analyses of modem day nitrate isotope profiles from the same region indicate the sensitivity of the WEP N pools towards (1) the advection of (15)N-enriched nitrate from the Eastern Equatorial Pacific (EEP) by the North Equatorial Current (NEC) and the Mindanao Current in subsurface waters and, (2) at shallow depths, the input of new and (15)N-depleted nitrate through N, fixation. We suggest that the Holocene decrease in sedimentary delta(15)N reflects a diminished...

Autores: Lopezi, Jon; Moreno, Gala; Boyra, Guillermo; Dagorn, Laurent.
Most of the drifting fish aggregating devices (DFADs) used in industrial tropical tuna purse seine fisheries are equipped with satellite linked echosounder buoys, which provide fishing crews with remote, accurate geolocation information and rough estimates of FAD-associated tuna biomass. One of the most common brands of echosounder buoys (SATLINK, Madrid, Spain) is currently calibrated for the target strength of skipjack tuna (Katsuwonus pelamis) and provides biomass data on. that species. Using that brand of echosounder buoy, we developed a new behavior-based approach to provide relative biomass estimates and a remote target classification of fish aggregations at FADs. The model is based on current knowledge of the vertical distribution of the main fish...

A model for predicting the quantities of dissolved inorganic nitrogen released in effluents from a sea bass (Dicentrarchus labrax) recirculating water system
Provedor de dados: 5
Autores: Pagand, Pascal; Blancheton, Jean-paul; Casellas, Claude.
Fish excretions and the transformation of nitrogen by bacteria in the nitrifying biofilter are two of the main sources of dissolved inorganic nitrogen (DIN) in fish farms that use recirculating water systems. In this study, the DIN concentration in an experimental Dicentrarchus labrax aquaculture system was calculated using empirical sub-models for fish growth, ingested food and water replacement. The specific growth rate (SGR) (% day(-1)) and the daily feeding rate (DFR) (% day(-1)) both depend on the average weight, W (g), of the fish: Y = aW(b), where Y may be SGR or DFR, and a and b are empirical constants. The DIN discharge rate, Gamma(N) (% of ingested nitrogen), in the experimental aquaculture system was expressed as a function of increasing...

A model for the generation of nonlinear internal tides in the strait of gibraltar

Autores: Longo, A; Manzo, M; Pierini, S.
A nonlinear, two-layer, rigid-lid model has been solved numerically by means of a generalized Lax-Wendroff finite difference scheme in order to study the generation of internal tides in the Strait of Gibraltar. Preliminary numerical experiments on asymptotically steady-state solutions in the presence of a constant mean flow are used to validate the model: previous laboratory experiments and analytical solutions are indeed accurately reproduced. Periodic solutions representing the internal tides at Gibraltar are then obtained by allowing a semidiurnal barotropic tidal current to interact with an idealized topographic variation modelling the Camarinal sill. Numerical experiments with and without a basic constant mean flow are carried out and a reasonable...

A model for the phenotypic plasticity of North sea herring growth in relation to trophic conditions
Provedor de dados: 5
Autores: Shinn, Yunne-jai; Rochet, Marie-joelle.
An adaptation of the von Bertalanffy growth model is formulated to describe the phenotypic plasticity of fish somatic growth in relation to trophic conditions. The model is developed for the North sea Downs herring (Clupea harengus). II suggests that annual growth variability during 1974-1990 was mainly due to the combined effects of herring abundance and wind-induced turbulence (coincident with the spring stratification of the water column). Springtime turbulences cause reduced and delayed planktonic blooms preceding the annual foraging period of Downs herring. The negative relation observed between herring abundance and growth is hypothesized to be due to intra-specific competition for trophic resources. Incorporated into the calculation of yield per...

The South‐East Madagascar Bloom, one of the most compelling biogeochemical features of the Indian Ocean, occurs sporadically during austral summer in the oligotrophic waters south‐east of Madagascar, where it can cover up to 1% of the global ocean surface area. Its spatial extension and its timing are highly variable. A high‐resolution biophysical model is used to investigate a previous hypothesis that the onset of a particular circulation of the South‐East Madagascar Current advects fresher and nutrient‐rich waters eastward, feeding the bloom. The model is able to reproduce an intermittent phytoplankton bloom with large spatial variability but in the subsurface layers, as well as the presence of an irregular retroflection of the South‐East Madagascar...

A model of fluff layer erosion and subsequent bed erosion in the presence of the bioturbator, Hydrobia ulvae
Provedor de dados: 5
Autores: Orvain, Francis; Le Hir, Pierre; Sauriau, Pierre-guy.
Previous studies have shown that the gastropod Hydrobia ulvae destabilizes the top layers of fine-grained sediments. This process is mediated by the formation of a "biogenic" fluff layer that includes tracks, faecal pellets and mucus. This fluff layer has been shown to be easily resuspended before general bed erosion. In order to examine how fluff layer and bed. erosion interact, flume experiments were performed with fluid sediments of varying water contents. Ten thousand snails were placed and allowed to crawl for 5 h on the sediment surface, and then the resuspended sediment mass was measured in response to step-wise shear stress increases. Two distinct erosion phases were observed: (1) initial resuspension of the fluff layer and (2) the subsequent bed...

A model of sea-foam thickness distribution for passive microwave remote sensing applications
Provedor de dados: 5
Autores: Reul, Nicolas; Chapron, Bertrand.
[1] Foam formations at the sea surface significantly contribute to microwave brightness temperature signatures over the ocean for moderate to high wind speeds. The thickness of foam layers generated by breaking waves follows a specific distribution due to unsteadiness of breaking and the large range of wave scales involved in the phenomenon. Although the effect of a distributed thickness-parameter on the foam-induced microwave brightness temperature may be comparable to or larger than the fractional whitecap coverage, it is not yet included in brightness models. To fill this gap, we develop a dynamical model for the conditional fraction of sea-surface covered by whitecaps with given thickness, as a function of wind speed. It is an integrated function of...

Flume experiments were designed to study how sediment erodibility was modified by the facultative suspension-feeder Scrobicularia plana living at different densities in sediment beds of various degrees of compaction. Two separate erosion phases were identified from the resuspension kinetics: (1) erosion of an unconsolidated surficial layer (i.e. fluff layer) and (2) the subsequent bed erosion. S. plana were found to influence both erosion phases: (1) erosion rates of the fluff layer were controlled by bioturbation activities, the extents of which were influenced by bivalve density and the degree of compaction of the sediments, and (2) critical thresholds of the subsequent bed erosion decreased as clam density increased, likely due to depressions in the...

A model perspective on the dynamics of the shadow zone of the eastern tropical North Atlantic - Part 1: the poleward slope currents along West Africa
Provedor de dados: 5
Autores: Kounta, Lala; Capet, Xavier; Jouanno, Julien; Kolodziejczyk, Nicolas; Sow, Bamol; Gaye, Amadou Thierno.
The West African seaboard is one of the upwelling sectors that has received the least attention, and in situ observations relevant to its dynamics are particularly scarce. The current system in this sector is not well known and understood, e.g., in terms of seasonal variability, across-shore structure, and forcing processes. This knowledge gap is addressed in two studies that analyze the mean seasonal cycle of an eddy-permitting numerical simulation of the tropical Atlantic. Part 1 is concerned with the circulation over the West African continental slope at the southernmost reach of the Canary Current system, between similar to 8 and 20 degrees N. The focus is on the depth range most directly implicated in the wind-driven circulation (offshore and coastal...

A model study of the seasonal and long-term North Atlantic surface pCO(2) variability
Provedor de dados: 5
Autores: Tjiputra, J. F.; Olsen, A.; Assmann, K.; Pfeil, Benjamin; Heinze, C.
A coupled biogeochemical-physical ocean model is used to study the seasonal and long-term variations of surface pCO(2) in the North Atlantic Ocean. The model agrees well with recent underway pCO(2) observations from the Surface Ocean CO2 Atlas (SOCAT) in various locations in the North Atlantic. Some of the distinct seasonal cycles observed in different parts of the North Atlantic are well reproduced by the model. In most regions except the subpolar domain, recent observed trends in pCO(2) and air-sea carbon fluxes are also simulated by the model. Over the longer period between 1960-2008, the primary mode of surface pCO(2) variability is dominated by the increasing trend associated with the invasion of anthropogenic CO2 into the ocean. We show that the...

The eastern Baltic cod stock collapsed as a consequence of climate-driven adverse hydrographic conditions and over fishing and has remained at historically low levels. Spatio-temporal fishing closures [Marine Protected Areas (MPAs)] have been implemented since 1995, to protect and restore the spawning stock. However, no signs of recovery have been observed yet, either suggesting that MPAs are an inappropriate management measure or pointing towards suboptimal closure design. We used the spatially explicit fishery simulation model ISIS-Fish to evaluate proposed and implemented fishery closures, combining an age-structured population module with a multifleet exploitation module and a management module in a single model environment. The model is parameterized...

A model-based study of ice and freshwater transport variability along both sides of Greenland
Provedor de dados: 5
Autores: Lique, Camille; Treguier, Anne-marie; Scheinert, Markus; Penduff, Thierry.
We investigate some aspects of the variability of the Arctic freshwater content during the 1965-2002 period using the DRAKKAR eddy admitting global ocean/sea-ice model (12 km resolution in the Arctic). A comparison with recent mooring sections shows that the model realistically represents the major advective exchanges with the Arctic basin, through Bering, Fram and Davis Straits, and the Barents Sea. This allows the separate contributions of the inflows and outflows across each section to be quantified. In the model, the Arctic freshwater content variability is explained by the sea-ice flux at Fram and the combined variations of ocean freshwater inflow (at Bering) and outflow (at Fram and Davis). At all routes, except trough Fram Strait, the freshwater...

A model-data comparison of the Holocene global sea surface temperature evolution
Provedor de dados: 5
Autores: Lohmann, G.; Pfeiffer, M.; Laepple, T.; Leduc, G.; Kim, J-h.
We compare the ocean temperature evolution of the Holocene as simulated by climate models and reconstructed from marine temperature proxies. We use transient simulations from a coupled atmosphere-ocean general circulation model, as well as an ensemble of time slice simulations from the Paleoclimate Modelling Intercomparison Project. The general pattern of sea surface temperature (SST) in the models shows a high-latitude cooling and a low-latitude warming. The proxy dataset comprises a global compilation of marine alkenone- and Mg/Ca-derived SST estimates. Independently of the choice of the climate model, we observe significant mismatches between modelled and estimated SST amplitudes in the trends for the last 6000 yr. Alkenone-based SST records show a...

A modeling study of processes controlling the Bay of Bengal sea surface salinity interannual variability
Provedor de dados: 5
Autores: Akhil, V. P.; Lengaigne, M.; Vialard, J.; Durand, F.; Keerthi, M. G.; Chaitanya, A. V. S.; Papa, F.; Gopalakrishna, V. V.; De Boyer Montegut, Clement.
Recent observational studies provided preliminary insights on the interannual variability of Bay of Bengal (BoB) Sea Surface Salinity (SSS), but are limited by the poor data coverage. Here, we describe the BoB interannual SSS variability and its driving processes from a regional eddy-permitting ocean general circulation model forced by interannually varying air-sea fluxes and altimeter-derived discharges of major rivers over the past two decades. Simulated interannual SSS variations compare favorably with both in situ and satellite data and are largest in boreal fall in three regions: the northern BoB, the coastal region off east India, and the Andaman Sea. In the northern BoB, these variations are independent from those in other regions and mostly driven...

A modeling study of the processes of surface salinity seasonal cycle in the Bay of Bengal
Provedor de dados: 5
Autores: Akhil, V. P.; Durand, Fabien; Lengaigne, Matthieu; Vialard, Jerome; Keerthi, M. G.; Gopalakrishna, V. V.; Deltel, Charles; Papa, Fabrice; De Boyer Montegut, Clement.
In response to the Indian Monsoon freshwater forcing, the Bay of Bengal exhibits a very strong seasonal cycle in sea surface salinity (SSS), especially near the mouths of the Ganges-Brahmaputra and along the east coast of India. In this paper, we use an eddy-permitting (∼25 km resolution) regional ocean general circulation model simulation to quantify the processes responsible for this SSS seasonal cycle. Despite the absence of relaxation toward observations, the model reproduces the main features of the observed SSS seasonal cycle, with freshest water in the northeastern Bay, particularly during and after the monsoon. The model also displays an intense and shallow freshening signal in a narrow (∼100 km wide) strip that hugs the east coast of India, from...

A modelling study of the respective role of hydrodynamic processes and larval mortality on larval dispersal and recruitment of benthic invertebrates: example of Pectinaria koreni (Annelida : Polychaeta) in the Bay of Seine (English Channel)
Provedor de dados: 5
Autores: Ellien, C; Thiebaut, E; Dumas, Franck; Salomon, Jean-claude; Nival, Paul.
The dispersal of Pectinaria koreni larvae released from the eastern Bay of Seine (English Channel) was studied using a two-dimensional hydrodynamic model which integrates tides, wind-driven currents and eddy diffusion, in order to examine the influence of environmental forcing and mortality on larval population dynamics. A broad agreement between predicted larval dispersal for two spawning events observed in 1987 and field data suggests that numerical modelling may be useful to analyse processes involved in the transport and the dynamics of larval populations. Larval mortality may be as important as hydrodynamic processes on larval losses for the adult population. Tides and eddy diffusion had some effects on larval dispersal, but wind forcing and the...

A modelling study of the thermohaline circulation of the Mediterranean Sea: Water formation and dispersal
Provedor de dados: 5
Autores: Haines, K; Wu, Pl.
A model of the whole Mediterranean sea at 0.25 degrees x 0.25 degrees resolution has been run for ten years with a mean seasonal cycle of forcing using NMC winds and a relaxation to NODC surface temperature and salinity. The winter season water formation and dispersal in the model thermocline has been studied using isopycnal diagnostics and potential vorticity as a water mass tracer. In the eastern basin Levantine Intermediate Water (LIW) is formed in the cyclonic Rhodes gyre and moves west in a continuous mass, accumulating and mixing in the centre of the Northern Ionian. The LIW spreading path is identified both from the high salinity and low potential vorticity values on the 28.8 isopycnal surface. Some LIW then spreads west and south towards Sicily,...

A moderate melting model for the Voring margin (Norway) based on structural observations and a thermo-kinematical modelling: Implication for the meaning of the lower crustal bodies
Provedor de dados: 5
Autores: Gernigon, Laurent; Lucazeau, Francis; Brigaud, Frederic; Ringenbach, Jean-claude; Planke, Sverre; Le Gall, Bernard.
High P-wave velocities (7.1-7.8 km/s) lower crustal bodies (LCBs) imaged along volcanic margins are commonly interpreted as plume and break-up-related thick mafic underplating. This interpretation is partly challenged in this paper based on new seismic observations and modelling of the outer Voring Basin (Norway). An exceptional strong amplitude reflection, the T Reflection, is particularly well defined below the North Gjallar Ridge (NGR) between 7 and 8 s TWT. The T Reflection is located near the volcanic lava flows emplaced during the NE Atlantic breakup (similar to 55-54 Ma ago) and coincides with the top of the LCB, forming a mid-crustal dome. Based on structural and temporal relationships, we show that the dome clearly influences the structural...

Autores: Hamard, Alice; Mazurais, David; Boudry, Gaelle; Le Huerou-luron, Isabelle; Seve, Bernard; Le Floc'H, Nathalie.
High dietary threonine extraction by the digestive tract suggests that threonine contributes to maintain gut physiology. In the present study, we evaluated the impact of a low (6.5 g of threonine/kg diet; LT group) or a control well-balanced threonine diet (9.3 g of threonine/kg diet; C group) given to piglets for 2 weeks on ileal permeability and Na+-dependant glucose absorption capacity in Ussing chambers. The paracellular permeability was significantly increased in the ileum of LT compared to C piglets (P=.017). The Na+-dependent glucose absorption capacity showed a nonsignificant increase in the LT piglets. In addition, we analysed ileal gene expression profiles in the LT and C groups using porcine multitissue cDNA microarrays. Compared to the C...

A modified Arcan test to analyze the behavior of composites and their assemblies under out-of-plane loadings
Provedor de dados: 5
Autores: Cognard, J. Y.; Sohier, L.; Davies, Peter.
Composite materials are a key element in weight reduction strategies, so the analysis of the mechanical behavior of assemblies of composite modules is of great importance. Failure initiation in bonded assemblies involving composites is often associated with crack initiation in the adhesive or delamination of the composite plies close to the adhesive joint, caused by interlaminar or through-thickness stresses. Thus, the analysis of the behavior of composites and their assemblies under out-of-plane loadings is necessary in order to optimize such structures. However, few experimental devices are proposed in the literature and they often require thick composite specimens which are not representative of most industrial applications. This paper describes the use...

A molecular phylogenetic framework for the Ergalataxinae (Neogastropoda: Muricidae)
Provedor de dados: 5
Autores: Claremont, Martine; Houart, Roland; Williams, Suzanne T.; Reid, David G.
The validity of the muricid subfamily Ergalataxinae has recently been confirmed with molecular data, but its composition and the relationships among its constituent genera remain unclear. In order to investigate this, we use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I) to construct a Bayesian phylogeny of 52 ergalataxine species in 18 genera, representing c. 40 of the currently accepted species and 86 of the genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. Our results indicate the polyphyly of many traditional genera, including Morula, Pascula and Orania. In order to improve the correspondence between classification and phylogeny, we restrict the definition of Morula,...

A multibiomarker approach was developed on juvenile Atlantic tomcod (Microgadus tomcod) to evaluate the pertinence of this approach for low-cost screening assessment of the environmental quality of various coastal sites within estuaries. Several biometric indices and biomarkers (ethoxyresorufin-O-deethylase (EROD) activity, metallothionein concentration, and immune responses) were investigated on immature and maturing tomcods (a parts per thousand currency sign31 months) collected in four environmentally contrasted sites in the St. Lawrence Estuary (SLE). Simultaneous examination of various age classes provides the opportunity to detect short-term responses in sensitive young-of-the-year fish (e.g., EROD induction) and longer-time effects associated with...

Autores: Huret, Martin; Sourisseau, Marc; Petitgas, Pierre; Struski, Caroline; Leger, Fabien; Lazure, Pascal.
Multiple year oceanographic simulations (hindcast) are identified as a priority oceanography product for fisheries and environment studies since they provide a unique continuous long-term dataset allowing integrated assessment of the ocean state and evolution. We performed a 37 year (1972–2008) hindcast run with a coupled physical–biogeochemical model in the Bay of Biscay. The coupled model and the hindcast configuration are described. A model skill assessment is performed with a large set of in-situ data. Average seasonal currents show major circulation patterns over the shelf. Among tracers, temperature and salinity have the best agreement, ahead of nitrates and silicates, chlorophyll, and finally phosphates and ammonium. For chlorophyll, improved...

By the end of the 20th century, many of the coastal lagoons along the French Mediterranean coast showed insufficient water quality and degraded ecosystem states due to anthropogenic impacts. Among these, nutrient over-enrichment, resulting in eutrophication, has been a major concern. The EU Water Framework Directive (WFD) has initiated public action to improve their water quality and ecosystem state using an approach rooted in restoration ecology. Here we analyze how this has been applied for the coastal lagoons in South France, considering eutrophication as an example of ecosystem degradation and oligotrophication as the corresponding trajectory for ecological restoration of the eutrophied coastal lagoons. Oligotrophication trajectories, initiated by the...

This study considers how to reconcile different spatial scales to find the best common denominator to be used as an ecosystem-based management unit. For this, two fishery production zones differing ecologically, economically, legally and institutionally were investigated. The first case study is located within French territorial waters, in a MPA created in 2007- the Parc Naturel Marin d'Iroise (PNMI). The second case study, the Bay of Biscay, covers both territorial waters and the French exclusive economic zone. The paper adopts a multidisciplinary approach. Relevant questions concern how marine space is shared between exploited species and fishing fleets, especially the spatial mobility strategies they employ.

The increasing global consumption of seafood has led to increased trade among nations, accompanied by mislabeling and fraudulent practices that have rendered authentication crucial. The multi-isotope ratio analysis is considered as applicable tool for evaluating geographical authentications but requires information and experience to select target elements such as isotopes, through a distinction method based on differences in habitat and physiology due to origin. The present study examined recombination conditions of multi-elements that facilitated geographically distinct classifications of the clams to sort out appropriate elements. Briefly, linear discriminant analysis (LDA) analysis was performed according to several combinations of five stable isotopes...

This study examines the effects of increasing salinity on fish assemblage structure in the Casamance Estuary, Senegal. using a series of indices. The study data were derived from commercial fishery surveys conducted between April and July 2005. Analysis of within-trophic-group diversity in the Casamance Estuary shows a significant drop in the diversity of apex predators in the upper. more saline reaches of the estuary. By contrast. primary consumers adapted well to salinity changes and exhibited higher taxonomic diversity in the upper reaches of the estuary than in the lower reaches. The findings also indicate decreases in average sizes of the landed species and the trophic levels among fish catches in the direction of the upper reaches. However, the catch...

A multi-model assessment of the impact of currents, waves and wind in modelling surface drifters and oil spill

Validation of oil spill forecasting systems suffers from a lack of data due to the scarcity of oil slick in-situ and satellite observations. Drifters (surface drifting buoys) are often considered as proxy for oil spill to overcome this problem. However, they can have different designs and consequently behave in a different way at sea, making it not straightforward to use them for oil spill model validation purposes and to account for surface currents, waves and wind when modelling them. Stemming from the need to validate the MEDESS4MS (Mediterranean Decision Support System for Marine Safety) multi-model oil spill prediction system, which allows access to several ocean, wave and meteorological operational model forecasts, an exercise at sea was carried out...

A Multi-Observation Least-Squares Inversion for GNSS-Acoustic Seafloor Positioning
Provedor de dados: 5
Autores: Sakic, Pierre; Ballu, Valerie; Royer, Jean-yves.
Monitoring deformation on the seafloor is a major challenge for modern geodesy and a key to better understanding tectonic processes and assess related hazards. The extension of the geodetic networks offshore can be achieved by combining satellite positioning (GNSS) of a surface platform with acoustic ranging to seafloor transponders. This approach is called GNSS-Acoustic (GNSS-A). The scope of this work is to provide a tool to identify and quantify key points in the error budget of such experiment. For this purpose, we present a least-squares inversion method to determine the absolute position of a seafloor transponder array. Assuming the surface platform is accurately positioned by GNSS, the main observables are the two-way travel time in water between...

A Multiparametric Nonlinear Regression Approach for the Estimation of Global Surface Ocean pCO(2) Using Satellite Oceanographic Data
Provedor de dados: 5
Autores: Krishna, Kande Vamsi; Shanmugam, Palanisamy; Nagamani, Pullaiahgari Venkata.
Estimation of the partial pressure of carbon dioxide (pCO(2)) and its space-time variability in global surface ocean waters is essential for understanding the carbon cycle and predicting the future atmospheric CO2 concentration. Until recently, only basin-scale distribution of pCO(2) has been reported by using satellite-derived climatological data due to the lack of models for global-scale applications. In the present work, a multiparametric nonlinear regression (MPNR) for the estimation of global-scale distribution of pCO(2) on the ocean surface is developed using continuous in-situ measurements of pCO(2), chlorophyll-a (Chla) concentration, sea surface temperature (SST), and sea surface salinity (SSS) obtained on a number of cruise programs in various...

As a natural sediment trap, the marine sediments of the sheltered central part of the Maldives Inner Sea represent an exceptional archive for paleoenvironmental and climate changes in the equatorial Indian Ocean. To evaluate the complex interplay between high-latitude and monsoonal climate variability, related dust fluxes, and regional oceanographic responses, we focused on Fe/Al, Ti/Al and Si/Ca ratios as proxies for terrigenous sediment delivery and total organic carbon (TOC) and Br XRF counts as proxies for marine productivity. Benthic foraminiferal fauna distributions, grain size and stable delta O-18 and delta C-13 data were used for evaluating changes in the benthic ecosystem and changes in the intermediate water circulation, bottom water current...

Stalagmite Orum-1 from a cave near Orumana in northwestern Namibia provides a multi-proxy record of regional drying with increasing global-scale warmth over the last 47 kyr, in a region with few long well-dated location specific paleoclimate records. Data from Stalagmite Orum-1 include carbon and oxygen stable isotope ratios, proportions of aragonite and calcite, pronouncedly differing petrographic fabrics, positions of layer-bounding surfaces, variation in layer-specific width, and changes in layer thickness, all of which combine to support change from wetter to drier conditions. Combined with fourteen U-Th ages, they suggest that climate was wetter in northwestern Namibia during globally cold MIS 3 than it is today, and with more grass than is present...

Long-chain diols have been detected in a wide range of environments and have been used to reconstruct past environmental changes, however only a few long-term records exist to date. Here we reconstructed past environmental changes in the central Sea of Okhotsk over the last 1.5 million years, covering the Mid-Pleistocene Transition (MPT). Sea surface temperatures (SST) reconstructed using the Long-Chain Diol Index (LDI) reflects glacial/interglacial changes. However, when compared with other organic paleothermometers (Uk’37 and TEXL86) the LDI-SST is lower during interglacials and similar or higher during glacials, possibly suggesting a shift of diol production season during interglacials. The LDI-SST does not change in periodicity around the MPT as...

A multi-scale study of the interface between natural fibres and a biopolymer
Provedor de dados: 5
Autores: Le Duigou, Antoine; Baley, Christophe; Grohens, Yves; Davies, Peter; Cognard, Jean Yves; Creach Cadec, Romain; Sohier, Laurent.
A significant recent development in the composite field is the appearance of biocomposites (biopolymers reinforced by plant fibres) which combine mechanical performance and low environmental impacts. However, to replace conventional composites a significant effort is needed to understand their mechanical behaviour under complex loading (both in-plane and out-of-plane). The interfacial behaviour (fibre/matrix) of these materials also requires particular attention in order to optimize mechanical properties. With this aim modified Arcan, transverse tension and microdroplet debonding tests have been performed on flax reinforced PLLA biocomposites, as very few data of this type are available.  The out-of-plane tensile and tensile-shear properties of these...

A multistrain approach to studying the mechanisms underlying compatibility in the interaction between Biomphalaria glabrata and Schistosoma mansoni
Provedor de dados: 5

In recent decades, numerous studies have sought to better understand the mechanisms underlying the compatibility between Biomphalaria glabrata and Schistosoma mansoni. The developments of comparative transcriptomics, comparative genomics, interactomics and more targeted approaches have enabled researchers to identify a series of candidate genes. However, no molecular comparative work has yet been performed on multiple populations displaying different levels of compatibility. Here, we seek to fill this gap in the literature. We focused on B. glabrata FREPs and S. mansoni SmPoMucs, which were previously demonstrated to be involved in snail/schistosome compatibility. We studied the expression and polymorphisms of these factors in combinations of snail and...

A multitracer approach to assess the spatial contamination pattern of hake (Merluccius merluccius) in the French Mediterranean
Provedor de dados: 5
Autores: Cresson, Pierre; Bouchoucha, Marc; Morat, Fabien; Miralles, Francoise; Chavanon, Fabienne; Loizeau, Veronique; Cossa, Daniel.
Chemical contamination levels and stable isotope ratios provide integrated information about contaminant exposure, trophic position and also biological and environmental influences on marine organisms. By combining these approaches with otolith shape analyses, the aim of the present study was to document the spatial variability of Hg and PCB contamination of the European hake (Merluccius merluccius) in the French Mediterranean, hypothesizing that local contaminant sources, environmental conditions and biological specificities lead to site-specific contamination patterns. High Hg concentrations discriminated Corsica (average: 1.36 ± 0.80 μg g− 1 dm) from the Gulf of Lions (average values &lt; 0.5 μg g− 1 dm), where Rhône River input caused high PCB burdens....

A multivariate indicator to monitor changes in spatial patterns of age-structured fish populations
Provedor de dados: 5
Autores: Petitgas, Pierre; Poulard, Jean-charles.
Quantitative analysis of the spatial patterns in age-structured fish populations provides a useful complement to stock assessment methods. The spatial distribution of an age-structured population is characterized by indicators for location, dispersion and aggregation, which are estimated from survey data. The times series of spatial indicators are organised in a 3D data structure with dimensions along indicators, age classes and years. Multi factor analysis (MFA) is applied to quantify the reproducibility in time of the multivariate structure between age classes and indicators. MFA computes the mean annual pattern over the age classes. The deviation around that pattern in each year is also quantified. A multivariate indicator that characterise the spatial...

A Multivariate Regression Approach to Adjust AATSR Sea Surface Temperature to In Situ Measurements
Provedor de dados: 5
Autores: Tandeo, Pierre; Autret, Emmanuelle; Piolle, Jean-francois; Tournadre, Jean; Ailliot, Pierre.
The Advanced Along-Track Scanning Radiometer (AATSR) onboard Envisat is designed to provide very accurate measurements of sea surface temperature (SST). Using colocated in situ drifting buoys, a dynamical matchup database (MDB) is used to assess the AATSR-derived SST products more precisely. SST biases are then computed. Currently, Medspiration AATSR SST biases are discrete values and can introduce artificial discontinuities in AATSR level-2 SST fields. The new AATSR SST biases presented in this letter are continuous. They are computed, for nighttime and best proximity confidence data, by linear regression with different MDB covariables (wind speed, latitude, aerosol optical depth, etc.). As found, the difference between dual-view and nadir-only SST...

A mussel (Mytilus edulis) tissue certified reference material for the marine biotoxins azaspiracids
Provedor de dados: 5
Autores: Mccarron, Pearse; Giddings, Sabrina D.; Reeves, Kelley L.; Hess, Philipp; Quilliam, Michael A.
Azaspiracids (AZAs) are lipophilic biotoxins produced by marine algae that can contaminate shellfish and cause human illness. The European Union (EU) regulates the level of AZAs in shellfish destined for the commercial market, with liquid chromatography-mass spectrometry (LC-MS) being used as the official reference method for regulatory analysis. Certified reference materials (CRMs) are essential tools for the development, validation, and quality control of LC-MS methods. This paper describes the work that went into the planning, preparation, characterization, and certification of CRM-AZA-Mus, a tissue matrix CRM, which was prepared as a wet homogenate from mussels (Mytilus edulis) naturally contaminated with AZAs. The homogeneity and stability of...

The development of multi-analyte methods for lipophilic shellfish toxins based on liquid chromatography-mass spectrometry permits rapid screening and analysis of samples for a wide variety of toxins in a single run. Validated methods and appropriate certified reference materials (CRMs) are required to ensure accuracy of results. CRMs are essential for accurate instrument calibration, for assessing the complete analytical method from sample extraction to data analysis and for verifying trueness. However, CRMs have hitherto only been available for single toxin groups. Production of a CRM containing six major toxin groups was achieved through an international collaboration. Preparation of this material, CRM-FDMT1, drew on information from earlier studies as...

A Mussel's Life Around Deep-Sea Hydrothermal Vents
Provedor de dados: 5
Autores: Duperron, Sebastien; Gaudron, Sylvie M.; Laming, Sven.
Hydrothermal vents are places where seawater exits cracks in the sea floor, having been super-heated and enriched with metals and minerals deep in the underlying bedrock. They are an example of an ecosystem based on chemosynthesis, where life is sustained by energy from chemicals rather than energy from sunlight. The discovery of an abundance of life around deep-sea hydrothermal vents emitting hot and toxic fluids demonstrated that animals and other organisms could thrive in the dark, cold and high-pressure deep oceans. Mussels are among the most studied animals found near hydrothermal vents. Scientists discovered that mussels rely on a close, living relationship—a “symbiosis”—with bacteria for their nutrition. In this symbiosis, bacteria use chemicals...

A near-inertial mode observed within a Gulf Stream warm-core ring
Provedor de dados: 5
Autores: Joyce, Terrence M.; Toole, John M.; Klein, Patrice; Thomas, Leif N.
Layering of ocean velocity fine structure has been coherently observed across the entire extent of a Gulf Stream warm-core ring using a shipboard acoustic Doppler current profiler system in September 2009 and independently sampled as the ring transited a moored array. Lines of constant velocity phase generally followed isopycnals as they deepened within the ring center. We also observed a clear separation of the vertical structure of the flows associated with the ring (of order 0.5m/s) with the shorter (200m) and less energetic (similar to 0.2m/s) flows of the velocity fine structure, which was further observed to rotate clockwise with increasing depth, consistent with downward propagating near-inertial waves (NIWs). Observations are consistent with a...

Autores: Bellec, Laure; Cambon-bonavita, Marie-anne; Cueff-gauchard, Valerie; Durand, Lucile; Gayet, Nicolas; Zeppilli, Daniela.
Deep-sea hydrothermal vent meiofauna have been the focus of recent research and the discovery of an abundant well-adapted free-living marine nematode on the Mid-Atlantic Ridge offers new perspectives on adaptations to the vent environment. Indeed, knowledge concerning biological interactions of microbes and meiofauna in marine extreme environments is scarce, especially for nematodes. In this study, we used microscopic observations [fluorescence in situ hybridization (FISH) and scanning electron microscopy (SEM)] and metabarcoding of 16S rRNA to characterize the bacterial community of the nematode species Oncholaimus dyvae, an overlooked but ecologically important vent organism. Detection of bacteria in the buccal cavity and on the cuticle (SEM) and...

A neural network-based estimate of the seasonal to inter-annual variability of the Atlantic Ocean carbon sink
Provedor de dados: 5
Autores: Landschuetzer, P.; Gruber, N.; Bakker, D. C. E.; Schuster, U.; Nakaoka, S.; Payne, M. R.; Sasse, T. P.; Zeng, J.
The Atlantic Ocean is one of the most important sinks for atmospheric carbon dioxide (CO2), but this sink has been shown to vary substantially in time. Here we use surface ocean CO2 observations to estimate this sink and the temporal variability from 1998 through 2007 in the Atlantic Ocean. We benefit from (i) a continuous improvement of the observations, i. e. the Surface Ocean CO2 Atlas (SOCAT) v1.5 database and (ii) a newly developed technique to interpolate the observations in space and time. In particular, we use a two-step neural network approach to reconstruct basin-wide monthly maps of the sea surface partial pressure of CO2 (pCO(2)) at a resolution of 1 degrees x 1 degrees From those, we compute the air-sea CO2 flux maps using a standard gas...

A new analysis of hypoxia tolerance in fishes using a database of critical oxygen level (P-crit)
Provedor de dados: 5
Autores: Rogers, Nicholas J.; Urbinalt, Mauricio A.; Reardon, Erin E.; Mckenzie, David J.; Wilsonl, Rod W.
Hypoxia is a common occurrence in aquatic habitats, and it is becoming an increasingly frequent and widespread environmental perturbation, primarily as the result of anthropogenic nutrient enrichment and climate change. An in-depth understanding of the hypoxia tolerance of fishes, and how this varies among individuals and species, is required to make accurate predictions of future ecological impacts and to provide better information for conservation and fisheries management. The critical oxygen level (P-crit)m has been widely used as a quantifiable trait of hypoxia tolerance. It is defined as the oxygen level below which the animal can no longer maintain a stable rate of oxygen uptake (oxyregulate) and uptake becomes dependent on ambient oxygen...

A new application of principal response curves for summarizing abrupt and cyclic shifts of communities over space
Provedor de dados: 5
Autores: Auber, Arnaud; Travers-trolet, Morgane; Villanueva, Ching-maria; Ernande, Bruno.
There is a growing need to easily describe and synthesize the dynamics of ecosystems’ components in space and time. Most multivariate analyses provide ordination diagrams or biplots that are too cluttered to allow simple reading and are unfamiliar to most users. To overcome such difficulties, a novel application of principal response curves (PRCs) is proposed. Principal response curves are traditionally used to assess treatment effects on community structure measured repeatedly over time. In this new application, the tested factor and the repeated-observation axis are replaced by time and space, respectively. The georeferencing of sampling sites permits to produce an easy-to-read map that summarizes both the temporal dynamics of the community and the...

A new approach to determine the distributional effects of quota management in fisheries
Provedor de dados: 5
Autores: Bellanger, Manuel; Macher, Claire; Guyader, Olivier.
Quota allocation mechanisms have distributional effects that are highly relevant to the economic organization of fisheries. In France, where fishing allocations are non-transferable, quotas are shared among Producer Organizations (POs) based on the historical landings of their members. Each PO is then responsible for implementing their own internal rules that provide individual or collective allocations to their members. This study investigates the distributional effects of the various quota management systems adopted by POs on quotas and production for the Bay of Biscay sole fishery. A comparison between initial allocations by vessel based on historical landings and actual observed landings is presented. Inequality metrics are used to quantify...

A new approach to recruitment overfishing diagnosis is presented. We hypothesize that condition of recruits should increase when recruitment failures are caused by fishing activity. This would be a consequence of the increase in trophic resource availability, because the population is smaller than that which the ecosystem could support. Temporal series of hake recruit condition were calculated from MEDITS survey data collected in Mediterranean geographical sub-areas (GSAs) 1, 6, 17 and 19 from 1994 to 2015. Multiple linear regressions were used to analyse the relationship between mean annual condition and abundance of recruits and climatic indices in each GSA. Significant correlations were only detected in GSA 6, where 69% of condition variability was...

A new assessment of the error budget of global mean sea level rate estimated by satellite altimetry over 1993-2008
Provedor de dados: 5
Autores: Ablain, M.; Cazenave, A.; Valladeau, G.; Guinehut, S.
A new error budget assessment of the global Mean Sea Level (MSL) determined by TOPEX/Poseidon and Jason-1 altimeter satellites between January 1993 and June 2008 is presented using last altimeter standards. We discuss all potential errors affecting the calculation of the global MSL rate. We also compare altimetry-based sea level with tide gauge measurements over the altimetric period. Applying a statistical approach, this allows us to provide a realistic error budget of the MSL rise measured by satellite altimetry. These new calculations highlight a reduction in the rate of sea level rise since 2005, by similar to 2 mm/yr. This represents a 60% reduction compared to the 3.3 mm/yr sea level rise (glacial isostatic adjustment correction applied) measured...

A New Assessment of Thioester-Containing Proteins Diversity of the Freshwater Snail Biomphalaria glabrata
Provedor de dados: 5
Autores: Duval, David; Pichon, Rémi; Lassalle, Damien; Laffitte, Maud; Gourbal, Benjamain; Galinier, Richard.
Thioester-containing proteins (TEPs) superfamily is known to play important innate immune functions in a wide range of animal phyla. TEPs are involved in recognition, and in the direct or mediated killing of several invading organisms or pathogens. While several TEPs have been identified in many invertebrates, only one TEP (named BgTEP) has been previously characterized in the freshwater snail, Biomphalaria glabrata. As the presence of a single member of that family is particularly intriguing, transcriptomic data and the recently published genome were used to explore the presence of other BgTEP related genes in B. glabrata. Ten other TEP members have been reported and classified into different subfamilies: Three complement-like factors (BgC3-1 to BgC3-3),...

Provedor de dados: 5
Autores: Plouviez, Sophie; Faure, Baptiste; Le Guen, Dominique; Lallier, Francois; Bierne, Nicolas; Jollivet, Didier.
Comparative phylogeography of deep-sea hydrothermal vent species has uncovered several genetic breaks between populations inhabiting northern and southern latitudes of the East Pacific Rise. However, the geographic width and position of genetic clines are variable among species. In this report, we further characterize the position and strength of barriers to gene flow between populations of the deep-sea vent mussel Bathymodiolus thermophilus. Eight allozyme loci and DNA sequences of four nuclear genes were added to previously published sequences of the cytochrome c oxidase subunit I gene. Our data confirm the presence of two barriers to gene flow, one located at the Easter Microplate (between 21 degrees 33'S and 31 degrees S) recently described as a hybrid...

A new bathyphotometer has been developed by the Oceanographic Laboratory of the French Naval Academy which has performed a series of in situ bioluminescence: measurements since 1994. It is used as an additional probe to a Seabird (R) CTD. It measures planktonic bioluminescence. It is associated with a SeaTech (R) fluorometer. The Armorican shelf has particularly been investigated since July 1994. Results obtained in January and April 1995 off Brittany (France), at the entrance to the Bay of Douarnenez and in the northern Bay of Biscay are presented as examples. A method to separate the bioluminescence background from sharp peaks is presented. The strength of bioluminescence signals was related to seasonal planktonic biomass fluctuations, low in winter,...

A new class of predator prey models with interactions described by thresholds
Provedor de dados: 5
Autores: Trenkel, Verena; Rochet, Marie-joelle; Sari, Tewfik.
There exists an urgent need in fisheries science for simple models for assessing the impact of fishing on the dynamics of fish communities. We present a new class of predator prey models that describe the relationship between predators and their prey by piecewise-linear differential equations. Interactions are governed by threshold values for population abundances. The simplest model has four distinct cases with different asymptotic stable states. The model allows for fishing mortality on both predator and prey. If fishing mortality on either the predator, the prey or both are varied, the system might move to new stable states. The threshold values act as reference points for fishing exploitation, as they indicate a structural change in the predator-prey...

Cold-water coral (CWC) habitats can form complex structures which provide refuge, nursery grounds and physical support for a diversity of other living organisms, but despite their ecological significance, CWCs are still vulnerable to human pressures such as fishing, pollution, ocean acidification and global warming Providing coherent and representative conservation of vulnerable marine ecosystems including CWCs is one of the aims of the Marine Protected Areas networks being implemented across European seas and oceans under the EC Habitats Directive, the Marine Strategy Framework Directive and the OSPAR Convention. In order to adequately represent ecosystem diversity these initiatives require a standardised habitat classification that organises the variety...

A new climate index controlling winter wave activity along the Atlantic coast of Europe: The West Europe Pressure Anomaly
Provedor de dados: 5
Autores: Castelle, Bruno; Dodet, Guillaume; Masselink, Gerd; Scott, Tim.
A pioneering and replicable method based on a 66-year numerical weather and wave hindcast is developed to optimize a climate index based on the sea level pressure (SLP) that best explains winter wave height variability along the coast of western Europe, from Portugal to UK (36-52 degrees N). The resulting so-called Western Europe Pressure Anomaly (WEPA) is based on the sea level pressure gradient between the stations Valentia (Ireland) and Santa Cruz de Tenerife (Canary Islands). The WEPA positive phase reflects an intensified and southward shifted SLP difference between the Icelandic low and the Azores high, driving severe storms that funnel high-energy waves toward western Europe southward of 52 degrees N. WEPA outscores by 25-150% the other leading...

A new compilation of stomach content data for commercially-important pelagic fish species in the Northeast Atlantic
Provedor de dados: 5
Autores: Pinnegar, J. K.; Goni, N.; Trenkel, Verena; Arrizabalaga, H.; Melle, W.; Keating, J.; Oskarsson, G.
There is increasing demand for information on predator-prey interactions in the ocean as a result of legislative commitments aimed at achieving sustainable exploitation. However, comprehensive datasets are lacking for many fish species and this has hampered development of multispecies fisheries models and the formulation of effective food-web indicators. This work describes a new compilation of stomach content data for five pelagic fish species (herring, blue whiting, mackerel, albacore and bluefin tuna) sampled across the northeast Atlantic and submitted to the PANGAEA open-access data portal (www.pangaea.de). We provide detailed descriptions of sample origin and of the corresponding database structures. We describe the main results in terms of diet...

A new contribution to the Late Quaternary tephrostratigraphy of the Mediterranean: Aegean Sea core LC21
Provedor de dados: 5
Autores: Satow, C.; Tomlinson, E. L.; Grant, K. M.; Albert, P. G.; Smith, V. C.; Manning, C. J.; Ottolini, L.; Wulf, S.; Rohling, E. J.; Lowe, J. J.; Blockley, S. P. E.; Menzies, M. A.
Tephra layers preserved in marine sediments can contribute to the reconstruction of volcanic histories and potentially act as stratigraphic isochrons to link together environmental records. Recent developments in the detection of volcanic ash (tephra) at levels where none is macroscopically visible (so-called ‘crypto-tephra’) have greatly enhanced the potential of tephrostratigraphy for synchronising environmental and archaeological records by expanding the areas over which tephras are found. In this paper, crypto-tephra extraction techniques allow the recovery of 8 non-visible tephra layers to add to the 9 visible layers in a marine sediment core (LC21) from the SE Aegean Sea to form the longest, single core record of volcanic activity in the Aegean Sea....

Autores: Pianezze, J.; Barthe, C.; Bielli, S.; Tulet, P.; Jullien, Swen; Cambon, Gildas; Bousquet, O.; Claeys, M.; Cordier, E.
Ocean-Waves-Atmosphere (OWA) exchanges are not well represented in current Numerical Weather Prediction (NWP) systems, which can lead to large uncertainties in tropical cyclone track and intensity forecasts. In order to explore and better understand the impact of OWA interactions on tropical cyclone modelling, a fully coupled OWA system based on the atmospheric model Meso-NH, the oceanic model CROCO and the wave model WW3 and called MSWC was designed and applied to the case of tropical cyclone Bejisa (2013-2014). The fully coupled OWA simulation shows good agreement with the literature and available observations. In particular, simulated significant wave height is within 30 cm of measurements made with buoys and altimeters. Short-term (&lt; 2 days)...

A new deep-sea genus of nannastacidae (Crustacea, cumacea) from the lucky strike hydrothermal vent field (Azores triple junction, mid-atlantic ridge)
Provedor de dados: 5
Autores: Corbera, J; Segonzac, Michel; Cunha, M.
A new cumacean genus and species, Thalycrocuma sarradini gen. et sp. nov., belonging to the family Nannastacidae is described from several sites of the Lucky Strike hydrothermal vent field (Mid-Atlantic Ridge, 37N, 1700 m depth). The new genus differs from others in the family by males lacking exopods on the pereopods 3 and 4 and having an antenna with a five-articulate peduncle and a short flagellum. This is the first cumacean species that could be considered, at the moment, as endemic from hydrothermal vent areas. Data on the accompanying fauna including other cumacean species (Cyclaspis longicaudata, Bathycuma brevirostre, Procampylaspis sp. and Makrokylindrus sp.) and some ecological remarks are included. A key for the currently known genera of the...

A new definition of the South-East Madagascar Bloom and analysis of its variability
Provedor de dados: 5
Autores: Dilmahamod, Ahmad Fehmi; Penven, Pierrick; Aguiar gonzalez, B.; Reason, C. J. C.; Hermes, J. C.
The South‐East Madagascar Bloom occurs in an oligotrophic region of the South‐West Indian Ocean. Phase‐locked to austral summer, this sporadic feature exhibits substantial temporal and spatial variability. Several studies, with different hypotheses, have focused on the initiation mechanism triggering the bloom but none has been as yet clearly substantiated. With 19‐years of ocean colour dataset available as well as in‐situ measurements (Argo profiles), the time is ripe to review this feature. The bloom is characterized in a novel manner and a new bloom index is suggested, yielding 11 bloom years, including 3 major bloom years (1999, 2006 and 2008). Spatially, the bloom varies from a mean structure (22° S‐32° S; 50° E‐∼70°E) both zonally and meridionally. A...

Provedor de dados: 5
Autores: Lunven, Michel; Lehaitre, Michel; Nascimben, Eric; Rouvillain, Julien; Berric, Roger; Le Gall, Erwan; Gentien, Patrick.
A new video-microscope has been developed for in situ investigation on marine particles. A field of view is produced by a laser beam at 473 nm. Individual cells or particles that entered this field of view appear as individual diffraction-limited spots of light, which are resolved from the dark background. A mobile high-pass optical filter (610 nm) can be controlled and displaced in front of the CCD camera, allowing simultaneously imaging and discrimination between fluorescing and non-fluorescing particles. We have the possibility to add a band pass filter for phycoerytrin detection. The system allows white light visualisation of particles ranging from 10 µm to several millimetres, depending on the zoom magnification. With the 610 nm high pass filter, the...

A new benthic station equipped with oxygen microelectrodes and environmental sensors was developed by Laboratoire des Sciences du Climat et de L’Environnement (LSCE) and Division Technique of the Institut National des Sciences de L’Univers (DT-INSU) to perform in situ time series monitoring of sediment oxygen demand, linked to the mineralization of organic matter. The time series typically cover periods of 2-3 months, with a base frequency of 1 set of oxygen profiles per day. The profiling head assessed the lateral heterogeneity of the sediment oxygen demand at the beginning of the time series over a 0.8-m long rectangle to discriminate spatial and temporal variability. A continuous recalibration is performed using a moored oxygen optode anchored to the...

A New Discrimination Scheme for Oceanic Ferromanganese Deposits using High Field Strength and Rare Earth Elements
Provedor de dados: 5
Autores: Josso, P.; Pelleter, Ewan; Pourret, O.; Fouquet, Yves; Etoubleau, Joel; Cheron, Sandrine; Bollinger, C.
Ferromanganese (Fe-Mn) deposits constitute a ubiquitous mineral type in oceanic settings, with metal (Cu, Ni, Zn, Co, Pt) and rare earth elements (REE) enrichments of potential economic interest. Routine analysis of trace elements by ICP-MS has advanced our understanding of the impact of hydrogenetic, diagenetic and hydrothermal processes on the mobility and interaction of high field strength elements (HFSE: Zr, Ti) and REE and yttrium (REY) with Fe-Mn oxyhydroxides. Recent discoveries in the French exclusive economic zone (EEZ) of Wallis and Futuna (southwest Pacific Ocean) have brought new insight to the formation of low temperature (LT) hydrothermal Mn deposits and lead us to reconsider the classification and discrimination diagrams for of Fe-Mn...

A new generation of tools for trawls Dynamic numerical simulation
Provedor de dados: 5
Autores: Vincent, Benoit.
IFREMER and ECN have been working together for almost ten years on problems related to the numerical simulation of trawls and more generally the numerical simulation of any kind of fishing gear. To develop such a simulation tool, we need to build (i) a software in which all the parameters of the fishing gear are taken into account; (ii) a software that computes the physical behaviour of the fishing gear (static or dynamic); (iii) a software to visualise the results of calculations. The most complex part of this work most of the time rests in the point (i), because of the huge amount of parameters and elements of an actual fishing net.   We have already developed a tool (point (i), named Cachalot) to describe a trawl. However, this software was designed to...

Combined microwave brightness temperature measurements from recent L- and dual C-band satellite radiometers provide new estimates of surface wind speed structure in Tropical Cyclones which enhances temporal sampling capability for gale (34-knots), damaging (50-knots) and destructive (64-knots) wind radii.  Wind radii estimates in Tropical Cyclones (TC) are crucial to help determine the TC wind structure for the production of effective warnings and to constrain initial conditions for a number of applications. In that context, we report on the capabilities of a new generation of satellite microwave radiometers operating at L-band frequency (~1.4 GHz) and dual C-band (~6.9 and 7.3 GHz). These radiometers provide wide swath (&gt; 1000 km) coverage at a spatial...

The MiniFluo-UV is a new glider-compatible optical sensor for measurements of dissolved organic matter (DOM) in natural waters. The working principle, sensor design and challenges faced during the validation phase are reported. The first in situ application of the sensor during three glider deployments in the NW Mediterranean sea (spring, summer, and fall) are also presented. For these campaigns, the two channels of the sensor were adjusted to target Tryptophan-like (excitation/emission wavelengths λEx/λEm: 275/340 nm) and Phenanthrene-like (λEx/λEm: 255/360 nm) fluorescence. These were chosen because they represent fluorophores of interest commonly found in seawater. While Tryptophan (an amino-acid believed to be a by-product of biological activity) is...

A new lineage of Conoidea (Gastropoda: Neogastropoda) revealed by morphological and molecular data
Provedor de dados: 5
Autores: Kantor, Yuri I.; Strong, Ellen E.; Puillandre, Nicolas.
The hyperdiverse group of venomous Conoidea has eluded attempts to construct a robust and stable classification owing to the absence of a robust and stable phylogenetic framework. New molecular data have greatly enhanced our understanding of conoidean evolution, allowing the construction of a new family-level classification. This expanding framework has also allowed the discovery of several independent lineages that merit recognition at familial rank. One of these, based on seven specimens collected over more than 20 years from deep waters off New Caledonia, represents a unique, monotypic lineage closely related to Mitromorphidae, which we here name as the new family Bouchetispiridae. This new lineage bears a unique combination of teleoconch, protoconch...

A new 46-meter-long coring system was tested successfully during cruise 191 of research vessel (R/V) Knorr in September 2007. During sea trials in water depths of 4.6 kilometers on the Bermuda Rise, coring operations from the vessel—operated by the Woods Hole Oceanographic Institution (WHOI)—successively recovered piston cores increasing in length from 26 to 38 meters, with sediment recovery at 85–89% of the core barrel length. An additional 25-meter core was recovered in 670 meters of water on the upper continental slope off New Jersey.  The Bermuda Rise location, which is a well-sedimented drift deposit at the northeastern margin of the rise, has been cored many times previously, including by R/V Knorr's giant piston corer in 1973, by R/V Marion...

A New Mechanism for Mode Water Formation involving Cabbeling and Frontogenetic Strain at Thermohaline Fronts
Provedor de dados: 5
Autores: Thomas, Leif N.; Shakespeare, Callum J.
A simple analytical model is used to elucidate a potential mechanism for steady-state mode water formation at a thermohaline front that involves frontogenesis, submesoscale lateral mixing, and cabbeling. This mechanism is motivated in part by recent observations of an extremely sharp, density-compensated front at the North Wall of the Gulf Stream. Here, the intergyre, along-isopycnal, salinity-temperature difference is compressed into a span of a few kilometers, making the flow susceptible to cabbeling. The sharpness of the front is caused by frontogenetic strain, which is presumably balanced by submesoscale lateral mixing processes. The balance is studied with the simple model, and a scaling is derived for the amount of water mass transformation resulting...

A New Method of De-Aliasing Large-Scale High-Frequency Barotropic Signals in the Mediterranean Sea
Provedor de dados: 5
Autores: Hu, Denghui; Xu, Yongsheng.
With the development of satellite observation technology, higher resolution and shorter return cycle have also placed higher demands on satellite data processing. The non-tide high-frequency barotropic oscillation in the marginal sea produces large aliasing errors in satellite altimeter observations. In previous studies, the satellite altimeter aliasing correction generally relied on a few bottom pressure data or the model data. Here, we employed the high-frequency tide gauge data to extract the altimeter non-tide aliasing correction in the west Mediterranean Sea. The spatial average method and EOF analysis method were adopted to track the high-frequency oscillation signals from 15 tide gauge records (TGs), and then were used to correct the aliasing errors...

A new method to control error rates in automated species identification with deep learning algorithms
Provedor de dados: 5
Autores: Villon, Sébastien; Mouillot, David; Chaumont, Marc; Subsol, Gérard; Claverie, Thomas; Villéger, Sébastien.
Processing data from surveys using photos or videos remains a major bottleneck in ecology. Deep Learning Algorithms (DLAs) have been increasingly used to automatically identify organisms on images. However, despite recent advances, it remains difficult to control the error rate of such methods. Here, we proposed a new framework to control the error rate of DLAs. More precisely, for each species, a confidence threshold was automatically computed using a training dataset independent from the one used to train the DLAs. These species-specific thresholds were then used to post-process the outputs of the DLAs, assigning classification scores to each class for a given image including a new class called “unsure”. We applied this framework to a study case...

A new method to estimate planktonic oxygen metabolism using high‐frequency sensor measurements in mesocosm experiments and considering daytime and nighttime respirations
Provedor de dados: 5
Autores: Soulié, Tanguy; Mas, Sébastien; Parin, David; Vidussi, Francesca; Mostajir, Behzad.
Understanding how aquatic ecosystems respond to perturbations has emerged as a crucial way to predict the future of these ecosystems and to assess their capacity to produce oxygen and store atmospheric carbon. In this context, in situ mesocosm experiments are a useful approach for simulating disturbances and observing changes in planktonic communities over time and under controlled conditions. Within mesocosm experiments, the estimation of fundamental parameters such as gross primary production (GPP), net community production (NCP), and respiration (R) allows the evaluation of planktonic metabolic responses to a perturbation. The continuous estimation of these metabolic parameters in real time and at high frequency is made possible by employing noninvasive...

A new ocean SAR cross-spectral parameter: definition and directional property using the global Sentinel-1 measurements
Provedor de dados: 5
Autores: Li, Huimin; Chapron, Bertrand; Mouche, Alexis; Stopa, Justin.
Space‐borne synthetic aperture radar (SAR) measurements have already been proven to be invaluable in detecting and quantifying properties of ocean swell systems. With the improved spatial resolution, Sentinel‐1 wave mode measurements can further be extended towards shorter scale waves, i.e. within the surface wave equilibrium range. In this study, a new parameter is derived from filtering SAR image cross‐spectra around range‐traveling intermediate wind waves (wavelengths 15‐20 m). This parameter captures both the radar cross section variability and its time evolution. Given the dependence of intermediate waves on local wind field, this parameter is statistically documented to confirm its sensitivity to both wind speed and wind direction. Comparable to...

A new operational classification of the Conoidea (Gastropoda)
Provedor de dados: 5
Autores: Bouchet, P.; Kantor, Yu. I.; Sysoev, A.; Puillandre, N.
A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s....

A new perspective on West African hydroclimate during the last deglaciation
Provedor de dados: 5
Autores: Parker, Andrew O.; Schmidt, Matthew W.; Jobe, Zane R.; Slowey, Niall C.
Widespread drought characterized the Heinrich 1 and Younger Dryas cold periods of the last deglaciation throughout much of Africa, causing large increases in dust emissions from the Sahara and Sahel. At the same time, increases in wind strength may have also contributed to dust flux, making it difficult to interpret dust records alone as reflecting changes in rainfall over the region. The Niger River has the third largest drainage basin in Africa and drains most of the Sahara and Sahel and thus preserves and propagates climatic signals. Here, we present new reconstructions of Niger Delta sea surface salinity and Niger River discharge for the last 20,000 years in order to more accurately reconstruct the onset of the Western African Monsoon system. Based on...

A New Photobioreactor for Continuous Microalgal Production in Hatcheries Based on External-Loop Airlift and Swirling Flow
Provedor de dados: 5
Autores: Loubiere, K; Olivo, Erell; Bougaran, Gael; Pruvost, J; Robert, Rene; Legrand, J.
This study deals with the scale of a new photobioreactor for continuous microalgal production in hatcheries. The combination of the state-of-art with the constraints inherent to hatcheries has turned the design into a closed, artificially illuminated and external-loop airlift configuration based on a succession of elementary modules, each one being composed of two transparent vertical interconnected columns. The liquid circulation is ensured pneumatically (air injections) with respect to a swirling motion (tangential inlets). A single module of the whole photobioreactor was built-up to scale its geometry (diameter and length) and to optimize its design (air sparger, tangential inlets). The volumetric productivities were predicted by modeling radiative...

The present paper describes a new type of floating platform that was specifically designed for estimating air–sea fluxes, investigating turbulence characteristics in the atmospheric surface boundary layer, and studying wind–wave interactions. With its design, it can be deployed in the open ocean or in shallow-water areas. The system is designed to be used from a research vessel. It can operate for ~10 h as a drifting wave rider and 3 h under power. Turbulence and meteorological instrument packages are placed at a low altitude (1–1.5 m). It was deployed for validation purposes during the Front de Marée, Variabilité (FROMVAR), 2011 experiment off the west coast of Brittany, France. Wind friction velocity and surface turbulent buoyancy flux were estimated...

Autores: Percopo, Isabella; Siano, Raffaele; Rossi, Rachele; Soprano, Vittorio; Sarno, Diana; Zingone, Adriana.
A new photosynthetic planktonic marine dinoflagellate, Azadinium dexteroporum sp. nov., is described from the Gulf of Naples (South Tyrrhenian Sea, Mediterranean Sea). The plate formula of the species, Po, cp, X, 4, 3a, 6, 6C, 5?S, 6'" and 2, is typical for this recently described genus. Azadinium dexteroporum is the smallest rep-resentative of the genus (8.5m average length, 6.2m average width) and shares the presence of a small antapical spine with the type species A.spinosum and with A.polongum. However, it differs from all other Azadinium species for the markedly asymmetrical Po plate and the position of the ventral pore, which is located at the right posterior end of the Po plate. Another peculiarity of A.dexteroporum is the pronounced concavity of...

A New Probabilistic Wave Breaking Model for Dominant Wind‐sea Waves Based on the Gaussian Field Theory
Provedor de dados: 5
Autores: Stringari, Ce; Prevosto, Marc; Filipot, Jean-francois; Leckler, Fabien; Guimaraes, Pv.
This paper presents a novel method for obtaining the probability wave of breaking (Pb) of deep water, dominant wind‐sea waves (that is, waves made of the energy within ±30% of the peak wave frequency) derived from Gaussian wave field theory. For a given input wave spectrum we demonstrate how it is possible to derive a joint probability density function between wave phase speed (c) and horizontal orbital velocity at wave crest (u) from which a model for Pb can be obtained. A non‐linear kinematic wave breaking criterion consistent with the Gaussian framework is further proposed. Our model would allow, therefore, for application of the classical wave breaking criterion (that is, wave breaking occurs if u/c &gt; 1) in spectral wave models which, to the...

A new procedure for interpolating satellite-derived Suspended Particulate Matters within the Previmer context
Provedor de dados: 5
Autores: Gohin, Francis; Bryere, Philippe; Perrot, Laurie.
After several years of experience in providing daily merged products of non-algal Suspended Particulate Matters (SPM) for forcing the light in the ecological model of Previmer ECO-MARS-3D, we have often observed poor quality SPM fields in winter due to the cloud cover. For this reason we propose a new interpolation scheme, multisensor and multitemporal, based on a first-guess field of daily SPM derived from a biweekly satellite climatology modified to take into account dynamically the effects of waves and tides. The contribution of waves and tide is simulated through a simple statistical model (multiplicative effects of the significant wave heights and tidal intensity) summing up the information coming out from the historical data set of SPM.

A New Process for Extracting Alginates from Laminaria digitata: Reactive Extrusion
Provedor de dados: 5
Autores: Vauchel, Peggy; Kaas, Raymond; Arhaliass, Abdellah; Baron, Regis; Legrand, Julien.
Alginates are natural polysaccharides that are extracted from brown seaweeds and widely used for their rheological properties. The main step in the extraction protocol used in the alginate industry is that of alkaline extraction. A batch process is used for this step, which is time-, water-, and reactant-consuming. The possibility of extracting by reactive extrusion was investigated. The reactive extrusion process appeared to be more efficient than the batch process for the alkaline extraction of alginates from Laminaria digitata in several key ways: Time demand is reduced from about an hour to only few minutes, water and reactant requirements are divided by more than a factor 2, extraction yield is 15% higher (relative enhancement), and the rheological...

A new rheological model for thixoelastic materials in subaqueous gravity driven flows
Provedor de dados: 5
Autores: Hermidas, Navid; Silva Jacinto, Ricardo; Eggenhuisen, Joris T.; Luthi, Stefan M.
A new viscoelastic constitutive model for subaqueous clay-rich gravity flows is presented. It is explained that for the materials which exhibit a minimum in their strain controlled flow curves the structure parameter must be a symmetric function of strain rate and stress. Therefore, the destruction of structure within the material is modeled using the dissipation energy. An expression for the elastic strain of the flowing structure is derived. The final set of equations can reproduce the viscosity bifurcation that clay suspensions may exhibit under a given load. This is explained to be important for prediction of the run-out distance of clay-rich gravity flows. The ability of the model to reproduce the general response of pasty materials to step stress and...

A new SNP-based vision of the genetics of sex determination in European sea bass (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Palaiokostas, Christos; Bekaert, Michael; Taggart, John B.; Gharbi, Karim; Mcandrew, Brendan J.; Chatain, Beatrice; Penman, David J.; Vandeputte, Marc.
Background: European sea bass (Dicentrarchus labrax) is one of the most important farmed species in Mediterranean aquaculture. The observed sexual growth and maturity dimorphism in favour of females adds value towards deciphering the sex determination system of this species. Current knowledge indicates the existence of a polygenic sex determining determination system that interacts with temperature. This was explored by restriction-site associated DNA (RAD) marker analysis in a test panel of 175 offspring that originated from a factorial cross between two dams and four sires from a single full-sib family.  Results: The first high-density single nucleotide polymorphism (SNP) based linkage map for sea bass was constructed, consisting of 6706 SNPs on 24...

A new starting point for the history of the central Atlantic
Provedor de dados: 5
Autores: Sahabi, Mohamed; Aslanian, Daniel; Olivet, Jean-louis.
A new starting point for the history of the central Atlantic. The first oceanic crust in the central Atlantic is usually thought to have a Middle Jurassic age. The new interpretation of the two key parameters, the African homologue of the East Coast Magnetic Anomaly and the situation of the Triassic salt basin of Morocco and Novia Scotia, shows that this age was underestimated by about 20 Ma. In our kinematic reconstruction, the first oceanic crust begins at the Late Sinemurian. This difference in age is crucial for the evolution of those margins and we discuss here its consequences.

The opening of the Equatorial and South Atlantic Oceans is still a matter of debate, particularly as concerns the locations of the intraplate deformation. We propose here a critical review of the kinematic models published since Bullard et al., 1965, based on a series of constraints: new interpretation of the magnetic anomalies, seafloor isochrons, flow lines, fracture zones, continental and oceanic homologous structures and radiometric dating of igneous rocks. All of these models present numerous unexplained misfits (gaps, overlaps and misalignments). We present here a new evolution of the Equatorial and South Atlantic Ocean from the tightest reconstruction to Chron C34. This new model confirms the hypothesis of a northward propagation of the South...

Autores: Vigneau, Joel; Mahevas, Stephanie.
Measuring fish on a market or on board a vessel is the most common action taken by biologists all around the world to gather data for stock assessment. The samples coming from this kind of survey are of vector type and are not straightforward to analyse and compare. This paper proposes a generic tool that enables to investigate in any multinomial like sampling scheme. The use of this tool will be discussed based on examples from two different sampling designs. One is a sampling of commercial market categories and the other is a métier based sampling. The research of outliers, misallocated samples or potential bias, the stratification and the analysis of within and between strata variance will be discussed with the objective of constructing the best...

Autores: Korosov, Anton; Rampal, Pierre; Pedersen, Leif Toudal; Saldo, Roberto; Ye, Yufang; Heygster, Georg; Lavergne, Thomas; Aaboe, Signe; Girard Ardhuin, Fanny.
A new algorithm for estimating sea ice age (SIA) distribution based on the Eulerian advection scheme is presented. The advection scheme accounts for the observed divergence or convergence and freezing or melting of sea ice and predicts consequent generation or loss of new ice. The algorithm uses daily gridded sea ice drift and sea ice concentration products from the Ocean and Sea Ice Satellite Application Facility. The major advantage of the new algorithm is the ability to generate individual ice age fractions in each pixel of the output product or, in other words, to provide a frequency distribution of the ice age allowing to apply mean, median, weighted average or other statistical measures. Comparison with the National Snow and Ice Data Center SIA...

Autores: Leon, Pierre; Roland, Francois; Brignone, Lorenzo; Opderbecke, Jan; Greer, Jennifer; Khalighi, M. A.; Hamza, Tasnim; Bourennane, S.; Bigand, M.
Silicon Photomultipliers (SiPMs) have recently been recognized as an interesting alternative to photomultiplier tubes (PMTs) thanks to their high sensitivity and time resolution. They can closely approach quantum-limited sensitivity in the detection of weak optical signals. Ifremer (French Research Institute for Exploitation of the Sea) and Institut Fresnel research lab have been investigating appropriate alternative solutions for PMTs in the context of underwater optical communications, and have for the first time used these new photodetector components for signal detection. A novel prototype of an optical modem based on SiPM receivers was realized with support from Osean SAS Co., a French instrumentation company. A number of lab experiments and sea...

A non-linear second-order stochastic model of ocean surface waves
Provedor de dados: 5
Autores: Joelson, M; Ramamonjiarisoa, A.
This paper deals first with the mathematical formulation of a non-linear second-order stochastic model of free irrotational ocean surface wave on deep water. Then, the case of wave motion of zero bandwidth is treated to illustrate the model. On the basis of the usual hydrodynamic equations, the formulation is made by successive applications of the harmonic decomposition and the so-called Wiener-Hermite functional series expansion of random functions. This procedure yields the kernels equations. These kernels allow to obtain the random surface wave fields from the Wiener set of elementary random processes. For the particular case cited above, as expected, the second-order non-linearity results in the generation of a second harmonic component of the...

A non-linear software sensor to monitor the internal nitrogen quota of phytoplanktonic cells
Provedor de dados: 5
Autores: Bernard, O; Sciandra, A; Sallet, G.
New techniques - called software sensors - issued from the non-linear automatic control field and initially developed for non-linear chemical systems have been applied to a continuous culture of phytoplankton. A software sensor (or 'observer') combines an analytical differential equation based model and partial measurements of the system in order to estimate the non-measured state variables. It filters data and estimates the actual state of living systems, models of which are often rough approximations. The efficiency of this approach is illustrated with a nitrate-limited chemostat experiment with the chlorophyceae Dunaliella tertiolecta performed in a computer controlled fluctuating environment.

A non-linear viscoelastic viscoplastic model for the behaviour of polyester fibres
Provedor de dados: 5
Autores: Chailleux, Emmanuel; Davies, Peter.
In this study the macroscopic analysis proposed by Schapery has been applied to model the non-linear viscoelastic and viscoplastic behaviour of polyester fibres. First, a special non-contact extensometry method has been developed in order to measure the fibre response without affecting the behaviour of these extremely anisotropic fibres. An accelerated identification method has then been developed. This enables a unique and independent set of parameters to be determined, which separate the reversible and non-reversible mechanisms responsible for measured strains. The model prediction for an arbitrary loading sequence corresponds closely to the measured strains. The model has been applied here at the yarn level but can equally well be used to predict rope...

Building chronological frameworks for proxy sequences spanning 130-60 ka b2k is plagued by difficulties and uncertainties. Recent developments in the North Atlantic region, however, affirm the potential offered by tephrochronology and specifically the search for cryptotephra. Here we review the potential offered by tephrostratigraphy for sequences spanning 130-60 ka b2k. We combine newly identified cryptotephra deposits from the NGRIP ice-core and a marine core from the Iceland Basin with previously published data from the ice and marine realms to construct the first tephrostratigraphical framework for this time-interval. Forty-three tephra or cryptotephra deposits are incorporated into this framework; twenty three tephra deposits are found in the...

A note on progress in the bioeconomic modelling of fishing activity in the North Sea
Provedor de dados: 5
Autores: Catanzano, Joseph; Cunningham, S.
Over the relatively recent past, bioeconomic modelling has advanced by  integrating major theoretical and analytical progress made in both economic and biological modelling. The movements from static towards dynamic models and from global towards analytical models were the first steps in this advance. More recently, research has turned towards veritable optimisation models incorporating risk, asymmetrical information, and chaotic and multiple equilibria. Attempts to validate such models have been based on case studies of more and more homogenous fisheries (jesmall numbers of stocks and exploitation systems) so that the objective function is quite explicit and limited. This change of emphasis has occurred however without a re-consideration of the aim of the...

A note on the direct injection of turbulence by breaking waves
Provedor de dados: 5
Autores: Rascle, Nicolas; Chapron, Bertrand; Ardhuin, Fabrice; Soloviev, Alexander.
We investigate the turbulence induced by wave-breaking at the ocean surface. Two recent models use a mechanism of direct depth injection of turbulent kinetic energy (TKE) by breaking waves. Those models aim to reproduce the near-surface mean and turbulent properties, in particular the TKE dissipation rates. Of critical importance are the injection depth of each breaking wave and the size distribution of those breaking waves. The models by Sullivan et al. (2007) and by Kudryavtsev et al. (2008) have very different parameterizations, and those differences are reviewed here and compared to available observations. Using realistic parameterizations in these models leads to TKE injections too shallow to compare to observations, in particular for developed seas....

Background Schistosomiasis is the second-most widespread tropical parasitic disease after malaria. Various research strategies and treatment programs for achieving the objective of eradicating schistosomiasis within a decade have been recommended and supported by the World Health Organization. One of these approaches is based on the control of snail vectors in endemic areas. Previous field studies have shown that competitor or predator introduction can reduce snail numbers, but no systematic investigation has ever been conducted to identify snail microbial pathogens and evaluate their molluscicidal effects. Methodology/Principal findings In populations of Biomphalaria glabrata snails experiencing high mortalities, white nodules were visible on snail...

A novel duplex qPCR assay for stepwise detection of multiple Perkinsea protistan infections of amphibian tissues
Provedor de dados: 5
Autores: Smilansky, Vanessa; Chambouvet, Aurelie; Reeves, Mari; Richards, Thomas A.; Milner, David S.
Alveolate protists within the phylum Perkinsea have been found to infect amphibians across a broad taxonomic and geographic range. Phylogenetic analysis has suggested the existence of two clades of amphibian Perkinsea: a putatively non-pathogenic clade linked to asymptomatic infections of tadpoles in Africa, Europe and South America, and a putatively pathogenic clade linked to disease and mass mortality events of tadpoles in North America. Here, we describe the development of a duplex TaqMan qPCR assay to detect and discriminate between rDNA sequences from both clades of Perkinsea in amphibian tissues. The assay uses a single primer pair to target an 18S small subunit (SSU) ribosomal RNA (rRNA) gene region shared between the two clades, and two...

A novel index based on planktonic copepod reproductive traits as a tool for marine ecotoxicology studies
Provedor de dados: 5
Autores: Hussain, Mohamed Bakr; Laabir, Mohamed; Yahia, Mohamed Nejib Daly.
Copepods are excellent bioindicators of climate change and ecosystem pollution in anthropized coastal waters. This work reviewed the results of previous studies examining changes in egg production rate (EPR), hatching success (HS), and nauplius survival rate (NSR) in natural conditions and in the presence of pollutants, including heavy metals and organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs). At high concentrations, cadmium and silver induce an increase in EPR in the copepods Acartia tonsa and Acartia hudsonica, while exposure to mercury decreases EPR in adults by 50%. All three metals affect HS, with mercury inducing a stronger effect than cadmium and silver. Cadmium affects reproductive...

Multi-biomarker approaches are used to assess ecosystem health and identify impacts of environmental stress on organisms. However, exploration of large datasets by environmental managers represents a major challenge for regulatory application of this tool. Several integrative tools were developed to summarize biomarker responses. The aim of the present paper is to update calculation of the "Integrated Biological Response" (IBR) described by Beliaeff and Burgeot (Environ Toxicol Chem 21:1316-1322, 2002) to avoid weaknesses of this integrative tool. In the present paper, a novel index named "Integrated Biological Responses version 2" based on the reference deviation concept is presented. It allows a clear discrimination of sampling sites as for the IBR, but...

Pseudomonasguezennei biovar. tikehau was isolated from a microbial mat on the atoll of Tikehau in French Polynesia, and is able to synthesize medium chain length poly-beta-hydroxyalkanaote copolymers when grown on coprah oil. A two-step cultivation process was used and the biosynthesis of PHAs was followed along 52 h by regular culture sampling. The polyester was purified from freeze-dried cells and analysed by nuclear magnetic resonance (NMR), Fourier transform infra red (FTIR), and gas chromatography mass spectrometries. The copolyester produced by P. guezennei biovar. tikehau from coprah oil mainly consisted of saturated monomers, i.e. 3-hydroxyoctanoate (3HO) and 3-hydroxydecanoate (3HD), and the monomeric composition of the polyester did not change...

A novel method for diagnosing seasonal to inter-annual surface ocean carbon dynamics from bottle data using neural networks
Provedor de dados: 5
Autores: Sasse, T. P.; Mcneil, B. I.; Abramowitz, Ag.
The ocean's role in modulating the observed 1–7 Pg C yr−1 inter-annual variability in atmospheric CO2 growth rate is an important, but poorly constrained process due to current spatio-temporal limitations in ocean carbon measurements. Here, we investigate and develop a non-linear empirical approach to predict inorganic CO2 concentrations (total carbon dioxide (CT) and total alkalinity (AT)) in the global ocean mixed layer from hydrographic properties (temperature, salinity, dissolved oxygen and nutrients). The benefit of this approach is that once the empirical relationship is established, it can be applied to hydrographic datasets that have better spatio-temporal coverage, and therefore provide an additional constraint to diagnose ocean carbon dynamics...

A novel probabilistic forecast system predicting anomalously warm 2018-2022 reinforcing the long-term global warming trend
Provedor de dados: 5
Autores: Sevellec, Florian; Drijfhout, Sybren S.
In a changing climate, there is an ever-increasing societal demand for accurate and reliable interannual predictions. Accurate and reliable interannual predictions of global temperatures are key for determining the regional climate change impacts that scale with global temperature, such as precipitation extremes, severe droughts, or intense hurricane activity, for instance. However, the chaotic nature of the climate system limits prediction accuracy on such timescales. Here we develop a novel method to predict global-mean surface air temperature and sea surface temperature, based on transfer operators, which allows, by-design, probabilistic forecasts. The prediction accuracy is equivalent to operational forecasts and its reliability is high. The post-1998...

Autores: Mesiet Cladiere, L; Norais, Cédric; Kuhn, Joelle; Briffotaux, Julien; Sloostra, Jerry W.; Ferrari, Elena; Hubscher, Ulrich; Flament, Didier; Myllykallio, Hannu.
During DNA replication and repair, many proteins bind to and dissociate in a highly specific and ordered manner from proliferating cell nuclear antigen (PCNA). We describe a combined approach of in silico searches at the genome level and combinatorial peptide synthesis to investigate the binding properties of hundreds of short PCNA-interacting peptides (PIP-peptides) to archaeal and eukaryal PCNAs. Biological relevance of our combined approach was demonstrated by identification an inactive complex of Pyrococcus abyssi ribonuclease HII with PCNA. Furthermore we show that PIP-peptides interact with PCNA largely in a sequence independent manner. Our experimental approach also identified many so far unidentified PCNA interacting peptides in a number of human...

A novel tracer technique to quantify the atmospheric flux of trace elements to remote ocean regions
Provedor de dados: 5
Autores: Kadko, David; Landing, William M.; Shelley, Rachel.
Atmospheric input into the global ocean constitutes an important budgetary component of numerous chemical species and plays a key role in controlling biogeochemical processes in the ocean. Assessment of this input is difficult, however, because measurements of deposition rates to the ocean, particularly in remote areas, are rare and susceptible to problems of temporal and spatial variability. While the collection and analysis of aerosol samples is somewhat routine, the chemical concentration data collected from ship board or land-based aerosol samplers in and of themselves cannot yield the deposition flux of trace elements; a method is required to transform concentration measurements into flux. The ability to derive the atmospheric flux of Be-7 from its...

Autores: Mnassri, Ilyes; Le Touze, David; Vincent, Benoit; Alessandrini, Bertrand.
The present work investigates an application-oriented issue in the marine and fisheries researches domain. However much trawl structure codes that simulate dynamic behavior of submerged nets, in continuous interaction with surrounded ocean water, still need more accuracy and precision due to the fact that the sea water is mainly considered as a fluid with a uniform velocity and intensity, and so the effects of small turbulence rates were neglected. When this little inaccuracy occurs in the first step of the net displacement prediction, a large error could manifests in the form of the simulated net, and as consequence, drag forces wrongly estimated. In the purpose to overcome the lack of data information exchange during the fluid structure interaction, a co...

A numerical model for free infragravity waves: Definition and validation at regional and global scales
Provedor de dados: 5
Autores: Ardhuin, Fabrice; Rawat, Arshad; Aucan, Jerome.
The spectral wave model WAVEWATCH III is extended from the windsea and swell band to lower frequencies, in order to represent free waves in the infragravity (IG) wave band. This extension is based on an empirical source of IG energy, which is defined along shorelines from the significant wave height and a mean period. The empirical proportionality factor is found to reproduce accurately the variations of free IG wave energy in coastal areas, where it was calibrated, and also has a good skill at global scales. In the open ocean, the model is particularly verified for frequencies in the range 5 to 14 mHz for which ocean bottom records are sensitive to the IG signal. The model captures between 30% and 80% of the variance in IG wave heights, depending on...

Autores: Ardhuin, Fabrice; Lavanant, Thibaut; Obrebski, Mathias; Marie, Louis; Royer, Jean-yves; D'Eu, Jean-francois; Howe, Bruce M.; Lukas, Roger; Aucan, Jerome.
The generation of ultra-low frequency acoustic noise (0.1 to 1 Hz) by the nonlinear interaction of ocean surface gravity waves is well established. More controversial are the quantitative theories that attempt to predict the recorded noise levels and their variability. Here a single theoretical framework is used to predict the noise level associated with propagating pseudo-Rayleigh modes and evanescent acoustic-gravity modes. The latter are dominant only within 200 m from the sea surface, in shallow or deep water. At depths larger than 500 m, the comparison of a numerical noise model with hydrophone records from two open-ocean sites near Hawaii and the Kerguelen islands reveal: (a) Deep ocean acoustic noise at frequencies 0.1 to 1 Hz is consistent with the...

Autores: Ndoye, S; Capet, Xavier; Estrade, Philippe; Machu, Eric; Kounta, L; Sow, B; Diakhate, M; Gayet, At.
The regional ocean circulation along the Southern Senegal shelf is studied using a numerical model for varying forcing fields during the upwelling season (November-May). The main objective is to study the shelf circulation of the marine environment in the Southern Senegal Upwelling Shelf (SSUS), the Lagrangian pathways by which waters are transported to the surface in the upwelling tongue and the fate of these waters. Model results are compared with hydrographic measurements during UPSEN2-ECOAO survey and satellite images datasets. The upwelling source waters and also the warm nearshore waters are analyzed, from a Lagrangian point of view, by computing the paths of particles that are passively advected by the regional ocean model velocity field (ROMS).

A numerical modelling study of upwelling filaments off the NW African coast
Provedor de dados: 5
Autores: Stevens, I; Johnson, J.
A fine resolution (1/12degrees x 1/12degrees) primitive equation limited area model is constructed for the region off NW Africa in the eastern North Atlantic to examine the generation of cool upwelling filaments. A seasonal shift in the trade wind pattern leads to coastal upwelling and an equatorward coastal current. The filaments form at four preferred locations along the NW African coast between 25degreesN and 35degreesN, the largest filament being at Cape Ghir. The generation mechanism for the filaments is similar to the one proposed for filaments in the California current system. As a result of baroclinic instability meanders develop on the coastal current and transport cool upwelled water offshore to form the filaments. During the relaxation phase of...

Autores: Huynhthanh, S; Temperville, A.
The turbulent boundary-layer flow over flat rough beds due to a wave or to combined wave-current interaction is studied using a numerical turbulence closure model of K-L type. Different cases of modelling are discussed and illustrated by numerical examples. The model was run for a wide range of parameters of wave, current, bed roughness and angle of interaction. The curves of dimensionless mean and maximum bed shear stresses obtained present the non-linearity of the wave-current interaction. The parameterization of results is realized in order to facilitate the incorporation of bed shear stresses into coastal morphodynamic models.

A numerical scheme for coastal morphodynamic modelling on unstructured grids
Provedor de dados: 5
Autores: Guerin, Thomas; Bertin, Xavier; Dodet, Guillaume.
Over the last decade, modelling systems based on unstructured grids have been appearing increasingly attractive to investigate the dynamics of coastal zones. However, the resolution of the sediment continuity equation to simulate bed evolution is a complex problem which often leads to the development of numerical oscillations. To overcome this problem, addition of artificial diffusion or bathymetric filters are commonly employed methods, although these techniques can potentially over-smooth the bathymetry. This study aims to present a numerical scheme based on the Weighted Essentially Non-Oscillatory (WENO) formalism to solve the bed continuity equation on unstructured grids in a finite volume formulation. The new solution is compared against a classical...

A numerical study of baroclinic instability at large supercriticality
Provedor de dados: 5
Autores: Klein, Patrice; Pedlosky, J.
A series of numerical integrations of the two-layer quasi-geostrophic model were carried out to investigate the nonlinear dynamics of baroclinically unstable waves at supercriticalities of O(1). The results extend and are contrasted with the results of weakly nonlinear theory valid only for small supercriticality. Particular attention is paid to that sector of parameter space in which the transition from regular to aperiodic behavior is observed for weakly nonlinear waves. It is found that aperiodic, chaotic behavior extends to parameter domains of higher dissipation as a consequence of finite amplitude effects as the supercriticality increases. Sensitive dependence on parameters remains a hallmark of the system as intervals of chaotic, periodic and steady...

A numerical study of the generation and propagation of internal solitary waves in the Luzon Strait
Provedor de dados: 5
Autores: Cai, Sq; Long, Xm; Gan, Zj.
A new composite model, which consists of a generation model of the internal tides and a regularized long wave propagation model, is presented to study the generation and evolution of internal solitary waves in the sill strait. Internal bores in the sill strait are first simulated by the generation model. and then the internal tidal field outside of the sill region is given as input for the propagation model. Numerical experiments are carried out to Study the imposing tide, depth profile. channel width and shoaling effect, etc., on the generation and evolution of internal solitary waves. It is shown that only when the amplitude of internal tide at the forcing boundary of the propagation model is large enough that a train of internal solitary waves would be...

A numerical study of the nonlinear-interaction of hurricane-camille with the gulf-of-mexico loop current
Provedor de dados: 5
Autores: Ly, Ln; Kantha, Lh.
A three-dimensional, primitive equation, ocean general circulation model is used to study the response of the Gulf of Mexico to Hurricane Camille (1969). The free-surface dynamics and the mixed-layer features are included in the model. The numerical model incorporates the realistic coastline and bottom topography. The sigma coordinate model has eighteen levels in the vertical and 0.2-degrees x 0.2-degrees horizontal resolution for the entire gulf. The study focuses on nonlinear interaction between hurricane induced currents and the Loop Current. The numerical simulations show that there is a strong nonlinear interaction between the hurricane and the Loop Current in the southern and central parts of the eastern gulf. The surface currents due to nonlinear...

A numerical study of tropical cyclone-induced sediment dynamics on the Australian North West Shelf
Provedor de dados: 5
Autores: Dufois, Francois; Lowe, Ryan J.; Rayson, Matthew D.; Branson, Paul M.
Owing to their strong forcing of the ocean surface, tropical cyclones strongly modify the hydrodynamics of Australia's North West Shelf (one of the world's tropical cyclone hotspots), which in turn plays a dominant role in its sediment dynamics. Previous modeling studies have focused on describing the short term sediment dynamics during individual tropical cyclones, but have lacked validation of the responses using field observations. As a consequence, the long term cumulative impact of the tropical cyclones on the residual sediment transport pathways at the shelf scale remains unclear. In this study we apply a sediment transport model over the North West Shelf, validate its performance using an extensive field dataset, and implement a 14 year‐long model...

A numerical study of turbulent processes in the marine upper layers
Provedor de dados: 5
Autores: Klein, Patrice; Coantic, Michel.
A second-order turbulence closure model, similar to Mellor and Yamada's (1974) level-3 model, is implemented. This is used to investigate the role of the different turbulent processes and the resulting dynamical and thermal structures, for oceanic upper layers subjected to a variety of unsteady atmospheric forcings. From the distributions obtained for current and temperature, turbulence levels, the production, transfer and dissipation terms in the turbulent kinetic energy and temperature variance budgets, the physics of the oceanic mixed layer and thermocline can be discussed and comparisons made with the models of Mellor and Durbin (1975), Warn-Varnas and Piacsek (1979) and Kundu (1980) and some experimental data. Most often, shear production and viscous...

Autores: Tanner, A.c.; Herbert, R.a.
One hundred and forty four Gram-negative bacteria, indigenous to the maritime Antarctic environment, together with six reference strains, were examined for ninety four unit characters, including morphology, production of exoenzymes, growth temperature characteristics and ability to utilize various organic carbon sources. The resulting data were analysed using the Ssm and Sj similarity coefficients with the UPGMA algorithm. At a 70% level of similary, 97% of the isolates were included in ten clusters. 50% of the isolates were identified as belonging to the genera Aeromonas/Vibrio ; 22 %, Alcaligenes ; 2%, Pseudomonas ; and 2% Flavobacterium. The remainder could not easily be identifed with bacteria previously described in the Eighth edition of Bergey's...

A one-month study of the zooplankton community at a fixed station in the Ligurian Sea: the potential impact of the species composition on the mineralization of organic matter
Provedor de dados: 5
Autores: Mousseau, L.; Lefevre, D.; Narcy, F.; Nival, P.; Andersen, V.
The cruise project was designed to study temporal variations of the ecosystem during the summer-autumn transition and focused on the part played by zooplankton as top-down controllers, and the relative importance of top-down versus bottom-up controls. Zooplankton should play a key role both in the vertical transfer of particulate organic matter and in the mineralisation of organic matter. Although the importance of species diversity is well recognized, the impact of diversity on carbon fluxes is rarely considered. Trophic roles of zooplankton range from strict herbivory to strict carnivory, with all possible combinations (i.e. omnivory) between these two extremes. Feeding strategies are also very diverse, for example, active predators, passive filter...

Autores: Stoner, Joseph S.; Jennings, Anne; Kristjansdottir, Greta B.; Dunhill, Gita; Andrews, John T.; Hardardottir, Jorunn.
We report the intercalibration of paleomagnetic secular variation (PSV) and radiocarbon dates of two expanded postglacial sediment cores from geographically proximal, but oceanographically and sedimentologically contrasting settings. The objective is to improve relative correlation and chronology over what can be achieved with either method alone. Core MD99-2269 was taken from the Hunafloaall Trough on the north Iceland shelf. Core MD99-2322 was collected from the Kangerlussuaq Trough on the east Greenland margin. Both cores are well dated, with 27 and 20 accelerator mass spectrometry (14)C dates for cores 2269 and 2322, respectively. Paleomagnetic measurements made on u channel samples document a strong, stable, single-component magnetization. The...

A palynological analysis of a marine sediment core in the southern Philippines, provides a detailed regional vegetation and climate history for the West Pacific Warm Pool (WPWP) since the Last Glacial Maximum (LGM). Chronology was determined by a detailed oxygen isotope record. A higher representation of pollen from tropical upper montane rainforest during the LGM indicate that this forest type moved down along elevation, probabaly due to the lowered temperature. During the last deglaciation and the early Holocene, mangroves were more expanded and tropical mid and upper montane rainforests were restricted, suggesting a rising sea-level and temperature increase. Herbaceous pollen and pteridophyte spore records indicate a much drier condition during the LGM...

Amphibians are probably the most vulnerable group to climate change and climate-change associate diseases. This ongoing biodiversity crisis makes it thus imperative to improve the taxonomy of anurans in biodiverse but understudied areas such as Amazonia. In this study, we applied robust integrative taxonomic methods combining genetic (mitochondrial 16S, 12S and COI genes), morphological and environmental data to delimit species of the genus Amazophrynella (Anura: Bufonidae) sampled from throughout their pan-Amazonian distribution. Our study confirms the hypothesis that the species diversity of the genus is grossly underestimated. Our analyses suggest the existence of eighteen linages of which seven are nominal species, three Deep Conspecific Lineages, one...

Globally, vibrios represent an important and well-established group of bacterial foodborne pathogens. The European Commission (EC) mandated the Comite de European Normalisation (CEN) to undertake work to provide validation data for 15 methods in microbiology to support EC legislation. As part of this mandated work programme, merging of ISO/TS 21872–1:2007, which specifies a horizontal method for the detection of V. parahaemolyticus and V. cholerae, and ISO/TS 21872–2:2007, a similar horizontal method for the detection of potentially pathogenic vibrios other than V. cholerae and V. parahaemolyticus) was proposed. Both parts of ISO/TS 21872 utilized classical culture-based isolation techniques coupled with biochemical confirmation steps. The work also...

A parameterization of local and remote tidal mixing

Autores: Lavergne, C.; Vic, Clement; Madec, G; Roquet, F.; Waterhouse, A. F.; Whalen, C. B.; Cuypers, Y.; Bouruet‐aubertot, P.; Ferron, Bruno; Hibiya, T.
Vertical mixing is often regarded as the Achilles' heel of ocean models. In particular, few models include a comprehensive and energy‐constrained parameterization of mixing by internal ocean tides. Here, we present an energy‐conserving mixing scheme which accounts for the local breaking of high‐mode internal tides and the distant dissipation of low‐mode internal tides. The scheme relies on four static two‐dimensional maps of internal tide dissipation, constructed using mode‐by‐mode Lagrangian tracking of energy beams from sources to sinks. Each map is associated with a distinct dissipative process and a corresponding vertical structure. Applied to an observational climatology of stratification, the scheme produces a global three‐dimensional map of...

Identification of relevant social impact indicators for a Social Life Cycle Assessment (SLCA) is still difficult and poorly documented (Jorgensen, et al, 2009). In aquaculture systems, the studies based on social aspects are essentially focused on manpower or on conflicts with other activities . In the PISCEnLit project**, we aim to broaden the vision of social impacts of fish farming systems using a new approach of SLCA. We studied fish farming pond systems in France (Lorraine and Brenne) and Indonesia (Tangkit Baru and Kumpeh Ulu in Sumatra island). In this study, we focused on the choice of the impact categories using the participation of stakeholders (James et al., 2002) by the identification and selection of the relevant social impacts to be assessed....

Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective is to allow different actors to jointly develop scenarios which contain their multiple visions of the future. The method starts from four perspectives: “fisheries management,” “ecosystem,” “ocean climate,” and “global context and governance” for which current status and recent trends are summarized. Contrasted scenarios about possible futures are elaborated...

A partnership between science and industry for a monitoring of anchovy &amp; sardine in the Bay of Biscay: When fishermen are actors of science
Provedor de dados: 5
Autores: Masse, Jacques; Sanchez, Florence; Delaunay, Damien; Robert, J. M.; Petitgas, Pierre.
Anchovy and sardine are small pelagic species occupying similar geographic areas in the Bay of Biscay (North-East Atlantic). Their biomass is strongly dependent on recruitment, making the annual assessment of TAC (Total Allowable Catch) a risky strategy due to uncertainty in predicting the magnitude of recruitment. Monitoring these resources more often and throughout their life cycle could allow management strategies to be adjusted based on observations which indicate the level of recruitment. In order to achieve a more frequent monitoring, an innovative data collection strategy involving a partnership between fishermen and scientists, was developed in 2009 and 2010 called “pilot sentinel surveys”. This paper details the partnership, the information such a...

A pattern-filtering method for the determination of ocean bottom pressure anomalies from GRACE solutions
Provedor de dados: 5
Autores: Boening, C.; Timmermann, R.; Macrander, A.; Schroeter, J.
Comparison of mass anomalies from the Gravity Recovery and Climate Experiment (GRACE) to in-situ ocean bottom pressure (OBP) data is complicated by the fact that GRACE estimates are representative for phenomena with scales of hundreds of km, while OBP measurements are pointwise by nature. Simulations with the Finite Element Sea-ice Ocean Model (FESOM) indicate that on a monthly time scale OBP anomalies are coherent over large areas of complex geometry. A new filtering method for GRACE-derived ocean mass anomalies is obtained by applying these coherence patterns on a regular grid. Time series from OBP recorders all over the world ocean are used for validation. Compared to Gaussian filtering, the pattern-filtering method improves the correlation between...

Provedor de dados: 5
Autores: Conan, Gérard; Roux, Michel; Sibuet, Myriam.
During the 1973 cruise of the BIOGAS deep-sea program, a series of 83 frames showing a high population density of the isocrinid stalked crinoid Diplocrinus (Annacrinus) wyvillethomsoni was obtained from a depth of 1246 m on the bathyal slope of the Bay of Biscay. The spatial distribution of D. wyvillethomsoni appears to be highly aggregated. Mean density is 0.61 m-² with confidence limits determined as 0.53 and 0.69 m-², ranging up to 8 or 10 specimens m-² on a sea floor with pebbles and rocks. D. wyvillethomsoni forms a parabolic filtration fan with its arms strongly recurved into the current.  The distal group of cirri grips pebbles or the sharp upper edges of rocks.

A physical-biogeochemical coupling scheme for modeling marine coastal ecosystems
Provedor de dados: 5
Autores: Filgueira, Ramon; Grant, Jon; Bacher, Cedric; Carreau, Michel.
Ecological modeling of dynamic systems such as marine environments may require detailed spatial resolution when the modeled area is greatly influenced by complex physical circulation. Therefore, the simulation of a marine ecosystem must be underlain by a physical model. However, coupling hydrodynamic and biogeochemical models is not straightforward. This paper presents a modeling technique that can be used to build generic and flexible fully-spatial physical-biogeochemical models to study coastal marine ecosystems using a visual modeling environment (VME). The model core is constructed in Simile, a VME that has the capacity to create multiple instances of submodels that can be interconnected, producing a fully-spatial simulation. The core is designed to...

A physiological and biochemical approach to selecting the ideal diet for Ostrea edulis (L.) broodstock conditioning (part A)
Provedor de dados: 5
Autores: Gonzalez-araya, Ricardo; Queau, Isabelle; Quere, Claudie; Moal, Jeanne; Robert, Rene.
To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1 h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O. edulis were fed any microalgae except T-ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1 and the extent of accumulation depended on the species supplied in the order T. suecica&lt;C. gracilis&lt;S. marinoï. When oysters were fed either...

A Physiologically Structured Equation to Consider Quota Heterogeneity in the Droop Model
Provedor de dados: 5
Autores: Mairet, Francis; Baron, Regis.
The Droop model allows to represent microalgae growth limited by a nutrient, using a cell quota (also referred to as variable-yield) approach. Single-cell measurements have revealed quota heterogeneity in phytoplankton collected from field studies. Such heterogeneity can be due, among other factors, to spatial structure (e.g. in biogeochemical cycles in the ocean, or for photobioreactors connected in series). Nonetheless, quota heterogeneity is generally omitted in modelling studies, using an average quota approach, or included in size-structured or individual-based models. Here, we propose a distributed Droop equation to tackle this problem, considering subpopulation growth -in line with Droop macroscopic view- rather than cell division dynamics. We...

Multivariate techniques allow data sets to be summarised, but are not deslgned to causally model ecological phenomena. The ambiguity of the interpretation results from the ambiguity of the scaling space. The phytosociological method proposed by Grandjouan (1982; These d'etat, Universite Louis Pasteur, Strasbourg) is a general interpretive framework allowing separate consideration of 3 distinct reference spaces. a geographical space to visualise the spatio-temporal distribution of the descriptors, an ecological space showing the effects of the environmental variables on the biological descriptors, and a bio-ethological space showing the statistically meaningful species cornmunities. It is thus possible to define the position of each biological category and...

This is the first benthic delta(18)O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal quality to identify 24 new marine isotope stages in the early Pliocene. We also present a new LR04 age model for the Pliocene- Pleistocene derived from tuning the delta(18)O stack to a simple ice model based on 21 June insolation at 65degreesN. Stacked sedimentation rates provide additional age model constraints to prevent overtuning. Despite a conservative tuning strategy, the LR04 benthic stack exhibits significant coherency with insolation in the...

A Pliocene–Quaternary analogue for ancient epeiric carbonate settings: The Malita intrashelf basin (Bonaparte Basin, northwest Australia)
Provedor de dados: 5
Autores: Courgeon, Simon; Bourget, Julien; Jorry, Stephan.
During the Plio-Quaternary, the Bonaparte Basin is characterized by a very wide (&gt; 600 km, &gt; 370 mi) carbonate platform and 200 km-wide (125 mi-wide) intra-shelf basin (the Malita ISB). Using 3D and 2D seismic data combined with exploration well data, this study characterizes the stratigraphic evolution of the Malita ISB during the last 3.5 million years. Two third-order transgressive sequences can be distinguished. A late Pliocene transgression occurred over an irregular topography resulting from the flexural reactivation of the Malita graben. In the centre of the intra-shelf basin, carbonate aggradation resulted in the formation of isolated carbonate platforms separated by deeper water seaways and inter-platform areas. Wider and more numerous...

A pollution-monitoring pilot study involving contaminant and biomarker measurements in the Seine Estuary, France, using zebra mussels (Dreissena polymorpha)
Provedor de dados: 5
Autores: Minier, Christophe; Abarnou, Alain; Jaouen Madoulet, Agnes; Le Guellec, Anne-marie; Tutundjian, Renaud; Bocquene, Gilles; Leboulenger, François.
Zebra mussel (Dreissena polymorpha) is an invasive species that has proliferated in European and North American rivers and lakes during the last century. In this study, D. polymorpha has been used to provide information on contamination levels and biological effects in the Seine Estuary (France). The bivalves accumulated polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) to a high degree with values reaching 800 ng/g dry weight for PCBs (sum of 20 congeners), and 1,000 ng/g dry weight of PAHs (sum of 14 compounds) in the whole body. These values are among the highest reported of PCBs and, to a lesser extent, of PAHs in other contaminated areas in the world. Toxic equivalent quantities of PCBs and PAHs detected in zebra mussels...

A polygenic hypothesis for sex determination in the European sea bass - Dicentrarchus labrax
Provedor de dados: 5
Autores: Vandeputte, Marc; Dupont Nivet, M; Chavanne, H; Chatain, Beatrice.
Polygenic sex determination, although suspected in several species, is thought to be evolutionarily unstable and has been proven in very few cases. In the European sea bass, temperature is known to influence the sex ratio. We set up a factorial mating, producing 5.893 individuals from 253 full-sib families, all reared in a single batch to avoid any between-families environmental effects. The proportion of females in the offspring was 18.3%, with a large variation between families. Interpreting sex as a threshold trait, the heritability estimate was 0.62 +/- 0.12. The observed distribution of family sex ratios was in accordance with a polygenic model or with a four-sex-factors system with environmental variance and could not be explained by any genetic...

A possible link between gabbros bearing high temperature iddingsite alteration and huge pegmatoid intrusions: The Society Islands, French Polynesia
Provedor de dados: 5
Autores: Clement, Jean-philippe; Caroff, Martial; Dudoignon, Patrick; Launeau, Patrick; Bohn, Marcel; Cotten, Joseph; Blais, Sylvain; Guille, Gérard.
This paper reports new field observations and new petrological, textural and geochemical data on two gabbroic intrusions and one pegmatoid dyke from the French Polynesian islands Maupiti and Bora Bora, respectively. Olivine crystals from the Faataufi and Barque de Hiro gabbros (Maupiti) include High Temperature Iddingsite (HTI), exhibiting three distinct morphological facies. Chemical and crystallographical data performed by electron microprobe, scanning microscope, X-ray diffractometry and Near InfraRed spectroscopy show that HTI results from modifications of olivine structure through intense hydroxylation and Fe-oxidation. The HTI-free 120 m-wide Cloche de Hiro dyke (Bora Bora) exhibits a textural zonation from heterogranular/intergranular gabbro...

The north-western Black Sea shelf is the widest continental shelf of the Black Sea, where the Danube delta/prodelta system includes important records on the Black Sea water level fluctuations. This study integrates newly acquired high-resolution single channel seismic reflection profiles and Calypso piston cores recovered along a transect extending from the Danube delta deep into its deep sea fan. The correlated results provide information on the Late Quaternary architecture of the Danube Black Sea shelf and on the role of global glacio-eustatic fluctuations on the building of the Danube delta/prodelta. The sedimentary sequences in the Black Sea are strongly affected by water level changes. For the whole duration of Late Glacial-Holocene period, the level...

A potential flow based flight simulator for an underwater glider
Provedor de dados: 5
Autores: Phoemsapthawee, Surasak; Le Boulluec, Marc; Laurens, Jean-marc; Deniset, Francois.
Underwater gliders are recent innovative types of autonomous underwater vehicles (AUVs) used in ocean exploration and observation. They adjust their buoyancy to dive and to return to the ocean surface. During the change of altitude, they use the hydrodynamic forces developed by their wings to move forward. Their flights are controlled by changing the position of their centers of gravity and their buoyancy to adjust their trim and heel angles. For better flight control, the understanding of the hydrodynamic behavior and the flight mechanics of the underwater glider is necessary. A 6-DOF motion simulator is coupled with an unsteady potential flow model for this purpose. In some specific cases, the numerical study demonstrates that an inappropriate stabilizer...

A precise search for drastic temperature shifts of the past 40,000 years in southeastern Europe
Provedor de dados: 5
Autores: Menot, Guillemette; Bard, Edouard.
Climatic models simulate abrupt oscillations that are associated, in the North Atlantic, with Dansgaard-Oeschger and Heinrich events. However, the geographic extension of temperature anomalies is largely uncontrolled due to the scarcity of quantitative records of sufficient time resolution on the European continent. Here, we propose, based on a recently developed temperature proxy (TEX86), a reconstruction of millennial-scale temperature variations in a Black Sea sediment archive for the last 40,000 years. Prior to any paleoclimatological interpretations the effects of potential bias, such as seasonality and depth of maximum export production on temperature reconstructions, are considered for the Black Sea. Based on previous work, a tentative method for...

A precursor to the Matuyama-Brunhes reversal in Chinese loess and its palaeomagnetic and stratigraphic significance
Provedor de dados: 5
Autores: Jin, Chunsheng; Liu, Qingsong; Cruz Larrasoana, Juan.
We report high-resolution palaeomagnetic results across the lower part of S8 in the Luochuan area, northwest of China using parallel subsets samples. A palaeomagnetic anomaly with low palaeointensity and disordered magnetic direction was identified similar to 21 ka prior to the MatuyamaBrunhes (MB) polarity reversal, and is consistent with the MB precursor observed from marine sediments and lava flows. This is the first convincing report of the MB precursor in terrestrial material (Chinese loess), which attests the global feature of the MB precursor. Constrained by the stratigraphic position of both the MB polarity reversal and the MB precursor, the loess unit L8 and palaeosol unit S8 of the Chinese loess sequence are undoubtedly tied to the marine isotope...

A preliminary evaluation of matricaria maritimum fibres for polymer reinforcement
Provedor de dados: 5
Autores: Davies, Peter; Bourmaud, A.; Pajot, A.; Baley, C.
This short communication describes results from a preliminary characterization of the dimensions and mechanical properties of matricaria maritimum fibres. The aim is to develop a complementary industrial application of these plants, which are grown along the coast mainly for pharmaceutical use. The fibres are shown to be of small diameter, 5-10 mu m, and tubular in form. Nano-indentation on fibres and tensile tests on fibre bundles provide an indication of the mechanical behaviour of these fibres, which are similar to those of sisal (leaf fibre) and miscanthus (grass fibre), and may be interesting for reinforcement of polymer matrix composites.

A preliminary genetic linkage map for the European flat oyster Ostrea eduli
Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Halley, Chris; Boudry, Pierre; Beaumont, Andy.
The European flat oyster, Ostrea edulis, occurs naturally from Norway to Morocco in the North-Eastern Atlantic and throughout the Mediterranean. The oyster has been a harvested species for at least 6000 years. However, it successively suffered from over harvesting and then from two protozoan diseases during the 1960s and its production has drastically decreased in Europe from that time. Following two generations of selection for tolerance to one of these diseases (bonamiosis), our aim is to optimize this selection with the assistance of molecular markers, that is to say to implement marker-assisted selection. This will enhance the efficiency of selection by reducing the generation time, as the selection on sites cannot be made before the oysters are...

A preliminary genetic linkage map for the European flat oyster Ostrea edulis L.
Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Harley, Crhis; Boudry, Pierre; Heurtebise, Serge; Beaumont, Andy.
The flat oyster Ostrea edulis is the species endemic to European coasts, both Atlantic and Mediterranean. It has been exploited since Roman times, but its aquaculture production decreased from around 20000 tons in the 1950's to 1500 tons today because of two successive diseases due to the intracellular parasites Marteilia refringens and Bonamia ostreae. Since 1985, Ifremer has been undertaking a breeding program to produce families of oysters tolerant to Bonamia. In this context, a further step would be to identify QTLs for resistance to this parasite. Therefore, as a first step a genetic map is now being built. The establishment of a genetic linkage map will provide a foundation for the mapping of QTLs, with the ultimate objective to implement...

A preliminary study of the behaviour and vitality of reseeded juvenile great scallops, of three sizes in three seasons
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Mingant, Christian; Castillo, A.
In order to have a better understanding of recessing in great scallop, Pecten maximus and consequently the causes of mortality at reseeding, this study has monitored, at different seasons, the dispersion and recessing of different sizes of juveniles (about 15, 30 and 45 mm, called small, medium and large) after seeding. Moreover, the aim was to see when small spat (15 mm) could be seeded, and thus reduce the costs of intermediate culture. Three monitoring approaches were used together: (1) continual observations by remote video camera, of a defined area (less than 1 m2) containing 10 scallops from each size group; (2) daily monitoring of behaviour with divers along three bottom lines, with 20 × 1 m2 plots each and nine marked scallops per plot; and (3) the...

A probabilistic approach of flow-balanced network based on Markov chains
Provedor de dados: 5
Autores: Leguerrier, Delphine; Bacher, Cedric; Benoit, Eric; Niquil, Nathalie.
We used Markov chains to assess residence time, first passage time, rare of transfers between compartments, recycling index with a general mathematical formalism. Such a description applies to any flow-balanced system that can be modelled as a series of discrete stages or compartments through which matter flows. We derived a general set of equations from a probabilistic approach and applied them to a food web and a physical system derived from the literature. We therefore analysed preferential pathways of matter and behaviour of these systems and showed how it was possible to build up and exploit indices on the basis of a transition probability matrix describing the network, and to characterize with a generic algorithm: (1) the total indirect relationships...

A Process Study of the Tidal Circulation in the Persian Gulf
Provedor de dados: 5
Autores: Pous, Stephane; Carton, Xavier; Lazure, Pascal.
A homogeneous shallow-water model with free surface is used to model the tidal circulation in the Persian Gulf. The numerical finite-difference model includes harmonic diffusion of horizontal momentum and quadratic bottom friction, it has a 9 km mesh size and it is forced by 7 tidal components at its southern boundary. High precision bathymetric data are used to obtain the bottom topography. The numerical model is run for more than a year. The results are the following: 1) The model accurately reproduces the tidal phase and amplitude observed at 42 tidal gauges in the region. This accuracy is attributed to the presence of the 7 components which are able to interact nonlinearly; 2) The amphidromic points are also well positioned by the model due to a proper...

Autores: Pous, Stephane; Carton, Xavier; Lazure, Pascal.
A shallow-water model, coupled with a three dimensional, hydrostatic ocean model, is used to study the wind induced circulation, and the Shatt-al-Arab river plume expansion, in the Persian Gulf. The models are used in an idealized configuration. The following results are obtained: 1) with northwesterly winds, a double gyre is formed: this gyre is cyclonic in the south and anticyclonic in the north. Southeastward currents flow along the Iranian and Arabian coast where the wind stress at the surface dominates the pressure gradient related to the free surface slope, and conversely in the deeper region of the Gulf; 2) In the eastern part of the Gulf, the cyclonic gyre intensifies, as observed and reported in the literature; 3) For northwesterly winds, the...

Habitat dynamics interacting with species dispersal abilities could generate gradients in species diversity and prevalence of species traits when the latter are associated with species dispersal potential. Using a process‐based model of diversification constrained by a dispersal parameter, we simulated the interplay between reef habitat dynamics during the past 140 million years and dispersal, shaping lineage diversification history and assemblage composition globally. The emerging patterns from the simulations were compared to current prevalence of species traits related to dispersal for 6315 tropical reef fish species. We found a significant spatial congruence between the prevalence of simulated low dispersal values and areas with a large proportion of...

But, no relation was noticed with temperature or salinity during the plantonic stage. These results are discussed. An interesting relationship was found between recruitment and "E.T.P.", an index expressing the drying power of air, taking into account temperature, wind, sunshine and moistness.

Marine mollusk aquaculture has more than doubled over the past twenty years, accounting for over 15% of total aquaculture production in 2016. Infectious disease is one of the main limiting factors to the development of mollusk aquaculture, and the difficulties inherent to combating pathogens through antibiotic therapies or disinfection have led to extensive research on host defense mechanisms and host-pathogen relationships. It has become increasingly clear that characterizing the functional profiles of response to a disease is an essential step in understanding resistance mechanisms and moving towards more effective disease control. The Manila clam, Ruditapes philippinarum, is a main cultured bivalve species of economic importance which is affected by...

Model intercomparison studies in the climate and Earth sciences communities have been crucial to building credibility and coherence for future projections. They have quantified variability among models, spurred model development, contrasted within- and among-model uncertainty, assessed model fits to historical data, and provided ensemble projections of future change under specified scenarios. Given the speed and magnitude of anthropogenic change in the marine environment and the consequent effects on food security, biodiversity, marine industries, and society, the time is ripe for similar comparisons among models of fisheries and marine ecosystems.

A proudman-function expansion of the m2 tide in the mediterranean-sea from satellite altimetry and coastal gauges
Provedor de dados: 5
Autores: Sanchez, Bv; Ray, Rd; Cartwright, De.
An empirical model has been derived for the semidiurnal principal lunar tide M2 in the Mediterranean Sea, excluding the Aegean Sea. The work is primarily an exercise in combining satellite altimeter data with tide-gauge data, through the use of specially constructed spatial basis functions. The tide-gauge data consist of M2 harmonic constants previously derived at 43 chosen coastal locations. The altimeter data consist of approximately two years of Geosat data in the form of collinear differences of sea-surface heights, corrected for orbit error by adjusting long sequences of global data. The tide is expressed as an expansion in Proudman functions - numerically constructed, orthogonal eigenfunctions of the velocity potential. The most important mode is...

A quality estimator of acoustic sounding detection
Provedor de dados: 5
Autores: Lurton, Xavier; Ladroit, Yoann; Augustin, Jean-marie.
Swath sonar bathymetry accuracy depends on the intrinsic performance of acoustic signal processing. We propose here a quality factor, quantifying the accuracy associated with every sounding computation. This descriptor is derived from simple models either for amplitude (variance of the centre-of-gravity instant of a fluctuating bell-shaped envelope) or for interferometric phase (local variance for a number of processed samples). The purpose is to attach to each individual sounding an objective quality level that is sonar independent, and directly applicable in bathymetry processing, either in data editing, or as an input parameter to statistical post-processing. This concept is illustrated by examples from experimental data.

A Quantitative Assessment of the Role of the Parasite Amoebophrya in the Termination of Alexandrium fundyense Blooms within a Small Coastal Embayment
Provedor de dados: 5
Autores: Velo-suarez, Lourdes; Brosnahan, Michael L.; Anderson, Donald M.; Mcgillicuddy, Dennis J., Jr.
Parasitic dinoflagellates of the genus Amoebophrya infect free-living dinoflagellates, some of which can cause harmful algal blooms (HABs). High prevalence of Amoebophrya spp. has been linked to the decline of some HABs in marine systems. The objective of this study was to evaluate the impact of Amoebophrya spp. on the dynamics of dinoflagellate blooms in Salt Pond (MA, USA), particularly the harmful species Alexandrium fundyense. The abundance of Amoebophrya life stages was estimated 3-7 days per week through the full duration of an annual A. fundyense bloom using fluorescence in situ hybridization coupled with tyramide signal amplification (FISH-TSA). More than 20 potential hosts were recorded including Dinophysis spp., Protoperidinium spp. and Gonyaulax...

A quantitative estimate of the function of soft-bottom sheltered coastal areas as essential flatfish nursery habitat
Provedor de dados: 5
Autores: Trimoreau, E.; Archambault, Benoit; Brind'Amour, Anik; Lepage, Mario; Guitton, Jerome; Le Pape, O.
Essential fish habitat suitability (EFHS) models and geographic information system (GIS) were combined to describe nursery habitats for three flatfish species (Solea solea, Pleuronectes platessa, Dicologlossa cuneata) in the Bay of Biscay (Western Europe), using physical parameters known or suspected to influence juvenile flatfish spatial distribution and density (i.e. bathymetry, sediment, estuarine influence and wave exposure). The effects of habitat features on juvenile distribution were first calculated from EFHS models, used to identify the habitats in which juvenile are concentrated. The EFHS model for S. solea confirmed previous findings regarding its preference for shallow soft bottom areas and provided new insights relating to the significant...

A quantitative estimation of the energetic cost of brown ring disease in the Manila clam using Dynamic Energy Budget theory
Provedor de dados: 5
Autores: Flye Sainte Marie, Jonathan; Jean, Fred; Paillard, Christine; Kooijman, Sebastiaan.
Brown ring disease (BRD) in the Manila clam, Ruditapes philippinarum, is a bacterial disease caused by the pathogen Vibrio tapetis. This disease induces the formation of a characteristic brown conchiolin deposit on the inner shell and is associated with a decrease in condition index indicating that the development of the disease affects the energy balance of the clam. A previous study showed that the energy budget of the host was affected by a decrease in filtration activity, and hypothesized that a second way to degrade the energy balance was the increase in maintenance costs associated to the cost of immune response and lesion repair. This paper focusses on this second way of degradation of the energy balance.  A starvation experiment confirmed that the...

A Quantitative Metric to Identify Critical Elements within Seafood Supply Networks

A theoretical basis is required for comparing key features and critical elements in wild fisheries and aquaculture supply chains under a changing climate. Here we develop a new quantitative metric that is analogous to indices used to analyse food-webs and identify key species. The Supply Chain Index (SCI) identifies critical elements as those elements with large throughput rates, as well as greater connectivity. The sum of the scores for a supply chain provides a single metric that roughly captures both the resilience and connectedness of a supply chain. Standardised scores can facilitate cross-comparisons both under current conditions as well as under a changing climate. Identification of key elements along the supply chain may assist in informing...

Autores: Andrews, John T.; Kristjansdottir, Greta B.; Eberl, Dennis D.; Jennings, Anne E.
This paper re-evaluates how well quantitative x-ray diffraction (qXRD) can be used as an exploratory method of the weight percentage (wt%) of volcaniclastic sediment, and to identify tephra events in marine cores. In the widely used RockJock v6 software programme, qXRD tephra and glass standards include the rhyodacite White River tephra (Alaska), a rhyolitic tephra (Hekla-4) and the basaltic Saksunarvatn tephra. Experiments of adding known wt% of tephra to felsic bedrock samples indicated that additions &gt;= 10 wt% are accurately detected, but reliable estimates of lesser amounts are masked by amorphous material produced by milling. Volcaniclastic inputs range between 20 and 50 wt%. Primary tephra events are identified as peaks in residual qXRD glass wt%...

A question of rank: DNA sequences and radula characters reveal a new genus of cone snails (Gastropoda: Conidae)
Provedor de dados: 5
Autores: Puillandre, Nicolas; Tenorio, Manuel J.
Molecular phylogenies of cone snails have revealed that the c. 350 sequenced species are divided into four main lineages, Conus, Conasprella, Californiconus and Profundiconus. In a recent study, minute species (less than 8 mm) were for the first time included in a molecular phylogenetic tree and were shown to correspond to deep lineages, of similar status to the four previously recognized, and sister group to Californiconus. They were attributed to the available generic names Lilliconus and Pseudolilliconus. In this article, we analyse, using morphological (shell and radula) and molecular characters (cox1 gene), several species of minute cone snails, and we conclude that the species considered as Pseudolilliconus in the previous study should actually be...

A random effects population dynamics model based on proportions-at-age and removal data for estimating total mortality
Provedor de dados: 5
Autores: Trenkel, Verena; Bravington, Mark V.; Lorance, Pascal.
Catch curves are widely used to estimate total mortality for exploited marine populations. The usual population dynamics model assumes constant recruitment across years and constant total mortality. We extend this to include annual recruitment and annual total mortality. Recruitment is treated as an uncorrelated random effect, while total mortality is modelled by a random walk. Data requirements are minimal as only proportions-at-age and total catches are needed. We obtain the effective sample size for aggregated proportion-at-age data based on fitting Dirichlet-multinomial distributions to the raw sampling data. Parameter estimation is carried out by approximate likelihood. We use simulations to study parameter estimability and estimation bias of four...

A rapid quantitative fluorescence-based bioassay to study allelochemical interactions from Alexandrium minutum
Provedor de dados: 5
Autores: Long, Marc; Tallec, Kevin; Soudant, Philippe; Lambert, Christophe; Le Grand, Fabienne; Sarthou, Geraldine; Jolley, Dianne; Hegaret, Helene.
Harmful microalgal blooms are a threat to aquatic organisms, ecosystems and human health. Toxic dinoflagellates of the genus Alexandrium are known to produce paralytic shellfish toxins and to release bioactive extracellular compounds (BECs) with potent cytotoxic, hemolytic, ichtyotoxic and allelopathic activity. Negative allelochemical interactions refer to the chemicals that are released by the genus Alexandrium and that induce adverse effects on the physiology of co-occurring protists and predators. Releasing BECs gives the donor a competitive advantage that may help to form dense toxic blooms of phytoplankton. However BECs released by Alexandrium minutum are uncharacterized and it is impossible to quantify them using classical chemical methods....

A new genus, Limatium gen, n., and two new species, L. pagodula sp, n, and L. aureum sp, n. are described, found on outer slopes of barrier reefs and fringing reefs in the South Pacific. They are rare for cerithiids, which typically occur in large populations. The two new species arc represented by 108 specimens sampled over a period of 30 years, only 16 of which were collected alive. Three subadults from the Philippines and Vanuatu likely represent a third species. In addition to their rarity, Limatium species arc atypical for cerithiids in their smooth, polished, honey to golden brown shells with distinctive white fascioles extending suture to suture. The radula presents a unique morphology that does not readily suggest an affinity to any of the...

A Critical Hazard Analysis Rating (CHAR) based on the Hazard Analysis Critical Control Point (HACCP) concept is used to monitor oyster purification in New South Wales (N.S.W.), Australia. Critical areas for assessment include oyster condition, separation of raw and treated oysters, water quality (turbidity, salinity, temperature, aeration, circulation), purification period, flow rate, steriliser efficiency and tank hydraulics. Batch records and product identification are included. Purification supplements a total management program for producing safe oysters. The rating can also be used to endorse oysters produced under industry self-regulatory, quality assurance programs. The four main CHAR areas are operational standards, quality assurance, public health...

A realizable force feedback-feedforward control loop for a piston wave absorber
Provedor de dados: 5
Autores: Maisondieu, Christophe; Clément, Alain.
We consider the problem of the absorption of 2D water waves by the horizontal motions of a vertical plane in response to the hydrodynamical force it experiences. The solution of this problem is straightforward in the frequency domain. Unfortunately, the transposition of the frequency domain solution to the time domain by inverse Fourier transforming leads to a non-causal impulse response function. Thus it cannot be used just as it is, neither as a control loop for physical absorbing devices nor as a non radiating boundary condition (NRBC) in numerical modeling. In this paper, we propose a method to derive causal approximations of this ideal controller. Two time-domain absorbing relations are proposed, differing in whether or not one knows a dominant...

The Momareto cruise was held from August 6 to September 6, 2006 on the new French oceanographic vessel Pourquoi pas? The ROV Victor 6000 visited three vent fields, ranging from 850m to 2300m, on the Mid-Atlantic Ridge. The scientific objective of the cruise was to study the spatial and temporal dynamics of hydrothermal communities colonizing these active vent sites. Aside scientific and technological objectives, one of the major goals of this cruise was to share the excitement of our science with the public. For this, the results of the project were shared through different media. The most challenging and exciting communication event remains the real-time transmission of images acquired by the ROV Victor at 1700m depth to a 250 person audience on land.

A reappraisal of the vital effect in cultured benthic foraminifer Bulimina marginata on Mg/Ca values: assessing temperature uncertainty relationships
Provedor de dados: 5
Autores: Wit, J. C.; De Nooijer, L. J.; Barras, C.; Jorissen, F. J.; Reichart, G. J.
The reconstruction of past temperatures is often achieved through measuring the Mg/Ca value of foraminiferal test carbonate. The diversity in foraminiferal Mg/Ca-temperature calibrations suggests that there is also a biological control on this proxy. This study presents a new Mg/Ca-temperature calibration for the benthic foraminifer Bulimina marginata, based on cultures under a range of temperatures (4-14 degrees C). Measured Mg/Ca values for B. marginata correlate with temperature (Mg/Ca = (1.10+/-0.10) e((0.045+/-0.009)) T, R-2 = 0.28 p &lt; 0.01). The inter-individual variability is, however, also significant (standard deviation is 10-35% of the average). Before applying this or any calibration, the effect of the inter-individual variability on the...

Autores: Stevens, Samuel W.; Johnson, Rodney J.; Maze, Guillaume; Bates, Nicholas R.
As a manifestation of mixing dynamics in the upper ocean, interannual and decadal variability of subtropical mode water (STMW) properties in the North Atlantic Ocean provides a valuable insight into ocean–atmosphere interaction in a changing climate. Here, we use hydrographic data from the Bermuda Atlantic Time-Series Study and Hydrostation S sites near Bermuda, as well as various ocean reanalysis products, to evaluate the modern variability of STMW properties. Our study finds an 86–93% loss of STMW thickness at these sites between 2010 and 2018 and a comparable loss throughout the western subtropical gyre, culminating in the weakest STMW pentad on record. We correlate this decline with a reduction in the annual outcropping volume and northward excursions...

Modern instruments together with the use of standard reference materials have improved the accuracy and long-term reproducibility of the analysis of nutrients (ammonium, nitrate, nitrite, phosphate and silicate) in sea water using segmented-flow analysis, so that errors arising from matrix effects become more significant. Colorimetric detectors with bubble-through flowcells have become widely used for seawater analysis in recent years and their associated matrix effects are described. A re-examination of all categories of matrix effects, whose main origin is salinity, was thus undertaken to assess how much they are liable to alter the data. Interferences were classified into four types, each of which was examined in order to show its influence on the...

Autores: Friocourt, Yann; Levier, Bruno; Speich, Sabrina; Blanke, Bruno; Drijfhout, S.
The seasonal circulation along the northern Iberian Peninsula and in the Bay of Biscay is investigated by means of a regional ocean model. In particular, the modeled velocities and tracers are compared to available observations and used to hypothesize what the circulation may look like in areas where the density of observations is scarcer. Despite a few biases in the thermohaline properties of some water masses, the model is able to represent the various water masses present in the region in an acceptable way. In particular, the density and depth ranges of most water masses are in good agreement with observed ranges. Similarly, the circulation schemes compare generally well with observations, both in annual mean as for the seasonal features. The model...

A regionally scalable habitat typology for assessing benthic habitats and fish communities: Application to New Caledonia reefs and lagoons
Provedor de dados: 5
Autores: Pelletier, Dominique; Selmaoui‐folcher, Nazha; Bockel, Thomas; Schohn, Thomas.
Scalable assessments of biodiversity are required to successfully and adaptively manage coastal ecosystems. Assessments must account for habitat variations at multiple spatial scales, including the small scales (&lt;100 m) at which biotic and abiotic habitat components structure the distribution of fauna, including fishes. Associated challenges include achieving consistent habitat descriptions and upscaling from in situ‐monitored stations to larger scales. We developed a methodology for (a) determining habitat types consistent across scales within large management units, (b) characterizing heterogeneities within each habitat, and (c) predicting habitat from new survey data. It relies on clustering techniques and supervised classification rules and was...

Understanding of antimicrobial defence mechanisms of penaeid shrimp should help in the design of efficient strategies for the management and disease control in aquaculture. In this study, we have specifically analysed the expression in circulating hemocytes of antimicrobial peptides (AMPs) encoding genes, such as PEN2 and PEN3, ALF, crustin, lysozyme and a putative cysteine-rich peptide. We evidenced a relationship between the level of expression of some AMPs and the successful response of the shrimp, Litopenaeus stylirostris, to circumvent a pathogenic Vibrio penaeicida infection. Additionally, significant differences in some AMP transcript amounts are evidenced between control, non-selected shrimp line and the third generation breeding of shrimp selected...

A relationship between deep-sea benthic oxygen demand and oceanic primary productivity
Provedor de dados: 5
Autores: Christensen, Jp.
A diagenetic model of porewater O-2 was used to examine the relationship between organic carbon flux to the sediments and benthic oxygen demand (BOD). The model predicted that the organic carbon influx to sediments balances BOD as long as sediments are oxygenated. The critical rate occurs when O-2 at infinite depth disappears. With influxes exceeding the critical rate, the O-2 flux into the sediments via molecular diffusion can not consume all incoming organic matter, and anaerobic conditions result in BOD underestimating the carbon influx. Given that low rates of deep-sea BOD approximate the carbon influx below 9 g.C.m(-2).y(-1), a significant multilinear regression was found between published BOD, primary productivity (P-p, both in g.C.m(-2).y(-1))(,)...

A relative paleointensity record of the geomagnetic field since 1.6 Ma from the North Pacific

Autores: Yamazaki, Toshitsugu; Kanamatsu, Toshiya.
A paleomagnetic study was conducted on a sediment core KR0310-PC1 taken from the central North Pacific in order to obtain a relative paleointensity record in the Matuyama chron from this region. The core reached to about 1.6 Ma. The age control is based on the correlation of the S ratio (S-0.1T) variations with a global oxygen-isotope stack. Isothermal remanent magnetization (IRM) was used as the normalizer of the relative paleointensity estimation; anhysteretic remanent magnetization (ARM) was not adopted because ARM is sensitive to magnetostatic interaction among magnetic particles, which is evidenced in these sediments by an inverse correlation between the ratio of ARM to saturation IRM (SIRM) and SIRM without significant magnetic grain-size changes....

Development of global ocean observing capacity for the biological EOVs is on the cusp of a step-change. Current capacity to automate data collection and processing and to integrate the resulting data streams with complementary data, openly available as FAIR data, is certain to dramatically increase the amount and quality of information and knowledge available to scientists and decision makers into the future. There is little doubt that scientists will continue to expand their understanding of what lives in the ocean, where it lives and how it is changing. However, whether this expanding information stream will inform policy and management or be incorporated into indicators for national reporting is more uncertain. Coordinated data collection including open...

A restricted fishing area as a tool for fisheries management: Example of the Capbreton canyon,southern Bay of Biscay
Provedor de dados: 5
Autores: Sanchez, Florence; Morandeau, Gilles; Bru, Noelle; Lissardy, Muriel.
Marine Protected Areas (MPAs) are generally considered as one of the most important tools, among the many regulations, designed to preserve marine resources as well as enhance fisheries. In the southern Bay of Biscay, local French fishermen requested creation of a restricted area to help settle disputes between the various métiers operating there. This restricted area, which lies mainly in French waters, covers part of a deep submarine canyon off the French and Spanish coasts, known to have a large population of mature hake. This study aims to better understand the effects of a restricted area upon French fleets operating there, particularly upon three main métiers – longliners, gillnetters and trawlers. The study area includes three ICES statistical...

A retrospective analysis of the effects of adopting individual transferable quotas in the Tasmanian red rock lobster, Jasus edwardsii, fishery
Provedor de dados: 5
Autores: Hamon, Katell; Thebaud, Olivier; Frusher, Stewart; Little, L. Richard.
Individual transferable quotas (ITQ) were implemented in the Tasmanian red rock lobster fishery in 1998 and ten years later we assessed the impacts on the fishery. Particular attention was devoted to investigating the performances of the fishery with regard to three features identified as major impacts in the literature: rationalization of the fishing fleet, change in fishing strategy in order to maximise the fisher's profit and concentration of fishing rights and activity. On average, the fishery reacted as expected and reached its objective in terms of reconstruction of the biomass, but the overall assessment in terms of resulting profitability is not very conclusive. There is no evidence of decrease of the profitability over the period of the study but...

A reverse taxonomic approach to assess macrofaunal distribution patterns in abyssal Pacific polymetallic nodule fields
Provedor de dados: 5
Autores: Janssen, Annika; Kaiser, Stefanie; Meissner, Karin; Brenke, Nils; Menot, Lenaick; Martinez Arbizu, Pedro.
Heightened interest in the exploitation of deep seafloor minerals is raising questions on the consequences for the resident fauna. Assessing species ranges and determination of processes underlying current species distributions are prerequisites to conservation planning and predicting faunal responses to changing environmental conditions. The abyssal central Pacific nodule belt, located between the Clarion and Clipperton Fracture Zones (CCZ), is an area prospected for mining of polymetallic nodules. We examined variations in genetic diversity and broad-scale connectivity of isopods and polychaetes across the CCZ. Faunal assemblages were studied from two mining claims (the eastern German and French license areas) located 1300 km apart and influenced by...

A review of capture and post-release mortality of elasmobranchs
Provedor de dados: 5
Autores: Ellis, J. R.; Phillips, S. R. Mccully; Poisson, Francois.
There is a need to better understand the survivorship of discarded fishes, both for commercial stocks and species of conservation concern. Within European waters, the landing obligations that are currently being phased in as part of the European Union's reformed common fisheries policy means that an increasing number of fish stocks, with certain exceptions, should not be discarded unless it can be demonstrated that there is a high probability of survival. This study reviews the various approaches that have been used to examine the discard survival of elasmobranchs, both in terms of at-vessel mortality (AVM) and post-release mortality (PRM), with relevant findings summarized for both the main types of fishing gear used and by taxonomic group. Discard...

A review of Early Weichselian climate (MIS 5d-a) in Europe
Provedor de dados: 5
Autores: Wohlfarth, Barbara.
This report addresses the transition from the last interglacial into the last glacial period in Europe, which corresponds to the time interval between approximately 122,000 and 70,000 years before present. Based on state-of-the-art paleoclimatic and paleoenvironmental information from selected terrestrial, marine and ice core records, questions regarding the magnitude, duration, and cyclicity of early glacial stadial and interstadials are discussed. One of the most important aspects in this respect is the timing of climatic/environmental changes seen in terrestrial, marine, ice core and speleothem records, and most importantly, how and on which basis and by which proxy these climatic shifts are defined. Since correlations between archives are made to...

A review of fishery-independent assessment models, and initial evaluation based on simulated data
Provedor de dados: 5
Autores: Mesnil, Benoit; Cotter, John; Fryer, Rob J.; Needle, Coby L.; Trenkel, Verena.
Large uncertainties in catch data (officially-reported landings and discards) are undermining the ability of scientific organisations to provide valid management advice based on the conventional approach of analytical stock assessments. There is thus an urgent need to consider alternative tools that do not depend on long series of precise age-structured catch data. This paper presents four fishery-independent assessment models developed under the EU project FISBOAT (Fishery Independent Survey Based Operational Assessment Tools). It also reports on rudimentary tests based on simulated data, using the same data sets and protocol as an evaluation study conducted by the US National Research Council in 1997. The survey-based assessment models at hand are able...

A review of image-based tools for automatic fish ageing from otolith features
Provedor de dados: 5
Autores: Carbini, Sebastien; Chessel, Anatole; Benzinou, Abdesslam; Fablet, Ronan; Mahe, Kelig; De Pontual, Helene.
Most of European fish stocks are assessed using age-based models, and otolith interpretation for age estimations costs several million euros annually. In this context, automated ageing systems would provide a mean to 1) standardize ageing, 2) control ageing consistency within and between ageing laboratories 3) build interpreted image data bases ensuring the information conservation and sharing and 4) improve growth studies while reducing the cost of the acquisition of age data. This paper presents a review of different image-based tools for automatic fish ageing from otolith features within the framework of AFISA (EU STREP project on Automated FISh Ageing coordinated by Ifremer). The full automatic ageing process can be divided into three main steps: 1)...

A review of potential impacts of submarine power cables on the marine environment: Knowledge gaps, recommendations and future directions
Provedor de dados: 5
Autores: Taormina, Bastien; Bald, Juan; Want, Andrew; Thouzeau, Gerard; Lejart, Morgane; Desroy, Nicolas; Carlier, Antoine.
Submarine power cables (SPC) have been in use since the mid-19th century, but environmental concerns about them are much more recent. With the development of marine renewable energy technologies, it is vital to understand their potential impacts. The commissioning of SPC may temporarily or permanently impact the marine environment through habitat damage or loss, noise, chemical pollution, heat and electromagnetic field emissions, risk of entanglement, introduction of artificial substrates, and the creation of reserve effects. While growing numbers of scientific publications focus on impacts of the marine energy harnessing devices, data on impacts of associated power connections such as SPC are scarce and knowledge gaps persist. The present study (1)...

Provedor de dados: 5
Autores: Parkes, R. John; Cragg, Barry; Roussel, Erwan; Webster, Gordon; Weightman, Andrew; Sass, Henrik.
A general review of the sub-seafloor biosphere is presented. This includes an update and assessment of prokaryotic cell distributions within marine sediments, current deepest 1922 m, and the impact of this on global sub-seafloor biomass estimates. These global estimates appear relatively robust to different calculation approaches and our updated estimate is 5.39 × 1029 cells, taking into consideration new data from very low organic matter South Pacific Gyre sediments. This is higher than other recent estimates, which is justified as several sediments, such as gas hydrate deposits and oil reservoirs, can have elevated cell concentrations. The proposed relationship between elevated cell concentrations and Milankovitch Cycles in sequential diatom rich layers...

A review of rare and less well known extant marine organic-walled dinoflagellate cyst taxa of the orders Gonyaulacales and Suessiales from the Northern Hemisphere
Provedor de dados: 5
Autores: Limoges, Audrey; Van Nieuwenhove, Nicolas; Head, Martin J.; Mertens, Kenneth; Pospelova, Vera; Rochon, André.
Dinoflagellate resting cysts with rare exception produce the only discrete link between the biology of extant dinoflagellate species and their fossil record. The geological preservability of such cysts allows them to be used for quantitative paleoecological reconstructions, especially in the Quaternary, and for biostratigraphy and the calibration of molecular clocks with the geological record. This contribution reviews and updates the taxonomy of 27 uncommon dinoflagellate cyst species and morphotypes belonging to the orders Gonyaulacales and Suessiales with occurrences in upper Quaternary marine sediments of the Northern Hemisphere. Comparative descriptions and illustrations are provided along with the biological affinity of each taxon where known and...

A review of rare, poorly known, and morphologically problematic extant marine organic-walled dinoflagellate cyst taxa of the orders Gymnodiniales and Peridiniales from the Northern Hemisphere

Dinoflagellates are a major component of the modern plankton. Of the 2192 species of marine free-living dinoflagellates presently described, an increasing number are being shown to produce resting cysts (probably hypnozygotes) within their life cycle. With rare exception, only the resting cysts fossilize, so they are of central importance in tracing the history of dinoflagellates through geological time. Cysts of many of the more common dinoflagellate species have distinctive morphologies allowing their geographic and stratigraphic occurrences to be traced. An ever-increasing number of taxa are also being shown to produce distinctive cysts, potentially increasing our knowledge of the diverse representation of dinoflagellates through time. Here the...

A review of synthetic fiber moorings for marine energy applications
Provedor de dados: 5
Autores: Davies, Peter; Weller, Sam D.; Johanning, Lars; Banfield, Stephen J.
Many marine renewable energy (MRE) conversion systems including wave, floating wind, Ocean Thermal Energy Conversion (OTEC) and some tidal energy devices, are moored in place. The choice of mooring system is critical as it directly affects installation, energy take-off, and long term reliability, and hence has a significant influence on costs. Installation has been estimated to account for 27% of lifetime cost for a tidal turbine [1]. This is an area where the other marine industries, notably offshore oil and gas, have extensive experience, but the high energy regions in which MRE devices are deployed pose particular installation difficulties and operating conditions. There has been a strong movement towards replacing steel with synthetic fiber ropes...

The main objective of the LAgrangian Transport EXperiment (LATEX) project was to study the influence of coastal mesoscale and submesoscale physical processes on circulation dynamics, cross-shelf exchanges, and biogeochemistry in the western continental shelf of the Gulf of Lion, Northwestern Mediterranean Sea. LATEX was a five-year multidisciplinary project based on the combined analysis of numerical model simulations and multi-platform field experiments. The model component included a ten year realistic 3D numerical simulation, with a 1 km hor-izontal resolution over the gulf, nested in a coarser 3 km resolution model. The in situ component involved four cruises, including a large-scale multidisciplinary campaign with two research vessels in 2010. This...

A review of the role of submarine canyons in deep-ocean exchange with the shelf
Provedor de dados: 5
Autores: Allen, S. E.; Durrieu De Madron, X.
Cross shelf-break exchange is limited by the tendency of geostrophic flow to follow bathymetric contours, not cross them. However, small scale topography, such as canyons, can reduce the local lengthscale of the flow and increase the local Rossby number. These higher Rossby numbers mean the flow is no longer purely geostrophic and significant cross-isobath flow can occur. This cross-isobath flow includes both upwelling and downwelling due to wind-driven shelf currents and the strong cascading flows of dense shelf-water into the ocean. Tidal currents usually run primarily parallel to the shelf-break topography. Canyons cut across these flows and thus are often regions of generation of strong baroclinic tides and internal waves. Canyons can also focus...

A.
Silicon (Si) is the second most abundant element in the Earth's crust and is an important nutrient in the ocean. The global Si cycle plays a critical role in regulating primary productivity and carbon cycling on the continents and in the oceans. Development of the analytical tools used to study the sources, sinks, and fluxes of the global Si cycle (e.g., elemental and stable isotope ratio data for Ge, Si, Zn, etc.) have recently led to major advances in our understanding of the mechanisms and processes that constrain the cycling of Si in the modern environment and in the past. Here, we provide background on the geochemical tools that are available for studying the Si cycle and highlight our current understanding of the marine, freshwater and terrestrial...

Autores: Urgeles, Roger; Cattaneo, Antonio; Puig, Pere; Liquete, Camino; De Mol, Ben; Amblas, David; Sultan, Nabil; Trincardi, Fabio.
Most Mediterranean prodeltas show undulated sediment features on the foresets of their Holocene wedges. These features have been described all along the Mediterranean for the last 30 years and interpreted as either soft sediment deformation and incipient landsliding, and more recently, as sediment transport structures. We perform a review and detailed analysis of these undulated sediment features using ultrahigh-resolution seismic and bathymetric data as well as geotechnical information and hydrodynamic time series and hydrographic transects. In this study we show that the characteristics of the sediment undulations (configuration of the reflections down section and between adjacent undulations and overall morphologic characteristics) are incompatible with...

A revised calendar age for the last reconnection of the Black Sea to the global ocean
Provedor de dados: 5
Autores: Soulet, Guillaume; Menot, G.; Lericolais, Gilles; Bard, E.
During the last decade, a debate arose regarding the timing and pattern of the last reconnection of the Black Sea "Lake" with the global ocean. On a geochemical basis, the radiocarbon age of Black Sea "Lake" surface water, during the time of reconnection, was determined to be similar to 8400 C-14 a. BP. Despite the potential bias induced by the hard water effect in lakes, the reconnection age was calibrated without any reservoir age correction, which led to an estimate of similar to 9400 cal a. BR Since knowledge for the actual calendar age has important hydrologic implications that would provide new insights regarding the mechanism of reconnection, determining the actual calendar age for the last reconnection remains important. Based upon modeling...

A revised L-band radio-brightness sensitivity to extreme winds under tropical cyclones: The 5 year SMOS-Storm database
Provedor de dados: 5
Autores: Reul, Nicolas; Chapron, Bertrand; Zabolotskikh, E.; Donlon, C.; Quilfen, Yves; Guimbard, Sebastien; Piolle, Jean-francois.
Five years of SMOS L-band brightness temperature data intercepting a large number of tropical cyclones (TCs) are analyzed. The storm-induced half-power radio-brightness contrast (ΔI) is defined as the difference between the brightness observed at a specific wind force and that for a smooth water surface with the same physical parameters. ΔI can be related to surface wind speed and has been estimated for ~ 300 TCs that intercept with SMOS measurements. ΔI, expressed in a common storm-centric coordinate system, shows that mean brightness contrast monotonically increases with increased storm intensity ranging from ~ 5 K for strong storms to ~ 24 K for the most intense Category 5 TCs. A remarkable feature of the 2D mean ΔI fields and their variability is that...

For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name "blanket-crab". During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the...

Autores: Norman, Md; Hochberg, Fg; Boucher-rodoni, R.
Deep-water trawl surveys on seamounts around New Caledonia yielded 62 specimens of the little-known genus, Scaeurgus. Members of this genus of octopuses typically occur at depths of 200-500 m in temperate and tropical latitudes worldwide. Prior to this study, Scaeurgus was considered to contain one to two species. The new material from New Caledonia contained a surprising diversity of Scaeurgus species from a small area: three distinct new species are described and limited material of a further two taxa is reported. A pygmy member of this genus is reported for the first time. Distributions of these new taxa are consistent with reports of high endemism on the seamount systems in this region. Fifty-eight of the 62 specimens were collected from seamounts,...

Rivers are fascinating ecosystems in which the eco‐evolutionary dynamics of organisms are constrained by particular features, and biologists have developed a wealth of knowledge about freshwater biodiversity patterns. Over the last 10 years, our group used a holistic approach to contribute to this knowledge by focusing on the causes and consequences of intraspecific diversity in rivers. We conducted empirical works on temperate permanent rivers from southern France, and we broadened the scope of our findings using experiments, meta‐analyses, and simulations. We demonstrated that intraspecific (genetic) diversity follows a spatial pattern (downstream increase in diversity) that is repeatable across taxa (from plants to vertebrates) and river systems.

Almost one-third of humanity indeed lives around the Indian Ocean, many in countries dependent on fisheries and rain-fed agriculture that are vulnerable to climate variability and extremes. The Indian Ocean alone has absorbed a quarter of the global oceanic heat uptake over the last two decades and the fate of this heat and its impact on future change is unknown. Climate models project accelerating sea level rise, more frequent extremes in monsoon rainfall, and decreasing oceanic productivity. In view of these new scientific...

The health of the ocean, central to human well-being, has now reached a critical point. Most fish stocks are overexploited, climate change and increased dissolved carbon dioxide are changing ocean chemistry and disrupting species throughout food webs, and the fundamental capacity of the ocean to regulate the climate has been altered. However, key technical, organizational, and conceptual scientific barriers have prevented the identification of policy levers for sustainability and transformative action. Here, we recommend key strategies to address these challenges, including (1) stronger integration of sciences and (2) ocean-observing systems, (3) improved science-policy interfaces, (4) new partnerships supported by (5) a new ocean-climate finance system,...

A robust, multisite Holocene history of drift ice off northern Iceland: implications for North Atlantic climate
Provedor de dados: 5
Autores: Andrews, John T.; Darby, Dennis; Eberle, Dennis; Jennings, Anne E.; Moros, Matthias; Ogilvie, Astrid.
An important indicator of Holocene climate change is provided by evidence for variations in the extent of drift ice. A proxy for drift ice in Iceland waters is provided by the presence of quartz. Quantitative x-ray diffraction analysis of the &lt; 2 mm sediment fraction was undertaken on 16 cores from around Iceland. The quartz weight (wt.)% estimates from each core were integrated into 250-yr intervals between -0.05 and 11.7 cal. ka BP. Median quartz wt.% varied between 0.2 and 3.4 and maximum values ranged between 2.8 and 11.8 wt.%. High values were attained in the early Holocene and minimum values were reached 6 7 cal. ka BP. Quartz wt.% then rose steadily during the late Holocene. Our data exhibit no correlation with counts on haematite-stained quartz...

A role for icebergs in the 8.2 ka climate event
Provedor de dados: 5
Autores: Wiersma, Ane P.; Jongma, Jochem I.
We investigate the potential role of icebergs in the 8.2 ka climate event, using a coupled climate model equipped with an iceberg component. First, we evaluate the effect of a large iceberg discharge originating from the decaying Laurentide ice sheet on ocean circulation, compared to a release of an identical volume of freshwater alone. Our results show that, on top of the freshwater effect, a large iceberg discharge facilitates sea-ice growth as a result of lower sea-surface temperatures induced by latent heat of melting. This causes an 8% increased sea-ice cover, 5% stronger reduction in North Atlantic Deep Water production and 1A degrees C lower temperature in Greenland. Second, we use the model to investigate the effect of a hypothetical two-stage lake...

A sampling strategy and methodology for assessment and monitoring of Mediterranean small-scale fisheries
Provedor de dados: 5
Autores: Farrugio, Henri; Le Corre, Gildas.
In order to reach a quantitative assessment of the Mediterranean small-scale fisheries one of the main problems is to evaluate in space and time the elementary fishing efforts and yields of every component and their corresponding variations. These elements are essential for the evaluation of global production and fishing effort, the monitoring of which is of paramount interest for the study of the fisheries and exploited resource dynamics. This paper presents a methodology based on the statistical principles of so-called "stratified random sampling" which we have developed in an attempt to solve this problem. The collection of data is achieved in the field by a team of investigators which operates within a space-time stratification of the study area. The...

A satellite altimeter model for ocean slick detection - art. no. C04004
Provedor de dados: 5
Autores: Tournadre, Jean; Chapron, Bertrand; Reul, Nicolas; Vandemark, D.
[1] About 5% of Ku-band altimeter ocean data are degraded by the occurrence of high radar return cross sections (sigma(0)), usually called sigma(0) blooms. During blooms, which occur during no or low wind conditions, the mean altimeter waveform can significantly depart from the expected shape. In about 60% of the cases the waveforms are distorted to such an extent that either the range tracker loses lock or the off-nadir angle estimate becomes unrealistic. The analysis of high data rate altimeter waveforms during bloom events reveals the presence of V-shaped patterns similar to the ones observed during rain events. These patterns trace small-scale (i.e., smaller than the altimeter footprint) changes in surface backscatter. Such variations of surface...

Autores: Le Pichon, Xavier; Melguen, M.; Sibuet, Jean-claude.
A schematic model of the evolution of the South Atlantic ocean is proposed to demonstrate the possibilities offered by the Deep Sea Drilling Project within the framework of Plate Tectonics to reconstruct a logical evolution of the history of the ocean basins and their paleoenvironment. The emphasis is put on the methodology available to reconstruct the ocean crust morphology and its sedimentary cover at all stages throughout the opening of the ocean.Paleobathymetric, deep paleo-water-circulation and paleo-sedimentary - facies maps at five different stages of the opening are presented and discussed. The last type of maps are in great part based on a new paleo - Carbonate Compensation Depth Curve for the South Atlantic which is tentatively proposed here....

A seasonal dipolar eddy near Ras Al Hamra (Sea of Oman)
Provedor de dados: 5
Autores: L'Hegaret, Pierre; Lacour, Leo; Carton, Xavier; Roullet, Guillaume; Baraille, Remy; Correard, Stephanie.
Trajectories and hydrological data from two Argo floats indicate that warm and salty water at 200–300-m depths was ejected from the coast of Oman, near Ras al Hamra, in spring 2008, 2011, and 2012. This warm and salty water, Persian Gulf Water (PGW), once ejected from the coast, recirculated cyclonically in the western Sea of Oman, but also flowed eastward along the Iranian and Pakistani coasts. There, it was expelled seaward by mesoscale eddies as shown by other float data. Seasonal maps of salinity were computed from all available Argo floats; they showed that, in spring, PGW is present in the middle and north of the Sea of Oman, contrary to fall, when the salinity maxima lie southeast of Ras al Hadd. The ejection of PGW from Ras al Hamra is related here...

A self-regularising DVM–PSE method for the modelling of diffusion in particle methods
Provedor de dados: 5
Autores: Mycek, Paul; Pinon, Gregory; Germain, Gregory; Rivoalen, Elie.
The modelling of diffusive terms in particle methods is a delicate matter and several models have been proposed in the literature. The Diffusion Velocity Method (DVM) consists in rewriting these terms in an advective way, thus defining a so-called diffusion velocity. In addition to the actual velocity, it is used to compute the particles displacement. On the other hand, the well-known and commonly used Particle Strength Exchange method (PSE) uses an approximation of the Laplacian operator in order to model diffusion. This approximation is based on an exchange of particles strength.  Although DVM is particularly well suited to particle methods since it preserves their Lagrangian aspect, its major drawback stems in the fact that it suffers from severe...

A semi-automated Raman micro-spectroscopy method for morphological and chemical characterizations of microplastic litter
Provedor de dados: 5
Autores: Frere, L.; Paul-pont, I.; Moreau, Julien; Soudant, P.; Lambert, C.; Huvet, Arnaud; Rinnert, Emmanuel.
Every step of microplastic analysis (collection, extraction and characterization) is time-consuming, representing an obstacle to the implementation of large scale monitoring. This study proposes a semi-automated Raman micro-spectroscopy method coupled to static image analysis that allows the screening of a large quantity of microplastic in a time-effective way with minimal machine operator intervention. The method was validated using 103 particles collected at the sea surface spiked with 7 standard plastics: morphological and chemical characterization of particles was performed in &lt; 3 h. The method was then applied to a larger environmental sample (n = 962 particles). The identification rate was 75% and significantly decreased as a function of particle...

A semiempirical model of the normalized radar cross section of the sea surface, 2. Radar modulation transfer function

Autores: Kudryavtsev, V; Hauser, D; Caudal, G; Chapron, Bertrand.
normalized radar cross section (NRCS) over the sea surface. However, these models are not able to correctly reproduce the NRCS in all configurations. In particular, even if they may provide consistent results for vertical transmit and receive (VV) polarization, they fail in horizontal transmit and receive (HH) polarization. In addition, there are still important discrepancies between model and observations of the radar modulation transfer function (MTF), which relates the modulations of the NRCS to the long waves. In this context, we have developed a physical model that takes into account not only the Bragg mechanism but also the non-Bragg scattering associated with radio wave scattering from breaking waves. The same model was built to explain both the...

A semiempirical model of the normalized radar cross-section of the sea surface - 1. Background model
Provedor de dados: 5
Autores: Kudryavtsev, V; Hauser, D; Caudal, G; Chapron, Bertrand.
Multiscale composite models based on the Bragg theory are widely used to study the normalized radar cross-section (NRCS) over the sea surface. However, these models are not able to correctly reproduce the NRCS in all configurations and wind wave conditions. We have developed a physical model that takes into account, not only the Bragg mechanism, but also the non-Bragg scattering mechanism associated with wave breaking. A single model was built to explain on the same physical basis both the background behavior of the NRCS and the wave radar Modulation Transfer Function (MTF) at HH and VV polarization. The NRCS is assumed to be the sum of a Bragg part (two-scale model) and of a non-Bragg part. The description of the sea surface is based on the short wind...

A semi-evolutive filter with partially local correction basis for data assimilation in oceanography
Provedor de dados: 5
Autores: Hoteit, I; Pham, Dt; Blum, J.
A new data assimilation scheme derived from the singular evolutive extended Kalman (Seek) filter is introduced. The novel feature of the new filter is its correction basis which is partially local in the sense that it consists of "global" and "local" vectors, the later obtained from a local empirical orthogonal functions (Eof) analysis. Such an analysis was introduced in order to better represent the local variability of the ocean. This not only significantly reduces the implementation cost but may also improve the representativeness of the correction basis of the filter. The performance of this scheme is evaluated through twin experiments conducted in a realistic setting of the OPA model over the tropical Pacific zone. The results are compared against...

A Sensitivity Analysis of the Impact of Rain on Regional and Global Sea-Air Fluxes of CO2
Provedor de dados: 5
Autores: Ashton, I. G.; Shutler, J. D.; Land, P. E.; Woolf, D. K.; Quartly, G. D.
The global oceans are considered a major sink of atmospheric carbon dioxide (CO2). Rain is known to alter the physical and chemical conditions at the sea surface, and thus influence the transfer of CO2 between the ocean and atmosphere. It can influence gas exchange through enhanced gas transfer velocity, the direct export of carbon from the atmosphere to the ocean, by altering the sea skin temperature, and through surface layer dilution. However, to date, very few studies quantifying these effects on global net sea-air fluxes exist. Here, we include terms for the enhanced gas transfer velocity and the direct export of carbon in calculations of the global net sea-air fluxes, using a 7-year time series of monthly global climate quality satellite remote...

A Shift from Cellular to Humoral Responses Contributes to Innate Immune Memory in the Vector Snail Biomphalaria glabrata

Discoveries made over the past ten years have provided evidence that invertebrate antiparasitic responses may be primed in a sustainable manner, leading to the failure of a secondary encounter with the same pathogen. This phenomenon called "immune priming" or "innate immune memory" was mainly phenomenological. The demonstration of this process remains to be obtained and the underlying mechanisms remain to be discovered and exhaustively tested with rigorous functional and molecular methods, to eliminate all alternative explanations. In order to achieve this ambitious aim, the present study focuses on the Lophotrochozoan snail, Biomphalaria glabrata, in which innate immune memory was recently reported. We provide herein the first evidence that a shift from a...

A shift in the ocean circulation has warmed the subpolar North Atlantic Ocean since 2016

Autores: Desbruyères, Damien; Chafik, Léon; Maze, Guillaume.
The Subpolar North Atlantic is known for rapid reversals of decadal temperature trends, with ramifications encompassing the large-scale meridional overturning and gyre circulations, Arctic heat and mass balances, or extreme continental weather. Here, we combine datasets derived from sustained ocean observing systems (satellite and in situ), idealized observation-based modelling (advection-diffusion of a passive tracer), and a machine learning technique (ocean profile clustering) to document and explain the most-recent and ongoing cooling-to-warming transition of the Subpolar North Atlantic. Following a gradual cooling of the region that was persisting since 2006, a surface-intensified and large-scale warming sharply emerged in 2016 following an ocean...

Autores: Menu, Bruno; Peruzzi, Stefano; Vergnet, Alain; Vidal, Marie-odile; Chatain, Beatrice.
The objective of this study was to develop a rapid and effective method of sexing juvenile sea bass with minimum labour and material. To this end, the gonad squash mount technique was applied along with macroscopic techniques for sexing a large number of experimental fish at the age of 215-275 days post fertilization (p.f.). At this age, 90% of the 3894 fish could be unambiguously sexed by macroscopic examination of their gonads, whereas the remaining proportion was identified using squash mount preparations (10%). The accuracy of the observations was measured up to classical histology procedures. Undifferentiated fish accounted for 0.1% of the total population only. The application of the squash mount technique holds out the prospect of considerable...

A signal of persistent Atlantic multidecadal variability in Arctic sea ice
Provedor de dados: 5
Autores: Miles, Martin W.; Divine, Dmitry V.; Furevik, Tore; Jansen, Eystein; Moros, Matthias; Ogilvie, Astrid E. J.
Satellite data suggest an Arctic sea ice-climate system in rapid transformation, yet its long-term natural modes of variability are poorly known. Here we integrate and synthesize a set of multicentury historical records of Atlantic Arctic sea ice, supplemented with high-resolution paleoproxy records, each reflecting primarily winter/spring sea ice conditions. We establish a signal of pervasive and persistent multidecadal (~60–90 year) fluctuations that is most pronounced in the Greenland Sea and weakens further away. Covariability between sea ice and Atlantic multidecadal variability as represented by the Atlantic Multidecadal Oscillation (AMO) index is evident during the instrumental record, including an abrupt change at the onset of the early twentieth...

We describe here a protocol for the generation of sequence-ready libraries for population epigenomics studies, and the analysis of alignment results. We show that the protocol can be used to monitor chromatin structure changes in populations when exposed to environmental cues. The protocol is a streamlined version of the Assay for transposase accessible chromatin with high-throughput sequencing (ATAC-seq) that provides a positive display of accessible, presumably euchromatic regions. The protocol is straightforward and can be used with small individuals such as daphnia and schistosome worms, and probably many other biological samples of comparable size (~10,000 cells), and it requires little molecular biology handling expertise.

A simple model for the break-up of marine aggregates by turbulent shear
Provedor de dados: 5
Autores: Ruiz, Jean-eric; Izquierdo, A.
A simple model for the break-up, by turbulent shear, of marine aggregates is proposed. Three factors are considered to control the rupture of aggregates of different sizes. First, turbulence exerts stronger shear forces on bigger aggregates. Second, big aggregates are weaker than small ones because their porosity increases. Third, the rate of rupture of an aggregate is considered to be dependent on the point in the aggregate where the rupture takes place. This third factor allows the determination of the size distribution resulting from aggregate break-up. By considering these factors the model predicts the break-up rates of aggregates of different sizes and the aggregates' size-distribution resulting from this break-up. Therefore, the model represents an...

A simple way of avoiding feed wastage in European seabass, Dicentrarchus labrax, under self-feeding conditions
Provedor de dados: 5
Autores: Coves, Denis; Gasset, Eric; Lemarie, Gilles; Dutto, Gilbert.
Self-feeding systems allow fish to freely express feeding activity. A simple rod at the water surface can act as a trigger and provide fish with a way of obtaining pellets from a feeder. Such a rod presented to experienced European seabass, Dicentrarchus labrax, may lead to feed wastage, probably as a result of unintentional fish contacts with the trigger. Trigger protection screens have been designed to prevent fish contacting the trigger by chance, and the efficacy of such screens was tested. Nocturnal and diurnal feed delivery and feed wasted were compared under conditions where the rod was unprotected or protected by semi-cylindrical or cylindrical screens. Tests were conducted using an unrestricted self-feeding regime (reward: 0.2 g pellet per kg of...

A simplified asymptotic theory for ocean surface electromagnetic wave scattering
Provedor de dados: 5
Autores: Mouche, Alexis; Chapron, Bertrand; Reul, Nicolas.
The normalized radar cross-section ( NRCS) expression of the Local Curvature Approximation (LCA-1) is derived to first order. The polarization sensitivity of this model is compared to the Kirchhoff Approximation ( KA), Two-Scale Model (TSM), Small Slope Approximation (SSA-1) and Small Perturbation Method (SPM-1) to first order in the backscattering configuration. Analytical comparisons and numerical simulations show that LCA-1 and TSM could be rewritten with the same formulation and that their polarization sensitivities are comparable. Comparisons with experimental data acquired in C- and Ku-band reveal that the polarization sensitivities of these models are not adequate. However, the NRCS azimuth modulation predicted by LCA-1 is found to be dependent on...

As triggered along the path of moving TCs, very large interior ocean displacements can occur to leave prominent SSH anomalies in the TC wake. Resulting surface depressions can reach.3‐.5 m, depending upon size, translation speed, and ocean stratification conditions. These signatures can be quite persistent, i.e. more than few weeks, to possibly be intercepted...

A simplified model for the baroclinic and barotropic ocean response to moving tropical cyclones: 2. Model and Simulations
Provedor de dados: 5
Autores: Kudryavtsev, Vladimir; Monzikova, Anna; Combot, Clement; Chapron, Bertrand; Reul, Nicolas.
A simplified analytical model is developed to describe the baroclinic and barotropic ocean response to moving Tropical cyclones (TC) and their associated pycnocline erosions. The model builds on classical mixed layer (ML) models and linear models of ocean response to transient events. As suggested, disturbances of the upper ocean stratification caused by the ML development shall not strongly impact the dynamics of baroclinic modes. Accordingly, the baroclinic response can be estimated using the pre‐storm ocean stratification condition. To the contrary, the ML is strongly coupled with these interior motions, through the TC‐induced upwelling response which affects the entrainment velocity. The ML temperature is then strongly dependent on the local...

A simplified wave enhancement criterion for moving extreme events
Provedor de dados: 5
Autores: Kudryavtsev, Vladimir; Golubkin, Pavel; Chapron, Bertrand.
An analytical model is derived to efficiently describe the wave energy distribution along the main transects of a moving extreme weather event. The model essentially builds on a generalization of the self-similar wave growth model and the assumption of a strongly dominant single spectral mode in a given quadrant of the storm. The criterion to anticipate wave enhancement with the generation of trapped abnormal waves defined as inline image, with inline image, inline image, and inline image, radial distance, average sustained wind speed, and translation velocity, respectively. Constants inline image and inline image follow the fetch-law definitions. If forced during a sufficient time scale interval, also defined from this generalized self-similar wave growth...

A simulation framework to evaluate management strategies for Atlantic tunas: a preliminary example based on east Atlantic bluefin
Provedor de dados: 5
Autores: Kell, Laurence T; Fromentin, Jean-marc; Gauthiez, F; Restrepo, Victor.
The Ad Hoc Working Group on the Precautionary Approach (SCRS/99/11) recommended the development of a simulation modelling framework to investigate the performance of stock specific management strategies under a variety of realistic hypothesis about population and fishery dynamics. This paper describes a preliminary simulation model based on East Atlantic bluefin tuna developed using flexible software that allows the implications for management of a variety of plausible hypotheses about stock and fishery dynamics to be explored. The intention is to illustrate the ways in which such models can be used and the types of advice that they can provide

A simulation of the Atlantic meridional circulation during Heinrich event 4 using reconstructed sea surface temperatures and salinities
Provedor de dados: 5
Autores: Paillard, Didier; Cortijo, Elsa.
With a simplified two-dimensionnal Atlantic Ocean model, we investigate the response of the deep ocean circulation to reconstructed sea surface salinity and temperature used as surface boundary conditions at two time slices: just before and during Heinrich event 4. In contrast to previous studies, we do not make any assumption about freshwater input. Our model results suggest that the recorded estimations of surface hydrological changes during an Heinrich event are able to induce a drastic slowdown, or even a collapse, of the overall Atlantic thermohaline circulation. This is, to some extent, consistent with records of the deep sea ventilation at these times.

A simulation of the effects of air-sea transfer variability on the structure of marine upper layers
Provedor de dados: 5
Autores: Klein, Patrice.
A rather simple one-dimensional unsteady model similar to Mellor and Durbin (1975) is used to study the effects of the time variability of meteorological inputs on the evolution of the thermal stratification of marine upper layers. The physical implications of such a model are discussed, particularly with respect to the results obtained in a number of typical situations. The thermal structure of the marine upper layers in the Gulf of Lion during the COFRASOY II expedition was also simulated. Although the model is not able to reproduce all details of the marine environment, the mixed-layer deepening and sea surface temperature are predicted rather well from the known meteorological parameters. It appears in conclusion that the most important...

A simulation-based approach to assess sensitivity and robustness of fisheries management indicators for the pelagic fishery in the Bay of Biscay
Provedor de dados: 5
Autores: Lehuta, Sigrid; Mahevas, Stephanie; Le Floc'H, Pascal; Petitgas, Pierre.
Indicators are widely promoted as means to monitor ecosystem status or to evaluate fisheries management performance. "Which indicators are most relevant as decision-support tools in fisheries management?" still remains a topical question. Indicators should be metrics related to fish populations and fleets and should be sensitive to management strategies. However, given the complexity of the processes involved, it is often difficult to unequivocally interpret variations in metrics. A simulation approach was used to study metric properties and to identify robust and relevant fishery indicators. By applying sensitivity analysis methods, simulation designs were built that cross a variety of management scenarios and uncertainty hypotheses. Bio-economic outputs...

A single bio-energetics growth and reproduction model for the oyster Crassostrea gigas in six Atlantic ecosystems
Provedor de dados: 5
Autores: Alunno-bruscia, Marianne; Bourles, Yves; Maurer, Daniele; Robert, Stephane; Mazurie, Joseph; Gangnery, Aline; Goulletquer, Philippe; Pouvreau, Stephane.
Many studies based on bioenergetics growth models have investigated the effects of environmental factors on oyster (Crassostrea gigas) growth and physiology. However, most of these models are site-specific and cannot be applied to other culture sites without the re-estimation of parameters or re-formulation of some processes. We aimed to develop a generic growth model suitable for application in contrasting environments, with a constant set of parameters. We tested the oyster-DEB model (Bourlès et al. 2009) for the stimulation of C. gigas growth in different cohorts (spats and adults) at major shellfish culture sites in France, in several years: Arcachon (1993–1994); Marennes-Oléron (2007); Quiberon (1999, 2000, 2001); Rade de Brest (2008); Baie du...

Oyster diseases caused by pathogenic vibrios pose a major challenge to the sustainability of oyster farming. In France since 2012 a disease affecting specifically adult oysters has been associated with the presence of Vibrio aestuarianus. Here, by combining genome comparison, phylogenetic analyses and high throughput infections of strains isolated before or during the recent outbreaks, we show that virulent strains cluster into two V. aestuarianus lineages independently of the sampling dates. The bacterial lethal dose was not different between strains isolated before or after 2012. Hence the emergence of a new highly virulent clonal strain is unlikely. Each lineage comprises nearly identical strains, the majority of them being virulent, suggesting that...

A Snapshot of the Population Structure of Branchiostoma lanceolatum in the Racou Beach, France, during Its Spawning Season
Provedor de dados: 5
Autores: Desdevises, Yves; Maillet, Vincent; Fuentes, Michael; Escriva, Hector.
A methodology for inducing spawning in captivity of the lancelet Branchiostoma lanceolatum has been developed recently with animals collected at the Racou beach, in the southern coast of France. An increasing amount of laboratories around the world are now working on the evolution of developmental mechanisms (Evo-Devo) using amphioxus collected in this site. Thus, today, the development of new aquaculture techniques for keeping amphioxus in captivity is needed and the study of the natural conditions at which amphioxus is exposed in the Racou beach during their spawning season becomes necessary. We have investigated the amphioxus distribution, size frequency, and population structure in the Racou beach during its natural spawning season using multivariate...

A soft technology to improve survival and reproductive performance of Litopenaeus stylirostris by counterbalancing physiological disturbances associated with handling stress
Provedor de dados: 5
Autores: Wabete, Nelly; Chim, Liet; Pham, Dominique; Lemaire, Pierrette; Massabuau, J.
The consequences of handling stress (fishing, transfer, eyestalk ablation) on shrimp broodstock are poorly documented. The weakness of farmed shrimp, Litopenaeus stylirostris, during winter is a major problem in New Caledonia, because of seasonal climate (tropical-sub-temperate). The transfer of broodstock in winter from earthen outdoor ponds to indoor maturation tanks in the hatchery (T=20 degrees C, Salinity=35 parts per thousand, fed shrimp) usually leads, after 48 h, to high mortality (up to 70%). Eyestalk ablation to induce ovarian maturation in females leads to further mortality.   Starting from a background analysis of physiological disturbances (initial osmoregulatory imbalance) associated with handling stress (Wabete, N., Chim, L., Lernaire, P.,...

The Lagrangian Transport Experiment (LATEX) was developed to study the influence of coupled physical and biogeochemical dynamics at the meso- and submesoscales on the transfers of matter and heat between the coastal zone and the open ocean. One of the goals of the Latex10 field experiment, conducted during September 2010 in the Gulf of Lion (northwest Mediterranean), was to mark a dynamical mesoscale feature by releasing a passive tracer [sulfur hexafluoride (SF6)] together with an array of Lagrangian buoys. The goal was to release the tracer in an initial patch as homogeneous as possible in the horizontal, and to study its turbulent mixing and dispersion while minimizing the contribution due to advection. For that, it was necessary to continuously adjust...

A Southern Ocean trigger for Northwest Pacific ventilation during the Holocene?
Provedor de dados: 5
Autores: Rella, S. F.; Uchida, M.
Holocene ocean circulation is poorly understood due to sparsity of dateable marine archives with submillennial-scale resolution. Here we present a record of mid-depth water radiocarbon contents in the Northwest (NW) Pacific Ocean over the last 12.000 years, which shows remarkable millennial-scale variations relative to changes in atmospheric radiocarbon inventory. Apparent decoupling of these variations from regional ventilation and mixing processes leads us to the suggestion that the mid-depth NW Pacific may have responded to changes in Southern Ocean overturning forced by latitudinal displacements of the southern westerly winds. By inference, a tendency of in-phase related North Atlantic and Southern Ocean overturning would argue against the development...

A spatial decision support system for enhancing resilience to floods: bridging resilience modelling and geovisualization techniques
Provedor de dados: 5
Autores: Heinzlef, Charlotte; Becue, Vincent; Serre, Damien.
In the context of climate change and increasing urbanization, floods are considerably affecting urban areas. The concept of urban resilience may be an interesting means of responding to urban flood issues. The objective of this research is to propose a spatial decision support tool based on geovisualization techniques and a resilience assessment method. The goal is to localize the level of resilience modelled in different territories. The methodology proposed consists of integrating three resilience indicators applied to a case study in Avignon (Provence-Alpes-Cote d'Azur region, France) and the use of geovisualization techniques: using GIS for data processing and analysis, visualization, mapping, and model processing. The methodology integrates...

A spatially explicit ecosystem model of seston depletion in dense mussel culture

Autores: Grant, J; Bacher, Cedric; Cranford, P; Guyondet, T; Carreau, M.
A fully-coupled biological-physical-chemical model of a coastal ecosystem was constructed to examine the impact of suspended mussel culture on phytoplankton biomass in Tracadie Bay, Prince Edward Island, Canada. Due to the extent of mussel culture there, we hypothesised that shellfish filtration would control the concentration and distribution of phytoplankton and other suspended particles in the bay. Circulation was delineated with a tidally-driven 2D numerical model and used to drive an ecosystem model with a focus on pelagic components including phytoplankton production, nutrients, detritus, and mussels. The benthos were treated as a sink. Nutrients and seston were forced by tidal exchange and river input, with phytoplankton additionally forced by...

A spatiotemporal study of bacterial community profiles associated with Atlantic bluefin tuna larvae, Thunnus thynnus L., in three Mediterranean hatcheries
Provedor de dados: 5
Autores: Gatesoupe, Joel; Coves, Denis; Ortega, Aurelio; Papandroulakis, Nikos; Vadstein, Olav; De La Gandara, Fernando.
During the first 2 years of larval rearing trials with Atlantic bluefin tuna, survival was a challenging issue. As bacterial colonization of the gut has been shown to play a key role for other species, we studied the profiles of the microbiota associated with individual larvae at different stages in three distant hatcheries. The Bacterial Community Profile (BCP) was quantified based on PCR-DGGE analyses of partial amplicons from 16S rDNA. Considerable individual variability in BCP was observed before onset of feeding, and the BCP did not show regular fluctuation during ontogenesis. Microalgae were added to the rearing tanks in two of the three hatcheries, but it was not possible to distinguish the effect of location from the effect of algal addition on...

A state-space model to derive bluefin tuna movement and habitat from archival tags
Provedor de dados: 5
Autores: Royer, Francois; Fromentin, Jean-marc; Gaspar, P.
Archival tagging provides a unique way to study the spatial dynamics and habitat of pelagic fish. This technique generates lagrangian data of a particular type in marine ecology: although highly informative about processes at different scales (e.g. horizontal movements versus diving behaviour), such data are impaired by location errors and the lack of combination with actual environmental variability. The present paper introduces a framework for modelling bluefin tuna movement in relation to its habitat, using records of light, depth and temperature from archival tags. Based on data assimilation concepts and methods, we show how an explicit formulation of the observation process and the statistics of external variables (e.g. ambient temperature) can...

A Statistical Algorithm for Estimating Chlorophyll Concentration in the New Caledonian Lagoon
Provedor de dados: 5
Autores: Wattelez, Guillaume; Dupouy, Cecile; Mangeas, Morgan; Lefevre, Jerome; Touraivane,; Frouin, Robert.
Spatial and temporal dynamics of phytoplankton biomass and water turbidity can provide crucial information about the function, health and vulnerability of lagoon ecosystems (coral reefs, sea grasses, etc.). A statistical algorithm is proposed to estimate chlorophyll-a concentration ([chl-a]) in optically complex waters of the New Caledonian lagoon from MODIS-derived remote-sensing reflectance (R-rs). The algorithm is developed via supervised learning on match-ups gathered from 2002 to 2010. The best performance is obtained by combining two models, selected according to the ratio of R-rs in spectral bands centered on 488 and 555 nm: a log-linear model for low [chl-a] (AFLC) and a support vector machine (SVM) model or a classic model (OC3) for high [chl-a]....

The Sea of Marmara is traversed by the North Anatolian Fault system and also presents abundant emission sites of methane gas into the water column. In order to assess the spatial relationship between gas emissions and active faults, the distribution of distances between gas emission sites and the nearest fault is calculated and compared with the distribution of distances between a uniform random distribution of points (Poisson process representing the null hypothesis of an absence of relationship between gas emissions and faults) and the nearest fault. Interestingly, the distance distribution for the Poisson process is nearly exponential, indicating that the fault map does not have a characteristic scale other than that representing the intensity of the...

Autores: Jones, Steve D.; Le Quere, Corinne; Roedenbeck, Christian; Manning, Andrew C.; Olsen, Are.
We have developed a statistical gap-filling method adapted to the specific coverage and properties of observed fugacity of surface ocean CO2 (fCO2). We have used this method to interpolate the Surface Ocean CO2 Atlas (SOCAT) v2 database on a 2.5°×2.5° global grid (south of 70°N) for 1985–2011 at monthly resolution. The method combines a spatial interpolation based on a “radius of influence” to determine nearby similar fCO2 values with temporal harmonic and cubic spline curve-fitting, and also fits long-term trends and seasonal cycles. Interannual variability is established using deviations of observations from the fitted trends and seasonal cycles. An uncertainty is computed for all interpolated values based on the spatial and temporal range of the...

A steady-state model of PCB accumulation in dab food web

Autores: Loizeau, Veronique; Menesguen, Alain.
A five-compartment steady-state food web model is proposed for the benthic food web leading to the dab. Three exposure pathways are considered in the description of accumulation by benthic animals: ingestion of particulate contaminants associated with either sediment or phytoplankton, and respiratory uptake of free dissolved contaminant in overlaying water. Application of the model to a simple food web in the Bay of Seine (Eastern Channel) indicates that : a) feeding is the principal route of contamination, especially for PCB which have more than four chlorine atoms in the molecule ; b) excretion and growth rates, phytoplankton lipid fraction and organic carbon content of sediment are the parameters which mostly determine the chemical bioaccumulation in...

A step toward the definition of ecological indicators of the impact of fishing on the fish assemblage of the Abore reef reserve (New Caledonia)
Provedor de dados: 5
Autores: Amand, Marion; Pelletier, Dominique; Ferrari, Jocelyne; Kulbicki, Michel.
Marine Protected Areas (MPA) are often contemplated as a tool for the sustainable management of exploited resources and ecosystem conservation. This paper proposes an approach to establish a statistical diagnostic of the effects of MPAs on fish assemblages, and define corresponding ecological indicators. This requires choosing relevant variables (abundance, diversity, demographic parameters..) and appropriate statistical methods. The study was based on data from the Abore reef Reserve in New Caledonia. Two sets of methods: 1-inferential linear models (ANOVA, GLM): 2- Partial Least Squares (PLS) methods of regression, were used to test the effects of this MPA. PLS enabled us to test simultaneously within a model, density, species richness, biomass and mean...

This paper describes a detailed implementation of the Synthetic Eddy Method (SEM) initially presented in Jarrin et al. (2006) applied to the Lagrangian Vortex simulation. While the treatment of turbulent diffusion is already extensively covered in scientific literature, this is one of the first attempts to represent ambient turbulence in a fully Lagrangian framework. This implementation is well suited to the integration of PSE (Particle Strength Exchange) or DVM (Diffusion Velocity Method), often used to account for molecular and turbulent diffusion in Lagrangian simulations. The adaptation and implementation of the SEM into a Lagrangian method using the PSE diffusion model is presented, and the turbulent velocity fields produced by this method are then...

A stochastic viability approach to ecosystem-based fisheries management
Provedor de dados: 5
Autores: Doyen, Luc; Thebaud, Olivier; Bene, Christopher; Martinet, V.; Gourguet, S.; Bertignac, Michel; Fifas, Spyros; Blanchard, Fabian.
Academia and management agencies show a growing interest for ecosystem-based fishery management (EBFM). However, the way to operationalize this approach remains challenging. The present paper illustrates how the concepts of stochastic co-viability, which accounts for dynamic complexities, uncertainties, risk and sustainability constraints, can be useful for the implementation of EBFM. In the present case, this concept is used to identify fishing strategies that satisfy both ecological conservation and economic sustainability in a multi-species, multi-fleet context. Economic Viability Analysis (EVA) and the broader Co-Viability Analysis (CVA), are proposed to expand the usual Population Viability Analysis (PVA) and precautionary approach. An illustration is...

A strong link between marine microbial community composition and function challenges the idea of functional redundancy
Provedor de dados: 5
Autores: Galand, Pierre E.; Pereira, Olivier; Hochart, Corentin; Auguet, Jean-christophe; Debroas, Didier.
Marine microbes have tremendous diversity, but a fundamental question remains unanswered: why are there so many microbial species in the sea? The idea of functional redundancy for microbial communities has long been assumed, so that the high level of richness is often explained by the presence of different taxa that are able to conduct the exact same set of metabolic processes and that can readily replace each other. Here, we refute the hypothesis of functional redundancy for marine microbial communities by showing that a shift in the community composition altered the overall functional attributes of communities across different temporal and spatial scales. Our metagenomic monitoring of a coastal northwestern Mediterranean site also revealed that diverse...

A study of autophagy in hemocytes of the Pacific oyster,   Crassostrea gigas
Provedor de dados: 5
Autores: Picot, Sandy; Morga, Benjamin; Faury, Nicole; Chollet, Bruno; Dégremont, Lionel; Travers, Marie-agnes; Renault, Tristan; Arzul, Isabelle.
Macroautophagy is a mechanism that is involved in various cellular processes, including cellular homeostasis and innate immunity. This pathway has been described in organisms ranging in complexity from yeasts to mammals, and recent results indicate that it occurs in the mantle of the Pacific oyster, Crassostrea gigas. However, the autophagy pathway has never been explored in the hemocytes of C. gigas, which are the main effectors of its immune system and thus play a key role in the defence of the Pacific oyster against pathogens. To investigate autophagy in oyster hemocytes, tools currently used to monitor this mechanism in mammals, including flow cytometry, fluorescent microscopy and transmission electron microscopy, were adapted and applied to the...

A study of geochemistry and hydrodynamics in Hutt Lagoon (Western Australia)
Provedor de dados: 5
Autores: Arakel, A V.
Hutt Lagoon, in the Perth Basin, Western Australia is a shallow (&lt; 11 m) evaporitic basin, developed as a result of ponding in a Pleistocene calcreted dune terrain. Holocene sequence in the lagoon reflects a history of evaporite sedimentation through successive stages ranging from open marine to pond and playa environments. The contemporary lagoon is a playa surface in which sedimentation is related to distribution and interaction of hydrologic units (groundwaters, seawaters and lagoonal brines). Precipitation is restricted to ephemeral halite in ponded waters, and diagentic emplacement of CaCO sub(3) and CaSO sub(4) minerals in lagoonal sediments. Playa surfaces, predominantly below sea-level, fundamentally control the lagoonal circulation system;...

A study of the dynamics of the British Ice Sheet during Marine Isotope Stages 2 and 3, focusing on Heinrich Events 2 and 4 and their relationship to the North Atlantic glaciological and climatological conditions
Provedor de dados: 5
Autores: Leigh, Sasha Naomi Bharier.
A high-resolution investigation into the stratigraphy of core MD95-2006 from the Barra fan, NW Scottish continental slope has been carried out. The study focuses on key palaeoceanographic proxies (percentage Neogloboquadrina pachyderma (s), planktonic foraminiferal stable isotopes, planktonic foraminiferal and ice-rafted debris concentrations) throughout the interval between and including Heinrich Event 4 and Heinrich Event 2. A newly constructed age model produced through ties to the GRIP Greenland ice core record places this interval at approximately 20-48 ka BP. The interval covers the end of Marine Isotope Stage 3 and the start of Marine Isotope Stage 2, dating the MIS3/2 transition at 25.34-26.57 ka BP. Results reveal novel information on the dynamics...

A study of the non-linear behaviour of adhesively-bonded composite assemblies
Provedor de dados: 5
Autores: Cognard, Jean Yves; Davies, Peter; Sohier, S; Creac' Hcadec, R.
The objective of this study is to define a reliable tool for dimensioning of adhesively bonded assemblies, particularly for marine and underwater applications. This paper presents experimental and numerical results, which describe the non-linear behaviour of an adhesive in a bonded assembly for various loadings. A modified Arcan fixture, well-suited for the study of the behaviour of bonded metal-metal assemblies, was developed in order to focus on the analysis of the behaviour of the adhesive in thin films. The edge effects are minimised by using an appropriate design of the substrates so that experimental results give reliable data. To analyze the kinematics of the deformation of the adhesive joint non-contact extensometry techniques were employed. Thus,...

A study of the phase instability of quasi-geostrophic Rossby waves on the infinite beta-plane to zonal flow perturbations
Provedor de dados: 5
Autores: Marie, Louis.
The problem of the linear instability of quasi-geostrophic Rossby waves to zonal flow perturbations is investigated on an infinite beta-plane using a phase dynamics formalism. Equations governing the coupled evolutions of a zonal velocity perturbation and phase and amplitude perturbations of a finite-amplitude wave are obtained. The analysis is valid in the limit of infinitesimal, zonally invariant perturbation components, varying slowly in the meridional direction and with respect to time. In the case of a slow sinusoidal meridional variation of the perturbation components, analytical expressions for the perturbation growth rates are obtained, which are checked against numerical codes based on standard Floquet theory.

A study of the slope probability density function of the ocean waves from radar observations
Provedor de dados: 5
Autores: Hauser, D.; Caudal, G.; Guimbard, Sebastien; Mouche, Alexis.
Radar observations of the sea surface at C-Band and small incidence angles are used to investigate some properties of the surface slope probability density function (pdf). The method is based on the analysis of the variation of the radar cross-section with incidence angle, assuming a backscattering process following the Geometrical Optics theory. First, we assess the limit of this model in our experimental configuration by using simulations of radar cross-sections with a more accurate backscattering model, namely the Physical Optics model. We show that roughness properties with scales larger than 12 cm can be analyzed in our configuration (C-Band, incidence 7 to 16 degrees). The radar data are then analyzed in terms of filtered mean square slope under the...

Autores: Sarma, Vvss; Narvekar, Pv.
Extensive data have been collected on the carbon dioxide system during the post monsoon season in the eastern Bay of Bengal and the Andaman Sea of the northeastern Indian Ocean. The vertical distribution of temperature and salinity in the eastern Bay of Bengal were similar to that in the Andaman Sea down to 700-800 m. Below 1200 m depth the salinity remained constant at 34.90 in the Andaman Sea whereas it decreased to 34.80 in the eastern Bay of Bengal. On the other hand, deep waters (&gt; 1200 m) of the Andaman Sea were warmer than those of the Bay of Bengal by approximately 2 degreesC. Dissolved oxygen concentrations in the subsurface waters were higher in the Andaman Sea than in the central Bay of Bengal and Arabian Sea due to lower rates of...

Autores: Boudiere, Edwige; Maisondieu, Christophe; Ardhuin, Fabrice; Accensi, Mickael; Pineau-guillou, Lucia; Lepesqueur, Jeremy.
Resource assessment as well as characterisation of site climatologies for the design of Marine Energy Converters requires data bases allowing an accurate description of the environmental forcing, especially waves and sea-states, on a high resolution grid. As a support to its research activities related to the development of marine renewable energies, Ifremer is building a specific hindcast data set for the assessment of sea-states climatologies. The main features of this database, built running an up-to-date configuration of the WaveWatch III® wave model on an unstructured grid extending from the South of the North Sea to the Bay of Biscay are presented here.

The Middle America Trench off Guatemala was transected by 24-channel seismic-reflection surveys, seismic-refraction surveys, and drilling with the Glomar Challanger . The drilling was doneat three sites on the oceanic Cocos plate and four sites on the Caribbean plate. These plates converge at about 10 cm/yr as indicated by global plate reconstruction. On the oceanic Cocos plate a basal chalk sequence of lower and middle Miocene age is overlain by a thin interval of abyssal clay. In contrast is the Cretaceous to lower Miocene claystone sequence recovered only at a site 3 km landward of the trench axis where drilling penetrated the hemipelagic slope deposits. A large amount of sediment along with ocean crust has been subducted during the present (Miocene to...

A Summary of Results From the IPOD Transects Across the Japan, Mariana, and Middle-America Convergent Margins
Provedor de dados: 5
Autores: Von Huene, R; Uyeda, S.
Investigations of convergent margins along the IPOD transects support the concept of ocean floor spreading in back-arc basins and the concept of tectonically accreted sediment at the front of convergent margins. However, not all convergent margins have large accreted complexes, and other less frequently used concepts are required in the interpretations of these convergent margins. If the present rates of plate convergence are accepted, then much sediment that entered the trenches studied is presumably subducted rather than accreted. In some instances, the continental framework is truncated and somehow removed by tectonic erosion. Some convergent margins have subsided significantly during subduction. The crust above the Benioff zone appears to have been...

Autores: Veras Guimaraes, Pedro; Ardhuin, Fabrice; Sutherland, Peter; Accensi, Mickael; Hamon, Michel; Perignon, Yves; Thomson, Jim; Benetazzo, Alvise; Ferrant, Pierre.
Global navigation satellite systems (GNSSs) and modern motion-sensor packages allow the measurement of ocean surface waves with low-cost drifters. Drifting along or across current gradients provides unique measurements of wave–current interactions. In this study, we investigate the response of several combinations of GNSS receiver, motion-sensor package and hull design in order to define a prototype “surface kinematics buoy” (SKIB) that is particularly optimized for measuring wave–current interactions, including relatively short wave components that are important for air–sea interactions and remote-sensing applications.

The Surface Ocean CO2 NETwork (SOCONET) and atmospheric Marine Boundary Layer (MBL) CO2 measurements from ships and buoys focus on the operational aspects of measurements of CO2 in both the ocean surface and atmospheric MBLs. The goal is to provide accurate pCO(2) data to within 2 micro atmosphere (mu atm) for surface ocean and 0.2 parts per million (ppm) for MBL measurements following rigorous best practices, calibration and intercomparison procedures. Platforms and data will be tracked in near real-time and final quality-controlled data will be provided to the community within a year. The network, involving partners worldwide, will aid in production of important products such as maps of monthly resolved surface ocean CO2 and air-sea CO2 flux...

Autores: Colas, Florent; Crassous, Marie-pierre; Laurent, Sebastien; Litaker, Richard W.; Rinnert, Emmanuel; Le Gall, Erwan; Lunven, Michel; Delauney, Laurent; Compère, Chantal.
Over the past decade Surface Plasmon Resonance (SPR) techniques have been applied to the measurement of numerous analytes. In this article, an SPR biosensor system deployed from an oceanographic vessel was used to measure dissolved domoic acid (DA), a common and harmful phycotoxin produced by certain microalgae species belonging to the genus Pseudo-nitzschia. During the biosensor deployment, concentrations of Pseudo-nitzschia cells were very low over the study area and measured DA concentrations were below detection. However, the in situ operational detection limit of the system was established using calibrated seawater solutions spiked with DA. The system could detect the toxin at concentrations as low as 0.1 ng mL−1 and presented a linear dynamic range...

Autores: Maes, C.; Grima, N.; Blanke, Bruno; Martinez, E.; Paviet-salomon, T.; Huck, Thierry.
We study the dispersion and convergence of marine floating material by surface currents from a model reanalysis that represents explicitly mesoscale eddy variability. Lagrangian experiments about the long-term evolution (29 years) of an initially homogeneous concentration of particles are performed at global scale with horizontal current at ¼° resolution and refreshed daily over the 1985-2013 period. Results confirm and document the five known sites of surface convergence at the scale of individual oceanic basins, but also reveal a convergent pathway connecting the South Indian subtropical region with the convergence zone of the South Pacific through the Great Australian Bight, the Tasman Sea and the southwest Pacific Ocean. This “super-convergent” pathway...

A survey of the age structure of beach populations of Nephtys species in the British Isles. The basis of population fluctuations. An earlier investigation on Nephtys populations in an estuarine beach has been extended to include other beaches. It has been become apparent that periodic reproductive failure is a common phenomenon, and this explains why many populations are dominated by large, apparently old individuals which have numerous growth lines in the jaws. Reproductive failures are often the result of a failure to spawn, but may also be due to lack of recruitment.

Over the last decade, innate immune priming has been evidenced in many invertebrate phyla. If mechanistic models have been proposed, molecular studies aiming to substantiate these models have remained scarce. We reveal here the transcriptional signature associated with immune priming in the oyster Crassostrea gigas. Oysters were fully protected against Ostreid herpesvirus 1 (OsHV-1), a major oyster pathogen, after priming with poly(I·C), which mimics viral double-stranded RNA. Global analysis through RNA sequencing of oyster and viral genes after immune priming and viral infection revealed that poly(I·C) induces a strong antiviral response that impairs OsHV-1 replication. Protection is based on a sustained upregulation of immune genes, notably genes...

A Synthesis of Deglacial Deep-Sea Radiocarbon Records and Their (In)Consistency With Modern Ocean Ventilation
Provedor de dados: 5
Autores: Zhao, Ning; Marchal, Olivier; Keigwin, Lloyd; Amrhein, Daniel; Gebbie, Geoffrey.
We present a synthesis of 1,361 deep-sea radiocarbon data spanning the past 40kyr and computed (for C-14-dated records) from the same calibration to atmospheric C-14. The most notable feature in our compilation is a long-term Delta C-14 decline in deep oceanic basins over the past 25kyr. The Delta C-14 decline mirrors the drop in reconstructed atmospheric Delta C-14, suggesting that it may reflect a decrease in global C-14 inventory rather than a redistribution of C-14 among different reservoirs. Motivated by this observation, we explore the extent to which the deep water C-14 data jointly require changes in basin-scale ventilation during the last deglaciation, based on the fit of a 16-box model of modern ocean ventilation to the deep water Delta C-14...

The isotopic composition of carbon, delta C-13, in seawater is used in reconstructions of ocean circulation, marine productivity, air-sea gas exchange, and biosphere carbon storage. Here, a synthesis of delta C-13 measurements taken from foraminifera in marine sediment cores over the last 150 000 years is presented. The dataset comprises previously published and unpublished data from benthic and planktonic records throughout the global ocean. Data are placed on a common delta O-18 age scale suitable for examining orbital timescale variability but not millennial events, which are removed by a 10 ka filter. Error estimates account for the resolution and scatter of the original data, and uncertainty in the relationship between delta C-13 of calcite and of...

The Demerara Plateau, off the French Guiana and Surinam margin, corresponds to a prominent sub-horizontal marginal plateau. The interpretation of a large set of seismic data acquired along the Demerara Plateau and integration with previous seismic stratigraphy and drill studies enables a better understanding of the sedimentary evolution of the outer Demerara marginal plateau. Since the end of the transform activity (late Albian), three sedimentary evolutionary stages have been identified. 1) The Pre-contourite Stage (late Albian to early Miocene) is strongly controlled by the structure of the margin that influences the distribution pattern of post-transform deposits through differential thermal subsidence between transform and divergent segments. 2) The...

The ambient turbulence intensity is a key factor in the study of marine current turbines. Indeed recent studies have shown that ambient turbulence intensity highly modifies the behavior of horizontal axis marine current turbines. Consequently numerical simulations have to represent the ambient turbulence or at least its effects on the performance and wake of the turbines. This paper presents the latest numerical developments carried out at LOMC in collaboration with IFREMER in order to take into account the effects of ambient turbulence.

Cooperation between the social and natural sciences has become essential in order to encompass all the dimensions of coastal zone management. Socio-economic approaches are increasingly recommended to complement integrated assessment in support of these initiatives. A systematic review of the academic literature was carried out in order to analyze the main types of socio-economic assessments used to inform the coastal zone management process as well as their effectiveness. A corpus of 1682 articles published between 1992 and 2011 was identified by means of the representative coverage approach, from which 170 were selected by applying inclusion/exclusion criteria and then classified using a content analysis methodology.

Although most chitons (Mollusca: Polyplacophora) are shallow-water molluscs, diverse species also occur in deep-sea habitats. We investigated the feeding strategies of two species, Leptochiton boucheti and Nierstraszella lineata, recovered on sunken wood sampled in the western Pacific, close to the Vanuatu Islands. The two species display distinctly different associations with bacterial partners. Leptochiton boucheti harbours Mollicutes in regions of its gut epithelium and has no abundant bacterium associated with its gill. Nierstraszella lineata displays no dense gut-associated bacteria, but harbours bacterial filaments attached to its gill epithelium, related to the Deltaproteobacteria symbionts found in gills of the wood-eating limpet Pectinodonta sp....

Human noroviruses (NoV) cause epidemics of acute gastroenteritis (AGE) worldwide and can be transmitted through consumption of contaminated foods. Fresh products such as shellfish can be contaminated by human sewage during production, which results in the presence of multiple virus strains, at very low concentrations. Here, we tested a targeted metagenomics approach by deep-sequencing PCR amplicons of the capsid (VP1) and polymerase (RdRp) viral genes, on a set of artificial samples and on shellfish samples associated to AGE outbreaks, to evaluate its advantages and limitations in the identification of strains from the NoV genogroup (G) II. Using artificial samples, the method allowed the sequencing of most strains, but not all, and displayed variability...

About 30 benthic Prorocentrum species have been described, some of which producing okadaic acid and derivatives involved in diarrhetic shellfish poisoning. The western Caribbean has been extensively studied for benthic dinoflagellates associated with ciguatera, and fifteen Prorocentrum species were described from mangroves and coral reefs of Belize. In contrast, no study reported the diversity of this genus in the Eastern Caribbean, especially in the Lesser Antilles. This study adds to the biodiversity knowledge in Martinique Island by investigating one site of the Caribbean coast from 2010 to 2017. Sediment samples were collected each year in March and studied taxonomically. Identification was realized morphologically by scanning electron microscopy,...

A tectonic test of instantaneous kinematics of the Easter Microplate
Provedor de dados: 5
Autores: Zukin, J-h; Francheteau, J.
Detailed studies of the Easter microplate, and other contemporary microplates located along the world's mid-oceanic ridge system, are considered of primary importance to our understanding of the kinematic evolution of the major oceanic plates. The focus of the Rapanui expedition, part of the "Tour du monde" of the French research vessel Jean Charcot , was to collect detailed structural and geophysical data along the northern and southern Easter microplate boundaries in order to test, in a rigorous manner, the most recent tectonic and kinematic models for the microplate. In developing detailed bathymetric, morphotectonic and magnetic maps of these boundaries, we have found that our new plate boundaries differ considerably from those of Hey et al. (1985).

A Tentative Age-based Assessment of the Northern Stock of European Hake
Provedor de dados: 5
Autores: Mesnil, Benoit; Guichet, Roger.
Due to difficulties in routinely ageing European hake, assessments of the stock have hitherto been carried out using length-based methods, and were thus restricted to pseudo-cohort analyses and long-term equilibrium projections under steady state assomptions. However, given the availability of numerical length-to-age conversion methods, it seems feasible to consider age-based assessments using the methodology of regular ICES working groups. In this paper, attempts are made to derive a time series of catches at age from the length compositions of international catches assembled by the ICES Hake Working Group for the period 1978-1990. The age-length key which is reconstructed in each year is also applied to the length composition of catches by selected...

A test of community assembly rules using foliar endophytes from a tropical forest canopy
Provedor de dados: 5
Autores: Donald, Julian; Roy, Mélanie; Suescun, Uxue; Iribar, Amaia; Manzi, Sophie; Péllissier, Léonie; Gaucher, Philippe; Chave, Jérôme.
1.Community assembly theory assumes that ecological communities are spatially delimited into patches. Within these patches, coexistence results from environmental filtering, competition, and immigration. Truly delineated communities exist in laboratory studies of microbial cultures in Petri dishes, yet empirical tests conducted in continuous environments often use patches defined by convention as opposed to realised boundaries. 2.Here we perform a test of ecological community assembly rules using foliar endophyte communities from a tropical rainforest, where leaves are considered as patches for both fungal and bacterial communities. We determined the diversity of fungal and bacterial endophytes using environmental DNA sequencing of 365 top‐canopy leaves,...

Coelacanth fishes of the genus Latimeria are the only surviving representatives of a basal lineage of vertebrates that originated more than 400 million years ago. Yet, much remains to be unveiled about the diversity and evolutionary history of these ‘living fossils’ using new molecular data, including the possibility of ‘cryptic’ species or unknown lineages. Here, we report the discovery of a new specimen in eastern Indonesia allegedly belonging to the species L. menadoensis. Although this specimen was found about 750 km from the known geographical distribution of the species, we found that the molecular divergence between this specimen and others of L. menadoensis was great: 1.8% compared to 0.04% among individuals of L. chalumnae, the other living...

A three-dimensional view on biodiversity changes: spatial, temporal, and functional perspectives on fish communities in the Baltic Sea

Autores: Frelat, Romain; Orio, Alessandro; Casini, Michele; Lehmann, Andreas; Merigot, Bastien; Otto, Saskia A.; Sguotti, Camilla; Moellmann, Christian.
Fisheries and marine ecosystem-based management requires a holistic understanding of the dynamics of fish communities and their responses to changes in environmental conditions. Environmental conditions can simultaneously shape the spatial distribution and the temporal dynamics of a population, which together can trigger changes in the functional structure of communities. Here, we developed a comprehensive framework based on complementary multivariate statistical methodologies to simultaneously investigate the effects of environmental conditions on the spatial, temporal and functional dynamics of species assemblages. The framework is tested using survey data collected during more than 4000 fisheries hauls over the Baltic Sea between 2001 and 2016. The...

A Three‐way Balance in The Beaufort Gyre: The Ice‐Ocean Governor, Wind Stress, and Eddy Diffusivity
Provedor de dados: 5
Autores: Doddridge, Edward W.; Meneghello, Gianluca; Marshall, John; Scott, Jon; Lique, Camille.
The Beaufort Gyre (BG) is a large anticyclonic circulation in the Arctic Ocean. Its strength is directly related to the halocline depth, and therefore also to the storage of freshwater. It has recently been proposed that the equilibrium state of the BG is set by the Ice‐Ocean Governor, a negative feedback between surface currents and ice‐ocean stress, rather than a balance between lateral mesoscale eddy fluxes and surface Ekman pumping. However, mesoscale eddies are present in the Arctic Ocean; it is therefore important to extend the Ice‐Ocean Governor theory to include lateral fluxes due to mesoscale eddies. Here, a non‐linear ordinary differential equation is derived that represents the effects of wind stress, the Ice‐Ocean Governor, and eddy fluxes....

A time-frequency application with the Stokes-Woodward technique
Provedor de dados: 5
Autores: Elfouhaily, Tanos; Guignard, S; Branger, H; Thompson, D; Chapron, Bertrand; Vandemark, D.
In a recent paper, we have generalized Woodward's theorem and applied it to the case of random signals jointly modulated in amplitude and frequency. This generalization yields a new spectral technique to estimate the amount of energy due to mode coupling without calling for higher order statistics. Two power spectra are detected; the first is related to the independent modes, and the second contains extra energy caused by mode coupling. This detection is now extended from frequency to time-frequency domain. A comparison between a wavelet transform and our time-frequency technique shows good agreement along with new insight into the time occurrence of the nonlinearities or mode coupling. An application to water surface waves is given in this letter as an...

A toolbox to evaluate data reliability for whole-ecosystem models: Application on the Bay of Biscay continental shelf food-web model
Provedor de dados: 5
Autores: Lassalle, Geraldine; Bourdaud, Pierre; Saint-beat, Blanche; Rochette, Sebastien; Niquil, Nathalie.
Ecosystem models are always simplifications of reality and as such their application for ecosystem-based management requires standard validation. Here, the “DataReli” toolbox is proposed to evaluate the quality of the data used during the construction of ecosystem models, their coherence across trophic levels, and whether data limitations prevent the model long-term applications. This toolbox is the combination of three operational and complementary analyses: (i) the pedigree index to determine to what extent a model was calibrated on data of local origin; (ii) the graphical analysis known as PREBAL to assess whether a model respects some basic ecological and fisheries principles; and (iii) a sensitivity analysis to evaluate the robustness of model...

A transcriptomic approach of salinity response in the euryhaline teleost, Dicentrarchus labrax
Provedor de dados: 5
Autores: Boutet, Isabelle; Ky, Chin Long; Bonhomme, Francois.
Euryhaline teleosts possess the capacity to osmoregulate under various environmental conditions (freshwater to hypersaline water). This physiological capacity is generally monitored using enzyme activity assays (Na+/K+-ATPase...), hormones quantification (prolactine, growth hormone) or their mRNAs expression. To date, few studies addressed the genetic correlates of adaptation to varying salinity at a molecular level in such fish. In the sea bass Dicentrarchus labrax, genetic differentiation was observed at specific allozyme loci between lagoon- and open-sea populations. In the present study, we investigated transcriptomic response of D. labrax to salt- and freshwater acclimation in two organs involved in osmoregulation, gill and intestine. By using...

A transposable element annotation pipeline and expression analysis reveal potentially active elements in the microalga Tisochrysis lutea
Provedor de dados: 5
Autores: Berthelier, Jeremy; Casse, Nathalie; Daccord, Nicolas; Jamilloux, Veronique; Saint-jean, Bruno; Carrier, Gregory.
Background Transposable elements (TEs) are mobile DNA sequences known as drivers of genome evolution. Their impacts have been widely studied in animals, plants and insects, but little is known about them in microalgae. In a previous study, we compared the genetic polymorphisms between strains of the haptophyte microalga Tisochrysis lutea and suggested the involvement of active autonomous TEs in their genome evolution. Results To identify potentially autonomous TEs, we designed a pipeline named PiRATE (Pipeline to Retrieve and Annotate Transposable Elements, download: https://doi.org/10.17882/51795), and conducted an accurate TE annotation on a new genome assembly of T. lutea. PiRATE is composed of detection, classification and annotation steps. Its...

A triage approach to improve the relevance of marine ecosystem services assessments
Provedor de dados: 5
Autores: Pendleton, Linwood; Mongruel, Remi; Beaumont, Nicola; Hooper, Tara; Charles, Mahe.
Ecosystem services assessments are increasingly being used to inform marine policy and planning. These assessments involve significant time, effort, and expertise. It is important at the outset to determine which of many ecosystem services should be quantified and which measures of ecological output, economic impact, or value should be assessed. Furthermore, the literature shows that in practice such assessments are unevenly applied and rarely used effectively in decision-making processes. We develop a structured decision-making approach, called a triage, to assess what types of ecosystem services should be assessed to improve the uptake and usefulness of such information in marine planning. Two case studies, in France and the United Kingdom, provide...

This work combines state-of-the-art methods (DNA metabarcoding) with classic approaches (visual stomach content characterization and stable isotope analyses of nitrogen (δ15N) and carbon (δ13C)) to investigate the trophic ecology of anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) at high taxonomic and spatial resolution in the Western Mediterranean Sea. Gut contents observed are in accordance with the dietary plasticity generally described for anchovy and sardine, suggesting a diet related to the opportunistic ingestion of available prey in a certain area and/or time. Genetic tools also showed modest inter-specific differences regarding ingested species. However, inter-specific and intra-specific differences in ingested prey frequencies...

A two-component parameterization of marine ice-nucleating particles based on seawater biology and sea spray aerosol measurements in the Mediterranean Sea
Provedor de dados: 5

Ice-nucleating particles (INPs) have a large impact on the climate-relevant properties of clouds over the oceans. Studies have shown that sea spray aerosols (SSAs), produced upon bursting of bubbles at the ocean surface, can be an important source of marine INPs, particularly during periods of enhanced biological productivity. Recent mesocosm experiments using natural seawater spiked with nutrients have revealed that marine INPs are derived from two separate classes of organic matter in SSAs. Despite this finding, existing parameterizations for marine INP abundance are based solely on single variables such as SSA organic carbon (OC) or SSA surface area, which may mask specific trends in the separate classes of INP. The goal of this paper is to improve the...

A two-dimensional analytical model of vertical water entry for asymmetric bodies with flow separation
Provedor de dados: 5
Autores: Hascoët, Romain; Jacques, Nicolas; Scolan, Yves-marie; Tassin, Alan.
The vertical water entry of asymmetric two-dimensional bodies with flow separation is considered. As long as there is no flow separation, linearised Wagner's theory combined with the modified Logvinovich model has been shown to provide computationally fast and reliable estimates of slamming loads during water entry. Tassin et al. [11] introduced the fictitious body continuation (FBC) concept as a way to extend the use of Wagner's model to separated flow configurations, but they only considered symmetric bodies. In the present study, we investigate the ability of the FBC concept to provide accurate estimates of slamming loads for asymmetric bodies. In this case, flow separation may not occur simultaneously on both sides of the body. During an intermediate...

A two-dimensional hydrodynamic model coupled to a particle tracking model is applied to study the dispersion processes and residence time in two Galician rias (A Coruna and Vigo, NW Spain) under summer conditions. In A Coruna a long residence time was found in the harbour area due to the existence of a dock, and a short one in the river area. On the contrary, in Vigo, the residence time is smaller in the harbour area, due to the Rande Strait, beyond which the river effect is negligible.

The past two million years of eastern African climate variability is currently poorly constrained, despite interest in understanding its assumed role in early human evolution1,2,3,4. Rare palaeoclimate records from northeastern Africa suggest progressively drier conditions2,5 or a stable hydroclimate6. By contrast, records from Lake Malawi in tropical southeastern Africa reveal a trend of a progressively wetter climate over the past 1.3 million years7,8. The climatic forcings that controlled these past hydrological changes are also a matter of debate. Some studies suggest a dominant local insolation forcing on hydrological changes9,10,11, whereas others infer a potential influence of sea surface temperature changes in the Indian Ocean8,12,13.

A two-stage biomass model to assess the English Channel cuttlefish (Sepia officinalis L.) stock
Provedor de dados: 5
Autores: Gras, Michael; Roel, Beatriz A.; Coppin, Franck; Foucher, Eric; Robin, Jean-paul.
The English Channel cuttlefish (Sepia officinalis) is the most abundant cephalopod resource in the Northeast Atlantic and one of the three most valuable resources for English Channel fishers. Depletion methods and age-structured models have been used to assess the stock, though they have shown limitations related to the model assumptions and data demand. A two-stage biomass model is, therefore, proposed here using, as input data, four abundance indices derived from survey and commercial trawl data collected by Ifremer and Cefas. The model suggests great interannual variability in abundance during the 17 years of the period considered and a decreasing trend in recent years. Model results suggest that recruitment strength is independent of spawning-stock...

A two-stage biomass random effects model for stock assessment without catches: What can be estimated using only biomass survey indices?
Provedor de dados: 5
Autores: Trenkel, Verena.
A simple two-stage biomass random effects population dynamics model is presented for carrying out fish stock assessments based on survey indices using no commercial catch information. Recruitment and biomass growth are modelled as random effects, reducing the number of model parameters while maintaining model flexibility. No assumptions regarding natural mortality rates are required. The performance of the method was evaluated using simulated data with emphasis on identifying parameter redundancy, which showed that the variance of the biomass growth random effect might only be estimable if large (&gt; 0.2). The full and two nested models were fitted to European anchovy (Engraulis encrasicolus) in the Bay of Biscay using two survey series. The best-fitting...

The Messinian Salinity Crisis is well known to have resulted from a significant drop of the Mediterranean sea level. Considering both onshore and offshore observations, the subsequent reflooding is generally thought to have been very sudden. We present here offshore seismic evidence from the Gulf of Lions and re-visited onshore data from Italy and Turkey that lead to a new concept of a two-step reflooding of the Mediterranean Basin after the Messinian Salinity Crisis. The refilling was first moderate and relatively slow accompanied by transgressive ravinement, and later on very rapid, preserving the subaerial Messinian Erosional Surface. The amplitude of these two successive rises of sea level has been estimated at =500 similar to m for the first rise and...

A unified deep-to-shallow water wave-breaking probability parameterization
Provedor de dados: 5
Autores: Filipot, Jean-francois; Ardhuin, Fabrice; Babanin, Alexander V.
Breaking probabilities and breaking wave height distributions (BWHDs) in deep, intermediate, and shallow water depth are compared, and a generic parameterization is proposed to represent the observed variability of breaking parameters as a function of the nondimensional water depth. In intermediate and deep water, where waves of different scales may have markedly different breaking probabilities, a BWHD as a function of wave frequency is proposed and validated with intermediate-depth and deep water observational data. The current study focuses on waves with frequencies between 0.55 and 3.45 times the peak frequency f(p). For the dominant frequency, the integration of the frequency-dependent BWHD provides a breaking probability that reproduces the known...

Provedor de dados: 5
Autores: Elfouhaily, Tanos; Chapron, Bertrand; Katsaros, Kristina; Vandemark, D.
Review of several recent ocean surface wave models finds that while comprehensive in many regards, these spectral models do not satisfy certain additional, but fundamental, criteria. We propose that these criteria include the ability to properly describe diverse fetch conditions and to provide agreement with in situ observations of Cox and Munk [1954] and Jahne and Riemer [1990] and Hara et al. [1994] data in the high-wavenumber regime. Moreover, we find numerous analytically undesirable aspects such as discontinuities across wavenumber limits, nonphysical tuning or adjustment parameters, and noncentrosymmetric directional spreading functions. This paper describes a two-dimensional wavenumber spectrum valid over all wavenumbers and analytically amenable to...

A unified spectral parameterization for wave breaking: From the deep ocean to the surf zone
Provedor de dados: 5
Autores: Filipot, Jean-francois; Ardhuin, Fabrice.
A new wave-breaking dissipation parameterization designed for phase-averaged spectral wave models is presented. It combines wave breaking basic physical quantities, namely, the breaking probability and the dissipation rate per unit area. The energy lost by waves is first explicitly calculated in physical space before being distributed over the relevant spectral components. The transition from deep to shallow water is made possible by using a dissipation rate per unit area of breaking waves that varies with the wave height, wavelength and water depth. This parameterization is implemented in the WAVEWATCH III modeling framework, which is applied to a wide range of conditions and scales, from the global ocean to the beach scale. Wave height, peak and mean...

A well-documented, publicly available, global data set of surface ocean carbon dioxide (CO2) parameters has been called for by international groups for nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) project was initiated by the international marine carbon science community in 2007 with the aim of providing a comprehensive, publicly available, regularly updated, global data set of marine surface CO2, which had been subject to quality control (QC). Many additional CO2 data, not yet made public via the Carbon Dioxide Information Analysis Center (CDIAC), were retrieved from data originators, public websites and other data centres. All data were put in a uniform format following a strict protocol. Quality control was carried out according to clearly...

A unifying quantitative framework for exploring the multiple facets of microbial biodiversity across diverse scales
Provedor de dados: 5
Autores: Escalas, Arthur; Bouvier, Thierry; Mouchet, Maud A.; Leprieur, Fabien; Bouvier, Corinne; Troussellier, Marc; Mouillot, David.
Recent developments of molecular tools have revolutionized our knowledge of microbial biodiversity by allowing detailed exploration of its different facets and generating unprecedented amount of data. One key issue with such large datasets is the development of diversity measures that cope with different data outputs and allow comparison of biodiversity across different scales. Diversity has indeed three components: local (), regional () and the overall difference between local communities (). Current measures of microbial diversity, derived from several approaches, provide complementary but different views. They only capture the component of diversity, compare communities in a pairwise way, consider all species as equivalent or lack a mathematically...

A unique in vivo experimental approach reveals metabolic adaptation of the probiotic Propionibacterium freudenreichii to the colon environment
Provedor de dados: 5
Autores: Saraoui, Taous; Parayre, Sandrine; Guernec, Gregory; Loux, Valentin; Montfort, Jerome; Le Cam, Aurelie; Boudry, Gaelle; Jan, G; Falentin, Helene.
Background  Propionibacterium freudenreichii is a food grade bacterium consumed both in cheeses and in probiotic preparations. Its promising probiotic potential, relying largely on the active release of beneficial metabolites within the gut as well as the expression of key surface proteins involved in immunomodulation, deserves to be explored more deeply. Adaptation to the colon environment is requisite for the active release of propionibacterial beneficial metabolites and constitutes a bottleneck for metabolic activity in vivo. Mechanisms allowing P. freudenreichii to adapt to digestive stresses have been only studied in vitro so far. Our aim was therefore to study P. freudenreichii metabolic adaptation to intra-colonic conditions in situ. Results  We...

A unique self-organization of bacterial sub-communities creates iridescence in Cellulophaga lytica colony biofilms
Provedor de dados: 5
Autores: Kientz, Betty; Luke, Stephen; Vukusic, Peter; Peteri, Renaud; Beaudry, Cyrille; Renault, Tristan; Simon, David; Mignot, Tam; Rosenfeld, Eric.
Iridescent color appearances are widespread in nature. They arise from the interaction of light with micron- and submicron-sized physical structures spatially arranged with periodic geometry and are usually associated with bright angle-dependent hues. Iridescence has been reported for many animals and marine organisms. However, iridescence has not been well studied in bacteria. Recently, we reported a brilliant “pointillistic” iridescence in colony biofilms of marine Flavobacteria that exhibit gliding motility. The mechanism of their iridescence is unknown. Here, using a multi-disciplinary approach, we show that the cause of iridescence is a unique periodicity of the cell population in the colony biofilm. Cells are arranged together to form hexagonal...

Autores: Beretta, Valentina; Desconnets, Jean-christophe; Mougenot, Isabelle; Arslan, Muhammad; Barde, Julien; Chaffard, Véronique.
The recent technological advancements and emergence of the open data in environmental and life sciences are opening new research opportunities while creating new challenges around data management. They make available an unprecedented amount of data that can be exploited for studying complex phenomena. However, new challenges related to data management need to be addressed to ensure effective data sharing, discovery and reuse, especially when dealing with interdisciplinary research contexts. These issues are magnified in interdisciplinary context, by the fact that each discipline has its practices, e.g., specific formats and metadata standards. Moreover, the majority of current data management practices do not consider semantic heterogeneity existing among...

A viscoelastic-viscoplastic model to describe creep and strain rate effects on the mechanical behaviour of adhesively-bonded assemblies
Provedor de dados: 5
Autores: Ilioni, Alin; Badulescu, C.; Carrere, N.; Davies, Peter; Thevenet, D.
Most of the adhesives used in the marine industry are polymers with a mechanical behaviour which is strongly influenced by the strain rate. Therefore, it is important to predict with accuracy their viscous behaviour. To describe their mechanical behaviour in a bonded joint, a viscoelastic-viscoplastic constitutive law is proposed here. The viscous effects on the elastic behaviour is described using a spectral distribution, which divides the viscous strain as the sum of the strains of several viscous mechanisms, each of them with a different characteristic time and weight. The viscoplastic component of the model permits a better description of the strong non-linear behaviour of the adhesives. The parameters of the constitutive law are obtained using an...

A walk down the Cap de Creus canyon, Northwestern Mediterranean Sea: Recent processes inferred from morphology and sediment bedforms
Provedor de dados: 5

The Cap de Creus canyon, northwestern Mediterranean Sea, belongs to a complex network of submarine canyons cutting the western Gulf of Lion continental shelf and opening into the larger Sete canyon. Swath bathymetry data, MAKAM deep-towed side-scan sonar imagery and 5 kHz high resolution seismic reflection profiles show striking morphologies in the Cap de Creus canyon floor and walls. As a consequence of the canyon head and the upper reach severe incision, the continental shelf dramatically narrows in front of the Creus Cape promontory. The upper canyon has a flat-bottomed thalweg incised in a megascale sediment furrow field displaying hyperbolic seismic facies. The tens of kilometres long linear furrows extend also over the middle canyon down to 1400 in...

A weekly Arctic sea-ice thickness data record from merged CryoSat-2 and SMOS satellite data
Provedor de dados: 5
Autores: Ricker, Robert; Hendricks, Stefan; Kaleschke, Lars; Tian-kunze, Xiangshan; King, Jennifer; Haas, Christian.
Sea-ice thickness on a global scale is derived from different satellite sensors using independent retrieval methods. Due to the sensor and orbit characteristics, such satellite retrievals differ in spatial and temporal resolution as well as in the sensitivity to certain sea-ice types and thickness ranges. Satellite altimeters, such as CryoSat-2 (CS2), sense the height of the ice surface above the sea level, which can be converted into sea-ice thickness. Relative uncertainties associated with this method are large over thin ice regimes. Another retrieval method is based on the evaluation of surface brightness temperature (TB) in L-band microwave frequencies (1.4 GHz) with a thickness-dependent emission model, as measured by the Soil Moisture and Ocean...

A Well-Kept Treasure at Depth: Precious Red Coral Rediscovered in Atlantic Deep Coral Gardens (SW Portugal) after 300 Years
Provedor de dados: 5
Autores: Boavida, Joana; Paulo, Diogo; Aurelle, Didier; Arnaud-haond, Sophie; Marschal, Christian; Reed, John; Goncalves, Jorge M. S.; Serrao, Ester A.
Background The highly valuable red coral Corallium rubrum is listed in several Mediterranean Conventions for species protection and management since the 1980s. Yet, the lack of data about its Atlantic distribution has hindered its protection there. This culminated in the recent discovery of poaching activities harvesting tens of kg of coral per day from deep rocky reefs off SW Portugal. Red coral was irregularly exploited in Portugal between the 1200s and 1700s, until the fishery collapsed. Its occurrence has not been reported for the last 300 years. Results Here we provide the first description of an Atlantic red coral assemblage, recently rediscovered dwelling at 60-100 m depth in southern Portugal. We report a very slow growth rate (0.23 mm year-1),...

[1] The equatorial Pacific and Atlantic oceans exhibit remarkable meridional undulations in temperature and chlorophyll fronts visible from space over thousands of kilometers and often referred to as tropical instability waves. Here, we present new observations of an ecosystem ranging through three trophic levels: phytoplankton, zooplankton and small pelagic fish whirling within a tropical vortex of the Atlantic ocean and associated with such undulations. Cold, nutrient and biologically rich equatorial waters are advected northward and downward to form sharp fronts visible in all tracers and trophic levels. The equatorward recirculation experiences upwelling at depth, with the pycnocline and ecosystem progressively moving toward the surface to reconnect...

A white spot disease-like syndrome in the Pacific blue shrimp (Litopenaeus stylirostris) as a form of bacterial shell disease
Provedor de dados: 5
Autores: Goarant, Cyrille; Brizard, Raphael; Marteau, Anne-laure.
In May 1997, some white lesions evoking the white spot syndrome disease were observed in Litopenaeus stylirostris broodstock in New Caledonia. The occurrence of these lesions was neither associated with mortality, nor with histological evidence of white spot syndrome baculovirus (WSBV), The evidence suggests that these lesions result from a form of bacterial disease and are associated with an increased bacterial flora on the outer surface of the cuticle, as well as an increased incidence throughout the molt cycle. A microscopic observation of these lesions allows them to be differentiated from WSBV-associated lesions.

A World for Reactive Phenotypes
Provedor de dados: 5
Autores: Geoffroy, Benjamain; Alfonso, Sebastien; Sadoul, Bastien; Blumstein, Daniel T.
Humans currently occupy all continents and by doing so, modify the environment and create novel threats to many species; a phenomenon known as human-induced rapid environmental changes (HIREC). These growing anthropogenic disturbances represent major and relatively new environmental challenges for many animals, and invariably alter selection on traits adapted to previous environments. Those species that survive often have moved from their original habitat or modified their phenotype through plasticity or genetic evolution. Based on the most recent advances in this research area, we predict that wild individuals with highly plastic capacities, relatively high basal stress level, and that are generally shy—in other words, individuals displaying a reactive...

Autores: Fonteneau, Alain; Pallares, P; Pianet, Renaud.
This paper develops a comparative overview of the development of Fish Aggregating Devices (or fads) by the tropical purse seine fisheries in various ocean areas (Atlantic, Indian, Western and Eastern Pacific Oceans). First, a comparative review of fishery statistics is developed. Recent catches on fads by purse seiners can be estimated at a level of one million tons yearly. This comparison allows to describe the fishing zones and catch trends over time, the species composition and size taken in the various fad fisheries. Skipjack tuna is the dominant species in most fad fisheries, but significant amounts of yellowfin and bigeye are also frequently taken under fads. The paper also presents an overview of various observer data concerning the by-catches of...

A year-class curve analysis to estimate mortality of Atlantic bluefin tuna caught by the Norwegian fishery from 1956 to 1979
Provedor de dados: 5
Autores: Fromentin, Jean-marc; Restrepo, Victor.
At the ICCAT symposium on bluefin tuna that held in Santander in April 2008, Tangen et al.(2009) presented a first quantification of the fishing effort deployed by the Norwegian fishery targeting bluefin tuna in the North Sea and Norwegian Sea. Using a year-class curve analysis on the Norwegian CPUE, this document presents the first estimates of mortality rates of Atlantic bluefin tuna that migrated north from the mid-1950s to the late 1970s. The results indicate that bluefin tuna would have experienced a total mortality rate (Z) of 0.2 to 0.4 yr-1 (i.e. F at around 0.3 yr-1) during the late 1950s, 0.2 yr-1 during the 1960s and 0.1 yr-1 afterwards (assuming M=0.1 yr-1). These results appear to be rather robust and consistent with the VPA estimates from the...

The coastal marsh of Kervigen is located near by the bay of Douarnenez and its 22 hectares are almost entirely covered by reeds. An experiment was there carried out to assess the nitrogen flux depletion of a small stream, the Kerharo. That one has a 45 km 2 mostly agricultural drainage basin. Due to its nitrate loadings to the next sandy beach, it feeds a green algae (Ulva) proliferation. In order to control its nitrogen fluxes, the stream was partly diverted through a part of the marsh (9 ha), before it was allowed to go back to the main bed. Thus a collapsible weir was set up during several springs and summers, i.e. the growing period of Ulva. The nitrate stripping off the going through flux is within a 30 to 90 % range,that is important (175 kg N03...

Début 1990, l'IFREMER et les Affaires Maritimes sont contactés par un ostréiculteur de l'Aber-Benoit afin d'effectuer le constat de mortalités survenues depuis 1989 sur ses concessions. L'expertise révèle des taux de mortalité allant de 20 à 70% sur les huîtres en élevage, tous âges et toutes techniques confondues (Cl. Le Bec, 1989). Dès cette date, un gradient décroissant de mortalité est noté d'amont en aval et du chenal à la berge. Ces mortalités anormales, par comparaison avec les autres bassins ostréicoles bretons, sont également observées sur les poches expérimentales des stations de l'Aber Benoit du réseau "Huître Creuse Bretagne" (C.

Ability of spatial indicators to detect geographic changes (shift, shrink and split) across biomass levels and sample sizes
Provedor de dados: 5
Autores: Rufino, Marta; Bez, Nicolas; Brind'Amour, Anik.
Spatial indicators are widely used to monitor species and are essential to management and conservation. In the present study, we tested the ability of 11 spatial indicators to quantify changes in species’ geographic patterns: (1) spatial displacement of a patch of biomass (‘shift’), (2) a spatial decrease in a patch, accompanied either by a loss of biomass (‘shrink0’) or (3) a relocation of the same biomass (‘shrink1’), and (4) splitting of a patch into smaller patches (‘split’). The geographic changes were simulated by manipulating the spatial distributions of the demersal species (observed during bottom trawl surveys). Hence, the spatial distributions of the latter being used as input data on which the manipulations were done. Additionally, other aspects...

Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication levels and aquaculture intensity. Based on macrophyte communities associated with soft substrates, two indices of taxonomic diversity (the "average taxonomic distinctness" (Delta(+)) and the "variation in taxonomic distinctness" (Lambda(+))) were used to discriminate four of these lagoons (Thau, Salse-Leucate, Bages-Sigean and Mauguio). Bages-Sigean presented a significant higher average taxonomic distinctness (p &lt; 0.05) and Salse-Leucate had a significant higher variation in taxonomic distinctness (p &lt;...

Abiotic stress protection by ecologically abundant dimethylsulfoniopropionate and its natural and synthetic derivatives: insights from   B   acillus subtilis

Dimethylsulfoniopropionate (DMSP) is an abundant osmolyte and anti-stress compound produced primarily in marine ecosystems. After its release into the environment, microorganisms can exploit DMSP as a source of sulfur and carbon, or accumulate it as an osmoprotectant. However, import systems for this ecophysiologically important compatible solute, and its stress-protective properties for microorganisms that do not produce it are insufficiently understood. Here we address these questions using a well-characterized set of Bacillus subtilis mutants to chemically profile the influence of DMSP import on stress resistance, the osmostress-adaptive proline pool and on osmotically controlled gene expression. We included in this study the naturally occurring...

Abnormal periostracum secretion during the mineralization process of the pearl in the blacklip pearl oyster Pinctada margaritifera
Provedor de dados: 5
Autores: Comps, Marie-annick; Herbaut, Christian; Fougerouse, Angélique.
Whitish parasite-like bodies (PLBs), 0.5-2 mu m in size, were detected within the pearl bag of some grafted pearl oysters, Pinctada margaritifera, from Takapoto island (French Polynesia). Histological and ultrastructural investigations have revealed that these bodies consisted of lamellar organic material locally secreted by some epithelial cells of the pearl bag. The fine structure and the formation of these bodies are described. The causes of this abnormal secretion of organic mater, which actually corresponds to periostracum, are not presently known. No parasite nor infectious micro-organism was found associated with the PLBs.

This paper presents the results obtained about the larvae of three commercial brachyuran decapoda species : the Velvet Swiming crab (Macropipus puber, L.), the Spinous Spider Crab (Maia squinado Herbst) and the Edible Crab (Cancer pagurus, L.). For the three annual cycles considered saisonal variations in abundance of zoeal and megalopa stages were represented. For the 1978 and 1979 samples we made, in addition, the distinction between the successive zoeal stages....

In the context of WFD implementation on Mediterranean lagoons, work has been carried out since 2010 by Ifremer, Tour du Valat and IRSTEA (Onema and AERM &amp; C fundings), to assess the relevance of macrophytes and macrofauna indicators for oligohaline and mesohaline lagoons (mean salinity &lt;18 PSU). The question of the relevance of indicator metrics and thresholds for the "phytoplankton" biological quality element also arises, especially due to the confined nature of olgo-mesohaline lagoons. The objective of this study is to characterize the abundance and composition of phytoplankton on 5 oligo and mesohaline lagoons of the French Mediterranean coast (Scamandre, Crey, Charnier, Bolmon and Grand Palun). Analyses of accessory pigments (chlorophyll and...

About frame estimation of growth functions and robust prediction in bioprocess modeling
Provedor de dados: 5
Autores: Krichen, Emna; Rapaport, A.; Fouilland, Eric.
We address the problem of determining functional framing from experimental data points in view of robust time-varying predictions, which is of crucial importance in bioprocess monitoring. We propose a method that provides guaranteed functional bounds, instead of sets of parameters values for growth functions such as the classical Monod or Haldane functions commonly used in bioprocess modeling. We illustrate the applicability of the method with bioreactor simulations in batch and continuous mode, as well as on real data. We also present two extensions of the method adding flexibility in its application, and discuss its efficiency in providing guaranteed state estimations.

Autores: García-martínez, María Del Carmen; Vargas-yáñez, Manuel; Moya, Francina; Zunino Rodriguez, Patricia; Bautista, Begoña.
The Mediterranean Sea transforms Atlantic Waters inflowing through the Strait of Gibraltar into saltier, cooler and denser Mediterranean Waters that outflow into the Atlantic Ocean. A theoretical steady state functioning of the Mediterranean Sea would be the result of the balance between the net heat and volume transports through the Strait of Gibraltar and the heat loss to the atmosphere through the sea surface and the net evaporation. The salt transport for the inflow and outflow should be balanced. Changes in the heat content, temperature and salinity of the Mediterranean waters reveal that the present Mediterranean functioning is out of this equilibrium state. A new analysis for MEDAR data shows that the temperature and salinity averaged for the...

Abrupt changes in the characteristics of atlantic and levantine intermediate waters in the southeastern levantine basin
Provedor de dados: 5
Autores: Hecht, A.
Data from twenty consecutive cruises, carried out over a period of five years, were investigated in order to reveal temporal changes in the characteristics of the AW (Atlantic Waters) and the LIW (Levantine Intermediate Waters) in the Southeastern Levantine basin. The results indicated a seasonal trend in the AW, which appear to be poorly defined during winter and spring but which, as the year progresses and as the LSW (Levantine Surface Waters) form and penetrate downward, become better defined, and occupy a narrower layer whose depth increases. There appeared to be no season related variations in the LIW. Moreover, abrupt, significant, and apparently irreversible changes in the characteristic salinity of the AW and the LIW occurred in the Southeastern...

Millennial-scale variability in the behavior of North Pacific Intermediate Water during the last glacial and deglacial period, and its association with Dansgaard-Oeschger (D-O) cycles and Heinrich events, are examined based on benthic foraminiferal oxygen and carbon isotopes (delta O-18(bf) and delta C-13(bf)) and %CaCO3 using a sediment core recovered from the northeastern slope of the Bering Sea. A suite of positive delta O-18(bf) excursions at intermediate depths of the Bering Sea, which seem at least in part associated with increases in the delta O-18(bf) gradients between the Bering and Okhotsk Seas, suggest the Bering Sea as a proximate source of intermediate water during several severe stadial episodes in the last glacial and deglacial period....

Autores: Bahr, Andre; Lamy, Frank; Arz, Helge W.; Major, Candace; Kwiecien, Olga; Wefer, Gerold.
[1] New Mg/Ca, Sr/Ca, and published stable oxygen isotope and Sr-87/(86) Sr data obtained on ostracods from gravity cores located on the northwestern Black Sea slope were used to infer changes in the Black Sea hydrology and water chemistry for the period between 30 to 8 ka B. P. ( calibrated radiocarbon years). The period prior to 16.5 ka B. P. was characterized by stable conditions in all records until a distinct drop in delta O-18 values combined with a sharp increase in Sr-87/(86) Sr occurred between 16.5 and 14.8 ka B. P. This event is attributed to an increased runoff from the northern drainage area of the Black Sea between Heinrich Event 1 and the onset of the Bolling warm period. While the Mg/Ca and Sr/Ca records remained rather unaffected by this...

Abrupt climate changes for Iceland during the last millennium: Evidence from high resolution sea ice reconstructions
Provedor de dados: 5
Autores: Masse, Guillaume; Rowland, Steven J.; Sicre, Marie-alexandrine; Jacob, Jeremy; Jansen, Eystein; Belt, Simon T.
A high resolution account of Icelandic sea ice over the last millennium has been constructed using a novel proxy based on the presence in sediments of a biomarker (IP25) produced by sea ice algae. Comparison with historical sea ice records demonstrates a strong correlation between documented sea ice Occurrences and the IP25 proxy. An excellent agreement is also observed between the IP25 record and a diatom-based sea surface temperature reconstruction obtained from the same core and the Crowley and Lowery Northern Hemisphere temperature reconstruction. Using this approach, we provide new historical sea ice data for periods where records are scarce or absent and evidence for abrupt changes to sea ice and/or climate conditions around Iceland during the Little...

Abrupt changes in Western Mediterranean climate during the last deglaciation (20 to 6 cal ka BP) are detected in marine core MD95-2043 (Alboran Sea) through the investigation of high-resolution pollen data and pollen-based climate reconstructions by the modern analogue technique (MAT) for annual precipitation (P-ann) and mean temperatures of the coldest and warmest months (MTCO and MTWA). Changes in temperate Mediterranean forest development and composition and MAT reconstructions indicate major climatic shifts with parallel temperature and precipitation changes at the onsets of Heinrich stadial 1 (equivalent to the Oldest Dryas), the Bolling-Allerod (BA), and the Younger Dryas (YD). Multi-centennial-scale oscillations in forest development occurred...

Abrupt climate variability during the last glacial and the late Holocene from the western tropical Pacific perspective
Provedor de dados: 5
Autores: Saikku, Reetta Maaria.
In Project I, Western tropical Pacific sea surface temperatures and Pacific Deep Water temperatures during Marine Isotope Stage 3 have been reconstructed from the δ18O and Mg/Ca of planktonic and benthic foraminifera from Marion Dufresne core MD98-2181. This 36m marine core was collected at 6.3°N from a water depth of 2114m. With sediment accumulation rates of up to 80cm/ky, it provides a decadally-resolved history of ocean variability during the last glacial period. Surface temperatures and salinities at this site varied in close association with millennial-scale atmospheric temperature swings at high northern latitudes as reflected in the GISP2 ice core. At times of colder atmospheric temperatures over Greenland, the western Pacific was more saline and...

Autores: Soulet, Guillaume; Menot, Guillemette; Bayon, Germain; Rostek, Frauke; Ponzevera, Emmanuel; Toucanne, Samuel; Lericolais, Gilles; Bard, Edouard.
Continental ice sheets are a key component of the Earth’s climate system, but their internal dynamics need to be further studied. Since the last deglaciation, the northern Eurasian Fennoscandian Ice Sheet (FIS) has been connected to the Black Sea (BS) watershed, making this basin a suitable location to investigate former ice-sheet dynamics. Here, from a core retrieved in the BS, we combine the use of neodymium isotopes, high-resolution elemental analysis, and biomarkers to trace changes in sediment provenance and river runoff. We reveal cyclic releases of meltwater originating from Lake Disna, a proglacial lake linked to the FIS during Heinrich Stadial 1. Regional interactions within the climate–lake–FIS system, linked to changes in the availability of...

Abrupt response of chemical weathering to Late Quaternary hydroclimate changes in northeast Africa
Provedor de dados: 5
Autores: Bastian, Luc; Revel, Marie; Bayon, Germain; Dufour, Aurelie; Vigier, Nathalie.
Chemical weathering of silicate rocks on continents acts as a major sink for atmospheric carbon dioxide and has played an important role in the evolution of the Earth’s climate. However, the magnitude and the nature of the links between weathering and climate are still under debate. In particular, the timescale over which chemical weathering may respond to climate change is yet to be constrained at the continental scale. Here we reconstruct the relationships between rainfall and chemical weathering in northeast Africa for the last 32,000 years. Using lithium isotopes and other geochemical proxies in the clay-size fraction of a marine sediment core from the Eastern Mediterranean Sea, we show that chemical weathering in the Nile Basin fluctuated in parallel...

Autores: Chevillot, Xavier; Pierre, Maud; Rigaud, Arthur; Drouineau, Hilaire; Chaalali, Aurelie; Sautour, Benoit; Lobry, Jeremy.
For decades, global climate change has directly and indirectly affected the structure and function of ecosystems. Abrupt changes in biodiversity have been observed in response to linear or sudden modifications to the environment. These abrupt shifts can cause long-term reorganizations within ecosystems, with communities exhibiting new functional responses to environmental factors. Over the last 3 decades, the Gironde estuary in southwest France has experienced 2 abrupt shifts in both the physical and chemical environments and the pelagic community. Rather than describing these shifts and their origins, we focused on the 3 inter-shift periods, describing the structure of the fish community and its relationship with the environment during these periods. We...

Relict dune fields that are found as far south as 14 N in the modern-day African Sahel are testament to equatorward expansions of the Sahara desert during the Late Pleistocene. However, the discontinuous nature of dune records means that abrupt millennial-timescale climate events are not always resolved. High-resolution marine core studies have identified Heinrich stadials as the dustiest periods of the last glacial in West Africa although the spatial evolution of dust export on millennial timescales has so far not been investigated. We use the major-element composition of four high-resolution marine sediment cores to reconstruct the spatial extent of Saharan-dust versus river-sediment input to the continental margin from West Africa over the last 60 ka....

A detailed assessment of the respective roles of production, export, and subsequent preservation of organic carbon (C-org) in the eastern Mediterranean (EMED) sediments during the formation of sapropels remains elusive. Here we present new micropaleontological results for both surface samples taken at several locations in the EMED and last interglacial sapropel S5 from core LC21 in the southeastern Aegean Sea. A strong exponential anticorrelation between relative abundances of the lower photic zone coccolithophore Florisphaera profunda in the surface sediments and modern concentrations of chlorophyll a (Chl-a) at the sea surface suggests that F. profunda percentages can be used to track past productivity changes in the EMED. Prior to S5 deposition, an...

The Mediterranean Sea is a hotspot for climate change, and recent studies have reported its intense warming and salinification. In this study, we use an outstanding dataset relying mostly on glider endurance lines but also on other platforms to track these trends in the northwestern Mediterranean where deep convection occurs. Thanks to a high spatial coverage and a high temporal resolution over the period 2007–2017, we observed the warming (+0.06 ∘C year−1) and salinification (+0.012 year−1) of Levantine Intermediate Water (LIW) in the Ligurian Sea. These rates are similar to those reported closer to its formation area in the Eastern Mediterranean Sea. Further downstream, in the Gulf of Lion, the intermediate heat and salt content were exported to the deep...

AB_SA: Accessory genes-Based Source Attribution – tracing the source of Salmonella enterica Typhimurium environmental strains

Autores: Guillier, Laurent; Gourmelon, Michele; Lozach, Solen; Cadel-six, Sabrina; Vignaud, Marie-léone; Munck, Nanna; Hald, Tine; Palma, Federica.
The partitioning of pathogenic strains isolated in environmental or human cases to their sources is challenging. The pathogens usually colonize multiple animal hosts, including livestock, which contaminate the food-production chain and the environment (e.g. soil and water), posing an additional public-health burden and major challenges in the identification of the source. Genomic data opens up new opportunities for the development of statistical models aiming to indicate the likely source of pathogen contamination. Here, we propose a computationally fast and efficient multinomial logistic regression source-attribution classifier to predict the animal source of bacterial isolates based on ‘source-enriched’ loci extracted from the accessory-genome profiles...

Absence de captage de Crassostrea gigas dans le bassin de Marennes-Oléron en 1981 : causes et conséquences
Provedor de dados: 5
Autores: Berthome, Jean-paul; Deslous-paoli, Jean-marc; Heral, Maurice; Razet, Daniel; Garnier, Jacqueline.
The want of C. gigas spat-catching in the Marennes-oleron basin in 1981 can be due to various different reasons which are analysed here. Physico -chemical and trophic factors that can induce variations in the quality of gametogenesis, are successively in comparison with the year 1979 when reproduction was good. The biochemical evolution and a study of gonads slow a lack in maturation in 1981 even during the summer period. Late maturation of gonads bring about physiological consequences which induced mortality of cultivated oysters at the end of winter. A feeble recruit and a decrease of the cultivated stock have economic consequences which here sketched up.

The common dentex, Dentex dentex, is a fish species which inhabits marine environments in the Mediterranean and Northeast Atlantic regions. This is an important species from an ecological, economic and conservation perspective, however critical information on its population genetic structure is lacking. Most samples were obtained from the Mediterranean Sea (17 sites) with an emphasis around Corsica (5 sites), plus one Atlantic Ocean site. This provided an opportunity to examine genetic structuring at local and broader scales to provide science based data for the management of fishing stocks in the region. Two mitochondrial regions were examined (D-loop and COI) along with eight microsatellite loci. The COI data was combined with publicly available...

Absolute magnetization of the seafloor at a basalt-hosted hydrothermal site: Insights from a deep-sea submersible survey
Provedor de dados: 5
Autores: Szitkar, Florent; Dyment, Jerome; Fouquet, Yves; Choi, Yujin; Honsho, Chie.
The analysis of high-resolution vector magnetic data acquired by deep-sea submersibles (DSSs) requires the development of specific approaches adapted to their uneven tracks. We present a method that takes advantage of (1) the varying altitude of the DSS above the seafloor and (2) high-resolution multibeam bathymetric data acquired separately, at higher altitude, by an Autonomous Underwater Vehicle, to estimate the absolute magnetization intensity and the magnetic polarity of the shallow subseafloor along the DSS path. We apply this method to data collected by DSS Nautile on a small active basalt-hosted hydrothermal site. The site is associated with a lack of magnetization, in agreement with previous findings at the same kind of sites: the contrast between...

Autores: Bidel, Y.; Zahzam, N.; Blanchard, C.; Bonnin, A.; Cadoret, M.; Bresson, A.; Rouxel, D.; Lequentrec-lalancette, M. F.
Measuring gravity from an aircraft or a ship is essential in geodesy, geophysics, mineral and hydrocarbon exploration, and navigation. Today, only relative sensors are available for onboard gravimetry. This is a major drawback because of the calibration and drift estimation procedures which lead to important operational constraints. Atom interferometry is a promising technology to obtain onboard absolute gravimeter. But, despite high performances obtained in static condition, no precise measurements were reported in dynamic. Here, we present absolute gravity measurements from a ship with a sensor based on atom interferometry. Despite rough sea conditions, we obtained precision below 10−5 m s−2. The atom gravimeter was also compared with a commercial spring...

Absorption et régénération de l'azote dans la zone frontale du courant Algérien (Méditerranée Occidentale) : réévaluation de la production nouvelle
Provedor de dados: 5
Autores: Gentilhomme, V; Raimbault, P.
The uptake and regeneration of four forms of nitrogen NO3-, NO2-, NH4+ and urea) have been studied, in the euphotic layer of a frontal area (Algerian current), in relation with hydrological, chemical and biological parameters. Ln this area vertical stratification is pronounced; a deep chlorophyll maximum at the bottom of the euphotic layer is present. Results show the importance of measuring urea uptake and regeneration in the study of nitrogen cycling, because this component can be regenerated as rapidly as ammonia, and is a source of nitrogen for phytoplankton. Other results show the oxidation of ammonia to nitrate in the euphotic layer, and particularly at the base of this layer. This nitrification is a source of in situ regenerated nitrate, and could...

Absorption et régénération de l'azote dans le système brassé de la Manche : productions nouvelle et régénérée
Provedor de dados: 5
Autores: Maguer, Jf; L'Helguen, S; Madec, C; Le Corre, P.
Nitrate and ammonium uptake rates were measured in spring and summer in deep and shallow well-mixed waters of the English Channel during different cruises between 1986 and 1994. In the deep waters, nitrate uptake was relatively low during phytoplankton development and ammonium uptake represented more than 70 % of the total uptake irrespective of the season. In the shallow waters, nitrate uptake during spring phytoplankton growth was high and represented about 75 % of the total uptake. Ammonium uptake became substantial towards the end of spring and summer. The high contribution of ammonium to the nitrogenous nutrition of phytoplankton over the whole of the well-mixed waters is related to a high rate of recycling of nitrogen in the water column. Ammonium...

Absorption et régénération de l'azote dans les écosystèmes côtiers ; relations avec le régime de mélange vertical des masses d'eaux ; cas du domaine homogène peu profond de la Manche Occidentale.
Provedor de dados: 5
Autores: Maguer, Jean-francois.
La production primaire dans l'océan est généralement limitée par l'azote. Ceci a été mis en évidence dans le domaine océanique (Thomas, 1966 ; 1969 ; Eppley et al., 1973) et dans les eaux côtières (Ryther et Dunstan, 1971 ; McCarthy et al., 1977). Par ailleurs, dans l'eau de mer, les cycles biogéochimiques des principaux éléments (C, N, P) sont étroitement liés (Redfield et al., 1963) et l'azote, en contrôlant la production primaire, règle pour une large part les flux des différents composés. Il régule en particulier les flux de carbone dans la zone euphotique et vers les couches profondes, déterminant ainsi la capacité des écosystèmes à exporter la matière organique.

Abundance and diversity of Planctomycetes in a Tyrrhenian coastal system of central Italy
Provedor de dados: 5
Autores: Pizzetti, Ilaria; Gobet, Angelique; Fuchs, Bernhard M.; Amann, Rudolf; Fazi, Stefano.
The phylum Planctomycetes is involved in important processes, such as the mineralization of algal biomass and the removal of nitrogen. Using a combination of 16S rRNA sequence analysis and in situ hybridization, we analyzed the diversity and dynamics of Planctomycetes in a shallow meso-eutrophic lake, Lago di Paola, Italy. Planctomycetes detected by the probe PLA46 accounted for 1 to 5% of prokaryotic picoplankton. Abundances were higher in the coastal lake than in the adjacent marine waters. In the surface waters of the lake, the numbers of Planctomycetes fluctuated greatly, reaching a maximum of 1.5 x 10(6) cells ml(-1) in July. The hypoxic bottom waters had less variable cell abundances. The Planctomycetes counts were positively correlated with...

Abundance estimate and seasonal patterns of grey seal (Halichoerus grypus) occurrence in Brittany, France, as assessed by photo-identification and capture-mark-recapture
Provedor de dados: 5
Autores: Gerondeau, M; Barbraud, C; Ridoux, Vincent; Vincent, Cecile.
It has been suggested that the large grey seal colonies around the British Isles form local populations within a metapopulation, and that seal movements outside the breeding season lead to considerable overlap between individual home ranges. Individual behaviour and population dynamics of small peripheral colonies may also play a role in the metapopulation. We studied the French grey seal colony of the Molene archipelago, at the southern-most limit of the species' range. We analysed photo-identification data with capture-mark-recapture techniques in order to estimate the total seasonal abundance of grey seals in the archipelago and to quantify the seasonal rates of occurrence or movements of male and female seals. We found that between 58% (95% confidence...

Bathymodiolus mussels live in symbiosis with intracellular sulfur-oxidizing (SOX) bacteria that provide them with nutrition. We sequenced the SOX symbiont genomes from two Bathymodiolus species. Comparison of these symbiont genomes with those of their closest relatives revealed that the symbionts have undergone genome rearrangements, and up to 35% of their genes may have been acquired by horizontal gene transfer. Many of the genes specific to the symbionts were homologs of virulence genes. We discovered an abundant and diverse array of genes similar to insecticidal toxins of nematode and aphid symbionts, and toxins of pathogens such as Yersinia and Vibrio. Transcriptomics and proteomics revealed that the SOX symbionts express the toxin-related genes (TRGs)...

Abyssal hill characterization at the ultraslow spreading Southwest Indian Ridge
Provedor de dados: 5
Autores: Sloan, Heather; Sauter, Daniel; Goff, John A.; Cannat, Mathilde.
The morphology of the flanks of the Southwest Indian Ridge holds a record of seafloor formation and abyssal hill generation at an ultraslow spreading rate. Statistical analysis of compiled bathymetry and gravity data from the flanks of the Southwest Indian Ridge from 54 degrees E to 67 degrees E provides estimates of abyssal hill morphologic character and inferred crustal thickness. The extent of the compiled data encompasses a spreading rate change from slow to ultraslow at similar to 24 Ma, a significant inferred variation in sub-axis mantle temperature, and a patchwork of volcanic and non-volcanic seafloor, making the Southwest Indian Ridge an ideal and unique location to characterize abyssal hills generated by ultraslow spreading and to examine the...

Accelerated ageing and lifetime prediction of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in distilled water
Provedor de dados: 5
Autores: Deroine, Morgan; Le Duigou, Antoine; Corre, Yves-marie; Le Gac, Pierre-yves; Davies, Peter; Cesar, Guy; Bruzaud, Stephane.
Accelerated ageing was performed in distilled water at different temperatures (25, 30, 40 and 50°C) on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), which is a biodegradable biopolymer, in order to estimate its lifetime in aqueous environment. In a first part, degradation mechanisms were followed by gravimetry, tensile tests and steric exclusion chromatography. Both immersion and relative humidity have been examined. In a second part, the strain at break was used as an indicator for lifetime prediction with an Arrhenius extrapolation. The study revealed the presence of only one irreversible degradation mechanism, i.e. hydrolytic degradation, which is temperature dependant. So, within the approach assumptions, the lifetime in distilled water of PHBV...

Pollution of nature by plastics is a major environmental problem and the challenge for the future is to manage the lifetime of polymers better. The aim of this study is to establish a baseline on degradation mechanism and degradation kinetics for lifetime prediction of polylactide (PLA) in a marine environment. The ageing of PLA was accelerated by raising temperature in distilled water, filtered and renewed seawater and natural seawater. Samples were immersed in distilled water for six months at different temperatures (25, 30, 40 and 50°C) in order to evaluate the influence of temperature on PLA degradation kinetics and to predict lifetime. Then, samples were immersed in seawater both in the laboratory and at sea, in order to compare the effects of...

Accelerated ageing of polyurethanes for marine applications
Provedor de dados: 5
Autores: Davies, Peter; Evrard, Guy.
Polyurethanes are frequently used in underwater applications. They are required to resist the marine environment over long periods of immersion but the multiplicity of resin formulations makes material selection difficult. Accelerated tests are essential to guarantee long term integrity. This paper presents results from an experimental study in which polyurethane samples of two hardnesses, 40 and 90 Shore A, have been subjected to immersion in artificial sea water for periods up to two years at temperatures from 50 to 100 degrees C. In parallel samples have been immersed at sea in the Brest Estuary for up to five years. Mechanical properties have been measured on tensile specimens after ageing. The accelerated test results and FTIR analysis indicate that...

Acceleration Performance of Individual European Sea Bass Dicentrarchus labrax Measured with a Sprint Performance Chamber: Comparison with High-Speed Cinematography and Correlates with Ecological Performance
Provedor de dados: 5
Autores: Vandamm, Joshua P.; Marras, Stefano; Claireaux, Guy; Handelsmank, Corey A.; Nelson, Jay A.
Locomotor performance can influence the ecological and evolutionary success of a species. For fish, favorable outcomes of predator-prey encounters are often presumably due to robust acceleration ability. Although escape-response or "fast-start" studies utilizing high-speed cinematography are prevalent, little is known about the contribution of relative acceleration performance to ecological or evolutionary success in a species. This dearth of knowledge may be due to the time-consuming nature of analyzing film, which imposes a practical limit on sample sizes. Herein, we present a high-throughput potential alternative for measuring fish acceleration performance using a sprint performance chamber (SPC). The acceleration performance of a large number of...

Acclimatation du clam (Venus mercenaria L.) en Bretagne
Provedor de dados: 5
Autores: Marteil, Louis.
Large quantities of clams (Venus mercenaria L.) from the U.S.A. have been introduced in Brittany since 1930. Stopped in 1940, their importation started again in 1954. These shellfishes, designed to be immediately sold for eating, only stayed for a short period of time in the ponds and farms of the Belon, Pénerf and Etel rivers, or in the Gulf of Morbihan, where they were stocked. However, some individuals managed to escape the fisheries and stayed buried for years where they had been sown. Lambert (1949) reported how some twenty year-old clams were found on a farm on the Etel River. In some ponds of the Gulf of Morbihan and the Pénerf river, one can still find clams which have been stocked there before 1940: their size is huge and reaches 10 to 14 cm, and...

Acclimation of the marine diatom Pseudo‐nitzschia australis to different salinity conditions: effects on growth, photosynthetic activity and domoic acid content
Provedor de dados: 5
Autores: Ayache, Nour; Hervé, Fabienne; Lundholm, Nina; Amzil, Zouher; Caruana, Amandine.
oxic Pseudo‐nitzschia australis strains isolated from French coastal waters were studied to investigate their capacity to adapt to different salinities. Their acclimation to different salinity conditions (10, 20, 30, 35 and 40) was studied on growth, photosynthetic capacity, cell biovolume and domoic acid (DA) content. The strains showed ability to acclimate to a salinity range from 20 to 40, with optimal growth rates between salinities 30 and 40. The highest cell biovolume was observed at the lowest salinity 20 and was associated with the lowest growth rate. Salinity did not affect the photosynthetic activity; Fv/Fm values and the pigment contents remained high with no significant difference among salinities. An enhanced production of zeaxanthin was,...

Account of ambient turbulence for turbine wakes using a Synthetic-Eddy-Method
Provedor de dados: 5
Autores: Pinon, Gregory; Carlier, Clement; Fur, Arnaud; Gaurier, Benoit; Germain, Gregory; Riyoalen, Elie.
The present paper aims at describing the use of a Synthetic-Eddy-Method (SEM), initially proposed by Jarrin et al. [12], in the 3D Lagrangian Vortex method framework. The SEM method is used here in order to generate a far-field incoming flow with a prescribed ambient turbulence intensity. However, for the account of the diffusive term in the Navier-Stokes equations, a classical Particle Strength Exchange model with a LES eddy viscosity is used. Firstly, the general characteristics of the Synthetic-Eddy-Method will be presented together with its integration in the framework of the developed 3D unsteady Lagrangian Vortex software [27]. The capability of the ambient turbulence model to reproduce a perturbed flow that verifies any turbulence intensity I∞ and...

Marine resources stewardships are progressively becoming more receptive to an effective incorporation of both ecosystem and environmental complexities into the analytical frameworks of fisheries assessment. Understanding and predicting marine fish production for spatially and demographically complex populations in changing environmental conditions is however still a difficult task. Indeed, fisheries assessment is mostly based on deterministic models that lack realistic parameterizations of the intricate biological and physical processes shaping recruitment, a cornerstone in population dynamics. We use here a large metapopulation of a harvested fish, the European hake (Merluccius merluccius), managed across transnational boundaries in the northwestern...

Accounting for Rough Bed Friction Factors of Mud Beds as a Result of Biological Activity in Erosion Experiments
Provedor de dados: 5
Autores: Guizien, Katell; Orvain, Francis; Duchene, Jean-claude; Le Hir, Pierre.
The average bed shear stress and bed friction factor of samples with any roughness was derived from the head loss between upstream and downstream of a test section in an erosion tunnel. The method was validated in both hydraulically smooth (plexiglass; Reynolds number less than 25,000) and rough regimes (calibrated particles with known roughness). As a first step toward using this method on natural sediment, this method was tested with experimental mesocosms assembled from field collected materials (sieved sediments; diatoms). Bed shear stress measurement precision was high enough in the experiments to detect a positive significant relationship between bed friction factor and core roughness. The observed bed friction factor increase could be related to...

Autores: Girin, Michel; Metailler, Robert; Nedelec, Jacqueline.
A comparative test of various inert diets was performed on 9 batches of 150 one month old soles, wheighing an average 42 mg, and feeding on live brine shrimps. It lasted for 2 months, in 60 l square tanks, with sand bottoms. . A succession of frozen natural feed, ending with the Bivalve Laevioardium arassum, was compared to 2 different artificial diets, offered as dry pellets. The inurement to the pellets was facilitated by an incorporation of various meals, used as flavourings, during a 6 weeks transitory period. - At the end of the experiment, the best result, 98 % survival, average weight . 1.10 g, was obtained with the natural feed. The best flavourings for dry pellets were Laevi- cardium arassum and the Polyahaete Nephthus hombergii, with 70 %...

Seismic, Seabeam, magnetic and gravimetrie surveys in the southern part of the N-Fiji basin were conducted during the SEAPSO LEG III Cruise. The active spreading axis was recognized between 17°30'S and 21°S. It consists of a continuous N-S Ridge cross-cut by transverse directions oriented N25 and N45. North of 17°30'S, the spreading System is more complex due to the existence of a possible triple junction located around 15° S. The eastern part of the N-Fiji basin, west of Viti Levu is mostly characterized by alternating highs and deeps (&lt;4,000 m). This area must be regarded no more as a spreading center, but as complex boundary suffering transverse tectonics.

During Leg 66 eight sites were drilled to form a transect across the Middle America Trench off southwestern Mexico. Cores from these sites show that accretion began approximately 10 MY ago and has continued to the present. Accretion began with offscraping followed by a 2- to 4- MY episode of folding and faulting with uplift rates of 400-500 m/MY; uplift then slowed to 100-200 m/MY, and seismically resolved deformation ceased as the wedge appeared to rise evenly. Approximately 33% of the sediment flux input into the subduction zone, mainly trench sand and slump deposits, is scraped off and incorporated into the toe of the lower slope; an additional 33% is initially subducted but then peeled off to underplate the accretionary wedge; the remaining 33% is...

Des séries d'amendements ont été effectuées, en période estivale, dans des claires de grand volume (600 à 800 m3) et dans une réserve d'eau de 16 000 à 30 000 m3 alimentant la nurserie de la SATMAR, située à Marennes - Oléron, afin d'augmenter la production phytoplanctonique. Les essais en claires permettent de révéler : -le rôle de l'azote comme premier facteur limitant : seul un ajout d'azote (entre 10 et 60 µg.at.l-1 ) implique un développement rapide mais bref des populations algales in situ. Les teneurs en chlorophylle a obtenues ne dépassent pas 43 µG.l-1.  - l'importance du CO2 qui peut être le second facteur limitant avant le phosphore ou la silice ; ces deux derniers éléments semblent plus jouer un rôle au niveau de la vitesse ou de la qualité des...

Accumulation and depuration of hydrocarbons in the mangrove oyster Crassostrea rhizophorae
Provedor de dados: 5
Autores: Delcastillo, C; Corredor, J; Morell, J.
Adult specimens of Crassostrea rhizophorae were exposed to diesel oil dispersed in seawater. The experiment consisted of a 10 days contamination period and 15 days depuration period. Oyster samples were extracted, and analysed by gas chromatography and UV fluorescence spectroscopy. The concentrations of n-alkanes, branched alkanes, unresolved complex mixture (UCM) and aromatic hydrocarbons were determined. The oysters accumulated the hydrocarbons rapidly, reaching a maximum concentration of 387.5 ug/g (wet weight). After exposure to uncontaminated seawater, the oysters were able to reduce their hydrocarbon load to 5.6 ug/g. The data indicates that C. rhizophorae is capable of preferential accumulation and depuration of hydrocarbons. Apparently, the oysters...

Accumulation and dispersion dynamics of mud and sand particles in a continental shelf under estuarine influence: a numerical modelling analysis (Gironde, France)

Autores: Diaz, Melanie; Grasso, Florent; Le Hir, Pierre; Caillaud, Matthieu; Thouvenin, Benedicte.
Coastal environments are directly influenced by terrigenous inputs coming from rivers through estuaries. Quantifying the amount of nutrients and contaminants brought by sediments from continental areas to the sea is of major interest for marine resource protection. The complexity of the intra-estuarine dynamics, associated with the strong variability of meteorological forcing makes it difficult to quantify the residence time of particles within the estuary and the accumulation and dispersion areas offshore the mouth. Moreover, the dynamics of fine sediment trapping areas in the adjacent continental shelf (e.g. temporary or permanent storage such as the “West-Gironde Mud Patch” (WGMP) ) remains extremely challenging to address. Based on a realistic...

Accumulation and fragmentation of plastic debris in global environments
Provedor de dados: 5
Autores: Barnes, David K. A.; Galgani, Francois; Thompson, Richard C.; Barlaz, Morton.
One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines of even the most remote islands and in the deep sea. Annual clean-up operations, costing millions of pounds sterling, are now organized in many countries and on every continent. Here we document global plastics production and the accumulation of plastic waste. While plastics typically constitute approximately 10 per cent of discarded waste, they represent a much greater proportion of the debris accumulating on shorelines. Mega- and...

Total lipid content and lipid class composition were analyzed in gonads, liver and white muscle of yellowfin tuna (Thunnus albacares) throughout ovary development to understand its reproductive allocation strategy and to assess the relation between female condition and reproduction. A total of 112 females were collected onboard purse-seiner in the Western Indian Ocean from January to March 2009, from June to July 2009, and from April to May 2010. Gonads were characterized by highly variable total lipid contents ranging from 5 to 27 μg mg−1 of wet weight (ww) with a predominance of neutral lipids, mainly triacylglycerols (TAG) and sterol- and wax-esters. The different lipid classes in gonads described an accumulative pattern through the maturity process...

Autores: Juhel, Jean-baptiste; Utama, Rizkie S.; Marques, Virginie; Vimono, Indra B.; Sugeha, Hagi Yulia; Kadarusman,; Pouyaud, Laurent; Dejean, Tony; Mouillot, David; Hocdé, Régis.
Environmental DNA (eDNA) has the potential to provide more comprehensive biodiversity assessments, particularly for vertebrates in species-rich regions. However, this method requires the completeness of a reference database (i.e. a list of DNA sequences attached to each species), which is not currently achieved for many taxa and ecosystems. As an alternative, a range of operational taxonomic units (OTUs) can be extracted from eDNA metabarcoding. However, the extent to which the diversity of OTUs provided by a limited eDNA sampling effort can predict regional species diversity is unknown. Here, by modelling OTU accumulation curves of eDNA seawater samples across the Coral Triangle, we obtained an asymptote reaching 1531 fish OTUs, while 1611 fish species...

During ovogenesis the ovary of Carcinus maenas shows a continuous accumulation of Fe, Cu, Mg, Mn and Co. For Zn the accumulation seems to stop for gonad indexes near 6.5. The goal of this accumulation is not determined. Nevertheless we suppose that it is in relation with the role of organic reserves that possess the female sexual cells in decapods and with the synthesis of enzymes and hemocyanin.

Kelps are dominant primary producers in temperate coastal ecosystems. Large amounts of kelp biomass can be exported to the seafloor during the algal growth cycle or following storms, creating new ecological niches for the associated microbiota. Here, we investigated the bacterial community associated with the kelp Laminaria hyperborea during its accumulation and degradation on the seafloor. Kelp tissue, seawater and sediment were sampled during a six‐month in situ experiment simulating kelp detritus accumulation. Evaluation of the epiphytic bacterial community abundance, structure, taxonomic composition and predicted functional profiles evidenced a biphasic succession. Initially dominant genera (Hellea, Litorimonas, Granulosicoccus) showed a rapid and...

Provedor de dados: 5
Autores: Mauriac, R.; Moutin, T.; Baklouti, M.
The biogeochemistry of carbon and nutrients (N,P) in the surface layer of the ocean strongly depends on the complex interactions between primary producers (phytoplankton) and remineralizers (heterotrophic bacteria). To understand how these interactions impact the overall DOC dynamics in the surface layer of the Mediterranean Sea, we implemented, using Eco3M (Ecological Mechanistic Modular Modelling tool), a multi-element model with a mechanistic description of primary production. We studied the model steady state results under various nutrient conditions and fixed cell abundances. By doing so, we show how the bottom up control of osmotrophs growth can impact the overall DOC dynamics in the system. Based on our set of parameters, the biogeochemical...

Accumulation of Fe oxyhydroxides in the Peruvian oxygen deficient zone implies non-oxygen dependent Fe oxidation
Provedor de dados: 5
Autores: Heller, Maija Iris; Lam, Phoebe J.; Moffett, James W.; Till, Claire P.; Lee, Jong-mi; Toner, Brandy M.; Marcus, Matthew A.
Oxygen minimum zones (OMZs) have been proposed to be an important source of dissolved iron (Fe) into the interior ocean. However, previous studies in OMZs have shown a sharp decrease in total dissolved Fe (dFe) and/or dissolved Fe(II) (dFe(II)) concentrations at the shelf-break, despite constant temperature, salinity and continued lack of oxygen across the shelf-break. The loss of both total dFe and dFe(II) suggests a conversion of the dFe to particulate form, but studies that have coupled the reduction-oxidation (redox) speciation of both dissolved and particulate phases have not previously been done. Here we have measured the redox speciation and concentrations of both dissolved and particulate forms of Fe in samples collected during the U.S. GEOTRACES...

Autores: Metian, M.; Bustamante, Paco; Hedouin, L.; Warnau, M.
Uptake of waterborne Cd, Co, Mn and Zn was determined in laboratory experiments using radiotracer techniques (Cd-109, Co-57, Mn-54 and Zn-65). Labelled Zn was mainly accumulated in the digestive gland (65%) and Co in kidneys (81%); Cd and Mn were similarly distributed in digestive gland and gills. In a complementary field study, Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, and Zn were analysed in scallops collected at two stations showing different contamination levels. Digestive gland and kidneys displayed the highest concentrations. Ag, As, Cd, and Fe differed in soft tissues from the two stations, suggesting that Comptopallium radula could be a valuable local biomonitor species for these elements. Low Mn and Zn concentrations found in kidneys suggest that their...

This study demonstrates the long-term stability of salinity measurements from Argo floats equipped with inductive conductivity cells, which have extended float lifetimes as compared to electrode-type cells. New Argo float sensor payloads must meet the demands of the Argo governance committees before they are implemented globally. Currently, the use of CTDs with inductive cells designed and manufactured by RBR Ltd., has been approved as a Global Argo Pilot. One requirement for new sensors is to demonstrate stable measurements over the lifetime of a float. To demonstrate this, data from four Argo floats in the western Pacific Ocean equipped with the RBRargo CTD sensor package are analyzed using the same Owens-Wong-Cabanes (OWC) method and reference datasets...

To monitor coastal environments, Unmanned Aerial Vehicle (UAV) is a low-cost and easy to use solution to enable data acquisition with high temporal frequency and spatial resolution. Compared to Light Detection And Ranging (LiDAR) or Terrestrial Laser Scanning (TLS), this solution produces Digital Surface Model (DSM) with a similar accuracy. To evaluate the DSM accuracy on a coastal environment, a campaign was carried out with a flying wing (eBee) combined with a digital camera. Using the Photoscan software and the photogrammetry process (Structure From Motion algorithm), a DSM and an orthomosaic were produced. Compared to GNSS surveys, the DSM accuracy is estimated. Two parameters are tested: the influence of the methodology (number and distribution of...

We present accuracy assessments for several global ( CSR4, FES2004, FES99, GOT00.2, NAO. 99b, TPXO6.2) and Antarctic (CADA00.10 and CATS02.01) ocean tide models using coastal and pelagic tide gauges, gravimetric data and GPS records of ice shelf surface elevation. The accuracies of CSR4 and NAO. 99b are poor in the ice shelf regions. The optimum model for the entire circum-Antarctic seas is TPXO6.2, with a root-mean-square deviation of similar to 5 - 7 cm, similar to 40% lower than the next best model, FES2004. The main exception is the Filchner-Ronne Ice Shelf...

Accuracy of BLUP breeding values in a factorial mating design with mixed families and marker-based parentage assignment in rainbow trout Oncorhynchus mykiss
Provedor de dados: 5

Marker-based parentage assignment provides the opportunity to investigate factors of efficiency for mixed-family designs and factorial mating. In such designs, family size is both uncontrolled and small, which may be thought to limit the accuracy of estimated breeding values (EBVs). The objective of this work was to estimate the accuracy of EBVs of growth and quality traits in a large factorial mating design and in commercial breeding conditions. An expected six hundred full-sib families of rainbow trout Oncorhynchus mykiss (2042 fish in total) were produced by ten factorial matings of six dams with ten sires. Fish were phenotyped for body weight, carcass yield, fillet yield, fillet fat content and fillet colour, and family information was recovered using...

Accuracy of Wind Measurements Performed on Buoys, Ship, and Island during the TOSCANE-2 Experiment
Provedor de dados: 5
Autores: Queffeulou, Pierre.
In 1983 the project "Travaux d'Oceanographie Spatiale: Capteurs Actifs dans l'Atlantique Nord-Est" (TOSCANE) was initiated in view of calibration, validation, and use of satelliteborne scatterometer and altimeter measurements in terms of wind and wave data, with special emphasis on the ERS-1 satellite to be launched in 1991 by the European Space Agency. The wind measurements from an array of buoys and ship and land stations, deployed during the last experiment within the program, TOSCANE-2, are described, and a method is given to evaluate their accuracy. When comparing wind data from two measuring stations at sea, the averaging time has to be selected according to the separation distance between the two locations to filter out the space-induced wind...

A novel anaerobic bacterial strain, ST07-YET, was isolated from a carbonate chimney of the Prony Hydrothermal Field (PHF) in New Caledonia. Cells were Gram-stain-positive, straight rods (0.7-0.8 x 3.0-5.0 mu m) and motile by means of lateral flagella. Strain ST07-YET was mesophilic (optimum 35 degrees C), moderately alkaliphilic and halotolerant (optimum pH 8.7 and 5 gr l(-1) NaCl). Elemental sulfur, sulfate, thiosulfate, sulfite, nitrate and nitrite were not used as terminal electron acceptors. Yeast extract, peptone, tryptone, Casamino acids, crotonate, pyruvate, galactose, maltose, sucrose, ribose, trehalose and glucose were used as carbon sources. Glucose fermentation led to acetate, H-2 and CO2 formation. Arginine, serine, histidine, lysine,...

Acetylcholinesterase activity in copepods (Tigriopus brevicornis) from the Vilaine River estuary, France, as a biomarker of neurotoxic contaminants
Provedor de dados: 5
Autores: Forget, Joelle; Beliaeff, Benoit; Bocquene, Gilles.
From April 1997 to June 1998, 14 measurements of acetylcholinesterase (AChE) enzymatic activity were performed with the copepod, Tigriopus brevicornis, collected at five stations in the Vilaine River estuary (South Brittany, France). Simultaneously, four chemical analyses of triazines and one analysis of total pesticides in water were undertaken. AChE activity levels in T brevicornis were compared to the levels measured at a reference site not exposed to effluents from Vilaine River. Results reveal significant differences between AChE activity levels depending on location of stations in the plume of the river with an increasing gradient of activity from the upstream to the downstream stations, thus indicating that neurotoxic contaminants are mainly brought...

Achieving single species maximum sustainable yield (MSY) in complex and dynamic fisheries targeting multiple species (mixed fisheries) is challenging because achieving the objective for one species may mean missing the objective for another. The North Sea mixed fisheries are a representative example of an issue that is generic across most demersal fisheries worldwide, with the diversity of species and fisheries inducing numerous biological and technical interactions. Building on a rich knowledge base for the understanding and quantification of these interactions, new approaches have emerged. Recent paths towards operationalizing MSY at the regional scale have suggested the expansion of the concept into a desirable area of “pretty good yield”, implemented...

An integrated understanding of both social and ecological aspects of environmental issues is essential to address pressing sustainability challenges. An integrated social-ecological systems perspective is purported to provide a better understanding of the complex relationships between humans and nature. Despite a threefold increase in the amount of social-ecological research published between 2010 and 2015, it is unclear whether these approaches have been truly integrative. We conducted a systematic literature review to investigate the conceptual, methodological, disciplinary, and functional aspects of social-ecological integration. In general, we found that overall integration is still lacking in social-ecological research. Some social variables deemed...

Acid digestion on river influenced shelf sediment organic matter: Carbon and Nitrogen contents and isotopic ratios
Provedor de dados: 5
Autores: Pasquier, Virgil; Sansjofre, Pierre; Lebeau, Oanez; Liorzou, Celine; Rabineau, Marina.
Rationale Natural stable isotopes ratios (d13Corg and 15N vales) and associated elemental concentrations (i.e. total organic carbon and total nitrogen contents) preserved in marine sediments are frequently used for the determination of paleoenvironmental processes such as the origin of organic matter. Previous studies highlighted biases in the determination of such geochemical proxies due to pre-analysis acid treatment methods. This study is the first systematic comparison of the effect of acid treatment methods on bulk organic matter using a unique sedimentary system, under two contrasting climatic contexts (i.e. glacial vs interglacial). Methods We used the most common method for pre-treatment analysis, which consists of the acidification of bulk...

The existence of deep-sea hydrothermal thermophilic archaebacteria raises interesting questions about their metabolism and metabolic products both in a natural environment and in a culture medium. Moreover, the use of these microorganisms as a potential source of molecules of biotechnological interest must be considered, in the light of the fact that metabolic produits can enhance the risk of microbially-induced corrosion. Organic acids formed by an anaerobic thermophilic sulphur-dependent archaebacterium were analysed as tert-butyldimethylsilyl derivatives by GC and GC/MS. Data indicated the presence in significant amounts of propanoic, 2-methyl propanoic, 3-(methylthio) propanoic, phenylacetic and 4-hydroxyphenylacetic acids. In addition, the use of...

Acoustic accelerometry reveals diel activity patterns in premigratory Port Jackson sharks
Provedor de dados: 5
Autores: Kadar, Julianna; Ladds, Monique; Mourier, Johann; Day, Joanna; Brown, Culum.
Distinguishing the factors that influence activity within a species advances understanding of their behavior and ecology. Continuous observation in the marine environment is not feasible but biotelemetry devices provide an opportunity for detailed analysis of movements and activity patterns. This study investigated the detail that calibration of accelerometers measuring root mean square (RMS) acceleration with video footage can add to understanding the activity patterns of male and female Port Jackson sharks (Heterodontus portusjacksoni) in a captive environment. Linear regression was used to relate RMS acceleration output to time‐matched behavior captured on video to quantify diel activity patterns. To validate captive data, diel patterns from captive...

An Acoustic Doppler Current Profiler (ADCP) was moored at the deep-sea site of the ANTARES neutrino telescope near Toulon, France, thus providing a unique opportunity to compare high-resolution acoustic and optical observations between 70 and 170 m above the sea bed at 2475 m. The ADCP measured downward vertical currents of magnitudes up to 0.03 m s(-1) in late winter and early spring 2006. In the same period, observations were made of enhanced levels of acoustic reflection, interpreted as suspended particles including zooplankton, by a factor of about 10 and of horizontal currents reaching 0.35 m s(-1). These observations coincided with high light levels detected by the telescope, interpreted as increased bioluminescence. During winter 2006 deep...

Autores: Sahin, Cihan; Verney, Romaric; Sheremet, Alexandru; Voulgaris, George.
Observations of suspended sediment size and concentration, flow and acoustic backscatter intensity collected on the Seine Estuary (France) are used to study the acoustic response in cohesive-sediment dominated environments. Estimates of suspended sediment concentration based on optical backscatter sensors and water samples are used to calibrate the acoustic backscatter intensity. The vertical structure of suspended sediment concentration is then estimated from acoustic backscatter information. To our knowledge, this is the first field application of the recently proposed model of acoustic scattering by flocculating suspensions based on the variation of particle density (floc-scattering model). The estimates of sediment concentration reproduce well the...

Acoustic backscattering from salp and target strength estimation
Provedor de dados: 5
Autores: David, P; Guerin-ancey, O; Oudot, G; Van Cuyck, Jp.
Although zooplanktonic organisms nearly have the acoustical impedance of water, they backscatter the sound. Strong acoustical echoes from salps were recorded in the Weddell sea at 150 kHz (1992), in the Indian ocean at 12 kHz (1994) and in the Mediterranean at 120 and 38 kHz (1996). Sphere and cylinder models were applied to estimate the salp target strength. The salp is modelled by a cylindrical gelatinous body (length L) and a spherical nucleus (radius a). Backscattering from each part was estimated individually. With a detection threshold of -100 dB, the minimum body length and the minimum radius of nucleus to be theoretically detected were estimated for each of the following frequencies: 12, 38, 120 and 150 kHz. A small salp (L = 14 rum and a = I mm)...

Autores: De Ruiter, Stacy; Bahr, Alexander; Blanchet, Marie-anne; Hansen, Sabina Fobian; Kristensen, Jakob Hojer; Madsen, Peter T.; Tyack, Peter L.; Wahlberg, Magnus.
Porpoise echolocation has been studied previously, mainly in target detection experiments using stationed animals and steel sphere targets, but little is known about the acoustic behaviour of free-swimming porpoises echolocating for prey. Here, we used small onboard sound and orientation recording tags to study the echolocation behaviour of free-swimming trained porpoises as they caught dead, freely drifting fish. We analysed porpoise echolocation behaviour leading up to and following prey capture events, including variability in echolocation in response to vision restriction, prey species, and individual porpoise tested. The porpoises produced echolocation clicks as they searched for the fish, followed by fast-repetition-rate clicks (echolocation buzzes)...

Acoustic behaviour of male European lobsters (     Homarus gammarus     ) during agonistic encounters
Provedor de dados: 5
Autores: Jézéquel, Youenn; Coston-guarini, Jennifer; Chauvaud, Laurent; Bonnel, Julien.
Previous studies have demonstrated that male European lobsters (Homarus gammarus) use chemical and visual signals as a means of intraspecific communication during agonistic encounters. In this study, we show that they also produce buzzing sounds during these encounters. This result was missed in earlier studies because low-frequency buzzing sounds are highly attenuated in tanks, and are thus difficult to detect with hydrophones. To address this issue, we designed a behavioural tank experiment using hydrophones, with accelerometers placed on the lobsters to directly detect their carapace vibrations (i.e. the sources of the buzzing sounds). While we found that both dominant and submissive individuals produced carapace vibrations during every agonistic...

Although many studies have investigated the benthic environment of temperate marine waters, little is known about the acoustic behaviour of the organisms in these habitats, particularly crustaceans. This study focused on the acoustic behaviour of large crustaceans in NE Atlantic coastal regions. A total of 11 crustacean species were recorded in tank-based experiments to identify sound-producing species and the behaviours associated with their sounds as well as to quantitatively characterise and compare the sounds. A total of 34 sounds were associated with behaviours such as moving, feeding, mandible rubbing, swimming, species-specific behaviour and other unidentified behaviours. The sounds included single pulse and pulse train signals that were distributed...

Autores: Doray, Mathieu; Josse, Erwan; Gervain, Paul; Reynal, Lionel; Chantrel, Josselin.
Sea cruises were conducted for 57 days over 16 months to characterise pelagic fish aggregations around 2 moored fish aggregating devices (FADs) in Martinique (Lesser Antilles). Echosounder surveys run in a star pattern were used in conjunction with obliquely beamed sonar observations. An echo-integration-by-shoal algorithm was implemented to isolate pelagic fish shoals from sound scattering layers and to compute mean morphometric, positional and density parameters. Tree regressions were used to select and classify pelagic fish Target Strengths (TS), with reference to their spatial and temporal characteristics. The main type of pelagic fish aggregation was a large sub-surface aggregation. It was observed during all daytime periods within a radius of 400 m...

Acoustic data collected during and between bottom trawl stations: consistency and common trends
Provedor de dados: 5
Autores: Bez, Nicolas; Reid, David; Neville, Suzanna; Verin, Yves; Hjellvik, Vidar; Gerritsen, Hans D.
Acoustic data are often collected during bottom trawl surveys. Their use can potentially improve the precision and accuracy of fish abundance estimates if acoustic data collected between trawl stations are consistent with those collected during trawling operations. This question is addressed here through the analysis of 20 bottom trawl surveys (three survey areas and five different survey series) with coincident acoustic measurements during and between trawl stations. Firstly, on-station and underway acoustic data were compared using statistics computed globally over each survey (average vertical profiles, global indices of collocations, and spatial structures) for various combinations of depth layers. Secondly, we focussed on underway acoustic data...

Echo sounder data were used to investigate the spatio-temporal variability of shoal behaviour in the Bay of Biscay. Data collected from annual surveys were processed using MOVIES-B software in order to mcasure this variability. The software was designed to measure morphological, energetic and space-time distribution descriptors from the acoustic signal received from fish shoals. Two surveys, DAAG 90 and DAAG 91, provided the appropriate characteristics for such an analysis. The survey's objective was to obtain relative abundance indices for the anchovy (Engraulis encrasicolus) biomass in the Bay of Biscay. The surveys were carried out in the same area (southern Bay of Biscay), at the same period (April) within one year interval (1990 and 1991), using the...

Acoustic monitoring of gas emissions from the seafloor. Part I: quantifying the volumetric flow of bubbles
Provedor de dados: 5
Autores: Leblond, Isabelle; Scalabrin, Carla; Berger, Laurent.
Three decades of continuous ocean exploration have led us to identify subsurface fluid related processes as a key phenomenon in marine earth science research. The number of seep areas located on the seafloor has been constantly increasing with the use of multi-scale imagery techniques. Due to recent advances in transducer technology and computer processing, multibeam echosounders are now commonly used to detect submarine gas seeps escaping from the seafloor into the water column. A growing number of en-route surveys shows that sites of gas emissions escaping from the seafloor are much more numerous than previously thought. Estimating the temporal variability of the gas flow rate and volumes escaping from the seafloor has thus become a challenge of relevant...

Acoustic observations in the Bay of Biscay: Schooling, vertical distribution, species assemblages and behaviour
Provedor de dados: 5
Autores: Masse, Jacques.
Eight acoustic surveys were carried our in the Bay of Biscay, during 1989-94, to study the distribution and abundance of anchovy (Engraulis encrasicolus, L.) in that area. Acoustic data were stored using the INES/MOVIES acquisition and processing system. Species-specific distribution patterns were confirmed through complementary sampling with a mid-water trawl. This paper summarises the combination of technical procedures used for acoustic assessments, and the results of acoustic surveys in the Bay of Biscay that pertain to the dynamics of this stock. Information is presented on the distribution and abundance of anchovy and co-occuring species, and on the movement patterns detected within the pelagic fish community, in relation to environmental conditions....

Acoustic target classification
Provedor de dados: 5
Autores: Korneliussen, Rolf J.
Data are collected from a variety of acoustic systems in many countries to address a range of ecosystem monitoring and stock management objectives. A key step in the analysis of fisheries acoustics data is target classification, i.e. categorizing the backscatter data, ultimately by target species, so that it can be converted into estimates of abundance or biomass. The information needed to classify acoustic targets may be contained within the acoustic measurements, particularly if they are made over a range of frequencies. The SIMFAMI project, financed by the European Union, presented some multifrequency methods for species identification (Fernandes et al., 2006). Readers should also note that there are two other ICES reports on related topics: CRR No. 238...

Acoustic Tomography in the Canary Basin: Meddies and Tides
Provedor de dados: 5
Autores: Dushaw, Brian; Gaillard, Fabienne; Terre, Thierry.
An acoustic propagation experiment over 308-km range conducted in the Canary Basin in 1997–1998 was used to assess the ability of ocean acoustic tomography to measure the flux of Mediterranean water and Meddies. Instruments on a mooring adjacent to the acoustic path measured the southwestward passage of a strong Meddy in temperature, salinity, and current. Over nine months of transmissions, the acoustic arrival pattern was an initial broad stochastic pulse varying in duration by 250 to 500 ms, followed eight stable, identified ray arrivals. Small-scale sound speed fluctuations from Mediterranean water parcels littered around the sound channel axis caused acoustic scattering. Internal waves contributed more modest acoustic scattering. Based on simulations,...

Acoustical monitoring of fish density, behavior, and growth rate in a tank
Provedor de dados: 5
Autores: Conti, Stéphane; Roux, Philippe; Fauvel, Christian; Maurer, Benjamin; Demer, David.
A challenge for the aquaculture community has long been the development of harmless techniques for monitoring fish in a tank. Acoustic telemetry has been used to monitor fish swimming behavior, and passive acoustics have been used to monitor fish feeding, but new techniques are needed to monitor non-invasively their numbers and growth rates. Recently, it has been demonstrated that the acoustical total scattering cross section of fish swimming in a tank can be measured from multiple reverberation time series. These measurements have been used successfully to estimate the number of fish in a tank in laboratory conditions, and to characterize their acoustical signatures. Here, we introduce a novel method for acoustically monitoring fish numerical density and...

Acoustique sous-marine. Présentation et applications
Provedor de dados: 5
Autores: Lurton, Xavier.
Sound waves are the only practical means of remote investigation and transmission in seawater. All along the XXth century, underwater acoustics became one of the major technologies used for exploration and exploitation of the oceans for scientific, industrial, or military purposes. It is nowadays able to play, inside the oceans, the roles devoted to radio and radar in atmosphere and space, and is widely employed in the fields of navigation, fisheries, defence, oceanography and ocean engineering. This book presents, in a clear and concise way, the basic physical phenomena governing underwater acoustical waves, the general features of sonar systems, and an overview of their applications.

Research on the black scallop followed that on the king scallop. Indeed, over the 1973-1975 " spadework » period, it has been demonstrated that the roadsted of Brest was: - an overexploited king scallop deposit; the broodstock not being able to ensure a satisfying renewal of the species. - a black scallop production deposit (hundreds of tonnes). In parallel, the collection trials provided null results for the king scallop but very interesting results for the black scallop (thousands of spats per collector). From 1976 onwards, the spat collecting operations did not focus on king scallop juveniles anymore, but on black scallop.

The continuous obtention of different signals has been achieved for 9 days at a -fixed station during May 1988. The speed and direction of the currents have been monitoring concurrently with "in situ" turbidity and fluorescence in relation with the meteorological conditions. The concentration in particulate matter and the planktonic fluorescence fluctuated in direct relation with the water depth, the speed of the current and with the origin of the water masses. The oysters submitted to these large fluctuated conditions showed not constant filtration rate. The filtration calculated by turbidimeters (2 1 h-l g-1 dry weight) was three time less than the one achieved with fluorimeters (61 h-l g-1 dry weight).

Studies on phytoplankton community diversity cannot be limited microphytoplankton (cells&gt;20 ìm), it is indeed necessary to take into account also the nano (3-20ìm) picophytoplankton (&lt;3 ìm) components. In the frame of this work aimed at studying temporal phytoplankton community diversity two complementary methodologies of phytoplankton sample analysis, pigment and genetic (metarbarcoding) diversity, have been used as alternative to routine morphological analysis carried out at light microscopy. The REPHY station (047-P-016 Concarneau Large) off-shore the Concarneau Bay has been sampled during the annual highest phytoplankton production (March-July 2012) with a frequent sample interval strategy (twice per week). Results obtained by both pigment and...

The European Union Water Framework Directive (WFD) refers to phytoplankton as one of the biological quality elements that should be regularly monitored and evaluated thanks to three ecological indices: biomass, abundance and composition. The first two have already been defined, but the third one has not yet been proposed in the English Channel-Atlantic zone. The construction of a composition indice must consider the diversity of all the phytoplankton. As the microscopic counts concern only the micro-phytoplankton, it is necessary to use additional information which concerns the nano- and pico-phytoplankton, of great importance when estimating the phytoplankton diversity. These components of the phytoplankton can be measured by different complementary...

Acquisition of detrital magnetization in four turbidites
Provedor de dados: 5
Autores: Tanty, Cyrielle; Valet, Jean-pierre; Carlut, Julie; Bassinot, Franck; Zaragosi, Sebastien.
Turbiditic events are mostly avoided in paleomagnetic studies and therefore their remanence and magnetic properties are poorly described. Turbidites are exempt of bioturbation and potentially provide pertinent information about depositional remanence. We studied four quaternary turbidites of different origins in marine sediment cores. Upward fining of both magnetic and sedimentary fractions indicates that coarser grains reached the bottom first. We observe a progressive shallowing of the magnetic inclinations between the upper and bottom layers of the turbidites that increases with the size of the events and obeys a simple linear scaling law. Measurements of magnetic anisotropy suggest that hydrodynamic conditions prevailing during deposition seem to be...

Autores: Guri, Mathieu; Durand, Lucile; Cueff-gauchard, Valerie; Zbinden, Magali; Crassous, Philippe; Shillito, Bruce; Cambon-bonavita, Marie-anne.
The caridean shrimp Rimicaris exoculata dominates the fauna at several Mid-Atlantic Ridge hydrothermal vent sites. This shrimp has an enlarged gill chamber, harboring a dense ectosymbiotic community of chemoautotrophic bacteria associated with mineral oxide deposits. Until now, their acquisition is not fully understood. At three hydrothermal vent sites, we analyzed the epibionts diversity at different moult stages and also in the first stages of the shrimp life (eggs, hatched eggs (with larvae) and juveniles). Hatched eggs associated with young larvae were collected for the first time directly from gravid females at the Logachev vent site during the Serpentine cruise. An approach using 16S rRNA clone libraries, scanning and transmission electron...

Acquisition of susceptibility to Vibrio penaeicida in Penaeus stylirostris postlarvae and juveniles
Provedor de dados: 5
Autores: Goarant, Cyrille; Regnier, France; Brizard, Raphael; Marteau, Anne-laure.
Vibriosis is a major disease problem in shrimp aquaculture, affecting all developmental stages, from larvae in hatchery tanks to juveniles and broodstock in growout ponds. However, bacterial strains responsible for vibriosis in the successive stages are usually considered to be different, and virulence specificity has been reported both at the species and at the stage levels. The so-called « Syndrome 93 » is a seasonal juvenile vibriosis caused by Vibrio penaeicida which affects Penaeus stylirostris in growout ponds and broodstock tanks in New Caledonia. This pathology does not cause any mortality in hatchery or nursery phases. An experimental infection design using balneation of postlarvae and early juveniles in V. penaeicida suspensions was used to...

Acquisition of the neodymium isotopic composition of the North Atlantic Deep Water
Provedor de dados: 5
Autores: Lacan, F; Jeandel, C.
The North Atlantic Deep Water (NADW) neodymium isotopic composition (Nd IC) is increasingly used in oceanography and paleoceanography to trace large-scale circulation and weathering processes, notably to investigate past variations of the global thermohaline circulation. Although the present-day NADW Nd IC is well characterized at epsilon(Nd) = - 13.5, the acquisition of this isotopic signature ( in other words, the causes of this value) has so far been very sparsely documented. Such an understanding is, however, fundamental to the interpretation of paleo records. Nd IC and rare earth element concentrations were measured at 9 stations within the North Atlantic Subpolar Gyre ( SIGNATURE cruise, summer 1999). The comparison of this data set with our...

Autores: Doumenc, D; Van-praet, M.
The Biocyatherm 1 expedition permitted observation of six species of Hexactiniaria, four of which were collected. Three species collected towards the edge of the site, on its basaltic floor, in areas without thermal anomaly, belong to common deep-sea genera (Phelliactis, Chondrophellia, Actinostola ). The sea anemone collected from the active vents belongs to a new genera of the family Actinostolidae. A few Cyananthea hydrothermala were observed on both chimneys. Ultrastructural investigation of this sea anemone reveals a few bacteria in the phagocytic cells of digestive tissues. Their location and the presence of hydrolases suggest that bacteria form part of the diet of sea anemones and are not symbiotic.

Autores: Weyland, H.
Occurrence, distribution and physiological characteristics of actinomycetes in the top of the sediments of various seas were studied. Viable counts were very low in open sea sites. The majority of the isolates could be grouped to streptomycetes, Micromonosporae and nocardioforms. Streptomycetes are preponderantly distributed in coastal and shelf regions. They exhibit relatively broad temp. and salinity spectra and allow baroresistance. Micromonosporae are found in relation to the other taxa more frequently in deep sea sediments. They grow better in media with low salt concentration and have a temp. optimum around 30 degree C.

Faced with the decline of scallop {Pecten maximus) fisheries and high costs of ongrowing in suspension, scallop seabed cultivation appeared to be the most suitable technique for European conditions. A three-year European Concerted Action supported by European Union and Norway (associated country) joined together four teams involved in scallop seedings : - IFREMER Brest / laboratory Molluscs, in Brittany (France), a national institute of ocean research (co-ordinator of the Concerted Action) ; - Connemara Shellfish Co-op, in Connemara, County of Galway (Ireland), a fishermen's co-operative ; - Seafish Ardtoe, in Scotland (United Kingdom), an institute provided by the fishing industry ; - Institute of Marine Research, in Bergen (Norway), a national institute...

Action de la houle sur les sédiments
Provedor de dados: 5
Autores: Leclerc, J.p.; Bellessort, B.; Migniot, C.
Sous l'action de la houle les sédiments peuvent être soumis à différents mouvements se traduisant par de simples oscillations sur place, des déplacements dans le profil perpendiculairement à la côte ou un transit littoral dont la direction et l'importance dépendront essentiellement des caractéristiques de la houle, des matériaux et du profil des fonds. La nombreuse documentation disponible sur ce sujet pourrait faire penser que ces problèmes sont bien connus et qu'il suffit d'appliquer un certain nombre de formules existant dans la littérature pour avoir une réponse précise sur le comportement des galets, graviers, sables ou vases répartis à différentes profondeurs du pré-continent.

The Tributyl tin acetate, a component of certain antifouling paints, has deleterious effects on eggs and D shaped larvae from Crassostrea gigas at 5 p.p.b. (HIS &amp; ROBERT, 1980). Here we have tested concentrations as low as 1 p.p.b. on eggs and on 24 hours old larvae both from Crassostrea gigas and Mytilus galloprovincialis. The same results are got ; this product kills embryos and larvae in a few days ; it prevents growth of 24 hours old larvae exposed to this toxic. Mussels larvae seem to be less sensitive.

Autores: Robert, Rene; Nicolas, Jean-louis; Conan, Rony.
For lack of antibiotics, King scallop larviculture faces high mortalities. In the experimental mollusc hatchery of Argenton (Brittany, France), the presence of a vibrio, Vibrio pectinicida, associated with the stocks seems to be responsible for this low survival rate. As prophylactic methods are difficult to implement in the current structures (water sterilization, egg decontamination, isolation of the stocks), the addition of chloramphenicol is the only solution to protect the stocks. However, the use of this antibiotic, considered as dangerous for man, has been prohibited in animal production throughout the whole of Europe since 1994. The action of two other antibiotics, the erythromycine and the oxolinic acid, has been searched for in Pecten maximus...

Le centre de recherches Antilles-Guyane a été crée en début d'année dans le but de coordonner les activités du laboratoire de Cayenne et celles du laboratoire du Robert, ce dernier couvrant la Martinique et la Guadeloupe. Cette coordination peut surprendre si l'on considédère que la Guyane et les Antilles représentent pour l'océanographie des pêches des terrains de recherche très opposés, l'un étant caractérisé par un large plateau sous-marin soumis à une forte influence des eaux continentales, l'autre par un milieu insulaire, accore, situé dans les grands fonds. Mais, du point de vue de l'économie des pêches, cette opposition fait, au contraire, que ces deux régions géographiques relativement proches devraient être complémentaires.

Autores: Hernandorena, A.
Heat shocks at 40 degree were delivered to Artemia at the end of embryonic development and at the beginning of postembryonic development and their effects on subsequent development examined. Heat shocks delivered during preemergence development have no effect on subsequent development. Heat shocks delivered to newly hatched nauplii induce anomalies on the morphogenesis of thoracic and genital appendages. The induction of morphological anomalies by thermal conditions prevailing during early larval life makes it easier to integrate the morphological effects previously induced by nutritional conditions imposed to older feeding stages.

Action des facteurs hydrologiques et sédimentaires sur le budget énergétique de la palourde japonaise Ruditapes philippiarum élevée dans un écosystème estuarien (Bassin de Marennes-Oléron, France)
Provedor de dados: 5
Autores: Daou, Rafik.
Afin d'étudier l'action du sédiment sur les populations de Ruditapes philippinarum, 12 000 individus ont été répartis en 1986 sur 3 substrats dans le bassin de Marennes-Oléron. Tous les paramètres du milieu sont analysés sur les 3 sites pendant un cycle annuel parallèlement aux suivis biométriques, biochimiques et énergétiques sur les animaux. Ainsi dans ce secteur d'élevage "Les Doux" où l'influence estuarienne (Charente) est faible, les phénomènes circadiens, régissant la dynamique sédimentaire, n'affectent pas la distribution du matériel dissous. L'étude des différents fractions sestoniques au dessus de chaque parc montre qu'ils sont recouverts par la m^me masse d'eau.  Par ailleurs, les effets négatifs des sédiments à fortes teneurs pélitiques sur les...

Autores: Mieszkin, Sophie; Hymery, Nolwenn; Debaets, Stella; Coton, Emmanuel; Le Blay, Gwenaelle; Valence, Florence; Mounier, Jerome.
The use of lactic acid bacteria (LAB) as bioprotective cultures can be an alternative to chemical preservatives or antibiotic to prevent fungal spoilage in dairy products. Among antifungal LAB, Lactobacillus harbinensis K.V9.3.1Np showed a remarkable antifungal activity for the bioprotection of fermented milk without modifying their organoleptic properties (Delavenne et al., 2015). The aim of the present study was to elucidate the action mechanism of this bioprotective strain against the spoilage yeast Yarrowia lipolytica. To do so, yeast viability, membrane potential, intracellular pH (pHi) and reactive oxygen species (ROS) production were assessed using flow cytometry analyses after 3, 6 and 10 days incubation in cell-free supernatants. The tested...

Many social-ecological system(SES)-based approaches have been proposed to address environmental problems. Most social-ecological frameworks developed to date, however, lack clear operational linkages between humans and nature to efficiently guide SESs toward resilience. A conceptual framework designed to be operational is therefore necessary, as well as a network of research platforms with which to apply it. We defined explicit coupling processes that can be used as leverages to pilot an SES toward sustainability. We proposed to formalize an SES as a dynamic entity composed of two coupling interfaces, i.e., adaptive management and ecosystem services, both set within a landscape context to provide an actionable framework. These interfaces describe the way...

Kisspeptins are well known as mediators of the coordinated communication between the brain-pituitary axis and the gonads in many vertebrates. To test the hypothesis that gonadal steroids regulate kiss1 and kiss2 mRNA expression in European sea bass (a teleost fish), we examined the brains of gonad-intact (control) and castrated animals, as well as castrated males (GDX) and ovariectomized females (OVX) that received testosterone (T) and estradiol (E2) replacement, respectively, during recrudescence. In GDX males, low expression of kiss1 mRNA is observed by in situ hybridization in the caudal hypothalamus (CH) and the mediobasal hypothalamus (MBH), although hypothalamic changes in kiss1 mRNA levels were not statistically different among the groups, as...

The ponds are a cultivation environment not only for the oyster but also for the rich microscopic flora and fauna which go together with the lamellibranch. The Diatoms are the focus of the oyster farmers as they not only contribute to the molluscs' nutrition but are also susceptible to change the colour of their gills in specific environmental conditions. We carried out in parallel an experimental study on the oyster and on the marine diatoms, and aimed to precise the optimal conditions for these two organisms, in order to know if they are the same for both of them.

Active and passive biomonitoring suggest metabolic adaptation in blue mussels (Mytilus spp.) chronically exposed to a moderate contamination in Brest harbor (France)
Provedor de dados: 5
Autores: Lacroix, Camille; Richard, Gaelle; Seguineau, Catherine; Guyomarch, Julien; Moraga, Dario; Auffret, Michel.
Brest harbor (Bay of Brest, Brittany, France) has a severe past of anthropogenic chemical contamination, but inputs tended to decrease, indicating a reassessment of its ecotoxicological status should be carried out. Here, native and caged mussels (Mytilus spp.) were used in combination to evaluate biological effects of chronic chemical contamination in Brest harbor. Polycyclic aromatic hydrocarbon (PAH) contamination was measured in mussel tissues as a proxy of harbor and urban pollution. Biochemical biomarkers of xenobiotic biotransformation, antioxidant defenses, generation of reducing equivalents, energy metabolism and oxidative damage were studied in both gills and digestive glands of native and caged mussels. In particular, activities of...

An integrated approach using biomarkers and contaminant levels in mussels Mytilus galloprovincialis L was employed to assess chemical contamination in Greek coastal waters within the framework of the MYTIMED program. Biomarkers (metallothioneins, glutathione S-transferase, catalase, acetylcholinesterase and RNA:DNA ratio) have been previously described in mussels caged at 14 sites in coastal areas influenced by different types of anthropogenic activities. This study applied a biomarker index, the Integrated Biomarker Response (IBR) to summarize biomarker responses and relate stress levels to concentrations of organochlorine compounds (PCBs, DDTs), polycyclic aromatic hydrocarbons (PAHs), and metals (Cu, Ni, Fe, Zn) measured in the mussel tissues. The IBR...

Recently acquired high-resolution multichannel seismic profiles together with bathymetric and sub-bottom profiler data from the external part of the Gulf of Cadiz (Iberia-Africa plate boundary) reveal active deformation involving old (Mesozoic) oceanic lithosphere. This area is located 180 km offshore the SW Iberian Peninsula and embraces the prominent NE-SW trending Coral Patch Ridge, and part of the surrounding deep Horseshoe and Seine abyssal plains. E-W trending dextral strike-slip faults showing surface deformation of flower-like structures predominate in the Horseshoe Abyssal Plain, whereas NE-SW trending compressive structures prevail in the Coral Patch Ridge and Seine Hills. Although the Coral Patch Ridge region is characterized by subdued seismic...

Active fault segments along the North Anatolian Fault system in the Sea of Marmara: implication for seismic hazard
Provedor de dados: 5
Autores: Gasperini, Luca; Stucchi, Massimiliano; Cedro, Vincenzo; Meghraoui, Mustapha; Ucarkus, Gulsen; Polonia, Alina.
A new analysis of high-resolution multibeam and seismic reflection data, collected during several oceanographic expeditions starting from 1999, allowed us to compile an updated morphotectonic map of the North Anatolian Fault below the Sea of Marmara. We reconstructed kinematics and geometries of individual fault segments, active at the time scale of 10 ka, an interval which includes several earthquake cycles, taking as stratigraphic marker the base of the latest marine transgression. Given the high deformation rates relative to sediment supply, most active tectonic structures have a morphological expression at the seafloor, even in presence of composite fault geometries and/or overprinting due to mass-wasting or turbidite deposits. In the frame of the...

Active faulting and deep crustal structure of the Eastern Sicily Margin
Provedor de dados: 5
Autores: Dellong, David.
In the Ionian Sea (central Mediterranean) the slow convergence between Africa and Eurasia results in the formation of a narrow subduction zone. The nature of the crust of the subducting plate remains debated and could represent the last remnants of the Neo-Tethys ocean. The origin of the Ionian basin is also under discussion, especially concerning the rifting mechanisms as the Malta Escarpment could represent a remnant of this opening. This subduction retreats toward the south-east (motion occurring since the last 35 Ma) but is confined to the narrow Ionian basin. A major lateral slab tear fault is required to accommodate the slab rollback.This fault is thought to propagate along the eastern Sicily margin but its precise location remains controversial.This...

Active faulting, submarine surface rupture and seismic migration along the Liquiñe‐Ofqui fault system, Patagonian Andes
Provedor de dados: 5
Autores: Villalobos, Angelo; Vargas Easton, Gabriel; Maksymowicz, Andrei; Ruiz, Sergio; Lastras, Galderic; De Pascale, Gregory P.; Agurto‐detzel, Hans.
The intra‐arc Liquiñe‐Ofqui Fault System (LOFS) is an active transpressive fault zone located in the Patagonian Andes of Chile. In 2007, a seismic sequence occurred in the Aysén Fjord region of Chilean Patagonia along the LOFS, with a Mw 6.2 main earthquake that triggered dozens of landslides, some of which induced tsunami waves that caused severe damage and casualties. Through the analysis of high‐resolution seismic reflection and bathymetric data, we identify six submarine faults cutting the late‐Quaternary postglacial sedimentary infill of the fjord. The most conspicuous are the dextral‐normal NE‐SW‐striking Quitralco fault (QF) and the N‐S striking strike‐slip Río Cuervo (RCF) and Punta Cola faults (PCF). Our paleoseismological analysis reveals at...

Active Tectonics in the Hellenic Trench
Provedor de dados: 5
Autores: Le Pichon, X; Huchon, P; Angelier, J; Lyberis, N; Boulin, J; Bureau, D; Cadet, J P; Blanchet, R; Montadert, L; Dercourt, J; Glacon, G; Got, H; Karig, D; Mascle, J; Ricou, Le; Thiebault, F.
Active deformation of the sea-floor of the Hellenic trench has been observed using the Cyana SP-3000 submersible. The strain pattern observed on a scale of a few kilometers is similar to the one deduced from an analysis of Seabeam morphological maps on a scale of tens of kilometers. The overall strain pattern is compatible with subduction of the Mediterranean sea-floor toward the northeast. It is characterized by underthrusting in the Western Ionian branch and left-lateral strike-slip faulting in the Eastern Strabo branch.

Autores: Gutscher, Marc-andre; Kopp, Heidrun; Krastel, Sebastian; Bohrmann, Gerhard; Garlan, Thierry; Zaragosi, Sebastien; Klaucke, Ingo; Wintersteller, Paul; Loubrieu, Benoit; Le Faou, Yann; San Pedro, Laurine; Dominguez, Stephane; Rovere, Marzia; De Lepinay, Bernard Mercier; Ranero, Cesar; Sallares, Valenti.
The detailed morphology and internal structure of the Calabrian accretionary wedge and adjacent Eastern Sicily margin are imaged in unprecedented detail by a combined dataset of multi-beam bathymetry and high-resolution seismic profiles. The bathymetric data represent the results of 6 recent marine geophysical surveys since 2010 as well as a compilation of earlier surveys presented as a 2 arc-sec (60 m) grid. Several distinct morpho-tectonic provinces are identified including: the deeply incised Malta–Hyblean Escarpment, numerous submarine canyons, broad regions of relatively flat seafloor dominated by fields of sediment waves, the gently undulating anticlinal fold-and-thrust belts of the external Calabrian accretionary wedge and the adjacent portion of...

Active thrust faulting offshore Boumerdes, Algeria, and its relations to the 2003 Mw 6.9 earthquake - art. no. L043111
Provedor de dados: 5
Autores: Deverchere, Jacques; Yelles, K; Domzig, Anne; Mercier De Lepinay, B; Bouillin, J.p.; Gaullier, V; Bracene, R; Calais, E; Savoye, Bruno; Kherroubi, A; Le Roy, P; Pauc, H; Dan, Gabriela.
[1] We investigate the active seismogenic fault system in the area of the 2003 Mw 6.9 Boumerdes earthquake, Algeria, from a high-resolution swath bathymetry and seismic survey. A series of 5 main fault-propagation folds similar to20-35 km long leave prominent cumulative escarpments on the steep slope and in the deep basin. Fault activity creates Plio-Quaternary growth strata within uplifted areas such as a rollover basin on the slope and piggyback basins in the deep ocean. Most thrusts turn to fault-propagation folds at the sub-surface and depict ramp-flat trajectories. We find that the two main slip patches of the 2003 Mw 6.9 Boumerdes earthquake are spatially correlated to two segmented cumulative scarps recognized on the slope and at the foot of the...

Active-passive synergy for interpreting ocean L-band emissivity: Results from the CAROLS airborne campaigns
Provedor de dados: 5
Autores: Martin, A. C. H.; Boutin, Jacqueline; Hauser, D.; Dinnat, E. P.
The impact of the ocean surface roughness on the ocean L-band emissivity is investigated using simultaneous airborne measurements from an L-band radiometer (CAROLS) and from a C-band scatterometer (STORM) acquired in the Gulf of Biscay (off-the French Atlantic coasts) in November 2010. Two synergetic approaches are used to investigate the impact of surface roughness on the L-band brightness temperature (Tb). First, wind derived from the scatterometer measurements is used to analyze the roughness contribution to Tb as a function of wind and compare it with the one simulated by SMOS and Aquarius roughness models. Then residuals from this mean relationship are analyzed in terms of mean square slope derived from the STORM instrument. We show improvement of new...

Activité comparée chez les espèces Crassostrea angulata Lmk et Crassostrea gigas Thunberg, en hiver
Provedor de dados: 5
Autores: His, Edouard.
L'espèce Crassostrea gigas a été introduite en 1969 à titre d'essai par de nombreux ostréiculteurs du bassin d'Arcachon. La comparaison des vitesses de croissance de cette nouvelle espèce et de l'huître indigène C. angulata est nettement à l'avantage de l'huître japonaise. Cette dernière atteint la taille marchande dans la plupart des cas dès la première année d''immersion dans la baie alors qu'il faut généralement de deux à trois ans pour obtenir le même résultat avec l'huître portugaise.

The submersible-study of four segments of the East Pacific Rise between 17 degrees and 18 degrees 40'S, where the spreading rate is greater than 150 mm/a, allows us to confirm the variability of the accretion processes. The segment between 17 degrees and 17 degrees 30'S shows an intense present-day magmatic activity. The one between 18 degrees 10' and 18 degrees 22'S shows a mainly tectonic activity. The segment between 18 degrees 22' and 18 degrees 37'S is an intermediate stage with an axial graben in which fresh lavas were emplaced by an extremely young eruption. On all the segments the hydrothermal activity exists ranging from shimmering water up to black smokers, It is associated with different stages of animal colonization.

Autores: Le Borgne-david, A.
The Portuguese oyster (Crassostrea angulata) and the sea-squirt Ciona intestinalis are both filter-feeders and compete for space in the oyster beds. Valve movement in oysters and shortening and elongation in Ciona were recorded on a smoked drum. Oysters showed a slow (3 one half min) spontaneous opening/closing rhythm, which was speeded up by stimulatory (vitamin) substances and increased in amplitude by toxic accumulated waste substances, or sudden change in temperature. Ciona showed a regular contraction rhythm of similar to 1 min and single sharp shortening after a strong light stimulus or a food particle touch stimulus to the oral tentacles. The neural ganglion discharges spikes 3 times faster than in the dark, after light stimulation. Filtration rates...

Autores: Bougrier, Serge; Geairon, Philippe.
A continuous monitoring system to measure the respiration of Crassostrea gigas has been developped. The metabolic function estimated by oxygen consumption has been monitored during periods of 24 h, without food, at a temperature constant of 15°C. Preliminary results showed that the mean percentage of oyster activities was 50 % with a high variability from 0 to 100 %. The number of activity periods per day (24 h) is function of the oysters with variation between 0 and 7.

The regulation of the synthesis of the digestive enzymes of the zooplankton and the brine shrimp (amylase and trypsine activity) has been studied to find some nutrition indexes enabling the description of the zooplankton's nutritive activity in situ. These regulations lead us to tackle three domains of pelagic ecology:- The evaluation of the organisms' nutrive needs and the capacity of the environment to satisfy them.- The monitoring of the pelagic ecosystem- The disturbance of the ecosystems.

Large yellow croaker is an important marine fish species for aquaculture in China. Larval rearing of this species is still based on live prey feeding. The aim of this study was to describe the onset and development of the main digestive enzymes during larval development of this species, in order to obtain essential data for the formulation of a compound diet adapted to larvae. Enzymatic assays were conducted from day I post hatching to day 40 in larvae fed the following live prey sequence: rotifers, Artemia nauplii, copepods, and then frozen copepods. Assays were done on whole larvae until day 19, then on dissected larvae and on purified brush border membranes of intestine. Pancreatic enzymes, amylase, and trypsin, showed high activities from early stages,...

Autores: Duineveld, Gérard; Lavaleye, Marc; Berghuis, Eilke; De Wilde, Peter.
We compared the sediment and its community on the Celtic continental slope (Goban Spur) with those in a branch of the nearby Whittard Canyon in search for evidence of canyon mediated transport of (labile) organic matter. We studied the megabenthos and macrobenthos biomass and taxonomic composition, measured in situ sediment community oxygen consumption and determined sediment concentrations of particulate organic carbon, phytopigments, and nucleic acids. While the sediment community and activity on the canyon fan was similar to that on the abyssal station near Goban Spur, the sediment within the canyon had relatively enhanced sediment community oxygen consumption rates and higher levels of phytopigments. particulate organic carbon and nucleic acids,...

Activity of the turbidite levees of the Celtic-Armorican margin (Bay of Biscay) during the last 30,000 years: Imprints of the last European deglaciation and Heinrich events
Provedor de dados: 5
Autores: Toucanne, Samuel; Zaragosi, S; Bourillet, Jean-francois; Naughton, F; Cremer, M; Eynaud, F; Dennielou, Bernard.
High-resolution sedimentological and micropaleontological studies of several deep-sea cores retrieved from the levees of the Celtic and Armorican turbidite systems (Bay of Biscay - North Atlantic Ocean) allow the detection of the major oscillations of the British-Irish Ice Sheet (BIIS) and 'Fleuve Manche' palaeoriver discharges over the last 30,000 years, which were mainly triggered by climate changes. Between 30 and 20 cal ka, the turbiditic activity on the Celtic-Annorican margin was weak, contrasting with previous stratigraphic models which predicted a substantial increase of sediment supply during low sea-level stands. This low turbidite deposit frequency was most likely the result of a weak activity of the 'Fleuve Manche' palaeoriver and/or of a...

Provedor de dados: 5
Autores: Jadot, Catherine; Donnay, A; Acolas, M; Cornet, Y; Begout, Marie-laure.
Acoustic telemetry was used to record diel movement and habitat utilization of the salema (Sarpa salpa) (Teleostei: Sparidae) during three consecutive summers from 2000 to 2002 in the Calvi and Achiarina bays of Corsica in the Mediterranean Sea. A total of 18 fish was equipped with acoustic transmitters inserted in the body cavity, 13 were tracked in the Bay of Calvi (275 mm +/- 26.9 L-F), and 5 in Achiarina Bay (260 mm +/- 33.6 LF). Two different systems were used to track the fish. The one used in the Bay of Calvi was a manual receiver and a directional hydrophone. The second system, used in Achiarina Bay, was a radioacoustic-positioning (RAP) system that continuously monitored the movements of the fish. Fish positions were put in a geographic...

Actualisation de connaissances du domaine marin en Guyane Française
Provedor de dados: 5
Autores: Lampert, Luis.
Contrairement aux mers adjacentes européennes, la zone maritime de la Guyane Française n’a été que peu étudiée. L’éloignement, la difficulté de mener des études dans une zone à forte turbidité et avec peu de points d’accès à la mer pour des embarcations, ont conduit à une méconnaissance chronique des cycles biogéochimiques et biologiques dans ces eaux. Des campagnes ponctuelles, telles que celles du PNOC, le PNEC ou celles menées par l’IFREMER ou l’ORSTOM ont eu lieu depuis les années 1950, mais trop éloignées dans l’espace et dans le temps pour pouvoir rendre compte de la richesse et des cycles saisonniers. La mise en place de la Directive Cadre sur l’Eau en Guyane, a permis depuis 2009 de reprendre une partie des études liées à la zone littorale, il...

The present analysis of new and older collections (E. Chevreux) have permitted to describe 11 new species. 41 species are listed in the north-eastern Atlantic fauna. These are different arguments to think that Ampelisca groups was actually in speciation. Two groups issued from a phenetic analysis are discriminated by their apomorphic levels. More than of the third are endemic species. 21 species are present only in one of the five biogeographic region. 23 species are limited to the continental shelf, 34 live up to the first 1000 meters and 4 are bathyal. 2 species...

La réalisation des campagnes halieutiques Polka et Guyaviv2 au large des côtes guyanaises à la fin des années 80 a permis d’obtenir les relations biométriques qui ont été utilisées depuis cette date pour tous les calculs des captures (spectres par classe de taille) et des évaluations annuelles du stock de vivaneaux (Lutjanus purpureus) (Etienne Prévost 1989; E. Prévost et Tous 1989; Lampert 2012a) Plus de vingt ans après, nous pouvons nous poser la question de la pertinence de ces relations de nos jours. Des changements dans les paramètres de croissance de L. purpureus ne sont pas à exclure suite aux changements climatiques et à la pression de pêche exercée depuis quelques décennies. Ces changements pouvant alors se traduire par des variations dans les...

Acumulación de ácido araquidónico en fosfolípidos y triglicéridos y producción de prostaglandinas con relación a estrés térmico en semilla de ostión Crassostrea gigas
Provedor de dados: 5
Autores: Duran Encinas, Yazmin.
Crassostrea gigas is a marine invertebrate that inhabits the intertidal zone and therefore, is commonly exposed to multiple environmental stressors, including temperature. In recent years mass mortality events have been reported in Mexico in C. gigas associated with the increase in temperature during the summer. Organisms under thermal stress present an increase in prostaglandins (PG) production by cyclooxygenases (COX), an enzymatic route using arachidonic acid (ARA) present in the phospholipids (FL) of the cell membrane as substrate, but PG can also increase non-enzymatically by reactive oxygen species (ROS) that are produced during increased metabolism. It has been reported that some organisms exposed to stress accumulate a higher concentration of ARA...

Acute Oral Toxicity of Pinnatoxin G in Mice
Provedor de dados: 5
Autores: Sosa, Silvio; Pelin, Marco; Cavion, Federica; Herve, Fabienne; Hess, Philipp; Tubaro, Aurelia.
Pinnatoxin G (PnTx-G) is a marine cyclic imine toxin produced by the dinoflagellate Vulcanodinium rugosum, frequently detected in edible shellfish from Ingril Lagoon (France). As other pinnatoxins, to date, no human poisonings ascribed to consumption of PnTx-G contaminated seafood have been reported, despite its potent antagonism at nicotinic acetylcholine receptors and its high and fast-acting toxicity after intraperitoneal or oral administration in mice. The hazard characterization of PnTx-G by oral exposure is limited to a single acute toxicity study recording lethality and clinical signs in non-fasted mice treated by gavage or through voluntary food ingestion, which showed differences in PnTx-G toxic potency. Thus, an acute toxicity study was carried...

The synthesis of literature and personal observations permitted to show the main morphological physiological and genetic characteristics with relation to the mode of life of abyssal echinoderms. The large ventral sole is common among holothuroids and asteroids which creep on the bottom. The development of large podia and their ability to swim are particular to the abyssal family Elasipoda (Holothurioidea). The paper gives examples of opposite skeleton constitution either heavily or lightly calcified. The little knowledge about the biology of these animals shows the absence of a strict diet and of a particular mode of reproduction. [NOT CONTROLLED OCR]

Autores: Landrein, Sonia.
The determination of Mediterranean Salmonidae has been possible because of morphological and morphometrical studies and immunological and biochemical methods. It is evident that the 'sea trouts' belong to the species S. trutta fario and S. gairdneri irideus. These trouts have been acclimatized naturally to marine life. Experimental tests were undertaken in the laboratory, then in natural medium, to study the possibilities of trout acclimatization in sea water. They have confirmed the great adaptation qualities of these fishes to often extreme conditions. In the experiments undertaken in variable conditions, the influence of temperature and oxygen were exactly specified. Following these experiments, and other experiments realized in France and in other...

Summer mortality of the oyster result from the interaction of many factors. A respiratory assumption proposes a link between the supposed causes of the energy state, the cultivation methods and the medium. This work is focused towards the search for specific metabolic markers of environmental stresses. The cDNA of genes coding for PK and PEPCK were cloned and sequenced in order to detect their regulation level. The sediment nearness affects the state of energy reserves, the metabolic pathways of energy production implying a regulation of the PK. Face to the dissolved oxygen decline, oysters were oxyregulator but with a low regulation ability. In hypoxia, glycolysis was slowed down. PK activity was inhibited resulting from an increase in alanine sensitivity...

Adaptation génétique et détection de la sélection dans le cadre d'évolutions expérimentales
Provedor de dados: 5
Autores: Barthelemy, Clement.
Adaptation is a concept at the heart of the theory of evolution by natural selection. It designates both the process which allows the adjustment of the phenotypic trait of an individual to external environmental conditions and the state resulting from this process. In this context, genetic adaptation represents all of the molecular determinants of adaptation, which means, all of the mechanisms that drives adaptation of species at the molecular level. To study the evolutionary processes during adaptation, we can study the evolution of an experimental population in response to the conditions imposed by the experimenter (environmental, demographic, etc.): this is experimental evolution. When these experiments are coupled with high-throughput sequencing, the...

The new sustainable development data repository requires new analysis grids, in particular for factors accounted for in productive system typologies. This paper, based on the aquaculture example, analyses the diversity in aquaculture systems with respect to sustainable development. Various typologies are obtained by evaluating structural and functional approaches integrating variables related to production and regulation systems and to the territorial insertion of fish farms. Categories have been defined on a scale based on a set of five sites, which are representative of a wider range of aquaculture systems. Use of these categories goes beyond the local typologies and prepares a generic meta-typology classification for the systems. This generic...

Adaptation of copper community tolerance levels after biofilm transplantation in an urban river
Provedor de dados: 5
Autores: Fechner, Lise C.; Versace, Francois; Gourlay-france, Catherine; Tusseau-vuillemin, Marie-helene.
The Water Framework Directive requires the development of biological tools which can act as early-warning indicators of a sudden increase (accidental pollution) or decrease (recovery due to prevention) of the chemical status of aquatic systems. River biofilms, which respond quickly to modifications of environmental parameters and also play a key part in the functioning of aquatic ecosystems, are therefore good candidates to monitor an increase or a decrease of water pollution. In the present study, we investigated the biological response of biofilms transplanted either upstream (recovery) or downstream (deterioration of exposure levels) the urban area of Paris (France). Both modifications of Cu community tolerance levels and of global bacterial and...

Adaptation of digestive enzymes to dietary protein, carbohydrate and fibre levels and influence of protein and carbohydrate quality in Penaeus vannamei larvae (Crustacea, Decapoda)
Provedor de dados: 5
Autores: Le Moullac, Gilles; Van Wormhoudt, A; Aquacop, Aquacop.
Activity of digestive enzymes (trypsin, chymotrypsin and amylase) was studied in relation with food in Penaeus vannamei larvae first stages. Microparticles containing casein involved the decrease of soluble protein content and enzyme activities. Specific trypsin activity but not chymotrypsin was correlated (p&lt;1%) to casein level between 10 and 60% in microparticles. Cellulose fibres in food seemed to have little effect on digestive enzymes. Starch, between 1 and 20% in microparticles, had no influence on specific amylase activity. The effect of different feeding conditions were also tested on growth. No clear relationship between growth and enzyme is established since only trypsin is concerned in the case of a casein dose effect in the food. The protein...

Adaptation of the sea-bass (Dicentrarchus Labrax) to fresh water: Role of aquaporins and Na+/K+-ATPases
Provedor de dados: 5
Autores: Giffard Mena, I; Lorin Nebel, C; Charmantier, G; Castille, R; Boulo, Viviane.
Sea-bass (Dicentrarchus labrax) grow under different salinity regimes, from the open sea to lagoons and even rivers, but some mortality has been recorded in juvenile stages when exposed to low salinity water. Changes in water permeability of different osmoregulatory tissues could be the cause of reduction in blood osmotic pressure and death in some fish in fresh water (FW). In order to explore this condition, we have studied the changes of aquaporins (AQP1 and AQP3), alpha 1 and alpha 4 Na+/K(+-)ATPase transcript levels in the digestive tract, kidney and gills after a long-term exposure of juvenile sea-bass to sea water (SW) and FW fish able to survive in SW and FW are called SW-adapted fish (SWS), FW successfully-adapted fish (FWS) respectively, while...

There is considerable interest in the use of psychrotrophic bacteria for food biopreservation and in the understanding of cold adaptation mechanisms. The psychrotrophic biopreservative Lactococcus piscium strain CNCM I-4031 was studied for its growth behavior and proteomic responses after cold shock and during cold acclimation. Growth kinetics highlighted the absence of growth latency after cold shock, suggesting a very high promptness in cold adaptation, a behavior that has never been described before for lactic acid bacteria (LAB). A comparative proteomic analysis was applied with two-dimensional gel electrophoresis (2-DE), and upregulated proteins were identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

This paper explores the nature and dynamics of adaptation and resilience in the face of a diverse and varied environmental and ecological context using the case study of South Asia’s Indus Civilization (ca. 3000–1300 BC). Most early complex societies developed in regions where the climatic parameters faced by ancient subsistence farmers were varied but rain falls primarily in one season. In contrast, the Indus Civilization developed in a specific environmental context that spanned a very distinct environmental threshold, where winter and summer rainfall systems overlap. There is now evidence to show that this region was directly subject to climate change during the period when the Indus Civilization was at its height (ca. 2500–1900 BC). The Indus...

Autores: Leray, C.
The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

Listeria monocytogenes is it psychrotrophic food-borne pathogen. This organism is problematic for food production industry due to its ubiquitous distribution ill nature and its tolerance to condition of osmotic and chill stress. One common strategy employed by many bacteria and by L. monocytogenes for adaptation to osmotic stress is by the intracellular accumulation of compatible solutes. Two different types of adaptative reponses to low temperature have undertaken by L. monocytogenes. One of the responses is accomplished by adjusting membrane fluidity through alteration of the membrane fatty acid composition. A second response consists ill the accumulation of osmolytes. In this brief review we will focus on these general systems Which are Of particular...

This model is based on changes in intracellular metabolisable components depending an physiological responses of the cell when subjected to nutrient starvation, salinity stress and solar radiation. Following a strategy which takes into account short- and mid-term physiological adaptation and reversal processes, the cells can develop in different states: culturable (B-1), viable and definitively nonculturable (B-2), and reversibly dormant (B-3) cells. Model parameters were deduced either from original microcosm experiments, from literature data or calibration procedures. Validation of the model was...

How temperate forests will respond to climate change is uncertain; projections range from severe decline to increased growth. We conducted field tests of sessile oak (Quercus petraea), a widespread keystone European forest tree species, including more than 150,000 trees sourced from 116 geographically diverse populations. The tests were planted on 23 field sites in six European countries, in order to expose them to a wide range of climates, including sites reflecting future warmer and drier climates. By assessing tree height and survival, our objectives were twofold: (1) to identify the source of differential population responses to climate (genetic differentiation due to past divergent climatic selection versus plastic responses to ongoing climate...

Adaptive aspects of phenotypic plasticity in echinoderms
Provedor de dados: 5
Autores: Ebert, Ta.
Echinoderms show phenotypic plasticity in which variation in environmental conditions elicit graded reaction norms of morphological change. With the sea urchin Strongylocentrotus purpuratus under laboratory conditions, decreases in available food caused decreases in dry weights of the gonad and gut coupled with increases in the mass of Aristotle's lantern and length of the demi-pyramids. Spine clipping caused increased spine growth as well as decreases in the gut and gonad masses. Survival rate remained unchanged over a range of feeding and clipping treatments. In the field, at Sunset Bay, Oregon, well-fed sea urchins, with relatively small demi-pyramids, showed survival rates similar to poorly fed sea urchins that had large demi-pyramids. The wide range...

Adaptive behaviour of fishers to external perturbations: simulation of the Tasmanian rock lobster fishery
Provedor de dados: 5
Autores: Hamon, Katell; Frusher, Stewart; Little, L. Richard; Thebaud, Olivier; Punt, André E.
The rock lobster, Jasus edwardsii, lies on a global “hotspot” for climate change in the southeastern Australian state of Tasmania. The short-term effects of climate change are predicted to lead to an increasing exploitable biomass in the south and declining biomass in the north of the state. The future of the fishery is highly uncertain due to climate change, but also due to insecurities linked to the market conditions. The market for Tasmanian rock lobster is driven by the demand of a single market, China, which absorbs 75 % of the catch. This study examines how fishers can adapt to external perturbations that affect the social and economic viability of the fleet and the ecological dynamics of the stock. Three fleet dynamic models of increasing complexity...

Adaptive features of a bacteriolytic enzyme from the style of the mussel Choromytilus meridionalis in response to environmental fluctuations.
Provedor de dados: 5
Autores: Seiderer, L; Robb, F.
The extracellular digestive apparatus of bivalve molluscs consists of a crystalline style containing diverse degradative enzymes which are released during rotation and dissolution of the style. This paper reviews the occurrence of a temperature-regulated bacteriolytic enzyme in the black mussel Choromytilus meridionalis , which is an inhabitant of coastal reefs on the south and south west coast of South Africa. This agent is unable to lyse Micrococcus luteus or Escherichia coli , both of which are susceptible to lysis by a true lysozyme. It appears to have a restricted spectrum of activity which includes both free-living and kelp-associated gram-negative bacteria. In addition, the level of activity varies dramatically according to the environmental water...

Adaptive responses of tropical tuna purse-seiners under temporal regulations
Provedor de dados: 5
Autores: Torres-irineo, Edgar; Dreyfus-leon, Michel; Gaertner, Daniel; Salas, Silvia; Marchal, Paul.
The failure to achieve fisheries management objectives has been broadly discussed in international meetings. Measuring the effects of fishery regulations is difficult due to the lack of detailed information. The yellowfin tuna fishery in the eastern Pacific Ocean offers an opportunity to evaluate the fishers’ responses to temporal regulations. We used data from observers on-board Mexican purse-seine fleet, which is the main fleet fishing on dolphin-associated tuna schools. In 2002, the Inter-American Tropical Tuna Commission implemented a closed season to reduce fishing effort for this fishery. For the period 1992–2008, we analysed three fishery indicators using generalized estimating equations to evaluate the fishers’ response to the closure. We found...

Added water in frozen scallop muscles french specifications and methodology
Provedor de dados: 5
Autores: Loreal, Henri; Etienne, Monique.
The problem of foreign or added water is not really specifie of scallop muscles. Nevertheless, the astonishing ability of scallop muscle to soak up water makes the problem keen.  Heavy water additions that bring about excessive loss of water when thawing scallops are clearly a falsification.  Frequent abuses have been established in France in the 1980-1986 years, much so that the product might depreciate in the eyes of the consumers.  Consequently French importers and administrations decided to elaborate a standard in order to eliminate excessively soaked scallops and to preserve the brand image of the product.  Three points are defined in this standard :  . a sampling plan (codex plan NQA 6,5 S3) . the water/protein ratio on deglazed scallop muscles as...

Adding new pieces to the Azadinium (Dinophyceae) diversity and biogeography puzzle: Non-toxigenic Azadinium zhuanum sp. nov. from China, toxigenic A. poporum from the Mediterranean, and a non-toxigenic A. dalianense from the French Atlantic
Provedor de dados: 5
Autores: Luo, Zhaohe; Krock, Bernd; Mertens, Kenneth; Nezan, Elisabeth; Chomerat, Nicolas; Bilien, Gwenael; Tillmann, Urban; Gu, Haifeng.
The marine planktonic dinophyceaen genus Azadinium is a primary source of azaspiracids, but due to their small size its diversity may be underestimated and information on its biogeography is still limited. A new Azadinium species, A. zhuanum was obtained from the East China Sea and Yellow Sea of China by incubating surface sediments. Five strains were established by isolating single germinated cells and their morphology was examined with light microscopy and scanning electron microscopy. Azadinium zhuanum was characterized by a plate pattern of Po, cp, X, 4′, 2a, 6′′, 6C, 5S, 6′′′, 2′′′′, by a distinct ventral pore at the junction of Po, the first and fourth apical plates, and a conspicuous antapical spine. Moreover, Azadinium poporum was obtained for the...

Autores: Andrello, Marco; Mouillot, David; Somot, Samuel; Thuiller, Wilfried; Manel, Stephanie.
AimTo study the combined effects of climate change on connectivity between marine protected areas (MPAs) and larval supply to the continental shelf. LocationThe Mediterranean Sea, where sea surface temperatures are expected to strongly increase by the end of the 21st century, represents an archetypal situation with a dense MPA network but resource overexploitation outside. MethodsUsing an individual-based mechanistic model of larval transport, forced with an emission-driven regional climate change scenario for the Mediterranean Sea, we explored the combined effects of changes in hydrodynamics, adult reproductive timing and larval dispersal on the connectivity among MPAs and their ability to seed fished areas with larvae. ResultsWe show that, over the...

Additive rheology of complex granular flows

Autores: Trung Vo, Thanh; Nezamabadi, Saeid; Mutabaruka, Patrick; Delenne, Jean-yves; Radjai, Farhang.
Granular flows are omnipresent in nature and industrial processes, but their rheological properties such as apparent friction and packing fraction are still elusive when inertial, cohesive and viscous interactions occur between particles in addition to frictional and elastic forces. Here we report on extensive particle dynamics simulations of such complex flows for a model granular system composed of perfectly rigid particles. We show that, when the apparent friction and packing fraction are normalized by their cohesion-dependent quasistatic values, they are governed by a single dimensionless number that, by virtue of stress additivity, accounts for all interactions. We also find that this dimensionless parameter, as a generalized inertial number,...

Background Originating from Northeast Asia, the Pacific oyster Crassostrea gigas has been introduced into a large number of countries for aquaculture purpose. Following introduction, the Pacific oyster has turned into an invasive species in an increasing number of coastal areas, notably recently in Northern Europe.  Methods To explore potential adaptation of reproductive traits in populations with different histories, we set up a common garden experiment based on the comparison of progenies from two populations of Pacific oyster sampled in France and Denmark and their hybrids. Sex ratio, condition index and microarray gene expression in gonads, were analyzed in each progeny (n = 60).  Results A female-biased sex-ratio and a higher condition index were...

Addressing critical limitations of oyster (   Ostrea edulis   ) restoration: Identification of nature‐based substrates for hatchery production and recruitment in the field

Autores: Colsoul, Bérenger; Pouvreau, Stephane; Di Poi, Carole; Pouil, Simon; Merk, Verena; Peter, Corina; Boersma, Maarten; Pogoda, Bernadette.
The European flat oyster (Ostrea edulis) is an ecosystem engineer that provides important biogenic reef habitat with associated ecosystem functions and services. Most stocks have been commercially exploited and degraded; some are functionally extinct. Ecological restoration now aims to recover these degraded, damaged or destroyed ecosystems. Availability of seed oysters and substrate for successful larval recruitment has been identified as a major limiting factor for restoration projects in Europe. In substrate‐limited areas, restoration approaches have to involve the restoration of suitable substrates. The present study provides an evaluation of such potential substrate types. Various categories were investigated through hatchery and/or field experiments:...

Marine and coastal activities are closely interrelated, and conflicts among different sectors can undermine management and conservation objectives. Governance systems for fisheries, power generation, irrigation, aquaculture, marine biodiversity conservation, and other coastal and maritime activities are typically organized to manage conflicts within sectors, rather than across them. Based on the discussions around eight case studies presented at a workshop held in Brest in June 2019, this paper explores institutional approaches to move beyond managing conflicts within a sector. We primarily focus on cases where the groups and sectors involved are heterogeneous in terms of: the jurisdiction they fall under; their objectives; and the way they value ecosystem...

Addressing the measurement of particulate organic and inorganic phosphorus in estuarine and coastal waters
Provedor de dados: 5
Autores: Labry, Claire; Youenou, Agnes; Delmas, Daniel; Michelon, Pascale.
The speciation of particulate phosphorus (TPP) into inorganic (PIP) and organic phosphorus (POP), has been scarcely investigated in suspended particulate matter (SPM), contrary to numerous sediment studies. This work evaluates the actual capacity of methods for TPP, POP and PIP determination in SPM to measure efficiently and specifically each pool. Methods were tested on a range of plankton-associated organic and inorganic P compounds, on microalgal cultures and estuarine samples. Then results are specifically discussed reviewing P speciation in phytoplankton. For TPP analysis, the method of Solorzano and Sharp (1980) is recommended compared with that of Aspila et al. (1976), originally dedicated to sediment, as there is one step less, the protocol is more...

Adequacy of pseudo-direct georeferencing of terrestrial laser scanning data for coastal landscape surveying against indirect georeferencing

Autores: Jaud, Marion; Letortu, Pauline; Augereau, Emmanuel; Le Dantec, Nicolas; Beauverger, Mickael; Cuq, Veronique; Prunier, Christophe; Le Bivic, Rejanne; Delacourt, Christophe.
The georeferencing process is crucial to the accuracy of terrestrial laser scanner (TLS) data, in particular in the context of diachronic studies relying on multi-temporal surveys. The use of Ground Control Points in the georeferencing process can however be complex when confronted with the practical constraints of coastal surveying. A simple and quick alternative method called "pseudo-direct georeferencing" is proposed in the present paper. This method involves internal inclinometers to measure roll and pitch angles and a centimetric GPS to measure the position of the TLS center and the position of one backsight target. When assessing the transformational uncertainty by using a set of independent ground validation points for both classical indirect and...

Adéquation entre effort de pêche et ressource : les actions publiques dans le secteur des pêches
Provedor de dados: 5
Autores: Lantz, Frederic; Catanzano, Joseph; Weber, Jacques.
Fishing is an economic activity that, in a general way, requires the implementation of regulatory measures to avoid crises. This problem is linked to certain peculiarities inherent to fishing: the renewable and common character of the exploited resource, and the great variability of catches. Since the entire means of production coming into play in fishing is designated by the term fishing effort, various regulatory policies will become attached to the idea of fitting the level of the fishing effort to that of the exploited resource. After introducing the evolution of the fishing sector in an early section, we will study the main lines of EU policy in the sphere of fishing in section II. Section III will be devoted to the Multi-Year Orientation Programme...

Hyperthermophilic Archaea that thrive under harsh environments (elevated temperature, pH shifts, andionizing radiations) are supposed to be exposed to massive DNA damages. However, the mutations frequencies in hyperthermophilic Archaea are comparable with those of other microorganisms (1) indicating they are equipped with unique and efficient molecular mechanisms to ensure their genome integrity. DNA replication is an essential and conserved process among the three domains of life. DNA polymerases are central enzymes involved in the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain.

Adsorption of norovirus and ostreid herpesvirus type 1 to polymer membranes for the development of passive samplers
Provedor de dados: 5
Autores: Hubert, Francoise; Morga, Benjamin; Renault, Tristan; Le Guyader, Soizick.
Aims  This study was performed to develop passive sampling methodology for the detection of two viruses in seawater in the area of shellfish production, The Norovirus (NoV), a human pathogen implicated in gastroenteritis outbreaks linked to oyster consumption and the ostreid herpesvirus type 1 (OsHV-1) a virus associated with mass mortalities of Pacific oysters. Methods and Results  Commercially membranes were tested for their capacity to adsorb virus: Zetapor, gauze, nylon, low density polyethylene (LDPE) and Polyvinylidene difluoride (PVDF). Laboratory exposures of membranes to contaminated water samples (stool, sewage, seawater) were performed. Our data shown that the amount of NoV GII genome per membrane measured with qRT-PCR increased with the time of...

Autores: Suckling, Coleen C.; Clark, Melody S.; Richard, Joelle; Morley, Simon A.; Thorne, Michael A. S.; Harper, Elizabeth M.; Peck, Lloyd S.
This study examined the effects of long-term culture under altered conditions on the Antarctic sea urchin, Sterechinus neumayeri.Sterechinus neumayeri was cultured under the combined environmental stressors of lowered pH (-03 and -05 pH units) and increased temperature (+2 degrees C) for 2years. This time-scale covered two full reproductive cycles in this species and analyses included studies on both adult metabolism and larval development. Adults took at least 6-8months to acclimate to the altered conditions, but beyond this, there was no detectable effect of temperature or pH. Animals were spawned after 6 and 17months exposure to altered conditions, with markedly different outcomes. At 6months, the percentage hatching and larval survival rates were...

Adult and larval traits as determinants of geographic range size among tropical reef fishes
Provedor de dados: 5
Autores: Luiz, Osmar J.; Allen, Andrew P.; Robertson, D. Ross; Floeter, Sergio R.; Kulbicki, Michel; Vigliola, Laurent; Becheler, Ronan; Madin, Joshua S.
Most marine organisms disperse via ocean currents as larvae, so it is often assumed that larval-stage duration is the primary determinant of geographic range size. However, empirical tests of this relationship have yielded mixed results, and alternative hypotheses have rarely been considered. Here we assess the relative influence of adult and larval-traits on geographic range size using a global dataset encompassing 590 species of tropical reef fishes in 47 families, the largest compilation of such data to date for any marine group. We analyze this database using linear mixed-effect models to control for phylogeny and geographical limits on range size. Our analysis indicates that three adult traits likely to affect the capacity of new colonizers to survive...

Adult somatic progenitor cells and hematopoiesis in oysters
Provedor de dados: 5
Autores: Jemaa, Mohamed; Morin, Nathalie; Cavelier, Patricia; Cau, Julien; Strub, Jean Marc; Delsert, Claude.
Long-lived animals show a non-observable age-related decline in immune defense, which is provided by blood cells that derive from self-renewing stem cells. The oldest living animals are bivalves. Yet, the origin of hemocytes, the cells involved in innate immunity, is unknown in bivalves and current knowledge about mollusk adult somatic stem cells is scarce. Here we identify a population of adult somatic precursor cells and show their differentiation into hemocytes. Oyster gill contains an as yet unreported irregularly folded structure (IFS) with stem-like cells bathing into the hemolymph. BrdU labeling revealed that the stem-like cells in the gill epithelium and in the nearby hemolymph replicate DNA. Proliferation of this cell population was further...

Adult-mediated connectivity affects inferences on population dynamics and stock assessment of nursery-dependent fish populations
Provedor de dados: 5
Autores: Archarnbault, Benoit; Le Pape, Olivier; Baulier, Loic; Vermard, Youen; Veron, Matthieu; Rivot, Etienne.
We explore how alternative hypotheses on the degree of mixing among local subpopulations affect statistical inferences on the dynamics and stock assessment of a harvested flatfish population, namely, the common sole population in the Eastern Channel (ICES area VIId). The current paradigm considers a single, well-mixed, spatially homogeneous population with juveniles from all coastal nursery grounds along the French and UK coasts that contribute to a single adult population and one pool of eggs. Based on the available data and ecological knowledge, we developed a spatial Bayesian integrated life-cycle model that consists of three subpopulations (one near the UK coast and two near the French coast, denoted UK, West FR and East FR, respectively) supported by...

This work investigated adult-mediated connectivity and spatial population structure of sardine in the European Atlantic waters. The spatial and temporal progress of cohorts was modelled using abundance-at-age survey data by area in the period 2000 to 2016, covering the region from the northern Bay of Biscay to the eastern Gulf of Cadiz. A novel methodology was used to calculate indices of cohort movement between areas. Movement was relatively low between three large regions, the Bay of Biscay, the northern Spanish and Portuguese waters and the Gulf of Cadiz, each hosting a recruitment hotspot. On the other hand, one half of the sardines recruited in North Portugal and a quarter of those recruited in Southwest Portugal moved to northern Spanish waters and...

Advanced insights into magmatism and volcanism of the Mozambique Ridge and Mozambique Basin in the view of new potential field data
Provedor de dados: 5
Autores: Koenig, Matthias; Jokat, Wilfried.
P&gt;A new plate tectonic model is presented which describes the emplacement of the Mozambique Ridge off southeast Africa as the result of long lasting volcanic activity (140-122 Ma) during the initial opening between Africa and Antarctica. Thus, an oceanic origin for the Mozambique Ridge is proposed. This model is based on a new and systematic high resolution magnetic anomaly data set acquired across the Mozambique Ridge and throughout the Mozambique Basin. Data from the Mozambique Basin allow the identification of Mesozoic magnetic anomalies from M0r to M26 (124.61-155.3 Ma) with previously unmatched accuracy. Small-scale fracture zones are recognized by offsets of magnetic anomalies in the westernmost part of the basin. Additionally, a bend in the major...

Autores: Zabolotskikh, E.v.; Balashova, E.a.; Chapron, Bertrand.
An advanced method for sea ice concentration retrieval from satellite microwave radiometer measurements at frequencies near 90 GHz is presented. The method is based on the new approach for the determination of the tie points ― the polarization differences (PD) of the brightness temperatures (TB) of the ocean-atmosphere system (PDW) and the sea ice-atmosphere system microwave radiation (PDSI). The approach is based on the results of physical modeling of the sea ice – ocean – atmosphere TB and the analysis of the measurements of the Advanced Microwave Scanning Radiometer 2 (AMSR2) in the Arctic region. The TB simulation is carried out for the whole ranges of the Arctic atmospheric conditions and sea ice and ocean parameters. The method of sea ice...

Provedor de dados: 5
Autores: Ben Ismail, Dhouha Kbaier; Lazure, Pascal; Puillat, Ingrid.
Abstract—In marine sciences, time series are often nonlinear and nonstationary. Adequate and specific methods are needed to analyze such series. In this paper, an application of the Empirical Mode Decomposition method (EMD) associated to the Hilbert Spectral Analysis (HSA) is presented. Furthermore, EMD based Time Dependent Intrinsic Correlation (TDIC) analysis is applied to consider the correlation between two nonstationary time series. Four temperature time series obtained from automatic measurements in nearshore waters of the Réunion island are considered, recorded every ten minutes from July 2011 to January 2012. The application of the EMD on these series and the estimation of their power spectra using the HSA are illustrated. The authors identify...

Absolute salinity measurement of seawater has become a key issue in thermodynamic models of the oceans. One of the most direct ways is to measure the seawater refractive index which is related to density and can therefore be related to the absolute salinity. Recent advances in high resolution position sensitive devices enable us to take advantage of small beam deviation measurements using refractometers. This paper assesses the advantages of such technology with respect to the current state-of-the-art technology. In particular, we present the resolution dependence on refractive index variations and derive the limits of such a solution for designing seawater sensors well suited for coastal and deep-sea applications. Particular attention has been paid to...

Advancing our understanding of ocean biogeochemistry, biology, and ecosystems relies on the ability to make observations both in the ocean and at the critical boundaries between the ocean and other earth systems at relevant spatial and temporal scales. After decades of advancement in ocean observing technologies, one of the key remaining challenges is how to cost-effectively make measurements at the increased resolution necessary for illuminating complex system processes and rapidly evolving changes. In recent years, biogeochemical in situ sensors have been emerging that are threefold or more lower in cost than established technologies; the cost reduction for many biological in situ sensors has also been significant, although the absolute costs are still...

Advancing Santorini’s tephrostratigraphy: new glass geochemical data and improved marine-terrestrial tephra correlations for the past ∼360 kyrs

The island of Santorini in the Aegean Sea is one of the world’s most violent active volcanoes. Santorini has produced numerous highly explosive eruptions over at least the past ∼360 kyrs that are documented by the island’s unique proximal tephra record. However, the lack of precise eruption ages and comprehensive glass geochemical datasets for proximal tephras has long hindered the development of a detailed distal tephrostratigraphy for Santorini eruptions. In light of these requirements, this study develops a distal tephrostratigraphy for Santorini covering the past ∼360 kyrs, which represents a major step forward towards the establishment of a tephrostratigraphic framework for the Eastern Mediterranean region. We present new EPMA glass geochemical data...

Provedor de dados: 5
Autores: Coatanea, Denis; Nguyen-thuyet, Bruno; Febvre, Alain.
Dans les systèmes d'élevage intensif de crevettes Pénéides, la teneur en oxygène dissous du milieu d'élevage est un des éléments prioritaires à prendre en compte dans la gestion des bassins. Une aération d'appoint est nécessaire pour maintenir cette teneur en oxygène dissous dans une gamme de valeurs acceptables. Ce paramètre a été suivi sur deux fermes d'élevage intensif à Tahiti, dans différentes conditions de charge des bassins et dans différents schémas d'utilisation des aérateurs.

Aerial and snorkelling census techniques for estimating green turtle abundance on foraging areas: A pilot study in Mayotte Island (Indian Ocean)
Provedor de dados: 5
Autores: Roos, David; Pelletier, Dominique; Ciccione, Stéphane; Taquet, Marc; Hughes, George.
Monitoring the abundance of green turtles (Chelonia mydas) is necessary to assess population trends and risks of collapse. This note presents a study aimed at comparing three techniques for the direct estimation of green turtle numbers in their foraging habitats (seagrass beds and reef flats). The experiment was carried out at Mayotte Island, Western Indian Ocean. The techniques involved were surveys by snorkel, and aerial surveys using a microlight aircraft and a paramotor. Each technique had shortcomings and advantages. While each technique provided estimations of turtle numbers only surveys by snorkel permitted identification of species and sex, whenever visibility and turtle behaviour permitted. Along the shorelines, and over foraging areas, the...

Aerial surveys of bluefin tuna in the Western Mediterranean sea: retrospective, prospective, perspective
Provedor de dados: 5
Autores: Bonhommeau, Sylvain; Farrugio, Henri; Poisson, Francois; Fromentin, Jean-marc.
While the current stock status of bluefin tuna (BFT) has been considered as declining, there remain considerable data limitations for its stock assessment in the Mediterranean Sea. The collection of fishery-independent data reveals to be crucial to compensate for the lack of Mediterranean purse seine CPUE indices as well as to overcome a potential halt in the bluefin tuna fishery that would impede the monitoring of the stock and the comparison to reference points. Here we present a retrospective of aerial surveys that have been carried out since 2000. It includes the protocol as well as a retrospective of temporal and spatial distribution of detected schools. We then propose several perspectives that could improve the data collection method itself and the...

Aerial surveys to monitor bluefin tuna abundance and track efficiency of management measures
Provedor de dados: 5
Autores: Bauer, Robert; Bonhommeau, Sylvain; Brisset, Blandine; Fromentin, Jean-marc.
Conservation and management measures for exploited fish species rely on our ability to monitor variations in population abundance. In the case of the eastern stock of Atlantic bluefin tuna (ABFT), recent changes in management policies have strongly affected the reliability of fishery-dependent indicators due to drastic changes in fishing season/area, fisheries selectivity and strategy. However, fishery-independent indices of abundance are rare for large pelagic fish, and obtaining them is often costly and labor intensive. Here, we show that scientific aerial surveys are an appropriate tool for monitoring juvenile bluefin tuna abundance in the Mediterranean. We present an abundance index based on 62 aerial surveys conducted since 2000, using 2 statistical...

Aerobic capacities and swimming performance of polar cod (Boreogadus saida) under ocean acidification and warming conditions
Provedor de dados: 5
Autores: Kunz, Kristina Lore; Claireaux, Guy; Poertner, Hans-otto; Knust, Rainer; Mark, Felix Christopher.
Polar cod (Boreogadus saida) is an important prey species in the Arctic ecosystem, yet its habitat is changing rapidly: climate change, through rising seawater temperatures and CO2 concentrations, is projected to be most pronounced in Arctic waters. This study aimed to investigate the influence of ocean acidification and warming on maximum performance parameters of B. saida as indicators for the species' acclimation capacities under environmental conditions projected for the end of this century. After 4 months at four acclimation temperatures (0, 3, 6, 8 degrees C) each combined with two P-CO2 levels (390 and 1170 mu atm), aerobic capacities and swimming performance of B. saida were recorded following a U-crit protocol. At both CO2 levels, standard...

Aerobic scope explains individual variation in feeding capacity
Provedor de dados: 5
Autores: Auer, Sonya K.; Salin, Karine; Anderson, Graeme J.; Metcalfe, Neil B.
Links between metabolism and components of fitness such as growth, reproduction and survival can depend on food availability. A high standard metabolic rate (SMR; baseline energy expenditure) or aerobic scope (AS; the difference between an individual's maximum and SMR) is often beneficial when food is abundant or easily accessible but can be less important or even disadvantageous when food levels decline. While the mechanisms underlying these context-dependent associations are not well understood, they suggest that individuals with a higher SMR or AS are better able to take advantage of high food abundance. Here we show that juvenile brown trout (Salmo trutta) with a higher AS were able to consume more food per day relative to individuals with a lower AS....

Purpose. Despite an increasing interest in the use of inhalation for local delivery of molecules for respiratory diseases and systemic disorders, methods to deliver therapy through air-ways has received little attention for lung cancer treatment. However, inhalation of anticancer drugs is an attractive alternative route to systemic administration which results in limited concentration of the medication in the lungs, and triggers whole-body toxicity. In this study, we investigated the feasibility of nebulization for therapeutic antibodies, a new class of fully-approved anticancer drugs in oncology medicine.   Materials and methods. Cetuximab, a chimeric IgG1 targeting the epidermal growth factor receptor (EGER), was nebulized using three types of delivery...

Autores: Le Borgne, Eugéne; Le Pichon, Xavier.
The results of a precise and homogeneous aeromagnetic survey covering the Bay of Biscay, France, and the North Western Mediterranean are presented. The results suggest that the Bay of Biscay and the Mediterranean basin were created since the Triassic by drift of the adjacent continents. Indications are given about the times and geometries of opening of these basins. The implications of these results on the Mesozoic and Cenozoic tectonic history of South-Western Europe are important.

Dix-huit prélèvements d'aérosols ont été effectués en Manche Nord, soit en bordure de mer, soit à quelques milles au large, à l'aide d'un impacteur à cascade (5 étages). L'ensemble des données (concentrations de 8 éléments répartis en 6 classes granulométriques successives) est exploité par analyse factorielle des correspondances. Celle-ci permet de mettre en évidence de larges déformations dans les spectres granulométriques pour les éléments traceurs marin et terrestre (Na et Al). En opposition, les métaux résultant d'activité anthropique (Fe, Pb, Zn, Mn), ont des comportements beaucoup plus typés. Parmi ceux-ci, la présence du manganèse sur le site paraît être indépendante de celle des autres métaux et imputable à une seule source. Pb, Fe, Zn et cuivre...

The aim of the 20 Nautile dives of the recent Kanaut cruise was the study of the Kane Fracture Zone from its intersection with the Mid-Atlantic Ridge up to 80 km to the west. The dives have been conducted along four massifs located along the southern wall of the fracture valley. The flanks of the massifs consist of slightly tilted peridotites, gabbros and basalts, which have been exposed along normal and strike-slip major faults. No dike complex similar to that observed along the ZF Vema was observed The observed sections show pervasive cataclastic deformation and greenschist-facies metamorphic overprint.

AFLP-based genetic linkage maps of the blue mussel (Mytilus edulis)
Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Hecquet, Celine; Boudry, Pierre; Beaumont, A.
We report the construction of the first genetic linkage map in the blue mussel, Mytilus edulis. AFLP markers were used in 86 full-sib progeny from a controlled pair mating, applying a double pseudo-test cross strategy. Thirty-six primer pairs generated 2354 peaks, of which 791 (33.6%) were polymorphic in the mapping family. Among those, 341 segregated through the female parent, 296 through the male parent (type 1:1) and 154 through both parents (type 3:1). Chi-square goodness-of-fit tests revealed that 71% and 73% of type 1:1 and 3:1 markers respectively segregated according to Mendelian inheritance. Sex-specific linkage maps were built with mapmaker 3.0 software. The female framework map consisted of 121 markers ordered into 14 linkage groups, spanning...

African humid periods triggered the reactivation of a large river system in Western Sahara
Provedor de dados: 5
Autores: Skonieczny, Charlotte; Paillou, P.; Bory, A.; Bayon, Germain; Biscara, L.; Crosta, X.; Eynaud, F.; Malaize, B.; Revel, M.; Aleman, N.; Barusseau, J-p.; Vernet, R.; Lopez, S.; Grousset, F.
The Sahara experienced several humid episodes during the late Quaternary, associated with the development of vast fluvial networks and enhanced freshwater delivery to the surrounding ocean margins. In particular, marine sediment records off Western Sahara indicate deposition of river-borne material at those times, implying sustained fluvial discharges along the West African margin. Today, however, no major river exists in this area; therefore, the origin of these sediments remains unclear. Here, using orbital radar satellite imagery, we present geomorphological data that reveal the existence of a large buried paleodrainage network on the Mauritanian coast. On the basis of evidence from the literature, we propose that reactivation of this major paleoriver...

African monsoon enhancement during the penultimate glacial period (MIS 6.5 similar to 170 ka) and its atmospheric impact
Provedor de dados: 5
Autores: Tisserand, Amandine; Malaize, Bruno; Jullien, Elsa; Zaragosi, Sebastien; Charlier, Karine; Grousset, Francis.
A reconstruction of northwest African summer monsoon strength during the cold marine isotopic stage (MIS) 6 indicates a link to the seasonal migration of the Intertropical Convergence Zone (ITCZ). High-resolution studies of eolian dust supply and sea surface temperature recorded in marine core MD03-2705, on the Mauritanian margin, provide a better understanding about the penultimate glacial history of northwestern African aridity/humidity and upwelling coastal activity. Today, site MD03-2705 experiences increased upwelling and dust flux during the winter months, when the ITCZ is in a southerly position. Analyses of foraminifera isotopic composition suggest that during MIS 6.5 (180 - 168 ka) the average position of the ITCZ migrated north, marked by an...

Provedor de dados: 5
Autores: Doray, Mathieu; Stequert, Bernard; Taquet, Marc.
Daily growth increments measured in the otolith of Thunnus atlanticus were used to estimate the age and growth of individuals. which were sampled from an artisanal fishery operating around fish aggregating devices (FADs) moored off Martinique Island. In this study, 76 otoliths were analysed for fish ranging from 20 to 68 cm fork lengths (FL). The fish were caught using trolling lines at depths ranging from 0 to 10 m. Counts were made, under a light microscope, on the external part of the transverse section of the sagittae, from the primordium to the ventral edge. The mean coefficient of variation of the age reading was 2.4%. To validate readings, the number of increments for 11 individuals was counted using both optic and scanning electron microscopes. The...

Autores: Romdhani, Ahlem; Chater, Ines; Ktari, Mohamed Hédi; Dufour, Jean-louis; Mahe, Kelig.
The age of fish in a population is fundamental to most of the questions fishery biologists attempt to answer about that population. The aim of this study was to report the parameters of the weight-length relationship and to estimate the age and growth of Phycis phycis (Linnaeus, 1766) in Gulf of Tunis. A sample of 272 specimens of P. phycis was collected from the landings of the small-scale artisanal fisheries between September 2007 and June 2010. The total length (TL) ranged from 14 to 55.5cm and total weight (TW) from 45 to 1779g. Length-weight relationship were described by allometrically positive for the females (TW = 0.0083*TL3. 0703), males (TW= 0.0063*TL3.1471), and both sexes (TW= 0.0082*TL3. 0759).

Age and Growth of the lemon sole (Microstomus kitt) in the Celtic Sea and the North Sea
Provedor de dados: 5
Autores: Mahe, Kelig; Elleboode, Romain; Persohn, Cecile; Dufour, Jean-louis.
Age and growth of lemon sole (Microstomus kitt) were determined from 115 specimens collected in the Celtic Sea and in the North Sea in 2006 and 2007. Total length is ranged from 11 to 44 cm, while total weight varied between 12 and 1040 g. Age estimation was based on otoliths readings. The oldest male and female were estimated to be 9 years old. The length–weight relationships parameters for lemon sole in the Celtic Sea and in the North Sea were W=0.0043*TL3.2860 and W=0.0062*TL3.1505 respectively. Weight including both sexes increased with positive allometric growth. The von Bertalanffy growth equation in the North Sea was fitted on the basis of mean length-at-age data resulting in parameters values of TL∞ = 36.44 cm (S.E. = 0.484), K = 0.187 /y (S.E. =...

Age and growth of the striped seabream, Lithognathus mormyrus (Actinopterygii: Perciformes: Sparidae), in the central coast of Algeria, Mediterranean Sea
Provedor de dados: 5
Autores: Boufersaoui, Samira; Kassar, Abderrahmane; Mokrane, Zakia; Elleboode, Romain; Mahe, Kelig.
Background. Striped seabream, Lithognathus mormyrus (Linnaeus, 1758), is a bony fish, which has a high economic value on the Algerian coast. Because of the increasing fishing pressure, however, a close monitoring is recommended. The information about the biology of this species, occurring in the south-western Mediterranean Sea and especially in the north African coast, is very limited. The presently reported study provides new estimated data on age and growth parameters of striped seabream in Algeria. Materials and methods. A total of 449 specimens of L. mormyrus were sampled for 2 years (January 2013 to December 2014) from the commercial fishery in the central part of the Algerian coast. The samples were collected monthly. The fish ranged in size from...

Age- and quality-dependent DNA methylation correlate with melanin-based coloration in a wild bird
Provedor de dados: 5
Autores: Soulsbury, Carl D.; Lipponen, Anssi; Wood, Kristie; Mein, Charles A.; Hoffman, Joseph I.; Lebigre, Christophe.
Secondary sexual trait expression can be influenced by fixed individual factors (such as genetic quality) as well as by dynamic factors (such as age and environmentally induced gene expression) that may be associated with variation in condition or quality. In particular, melanin-based traits are known to relate to condition and there is a well-characterized genetic pathway underpinning their expression. However, the mechanisms linking variable trait expression to genetic quality remain unclear. One plausible mechanism is that genetic quality could influence trait expression via differential methylation and differential gene expression. We therefore conducted a pilot study examining DNA methylation at a candidate gene (agouti-related neuropeptide: AgRP) in...

Age, condition and dominance-related sexual ornament size before and during the breeding season in the black grouse     Lyrurus tetrix
Provedor de dados: 5
Autores: Harris, Sarah; Kervinen, Matti; Lebigre, Christophe; Pike, Thomas W.; Soulsbury, Carl D.
Male ornaments function as honest cues of male quality in many species and are subject to intra‐ and intersexual selection. These ornaments are generally studied during peak expression, however their size outside the breeding season may determine ultimate ornament size and costliness, and as such reproductive success. We investigated whether male black grouse Lyrurus tetrix eye comb size was related to age, condition and measures of male dominance before and during the breeding season. Total combined eye comb size began to increase ~70 days before the start of the breeding season. Adult males (aged ≥ 2 years old) had consistently larger eye combs than younger males (1 year old) both before and during the breeding season. Heavier and more dominant adult...

France and Canada have been working closely together for numerous years under the governance of The Northwest Atlantic Fisheries Organisation (NAFO) that regulates fisheries in the Northwest Atlantic. This workshop was the first step to achieve greater agreement in the estimation of age from calcified pieces between the scientific experts from those 2 countries. The goal of this project is to realize a calibration of the estimation of ages from cod (Gadus morhua) between France and Canada in order to optimize the precision of the data supplied by those countries for stock assessment purposes. There has been in the past an internal workshop for Atlantic Canada in 1997 on ageing fish and numerous workshops for Northeast Atlantic, more precisely for the...

Atlantic cod (Gadus morhua) in NAFO subDivision 3Ps are exploited and jointly managed by Canada and France. Assessments of stock status incorporate age determinations from both countries when dis-aggregating total catches into catch-at-age. An otolith exchange was initiated to evaluate the degree of consistency in the age determinations of Canadian and French personnel. Both graphical and statistical analysis clearly indicate differences in interpretation between Canadian and French readers, with ages assigned by Canadian personnel generally being one-year greater than those of participants from France. However, consistency in age determinations was relatively high within Canada and within France.

Age estimation and growth of some deep-sea fish from the northeast Atlantic ocean
Provedor de dados: 5
Autores: Allain, Valerie; Lorance, Pascal.
Age is a necessary parameter used in population dynamics to assess the state of exploited resources. This parameter is poorly known for most deep-sea species (depth &gt; 400 m). This work focused on age estimation from otoliths of Alepocephalus bairdii (Alepocephalidae), Coryphaenoides rupestris (Macrouridae), Helicolenus dactylopterus (Sebastidae) and Hoplostethus atlanticus (Trachichthyidae), which French fishery exploitation, off the west coasts of the British Isles, began the late 1980's. Considering otolith growth zones as annual, the four species all show high longevity: 38, 54, 43 and 130 years, respectively, together with slow growth. The differences in growth between sex were estimated and difficulties in accurately estimating the age were...

Age estimation in common sole Solea solea larvae: validation of daily increments and evaluation of a pattern recognition technique
Provedor de dados: 5
Autores: Lagardere, Françoise; Troadec, Herve.
Close similarities have been found between the otoliths of sea-caught and laboratory-reared larvae of the common sole Solea solea (L.), given appropriate temperatures and nourishment of the latter. But from hatching to mouth formation. and during metamorphosis, sole otoliths have proven difficult to read because the increments may be less regular and low contrast. In this study, the growth increments in otoliths of larvae reared at 12 degrees C were counted by light microscopy to test the hypothesis of daily deposition, with some results verified using scanning electron microscopy (SEM), and by image analysis in order to compare the reliability of the 2 methods in age estimation. Age was first estimated (in days posthatch) from light micrographs of whole...

Autores: Ngongang, Nicaise Blaise Tchuimegnie; Kamgang, Pierre; Chazot, Gilles; Agranier, Arnaud; Bellon, Herve; Nonnotte, Philippe.
The origin of the volcanism in the Cameroon Volcanic Line and the nature of its mantle sources are still highly controversial. We present major and trace element compositions as well as Sr-Nd-Pb-Hf isotopic results on mafic and intermediate lavas from the Bafang area in the central part of the Cameroon Volcanic Line. The lavas range from basanites and basalts to hawaiites and mugearites with an alkaline affinity and were emplaced between 10 and 6 Ma ago. The evolution from basalts and basanites to more differentiated rocks involved fractionation of olivine, clinopyroxene and Fe-Ti oxides, but the isotopic compositions show that crustal contamination processes affected some magmas during their ascent in the crust. Basalts and basanites originated from a...

Autores: Bacha, Mahmoud; Amara, Rachid; Benmansour, N; Brylinski, Jean-michel; Moali, A; Mahe, Kelig.
Age, growth and feeding of anchovy were studied for the first time from samples collected in the Benisaf Bay (west Algerian coast) during summer (spawning period) and autumn (recruitment period) 2007. Age structure and growth parameters were determined by otolith (sagitta) analyses. The von Bertalanffy growth function fitted to age-length data showed that growth was almost achieved during the first year of life. Significant growth difference was recorded between males and females. Growth parameters were for females (L∞=17,46 cm, k=0,31 per year and t0= -3,46 years) and for male (L∞=16,67 cm, k= 0,35 per year and t0= -3,26 years).

The growth and mortality of the brown meagre, Sciaena umbra from the Gulf of Tunis, were investigated using a sample of 276 specimens, ranging from 15.3 to 49.2 cm total length and from 43 to 1565 g total weight. Specimens were collected from artisanal fisheries between October 2008 and September 2011. Otoliths were extracted, thin cross-sections were realized and radii were measured. The log-linear morphometric relationships between total length-total weight and total length-otolith radius were significant (p &lt; 0.05), showed positive allometry (b=3.15) and isometry (b=0.90), respectively. The marginal analysis suggested that only one growth increment was deposited per year. The maximum age of the brown meagre was 22 years for males and 31 years for...

The age and growth of the Critically Endangered Atlantic goliath grouper Epinephelus itajara of equatorial French Guiana was determined by a non-lethal aging method using dorsal fin rays. Goliath grouper deposit 1 complete annulus per year, with the translucent zone of the annulus laid down at the beginning of the dry season (July). Two readers independently applied the method; there was full agreement between the two for 52% of the fish, and agreement of +/- 1 yr for 82%. Comparison of ages derived from paired samples of otoliths and fin rays were identical (n = 6). The mean age of goliath grouper was 4.2 yr (range = 1 to 17 yr; n = 229); 82% of the individuals were under the size/age of sexual maturity. Goliath grouper in French Guiana are larger at a...

Age, growth and mortality of the Starry weever Trachinus radiatus were studied for the first time from 214 individuals collected in the Gulf of Tunis between February 2014 and January 2016. The significant relationship between length-weight was observed for males (a = 0.011, b = 2.992, R2 = 0.981, n = 77) and females (a = 0.010, b = 3.036, R² =0.957, n = 109). Age was estimated by the observation of otoliths transverse thin sections. Age of individuals ranged from 1 to 15 years. The precision was measured by two age estimations from two experts and indicated a good agreement between them (PA = 85.6%, CV = 3.8% and IAPE = 4.1%).

Despite the high commercial value of the striped seabream Lithognathus mormyrus (Linnaeus, 1758) in the Gulf of Tunis, biological data on its age, growth and exploitation rate are lacking. With the aim of estimating growth parameters, 516 individuals, ranging from 6–27.5 cm total length and from 3.5–293.5 g total weight, were collected from the artisanal fishing fleet between February 2014 and July 2016. The somatic growth presented a positive allometry and was described by the equation TW = 6.54 10−3TL3.213. The monthly analysis of the marginal increment of the otoliths revealed that only one annulus was deposited per year. The estimated von Bertalanffy growth parameters were: L∞ = 30.18 cm, k = 0.303 year−1 and t0 = −1.42 years. Total and natural...

Age modelling of late Quaternary marine sequences in the Adriatic: towards improved precision and accuracy using volcanic event stratigraphy
Provedor de dados: 5
Autores: Lowe, John J.; Blockley, Simon; Trincardi, Fabio; Asioli, Alessandra; Cattaneo, Antonio; Matthews, I. P.; Pollard, M.; Wulf, S.
The first part of this paper presents a review of the problems that constrain the reliability of radiocarbon-based age models with particular focus on those used to underpin marine records. The reasons why radiocarbon data-sets need to be much more comprehensive than has been the norm hitherto, and why age models should be based on calibrated data only, are outlined. The complexity of the probability structure of calibrated radiocarbon data and the advantages of a Bayesian statistical approach for constructing calibrated age models are illustrated. The second part of the paper tests the potential for reducing the uncertainties that constrain radiocarbon-based age models using tephrostratigraphy. Fine (distal) ash layers of Holocene age preserved in...

Age précambrien de dolérites de la dorsale réguibat (Mauritanie)
Provedor de dados: 5
Autores: Dosso, Laure; Vidal, Philippe; Sichler, Bertrand; Bonifay, Alain.
Rb-Sr age determination on ten doleritic samples from the basement of Mauritania yield on average of 1 609   45 M.A. ( ?87 Rb = 1,42.10-   an- ). Four among the specimens have been dated by the K-Ar method with ages of 1.750, 1.610, 832 and 1.46 x M.Y. The radiometric data are interpreted as evidence for emplacement of the dolerites at the end of the Eburnean orogeny. [NOT CONTROLLED OCR]

Autores: Osman, Yassein A. A.; Mehanna, Sahar F; El-mahdy, Samia M; Mohammad, Ashraf S; Mahe, Kelig.
The age and growth of the haffara seabream, Rhabdosargus haffara (Forsskål, 1775) from Hurghada fishing area, Red sea, Egypt, were investigated using a sample of 466 specimens. The fish length varied between 12.7 and 27.2 cm and the weight from 38.1 to 293.2 g. Samples were collected from the artisanal fisheries during the fishing season from August 2018 to July 2019. The relationship between the body lengths (total, fork and standard length in cm) and the body weight (g) was found to be significant (p &lt; 0.05). The relationship between the body length and weight regarding the sex effect was insignificant for all samples (log W- log TL, ANCOVA, p &gt; 0.05). The relationship between length and weight was estimated by a power regression function, with a...

Age, spreading rates, and spreading asymmetry of the world's ocean crust
Provedor de dados: 5
Autores: Muller, R; Sdrolias, M; Gaina, C; Roest, Walter.
We present four companion digital models of the age, age uncertainty, spreading rates, and spreading asymmetries of the world's ocean basins as geographic and Mercator grids with 2 arc min resolution. The grids include data from all the major ocean basins as well as detailed reconstructions of back-arc basins. The age, spreading rate, and asymmetry at each grid node are determined by linear interpolation between adjacent seafloor isochrons in the direction of spreading. Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments. The age uncertainties for grid cells coinciding with marine magnetic anomaly identifications, observed or...

Age verification of north Atlantic sprat
Provedor de dados: 5
Autores: Moore, Claire; Lynch, Deirdre; Clarke, Maurice; Officer, Rick; Mills, Jane; Dufour, Jean-louis; Brophy, Deirdre.
Sprat is a pelagic species of increasing commercial interest in European waters, yet little is known about its biology or the drivers of its population fluctuations. As a result, the species is currently without an analytical assessment or forecast across much of the North East Atlantic. The objectives of this study were to: verify otolithbased age estimation of sprat; assess the precision, bias and reproducibility of these age estimates; and, determine the age structure of sprat within one North East Atlantic management unit (Celtic Seas ecoregion). Samples were collected over three years (2011, 2013 &amp; 2014) from both commercial catches and scientific surveys. Counts of daily increments in otoliths were used to establish when the first annulus was...

Ageage des buccins (Buccinum Undatum L) de la cote Ouest-Cotentin (France) à partir des statolithes
Provedor de dados: 5
Autores: Cochard, Marie-laure; Elleboode, Romain; Mahe, Kelig.
La baie de Granville dans le golfe normano-breton, située en Manche Est, représente la principale région française et européenne de pêche du buccin (Buccinum undatum) et génère une activité économique importante (environ 8000 tonnes et 12 millions € par an). Cette pêcherie est exploitée par 50 à 60 caseyeurs (arts dormants). Elle est très encadrée réglementairement (licences, quotas journaliers, taille minimale de capture). Bien que la production estimée soit relativement stable ces dernières années, la pêcherie reste vulnérable car localisée dans la partie méridionale de l’aire de répartition de l’espèce et pourrait être impactée défavorablement par un réchauffement climatique (Cf. derniers scenarii du GIEC). En ce sens, le buccin pourrait constituer une...

Age-dependence of cultured pearl grade and colour in the black-lipped pearl oyster Pinctada margaritifera
Provedor de dados: 5
Autores: Ky, Chin-long; Demmer, Jonathan; Blay, Carole; Lo, Cedrik.
Pinctada margaritifera is an economically important marine bivalve species for cultured pearl production in French Polynesian aquaculture. In order to evaluate the influence of donor oyster age on pearl quality traits, experiments were conducted over 6 years using both grafts and surgreffe operations. At harvest, 6 pearl quality traits were recorded and compared: surface defects, luster, grade, darkness level, and visual color. Analyzing the quality traits of pearls harvested in the initial graft process and those of pearls obtained from surgreffe experiments allowed a comparison of the influence of pearl sac cells originating from the initial mantle graft, which aged together with their recipient oysters. The results demonstrated a significant decrease...

Ageing mechanism and mechanical degradation behaviour of polychloroprene rubber in a marine environment: Comparison of accelerated ageing and long term exposure
Provedor de dados: 5
Autores: Le Gac, Pierre-yves; Le Saux, V.; Paris, M; Marco, Y.
Polymers are widely used in marine environments due to their excellent properties and good weathering resistance. Despite this extensive use, their long term behaviour in such an aggressive environment is still not well known. To assess the polymer durability within reasonable durations, it is essential to perform accelerated ageing tests to accelerate the degradation kinetics but without any modification of the degradation process. This study therefore proposes and validates accelerated ageing tests to study marine ageing of a silica-filled chloroprene rubber (CR) used for offshore applications. Several accelerated ageing protocols are investigated for temperatures ranging from 20 to 80 degrees C in renewed natural seawater. The ageing consequences are...

Ageostrophic instability in a rotating stratified interior jet
Provedor de dados: 5
Autores: Menesguen, Claire; Mcwilliams, J.c.; Molemaker, M. Jeroen.
Oceanic large- and meso-scale flows are nearly balanced in forces between Earth’s rotation and density stratification effects (i.e. geostrophic, hydrostatic balance associated with small Rossby and Froude numbers). In this regime advective cross-scale interactions mostly drive energy toward larger scales (i.e. inverse cascade). However, viscous energy dissipation occurs at small scales. So how does the energy reservoir at larger scales leak toward small-scale dissipation to arrive at climate equilibrium? Here we solve the linear instability problem of a balanced flow in a rotating and continuously stratified fluid far away from any boundaries (i.e. an interior jet). The basic flow is unstable not only to geostrophic baroclinic and barotropic instabilities,...

Ageostrophic instability in rotating, stratified interior vertical shear flows
Provedor de dados: 5
Autores: Wang, Peng; Mcwilliams, James C.; Menesguen, Claire.
The linear instability of several rotating, stably stratified, interior vertical shear flows (U) over bar (z) is calculated in Boussinesq equations. Two types of baroclinic, ageostrophic instability, AI1 and AI2, are found in odd-symmetric (U) over bar (z) for intermediate Rossby number (R-0). AI1 has zero frequency; it appears in a continuous transformation of the unstable mode properties between classic baroclinic instability (BCI) and centrifugal instability (CI). It begins to occur at intermediate R-0 values and horizontal wavenumbers (k, l) that are far from l = 0 or k = 0, where the growth rate of BCI or CI is the strongest. AI1 grows by drawing kinetic energy from the mean flow, and the perturbation converts kinetic energy to potential energy. The...

Agglomeration of wet particles in dense granular flows

Autores: Vo, Thanh Trung; Nezamabadi, Saeid; Mutabaruka, Patrick; Delenne, Jean-yves; Izard, Edouard; Pellenq, Roland; Radjai, Farhang.
In order to get insight into the wet agglomeration process, we numerically investigate the growth of a single granule inside a dense flow of an initially homogeneous distribution of wet and dry particles. The simulations are performed by means of the discrete element method and the binding liquid is assumed to be transported by the wet particles, which interact via capillary and viscous force laws. The granule size is found to be an exponential function of time, reflecting the conservation of the amount of liquid and the decrease of the number of available wet particles inside the flow during agglomeration. We analyze this behavior in terms of the accretion and erosion rates of wet particles for a range of different values of material parameters such as...

Aggregation processes of Tuna under Drifting Fish Aggregating Devices (DFADS) assessed through fisher's echosounder buoy in the Indian Ocean
Provedor de dados: 5
Autores: Baidai, Y; Dagorn, Laurent; Amande, Mj; Gaertner, Daniel; Capello, Manuela.
The aggregative behavior of tuna around floating object is widely exploited by the industrial purse-seine fishery, which deploy thousands of floating objects each year in all oceans in order to improve their catches. These fish aggregating devices (FADs) are generally equipped with echosounder buoys that can collect acoustic data, conferring to these devices the status of privileged observation platforms for the fish communities that aggregate. Using a classification model based on supervised learning algorithms trained on M3I buoy data, we were able to translate the acoustic data collected along the trajectories of 5748 drifting FADs newly deployed between 2016 and 2018 in the Indian Ocean into presence or absence of tuna aggregation. Analysis of the...

Catches of pelagic fish associated to anchored Fish Aggregating Devices have been responsible for increases in income, fish consumption, and even cultural identity of artisanal fishing communities in many developing countries worldwide. Nonetheless, in Brazil, aFAD fishing is still poorly developed and studied. In this experiment, FADs were anchored offshore the city of Recife (Northeastern Brazil) to investigate the potential of moored buoys in the aggregation of commercially important pelagic species near the coast, as an alternative fishing site for artisanal fishers. The behavior of acoustically tagged fish was investigated to assess whether they were attracted to the FADs and how long they remained associated to them. The results indicated that,...

Aggression supersedes individual oxygen demand to drive group air-breathing in a social catfish
Provedor de dados: 5
Autores: Killen, Shaun S.; Esbaugh, Andrew J.; Martins, Nicolas F.; Rantin, F. Tadeu; Mckenzie, David J.
1. Group-living is widespread among animals and comes with numerous costs and benefits. To date, research examining group-living has focused on trade-offs surrounding foraging, while other forms of resource acquisition have been largely overlooked. 2. Air-breathing has evolved in many fish lineages, allowing animals to obtain oxygen in hypoxic aquatic environments. Breathing air increases the threat of predation, so some species perform group air-breathing, to reduce individual risk. Within species, individual air-breathing can be influenced by metabolic rate as well as personality, but the mechanisms of group air-breathing remain unexplored. It is conceivable that keystone individuals with high metabolic demand or intrinsic tendency to breathe air may...

Autores: De Verdal, Hugues; O'Connell, Catherine Maeve; Mekkawy, Wagdy; Vandeputte, Marc; Chatain, Beatrice; Bégout, Marie-laure; Benzie, John A.h.
Given the strong effects of behavioural hierarchies on growth in many cultured species and the key role of feed efficiency in aquaculture economics, understanding the nature of the interaction of these variables is important for the sustainability of aquaculture. The relationship between agonistic behaviour, growth and feed efficiency in Nile tilapia, Oreochromis niloticus, was studied by rearing 120 fish in eight aquaria. Fish were video-recorded to estimate the occurrence of agonistic behaviour during a fasting and a refeeding period. Growth, feed intake and feed conversion efficiency (FCE - calculated as the inverse of feed conversion ratio (FCR)) were subsequently measured individually for each fish. Fish showed 58% less agonistic traits during the...

Autores: Miossec, Laurence.
The Water Framework Directive uses the “One-out, all-out” (OAOO) principle in assessing water bodies (i.e. the worst status of the elements used in the assessment determines the final status of the water body). Combination of multiple parameters within a biological quality element (BQEs) can be done in different ways. This study analysed several aggregation conditions within the BQE "Flora other than phytoplankton" (intertidal macroalgae, subtidal macroalgae, eelgrass beds and opportunistic blooms) using monitoring data collected along the Channel and Atlantic coastline.  Four aggregation criteria were tested on two sets of data collected between 2004 and 2014: OOAO, average, intermediate method between OOAO and average and a method taking into account an...

Agriculture, conchyliculture et circulation des eaux de surface : état actuel des recherches
Provedor de dados: 5
Autores: Chevallier, Claude; Masson, Daniel.
La qualité des eaux de surface constitue périodiquement un sujet de controverse et de polémiques entre professionnels agricoles et conchylicoles charentais. Le débat reste centré sur la valorisation agricole des zones de marais littoraux. La création croissante d'îlots de culture drainés, souvent à proximité immédiate des zones conchylicoles, suscite l'inquiétude quant à la qualité des eaux d'aval. Il nous a paru nécessaire d'établir un état succinct des connaissances en la matière afin d'éviter l'usage d'arguments parfois irrationnels et de favoriser le dialogue entre les partenaires ; mais il nous paraît tout aussi important de montrer que la qualité des eaux de surface, question essentielle pour l'aménagement régional dépasse le seul cadre des marais :...

Agulhas eddy fluxes in a 1/6 degrees Atlantic model
Provedor de dados: 5
Autores: Treguier, Anne-marie; Boebel, O; Barnier, B; Madec, G.
A 1/6degrees resolution primitive equation model of the Atlantic circulation is analyzed in the Agulhas region. The model has a realistic level of eddy kinetic energy, and produces anticyclonic Agulhas rings as well as cyclonic structures. In the model as well as in the data, ring trajectories undergo a transition between a turbulent character in the Cape Basin and a steady propagation in the rest of the South Atlantic. The topography of the Walvis Ridge does not seem to play a part in generating this contrast in the model. The model shows that cyclones are primarily generated from the negative shear vorticity side of the Agulhas Current as it leaves the coast, and they are most of the time paired with anticyclones in dipolar or tripolar structures....

Agulhas leakage as a key process in the modes of Quaternary climate changes
Provedor de dados: 5
Autores: Caley, Thibaut; Giraudeau, Jacques; Malaize, Bruno; Rossignol, Linda; Pierre, Catherine.
Heat and salt transfer from the Indian Ocean to the Atlantic Ocean (Agulhas leakage) has an important effect on the global thermohaline circulation and climate. The lack of long transfer record prevents elucidation of its role on climate changes throughout the Quaternary. Here, we present a 1,350-ka accumulation rate record of the planktic foraminiferal species Globorotalia menardii. We demonstrate that, according to previous assumptions, the presence and reseeding of this fauna in the subtropical southeast Atlantic was driven by interocean exchange south of Africa. The Agulhas transfer strengthened at glacial ice-volume maxima for every glacial-interglacial transition, with maximum reinforcements organized according to a 400-ka periodicity. The long-term...

Agulhas Leakage Predominantly Responds to the Southern Hemisphere Westerlies
Provedor de dados: 5
Autores: Durgadoo, Jonathan V.; Loveday, Benjamin R.; Reason, Chris J. C.; Penven, Pierrick; Biastoch, Arne.
The Agulhas Current plays a crucial role in the thermohaline circulation through its leakage into the South Atlantic Ocean. Under both past and present climates, the trade winds and westerlies could have the ability to modulate the amount of Indian-Atlantic inflow. Compelling arguments have been put forward suggesting that trade winds alone have little impact on the magnitude of Agulhas leakage. Here, employing three ocean models for robust analysisa global coarse-resolution, a regional eddy-permitting, and a nested high-resolution eddy-resolving configurationand systematically altering the position and intensity of the westerly wind belt in a series of sensitivity experiments, it is shown that the westerlies, in particular their intensity, control the...

Agulhas salt-leakage oscillations during abrupt climate changes of the Late Pleistocene
Provedor de dados: 5
Autores: Marino, Gianluca; Zahn, Rainer; Ziegler, Martin; Purcell, Conor; Knorr, Gregor; Hall, Ian R.; Ziveri, Patrizia; Elderfield, Henry.
An ensemble of new, high-resolution records of surface ocean hydrography from the Indian-Atlantic oceanic gateway, south of Africa, demonstrates recurrent and high-amplitude salinity oscillations in the Agulhas Leakage area during the penultimate glacial-interglacial cycle. A series of millennial-scale salinification events, indicating strengthened salt leakage into the South Atlantic, appear to correlate with abrupt changes in the North Atlantic climate and Atlantic Meridional Overturning Circulation (AMOC). This interhemispheric coupling, which plausibly involved changes in the Hadley Cell and midlatitude westerlies that impacted the interocean transport at the tip of Africa, suggests that the Agulhas Leakage acted as a source of negative buoyancy for...

Following a flooding event close to a shellfish production lagoon, 205 cases of gastroenteritis were linked to oyster consumption. Twelve stool samples from different individuals were collected. Analysis showed that eight samples were positive for multiple enteric viruses, and one stool sample had seven different enteric viruses. Analysis of shellfish implicated in the outbreak allowed detection of the same diversity of enteric viruses, with some viral genomic sequences being identical to those obtained from stool sample analysis. Shellfish were contaminated by as many as five different enteric viruses. For the first time in Europe, Aichi virus was identified in oyster samples. Shellfish samples collected over 3 weeks following the outbreak showed a...

Autores: De Pontual, Helene.
Existing methods to assess the biomass of reared oyster's stocks are ail based on aerial photographs and field data.  In this study, we propose an automatic processing of the digitized aerial photographs making use of advanced vision tools such as mathematical morphology.  The implemented a1gorithms are described. They give enough convincing results to suggest further developments.  However, this method requires the use of digital images. To this respect, a part of this paper deals with data acquisition problems. We particularly study the feasibility of using airborne video recording system. Such device should give a quite accurate information, easier to process than the classical aerial photographs.

A new photosynthetic, sand-dwelling marine dinoflagellate, Ailadinium reticulatum gen. et sp. nov., is described from the Jordanian coast in the Gulf of Aqaba, northern Red Sea, based on detailed morphological and molecular data. A. reticulatum is a large (53–61 μm long and 38–48 μm wide), dorsoventrally compressed species, with the epitheca smaller than the hypotheca. The theca of this new species is thick and peculiarly ornamented with round to polygonal depressions forming a foveate-reticulate thecal surface structure. The Kofoidian thecal tabulation is APC (Po, cp), 4′, 2a, 6′′, 6c, 4s, 6′′′, 1p, 1′′′′ or alternatively it can be interpreted as APC, 4′, 2a, 6′′, 6c, 4s, 6′′′, 2′′′′.

Air Backwash Efficiency on Organic Fouling of UF Membranes Applied to Shellfish Hatchery Effluents
Provedor de dados: 5
Autores: Cordier, Clemence; Stavrakakis, Christophe; Sauvade, Patrick; Coelho, Franz; Moulin, Philippe.
Among all the techniques studied to overcome fouling generated in dead-end filtration, the injection of air during backwashes proved to be the most effective. Indeed, shear stress engendered by the two-phase flow enhanced particle removal on membrane surface. This work aims to study the injection of air to drain the membranes before backwash. Firstly, the efficiency of this backwash procedure was evaluated during the ultrafiltration of seawater on a semi industrial pilot plant using different operating conditions. Then, the treatment of seawater, doped with oyster gametes to simulate the filtration of shellfish hatchery effluents, was performed to confirm the hydraulic performance of the air backwash. Indeed, the release of gametes, expulsed by exotic...

Air pollution and sea pollution are both impacting human health and all the natural environments on Earth. These complex interactions in the biosphere are becoming better known and understood. Major progress has been made in recent past years for understanding their societal and environmental impacts, thanks to remote sensors placed aboard satellites. This paper describes the state of the art of what is known about air pollution and focuses on specific aspects of marine pollution, which all benefit from the improved knowledge of the small-scale eddy field in the oceans. Examples of recent findings are shown, based on the global observing system (both remote and in situ) with standardized protocols for monitoring emerging environmental threats at the global...

Airborne remote sensing of ocean wave directional wavenumber spectra in the marginal ice zone
Provedor de dados: 5
Autores: Sutherland, Peter; Gascard, Jean-claude.
Interactions between surface waves and sea ice are thought to be an important, but poorly understood, physical process in the atmosphere-ice-ocean system. In this work, airborne scanning lidar was used to observe ocean waves propagating into the marginal ice zone (MIZ). These represent the first direct spatial measurements of the surface wave field in the polar MIZ. Data were compared against two attenuation models, one based on viscous dissipation and one based on scattering. Both models were capable of reproducing the measured wave energy. The observed wavenumber dependence of attenuation was found to be consistent with viscous processes, while the spectral spreading of higher wavenumbers suggested a scattering mechanism. Both models reproduced a change...

Airborne Remote Sensing of Wave Propagation in the Marginal Ice Zone
Provedor de dados: 5
Autores: Sutherland, Peter; Brozena, John; Rogers, W. Erick; Doble, Martin; Wadhams, Peter.
Airborne scanning lidar was used to measure the evolution of the surface wave field in the marginal ice zone (MIZ) during two separate wave events in the Beaufort Sea in October 2015. The lidar data consisted of a 2‐D field of surface elevation with horizontal resolutions between 17 and 33 cm, over a swath approximately 150‐220 m wide, centred on the ground track of the aircraft. Those data were used to compute directional wavenumber spectra of the surface wave field. Comparison with nearly collocated buoy data found the lidar and buoy measurements to be generally consistent. During the first event, waves travelling from open water into the ice were attenuated by the ice. The low spectral spreading and k7/4 spectral dependence of the attenuation was...

Air-sea CO2 flux in the Pacific Ocean for the period 1990-2009

Air-sea CO2 fluxes over the Pacific Ocean are known to be characterized by coherent large-scale structures that reflect not only ocean subduction and upwelling patterns, but also the combined effects of wind-driven gas exchange and biology. On the largest scales, a large net CO2 influx into the extratropics is associated with a robust seasonal cycle, and a large net CO2 efflux from the tropics is associated with substantial interannual variability. In this work, we have synthesized estimates of the net air-sea CO2 flux from a variety of products, drawing upon a variety of approaches in three sub-basins of the Pacific Ocean, i. e., the North Pacific extratropics (18-66 degrees N), the tropical Pacific (18 degrees S-18 degrees N), and the South Pacific...

Air-sea CO2 flux variability in frontal regions of the Southern Ocean from CARbon Interface OCean Atmosphere drifters
Provedor de dados: 5
Autores: Boutin, Jacqueline; Merlivat, L.; Henocq, C.; Martin, Nicolas; Sallee, Jean-baptiste.
Nine CARbon Interface OCean Atmosphere (CARIOCA) drifters were deployed in the Southern Ocean (south of the subtropical front, STF) between 2001 and 2006. They recorded 65 months of measurements in all seasons between 57 degrees S and 40 degrees S. Hydrological fronts detected by altimetry indicate that one buoy explored the polar zone (PZ) of the Atlantic Ocean and the western Indian Ocean; the remaining buoys explored the northern and southern parts of the subantarctic zone (SAZ) from the mid-Indian Ocean (73 degrees E) to the eastern Pacific Ocean (112 degrees W). The air-sea CO2 fluxes along the buoy trajectories are primarily driven by the spatial variability of the fugacity of CO2 in seawater, fCO(2): in the SAZ, they vary between -1.1 and -4.2 mol...

Air-sea CO2 fluxes and the controls on ocean surface pCO(2) seasonal variability in the coastal and open-ocean southwestern Atlantic Ocean: a modeling study
Provedor de dados: 5
Autores: Arruda, R.; Calil, P. H. R.; Bianchi, A. A.; Doney, S. C.; Gruber, N.; Lima, I.; Turi, G.
We use an eddy-resolving, regional ocean biogeochemical model to investigate the main variables and processes responsible for the climatological spatio-temporal variability of pCO(2) and the air-sea CO2 fluxes in the southwestern Atlantic Ocean. Overall, the region acts as a sink of atmospheric CO2 south of 30 degrees S, and is close to equilibrium with the atmospheric CO2 to the north. On the shelves, the ocean acts as a weak source of CO2, except for the mid/outer shelves of Patagonia, which act as sinks. In contrast, the inner shelves and the low latitude open ocean of the southwestern Atlantic represent source regions. Observed nearshore-to-offshore and meridional pCO(2) gradients are well represented by our simulation. A sensitivity analysis shows the...

Air-sea CO2 fluxes in a coastal embayment affected by upwelling: physical versus biological control
Provedor de dados: 5
Autores: Alvarez, M; Fernandez, E; Perez, Ff.
Water column pCO(2) and air-sea CO2 fluxes were studied during an 18-month period (May 1994-September 1995) in a coastal embayment affected by upwelling, located in the northwestern Iberian Peninsula (Ria de Vigo and adjacent shelf). Overall, the region acted as a net annual atmospheric CO, sink, with magnitude ranging from 0.54 mgC m(-2) d(-1) in the Ria estuary to 22 mgC m(-2) d(-1) offshore. During moderate upwelling and upwelling relaxation conditions the sampling area was a sink for atmospheric CO2. By contrast, during winter conditions and during intense upwelling the flux reversed towards the atmosphere. The relative influence of physical and biological processes on pCO(2) was evaluated using two different approaches: firstly, statistical analysis...

Air-sea disequilibrium enhances ocean carbon storage during glacial periods
Provedor de dados: 5
Autores: Khatiwala, S.; Schmittner, A.; Muglia, J.
The prevailing hypothesis for lower atmospheric carbon dioxide (CO2) concentrations during glacial periods is an increased efficiency of the ocean's biological pump. However, tests of this and other hypotheses have been hampered by the difficulty to accurately quantify ocean carbon components. Here, we use an observationally constrained earth system model to precisely quantify these components and the role that different processes play in simulated glacial-interglacial CO2 variations. We find that air-sea disequilibrium greatly amplifies the effects of cooler temperatures and iron fertilization on glacial ocean carbon storage even as the efficiency of the soft-tissue biological pump decreases. These two processes, which have previously been regarded as...

Air-Sea Turbulent Fluxes From a Wave-Following Platform During Six Experiments at Sea
Provedor de dados: 5
Autores: Bourras, Denis; Cambra, Remi; Marié, Louis; Bouin, Marie-noëlle; Baggio, Lucio; Branger, Hubert; Beghoura, Houda; Reverdin, Gilles; Dewitte, Boris; Paulmier, Aurélien; Maes, Christophe; Ardhuin, Fabrice; Pairaud, Ivane; Fraunié, Philippe; Luneau, Christopher; Hauser, Danièle.
Turbulent fluxes at the air‐sea interface are estimated with data collected in 2011 to 2017 with a low‐profile platform during six experiments in four regions. The observations were carried out with moderate winds (2‐10 m s‐1) and averaged wave heights of 1.5 m. Most of the time, there was a swell, with an averaged wave age (the ratio between wave phase speed and wind speed) being equal to 2.8±1.6. Three flux calculation methods are used, namely the eddy‐covariance (EC), the inertial‐dissipation (ID), and the bulk methods. For the EC method, a spectral technique is proposed to correct wind data from platform motion. A mean bias affecting the friction velocity (u*) is then evaluated. The comparison between EC u* and ID u* estimates suggests that a constant...

Introduction: This document is the End of Second Year internship report for Rennes University 1's Senior Math and Computer Science Modelisation Professional diploma. This two month internship was completed at the Brest IFREMER center at the Coastal Ecology department.  IFREMER participates, in the course of its institutional missions, in observation and coastal sea surveillance, in order to improve on the knowledge, protection methods and restoration of the marine environment. Marine phytoplankton proliferation is an important study subject because of its potential cause for nuisance, for men, consumers of sea products as well as for the ecosystem.  During Spring and Summer, shellfish become invariably unsuitable for consumption due to toxins produced by...

Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae), a new free-living marine nematode from the Condor Seamount (North-East Atlantic Ocean)
Provedor de dados: 5
Autores: Zeppilli, Daniela; Bongiorni, Lucia; Decraemer, Wilfrida; Vanreusel, Ann.
Epsilonematids are epifaunal nematodes characterized by an epsilon-shaped body and the presence of ambulatory setae, which are used in their locomotion. Nematodes belonging to this family were recently found in deep sea, especially in cold-water coral and seamount ecosystems. Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae) is described from sediments of the Condor Seamount (North-East Atlantic Ocean) at 206 m water depth. Its main features are a heterogeneous cuticule with large horn-like dorsal spines both in anterior and in posterior regions; the presence of eight subcephalic setae arranged in two rows and the ratio maximum/minimum body diameter larger than two. The taxonomic position of this new species within the genus is discussed...

Akimotoite in the Tenham meteorite: Crystal chemistry and high-pressure transformation mechanisms
Provedor de dados: 5
Autores: Ferroir, T; Beck, P; Van De Moortele, B; Bohn, Marcel; Reynard, B; Simionovici, A; El Goresy, A; Gillet, P.
The transformation of pyroxene to its high-pressure polymorph akimotoite (MgSiO3 ilmenite type structure) is documented in the shock-induced melt veins of the L6 Tenham chondrite. Four textural relationships between pyroxene and akimotoite are observed in former pyroxene grains entrained in the shear melt vein and in pyroxene grains attached to the wall of the melt vein. In one of the entrained enstatite grains the transformation to akimotoite is partial. One third of the grain is transformed to a polycrystalline aggregate of akimotoite with a scalloped interface with enstatite. Akimotoite (Fe0.4Mg1.24Ca0.07Na0.12Al0.14)(Si1.963Al0.037)O-6 is slightly enriched in Ca (CaO = 1.74%), Al and Na with respect to enstatite (CaO = 0.71%). Narrow bands of...

Growth and spirolide production of the toxic dinoflagellate Alexandrium ostenfeldii (Danish strain CCMP1773) were studied in batch culture and a photobioreactor (continuous cultures). First, batch cultures were grown in 450 mL flasks without aeration and under varying conditions of temperature (16 and 22 degrees C) and culture medium (L1, f/2 and L1 with addition of soil extract). Second, cultures were grown at 16 degrees C in 8 L aerated flat-bottomed vessels using L1 with soil extract as culture medium. Finally, continuous cultures in a photobioreactor were conducted at 18 degrees C in L1 with soil extract; pH was maintained at 8.5 and continuous stirring was applied. This study showed that A. ostenfeldii growth was significantly affected by temperature....

Autores: Rindi, F; Maltagliati, F; Rossi, F; Acunto, S; Cinelli, F.
Halophila stipulacea, a seagrass introduced into the Mediterranean Sea as a Lessepsian immigrant, is nowadays common in the eastern Mediterranean, and it was recently recorded in the western Mediterranean; very little information is available about the algal flora associated with this species. During a survey of a Halophila stipulacea stand at Vulcano Island (Eolian Islands, western Mediterranean), samples were collected at three depths (5 m, 15 m and 25 m) for identification of algal epiphytes. Thirty-six species of macroalgae were found. The epiflora of the leaves consisted of 20 species, the others being mixed with or entangled in the rhizomes. On the leaves, Ceramium tenerrimum, Dasya corymbifera, Polysiphonia cfr. tenerrima, Spyridia filamentosa,...

Algal food cultures at the centre océanologique du Pacifique
Provedor de dados: 5
Autores: AQUACOP.
The CENTRE OCEANOLOCIQUE DU PACIFIQUE (cap), a laboralory of the french agency CENTRE NATIONAL POUR L'EXPLOITATlON DES OCEANS (CNEXO), is located at Vairao in the southern part of TAHITI island, French Polynesia. Most of the island is surrounded with a coral reef delimitating a lagoon. Around the COP, the lagoon forms a NW-SE basin, 40 m of maximum depth, fed in oceanic water by the combing of the open-sea swell over the barrier reef, so that the renewal rate of the lagoon water is once every day or every second day according to the strength of the waves. Under those conditions, the sea water pumped at the COP offers similar features to the superficial oceanic water : annual temperature range 25.5 - 3O.1° C ; annual salinity range 34.2 - 36.5 ppt ; poor...

Algal food processing by Stegastes nigricans, an herbivorous damselfish: differences between an undisturbed and a disturbed coral reef site (La Reunion, Indian Ocean)
Provedor de dados: 5
Autores: Lison De Loma, Thierry; Harmelin-vivien, Mireille; Naim, Odile; Fontaine, Marie France.
There has, as yet, been little study of nutrient disturbance and its consequences on the functional biology of primary consumers in coral reefs. The processing of epilithic algal communities by the damselfish Stegastes nigricans was investigated at La Reunion, at two sites of a fringing reef, oligotrophic for one and eutrophic for the other. Differences between sites were analyzed in quantifying organic matter, organic carbon, nitrogen, and organic 'nutrients' (carbohydrate, lipid and protein) in the algal food, the digestive contents and the faeces of S. nigricans. In the disturbed site, algal turfs and digestive contents presented significantly higher organic matter, organic carbon, nitrogen and organic nutrient values. Absorption efficiency of total...

Algal growth on two sections of a fringing coral reef subject to different levels of eutrophication in Reunion Island
Provedor de dados: 5
Autores: Semple, S.
The temporal Variations in macroalgal coverage and biomass of two sectors of a fringing reef complex in Reunion Island, subject to different levels of nutrient enrichment, were compared over eight months. Little difference was detected in the back reef zone, but in the narrow coral strip zone the highly enriched site showed significantly higher coverage, biomass and diversity of macroalgae throughout the whole study period. Differences in the levels of nutrient enrichment of the reef waters of the two sites are implicated as potential reasons for the observed differences. The seasonal Variations of macroalgae on the reef, and aspects of several of the dominant algal species encountered are also discussed.

Algal toxins may accumulate in fish and shellfish and thus cause poisoning in consumers of seafood. Such toxins and the algae producing them are regularly surveyed in many countries, including Europe, North America, Japan and others. However, very little is known regards the occurrence of such algae and their toxins in most African countries. This paper reports on a survey of phytoplankton and algal toxins in Nigerian coastal waters.  Seawater samples were obtained from four sites for phytoplankton identification, on three occasions between the middle of October 2014 and the end of February 2015 (Bar Beach and Lekki in Lagos State, Port Harcourt in Rivers State and Uyo in Akwa Ibom State). The phytoplankton community was generally dominated by diatoms and...

The inhibitory effects of crude extracts of Zostera marina L and Zostera noltii Hornemann on the growth of the toxic red tide dinoflagellate Alexandrium catenella were investigated through bio-assays. Methanolic and aqueous extracts were prepared from fresh and detrital leaves of Z. marina and Z. noltii collected in the Thau lagoon and Arcachon bay (France). All the extracts exhibited significant inhibition of A. catenella growth, whatever the species and without the need of continuous addition of extracts. The effective concentrations (EC50) varied in the range 0.036-0.199 g L-1 for Z. noltii and 0.036-0.239 g L-1 for Z. marina. Methanolic extracts prepared from fresh plant tissues were the most potent, with EC50 of 0.036-0.039 and 0.036-0.045 g L-1, for...

A strong interest has been focused from several years on the algae pathway for energy production, especially for transportation fuels called third generation biofuel or G3 biofuel, and mainly from microalgae route, considering it could be a high potential alternative strategy for renewable energy and fuel production. Algae, and especially microalgae, present significant advantages compared with land resources, such as much higher productivity and lack of competition with food applications. Nevertheless, based on current knowledge, the production of an algae biomass for energy remains a difficult target to reach, due to the numerous existing hurdles such as the energetic yield and the economic positioning, without neglecting the environmental and societal...

Le développement croissant des cultures intensives d'algues unicellulaires marines pour l'aquaculture pose aujourd'hui le problème non seulement de la valeur nutritive de ces organismes mais également des ouvertures possibles vers un marché plus spécialisé en pharmacologie et cosmétologie. En effet, tant au niveau des propriétés étonnantes de certains produits d'excrétions (hydrates de carbone, biotoxines, antibiotiques) que des constituants de base (en particulier lipides et aminoacides) ou des complexes pigmentaires, il semble que peu d'applications semi industrielles aient dépassé l'échelle du laboratoire.

Alien species alert: Crassostrea gigas (Pacific oyster)
Provedor de dados: 5
Autores: Miossec, Laurence; Le Deuff, Rose-marie; Goulletquer, Philippe.
The Pacific oyster (Crassostrea gigas, Thunberg, 1793) is one of 20 species in the genus Crassostrea. Although native to the Japan/Korea region, C. gigas is a hardy species that has been introduced to a number of countries worldwide, including the US, Canada, the UK, France, Korea, China, New Zealand, Australia, South Africa, and South America, mainly for aquaculture purposes (Mann et al., 1991; Orensanz et al., 2002). As a result, C. gigas has become the leading species in world shellfish culture, with an estimated production of 4.6 million t in 2006 (FAO, 2008). Because C. gigas does not require additional food to sustain its growth, this species is relatively inexpensive and easy to produce. Its capacity to adapt to various environmental conditions and...

Didemnum vexillum Kott (2002) is a high-impact, globally-invasive, colonial tunicate species that is native to Japan (Lambert, 2009; Stefaniak et al., 2012). It is generally a temperate cold-water organism, and its introduced range currently includes New Zealand, the Netherlands, France, Ireland, United Kingdom, Spain, Italy, and both the west and east coasts of the United States and Canada (Lambert, 2009; Stefaniak et al., 2012; Tagliapietra et al., 2012; Ordóñez et al., 2015, Vercaemer et al., 2015). Like other invasive tunicates, D. vexillum has the capacity to reproduce rapidly, outcompete native species, deteriorate environmental integrity, and cause significant economic harm (Lambert, 2005; Blum et al., 2007; Daniel and Therriault, 2007; Langyel et...

Since the launch of the Sustainable Development Goals (SDGs) in 2015, several countries, funding organizations, environmental groups and research communities have pledged support and made commitment to help achieve these goals. SDG14: Life Below Water, for instance, has been embraced as the global goal for conservation and sustainable uses of the oceans, seas and marine resources. Among its many targets, SDG14b speaks directly to small-scale fisheries, calling for secured access to resources and markets for this sector. We argue that achieving SDG 14b requires a holistic approach encompassing several SDGs, including livelihoods, economic growth, community sustainability, strong institutions and partnerships. It is also important to align the SDG targets...

This document summaries major results about the diet of sole Solea solea and plaice Pleuronectes platessa in the English Channel, collected in the framework of the VARITROPH project. Both species have a similar diet, based on crustaceans, but plaice exhibit a larger diversity of secundary species (bivalves, annelids and echinoderms) than sole (annelids only). Diversity of the preys for plaice is explained by differences between size classes. Diet of small individuals is less diverse than the diet of large individuals. Trophic similarity between sole and plaice is also exhibited when comparing ontogenic changes of trophic levels, that are pretty similar for both species, and consistent with a diet based on small invertebrates.

The importance of predation by the whiting (Merlangius merlangus ) from the Celtic Sea has been studied by analysis of stomach contents. Eight hundred and thirteen whitings have been examined during 1984-1986 period. Fish food totalizes 97% of food. It is chiefly a swimming species: no cannibalism has been observed. The daily food index varies between 2 and 4% according to the length and the annual consumption on fishes of nominal catches (11230 t for 1983) would reach 135,000 t corresponding to species already fished for human consumption and the fish meal industry.

While pearl culture industry represents one of the dominant business sector of French Polynesia, it still entirely relies on natural reproduction and spat collection. A better knowledge of reproduction determinism is thus of particular interest for the black lip pearl oyster P. margaritifera. This work is based (i) on in situ studies of the pearl oyster diet and of the environmental determinism of reproduction; and (ii) on the application to the black lip pearl oyster of a bio-energetic and deterministic model of growth and reproduction based on the Dynamic Energy Budget theory. In Ahe atoll lagoon, plankton concentration and composition fluctuations were strongly linked to wind regimes. These variations had a great impact on the diet of pearl oysters...

Studies of the gill, digestive gland, and gonads of a large mytilid from the 13 degree N hydrothermal vent site have led to insights concerning the histology and functional anatomy of the gill, as well as the role of this organ in the nutrition of the bivalve. From observations of the digestive gland, it is concluded that this mytilid ingests bacteria, as well as other microscopic organisms of hydrothermal vent and euphotic surface water origin. Histology of the gonad reveals that reproduction in this species is similar to that of shallow-water coastal bivalves.

Alimentation expérimentale de l'huître Crassostrea gigas à l'aide de navicules bleus Haslea ostrearia (Simonsen) de différentes tailles
Provedor de dados: 5
Autores: Barille, Laurent; Bougrier, Serge; Geairon, Philippe; Robert, Jean-michel.
The influence on the feeding physiology (clearance, filtration, ingestion, absorption) of the Japanese oyster Crassostrea gigas of low concentrations of suspended particulate matter (SPM ranging from 2 to 20 mg.l-l) and high food quality (mean organic fraction =54 %) was studied in the laboratory. Experimental diets were made up with three strains of the "blue diatom" Haslea ostrearia, which is responsible of the greening of oyster-ponds. The strains were characterized by different sizes (48, 65 and 98 µm respectively) but possessed the same density and biochemical composition. Clearance rate was found constant at 2.2 1.h(-l).g-l dry weight and therefore was not influenced by increasing seston load. Pseudofaeces production was observed for SPM...

Aliphatic hydrocarbons and triterpenes of the Congo deep sea fan
Provedor de dados: 5
Autores: Mejanelle, Laurence; Riviere, Beatrice; Pinturier, Laurence; Khripounoff, Alexis; Baudin, Francois; Dachs, Jordi.
Hydrocarbons were analyzed in sediments from the Congo River deep-sea fan, from the Congo River, and in sinking particles collected by sediment traps 40 m above the sediment. Studied sites encompassed three lobes of decreasing age of formation along the canyon: sites A, F and C and a another lobe system, disconnected from the active channel since 4 ka, Site E. Terrestrial long-chain odd n-alkanes were dominant in all sediments of the lobe system. Unsaturated terpenoids sourced by higher plants, such as gammacerene, lupene, ursene and oleanene, were also detected. At site C, characterized by high accumulation rates (10–20 cm yr−1), the organic matter spends less time in the oxic layer than at other sites and high phytadiene concentrations (10 to 17 μg...

Alkaline-extractable silicon from land to ocean: A challenge for biogenic silicon determination
Provedor de dados: 5
Autores: Barao, Lucia; Vandevenne, Floor; Clymans, Wim; Frings, Patrick; Ragueneau, Olivier; Meire, Patrick; Conley, Daniel J.; Struyf, Eric.
The biogeochemical cycling of silicon (Si) along the land-to-ocean continuum is studied by a variety of research fields and for a variety of scientific reasons. However, there is an increasing need to refine the methodology and the underlying assumptions used to determine biogenic silica (BSi) concentrations. Recent evidence suggests that contributions of nonbiogenic sources of Si dissolving during alkaline extractions, not corrected by standard silicate mineral dissolution correction protocols, can be substantial. The ratio between dissolved Si and aluminum (Al) monitored continuously during the alkaline extraction can be used to infer the origin of the Si fractions present. In this study, we applied both a continuous analysis method (0.5 M NaOH) and a...

Alkenone distributions in the North Atlantic and Nordic sea surface waters
Provedor de dados: 5
Autores: Sicre, Ma; Bard, E; Ezat, U; Rostek, F.
The C(37)-C(39) alkenones were quantified in suspended particulate matter obtained from the surface waters of the North Atlantic, including the Nordic seas, over a temperature range of 4degrees20 C. U(37)(K') values were linearly correlated to temperature over the entire range covered by our data set, i.e., 420 C (U(37)(K') = 0.027T + 0.036, r(2) = 0.97). The compilation of water column data from the Atlantic, Pacific, and Southern Ocean and Mediterranean Sea suggests that the linear model may not be the best function for fitting U(37)(K') and in situ temperature values. It also shows that suspended matter data from warm waters (T &gt;20degreesC) are still needed to constrain the equation of the global curve. High abundances of C(37: 4) were found in the...

Alkenone unsaturation in surface sediments from the eastern equatorial Pacific: Implications for SST reconstructions
Provedor de dados: 5
Autores: Kienast, M.; Macintyre, G.; Dubois, N.; Higginson, S.; Normandeau, C.; Chazen, C.; Herbert, T. D.
Significant uncertainties persist in the reconstruction of past sea surface temperatures in the eastern equatorial Pacific, especially regarding the amplitude of the glacial cooling and the details of the post-glacial warming. Here we present the first regional calibration of alkenone unsaturation in surface sediments versus mean annual sea surface temperatures (maSST). Based on 81 new and 48 previously published data points, it is shown that open ocean samples conform to established global regressions of U-K' 37 versus maSST and that there is no systematic bias from seasonality in the production or export of alkenones, or from surface ocean nutrient concentrations or salinity. The flattening of the regression at the highest maSSTs is found to be...

Alkenones in the Northwestern Mediterranean sea: interannual variability and vertical transfer
Provedor de dados: 5
Autores: Sicre, Ma; Ternois, Y; Miquel, Jc; Marty, Jc.
C-37 alkenone fluxes were measured with sediment traps at 200 m depth over the years 1989/1990 and 1993/1994 to assess the interannual variability of the alkenone flux from the surface waters of the Mediterranean Sea. Fall and spring were identified as the high flux periods. SST estimates derived from the U-37(K) index indicated 50 m and 30 m as major production depths in spring and fall, respectively. Althought interannual variation of alkenone fluxes was notable, the seasonality and depth of production appeared to be recurrent features of the coccolithophorid cycle of production. Alkenone fluxes at 1000 m measured over the year 1993/1994 were about 5 times lower than at 200 m and show no evidence of preferential preservation relative to the organic...

Malaria and schistosomiasis are major infectious causes of morbidity and mortality in the tropical and sub-tropical areas. Due to the widespread drug resistance of the parasites, the availability of new efficient and affordable drugs for these endemic pathologies is now a critical public health issue. In this study, we report the design, the synthesis and the preliminary biological evaluation of a series of alkoxyamine derivatives as potential drugs against Plasmodium and Schistosoma parasites. The compounds (RS/SR)-2F, (RR/SS)-2F, and 8F, having IC50 values in nanomolar range against drug-resistant P. falciparum strains, but also five other alkoxyamines, inducing the death of all adult worms of S. mansoni in only 1 h, can be considered as interesting...

Allelochemicals from Alexandrium minutum induce rapid inhibition of metabolism and modify the membranes from Chaetoceros muelleri
Provedor de dados: 5
Autores: Long, Marc; Tallec, Kevin; Soudant, Philippe; Le Grand, Fabienne; Donval, Anne; Lambert, Christophe; Sarthou, Geraldine; Jolley, Dianne F.; Hegaret, Helene.
Allelochemical interactions are likely to be a contributing factor explaining the success of large blooms of the harmful marine dinoflagellate Alexandrium, however, the physiological mechanisms of allelochemical interactions remain poorly described. Here we investigated the sub-lethal effects (on an hourly scale) of a filtrate containing allelochemicals from Alexandrium minutum on the physiology of the common diatom Chaetoceros muelleri. The filtrate induced deleterious effects to the diatom physiology within only 30 min of exposure. Esterase activity and photosynthesis were drastically inhibited, with up to 34% of the population being metabolically inactive and up to 30% reduction in photosystem II quantum yield when exposed to the filtrate. In addition,...

Allelochemicals of Alexandrium minutum: Kinetics of membrane disruption and photosynthesis inhibition in a co-occurring diatom
Provedor de dados: 5
Autores: Long, Marc; Peltekis, Alexandra; González-fernández, Carmen; Hégaret, Helene; Bailleul, Benjamin.
Allelopathy is an efficient strategy by which some microalgae can outcompete other species. Allelochemicals from the toxic dinoflagellate Alexandrium minutum have deleterious effects on diatoms, inhibiting metabolism and photosynthesis and therefore give a competitive advantage to the dinoflagellate. The precise mechanisms of allelochemical interactions and the molecular target of allelochemicals remain however unknown. To understand the mechanisms, the short-term effects of A. minutum allelochemicals on the physiology of the diatom Chaetoceros muelleri were investigated. The effects of a culture filtrate were measured on the diatom cytoplasmic membrane integrity (polarity and permeability) using flow-cytometry and on the photosynthetic performance using...

Allis shad (Alosa alosa) exhibit an intensity-graded behavioral response when exposed to ultrasound
Provedor de dados: 5
Autores: Wilson, M; Acolas, M; Begout, Marie-laure; Madsen, P; Wahlberg, M.
Most fish cannot hear frequencies above 3 kHz, but a few species belonging to the subfamily Alosinae (family Clupeidae) can detect intense ultrasound. The response of adult specimens of the European allis shad (Alosa alosa) to sinusoidal ultrasonic pulses at 70 and 120 kHz is tested. The fish showed an intensity-graded response to the ultrasonic pulses with a response threshold between 161 and 167 dB re 1 mu Pa (pp) for both frequencies. These response thresholds are similar to thresholds derived from juvenile American shad (Alosa sapidissima) in previous studies, supporting the suggestion that these members of Alosinae have evolved a dedicated ultrasound detector adapted to detect and respond to approaching echolocating toothed whales.

The aim of this thesis is to improve knowledge on mechanisms involved in the response to nitrogen limitation and in lipid accumulation in the microalgae haptophyte Tisochrysis lutea. The wild type strain and a lipid accumulating mutant strain were grown under different nitrogen limitation and starvation and analyzed by functional genomics. Four genes of high-affinity nitrate/nitrite transporter (Nrt2) were identified and characterized to reveal the mechanisms involved in mineral absorption in this species. Transcriptomes of both strains were sequenced and proteins affected by nitrogen starvation and differentially expressed between the two strains were identified. We so identified the functions regulated by nitrogen deficiency and potentially involved in...

Autores: Ben Khemis, Ines; Gisbert, Enric; Alcaraz, Carles; Zouiten, Dora; Besbes, Raouf; Zouiten, Amina; Masmoudi, Ahmed Slaheddine; Cahu, Chantal.
Allometric growth and ontogeny were studied in thick-lipped grey mullet Chelon labrosus reared in mesocosms from 1 to 71 day post hatching (dph). Multivariate allometric analysis of morphometric growth distinguished three distinct developmental stanzas separated by two morphometric metamorphosis lengths (L-m1=4.46 +/- 0.06mm; L-m2= 28.56 +/- 1.04mm). Body mass growth also showed three distinct episodes separated by two inflections, correlated with morpho-functional changes. First episode concerned pre-flexion larvae and ended around 4.5mm-L-T (14-dph), coinciding with estimated L-m1. It was distinguished by reduced growth, but intense morphogenesis and differentiation processes. Organogenesis and allometric changes indicated that development priorities...

Alpha and beta diversity patterns of polychaete assemblages across the nodule province of the eastern Clarion-Clipperton Fracture Zone (equatorial Pacific)
Provedor de dados: 5
Autores: Bonifácio, Paulo; Martinez-arbizu, Pedro; Menot, Lenaick.
In the abyssal Equatorial Pacific Ocean, most of the seafloor of the Clarion-Clipperton Fracture Zone (CCFZ), a 6 million km2 polymetallic nodule province, has been preempted for future mining. In light of the large footprint that mining would leave, and given the diversity and the vulnerability of the abyssal fauna, the International Seabed Authority has implemented a regional management plan that includes the creation of nine areas of particular environmental interest (APEIs) located at the periphery of the CCFZ. The APEIs were defined based on the best – albeit very limited – scientific knowledge for the area. The fauna and habitats in the APEIs are unknown, as are species' ranges and the extent of biodiversity across the CCFZ. As part of the Joint...

Autores: Vignet, Caroline.
Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants (POPs) which are found in complex mixtures in the environment including aquatic ecosystems. They adsorb on particles, accumulate in sediment and in the first link of the food web. The aim of this study was to measure long term effects of PAH scontamination on a vertebrate model: the zebrafish. In a first study, embryos were exposed on natural sediment spiked with 3 individual PAH (phenanthrene, pyrene and benzo[a]pyrene) during the first four days of their development. In a second study, to evaluate the consequences of long-term chronic exposure to PAHs, zebrafish were exposed, from their first meal (5 days post fertilisation) until they became reproducing adults, to diets spiked...

Alteration, fractional crystallization, partial melting, mantle properties from trace elements in basalts recovered in the north atlantic
Provedor de dados: 5
Autores: Bougault, Henri; Joron, Jean-louis; Treuil, Michel.
.-Alkali metals prove to be very sensitive to alteration process even if this process is moderate. It is very difficult to use these elements to trace magmatic processes since their concentration may Vary within an homogeneous "unaltered" unit. From all the basaltic units investigated, a classification of "low partition coefficient" elements is presented (Sc, Ti, V, Y, Zr, Nb, La-Tb , Hf, Ta, Th) . The incompatible elements ratios (Y/Tb, Zr/Hf, Nb/Ta) are constant in the samples studied and are nearly equal to the same ratios in chondrites. This is consistent with the existence of an homogeneous primordial mantle at the scale of the North Atlantic, compatible with a chondritic composition of the earth. [NOT CONTROLLED OCR]

Altered volcanic deposits as basal failure surfaces of submarine landslides
Provedor de dados: 5
Autores: Miramontes, Elda; Sultan, Nabil; Garziglia, Sebastien; Jouet, Gwenael; Pelleter, Ewan; Cattaneo, Antonio.
One of the main concerns regarding the development of submarine landslides is the role played by weak layers in the failure process and, in particular, their impact in terms of volume, shape, and evolution of mass movements. In the present study we identified a weak layer in the eastern margin of the Corsica Trough (northern Tyrrhenian Sea) that formed the basal failure surface of the Pianosa Slump at 42–50 ka. This layer is characterized by high water content, high plasticity, high compressibility, and post-peak strain softening behavior (i.e., strength loss with increasing strain). These specific mechanical and sedimentological properties seem to be related to the presence of analcime zeolites with a concentration of 2–4% in the muddy sediment. Zeolites...

Discovery after discovery, host-associated microbiota reveal a growing list of positive effects on host homeostasis by contributing to host nutrition, improving hosts’ immune systems and protecting hosts against pathogens. In that context, a collection of oyster associated bacteria producing antibacterial compounds have been established to evaluate their role in non-host-derived immunity. Here, we described alterins; potent anti-Gram negative compounds produced by Pseudoalteromonas hCg-6 and hCg-42 isolated from different healthy oyster hemolymph. The strains hCg-6 and hCg-42 produce a set of at least seven antibacterial compounds, ranging from 926 to 982 Da structurally characterized as cyclolipopeptides (CLPs).

Alternating Influence of Northern Versus Southern-Sourced Water Masses on the Equatorial Pacific Subthermocline During the Past 240 ka
Provedor de dados: 5
Autores: Rippert, Nadine; Max, Lars; Mackensen, Andreas; Cacho, Isabel; Povea, Patricia; Tiedemann, Ralf.
The eastern equatorial Pacific (EEP) is a key area to understand past oceanic processes that control atmospheric CO2 concentrations. Many studies argue for higher nutrient concentrations by enhanced nutrient transfer via Southern Ocean Intermediate Water (SOIW) to the low-latitude Pacific during glacials. Recent studies, however, argue against SOIW as the primary nutrient source, at least during early Marine Isotope Stage 2 (MIS 2), as proxy data indicate that nutrients are better utilized in the Southern Ocean under glacial conditions. New results from the subarctic Pacific suggest that enhanced convection of nutrient-rich Glacial North Pacific Intermediate Water (GNPIW) contributes to changes in nutrient concentrations in equatorial subthermocline water...

1. Transitional waters, described as critical transition zones because of their position at terrestrial, freshwater and marine interfaces, provide essential goods and services to the biosphere including human populations. These ecotones face increasing human influence mainly due to population density increase in coastal areas.   2. Transitional water bodies have, to date, received little attention in the development of ecological status indicators, this is a critical deficiency when trying to meet the Water Framework Directive objective of all significant water bodies achieving good ecological status by the year 2015.   3. In order to assess changes in transitional water communities many taxonomic-based indicators have already been proposed but there are a...

The aim was to identify and study the antibiofilm protein secreted by the marine bacterium Pseudoalteromonas sp. 3J6. The latter is active against marine and terrestrial bacteria, including Pseudomonas aeruginosa clinical strains forming different biofilm types. Several amino acid sequences were obtained from the partially purified antibiofilm protein, named alterocin. The Pseudoalteromonas sp. 3J6 genome was sequenced and a candidate alt gene was identified by comparing the genome-encoded proteins to the sequences from purified alterocin. Expressing the alt gene in another non-active Pseudoalteromonas sp. strain, 3J3, demonstrated that it is responsible for the antibiofilm activity. Alterocin is a 139-residue protein including a predicted 20-residue...

AltiKa: a Ka-band altimetry payload and system for operational altimetry during the GMES period
Provedor de dados: 5
Autores: Vincent, Patrick; Steunou, N; Caubet, E; Phalippou, L; Rey, L; Thouvenot, E; Verron, J.
This paper describes the Ka-band altimetry payload and system that has been studied for several years by CNES, ALCATEL SPACE and some science laboratories. Altimetry is one of the major elements of the ocean observing system to be made sustainable through the GEOSS ( Global Earth Observation System of Systems) and GMES ( Global Monitoring of the Environment and Security) programs. A short review of some mission objectives to be fulfilled in terms of mesoscale oceanography in the frame of the GEOSS and GMES programs is performed. To answer the corresponding requirements, the approach consisting in a constellation of nadir altimeter is discussed. A coupled Ka-band altimeter-radiometer payload is then described; technical items are detailed to explain how...

Altimeter dual-frequency observations of surface winds, waves, and rain rate in tropical cyclone Isabel - art. no. C01004,
Provedor de dados: 5
Autores: Quilfen, Yves; Tournadre, Jean; Chapron, Bertrand.
[1] Extreme weather events such as tropical cyclones are difficult to observe with conventional means. Satellite-based observations provide essential measurements of key parameters governing tropical cyclones. They are critical for short-term forecasting. Radiometers onboard the Defense Meteorological Satellite Program satellite series, WindSat and Tropical Rainfall Measuring Mission satellites, scatterometers onboard the ERS, ADEOS, and QuikScat satellites offer unprecedented synoptic observations of surface wind and atmospheric liquid water content, revealing the storm structures with good accuracy. However, satellite estimates do not provide direct measurements of geophysical parameters and can suffer from limitations linked to the sensors...

Altimeter estimation of sea surface wind stress for light to moderate winds
Provedor de dados: 5
Autores: Vandemark, Douglas; Edson, James B; Chapron, Bertrand.
Aircraft altimeter and in situ measurements are used to examine relationships between altimeter backscatter and the magnitude of near-surface wind and friction velocities. Comparison of altimeter radar cross section with wind speed is made through the modified Chelton-Wentz algorithm. Improved agreement is found after correcting 10-m winds for both surface current and atmospheric stability. An altimeter friction velocity algorithm is derived based on the wind speed model and an open-ocean drag coefficient. Close agreement between altimeter- and in situ-derived friction velocities is found. For this dataset, quality of the altimeter inversion to surface friction velocity is comparable to that for adjusted winds and clearly better than the inversion to true...

Altimeter sea state bias: A new look at global range error estimates
Provedor de dados: 5
Autores: Chapron, Bertrand; Vandemark, D; Elfouhaily, T; Thompson, Dr; Gaspar, P; Labroue, S.
A nonparametric SSB model, derived using the TOPEX altimeter, is analyzed to show a new decomposition of the form SSB = bH(s) + f(sigma (o)), where b is 0.03 and the function of radar cross section (sigma (o)) is an absolute second-order range correction residing outside the conventional nondimensional SSB model. Expected variability in the dominant bH(s) term and its ties to the long wave orbital velocity and shorter-scale slope variances are discussed using a physic ally-motivated restatement of recent EM bias theory. The geometry of steep near-breaking waves, neglected within current theory, is invoked as one plausible explanation for the observed H-s-independent SSB component.

Altimetry and models in the tropical oceans - a review
Provedor de dados: 5
Autores: Arnault, S; Perigaud, C.
Tropical oceans play a key role in climatic variations. Ocean-atmosphere interactions induce large-scale and low-frequency variations which, due to the specificity of tropical ocean dynamics, are very difficult to observe with traditional in situ measurements. During the past twenty years, a variety of numerical models of diverse complexity have contributed much to the description, understanding and prediction of ocean variability in the tropics. However, the capacity of these models to simulate adequately the ocean variability heavily depends on the accuracy of the atmospheric forcings and that of initial conditions. Satellite altimetry provides a unique opportunity to avoid the problem of scarce and non-synoptic in situ data coverage for the large-scale...

Altimetry combined with hydrography for ocean transport estimation
Provedor de dados: 5
Autores: Gourcuff, Claire; Lherminier, Pascale; Mercier, Herle; Le Traon, Pierre-yves.
A method to estimate mass and heat transports across hydrographic sections using hydrography together with altimetry data in a geostrophic box inverse model is presented. Absolute surface velocities computed from AVISO altimetry products made up of a combination of sea surface height measurements and geoid estimate are first compared to Ship Acoustic Doppler Current Profiler (S-ADCP) measurements of the Ovide project along hydrographic sections repeated every 2 years in summer from Portugal to Greenland. The rms difference between S-ADCP and altimetry velocities averaged on distances of about a hundred km accounts to 3.3 cm s−1. Considering that the uncertainty of S-ADCP velocities is found at 1.5 cm s−1, altimetry errors are estimated at 3 cm s−1....

In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and...

Altimetry-Based Diagnosis of Deep-Reaching Sub-Mesoscale Ocean Fronts
Provedor de dados: 5
Autores: Siegelman, Lia; Klein, Patrice; Thompson, Andrew F.; Torres, Hector S.; Menemenlis, Dimitris.
Recent studies demonstrate that energetic sub-mesoscale fronts (10–50 km width) extend in the ocean interior, driving large vertical velocities and associated fluxes. However, diagnosing the dynamics of these deep-reaching fronts from in situ observations remains challenging because of the lack of information on the 3-D structure of the horizontal velocity. Here, a realistic numerical simulation in the Antarctic Circumpolar Current (ACC) is used to study the dynamics of submesocale fronts in relation to velocity gradients, responsible for the formation of these fronts. Results highlight that the stirring properties of the flow at depth, which are related to the velocity gradients, can be inferred from finite-size Lyapunov exponent (FSLE) at the surface....

The distribution of dissolved aluminium (dAl) in the water column of the North Atlantic and Labrador Sea was studied along GEOTRACES section GA01 to unravel the sources and sinks of this element. Surface water dAl concentrations were low (median of 2.5 nM) due to low aerosol deposition and removal by phytoplankton. However, surface water dAl concentrations were enhanced on the Iberian and Greenland shelves (up to 30.9 nM) due to continental inputs (rivers, glacial flour and ice melt). A negative correlation was observed between dAl in surface waters and primary production, phytoplankton community structure and biogenic opal production. The abundance of diatoms exerted a significant (p &lt; 0.01) control on the surface particulate Al (pAl) to dAl ratios by...

Amazon River propagation evidenced by a CO2 decrease at 8°N, 38°W in September 2013
Provedor de dados: 5
Autores: Lefèvre, Nathalie; Tyaquiçã, Pedro; Veleda, Doris; Perruche, Coralie; Van Gennip, Simon Jan.
The surface fugacity of CO2 (fCO2) has been measured hourly at a mooring at 8°N, 38°W, using a spectrophotometric CO2 sensor, from June to October 2013. In September 2013, the fCO2 and the sea surface salinity (SSS) decrease significantly. The high precipitation due to the presence of the Intertropical Convergence Zone (ITCZ) and the propagation of low salinity waters from the Amazon River plume explain the decrease of SSS. Indeed, in fall, the retroflection of the North Brazil Current (NBC) feeds the North Equatorial Counter Current (NECC) and transports Amazon waters to the eastern part of the tropical Atlantic. Simulations from a three dimensional physical and biogeochemical model and observations at the mooring show that the Amazon plume reached the...

Amazonian former gold mined soils as a source of methylmercury: Evidence from a small scale watershed in French Guiana
Provedor de dados: 5
Autores: Guedron, Stephane; Grimaldi, Michel; Grimaldi, Catherine; Cossa, Daniel; Tisserand, Delphine; Charlet, Laurent.
Total mercury (HgT) and monomethylmercury (MMHg) were investigated in a tropical head watershed (1 km(2)) of French Guiana. The watershed includes a pristine area on the hill slopes and a former gold mined flat in the bottomland. Concentrations of dissolved and particulate HgT and MMHg were measured in rain, throughfall, soil water and at three points along the stream. Samples were taken in-between and during 14 storm events at the beginning and middle of the 2005 and 2006 rainy seasons. Dissolved and particulate HgT concentrations in the stream slightly increased downstream, while dissolved and particulate MMHg concentrations were low at the pristine sub-watershed outlet (median = 0.006 ng L-1 and 1.84 ng g(-1), respectively) and sharply increased at the...

Ambient flow velocity and resulting clearance rates of the terebellid polychaete Lanice conchilega (Pallas, 1766)
Provedor de dados: 5
Autores: Denis, L; Desroy, Nicolas; Ropert, Michel.
A laboratory flume study was conducted to determine the effect of flow velocity on clearance rates of the Polychaeta Terebellidea Lanice conchilega (Pallas, 1966). Using sets of 75 individuals collected along the east coast of the English Channel, we measured clearance rates at five flow velocities of approximate to 4, 9, 15, 22 and 27 cm s(-1) with a culture of the diatom Chaetoceros calcitrans as food source. During each control (without polychaetes) or clearance (with Lanice conchilega) experiment, in vivo fluorescence was continuously monitored. Further HPLC analysis confirmed the sediment resuspension for the highest flow velocities tested, indicating the need for 'corrections' from control experiments. The global pattern resulted in a dome-shaped...

Ambient levels and occurence of persistent organic pollutans (POPs) in the airshed of a mediterranean coastal lagoon
Provedor de dados: 5
Autores: Castro-jimenez, Javier; Mariani, G.; Vives, I.; Skejo, A.; Umlauf, G.; Zaldivar, Jose-manuel; Messiaen, Gregory; Laugier, Thierry.
Persistent organic pollutants (POPs) present in the airshed of a given environment may participate in exchange / deposition processes that will determine their inputs to the terrestrial or aquatic ecosystems. In addition, physico-chemical properties of POPs may favour long range atmospheric transport to other areas, even reaching remote zones. It is therefore important to determine the airshed POPs concentration in order to evaluate the potential amounts that may participate in the mentioned processes. Coastal lagoons are characterized by a high biodiversity and intense primary production leading to both ecological and economical considerable importance. Thau lagoon seems to be under intense anthropogenic pressure (urban, industrial, agricultural and shell...

Ambient noise Rayleigh wave tomography across the Madagascar island
Provedor de dados: 5
Autores: Adimah, N I; Padhy, S.
The unusual complex lithospheric structure of Madagascar is a product of a number of important geological events, including: the Pan-African Orogeny, episodes of Late Cenozoic intraplate volcanism and several phases of deformation and metamorphism. Despite this rich history, its detailed crustal structure remains largely underexplored. Here, we take advantage of the recently obtained data set of the RHUM-RUM (Réunion Hotspot and Upper Mantle–Réunions Unterer Mantel) seismological experiment, in addition to previously available data sets to generate the first Rayleigh wave group velocity maps across the entire island at periods between 5 and 30 s using the ambient noise tomography technique. Prior to preliminary data preparation, data from Ocean Bottom...

L’analyse des activités de fileyage (nombre de navires, répartition géographique, métiers pratiqués) dans le golfe de Gascogne entre 2013 et 2019 montre une grande stabilité de ces activités dans leur diversité. Les informations sur les caractéristiques des engins de pêche et leur évolution sont encore trop parcellaires pour qu’une conclusion puisse être tirée. L’analyse devrait également être approfondie pour d’autres engins, et notamment ceux mis en oeuvre par les navires étrangers.

Autores: Deslous-paoli, Jean-marc; Zanette, Yvan; Heral, Maurice; Masse, Henri; Garnier, Jacqueline.
The breeding of Pacific oysters Crassostra gigas, in non tidal ponds, before commercialization, brings about an improvement of the shell and of the quantity and quality of the tissues. In fact, the Berthome's indice (1978) moves from 1.36 in June to 0.68 December, and the density of the shell increases in the same time from 1.79 to 1.98. On the other hand, the percentage of tissues in the oyster is 12.4% at the end of gametogenesis and more than 9% at the end of breeding. The dry tissues are composed of 10.3 of ash, 40.3% of proteins, 12.6% of lipids and 9% of carbohydrate. 95% of the carbohydrate are glycogen. The resulting energetic values are measured to 5.10 cal-mg super(-1) of dry tissues ash free.

Autores: Hildebrand, M.
The material properties of over 50 different laminates made by a group of Finnish boat-yards have been measured in a large test project. Tension, compression, bending, interlaminar shear and impact tests have been carried out for all the laminates. Among others, different polyester resins, different woven and non-woven fabrics, chopped strand mat and unidirectional roving were used as basic ply materials. The effect of various parameters has been determined not only on the maximum failure strength, but also on the strain level at which the first failure occurs. Main differences between the ratio of static and impact test results of the different materials have been determined. The results show that by choosing certain material parameters efficiently,...

Amélioration de l'évaluation des stocks de mollusques cultivés en Charente- Maritime

Autores: Bacher, Cedric; Deslous-paoli, Jean-marc; Heral, Maurice; Prou, Jean.
The expansion of shellfish culture businesses (oysters, mussels, clams...) gives way to a competition for the use of limited food resources, especially in the Marennes-Oléron basin where water circulation is slow. Increasing the amount of cultivated molluscs leads, from a biological point of view, to:- a drop in growth performances- a rise in chronic mortalities, higher and higher, due to a weakness in the physiological state with a lack of stocks which would have compensated the habitat seasonal shortages (end of winter, etc...)- a greater weakness to diseases, linked to a deficient physiological state and a density rise which increases the proximity rate and thus, parasite propagation speed.For these primary reasons, and for the future of oyster culture,...

Consequently, we assessed themost commonly used species to establish their growth and size profiles, their cytomorphological, biochemical, biomolecular identification as well as their cytometer signs, and also their ability to grow under extreme conditions of temperature and salinity. This work aimed at matching the conformity of the strains used in Argenton (dispatched to most of the French commercial hatcheries) to those of a referenced culture collection. A previous screening preceded this study, because of the 45 species and/or clones held originally, Argenton kept no more than 15 species. As most of the latter are also represented in referenced collection, our strains are therefore correctly identified. On the other hand, the...

Elle a montré la nécessité d'un meilleur contrôle du cheptel depuis l'ensemencement jusqu'à la commercialisation afin de pouvoir atteindre de manière fiable des rendements de l'ordre de 2,5 T/ha/an.

Le programme d'amélioration des techniques d'élevage de la Chevrette Macrobrachium rosenbergii en Guyane constitue la deuxième phase du programme d'expérimentation mené sur la station IFREMER de Kourou. Jusqu'en 1988, l'effort a porté sur l'analyse du système continu classique utilisé par l'ensemble des producteurs de Macrobrachium aux Antilles et en Guyane. A partir de 1988, il apparut que la résolution des problèmes posés par son application passait par l'utilisation de schémas de gestion de la population en mode discontinu. Les expérimentations ont donc porté sur les principales conditions d'élevage susceptibles d'améliorer l'efficacité du schéma d'exploitation de la population. En prégrossissement, il s'agissait d'obtenir le meilleur compromis...

Amélioration du protocole de PCR quantitative pour la détection de l'OsHV1 chez l'huître creuse, Crassostrea gigas, dans le cadre du projet TRIPLOFIMER et suivi d'individus lors du phénomène de mortalité estivale dans le cadre du projet AQUAFIRST
Provedor de dados: 5
Autores: Riou, Antoine.
Depuis 1991, des épisodes de mortalités massives touchent les élevages ostréicoles français, notamment pour l'espèce Crassostrea gigas. Un des facteurs responsables de ces événements est le virus de l'Herpès de l'huître : Oyster Herpesvirus type 1 ou OsHV-1. Les travaux réalisés au cours de ce stage ont contribué dans un premier temps à l'amélioration du protocole d'analyse basé sur l'utilisation d'un appareil de Polymerase Chain Reaction (PCR) en temps résel, puis aux analyses et au suivi de la charge virale par cette technique, d'individus entrant dans le cadre des projets - TRIPLOMER et AQUAFIRST-UE. Cette approche permettra par la suite de réaliser des diganostics fiables de la maladie tout en précisant le nombre de copies ADN (Acide...

World fish farm production is growing rapidly. However, the supply of fishmeal and fish oil, the major ingredients of fish diets, has reached a limit because of the limits in the exploitation of wild fish stocks that cannot be increased to meet a growing demand. The main response, especially in Europe, has been the progressive replacement of fishmeal and fish oil by plant products. However, the strong reduction of growth and sometimes survival of fish fed highly substituted diets has urged research on the genetic potential for adaptation to plant-based diets. Recent results clearly demonstrate that fish can be selected for their capacity to grow when fed plant-based diets, even though the underlying mechanisms remain unknown. Genotype-diet interactions...

The New-Caledonian shrimp industry is based on the controlled reproduction of the shrimp Litopenaeus stylirostris, a species which was introduced in the 80s. The major difficulty to which the industry has been faced for 10 years is the occurrence of the "syndrome 93", which corresponds to mortality phases when the temperature falls down in April-May-June. This mortality is associated to the pathogenic bacteria Vibrio penaecida and is expressed at different levels which are variable from year ta year and from pond to pond. No resistance to this pathology has been developed spontaneously. This is likely due to the protocole used to rear spawners, which does not allow to implement an efficient selective pressure at each generation  An experimental selection...

Amélioration génétique pour la résistance au Syndrome 93 : bilan de 5 générations de sélection expérimentale

Selective breeding of shrimp for viral resistance is established for species like L. vannamei and L. stylirostris. However, selection for bacterial infection resistance is not documented. In New Caledonia, "Syndrome 93" is a vibriosis that affects cultured shrimps during the cool season with survival from 15 to 30%. Current practises for breeders rearing at low densities do not improve the resistance of the offsprings mainly because selection pressures for "Syndrome 93" are low. Even after the fifth generation, survival improvement is not significant.

The issue of the presentation of fresh fish to the consumer is far from being solved despite the numerous works which tackled this question. Too often, fishes sold away from the coast are not appetizing and numerous fish lovers prefer not to eat them, in the absence of very fresh fish. Indeed, many difficulties occur when it comes to shipping the dozens of thousands of tonnes of fish caught every year by industrial fishing boats to places located hundreds of kilometres away from the ocean.

Generally, fisheries in developed countries have to face three main constraints (according to the report of the synthesis meeting of September 17th, 1982, ISTPM Technical Reports n° 3 a 1983):- The evolution of marine legislation has just limited their access to a number of areas, forcing them to focus on their own economic area.- The high exploitation level of a number of stocks raises the issue of the limits of their production capacities.- Exploitation costs have strongly increased because of the oil crisis. As regards to this situation, the general concept of resource management, that is to say the passing of a set of measures aiming to protect and keep a good balance of the exploited stocks taking into account the laws of marine ecology and population...

Today, the seaweed industry's main products are the alginates and carraghenanes. The industrial network faces many problems. However, it remains prosperous since it ranks fifth in the world for alginate production and third for caraghenanes'. This stability which seems safe on a middle term standpoint must not conceal the crisis which previously hit Fucus' exploitation. Rightly so, being harvested until approximately 1950 for soil amendment purposes, coastal kelp (i.e. Fucus), was replaced by chemical fertilizers. Brittany's production which was reaching 180 000 cubic metre in the twenties, close to 200 000 tons of fresh kelp, would have become non existent if it had not been converted into seaweed meal for livestock feed. The market demand was then...

Fishing regulations in waters under the responsibility of the EEC mainly concern three techniques of site development:  - catch quotas by species and by area (TAC, a word adapted from the English Total Allowable Catch); - the definition – of the technical characteristics of the fishing devices used (meshing, type of trawl,...); - setting a minimum commercial size for each species.  The regulations of meshing and other constraints relating to the technical characteristics of the fishing devices aim to modify the composition of the catches by age class.  The TACs are a technique for controlling the level of exploitation of the stocks. Controlling the fishing effort that they generate is carried out indirectly in the short or mid term.

Les changements intervenus dans les pêches lagunaires de Côte d'Ivoire au cours des vingt dernières années ont Crée de nombreux problèmes. Ces changements ont souvent pris la forme d'une introduction de nouveaux engins de pêche plus efficaces. Cela a non seulement entrai-né un accroissement considérable de l'effort de pêche et une certaine surexploitation des stocks, mais est aussi devenue  une source nouvelle de conflits entre les pêcheurs continuant à employer les engins traditionnels et ceux utilisant les nouveaux engins. A la demande du Gouvernement, une mission FAO s'est rendue en Côte-d'Ivoire en mars-avril 1985 afin de préparer un plan d'aménagement des pêcheries lagunaires. A cette fin, la mission a procédé à une évaluation bio-économique de l'état...

Autores: Le Fevre-lehoerff, G; Woehrling, Daniel.
Studies have been conducted at Gravelines (France) to estimate the effects of construction and then, the operation of a nuclear power plant. These studies take into account diverse sources of stress: the thermal impact ( Delta T = +11 degree C), the chlorination procedures (0.8 ppm) and the mechanical effects (flow rate 240 m super(3)/s). Distinction has been made between impacts occurring within the cooling system and impacts within the thermal plume. The ecological monitoring has been particularly concerned with water, sediment and organic matter, benthic and pelagic organisms. Results of these field studies include a baseline information in terms of physical, chemical and biological measurements and describe a "reference state" with chronological series.

Amino-acids in the sediments and interstitial waters from odp hole-677b and hole-678b in the panama basin
Provedor de dados: 5
Autores: Kawahata, H; Ishizuka, T.
Biogenic siliceous and calcareous sediments were drilled at sites 677 and 678 on the flank of Costa Rica Rift in the Panama basin. We analysed DCAA (dissolved combined amino acids) and DFAA (dissolved free amino acids) in the interstitial waters as well as THAA (total hydrolyzable amino acids) in the sediments in order to evaluate the relationship between THAA, DCAA and DFAA. Comparison of the THAA in the sediments and in marine settling particulate matter (Ittekkot et al., 1984 b) showed that the concentration of non-protein amino acids (e. g., beta-alanine, gamma-aminobutyric acid, and ornithine) was much higher in the sediments and that the neutral amino acid fraction was depleted in the sediments. These results, together with the organic carbon...

Ce rapport présente les résultats du suivi cartographique et géo­morphologique de la pollution des côtes bretonnes par le pétrole de l'AMOCO CADIZ jusqu'au mois de Mars 1979, c'est-à-dire un an après la catastrophe.  Les reconnaissances aériennes associées à des visites détaillées des 160 stations établies entre la pointe ST MATHIEU et le sillon du TALBERT ont permis de suivre l'arrivée du pétrole à la côte puis sa disparition plus ou moins rapide. Pour dresser ce bilan, plus d'une vingtaine de vols ont été effectués ainsi que 5 campagnes de terrain ; débutés immédiatement après le naufrage de l'AMOCO CADIZ en collaboration avec de nombreux organismes, ces travaux se sont poursuivis à partir de Novembre 1978 dans le cadre du program­me de suivi écologique...

AMP-deaminase in elasmobranch fish: A comparative histochemical and enzymatic study
Provedor de dados: 5
Autores: Thebault, Marie-t; Izem, Lahoucine; Leroy, Jean Paul; Gobin, Eric; Charrier, Gregory; Raffin, Jean-paul.
AMP-deaminase activity was measured in white muscle from a wide range of fish, including one cyclostome, 13 chondrosteans, and one teleost to elucidate the pattern of the AMP-deaminase activity in white muscle of fish. Compared to a mammalian (rat) muscle extract, low enzyme activities are found in the cyclostome and two elasmobranchs from two families (Scyliorhinidae, Hexanchidae). In contrast, higher AMP-deaminase activities, similar to mammals, are expressed in Squalidae, all families of skates, Chimaeridae and in the teleostean fish. We then compared AMP-deaminase activities in red and white muscles from two representative elasmobranch fish, the dogfish (Scyliorhinus canicula) and the thornback ray (Raja clavata). The fibre type composition and...

Amphi-Atlantic cold-seep Bathymodiolus species complexes across the equatorial belt
Provedor de dados: 5
Autores: Olu, Karine; Von Cosel, R; Hourdez, S; Carney, S; Jollivet, D.
Deep-sea bivalves of the subfamily Bathymodiolinae (family Mytilidae) are very widespread and form dense beds in reduced environments such as hydrothermal vents and cold seeps. Bathymodiolus mussels recently discovered on African cold seeps strangely resemble Gulf of Mexico and Barbados seep species. This raises intriguing questions regarding their taxonomic relationships and their dispersal capabilities across the Atlantic equatorial belt. The morphological study of the shell and soft parts of mussels from either sites of the Atlantic shows that they form two distinct groups: the Bathymodiolus boomerang group (also including Bathymodiolus heckerae and a species from Africa), and the Bathymodiolus childressi group (also including Bathymodiolus mauritanicus...

Amplification of environmental fluctuations by marine ecosystems
Provedor de dados: 5
Autores: Silvert, W.
Environmental variability is an important cause of fluctuations in marine ecosystems. Some ecosystems appear to have characteristic resonant frequencies, and even a weak environmental signal at one of these frequencies can cause large changes in population sizes. It is already known that some commercial fish stocks undergo abundance cycles which can be explained in this way, since models of their population dynamics exhibit resonances at or near the appropriate frequencies. In this paper it is shown that resonance found in Lotka-Volterra models of predator-prey systems appears to be a likely cause of many of the fluctuations found in marine ecosystems.

Amylase et trypsine du zooplancton et surveillance du milieu pelagique en Bretagne
Provedor de dados: 5
Autores: Samain, J F; Moal, J; Le Coz, Jr; Daniel, J Y.
As the composition and physiological activity of zooplankton is mostly controlled by environmental conditions, their measurement in situ may be a suitable tool for monitoring the pelagic system. The digestive enzymes, amylase and trypsin, of the zooplankton of coastal waters of Brittany, have been measured during three years as their levels are related to taxonomic composition and feeding patterns of zooplankton. There is evidence of a well-defined annual cycle of these enzymes related to changes in taxonomic composition and feeding patterns with different characterized phases. Observed variability is analysed and associated with the diversity, the stability and the difference in maturity of ecological conditions in the area.

Amylase polymorphism affects growth in the cupped oyster Crassostrea gigas
Provedor de dados: 5
Autores: Huvet, Arnaud; Samain, Jean-francois; Boudry, Pierre; Bedier, Edouard; Ropert, Michel; Van Wormhoudt, A.
The better understanding of physiological and environmental factors that determine optimal food conversion efficiencies is of major interest for the cupped oyster Crassostrea gigas for which the strong increase of aquaculture has been correlated in France with a decrease in productivity due to competition between aquatic species for limited food supplies at grow-out sites. To investigate the non-neutrality of the polymorphism of amylase, a key enzyme for carbohydrate assimilation, in oyster physiology, we report in the present paper the growth and survival measurement of amylase genotypes within five bi-parental C. gigas families, bred to be polymorph at the two PCR-RFLP amylase markers, and reared over one year under standard culture conditions in two...

Autores: Lossouarn, Julien; Dupont, Samuel; Gorlas, Aurore; Mercier, Coraline; Bienvenu, Nadege; Marguet, Evelyne; Forterre, Patrick; Geslin, Claire.
Mobile genetic elements (MGEs) such as viruses, plasmids, vesicles, gene transfer agents (GTAs), transposons and transpovirions, which collectively represent the mobilome, interact with cellular organisms from all three domains of life, including those thriving in the most extreme environments. While efforts have been made to better understand deep-sea vent microbial ecology, our knowledge of the mobilome associated with prokaryotes inhabiting deep-sea hydrothermal vents remains limited. Here we focus on the abyssal mobilome by reviewing accumulating data on viruses, plasmids and vesicles associated with thermophilic and hyperthermophilic Bacteria and Archaea present in deep-sea hydrothermal vents.

An accurate formula to calculate exclusion power of marker sets in parentage assignment
Provedor de dados: 5
Autores: Vandeputte, Marc.
In studies on parentage assignment with both parents unknown, the exclusion power of a marker set is generally computed under the hypothesis that the potential families tested are independent and unrelated samples. This tends to produce overly optimistic exclusion power estimates. In this work, we have developed a new formula that gives almost unbiased results at the population level.

An adaptable toolkit to assess commercial fishery costs and benefits related to marine protected area network design
Provedor de dados: 5
Autores: Daigle, Rémi M.; Monaco, Cristian; Elgin, Ashley K.
Around the world, governments are establishing Marine Protected Area (MPA) networks to meet their commitments to the United Nations Convention on Biological Diversity. MPAs are often used in an effort to conserve biodiversity and manage fisheries stocks. However, their efficacy and effect on fisheries yields remain unclear. We conducted a case-study on the economic impact of different MPA network design strategies on the Atlantic cod (Gadus morhua) fisheries in Canada. The open-source R package that we developed to analyze this case study can be customized to conduct similar analyses for other systems. We used a spatially-explicit individual-based model of population growth and dispersal coupled with a fisheries management and harvesting component. We...

An Advanced Algorithm to Retrieve Total Atmospheric Water Vapor Content From the Advanced Microwave Scanning Radiometer Data Over Sea Ice and Sea Water Surfaces in the Arctic

Autores: Zabolotskikh, Elizaveta, V; Khvorostovsky, Kirill S.; Chapron, Bertrand.
An advanced algorithm for atmospheric water vapor column (WVC) retrieval from the Advanced Microwave Scanning Radiometer (AMSR) measurements over the Arctic sea ice (SI) and open ocean waters is presented. The algorithm is built on the physical modeling of the brightness temperature (BT) of the microwave radiation of the SI-open ocean-atmosphere system at the AMSR frequencies and polarizations. The BTs are calculated using a data set of the SI, atmospheric, and oceanic parameters changing in the range of their natural variability in the Arctic, and using the SI microwave emission coefficients varied according to the published experimental data. The inverse operator explores neural networks (NNs), trained on an ensemble of modeled BTs. The algorithm is...

An alternative early opening scenario for the Central Atlantic Ocean
Provedor de dados: 5
Autores: Labails, Cinthia; Olivet, Jean-louis; Aslanian, Daniel; Roest, Walter.
The opening of the Central Atlantic Ocean basin that separated North America from northwest Africa is well documented and assumed to have started during the Late Jurassic. However, the early evolution and the initial breakup history of Pangaea are still debated: most of the existing models are based on one or multiple ridge jumps at the Middle Jurassic leaving the oldest crust on the American side, between the East Coast Magnetic Anomaly (ECMA) and the Blake Spur Magnetic Anomaly (BSMA). According to these hypotheses, the BSMA represents the limit of the initial basin and the footprint subsequent to the ridge jump. Consequently, the evolution of the northwest African margin is widely different from the northeast American margin. However, this setting is in...

An Alternative to Static Climatologies: Robust Estimation of Open Ocean CO2 Variables and Nutrient Concentrations From T, S, and O-2 Data Using Bayesian Neural Networks
Provedor de dados: 5
Autores: Bittig, Henry C.; Steinhoff, Tobias; Claustre, Harve; Fiedler, Bjoern; Williams, Nancy L.; Sauzede, Raphaelle; Koertzinger, Arne; Gattuso, Jean-pierre.
This work presents two new methods to estimate oceanic alkalinity (A(T)), dissolved inorganic carbon (C-T), pH, and pCO(2) from temperature, salinity, oxygen, and geolocation data. "CANYON-B" is a Bayesian neural network mapping that accurately reproduces GLODAPv2 bottle data and the biogeochemical relations contained therein. "CONTENT" combines and refines the four carbonate system variables to be consistent with carbonate chemistry. Both methods come with a robust uncertainty estimate that incorporates information from the local conditions. They are validated against independent GO-SHIP bottle and sensor data, and compare favorably to other state-of-the-art mapping methods. As "dynamic climatologies" they show comparable performance to classical...

A detailed study, based on ocean‐bottom seismometers (OBSs) recordings from two recording periods (3.5 months in 2011 and 2 months in 2014) and on a high‐resolution, 3D velocity model, is presented here, which provides an alternative view of the microseismicity along the submerged section of the North Anatolian fault (NAF) within the western Sea of Marmara (SoM). The nonlinear probabilistic software packages of NonLinLoc and NLDiffLoc were used for locating earthquakes. Only earthquakes that comply with the following location criteria (e.g., representing 20% of the total amount of events) were considered for analysis: (1) number of stations≥5; (2) number of phases≥6, including both P and S; (3) root mean square (rms) location error≤0.5  s; and...

An altimetry-based gravest empirical mode south of Africa: 1. Development and validation
Provedor de dados: 5
Autores: Swart, Sebastiaan; Speich, Sabrina; Ansorge, Isabelle J.; Lutjeharms, Johann.
Hydrographic transects of the Antarctic Circumpolar Current (ACC) south of Africa are projected into baroclinic stream function space parameterized by pressure and dynamic height. This produces a two-dimensional gravest empirical mode (GEM) that captures more than 97% of the total density and temperature variance in the ACC domain. Weekly maps of absolute dynamic topography data, derived from satellite altimetry, are combined with the GEM to obtain a 16 year time series of temperature and salinity fields. The time series of thermohaline fields are compared with independent in situ observations. The residuals decrease sharply below the thermocline and through the entire water column the mean root-mean-square (RMS) error is 0.15 degrees C, 0.02, and 0.02 kg...

An altimetry-based gravest empirical mode south of Africa: 2. Dynamic nature of the Antarctic Circumpolar Current fronts
Provedor de dados: 5
Autores: Swart, Sebastiaan; Speich, Sabrina.
Swart et al. (2010) applied altimetry data to the gravest empirical mode south of Africa to yield a 16 year time series of temperature and salinity sections. In this study we use these thermohaline sections to derive weekly estimates of heat content (HC) and salt content (SC) at the GoodHope meridional transect of the Antarctic Circumpolar Current (ACC). These estimates compare favorably to observed data. The resulting 16 year time series of HC and SC estimates are used to explain the subsurface thermohaline variability at each ACC front and frontal zone. The variability at the Subantarctic Zone (SAZ) is principally driven by the presence of Agulhas Rings, which occur in this region approximately 2.7 times per annum and are responsible for the longest and...

This study investigated the non-neutrality of genetic polymorphism in two alpha-amylase genes (AMYA and AMYB) in the oyster Crassostrea gigas. Bi-parental oyster families, bred to be polymorphic for markers in these genes, were monitored for growth and survival for 1 year under standard culture conditions in two French production sites. Within-family genotype frequencies indicated that the two amylase genes were closely linked (c. 1.7 cM). Within two of three families, significant differences in growth were observed between genotypes at one of the two production sites, suggesting that this polymorphism is not neutral and might be under selection because of its role in digestive function. Estimated daily yields were different between amylase genotypes,...

An analysis of the tidal signal in the WOCE sea level dataset
Provedor de dados: 5
Autores: Ponchaut, F; Lyard, F; Le Prevost, C.
A new sea level observation network initiated by the World Ocean Circulation Experiment (WOCE) program is delivering hourly data from about 150 ocean stations worldwide. A complete analysis of these data was performed using a least squares method allowing better accuracy over time series virtually unlimited in time (up to 13 yr in this case). In addition to the classical tidal harmonic constants, the power density spectrum of the detided signal was computed. The 95% confidence intervals of the results of the analysis have been systematically estimated. The numerical and statistical methods applied to produce these numbers are presented for three stations as an illustration. One example of application of this new dataset and its error bars is the selection...

An analytical study of the atmospheric boundary layer flow and divergence over a SST front
Provedor de dados: 5
Autores: Ayet, Alex; Redelsperger, Jean-luc.
We present an analytical model reproducing literature‐based numerical simulations of the Marine Atmospheric Boundary Layer (MABL) over a SST front, with wind blowing from the cold to the warm side. Turbulence is parameterised through a varying diffusion coefficient with two critical features: it is parabolic on the vertical and its mean value is decoupled from the MABL height (unlike an Ekman layer model). These two novel features are found essential to recover the internal structure of the MABL from numerical simulations. Different dynamical regimes are obtained and interpreted in terms of non‐dimensional numbers characterising the relative importance of terms driving the momentum equation. A closed‐form expression of the vertically integrated wind...

An Annual Cycle of Submesoscale Vertical Flow and Restratification in the Upper Ocean
Provedor de dados: 5
Autores: Yu, Xiaolong; Naveira Garabato, Alberto C.; Martin, Adrian P; Buckingham, Christian; Brannigan, Liam; Su, Zhan.
Numerical simulations suggest that submesoscale turbulence may transform lateral buoyancy gradients into vertical stratification, and thus restratify the upper ocean via vertical flow. However, the observational evidence for this restratifying process has been lacking due to the difficulty in measuring such ephemeral phenomena, particularly over periods of months to years. This study presents an annual cycle of the vertical velocity and associated restratification estimated from two nested clusters of meso- and submesoscale-resolving moorings, deployed in a typical mid-ocean area of the Northeast Atlantic. Vertical velocities inferred using the non-diffusive density equation are substantially stronger at submesoscales (horizontal scales of 1-10 km) than at...

An approach to co-construct sustainable development indicators in aquaculture
Provedor de dados: 5
Autores: Rey-valette, Helene; Clement, O; Aubin, Joel; Mathe, Syndhia; Chia, Eduardo; Legendre, Marc; Caruso, D; Mikolasek, Olivier; Blancheton, Jean-paul; Slembrouck, J; Baruthio, Aurele; Rene, Francois; Levang, Patrice; Morissens, Pierre; Lazard, Jerome.
It cannot be said that aquaculture has ignored sustainable development (SD), judging by the number of standards, guides and indicators devoted to it, produced mainly under the aegis of international organizations such as FAO, The European Union and sorne NGOs. However, these continue to be perceived in large measure as constraints rather than as shared objectives by actors. Faced with this situation, which is not specific to aquaculture but on the contrary quite general regardless of sector, context or scale, the authors seek to propose a generic approach that through a collective process, i.e. a co-construction, promotes the implementation and appropriation of SD. What makes this approach original is not only the participatory nature of the construction,...

The abyssal seafloor covers more than 50% of planet Earth and is a large reservoir of still mostly undescribed biodiversity. It is increasingly targeted by resource-extraction industries and yet is drastically understudied. In such remote and hard-to-access ecosystems, environmental DNA (eDNA) metabarcoding is a useful and efficient tool for studying biodiversity and implementing environmental impact assessments. Yet, eDNA analysis outcomes may be biased toward describing past rather than present communities as sediments contain both contemporary and ancient DNA. Using commercially available kits, we investigated the impacts of five molecular processing methods on eDNA metabarcoding biodiversity inventories targeting prokaryotes (16S), unicellular...

The Palomares Margin, an NNE–SSW segment of the South Iberian Margin located between the Alboran and the Algerian–Balearic basins, is dissected by two major submarine canyon systems: the Gata (in the South) and the Alías–Almanzora (in the North). New swath bathymetry, side-scan sonar images, accompanied by 5 kHz and TOPAS subbottom profiles, allow us to recognize these canyons as Mediterranean examples of medium-sized turbidite systems developed in a tectonically active margin.  The Gata Turbidite System is confined between residual basement seamounts and exhibits incised braided channels that feed a discrete deep-sea fan, which points to a dominantly coarse-grained turbiditic system. The Alías–Almanzora Turbidite System, larger and less confined, is a...

The Arctic Ocean simulated in 14 global ocean-sea ice models in the framework of the Coordinated Ocean-ice Reference Experiments, phase II (CORE-II) is analyzed in this study. The focus is on the Arctic liquid freshwater (FW) sources and freshwater content (FWC). The models agree on the interannual variability of liquid FW transport at the gateways where the ocean volume transport determines the FW transport variability. The variation of liquid FWC is induced by both the surface FW flux (associated with sea ice production) and lateral liquid FW transport, which are in phase when averaged on decadal time scales. The liquid FWC shows an increase starting from the mid-1990s, caused by the reduction of both sea ice formation and liquid FW export, with the...

In this paper we compare the simulated Arctic Ocean in 15 global ocean–sea ice models in the framework of the Coordinated Ocean-ice Reference Experiments, phase II (CORE-II). Most of these models are the ocean and sea-ice components of the coupled climate models used in the Coupled Model Intercomparison Project Phase 5 (CMIP5) experiments. We mainly focus on the hydrography of the Arctic interior, the state of Atlantic Water layer and heat and volume transports at the gateways of the Davis Strait, the Bering Strait, the Fram Strait and the Barents Sea Opening. We found that there is a large spread in temperature in the Arctic Ocean between the models, and generally large differences compared to the observed temperature at intermediate depths. Warm bias...

The Atlantic and Arctic Oceans are critical components of the global carbon cycle. Here we quantify the net sea-air CO2 flux, for the first time, across different methodologies for consistent time and space scales for the Atlantic and Arctic basins. We present the long-term mean, seasonal cycle, interannual variability and trends in sea-air CO2 flux for the period 1990 to 2009, and assign an uncertainty to each. We use regional cuts from global observations and modeling products, specifically a pCO(2)-based CO2 flux climatology, flux estimates from the inversion of oceanic and atmospheric data, and results from six ocean biogeochemical models. Additionally, we use basin-wide flux estimates from surface ocean pCO(2) observations based on two distinct...

An Assessment of the Precision and Confidence of Aquatic Eddy Correlation Measurements

The quantification of benthic fluxes with the aquatic eddy correlation (EC) technique is based on simultaneous measurement of the current velocity and a targeted bottom water parameter (e.g., O2, temperature). High-frequency measurements (64 Hz) are performed at a single point above the seafloor using an acoustic Doppler velocimeter (ADV) and a fast-responding sensor. The advantages of aquatic EC technique are that 1) it is noninvasive, 2) it integrates fluxes over a large area, and 3) it accounts for in situ hydrodynamics. The aquatic EC has gained acceptance as a powerful technique; however, an accurate assessment of the errors introduced by the spatial alignment of velocity and water constituent measurements and by their different response times is...

An attempt to evaluate the recent management regulations of the east Atlantic and Mediterranean bluefin tuna stock through a simple simulation model
Provedor de dados: 5
Autores: Fromentin, Jean-marc.
This manuscript proposes a simple simulation model to investigate the implications to the resources of the recent management regulations adopted for the East Atlantic and Mediterranean bluefin tuna stock. If perfectly implemented, the new regulations on minimum size and closed fishing areas mostly lead to a change in the selectivity pattern which moves towards older fish, so decreasing growth-overfishing. The potential sustainable yields therefore considerably increase (almost double in comparison to those that would be obtained without the new regulations) while the SSB can rapidly reach 20% of the virgin SSB. An error of 20% in the implementation of these new regulations affects their efficiencies and does not seem to allow the rebuilding of the SSB at a...

An attribute-diversity approach to functional diversity, functional beta diversity, and related (dis)similarity measures
Provedor de dados: 5
Autores: Chao, Anne; Chiu, Chun-huo; Villéger, Sébastien; Sun, I-fang; Thorn, Simon; Lin, Yi-ching; Chiang, Jyh-min; Sherwin, William B.
Based on the framework of attribute diversity (a generalization of Hill numbers of order q), we develop a class of functional diversity measures sensitive not only to species abundances but also to trait‐based species‐pairwise functional distances. The new method refines and improves on the conventional species‐equivalent approach in three areas: (1) the conventional method often gives similar values (close to unity) to assemblages with contrasting levels of functional diversity; (2) when a distance metric is unbounded, the conventional functional diversity depends on the presence/absence of other assemblages in the study; (3) in partitioning functional gamma diversity into alpha and beta components, the conventional gamma is sometimes less than alpha.

An automated photo-oxidation method for the determination of dissolved organic phosphorus in marine and fresh water
Provedor de dados: 5
Autores: Aminot, Alain; Kerouel, Roger.
A segmented flow automated method with on-line photo-oxidation for the determination of dissolved organic phosphorus + soluble reactive phosphorus (DOP + SRP) in seawater and fresh water is described here. A low-power lamp was used for a compact, easy-to-handle and low-ozone-producing manifold. The influence of seawater matrix components was studied in detail using natural seawater and salt solutions spiked with DOP model compounds. Bromide was found to be the most inhibitory species in seawater. The work shows that most salt solutions referred to as artificial seawater are not satisfactory model matrices to test the actual seawater matrix effect. Since DOP recovered in undiluted seawater samples was about half that obtained in fresh water samples, the...

An Autonomous Approach to Observing the Seasonal Ice Zone in the Western Arctic
Provedor de dados: 5
Autores: Lee, Craig M.; Thomson, Jim.
The Marginal Ice Zone and Arctic Sea State programs examined the processes that govern evolution of the rapidly changing seasonal ice zone in the Beaufort Sea. Autonomous platforms operating from the ice and within the water column collected measurements across the atmosphere-ice-ocean system and provided the persistence to sample continuously through the springtime retreat and autumn advance of sea ice. Autonomous platforms also allowed operational modalities that reduced the field programs’ logistical requirements. Observations indicate that thermodynamics, especially the radiative balances of the ice-albedo feedback, govern the seasonal cycle of sea ice, with the role of surface waves confined to specific events. Continuous sampling from winter into...

An autoregressive model to describe fishing vessel movement and activity
Provedor de dados: 5
Autores: Gloaguen, Pierre; Mahevas, Stephanie; Rivot, Etienne; Woillez, Mathieu; Guitton, Jerome; Vermard, Youen; Etienne, Marie-pierre.
The understanding of the dynamics of fishing vessels is of great interest to characterize the spatial distribution of the fishing effort and to define sustainable fishing strategies. It is also a prerequisite for anticipating changes in fishermen's activity in reaction to management rules, economic context, or evolution of exploited resources. Analyzing the trajectories of individual vessels offers promising perspectives to describe the activity during fishing trips. A hidden Markov model with two behavioral states (steaming and fishing) is developed to infer the sequence of non-observed fishing vessel behavior along the vessel trajectory based on Global Positioning System (GPS) records. Conditionally to the behavior, vessel velocity is modeled with an...

Provedor de dados: 5
Autores: Ailliot, Pierre; Monbet, Valérie; Prevosto, Marc.
In this article, an original Markov-switching autoregressive model is proposed to describe the space-time evolution of wind fields. At first, a non-observable process is introduced in order to model the motion of the meteorological structures. Then, conditionally to this process, the evolution of the wind fields is described using autoregressive models with time-varying coefficients. The proposed model is calibrated and validated on data ill the North Atlantic.

Early Pleistocene glacial cycles in marine O-18 exhibit strong obliquity pacing, but there is a perplexing lack of precession variability despite its important influence on summer insolation intensity - the presumed forcing of ice sheet growth and decay according to the Milankovitch hypothesis. This puzzle has been explained in two ways: Northern Hemisphere ice sheets instead respond to insolation integrated over the summer, which is mostly controlled by obliquity, or anti-phased precession-driven variability in ice volume between the hemispheres cancels out in global O-18, leaving the in-phase obliquity signal to dominate. We evaluated these ideas by reconstructing Laurentide Ice Sheet (LIS) meltwater discharge to the Gulf of Mexico from 2.55-1.70Ma using...

Ocean warming, eutrophication and consequent decrease in oxygen lead to smaller average fish size. Although such responses are well-known in an evolutionary context, involving multiple generations, it appears to be incompatible with current rapid environmental change. Rather, phenotypic plasticity could provide a means for marine fish to cope with rapid environmental changes. However, little is known about the mechanisms underlying plastic responses to environmental conditions that favour small phenotypes.  Our aim was to investigate how and why European sea bass that had experienced a short episode of moderate hypoxia during their larval stage subsequently exhibited a growth depression at the juvenile stage compared to the control group.  We examined...

An Ecological Time Series of Pacific Oyster (C. gigas) Growth and Survival: data curation and analysis of 24 years of monitoring along the French coast
Provedor de dados: 5
Autores: Normand, Julien; Dubroca, Laurent; Fleury, Elodie.
As global change becomes a major concern, the need to contextualize discrete observations to highlight long-term evolutions also becomes more relevant. In response to this challenge, Marine Historical Ecology (MHE) has recently emerged as a new discipline within the marine sciences, dedicated to studying the relationship between long-term evolution of marine ecosystems and temporal variations of external predictors such as meteorological parameters, or descriptors of human activities. In recent years, therefore, considerable effort has been devoted to study long-term time series on fisheries and environmental data. This approach has increased our knowledge about natural variability and functioning of marine environments and has helped us to characterize...

Autores: Lassalle, Geraldine; Gascuel, Didier; Le Loch, Francois; Lobry, Jeremy; Pierce, Graham John; Ridoux, Vincent; Santos, Maria Begona; Spitz, Jerome; Niquil, Nathalie.
A number of marine mammal populations is currently threatened by their interactions with fisheries. The present study aimed to provide insights into the severity of potential impacts of operational and biological interactions between top predators and fisheries, in the Bay of Biscay region. Our approach was to modify an Ecopath with Ecosim (EwE) model describing the overall structure and function of the ecosystem by including landings and discards of exploited stocks and estimations of the bycatch of non-target compartments. Second, a set of ecological indices and a trophic level (TL)-based model (EcoTroph, ET) were derived from the EwE model. ET was used to simulate the effects of increasing fishing pressure on the ecosystem and, more particularly, on top...

An ecosystem-based approach to bivalve aquaculture management is a strategy for the integration of aquaculture within the wider ecosystem, including human aspects, in such a way that it promotes sustainable development, equity, and resilience of ecosystems. Given the linkage between social and ecological systems, marine regulators require an ecosystem-based decision framework that structures and integrates the relationships between these systems and facilitates communication of aquaculture-environment interactions and policy-related developments and decisions. The Drivers-Pressures-State Change-Impact-Response (DPSIR) management framework incorporates the connectivity between human and ecological issues and would permit available performance indicators to...

The numbers of potential neurotoxicants in the environment are raising and pose a great risk for humans and the environment. Currently neurotoxicity assessment is mostly performed to predict and prevent harm to human populations. Despite all the efforts invested in the last years in developing novel in vitro or in silico test systems, in vivo tests with rodents are still the only accepted test for neurotoxicity risk assessment in Europe. Despite an increasing number of reports of species showing altered behaviour, neurotoxicity assessment for species in the environment is not required and therefore mostly not performed. Considering the increasing numbers of environmental contaminants with potential neurotoxic potential, eco-neurotoxicity should be also...

An eddy-permitting model of the Atlantic circulation: Evaluating open boundary conditions
Provedor de dados: 5
Autores: Treguier, Anne-marie; Barnier, B; De Miranda, A; Molines, J; Grima, N; Imbard, M; Madec, Gerard; Messager, Christophe; Reynaud, Thierry; Michel, Sylvain.
As part of the French CLIPPER project, an eddy permitting model of the Atlantic circulation has been run for 22 years. The domain has open boundaries at Drake passage and at 30 degreesE, from Africa to Antarctica. The simulated mean circulation, as well as the eddy activity, is satisfactory for a 1/3 degrees model resolution, and the meridional heat transport at 30 degreesS is within the range estimated from observations. We use the "mixed" open boundary algorithm of Barnier et al. [1998], which has both a radiation condition and a relaxation to climatology. The climatological boundary forcing strongly constrains the solution in the whole domain. The model heat balance adjusts through the surface (heat flux retroaction term) more than the open boundaries....

An eDNA/eRNA‐based approach to investigate the life cycle of non‐cultivable shellfish micro‐parasites: the case of   Bonamia ostreae   , a parasite of the European flat oyster   Ostrea edulis
Provedor de dados: 5
Autores: Mérou, Nicolas; Lecadet, Cyrielle; Pouvreau, Stephane; Arzul, Isabelle.
Environmental DNA approaches are increasingly used to detect microorganisms in environmental compartments, including water. They show considerable advantages to study non‐cultivable microorganisms like Bonamia ostreae, a protozoan parasite inducing significant mortality in populations of flat oyster Ostrea edulis . Although B. ostreae development within the host has been well described, questions remain about its behaviour in the environment. As B. ostreae transmission is direct, seawater appears as an interesting target to develop early detection tools and improve our understanding of disease transmission mechanisms. In this context, we have developed an eDNA/eRNA approach allowing detecting and quantifying B. ostreae 18S rDNA/rRNA as well as monitoring...

Autores: Romestand, B; Dragesco, A; Breuil, Gilles; Coste, F; Bouix, G.
Three batches of rabbits were immunized against 2 strains of Vibrio anguillarum (Va V 62 and Va V 408), which cause vibriosis in sea bass Dicentrarchus labrax (L. 1758) Serranidae. Homologous and heterologous reactions were obtained against these Vibrio strains and other bacteria using an improved indirect ELISA technique. Antibody and antigen titrations revealed high immunogenecity (high antibody titers for the antisera) of the 2 Vibrio strains. They correspond to serotype I and show close affinity. The specificity and sensitivity of 1 selected antiserum were tested on brain extracts from healthy sea bass and those infected artificially with V. anguillarum serotypes I and III. Preliminary results confirm the reliability of the technique and warrant its...

A small Prorocentrum species was found during a pilot taxonomic survey of marine benthic dinoflagellates in the northwestern Arabian Sea, Oman. Based on the study of cells from natural samples and laboratory cultures using light and scanning electron microscopy, this taxon is attributed to the little-known Prorocentrum sipadanense, recorded so far only from East Malaysia. The description of this species has been emended to include details of internal cell structure, composition of its periflagellar area and intraspecific variability in size, shape and pore pattern. Round to oval or ovoid cells of P. sipadanese are surrounded by a prominent marginal ridge and are 17.9–23.9 µm long and 15.0–19.8 µm wide, with a foveate to reticulate thecal plate surface and...

An empirical model to predict the lifetime of braided HMPE handling ropes under cyclic bend over sheave (CBOS) loading
Provedor de dados: 5
Autores: Davies, Peter; Francois, M; Lacotte, Nicolas; Vu, Thanh Do; Durville, Damien.
Repeated bending over sheaves is one of the main causes of failure of synthetic fibre ropes used in marine operations. There are few published results available and even fewer models allowing lifetime to be estimated. A large new set of data from cyclic bend over sheave (CBOS) tests on 250 kN break load braided HMPE synthetic ropes is presented first, both tests to failure and interrupted tests followed by residual strength measurements. These data are analysed in order to propose an empirical lifetime model. This is identified using constant load tests, then evaluated for variable load sequences. A methodology to include rope lifetime prediction in handling system design is then discussed.

An end-to-end coupled model ROMS-N(2)P(2)Z(2)D(2)-OSMOSE of the southern Benguela foodweb: parameterisation, calibration and pattern-oriented validation
Provedor de dados: 5
Autores: Travers-trolet, Morgane; Shin, Yunne-jai; Field, J. G.
In order to better understand ecosystem functioning under simultaneous pressures (e.g. both climate change and fishing pressures), integrated modelling approaches are advocated. We developed an end-to-end model of the southern Benguela ecosystem by coupling the high trophic level model OSMOSE with a biophysical model (ROMS-N(2)P(2)Z(2)D(2)). OSMOSE is a spatial, multispecies, individual-based model simulating the whole life cycle of fish with fish schools interacting through opportunistic and size-based predation. It is linked to the biogeochemical model through the predation process; plankton groups are food for fish and fish apply a predation mortality on plankton. Here we describe the two-way coupling between the models and follow a pattern-oriented...

The Mediterranean Sea is now recognized as a hotspot of global change, ranking among the fastest warming ocean regions. In order to project future plausible scenarios of marine biodiversity at the scale of the whole Mediterranean basin, the current challenge is to develop an explicit representation of the multispecies spatial dynamics under the combined influence of fishing pressure and climate change. Notwithstanding the advanced state-of-the-art modeling of food webs in the region, no previous studies have projected the consequences of climate change on marine ecosystems in an integrated way, considering changes in ocean dynamics, in phyto- and zoo-plankton productions, shifts in Mediterranean species distributions and their trophic interactions at the...

Autores: Halouani, Ghassen; Le Loc'H, François; Shin, Yunne-jai; Velez, Laure; Hattab, Tarek; Romdhane, Mohamed Salah; Ben Rais Lasram, Frida.
In order to assist fisheries managers, ecological indicators are needed to evaluate the effects of fishing activities on marine ecosystems and to improve communication of these effects in both public and scientific contexts. Finding appropriate indicators is challenging given the complexity of marine food webs as well as the ecosystem response to fishing pressure. In this study, an end-to-end model developed in the Gulf of Gabes ecosystem (Tunisia) was used to compare the performance of a set of ecosystem indicators in assessing the impact of fishing. This end-to-end model aimed to represent the ecosystem functioning by coupling two existing sub-models, the multispecies individual-based model OSMOSE, representing the dynamics of exploited species and the...

Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants still present in aquatic environments despite their total or partial ban. Previously, we observed that an environmentally realistic mixture of these compounds affects energy balance, growth, and reproduction in exposed zebrafish (F0), and behavior in their unexposed offspring (F1-F4). In the present work, we performed lipidomic and transcriptomic analyses on brains of zebrafish (F0-F2) from exposed and control lineages to identify molecular changes that could explain the observed phenotypes. The use of both technologies highlighted that F0 zebrafish displayed impaired mitochondrial function and lipid metabolism regulation (depletion in...

We develop, calibrate and test a dataset intended to drive global ocean hindcasts simulations of the last five decades. This dataset provides surface meteorological variables needed to estimate air-sea fluxes and is built from 6-hourly surface atmospheric state variables of ERA40. We first compare the raw fields of ERA40 to the CORE.v1 clataset of Large and Yeager (2004). used here as a reference, and discuss our choice to use daily radiative fluxes and monthly precipitation products extracted from satellite data rather than their ERA40 counterparts. Both datasets lead to excessively high global imbalances of heat and freshwater fluxes when tested with a prescribed climatological sea surface temperature. After identifying unrealistic time discontinuities...

An Estimate of Thorium 234 Partition Coefficients Through Global Inverse Modeling
Provedor de dados: 5
Autores: Le Gland, Guillaume; Aumont, Olivier; Memery, Laurent.
Thorium-234 (Th-234), an insoluble radioisotope scavenged by marine particles, can be used as a proxy of the biological carbon pump. Thorium-234 observations can constrain biogeochemical models, but a necessary first step is to estimate the poorly known partition coefficients between particulate and dissolved phases. In this study, the Th-234 partition coefficients for five particle types, differing in size and chemical composition, are estimated by fitting a global 3-D Th-234 model based on the coupled ocean general circulation-biogeochemistry model NEMO-PISCES (at a resolution of 2 degrees) to a global Th-234 data set (including GEOTRACES data). Surface partition coefficients are estimated between 0.79 and 16.7x10(6). Biogenic silica has the smallest...

An estuarine mud flat re-surveyed after forty-five years

Autores: Mettam, C.
The distribution of infauna across an estuarine mud flat, described by C. B. Rees in 1940, remains very similar more than 40 years later in spite of environmental changes that have occurred meanwhile. The apparent stability of the distribution and abundance of species is probably related to a constancy in the distribution of sediments on an eroding shoreline. Several species occur at greatest densities in restricted sections of the shore and lower densities elsewhere represent an outward spread of colonising individuals that do not survive to maturity.

An evaluation of benthic foraminiferal U/Ca and U/Mn proxies for deep ocean carbonate chemistry and redox conditions
Provedor de dados: 5
Autores: Chen, Pujiao; Yu, Jimin; Jin, Zhangdong.
The deep ocean is thought to have played a crucial role in modulating atmospheric CO2 changes, and thus reconstructions of deep ocean conditions can place important constraints on the past global carbon cycle. Some previous studies suggested that foraminiferal U/Ca could be used to infer seawater carbonate chemistry changes, but others showed complications from diagenesis and temperature. A recent downcore study suggested that foraminiferal U/Mn may be used for sedimentary redoxconditions, but no core-top work has been done to investigate factors affecting U/Mn. We investigate controlling factors on U/Ca and U/Mn in two benthic foraminiferal species from 120 global core-tops and three Atlantic sediment cores. Our core-top data reveal no significant...

An evaluation of changes in stock productivity and consequences for management. An example based on North Atlantic albacore Thunnus alalunga
Provedor de dados: 5
Autores: Kell, Laurence T; Fromentin, Jean-marc.
Reference points are important elements of fisheries management and the supporting scientific advisory frameworks. However, fish stocks can fluctuate extensively over a large range of spatial and temporal scales independent of human exploitation and there has been a classical tendency to assume a dichotomy, i.e., that changes in fish populations are primarily attributable either to exploitation or to environmental variability. Therefore we look at variability in surplus production and examine the relative impacts of the environment and exploitation on the productivity of North Atlantic albacore (Thunnus alalunga). The analysis revealed that variations were driven by environmental effects. It was also found that substantial variations in time-series of...

The influence of salinity and water chemistry on Mg/Ca, Sr/Ca and Ba/Ca ratios in the aragonitic shells of the Manila clam were investigated. Clams were reared at constant temperature (20 °C) under different controlled conditions of salinity, commonly encountered in their natural habitat. Clams were held in three tanks with a constant salinity of 35 for the first 35 days and then two tanks were changed to lower salinities (20 and 28) for the next 29 days. Individual shell Mg/Ca, Sr/Ca and Ba/Ca ratios were studied through time. Despite stable conditions (temperature, salinity, and Mg/Cawater) for clams reared at salinity 35 during the experiment, Mg/Ca shell ratios increased through the time. Moreover the salinity decrease at t35 slowed the increase of...

Current scientific management objectives for ICES roundfish stocks are to ensure conservation of the biological resource and do not explicitly consider economic or social objectives. For example, there are currently no objectives to maximize the sustainable yield or to reduce variability in total allowable catches (TACs). This is despite the fact that the current system can result in wide annual fluctuations in TAC, limiting the ability of the fishing industry to plan for the future. Therefore, this study evaluated management strategies that stabilized catches by setting bounds on the interannual variability in TACs. An integrated modelling framework was used, which simulated both the real and observed systems and the interactions between system...

Provedor de dados: 5
Autores: Faur, Florian; Saini, Camille; Potter, Gael; Galgani, Francois; De Alencastro, Luiz Felippe; Hagmann, Pascal.
This study examines the distribution, abundance and characteristics of surface micro- and mesoplastic debris in the Western Mediterranean Sea. 41 samples were collected in 2011 (summer) and 2012 (summer). Results, firstly, revealed that micro- (&lt;5mm) and mesoplastic debris were widely and uniformly distributed in this area with average concentrations of 130,000 parts/km(2) and 5700 parts/km(2), respectively. Importantly, a strong correlation between micro- and mesoplastic concentrations was identified. Secondly, a classification based on the shape and appearance of microplastics indicated the predominant presence of fragments (73 %) followed by thin films (14 %). Thirdly, the average mass ratio of microplastic to dry organic matter has been measured at...

An evaluation of the implications of population structure on the current bluefin tuna advice framework
Provedor de dados: 5
Autores: Kell, Laurence T; Fromentin, Jean-marc; Bonhommeau, Sylvain.
The objectives of the comprehensive ICCAT Atlantic-Wide Research Programme on Bluefin Tuna (GBYP) are to improve data collection, knowledge of key biological and ecological processes, assessment models and management. An important element of which is to develop a robust advice framework consistent with the Precautionary Approach. The current advice framework, which is based upon Virtual Population Analysis, demonstrates how a Management Strategy Evaluation (MSE) framework can be used to evaluate the robustness of management advice to uncertainty about stock structure.

An evaluation of the policy of fishery resources management by TACs in European Community waters from 1983 to 1992
Provedor de dados: 5
Autores: Biais, Gerard.
In 1983, the European Community (EC) agreed on a system for the conservation and management of fishery resources whi h is based largely on the use of annual total allowable catch (TAC). Nevertheless, the state of many European stocks of demersal species has worsened since 1983. A review of TAC enforcement shows that landings have exceeded TACs to a limited estent for these resources. The contrary is observed for the stocks of pelagic species of which the state has improved although landings have frequently been larger than TACs. This double paradox generates a feeling of limited impact of the TAC system inmplemented by the EC. To investigate the reasons, the closeness between agreed TACs and scientific recommendations has been examined. The results show...

Autores: Laugier, Thierry; Malet, Nathalie; Munaron, Dominique; Derolez, Valerie; Fiandrino, Annie; Barral, Marc; Moragues, Laurent; Mazouni, Nabila; Graille, Chantal.
The poster presents the approach that led to the construction of a network of cooperation between managers and scientists for coastal lagoon management in the region of Languedoc-Roussillon, its architecture and modus operandi, its achievements and developments over time.  At the end of the ninety’s, eutrophication and lack of knowledge were identified as issues to enhance the management of coastal lagoons on the Mediterranean coast of France. In 2000, in the region of Languedoc-Roussillon, scientists (Ifremer) and institutional managers (Regional Council of Languedoc-Roussillon and Water Agency Rhône-Méditerranée &amp; Corse) joined their forces in building a network to address this need. The core of this network consists of an operational tool for the...

An example of GIS potentiality for coastal zone management: preselection of submerged oyster culture areas near Marennes-Oleron (France)
Provedor de dados: 5
Autores: Durand, H.; Guillaumont, Brigitte; Loarer, Ronan; Loubersac, Lionel; Heral, Maurice; Prou, Jean.
The Charente Maritime coast, in central western France, is the most important area for oyster and mussel production in Europe. High density, in this restricted intertidal area, induces low growing rate and socio-economic difficulties. One of the possible solutions is to shift some oysters from intertidal area to submerged areas. Bathymetry, sedimentology, hydrodynamism, fisheries and administrative rules are some conditions which are considered to establish the better selection of potential zone. The successive steps of setting up the prototype of GIS are presented: digitized traditional data from charts, extracted data from grid models (hydrodynmaic model), merging of thematic covers, proposal of favorable areas. The results are discussed especially on...

An experimental and numerical study of FSI applied to sail yacht flexible hydrofoil with large deformations
Provedor de dados: 5
Autores: Temtching Temou, Vanilla; Fagherazzi, Odran; Augier, Benoit; Astolfi, Jacques-andré; Raison, David.
The recent use of large aspect ratio and highly loaded composite hydrofoils on sailing boats illustrates the limit of the assumption of rigid body. When flying, the hydrofoil presents large deformations which impact significantly the hydrodynamic loads expected. The present work focuses on an experimental campaign performed on a trapezoidal hydrofoil, made of polyacetate material, in the hydrodynamic tunnel at the Research Institute of French Naval Academy. Large deformations up to 4.5% of the span on the hydrofoil’s tip are measured at angle of incidence 10° for Re=0:7 x 10 6 calculated at mean chord. Vibration analysis performed on this foil, highlights an increase of its resonance frequencies with bending loading. A coupled approach between the Vortex...

Autores: Sheehan, Emma V.; Vaz, Sandrine; Pettifer, Erin; Foster, Nicola L.; Nancollas, Sarah J.; Cousens, Sophie; Holmes, Luke; Facq, Jean-valery; Germain, Gregory; Attrill, Martin J.
Managing ecological systems, which operate over large spatial scales, is inherently difficult and often requires sourcing data from different countries and organizations. The assumption might be made that data collected using similar methodologies are comparable, but this is rarely tested. Here, benthic video data recorded using different towed underwater video systems (TUVSs) were experimentally compared.   Three technically different TUVSs were compared on different seabed types (rocky, mixed ground and sandy) in Kingmere Marine Conservation Zone, off the south coast of England. For each TUVS, species metrics (forward facing camera), seabed impact (backward facing camera) and operational performance (strengths and limitations of equipment and video...

An experimental study of water diffusion in carbon/epoxy composites under static tensile stress
Provedor de dados: 5
Autores: Humeau, Corentin; Davies, Peter; Jacquemin, Frederic.
The coupling between tensile stress and water diffusion in composites represents a major issue in many marine applications. Even if these two behaviours are well documented as separate subjects, there are still very few data on fully coupled mechanisms. The aim of this study is to understand what governs the coupled behaviour, by investigating the water diffusion in carbon/epoxy. The coupling is first evaluated on neat resin samples to characterise the matrix behaviour. Then the study focuses on composites with two types of woven fibre orientation: one at ±45°, in order to understand the coupling effects on materials loaded away from the reinforcement direction and another quasi-isotropic to obtain properties along the fibres. For each material the same...

An experimental/numerical study of the catch weight influence on trawl behavior
Provedor de dados: 5
Autores: Priour, Daniel; De La Prada, Amelia.
Measurements at sea during fishing trials on bottom trawl have revealed that the geometry of the trawl is affected by the catch. A series of 37 hauls of around 3 h were carried out during the French EFFICHALUT project. The aim of this project was to carry out improvements on the fishing gear in order to reduce energy consumption. For this project, numerous sensors were used: for bridle tension, door spread, vertical opening, and door attitude. The measurements show quite clearly that the door spread decreases and the bridle tension increases during most of the hauls. The door spread decreased by 1.35 m/h, with a standard deviation of 1.98 m/h while the top bridle tension increased by 47 kg/h, with a standard deviation of 59 kg/h. The mean catch per haul...

In Archaea, the proteins involved in the genetic information processing pathways, including DNA replication, transcription, and translation, share strong similarities with those of eukaryotes. Characterizations of components of the eukaryotic-type replication machinery complex provided many interesting insights into DNA replication in both domains. In contrast, DNA repair processes of hyperthermophilic archaea are less well understood and very little is known about the intertwining between DNA synthesis, repair and recombination pathways. The development of genetic system in hyperthermophilic archaea is still at a modest stage hampering the use of complementary approaches of reverse genetics and biochemistry to elucidate the function of new candidate DNA...

An hybrid approach for the comparison of VAWT and HAWT performances for floating offshore wind turbines
Provedor de dados: 5
Autores: Matoug, Camil; Augier, Benoit; Paillard, B; Maurice, G; Sicot, C; Barre, S.
This article describes the experimental comparison of the DTU 10MW HAWT with the WindQuest 10MW VAWT scaled models when both fitted on the Nautilus-10 semisubmersible. For the campaign in Ifremer Wind&amp;Wave tank, different rotor representations are tested from inertia only to hybrid testing with propellers and a Software in the Loop. The hybrid testing uses a tabulated approach for thrust computation and is discussed in this article. The different thrust reproduction methods are compared to OpenFAST simulations calibrated during the Lifes50+ project and used as reference points. When quantifying the scale model's fidelity to Open Fast, cross-correlation was increased up to 14% with the use of the SiL. Thanks to the validation of hydrodynamic simulations...

An hydrodynamic shear instability in stratified disks
Provedor de dados: 5
Autores: Dubrulle, B; Marie, Louis; Normand, C; Richard, D; Hersant, F; Zahn, Jp.
We discuss the possibility that astrophysical accretion disks are dynamically unstable to non-axisymmetric disturbances with characteristic scales much smaller than the vertical scale height. The instability is studied using three methods: one based on the energy integral, which allows the determination of a sufficient condition of stability, one using a WKB approach, which allows the determination of the necessary and sufficient condition for instability and a last one by numerical solution. This linear instability occurs in any inviscid stably stratified differential rotating fluid for rigid, stress-free or periodic boundary conditions, provided the angular velocity Omega decreases outwards with radius r. At not too small stratification, its growth rate...

An Hypothesis Concerning the Relationships Between Submarine Hot Springs and the Origin of Life on Earth

Autores: Corliss, J B; Baross, Ja; Hoffman, Se.
A diverse set of observations from Archaean fossil-bearing rocks, modern submarine hydrothermal systems, experimental and theoretical work on the abiotic synthesis of organic molecules and primitive organized structures, and on water-rock interactions suggests that submarine hot springs were the site for the synthesis of organic compounds leading to the first living organisms on earth. These systems are characterized by high fluxes of thermal energy, highly reducing conditions, abundant and appropriate catalytic surface areas (Fe-Mg clay minerals), significant concentrations of CH sub(4), NH sub(3), H sub(2), metals, etc., and a continuous convective flow which removes products from the site of reaction upward through a mixing gradient of temperature and...

An improved method for estimating water-mass ventilation age from radiocarbon data
Provedor de dados: 5
Autores: Devries, Tim; Primeau, Francois.
Existing methods for inferring the ventilation age of water masses in the ocean using radiocarbon data neglect the effects of diffusive mixing. in the presence of varying atmospheric Delta(14)C, this neglect produces spurious time dependence in the estimated ventilation ages. To correct this deficiency we propose a new method for estimating the ventilation age from sediment core radiocarbon data. The new method is formulated in terms of parameterized age distributions that account for the effects of advective and diffusive transport in the ocean. When applied to simulated radiocarbon data from an OGCM, the method is able to closely reproduce the modeled ventilation age, whereas other methods are not. We also applied the method to sediment-core radiocarbon...

An Improved Protocol for Flow Cytometry Analysis of Phytoplankton Cultures and Natural Samples
Provedor de dados: 5
Autores: Marie, Dominique; Rigaut-jalabert, Fabienne; Vaulot, Daniel.
Preservation of cells, choice of fixative, storage, and thawing conditions are recurrent issues for the analysis of phytoplankton by flow cytometry. We examined the effects of addition of the surfactant Pluronic F68 to glutaraldehyde-fixed photosynthetic organisms in cultures and natural samples. In particular, we examined cell losses and modifications of side scatter (a proxy of cell size) and fluorescence of natural pigments. We found that different marine phytoplankton species react differently to the action of Pluronic F68. In particular, photosynthetic prokaryotes are less sensitive than eukaryotes. Observed cell losses may result from cell lysis or from cell adhesion to the walls of plastic tubes that are commonly used for flow cytometry analysis....

The jellyfish species Clytia hemisphaerica (Cnidaria, Hydrozoa) has emerged as a new experimental model animal in the last decade. Favorable characteristics include a fully transparent body suitable for microscopy, daily gamete production and a relatively short life cycle. Furthermore, whole genome sequence assembly and efficient gene editing techniques using CRISPR/Cas9 have opened new possibilities for genetic studies. The quasi-immortal vegetatively-growing polyp colony stage provides a practical means to maintain mutant strains. In the context of developing Clytia as a genetic model, we report here an improved whole life cycle culture method including an aquarium tank system designed for culture of the tiny jellyfish form. We have compared different...

Here we tested two non-standard ones, HE800 and GY785, for the two-dimensional (2-D) and three-dimensional (3-D) culture of osteoblasts (MC3T3-E1) and chondrocytes (C28/I2). These two glycosaminoglycan-like marine exopolysaccharides were incorporated into an injectable silylated hydroxypropylmethylcellulose-based hydrogel (Si-HPMC) that has already shown its suitability for bone and cartilage tissue engineering. Results showed that, similarly to hyaluronic acid (HA) (the control), HE800 and GY785 significantly improved the mechanical properties of the Si-HPMC hydrogel and induced the attachment of MC3T3-E1 and C28/I2 cells when these...

Autores: Assassi, Charefeddine; Morel, Y.; Vandermeirsch, Frederic; Chaigneau, A.; Pegliasco, C.; Morrow, R.; Colas, F.; Fleury, S.; Carton, Xavier; Klein, Patrice; Cambra, R.
In this study, we first show that it is difficult to reconstruct the vertical structure of vortices using only surface observations. In particular we show that the recent SQG and ISQG methods systematically lead to surface intensified vortices and those subsurface intensified vortices are thus not correctly modelled.  We then investigate the possibility to distinguish between surface and subsurface intensified eddies from surface data only, using the sea surface height and the sea surface temperature available from satellite observations. A simple index, based on the ratio of the sea surface temperature anomaly and the sea level anomaly, is proposed. While the index is expected to give perfect results for isolated vortices, we show that in a complex...

An Indo-Pacific see-saw wobbles the Earth at intraseasonal timescales
Provedor de dados: 5
Strong large-scale winds can relay their energy to the ocean bottom and elicit an almost immediate intraseasonal barotropic (depth independent) response in the ocean. The intense winds associated with the Madden-Julian Oscillation (MJO), over the tropical interface between the Indian Ocean and the Pacific Ocean (popularly known as Maritime Continent) generate significant basin-wide intraseasonal barotropic sea level variability in the tropical Indian Ocean. Here we show, using an ocean general circulation model and a network of in-situ bottom pressure recorders, that the concerted barotropic response of the Indian and the Pacific Ocean to these winds leads to an intraseasonal see-saw of oceanic mass in the Indo-Pacific basin. This global-scale mass shift...

The authors report the presence of a Rickettsia in Ruditapes decussatus from natural populations of the Algarve (Portugal). Light microscopic shows infections of varying importance in gill tissues. Some enclose small procaryotic colonies (cp) scattered in all lamellae; in others, the colonies are scarce and hypertrophic (100 mu m). These different pictures suggest an amplification process. Digestive diverticulae may also be infected, but to a lesser extent. The ultrastructural features of this intravacuolar (mvd: densified vacuolar membrane) procaryote (P) and its multiplication by scission without a complex developmental cycle allows its classification in the order Rickettsiales.

The ocean plays a vital role in the global climate system and biosphere, providing crucial resources for humanity including water, food, energy, and raw materials. There is a compelling need to develop an integrated basin-scale ocean observing system to support of ocean management. We articulate a vision for basin-scale ocean observing – A comprehensive All-Atlantic Ocean Observing Systems that benefits all of us living, working and relying on the ocean. Until now, basin-scale ocean observation has been conducted through loosely-aligned arrangements of national and international efforts. The All-Atlantic Ocean Observing System (AtlantOS) is an integrated concept for a forward-looking framework and basin-scale partnership to establish a comprehensive ocean...

An integrated Bayesian modeling approach for the growth of Indian Ocean yellowfin tuna
Provedor de dados: 5
Autores: Dortel, Emmanuelle; Sardenne, Fany; Bousquet, N.; Rivot, Etienne; Million, Julien; Le Croizier, Gael; Chassot, Emmanuel.
The Indian Ocean Tuna Tagging Program provided a unique opportunity to collect demographic data on the key commercially targeted tropical tuna species in the Indian Ocean. In this paper, we focused on estimating growth rates for one of these species, yellowfin (Thunnus albacares). Whilst most growth studies only draw on one data source, in this study we use a range of data sources: individual growth rates derived from yellowfin that were tagged and recaptured, direct age estimates obtained through otolith readings, and length-frequency data collected from the purse seine fishery between 2000 and 2010. To combine these data sources, we used an integrated Bayesian model that allowed us to account for the process and measurement errors associated with each...

The objective of this study was to develop an integrative approach in ecotoxicology (from biomarkers to population genetics) to assess the ecological status of fish populations. Flounders (Platichthys flesus) collected after the spawning season in the heavily polluted Seine estuary were compared with the moderately polluted Bay of Douarnenez. The muscle energetic reserves were highly depleted in Seine vs. Douarnenez fish. The Seine fish displaying a reduced capacity to manage the oxidative stress and a higher energetic metabolism. An increase in the content of muscle membrane phospholipids (sphingomyelin, phosphatidylserine, free sterols) was detected in the Seine vs. Douarnenez fish. The data integration allowed to hypothesize relationships between...

An integrated fish-plankton aquaculture system in brackish water
Provedor de dados: 5
Autores: Gilles, S.; Fargier, L.; Lazzaro, X.; Baras, E.; De Wilde, Nicolas; Drakides, C.; Amiel, C.; Rispal, B.; Blancheton, Jean-paul.
Integrated Multi-Trophic Aquaculture takes advantage of the mutualism between some detritivorous fish and phytoplankton. The fish recycle nutrients by consuming live (and dead) algae and provide the inorganic carbon to fuel the growth of live algae. In the meanwhile, algae purify the water and generate the oxygen required by fishes. Such mechanism stabilizes the functioning of an artificially recycling ecosystem, as exemplified by combining the euryhaline tilapia Sarotherodon melanotheron heudelotii and the unicellular alga Chlorella sp. Feed addition in this ecosystem results in faster fish growth but also in an increase in phytoplankton biomass, which must be limited. In the prototype described here, the algal population control is exerted by herbivorous...

A wide range of geophysical and sedimentological investigations on upper slope sediments of the eastern Porcupine Seabight, SW of Ireland, allowed to evaluate the local importance of bottom currents throughout the Upper Paleogene to recent times, as well as the influence of, and interplay with other deep-water sedimentary processes. The tools available for this study mainly allowed to focus on the nature and characteristics of the Quaternary deposits of seismic unit U1, but also documented buried Middle Eocene to Pliocene sediment drifts and sediment waves. A Late Pliocene erosional event (RD1) created a highly irregular discontinuity, observed from the northern part of the Belgica mound province towards the southern Gollum channel and Goban Spur.

An integrative approach to species delimitation in Benthomangelia (Mollusca: Conoidea)
Provedor de dados: 5
Autores: Puillandre, Nicolas; Baylac, Michel; Boisselier, Marie-catherine; Cruaud, Corinne; Samadi, Sarah.
DNA sequences are currently used to propose primary hypotheses of species delimitation, especially when morphological variability is difficult to assess. In an integrative taxonomy framework, these hypotheses are then compared with other characters, such as morphology or geography, to produce robust species delimitations. For this purpose, the cytochrome oxidase subunit I (COI) gene has been sequenced for almost 50 specimens of the genus Benthomangelia, a deep-sea marine gastropod genus, collected in the South-West Pacific. Five genetic groups, displaying low and high genetic distances respectively within and between groups, were defined. COI hypotheses were compared with both the results obtained with the independent nuclear 28S gene and with an elliptic...

An integrative framework of coexistence mechanisms in competitive metacommunities
Provedor de dados: 5
Autores: Fournier, Bertrand; Mouquet, Nicolas; Leibold, Mathew A.; Gravel, Dominique.
Species distribution in a metacommunity varies according to their traits, the distribution of environmental conditions and connectivity among localities. These ingredients contribute to coexistence across spatial scales via species sorting, patch dynamics, mass effects and neutral dynamics. These mechanisms however seldom act in isolation and the impact of landscape configuration on their relative importance remains poorly understood. We present a new model of metacommunity dynamics that simultaneously considers these four possible mechanisms over spatially explicit landscapes and propose a statistical approach to partition their contribution to species distribution. We find that landscape configuration can induce dispersal limitations that have negative...

An intercomparison of Arctic ice drift products to deduce uncertainty estimates
Provedor de dados: 5
Autores: Sumata, Hiroshi; Lavergne, Thomas; Girard-ardhuin, Fanny; Kimura, Noriaki; Tschudi, Mark A.; Kauker, Frank; Karcher, Michael; Gerdes, Rudiger.
An intercomparison of four low-resolution remotely sensed ice-drift products in the Arctic Ocean is presented. The purpose of the study is to examine the uncertainty in space and time of these different drift products. The comparison is based on monthly mean ice drifts from October 2002 to December 2006. The ice drifts were also compared with available buoy data. The result shows that the differences of the drift vectors are not spatially uniform, but are covariant with ice concentration and thickness. In high (low) ice-concentration areas, the differences are small (large), and in thick (thin) ice-thickness areas, the differences are small (large). A comparison with the drift deduced from buoys reveals that the error of the drift speed depends on the...

Existing coastal observatories in European waters are complex systems consisting of different observational components, providing crucial operational data for assessment, model validation and assimilation purposes. However, the geographical, structural, functional and operational heterogeneities that characterise them pose an enormous challenge to their efficient exploitation as information providers on a broader, cross-border, regional scale. To address this problem, the European Union (EU) Seventh Framework Programme (FP7) Towards a Joint European Research Infrastructure Network for Coastal Observatories (JERICO) project is creating a shared, pan-European framework for the networking of such observatories, promoting the identification and dissemination...

An intimate link between antimicrobial peptide sequence diversity and binding to essential components of bacterial membranes
Provedor de dados: 5
Autores: Schmitt, Paulina; Rosa, Rafael D.; Destoumieux-garzon, Delphine.
Antimicrobial peptides and proteins (AMPs) are widespread in the living kingdom. They are key effectors of defense reactions and mediators of competitions between organisms. They are often cationic and amphiphilic, which favors their interactions with the anionic membranes of microorganisms. Several AMP families do not directly alter membrane integrity but rather target conserved components of the bacterial membranes in a process that provides them with potent and specific antimicrobial activities. Thus, lipopolysaccharides (LPS), lipoteichoic acids (LTA) or the peptidoglycan precursor Lipid II are targeted by a broad series of AMPs. Studying the functional diversity of immune effectors tells us about the essential residues involved in AMP mechanism of...

Real-time operational predictions of the major ocean basins which resolve the ocean mesoscale at mid-latitudes have become established in more than a dozen countries over the last 15 years. These predictions depend on the global ocean observing system (particularly satellite altimeters and the Argo profiling float system), high performance computers and sophisticated ocean models and data assimilation systems. They support an expanding range of information services for operations at sea, weather forecasts and protection of the environment. GODAE Oceanview (GOV) assists the groups developing these predictions. This paper provides an introduction to GOV and the papers in this special issue.

Fisheries and aquaculture in Japan and France are very different in terms of scale and management schemes. Japan, a leading country in the world for fisheries, has developed a unique mixed system of community based coastal management and licensing schemes for off-shore and distant-water fisheries. Increasing demand, changes in consumption and the heavy constraint of access limitation to third countries waters, make Japan more and more depending upon imports. Though few effort and access limitation schemes are locally implemented in France, most of the management rules comply with the Common Fisheries Policy (CFP). The basic lines are the technical measures, the Total Allowable Catches (TACs) allocated into quotas at the regional level and the reduction of...

An inverse approach to understanding benthic oxygen isotope records from the last deglaciation
Provedor de dados: 5
Autores: Amrhein, Daniel Edward.
Observations suggest that during the last deglaciation (roughly 20,000-10,000 years ago) the Earth warmed substantially, global sea level rose approximately 100 meters in response to melting ice sheets and glaciers, and atmospheric concentrations of carbon dioxide increased. This interval may provide an analog for the evolution of future climate. The ocean plays a key role in the modern climate system by storing and transporting heat, salt, and nutrients, but its role during the last deglaciation remains uncertain. Prominent signals of the last deglaciation in the ocean are a gradual warming and a decrease of the seawater oxygen isotope ratio 18O (a signature of melting land ice sheets). These changes do not occur uniformly in the ocean, but propagate like...

An inverse estimate of the dynamic topography of the ocean
Provedor de dados: 5
Autores: Legrand, P; Schrama, Ejo; Tournadre, Jean.
The mean dynamic topography of the surface of the ocean is estimated using a finite difference inverse model of the ocean circulation constrained by a prior TOPEX/Poseidon-EGM96 estimate and an ocean density climatology. The EGM96 geoid uncertainties are represented by their full covariance matrix. The model finds a solution that yields a new 1°-resolution dynamic topography estimate with a 5 cm precision. The existence of this solution suggests that the uncertainties in EGM96, despite being much smaller than in previous geopotential models, are nonetheless realistic. The geodetic information constrains the inverse estimate of the ocean circulation, particularly at high latitudes.

An inverse model of the large scale circulation in the South Indian Ocean
Provedor de dados: 5
Autores: Sultan, Emmanuelle; Mercier, Herle; Pollard, R.t.
An overview of the large-scale circulation of the South Indian Ocean (SIO) (10 degrees S-70 degrees S/20 degrees E-120 degrees E) is proposed based on historical hydrographic data (1903-1996) synthesized with a finite-difference inverse model. The in situ density, potential temperature and salinity fields of selected hydrographic stations are projected on the basis of EOFs. Then the EOF coefficients (the projected values) are interpolated on the model grid (1 degrees in latitude, 2 degrees in longitude) using an objective analysis whose spatial correlation functions are fitted to the data set. The resulting fields are the input of the inverse model. This procedure filters out the small-scale features. Twelve modes are needed to keep the vertical structures...

The impact of the fishing effort exerted by a vessel on a population depends on catchability, which depends on population accessibility and fishing power. The work investigated whether the variation in fishing power could be the result of the technical characteristics of a vessel and/or its gear or whether it is a reflection of inter-vessel differences not accounted for by the technical attributes. These inter-vessel differences could be indicative of a skipper/crew experience effect. To improve understanding of the relationships, landings per unit effort (lpue) from logbooks and technical information on vessels and gears (collected during interviews) were used to identify variables that explained variations in fishing power. The analysis was undertaken by...

An investigation of the heat budget of the Indian River lagoon, Florida, during winter months
Provedor de dados: 5
Autores: Smith, N P.
Meteorological records and water temperature data from a 119-day period in the winter of 1979-1980 are used to develop and verify a numerical model of local air-water heat energy exchanges in the Indian River lagoon, on the Atlantic coast of South Florida. In terms of day-to-day variability, the most important processes are latent heat exchanges, net incoming solar radiation and sensible heat exchanges - in that order. Cold fronts moving through the study area alternate warm, moist maritime tropical air with relatively cool, dry continental polar air behind the front. As a result, the amount of heat stored in lagoonal waters is most highly correlated with the sensible and latent heat flux terms. Combining the individual heating and cooling processes, daily...

TDFe concentrations ranged from 0.90 to 65.6 nmol L-1 above the plateau and from 0.34 to 2.23 nmol L-1 offshore of the plateau. Station C1 located south of the plateau, near Heard Island, exhibited very high values (329-770 nmol L-1). Apparent particulate iron (Fe-app), calculated as the difference between the TDFe and the dissolved iron measured on board (DFe) represented 95 +/- 5% of the TDFe above the plateau, suggesting that particles and refractory colloids largely dominated the iron pool. This paper presents a budget of DFe and...

An iron cycle cascade governs the response of equatorial Pacific ecosystems to climate change
Provedor de dados: 5
Autores: Tagliabue, Alessandro; Barrier, Nicolas; Du Pontavice, Hubert; Kwiatkowski, Lester; Aumont, Olivier; Bopp, Laurent; Cheung, William W. L.; Gascuel, Didier; Maury, Olivier.
Earth System Models project that global climate change will reduce ocean net primary production (NPP), upper trophic level biota biomass and potential fisheries catches in the future, especially in the eastern equatorial Pacific. However, projections from Earth System Models are undermined by poorly constrained assumptions regarding the biological cycling of iron, which is the main limiting resource for NPP over large parts of the ocean. In this study, we show that the climate change trends in NPP and the biomass of upper trophic levels are strongly affected by modifying assumptions associated with phytoplankton iron uptake. Using a suite of model experiments, we find 21st century climate change impacts on regional NPP range from −12.3% to +2.4% under a...

An objective take on defining sexual maturity in the plaice, Pleuronectes platessa (Linné, 1758)
Provedor de dados: 5
Autores: Sauger, Carine; Quinquis, Jerome; Lepoittevin, Mélanie; Heude-berthelin, Clothilde; Kellner, Kristell; Elie, Nicolas; Dubroca, Laurent.
The European plaice (Pleuronectes platessa) is a commercial species with stock management advice given through the estimation of fish length at maturity (L50) (Mahé et al., 2007). Estimating the maturity of fish species has been worked on by the International Council for the Exploration of the Sea (ICES) that wants to harmonize the definitions, terminologies and practices used to determine the different maturity phases. Project MATO (MATurité Objective des poissons par l’histologie quantitative) will, among other things, bring knowledge on the ovarian histology of the plaice in order to correlate histological maturity with macroscopic parameters like the size color and texture of the ovaries. With this knowledge, the aim of this study is to set up a...

An observing system simulation for Southern Ocean carbon dioxide uptake
Provedor de dados: 5
Autores: Majkut, Joseph D.; Carter, Brendan R.; Froelicher, Thomas L.; Dufour, Carolina O.; Rodgers, Keith B.; Sarmiento, Jorge L.
The Southern Ocean is critically important to the oceanic uptake of anthropogenic CO2. Up to half of the excess CO2 currently in the ocean entered through the Southern Ocean. That uptake helps to maintain the global carbon balance and buffers transient climate change from fossil fuel emissions. However, the future evolution of the uptake is uncertain, because our understanding of the dynamics that govern the Southern Ocean CO2 uptake is incomplete. Sparse observations and incomplete model formulations limit our ability to constrain the monthly and annual uptake, interannual variability and long-term trends. Float-based sampling of ocean biogeochemistry provides an opportunity for transforming our understanding of the Southern Ocean CO2 flux. In this work,...

An occurrence of Tuhua Tephra in deep-sea sediments from offshore eastern North Island, New Zealand
Provedor de dados: 5
Autores: Manighetti, B; Palmer, A; Eden, D; Elliot, M.
We identify c. 7000 cal yr BP Tuhua Tephra in a marine sediment core from offshore eastern North Island, New Zealand. Its mineral assemblage includes aegirine, which is diagnostic for the Tuhua (Mayor Island) Volcanic Centre, and electron microprobe analyses of glass shards yield compositions close to published analyses of the tephra onshore, closer to the source. Associated radiocarbon ages on planktonic foraminifera from the core show that its age lies within the range previously determined for the caldera-forming event that generated Tuhua Tephra. This occurrence, &gt;380 km southeast of the source, indicates that the dispersal of the ash was bi-directional, and that earlier estimates of this tephra's volume may be conservative.

An ocean drum: quasi-geostrophic energetics from a Riemann geometry perspective
Provedor de dados: 5
Autores: Jaramillo, Jose Luis.
We revisit the discussion of the energetics of quasi-geostrophic flows from a geometric perspective based on the introduction of an effective metric, built in terms of the flow stratification and the Coriolis parameter. In particular, an appropriate notion of normal modes is defined through a spectral geometry problem in the ocean basin (a compact manifold with boundary) for the associated Laplace-Beltrami scalar operator. This spectral problem can be used to systematically encode non-local aspects of stratification and topography. As examples of applications we revisit the isotropy assumption in geostrophic turbulence, identify (a patch of) the hyperbolic space H-3 as the leading-order term in the effective geometry for the deep mesoscale ocean and,...

An Ocean Wind Doppler Model Based on the Generalized Curvature Ocean Surface Scattering Model
Provedor de dados: 5
Autores: Said, Faozi; Johnsen, Harald; Chapron, Bertrand; Engen, Geir.
A Doppler centroid D-C model based on the generalized curvature ocean surface scattering model (generalized curvature model or GCM) is presented. Two key features are included in this model: a skewness-related phase coefficient based on empirical skewness coefficients of sea-surface-slope probability density function (pdf) for wind speed less than 10 m/s and effects from wave breaking for wind speed greater than 10 m/s. Simulated D-c values are exclusively compared with the empirical geophysical Doppler model function named CDOP, for hh and vv polarizations, various wind conditions, and incidence angles. Good agreement is found overall between CDOP and simulated D-C values. The overall bias for simulated Dc-vv with and without skewness are 2.63 versus...

Ocean colour is recognised as an Essential Climate Variable (ECV) by the Global Climate Observing System (GCOS); and spectrally-resolved water-leaving radiances (or remote-sensing reflectances) in the visible domain, and chlorophyll-a concentration are identified as required ECV products. Time series of the products at the global scale and at high spatial resolution, derived from ocean-colour data, are key to studying the dynamics of phytoplankton at seasonal and inter-annual scales; their role in marine biogeochemistry; the global carbon cycle; the modulation of how phytoplankton distribute solar-induced heat in the upper layers of the ocean; and the response of the marine ecosystem to climate variability and change. However, generating a long time series...

The rapid climatic variability characterising the Marine Isotopic Stage (MIS) 3 (similar to 60-30 cal ka BP) provides key issues to understand the atmosphere-ocean-cryosphere dynamics. Here we investigate the response of sea-surface paleoenvironments to the MIS3 climatic variability through the study of a high resolution oceanic sedimentological archive (core MD99-2281, 60 degrees 21' N; 09 degrees 27' W; 1197m water depth), retrieved during the MD114-IMAGES (International Marine Global Change Study) cruise from the southern part of the Faeroe Bank. This sector was under the proximal influence of European ice sheets (Fennoscandian Ice Sheet to the East, British Irish Ice Sheet to the South) during the last glacial and thus probably responded to the MIS3...

In the Marsden Square Grid System, or its derivations - and this is the system that most national and international oceanographic data acquisition centres employ  - the information is located geographically for statistical purposes by means of a grid consisting of 10°, 5° or 1° " squares ".  The system, an early one dating from 1850, has three major disadvantages, and this has meant that its numbering principle cannot be used for a grid whose smallest lattice is less than 1° of latitude by 1° of longitude.

An operational model to simulate post-accidental radionuclide transfers in Toulon marine area: preliminary development
Provedor de dados: 5
Autores: Duffa, Celine; Dufois, Francois; Coudray, Sylvain.
As part of its development of post-accident management tools, the French Institute for Radiological Protection and Nuclear Safety is setting up a model to simulate radionuclide dispersion in the Toulon marine area (one of France's main military ports). The model is based on the MARS 3D code developed by IFREMER. It reproduces hydro-sedimentation phenomena in the Bay of Toulon with a horizontal spatial resolution of 100 m and 30 vertical sigma levels and also factors in radioactive decay and dissolved/particulate distribution of the radionuclides studied. With no tide, the major currents in this area are generated by the wind. The model effectively reproduces the resulting hydrodynamic phenomena, which were measured throughout the summer of 2009 in the...

An optimized scheme of lettered marine isotope substages for the last 1.0 million years, and the climatostratigraphic nature of isotope stages and substages
Provedor de dados: 5
Autores: Railsback, L. Bruce; Gibbard, Philip L.; Head, Martin J.; Voarintsoa, Ny Riavo G.; Toucanne, Samuel.
A complete and optimized scheme of lettered marine isotope substages spanning the last 1.0 million years is proposed. Lettered substages for Marine Isotope Stage (MIS) 5 were explicitly defined by Shackleton (1969), but analogous substages before or after MIS 5 have not been coherently defined. Short-term discrete events in the isotopic record were defined in the 1980s and given decimal-style numbers, rather than letters, but unlike substages they were neither intended nor suited to identify contiguous intervals of time. Substages for time outside MIS 5 have been lettered, or in some cases numbered, piecemeal and with conflicting designations. We therefore propose a system of lettered substages that is complete, without missing substages, and optimized to...

An overview and brief description of common marine organic-walled dinoflagellate cyst taxa occurring in surface sediments of the Northern Hemisphere
Provedor de dados: 5

Organic-walled resting cysts of planktonic dinoflagellates occur commonly in modern marine sediment where they represent, with rare exceptions, the only geologically preservable part of the life cycle. Although many species do not produce fossilizable resting cysts, upper Quaternary sediments contain a diverse cyst record that is used frequently for paleoenvironmental reconstruction and stratigraphic analysis. Reconstructions of past sea-surface conditions rely on an understanding of the distributions of dinoflagellate cysts in modern sediments linked to their respective environmental parameters, underpinned by sound taxonomy and standardized nomenclature. Stratigraphic studies additionally require knowledge of morphological details to distinguish extant...

An overview of chemosynthetic symbioses in bivalves from the North Atlantic and Mediterranean Sea
Provedor de dados: 5
Autores: Duperron, Sebastien; Gaudron, Sylvie M.; Rodrigues, Clara; Cunha, Marina R.; Decker, Carole; Olu, Karine.
Deep-sea bivalves found at hydrothermal vents, cold seeps and organic falls are sustained by chemosynthetic bacteria which ensure part or all of their carbon nutrition. These symbioses are of prime importance for the functioning of the ecosystems. Similar symbioses occur in other bivalve species living in shallow and coastal reduced habitats worldwide. In recent years, several deep-sea species have been investigated from continental margins around Europe, West Africa, East America, the Gulf of Mexico, and from hydrothermal vents on the Mid-Atlantic Ridge. In parallel, numerous more easily accessible shallow marine species were studied. We here provide a summary of the current knowledge available on chemosymbiotic bivalves in the area ranging west-to-east...

Autores: Morales-nin, B; Cannizzaro, L; Massuti, E; Potoschi, A; Andaloro, F.
The Mediterranean small-scale fleet is highly adaptive, showing a dynamic fishing intensity and strategy, and exploiting seasonal abundant resources. In this area, the aggregatory behaviour under floats of juvenile fish has been used since ancient times to exploit oceanic migratory species such as dolphinfish (Coryphaena hippurus), using Fish Aggregating anchored Devices (fads). A total of 2 300 boats are engaged in this fishery from August to December, the main fishing areas being those around Malta, Tunisia, Sicily and Majorca. The fads ( arrow right m2) are made of different cheap floating materials, and are moored in fixed places, ranging from shore waters to areas 60 miles off the coast (1 500 m depth). Each boat deploys an average of 20 to 100 fads....

Provedor de dados: 5
Autores: Farrugio, Henri; Oliver, Pere; Biagi, Franco.
The Mediterranean sea is an area which has a longlived oceanographic tradition. Since the remote antiquity, it has been the object of observations and descriptions in which maritime activities and fishing hold a paramount place, This paper presents a synthetic view on the history of the fisheries research and its evolution in the area. The very rich mediterranean fauna and the highly multispecific nature of the catches certainly favoured the fact that the first works were mainly oriented towards attempts of exhaustive descriptions of the vital cycles and biological parameters of a given species. The passage from marine biology sensu-stricto to fisheries research is relatively recent in the Mediterranean, the first attempts to apply some mathematical...

Autores: Fonteneau, Alain; Fromentin, Jean-marc.
This paper develops a critical overview of the various problems and uncertainties faced in tuna stock assessment, management and conservation. This presentation is based on Atlantic tunas, but also on various tuna stocks worldwide. Tuna jisheries management is characterized by major uncertainties in the stock assessment; since these stock assessments are always done only on jishery data which are often biased. Fortunately most tuna stocks are showing a strong resistance to overfishing. These major characteristics of tuna stocks and jisheries, and the bias in the scientific analysis, are presented and discussed. As a result, many of the reference point recommended for the precautionary approach applied to jisheries are often quite inappropriate for tuna...

Following the notification of nine hepatitis A cases clustered in the Cotes d'Armor district in northwestern France, epidemiological, environmental and microbiological investigations were set up in order to identify the source and vehicle of contamination and implement control measures. In total, 111 cases were identified in the outbreak, all of whom lived or had stayed as tourists in the Cotes d'Armor district. Of the cases, 87% had eaten raw shellfish, and 81% specifically oysters. Traceback investigations carried out on raw shellfish consumed by the cases showed that the raw shellfish originated from a single shellfish farm. The shellfish were probably contaminated either in the submersible tanks or in a depuration land-based tank where they were...

An underwater tracking system for mapping marine communities: an application to Posidonia oceanica
Provedor de dados: 5
Autores: Sgorbini, S; Peirano, A; Cocito, S; Morgigni, M.
The GPS intelligent buoy is a pot-table underwater tracking system consisting of four buoys and one pinger. The pinger was mounted on an underwater vehicle driven by a Scuba diver and used to map the limits of a Posidonia oceanica meadow. To test the accuracy of the method the system was tried out on different types of limits and on healthy and regressed part of the meadow from 2 to 25 m of depth. The time of track acquisition (1 point per second), the recording speed (1 km h(-1)) and the mapping scale (more than 1:500) indicated that the proposed method may be successfully integrated with conventional systems for mapping marine communities.

Autores: Boutron, Olivier; Bertrand, Olivier; Fiandrino, Annie; Hoehener, Patrick; Sandoz, Alain; Cherain, Yves; Coulet, Eric; Chauvelon, Philippe.
The spatiotemporal structure of wind-driven circulation patterns and associated water exchanges can drive important bio-hydrodynamic interactions in shallow lagoons. The Vaccares lagoon system is a complex shallow hydrosystem located in the central part of the Rhone Delta (France). It is internationally recognized as part of a biosphere reserve within the framework of UNESCO's Man and Biosphere Programme, and as a RAMSAR site. Due to its frequent occurrence in this area, and considering the shallowness of the Vaccares lagoon system, wind is assumed to play a major role in the hydrodynamic and biological processes. In this study, a hydrodynamic model was developed to investigate the structure of wind-driven circulations in the Vaccares lagoon system, to...

An updated assessment of     Symbiodinium     spp. that associate with common scleractinian corals from Moorea (French Polynesia) reveals high diversity among background symbionts and a novel finding of clade B
Provedor de dados: 5
Autores: Rouze, Heloise; Lecellier, Gael J.; Saulnier, Denis; Planes, Serge; Gueguen, Yannick; Wirshing, Herman H.; Berteaux-lecellier, Veronique.
The adaptative bleaching hypothesis (ABH) states that, depending on the symbiotic flexibility of coral hosts (i.e., the ability of corals to “switch” or “shuffle” their algal symbionts), coral bleaching can lead to a change in the composition of their associated Symbiodinium community and, thus, contribute to the coral’s overall survival. In order to determine the flexibility of corals, molecular tools are required to provide accurate species delineations and to detect low levels of coral-associated Symbiodinium. Here, we used highly sensitive quantitative (real-time) PCR (qPCR) technology to analyse five common coral species from Moorea (French Polynesia), previously screened using only traditional molecular methods, to assess the presence of...

Information from these investigations and from other sources were included to compile the present checklist of the marine fishes of the island. A total of 885 species belonging to 150 families was recorded. Nine species are known only from Reunion, indicating endemism of about 1.0%. The most speciose families (Labridae, Gobiidae, Serranidae, and Pomacentridae) were also among the most speciose at the neighbouring Mauritius Island (except gobiids), and, generally, on other islands in the Indian Ocean area (Maldives, Chagos, Madagascar and Christmas Island). The Gobiidae only represented 5.4% of the ichthyofauna, which was...

An updated climatology of surface dimethlysulfide concentrations and emission fluxes in the global ocean
Provedor de dados: 5
Autores: Lana, A.; Bell, T. G.; Simo, R.; Vallina, S. M.; Ballabrera-poy, J.; Kettle, A. J.; Dachs, J.; Bopp, L.; Saltzman, E. S.; Stefels, J.; Johnson, J. E.; Liss, P. S.
The potentially significant role of the biogenic trace gas dimethylsulfide (DMS) in determining the Earth's radiation budget makes it necessary to accurately reproduce seawater DMS distribution and quantify its global flux across the sea/air interface. Following a threefold increase of data (from 15,000 to over 47,000) in the global surface ocean DMS database over the last decade, new global monthly climatologies of surface ocean DMS concentration and sea-to-air emission flux are presented as updates of those constructed 10 years ago. Interpolation/extrapolation techniques were applied to project the discrete concentration data onto a first guess field based on Longhurst's biogeographic provinces. Further objective analysis allowed us to obtain the final...

An Updated Geophysical Model for AMSR-E and SSMIS Brightness Temperature Simulations over Oceans
Provedor de dados: 5
Autores: Zabolotskikh, Elizaveta; Mitnik, Leonid; Chapron, Bertrand.
In this study, we considered the geophysical model for microwave brightness temperature (BT) simulation for the Atmosphere-Ocean System under non-precipitating conditions. The model is presented as a combination of atmospheric absorption and ocean emission models. We validated this model for two satellite instruments-for Advanced Microwave Sounding Radiometer-Earth Observing System (AMSR-E) onboard Aqua satellite and for Special Sensor Microwave Imager/Sounder (SSMIS) onboard F16 satellite of Defense Meteorological Satellite Program (DMSP) series. We compared simulated BT values with satellite BT measurements for different combinations of various water vapor and oxygen absorption models and wind induced ocean emission models. A dataset of clear sky...

The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface-to-bottom ocean biogeochemical data, with an emphasis on seawater inorganic carbon chemistry and related variables determined through chemical analysis of seawater samples. GLODAPv2.2020 is an update of the previous version, GLODAPv2.2019. The major changes are data from 106 new cruises added, extension of time coverage to 2019, and the inclusion of available (also for historical cruises) discrete fugacity of CO2 (fCO2) values in the merged product files. GLODAPv2.2020 now includes measurements from more than 1.2 million water samples from the global oceans collected on 946 cruises. The data for the 12 GLODAP core variables (salinity, oxygen,...

Anaerobic digestion of Ulva sp 3. liquefaction juices extraction by pressing and a technico-economic budget
Provedor de dados: 5
Autores: Morand, Berenice; Briand, X; Charlier, R.
In many countries, the algae of "green tides" are harvested in the fight against pollution. Ulva often represents the main component of the tide, and intensive research has been conducted on the possibility to use the algae as a methanisation substrate. However, methanisation is hampered by various practical obstacles, which requires a compromise between productivity and biological yield.   The process described here calls upon a pre-digestion phase of Ulva which, besides the economy of time and volume of the digestion, makes it possible to obtain a biogas of good quality. The methanisation substrate is the hydrolysis juice collected by draining, followed by pressing. The cake resulting from the pressing process can be used as organic enriching or...

Anaerobic utilization of toluene by marine alpha- and gammaproteobacteria reducing nitrate
Provedor de dados: 5
Autores: Alain, Karine; Harder, Jens; Widdel, Friedrich; Zengler, Karsten.
Aromatic hydrocarbons are among the main constituents of crude oil and represent a major fraction of biogenic hydrocarbons. Anthropogenic influences as well as biological production lead to exposure and accumulation of these toxic chemicals in the water column and sediment of marine environments. The ability to degrade these compounds in situ has been demonstrated for oxygen- and sulphate-respiring marine micro-organisms. However, if and to what extent nitrate-reducing bacteria contribute to the degradation of hydrocarbons in the marine environment and if these organisms are similar to their well-studied freshwater counterparts has not been investigated thoroughly. Here we determine the potential of marine prokaryotes from different sediments of the...

Anaesthesia and gonad sampling in the European flat oyster (Ostrea edulis)
Provedor de dados: 5
Autores: Suquet, Marc; Gonzalez, Ricardo; Lebrun, Luc; Queau, Isabelle; Mingant, Christian; Robert, Rene.
Controlled reproduction of the European flat oyster requires the development of tools adapted to this species, including a practical anaesthesia and gonad sampling protocol to facilitate sex determination and the verification of gametogenesis. Three replicate groups of 10 oysters (mean weight +/- SD: 29.9 +/- 8.5 g) were anaesthetised in 5 L containers using magnesium chloride designed either for laboratory (Flucka (R)) or agricultural (Dead Sea Work (R): DSW) use, at two concentrations (50 or 72 g L-1). No significant differences were observed in the percentages of oysters anaesthetised or subsequent oyster mortality with the different anaesthetics or concentrations, but increasing water temperature from 14.9 to 18.8 degrees C significantly increased the...

Analyse bacteriologique de l'eau par mesure potentiometrique de la reduction de l'acide lipoique
Provedor de dados: 5
Autores: Charriere, G; Jouenne, T; Junter, G.
A simple potentiometric technique to detect and enumerate the bio-indicators of water contamination is described. The technique consists in measuring the redox potential of a specific culture medium saturated with oxygen where bacteria are incubated in presence of lipoic acid (LA). These micro-organisms reduce LA to dihydrolipoic acid, giving rise to an important potential drop in the system. This potentiometric "signal" reveals the presence of active metabolic bacteria in the medium. The major assets of potentiometric measurements in presence of LA lies in the reliability and intelligibility of the results (the redox phenomenon being qualitatively and quantitatively studied), associated to a very simple technology. Futhermore, this technique is perfectly...

Oyster productions represent an important part of the french aquaculture. However, diseases are considered as the first limiting factors for the development of this activity around the world. Two exemples point out this problem for the french flat oyster production: Marteiliosis, the disease of the digestive gland, caused by Marteilia refringens, and Bonamiosis, the hemocytic disease, caused by Bonamia ostreae. This report proposes a bibliography analysis of major results obtained for Bonamiosis studies.

Bio-economic models have not been extensively developed for the shellfish farming sector. However, this type of model could constitute a valuable analysis and assessment tool. Only the potential contribution of this kind of model in our knowledge of the evolution of production systems and marketing are discussed here. These models help comprehend the interactions between the strategies of the different players in the sector and also-on the level of individual businesses-between the shellfish farming sector, as well as the other economic activities that utilise shellfish farming areas, and the type of activity. In particular, it is possible to show the externalities that affect shellfish farming (for example, by revealing the relationships between nutrient...

Autores: Loubersac, Lionel; Viollier, Michel; Lemasson, Claire.
Spectral signatures of the same tropical salt marsh targets, adquired on the ground (Sept 20th 1986) and from altitude (helicopter survey sept 17th 1986) with three looking angles are compared to the SPOT HRV data of sept. 18th 1986 and correlated to some physical properties of the barren salt flats. Those observations give coherent results but, on dense vegetation the satellite response appears under estimated when, on barren flats, it appears over estimated. An atmospheric environmental effect explanation is proposed. Significant correlation between vegetation and brightness and humidity indexes and organic matter of soils are found.

Analyse de descripteurs énergétiques et statistiques de signaux sonar pour la caractérisation des fonds marins
Provedor de dados: 5
Autores: Le Chenadec, Gilles.
Sonar systems own the attractive ability to simultaneously provide a bathymetric map and a sonar image of large insonified seabed areas. Recorded data information, the backscattered energy is well known as an essential clue about the seabed nature and roughness. This PhD thesis lie within a seafloor characterization project using acoustical methods. The objectives are the data exploitation of two sonar systems (a multibeam echosounder and sidescan sonar) ; both operate at a high frequency (around 100 kHz) but their survey geometry is different. Sonar images are first analyzed and reveal artefacts due to geometry of the sonar system and array patterns, leading to difficulties in their geological interpretation. In the context of the sediment discrimination,...

Analyse de données en écologie benthique : utilisation de la méthode de l'analyse de parcimonie
Provedor de dados: 5
Autores: Bellansantini, D; Dauvin, Jc; Bellan, G.
Parsimonious analysis, a method used in cladistics, which considers the coherence of characters, is used to establish the phylogeny of different taxa. Its use in the analysis of ecological and biogeographical data in marine benthic studies remains rare. Application to data collected from ecological or biogeographical works and previously studied by classical analysis demonstrates the potential and the advantages of this method in the study of spatio-temporal marine benthic series.

Bien que défini par la Norme AFNOR (NF V45-056), l'affinage des huîtres C. gigas en claires ostréicoles traditionnelles reste une pratique zootechnique non contrôlée. L'expérimentation 1994 a permis de tester 1) l'effet de la densité d'élevage (2 à 10 huîtres/m2) sur la croissance et la production de C. gigas, 2) la variabilité au sein de la claire de la croissance, et 3) d'évaluer les différentes sources de variabilité des paramètres physico-chimiques et trophiques de la colonne d'eau et de l'interface eau sédiment. Différentes échelles spatio-temporelles de ces variables ont été évaluées variant entre 2 périodes consécutives de emplissage du marais jusqu'au suivi en continu (pas de temps de 5rnn) des paramètres.

For the fourth consecutive year, the fishing returns of the shelly season of the roads of Brest are analyzed. For the black Scallop, principal species currently exploited, the goal is to know the evolution of the fisheries. For the shell St Jacques, season 86-87 saw a light improvement of the captures due to a good recruitment during summer 84. In the first chapter the general conditions of the unfolding of the countryside are treated, in the following are analyzed the captures of black scallop then of shell St Jacques. In appendix the data of effort and production of the other species during the season appear.

Analyse de la structure du système de pêche artisanal guyanais. Introduction à sa dynamique
Provedor de dados: 5
Autores: Blanchard, Fabian; Charuau, Anatole; Rose, Joel; Achoun, Joseph.
Les activités de la petite pêche et de la pêche côtière en Guyane ne sont pas encore assez bien organisées pour permettre un suivi rigoureux. On sait surtout qu'il s'agit d'une activité en baisse et le déclin amorcé au début des années 80 n'a fait que se confirmer dans les années récentes. Alors que le nombre de bateaux pratiquant de façon régulière la petite pêche avoisinait les 150 en 1985, en 1998, la flottille était réduite à 65 unités. Un chiffre fera mieux comprendre cette évolution: dans les années 80, il y a eu jusqu'à 12 tapouilles à Cayenne, alors qu'à la fin 1998, il en restait 4. On peut espérer qu'en 1999, 2 tapouilles supplémentaires et les 3 navires expérimentaux construits par la Région Guyane viendront s'ajouter à cette flottille et...

Provedor de dados: 5
Autores: Rudloff, M.a.; Salles, J.m.
In light of the diminishing wetlands, collective management of these natural areas is becoming a major issue in many countries, particularly in Europe. As a multi-use space, wetlands are coastal areas that are, in practice, subject to conflicts of use among various categories of stakeholders who all consider this natural heritage in terms of their own, and sometimes contradictory, purposes. These conflicts of use can be mediated in several ways. First, wetlands depend on a complex decision process that must integrate diverse rationales. Economic rationales when commercial activities compete; social and political rationales, because natural areas, particularly coastal areas where the human population is particularly dense, are subject to regulations issued...

Analyse de la variabilité spatio-temporelle des populations microalgales côtières observées par le REseau de surveillance du PHYtoplancton et des phycotoxines (REPHY)
Provedor de dados: 5
Autores: Gailhard, Isabelle.
The dynamic of coastal marine microphytoplankton communities is characterized by successions of species assemblages displaying typical schemes of spatio-temporal variability. Numerous studies of phytoplankton spatio-temporal variability have concerned holistic variables such as total biomass or primary production. Such studies deal with the role of primary producers in the global functioning of the pelagic ecosystem, but have little relevance to other problematics. For instance, knowledge of the taxonomic composition of phytoplankton communities and of their spatio-temporal patterns is necessary to understand the mechanisms favouring of the predominance of a precisely identified population within phytoplankton communities. In particular, the identification...

Autores: Sacchi, Jacques; Lespagnol, Patrick.
Suite à l'interdiction communautaire d'utiliser des filets dérivants (définis selon le  règlement CE N° 809/2007) pour la capture des espèces citées dans l'annexe VIII du règlement 1239/98 (modifiant le règlement 894/97) la pratique de cette technique se trouve actuellement limitée à un nombre réduit de métiers utilisés saisonnièrement par la flottille de petite pêche française de Méditerranée, des côtes du Roussillon à celles de Corse. Ces métiers ciblant principalement des sparidés, du bar et quelques petits pélagiques utilisent des filets maillants de surface ou de fond, soit calés au moyen de lignes de mouillage soit en dérive amarrés au navire. Une grande partie des informations sur l’activité de pêche en Méditerranée des filets maillants provient des...

Analyse de l'Etain par Spectrophotometrie d'absortion atomique avec four ectrothermique. Application aux organismes marins
Provedor de dados: 5
Autores: Thibaud, Yves.
The author presents an analysis technique permitting the determination of the tin in the tissues of marine organisms. This technique is only the application of the spectrophotometry of atomic absorption with atomization in the electrothermic oven. After the acid attack of the sample, the solution is put in a graphite oven to atomize the tin selectively and quantitatively. The detection limit obtained, 0,5 mu g/g of the lyophilized flesh is very satisfactory, to show the purport variations in shells from different origins.

Autores: Froidefond, J.m.; Castaing, P.
L'estuaire de la Gironde situé à la limite de la plaine des Landes et des falaises calcaires de Saintonge résulte de la jonction au bec d'Ambès (à 70 km de l'océan) de deux réseaux hydrographique, celui de la Dordogne et celui de la Garonne. De par sa surface et le volume des eaux qu'il draine, l'estuaire joue un rôle important comme voie de communication vers les principaux centres urbains et industriels implantés sur ses rives ou sur celles de ses affluents. n apporte également l'eau et l'énergie nécessaire au développement économique et offre certaines ressources particulières. Sur un autre plan, il constitue au niveau des mécanismes naturels une zone intermédiaire où les eaux de la Garonne et de la Dordogne transitent avant d'aboutir dans les eaux...

Analyse de l'évolution temporelle de communautés macrobenthiques à partir des probabilités de présence des espèces
Provedor de dados: 5
Autores: Mante, C; Durbec, Jp; Dauvin, Jc.
Statistical analysis of long-term changes in marine communities generally involves recourse to multivariate methods. Some of these, such as Correspondence Analysis (CA), are very sensitive to the presence of rare species in the data, whereas other methods, such as Principal Components analysis (PCA) or Multidimensional Scaling (MDS) are only sensitive to the dominant species. Thus, it is necessary to identify rare species. We used an original method of species determination, based on a multinomial scheme and permitting the generalization of the classical presence/absence coding from a probabilistic viewpoint. This selection method was applied to the identification of the different categories of species (rare, intermediate or dominant) that constitute the...

Les Directives Habitats (92/43/EEC) et Oiseaux (79/409/EEC) listent un certain nombre d'espèces et d'habitats marins devant être préservés. Actuellement, la mise en oeuvre de ces Directives se traduit localement par la désignation de sites Natura 2000 en mer. La préservation des habitats et espèces retenus dans ces Directives peut donner lieu à des mesures de gestion particulières, notamment concernant les activités de pêche. Par ailleurs, la modification en cours de l'article L 414-4 du code de l'environnement, prenant en compte la jurisprudence communautaire sur la nécessité d'évaluation des incidences des activités humaines sur l'environnement, introduit la nécessité, à terme, d'évaluer l'impact des engins de pêche sur les habitats et espèces dans le...

Lorsque l'on étudie la flotte de pêche artisanale française, on ne peut qu'être frappé par la grande diversité des navires existants. L'examen des unités, soit construites ces dernières années, soit mises en chantier, soit projetées, dans le cadre de la politique de renouvellement de la flotte artisanale ne laisse apparaître aucune évolution significative dans ce domaine. On peut certes expliquer la très grande variété de navires proposés par différents facteurs : . Le coût des unités de pêche doit s'adapter aux budgets disponibles, très divers, les équipements intervenant de façon non négligeables dans ces coûts. .

A large number of studies on common sole have already been done for years by many research laboratories. This study sought to make a focus on a major nursery on the Atlantic coast, the Pertuis charentais, through the results of eight annual surveys (2005-2012) in late summer (SOLe PERtuis) targeting sole juveniles with a small beam trawl until subtidal zone (&lt;1.50 m). Some of the results obtained in this report confirm previous studies, such as, among others, that more than 80% YOY (G0) occupy muddy or sandy mud bottom at a depth less than 5 m, or that there is a relative correlation between large rainfall in the spring, river flows and abundance of G0 in nursery.   However in the Pertuis Breton this correlation is little expressed by an extension of...

During the years 2008 to 2013 several observations of catches were planned on board of set netters fishing in the bay of Biscay, in the English Channel, in the North sea and in the Mediterranean area (around Corsica). All the observations were done on nets without pingers and they were pooled to provide an average bycatch rate of marine mammals by fleet. Estimates of annual bycatch by using the fishing efforts of the year 2012 were provided by fleet. Harbour porpoise Phocoena phocoena was the most common bycatch in set nets. An average annual estimate of 600 harbour porpoises was obtained for the French fleet; other species recorded in set nets were mainly common dolphin Delphinus delphis, striped dolphin Stenella coeruleoalba and the two species of seals...

Autores: Bebars, Mi; Lasserre, G; Hoai, Tl.
Annually exploited communities from the Nile delta and two nearby lagoons (Manzalah and Edkou) were monitored from 1962 to 1989. The changes in community structure were analysed as a function of two events: fishing pressure growth (motorized fishing vessels) which increased by a factor of 19 between 1952 and 1962; and the construction of the Aswan Dam, which was built between 1965 and 1969, reducing the flow of the Nile by 90 %. Before the construction of the dam, increased sea fishing pressure led to a decline in landings from 33,832 tons in 1962 to 8,522 tons in 1969, but with no structural change in the exploited community. However, following completion of the dam in 1969, the community structure changed and a significant correlation was detected...

Recruitment - the number of young fishes that integrate each year the exploitable stock¿ has a central importance for stock dynamics. The high temporal variability in recruitment is a result of the environmental influence on survival during early life stages. Understanding the determinism of the influence of environment on recruitment remains one of the most important question in fisheries ecology. The present work aimed at answering some general questions about the influence of environment on fish recruitment using a macroecological approach. The study focused on the exploited fish populations of the Northeastern Atlantic. The first chapter of the thesis makes a review of the different methods used to estimate recruitment, compares recruitment estimates...

Analyse des hydrocarbures volatils dans l'eau par entraÎnement gazeux - Application de la technique de Grob
Provedor de dados: 5
Autores: Marchand, Michel; Caprais, Jean-claude.
The analysis of volatile organic substances requires a specifie methodology. We have taken up the Grob's procedure [1]. Enrichment of the volatile trace organics is performed by close-loop gaseous stripping followed by absorption on a microcharcoal filter. The organic substances are eluted from the charcoal by 15 µ of carbon disulfide and analyzed by high resolution gas chromatography. The recovery of the method (trapping from water, desorption from activated charcoal) is determined for different kinds of volatile organic compounds: saturated hydrocarbons (n-C7 to n-C19), aromatic hydrocarbons (benzene, naphtalene and alkylated compounds) and chloro-aromatic hydrocarbons of benzene and naphthalene.

Autores: Davies, Leo.
The Marine strategy Framework Directive (MSFD) aims to reduce impacts on the marine environment in order to achieve or maintain the good ecological status by using ecosystem approach. The conservation of fish population, exploited or not, is one of the objectives. Criterion 3 of the Descriptor 1 „Biodiversity – Fish” and Descriptor 3 “Commercial species” must qualify the ecological state of these components with regard to their demographic characteristics, in addition to other primary criteria. Many size indicators exist, but in the absence of a threshold value to qualify a condition, this criterion was classified as non-operational in the previous assessment cycle. This study aims to analyze the relevance of size indicators for providing information on...

Autores: Coiffec, Gaelle; Duhamel, Erwan; Biseau, Alain; Danzart, Marc.
Since 1993 the yearly amounts of sardine landings for the Bay of Biscay fishing ports have experienced a constant increase (10,000 tonnes in 1993); on that account sardine is the first species landed in the fishing ports of the Bay of Biscay (15,000 tonnes in 2003). It is sold 0.54 € / kg (constant price over ten years) which means a 8,100 k€ turnover in 2003 and the 12th rank in value landed in the fishing ports of Bay of Biscay. Though anchovy landings have decreased over the last ten years, especially since 2001, this species occupies the 3rd rank of the highest landings (7,300 tonnes) of the Atlantic shoreline in 2003.The decrease of anchovy landings over the last ten years may account for the high increase of its constant sale price of 1.5 € / kg from...

This study deals with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : it relies on a survey achieved in july 2001, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers.  The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according to prices and availability of oysters supplies. The duration until marketable size and mean mortalities seem to have increased since a preceding inquiry in 1986.  The main constraint, affecting priorly the south border...

ln the Pertuis charentais shallow area, located between the mainland and the Ré and Oléron islands, marin space is in dispute between the severals stakeholders. The fishing in this area is permitted by a licencing policy and is strongly affected by the space competition. lts future is also uncertain because of the state of the fishing stocks, the new regulations which must be implemented. Given this context, this study aims to assess the evolution and adaptation abilities of the exploitation system in the Pertuis charentais facing the change of the socio-technic context. On board and at port, surveys were carried out. The fishing fleet is made up of old boats, but the fishing is attractive for the fishermen. The enterprise logic functioning as studied and...

This study is focusing on the architecture and recent sedimentary evolution of the Danube channel, the youngest channel-levee system in the Danube deep-sea fan. The study was conducted as part of the BlaSON French-Romanian Project, and combined high-resolution seismic-reflection profiles and chirp profiles with multibeam bathymetry and piston cores. This data set was acquired in 1998 during a joint survey IFREMER-GeoEcoMar of the north-western Black Sea. Previous seismic and acoustic data were also used. The Danube deep-sea fan is a large passive-margin mud-rich fan. Like the other systems of this type (Amazon fan, Mississippi fan or Indus fan) the Danube fan consists of stacked channel-levee systems intercalated with mass-transport deposits. Seismic and...

Fishing power analysis leads to determine a typology of fleet which depends on target species. Three factors are examined : port of origin, engine power and type of trawl. Specific abundance index analysis leads to determine a diagram of principal stages of vital cycle : juvenile, reproductive adult and recovery adult. Then calculs are made in value for all species combined : we obtain thus an economical index by location and season.

SODACAL prawn farm which was set up as a pilot farm for the development of a prawn industry in New Caledonia, saw its production exponentially rise from 1984 to 1992 (to 400 t/year, then experienced a sharp drop in 1993 (250 t/year) which carried on until 1997, and finally rose back to a stabilizing level around 400 t/year until 1999. The study analyses the difficulties observed before and during the drop of production. Among them, mortality outbreaks, other biological perturbations (benthic mat clearing and crab and fish mortality) and focus on the noxious state of the bottom (reduced and smelling sulfide hydrogen). It particularly shows that Syndrome 93 outbreaks could be observed on this farm from 1990. The analysis highlights the particular climatic...

(Not controled OCR) The economic results of artisanal fishing enterprises are investigated through a sample of 300 to 700 artisanal vessels for which account books are available from 1983 to 1986. The use of economic (such as added value) and financial ratios (solvency and financial autonomy) leads to the identification of four groups of firms. A rough classification has been identified from gears used and areas. Over the period, financial rentability and autonomy show obvious damaging that underlines the relevance of a (current) analysis on the impact of public subsidies on the enterprises behaviour.

Analyse des risques pour les mammifères marins liés à l'emploi des méthodes acoustiques en océanographie

Autores: Lurton, Xavier; Antoine, Loic.
The use of acoustical systems in various human activities in the ocean (industry, defence, science) raises the issue of their impact upon marine mammals populations. Several serious accidents linked to the use of naval sonars led the military, industrial and scientific communities to investigate the potential dangers of their own activity.    This report aims at identifying the risks for the cetaceans linked to the use of acoustic and seismic systems currently used for oceanographic science. The analysis proposed here stays within the frame of bibliography synthesis and elementary modelling, and brings no new scientific elements on the topic. An overview of the status of cetacean populations is given first, with a summary of the possible acoustical...

Analyse des stratégies de contrôle dans une pêcherie gérée par l’effort de pêche : le cas de la pêcherie de coquilles Saint-Jacques de la baie de Saint-Brieuc
Provedor de dados: 5
Autores: Le Gallic, Bertrand; Fifas, Spyros; Lesueur, Marie; Roncin, Nicolas; Ropars-collet, Carole.
Since a report by the European Court of Auditor in December 2007, EU officials have been suggesting that the failure of the Common Fisheries Policy (CFP) results from too much non compliance and a weak and inefficient enforcement system. As a result, a stakeholder consultation was organised EU-wide, and a new control regulation has been presented by the European Commission in autumn 2008. The objective of the paper is to discuss the reality and the scope of this assertion in the situation of a French coastal fishery managed through effort control (the Saint-Brieuc scallop fishery). Key outlines of the French control strategy are presented for the first time, based on an extensive work with the key stakeholders (national and regional administrations and...

1. The ASTRODOME research project aims to study the economic aspects of the system of allocation and transmission of shellfish concessions, which is considered as an essential element in the understanding of the occupancy strategies of the coastal maritime space. Two series of questions are highlighted. The first series examines the system from a sectorial development point of view: what are the shellfish farmers' needs that the implementation of a quasi concession market satisfied, and to a larger extent, what is the contribution of the evolution of the system of allocation and transmission of concessions to the evolution of the sector's structure? The second series takes a look at the system from a collective interest point of view: to what extent does...

Cette étude s'inscrit dans le cadre de travaux orientés vers la compréhension des stress du passage en mer. Cette approche s'effectue grâce à des analyses purement zootechniques réalisées par PHILIPPE (1991) et par l'observation des stries de croissance visibles sur les coquilles du naissain de Pecten maximus. Cette étude est tout d'abord axée sur la mise au point d'une méthodologie d'analyse de ces stries. La question est ensuite de cerner l'utilité de ces stries dans une meilleure perception du stress consécutif au passage en mer affectant les juvéniles de coquille Saint-Jacques issus d'écloserie.

The authors have studied the structure of the fishing fleet for artisanal and industrial fisheries and its activities in the harbours of the Atlantic coast: Douarnenez, Concarneau, Lorient, Saint-Nazaire, Nantes, La Rochelle, Bayonne etc. It appears that the decline of the traditional fishery corresponds to the degradation of the stocks, especially the hake and megrim stocks. The industrial fishery supports the consequences of this overfishing while the artisanal trawling fishery showed in 1975 a relative prosperity. In conclusion, it is evident that stock degradation is chiefly caused by fisheries utilizing too narrow meshes. This is not irreversible and it is probable that a sensible widening of the meshes would permit better management of the potential...

Analyse des tendances des séries temporelles de la concentration en azote minéral dissous dans les trois principaux estuaires de la façade Manche-Atlantique
Provedor de dados: 5
Autores: Gailhard, Isabelle.
Estuaries are areas which, from their structure, their fonctioning, and their localisation, are subject to significant contribution of nutrients. One of the objectif of the RNO, the French network for coastal water quality monitoring, is to assess the levels and trends of nutrient concentrations in estuaries. A linear model was used in order to describe and to explain the total dissolved nitrogen concentration evolution in the three most important estuaries on the Chanel-Atlantic front (Seine, Loire and Gironde). As a first step, the selection of a reliable data set was performed. Then total dissolved nitrogen evolution schemes in estuary environment were graphically studied, and allowed a resonable choice of covariables. The salinity played a major role...

Analyse, distribution, production et dégradation d’esters de phtalates (PAEs) en zone côtière méditerranéenne
Provedor de dados: 5
Autores: Paluselli, Andrea.
Phthalic Acid Esters (PAEs) are a group of emerging organic contaminants that have become a serious issue because of their ubiquitous presence on the marine environment worldwide and for the endocrine disrupting effects in animals and humans. However, little is known about their distribution in the Ocean, mainly because of analytical difficulties and the high possibility of ambient sample contamination. Plastic debris in marine environment includes resin pellets, macro- and microplastic fragments, and contains additives such as PAEs that might be released in the aquatic environment in unknown proportion. In our work, we improved an analytical method for the determination of 8 PAEs, at trace levels in marine and fresh waters. In the first part of the...

Analyse du benthos au large du site des Caps. Recherche de l'impact d'une extraction de granulats
Provedor de dados: 5
Autores: Davoult, Dominique; Richard, Alain.
Le site des Caps est une zone littorale bien particulière, bordure française du goulet du Pas-de-Calais, à la fois rétrécissement géographique important entre la France et l'Angleterre, et limite entre la Manche Orientale et le sud de la Mer du Nord. Une zone d'extraction de granulats marins a été exploitée entre 1971 et 1980 au large de ce site. Cette exploitation a été arrêtée en 1982 par arrêté préfectoral pour des raisons d'atteinte à l'environnement et d'entrave à la pêche. La présente étude a pour but de décrire les peuplements au large du site des Caps, englobant le quadrilatère d'exploitation, de faire ressortir leurs caractéristiques. et d'essayer d'apprécier l'impact dû à l'extraction. Deux problèmes majeurs sont soulevés : d'une part, aucune...

Dietary studies of marine species constitute an important key to improve the understanding of its biology and of its role in the ecosystem. Thus, prey-predator relationships structure and determine population dynamics and the trophic network at the ecosystem scale. Among the major study sites, the marine ecosystem is submitted to natural and anthropogenic constraints. In the North-Eastern part of the Atlantic Ocean, the Bay of Biscay is a large open area surrounded South by Spain and East by France. This bay is an historic place of intense fishery activities for which the main small pelagic species targeted are the pilchard, Sardina pilchardus and the anchovy, Engraulis encrasicolus. The aim of this work is to analyze the trophic ecology of these two small...

Des mesures de cuivre total dans les sédiments de quelques estuaires bretons ont été réalisées. Il a été trouvé une relation directe entre le cuivre et la granulométrie, les concentrations les plus élevées correspondant aux granulométries les plus fines. La relation entre le cuivre et la matière organique n'est pas évidente. Il semble que les concentrations en cuivre sont en relation avec le rapport : porcs (sauf petits en lactation) / surface cultivée, dans les cantons où ont été faits les prélèvements.

In addition to the impact on climate change resulting from the use of non renewable resources [1], the depletion of existing fossil fuel sources is inevitable. A major change of strategy is required. This article presents an analysis of a Flax fibre/PLLA biocomposite life cycle compared to common glass fibre reinforced polyester composites from manufacturing to mechanical design and end-of-life. Environmental impacts have been assessed by Standardized method called Life Cycle Analysis (ISO 14044). Flax fibre/PLLA biocomposites manufactured by film stacking have, for similar mass, tensile modulus close to that of Glass/Polyester. Besides being compostable at end of life, biocomposites have been proved to be recyclable which makes it possible to keep the...

Analyse du déclin de la pêche artisanale à St Pierre et Miquelon
Provedor de dados: 5
Autores: Eynaud, P.
Studying the reasons behind the decline in small-scale fisheries at Saint Pierre and Miquelon (SPM) requires assessing this decline. Between 1950 and 1985, the number of vessels utilised in small-scale fisheries dropped by a factor of seven and the mean age of fishers increased by 13 years. Individual catches have nevertheless remained stable and have even increased slightly since 1963. Can it be deduced that the crisis in small-scale fisheries is only due to a problem of fish stocks and the adjustment of the number of fishers to stock availability? Must the causes of decline be sought in the development of industrial fisheries? In the increase in costs? Or in market studies? By placing SPM in its geographical and historical context, these questions take...

Autores: Gilly, B.; Cochet, Y.
The french Guyana sh rimp fishery has grown from the sixties, following the development of US a nd Japanese fleets. The EEZ delimitation in 1977 and the french policy towards promotion of french vessels allowed, since 1980, the emergence of french ship-owners. The paper analyses the recent economie evolution of the enterprises and underlines first the importance of this activity within regional economy, and second its dependance on imported inputs. The french policy leads to an incrcase of the share of the net added value that remains in the depanment, but it also come to a poor financial status of the french ship-owners. The data collected and given in this paper will be used to feed a bio-economic model o f the shrimp fishery.

In the framework of French-Brazil co-operation, the French Institute of research for exploitation of the sea (IFREMER), the State of Bahia and the company Littoral Sul Maricultura have developed a new technique for shrimp farming (Penaeus vannamei) using floating cages. After trials carried out during three years, this technique turns out very interesting from several viewpoints. The growth speed and the survival rate are very good, the negative effects on the environmental quality are weak and local fishermen have proved eager to adopt this technique as a part-time activity. In the same time, a technico-economic analysis, using a computerised simulation tool, as well as a market analysis in the State of Bahia have been carried out in order to assess the...

Clam culture is a shellfish farming activity that has now entered a phase that will determine its future. After the first experimental trials and pilot projects, private investors have set this new aquaculture activity in motion. Today, the progress of clam production is conditioned, in part, on public authorities and financial organisations. On what basis should decisions be made so that appropriate choices are made for the development of clam culture, while respecting other users of coastal areas? This financial and economic study of clam culture seeks to give an overview of current clam farming by analysing operations that have entered the production phase. This approach to productivity of this activity will be done using classical financial analysis...

Analyse et estimation des puissances de pêche
Provedor de dados: 5
Autores: Laurec, Alain.
An analysis of the fishing power concepts leads to a distinction between local fishing power (at a given location). and overall fishing power. Overall fishing power takes into account the ability to detect and quickly exploit rich areas. In order to estimate local fishing power it is necessary to compare the catches of different ships operating in neighbouring areas. Such a comparison performed on two ships will give an estimate of their relative fishing powers. The closer the two ships are, the more reliable will be the estimate. A weighting function must be used, and this function is related to the spatial heterogeneity of the fish density. Such a function is provided by the variogram as defined by Matheron (1965).

Autores: Fifas, Spyros.
The population dynamics is developed upon data on the age-composition of catches collected since 1974 by a sampling technic at two levels (fishing day, vessel). A temporally stratified sampling is carried out. A cohort analysis is realized through these data ; assumptions for the coefficients of natural and indirect fishing mortality are set up. Catchability models for all age groups are fitted. Catchability of the most abundant age groups (2 and 3) is an increasing function of their abundance and of the fishing fleet mean horse power. These functions present a maximum asymptotical value. Their adequation is explained by the adaptations of dredges and by the population sedentary life allowing the concentration of fishing fleet on the most abundant areas. A...

This work presents analysis and prediction of the dispersion of radioelements in the marine environment based on the pulse response theory. The analysis is made on three data sets over the period 1984-1988 : the amounts of gamma-emitting radioelements contained in controlled releases from the nuclear reprocessing plant of La Hague (=signal emission point), and gamma-emitting radionuclide concentrations in sea water at two stations (=signal reception points), situated at 8 and 35 km distance from the release point. Using this data base, the pulse response is determined for each station and for each element. This allows us to estimate the mean delay and the amplitude of the reception signal (i.e. the concentrations of radioelements) and its sensitivity to...

The analysis of the official statistics of commercialised production of oysters (.Crassostrea angutata and Crassostrea gigas ) is achieved from 1866 to 1984 in term of their numbers and weights for the bay of Marennes-Oleron. The number of sanitary labels, multiplied by the mean weight of a crate can also give out the commercialised production   provided it is increased by the bias and decreased by the exterior production of the bay . Thus the production of Portuguese oysters is only 45 000 tons from 1948 to 1957 with a  maximum of 52, 000 tons for respectively 70 000 tons and 280 000 tons for the statistics .

Analyse morpho-tectonique et caractère de la sédimentation au Quaternaire récent sur la plate- forme continentale Pacifique de la Colombie
Provedor de dados: 5
Autores: Pujos, M; Griboulard, R; Latouche, C; Meidinger, P.
The continental shelf is very narrow and steep to the north, and broader to the South. This shelf is structuraly influenced by the Andes. This area is mainly covered with terrigenous deposits, i.e. muds and sands which are recent on the internal shelf and relict on the external shelf. The sediments, supplied by rivers, reflect the intense erosion of the Andean backland. This erosion can only be reduced in situ by the vegetation cover. Clays are the main component of the fine fraction reaching the sea. Three different clay assemblages are observed: 1) an Andean (illite-chlorite) assemblage, reflecting the proximity of the cordillera; 2) a mid-American assemblage (smectite), which supplies the North Pacific Margin through the Choco counter-current; 3) an...

Analyse multivariable des taxocénoses annélidiennes du golfe du morbihan
Provedor de dados: 5
Autores: Chardy, Pierre; Desbruyeres, D.; Laurec, A.
Two initial methods are used to define benthic annelid taxocoenoses within the Morbihan gulf. 139 samples and 83 species are included in the matrix data. Correspondence analysis is shown to be appropriate in the classification of heterogeneous systems. It isolates Mesopsio moorei sand population from winole other samples. General analysis is better appropriate within homogeneous systems, and is able to study populations with regard to production. Results are comparable with those got fromthe whole fauna. In addition, a biogeographic limit is pointed out, within amphicteis gunneri sponge spicule muds. [NOT CONTROLLED OCR]

Analyse néo-institutionnelle de l'investissement dans la biodiversité : choix organisationnels et leurs conséquences sur la restauration des écosystèmes aquatiques
Provedor de dados: 5
Autores: Scemama, Pierre.
L’objectif de ce travail est d’identifier les contraintes économiques à prendre en compte pour encourager l’investissement (public et privé) dans la restauration des écosystèmes aquatiques à partir du prisme de l’économie néo-institutionnelle. Au cours de ce travail nous avons mobilisé des matériaux et des méthodes variés qui nous ont permis d’identifier trois types de contraintes : des contraintes de coûts, des contraintes organisationnelles et des contraintes institutionnelles. La réalisation d’un diagnostic collectif et d’un état de l’art sur les actions de restauration à partir de différentes sources nous a permis d’observer la grande diversité des projets d’investissements dans les écosystèmes aquatiques. Nos résultats montrent que ces projets sont...

Analyse par elements finis d'un catamaran sur coussin d'air en sandwich
Provedor de dados: 5
Autores: Hermundstad, O; Moan, T; Nordal, H.
This paper deals with the structural analysis of transverse frames and bulkheads in sandwich catamarans. Finite element analyses of a frame and a bulkhead have been carried out, and the results are compared to those obtained from a finite element model of the entire craft. The frame and the bulkhead have been analysed with five different boundary conditions. Four idealized load combinations have been applied, and it is demonstrated that transverse frame models can give quite inaccurate results. This is due to the difficulty in deciding the relevant support springs to represent the interaction between the actual frame and the other part of the structure. When designing a new type of vessel, it is recommended to carry out a global finite element analysis...

L'accélération des changements dans tous les domaines, qu'il s'agisse d'environnement, de technologies ou de la vie des sociétés humaines, est une donnée majeure de notre temps. Jusqu'au XIXe siècle, les hommes gardaient une relative maîtrise des révolutions, qu'elles soient techniques (la vapeur, l'électricité, l'atome, ... ) ou sociales (la démocratie, le communisme, etc). A la fin du XXe siècle, la complexité des sociétés humaines, le foisonnement des découvertes scientifiques rapidement exploitées par l'industrie à des fins économiques et l'interdépendance croissante de toutes les activités dans des écosystèmes fragilisés ont conduit les communautés humaines à davantage subir les révolutions: mondialisation d'une économie de plus en plus immatérielle,...

Autores: Latrouite, Daniel; Morizur, Yvon.
French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

Analyse socio-économique de l'exploitation des crevettes en Guyane française
Provedor de dados: 5
Autores: Gilly, Bernard; Cochet, Y.
Shrimp fisheries in French Guyana suffer from the influence of exogenous pressures on shrimp stock. In terms of shrimp stock, the fluctuations in recruitment are very high and determine for the most part the annual production of shrimp boats (Figure 1). Work in progress on the evolution of shrimp stocks suggest that the relatively short shrimp life span (18 months) does not allow a cohort to be exploited over more than one year. In terms of the shrimp boat fleet, there are no alternative outlets for fishing effort.

Autores: Gerbal, Maryse.
Study of soft substrate macrophytobenthos from the mediterranean Thau lagoon has been carried out as a part of the ECOTHAU research program. All soft substrates have been sampled in autumn 1986. Data analysis is based on cartography, total and main species biomass assessment, as well as study of phytobenthos differentiation factors. Vegetation seasonality was analysed from october 1985 to october 1986 in the East area (shellfish breeding zone and "Eaux blanches" lagoon). The hydrologic and topographic characteristics give to vegetation a high specific richness (74 macrophytes on soft substrates and a total of 167 taxa for the lagoon). Compared to those of other mediterranean lagoons, the Thau phytobenthos appears to be original and diversified. This...

Analyse spectrale et statistique vent-vagues des images radar à ouverture synthétique - Application aux données des satellites ERS-1/2
Provedor de dados: 5
Autores: Kerbaol, Vincent.
Le radar à ouverture synthétique (ROS) est le seul instrument à fournir une information directionnelle des vagues grâce à sa haute résolution. Toutefois, l'inversion des spectres 2-D ROS, afin de restituer le spectre de la mer, est rendue difficile par la forte distortion spectrale causée par le filtrage passe-bas dans la direction de déplacement de l'instrument (azimut). Ce filtrage est issu des composantes radiales des mouvements sur la surface qui affectent l'information Doppler nécessaire à la reconstruction de l'image. De plus, le coefficient de rétrodiffusion ?°, permettant d'estimer le vent à l'aide de modèles empiriques, est fréquemment saturé lors de la quantification du signal. Les limitations actuelles démontrent donc la nécessité d'améliorer...

Autores: Menesguen, Alain; Laurec, Alain.
The study of the spatial structure and temporal evolution of several hydrobiological parameters in a flooding docks system provided a good illustration for the analytical power of a methodology dealing with the statistical processing of multivariate timeseries. This technique can be characterized by prior extraction of the trends, treated separately as ordinary multivariate data, and by a consequent multi-spectral analysis of the residual signais. This procedure offers the advantage of clarifying the analysis of the major features of the phenomenon (i.e. the trends) and unmasking the subtle spatio-temporal structure through the residual signais. The application on Le Havre harbour showed a strong enrichment in nutrients and also a plausible but partial...

Autores: Gondeaux, E.
The fishing fleet ana lysis and search of classification criteria are required by the inshore fisheries complexity. For the Mor-Braz fishing fleet, boats ordination and structuration are based on analysis of their seasonnal activity on an annual basis. This is to identify fishing entities or types: Used for their descriptive properties, and linked with cluster analysis, ordination methods appeared as to be powerfull tools. As well as typological studies, studies of the fleet dynamic become easier by these methods. Lastly, the proposed typology which indicates a relation between activity type and individual boats location can be used to improve sampling patterns.

Analyse typologique des activités de pêche de la flottille des côtes-d'Armor
Provedor de dados: 5
Autores: Berthou, Patrick; Chevaillier, P; Jezequel, Michele.
Introduction: Setting up a policy of coastal fisheries management goes through a preliminary stage of understanding the dynamics of the fishing fleets as much as their tactics.  Small fleets, such as those of the Côtes d'Armor, are characterised by: - the boats' home ports are scattered widely, - the heterogeneousness of the types of vessels and fishing gear used,  - the versatility of the fishing units, - the plurispecificity of the exploited resource, - the flexibility of operating strategies, that is, the fishing owners' ability to change occupation. However, this flexibility is limited by the availability of the resource, by the market, by the investments granted (boats, fishing materiel), as well as by "cultural" context and know-how.   This...

Il existe 2 espèces d'huîtres sur nos côtes : Ostrea edulis, l'huître plate et Crassostrea gigas, l'huître creuse. Ces 2 espèces fondent l'essentiel de l'ostréiculture française. Si l'huître creuse a prospéré sur nos côtes depuis 1868 (C.angulata puis par C. gigas à partir de 1973 ), l'huître plate dont la production en 1960 approchait les 15000 à 20000 tonnes a failli disparaître. Deux épizooties ont successivement décimé les bancs d'huîtres plates en Bretagne. Martelia refringens dont la première apparition remonte à 1968 est un parasite de la glande digestive. Un autre parasite, le Bonamia ostreae, apparu en 1979 affecte le système circulatoire de l'huître plate. Cette épizootie a fait chuter la production à moins de 2000 tonnes (Grizel,  1985). Les...

Lors des fouilles archéologiques du Taillis des Coteaux, plus de 791 écailles ont été mises au jour dans une zone attribuée chronologiquement au Magdalénien inférieur. L’origine (animale ou anthropique) des accumulations de poissons dans les sites archéologiques est souvent méconnue. L’application de la sclérochronologie à l’étude de ces restes nous permet non seulement d’avoir une estimation de l’âge du poisson, mais aussi de préciser la période de capture. La connaissance de la saison de mort des individus est un bon indicateur des activités humaines et/ou d’autres prédateurs (carnivores, oiseaux).

Analysing multiple time series and extending significance testing in wavelet analysis
Provedor de dados: 5
Autores: Rouyer, Tristan; Fromentin, Jean-marc; Stenseth, N; Cazelles, B.
In nature, non-stationarity is rather typical, but the number of statistical tools allowing for non-stationarity remains rather limited. Wavelet analysis is such a tool allowing for non-stationarity but the lack of an appropriate test for statistical inference as well as the difficulty to deal with multiple time series are 2 important shortcomings that limits its use in ecology. We present 2 approaches to deal with these shortcomings. First, we used 1/f beta models to test cycles in the wavelet spectrum against a null hypothesis that takes into account the highly autocorrelated nature of ecological time series. To illustrate the approach, we investigated the fluctuations in bluefin tuna trap catches with a set of different null models. The 1/f beta models...

Autores: Petitgas, Pierre; Renard, Didier; Desassis, Nicolas; Huret, Martin; Romagnan, Jean-baptiste; Doray, Mathieu; Woillez, Mathieu; Rivoirard, Jacques.
This paper presents a novel application of the geostatistical multivariate method known as min–max autocorrelation factors (MAFs) for analysing fisheries survey data in a space–time context. The method was used to map essential fish habitats and evaluate the variability in time of their occupancy. Research surveys at sea on marine fish stocks have been undertaken for several decades now. The data are time series of yearly maps of fish density, making it possible to analyse the space–time variability in fish spatial distributions. Space–time models are key to addressing conservation issues requiring the characterization of variability in habitat maps over time. Here, the variability in fisheries survey data series is decomposed in space and time to address...

Autores: Rey, Sonia; Jin, Xingkun; Damsgård, Børge; Begout, Marie-laure; Mackenzie, Simon.
Background Consistent individual differences in behaviour, known as animal personalities, have been demonstrated within and across species. In fish, studies applying an animal personality approach have been used to resolve variation in physiological and molecular data suggesting a linkage, genotype-phenotype, between behaviour and transcriptome regulation. In this study, using three fish species (zebrafish; Danio rerio, Atlantic salmon; Salmo salar and European sea bass; Dicentrarchus labrax), we firstly address whether personality-specific mRNA transcript abundances are transferrable across distantly-related fish species and secondly whether a proactive transcriptome signature is conserved across all three species. Results Previous zebrafish transcriptome...

Autores: Leckler, Fabien; Ardhuin, Fabrice; Peureux, Charles; Benetazzo, Alvise; Bergamasco, Filippo; Dulov, Vladimir.
The energy level and its directional distribution are key observations for understanding the energy balance in the wind-wave spectrum between wind-wave generation, nonlinear interactions, and dissipation. Here, properties of gravity waves are investigated from a fixed platform in the Black Sea, equipped with a stereo video system that resolves waves with frequency f up to 1.4 Hz and wavelengths from 0.6 to 11 m. One representative record is analyzed, corresponding to young wind waves with a peak frequency fp = 0.33 Hz and a wind speed of 13 m s−1. These measurements allow for a separation of the linear waves from the bound second-order harmonics. These harmonics are negligible for frequencies f up to 3 times fp but account for most of the energy at higher...

Autores: Aoki, I; Komatsu, T.
This paper examines the use of a neural network to analyse and predict the winter catch, in the Joban-Boso Seas off the Pacific coast of central Japan, of young Japanese sardine (Sardinops melanostictus) representing the index of recruits in the sardine stock. The supervised learning paradigm, a three-layer network and a back-propagation algorithm were employed in constructing the neural net. A number of biological, hydrographic and climatic factors constituted an input vector, the output being the catch of young sardine. The association of sardine abundance with environmental factors was quantified in the form of the trained neural network, which indicated important associations with the Southern Oscillation Index, with patterns of the Kuroshio and the...

Analysis and visualization of the glass eel behavior (Anguilla anguilla) in the Adour estuary and estimate of its upstream migration speed
Provedor de dados: 5
Autores: Prouzet, Patrick; Odunlami, Marc; Duquesne, Elise; Boussouar, Ahmed.
The studies carried out on the Adour estuary on the migration of glass eels lead to the characterisation of their swimming behavior. Individuals migrate passively with the flood tide current behind the dynamic tide front, and their movements into the water column are linked to the surrounding luminosity and water turbidity. A numerical model was built from observations gathered on glass eel densities during scientific surveys. It uses the outputs of a hydrodynamic model accounting for the variations in the river flow and tide coefficient. It allows the simulation of the displacement of a particle in the longitudinal axis of the estuary. The variation of the vertical movements through the water column takes into account the cloud cover, the moon phases, the...

Analysis of calibrated seafloor backscatter for habitat classification methodology and case study of 158 spots in the Bay of Biscay and Celtic Sea
Provedor de dados: 5
Autores: Fezzani, Ridha; Berger, Laurent.
An automated signal-based method was developed in order to analyse the seafloor backscatter data logged by calibrated multibeam echosounder. The processing consists first in the clustering of each survey sub-area into a small number of homogeneous sediment types, based on the backscatter average level at one or several incidence angles. Second, it uses their local average angular response to extract discriminant descriptors, obtained by fitting the field data to the Generic Seafloor Acoustic Backscatter parametric model. Third, the descriptors are used for seafloor type classification. The method was tested on the multi-year data recorded by a calibrated 90-kHz Simrad ME70 multibeam sonar operated in the Bay of Biscay, France and Celtic Sea, Ireland. It...

Analysis of Clinical Ostreid Herpesvirus 1 (Malacoherpesviridae) Specimens by Sequencing Amplified Fragments from Three Virus Genome Areas
Provedor de dados: 5
Autores: Renault, Tristan; Moreau, Pierrick; Faury, Nicole; Pepin, Jean-francois; Segarra, Amelie; Webb, Stephen.
Although there are a number of ostreid herpesvirus 1 (OsHV-1) variants, it is expected that the true diversity of this virus will be known only after the analysis of significantly more data. To this end, we analyzed 72 OsHV-1 "specimens" collected mainly in France over an 18-year period, from 1993 to 2010. Additional samples were also collected in Ireland, the United States, China, Japan, and New Zealand. Three virus genome regions (open reading frame 4 [ORF4], ORF35, -36, -37, and -38, and ORF42 and -43) were selected for PCR analysis and sequencing. Although ORF4 appeared to be the most polymorphic genome area, distinguishing several genogroups, ORF35, -36, -37, and -38 and ORF42 and -43 also showed variations useful in grouping subpopulations of this...

Analysis of Composite Layup Impact on Hydrodynamic Performances of Sail Yacht Flexible Hydrofoils
Provedor de dados: 5
Autores: Temtching, Vanilla; Augier, Benoit; Dalmas, T.; Fagherazzi, O.; Dumergue, Nicolas.
Composite materials are good candidates for hydrofoil manufacturing, ensuring a good balance between strength and weight. This study investigates experimentally and numerically the inﬂuence of the laminate layup on the hydrodynamic performances of a foil piercing the free surface. Four real scale hydrofoils with a constant chord, geometrically identical with diﬀerent composite lay-up made up in glass or carbon ﬁber, are used for experiments. Mechanical properties of the foils are experimentally obtained and comparisons to numerical approaches calculating composite properties show a good consistency in the different experimental tests and good agreements of numeric and experiments (relative diﬀerence &lt; 10%) when looking at the bending stiﬀness....

Analysis of dissolved gases by headspace sampling gas chromatography with column and detector switching. Preliminary results
Provedor de dados: 5
Autores: Sarradin, Pierre-marie; Caprais, Jean-claude.
This preliminary study presents a new method for the determination of dissolved gases in sea-water. After headspace extraction, gaseous compounds are separated by GC on a dual column adsorption system, The individual species are thereafter eluted to three different detectors (thermal conductivity, flame ionization and FPD) using a second switching valve, The analysis is quantitative for methane and carbon dioxide with limits of determination of 0.1 and 50 mu mol l(-1), respectively, and corresponding standard deviations of 4 and 7%, and has been applied to deep sea hydrothermal samples, Further optimization is necessary to allow the quantitative determination of hydrogen sulfide, nitrogen, oxygen and carbon monoxide.

Autores: Nouguier, Frederic; Mouche, Alexis; Rascle, Nicolas; Chapron, Bertrand; Vandemark, Douglas.
Global colocalized ocean surface measurements using the Global Precipitation Measurement near-nadir dual-frequency Ku- and Ka-band microwave measurements are analyzed and compared. Focusing on the Ka and Ku cross-sections fall-off with incidence angles, the contemporaneous measurements enable to more precisely document differing ocean scattering characteristics for both microwave frequencies. Sensitivity with wind speed and significant wave height is further reported using global comparisons with numerical estimates. As demonstrated, the bifrequency capability can provide direct means to efficiently separate short-scale wave contributions, between mean squared slope and curvature characteristics, and to further gain valuable insights concerning near-nadir...

Analysis of ERS-1/2 synthetic aperture radar wave mode imagettes
Provedor de dados: 5
Autores: Kerbaol, Vincent; Chapron, Bertrand; Vachon, Paris W.
The European Space Agency (ESA) ERS-1 and ERS-2 C band VV polarization active microwave instrument (AMI) offers the unique ability to combine interlaced wind scatterometer and high-resolution synthetic aperture radar (SAR) wave mode imagettes. In this study, more than 2000 imagettes were considered. Each imagette has been statistically analyzed in comparison with normalized radar cross-section (NRCS) measurements from the scatterometer mode. During ti lt ERS-1 AMI wave mode mission the incidence angle of the imagette center was modified from roughly 19.9 degrees to 23.5 degrees. Using ERS-1 and ERS-2 NRCS, calibration has thus been completed for both configurations, which allows a better characterization of some signal data saturation effects. However,...

Autores: Aldebert, Yvonne; Recasens, Laura; Lleonart, Jordi.
The hake of the Gulf of Lions is the most important target species of the demersal fishery. It is exploited by four types of gear (two trawls, gillnet and longline) used by two countries (France and Spain). Some analyses of its dynamics, based on 19 88 length frequency data by gear, have been performed. These analyses consisted in a VPA (Virtual Population Analysis). phis a Y/R (Yield per Recruit analysis) carried out on two parameter scenarios by sex, under a steady state hypothesis (with constant recruitment). Some estimates of biomass and exploitation level were obtained, and sensitivity to the biological parameters and interaction between types of gear were studied. As a main conclusion, it can be seen that the types of gear fishing mainly small...

Autores: Gagnaire, Pierre-alexandre; Lamy, Jean-baptiste; Cornette, Florence; Heurtebise, Serge; Degremont, Lionel; Flahauw, Emilie; Boudry, Pierre; Bierne, Nicolas; Lapegue, Sylvie.
The Pacific cupped oyster is genetically subdivided into two sister taxa, Crassostrea gigas and C. angulata, which are in contact in the north-western Pacific. The nature and origin of their genetic and taxonomic differentiation remains controversial due the lack of known reproductive barriers and the high degree of morphologic similarity. In particular, whether the presence of ecological and/or intrinsic isolating mechanisms contributes to species divergence is unknown. The recent co-introduction of both taxa into Europe offers a unique opportunity to test how genetic differentiation is maintained under new environmental and demographic conditions. We generated a pseudo-chromosome assembly of the Pacific oyster genome using a combination of BAC-end...

Analysis of global surface ocean alkalinity to determine controlling processes
Provedor de dados: 5
Autores: Fry, Claudia H.; Tyrrell, Toby; Hain, Mathis P.; Bates, Nicholas R.; Achterberg, Eric P.
The export of calcium carbonate (CaCO3) from the surface ocean is poorly constrained. A better understanding of the magnitude and spatial distribution of this flux would improve our knowledge of the ocean carbon cycle and marine biogeochemistry. Here, we investigate controls over the spatial distribution of total alkalinity in the surface global ocean and produce a tracer for CaCO3 cycling. We took surface ocean bottle data for total alkalinity from global databases (GLODAP, CARINA, PACIFICA) and subtracted the effects of several processes: evaporation and precipitation, river discharge, and nutrient uptake and remineralization. The remaining variation in alkalinity exhibits a robust and coherent pattern including features of large amplitude and spatial...

Analysis of hemocyte parameters in Pacific oysters, Crassostrea gigas, reared in the field — Comparison of hatchery diploids and diploids from natural beds
Provedor de dados: 5
Autores: Gagnaire, Beatrice; Soletchnik, Patrick; Faury, Nicole; Kerdudou, Nolwenn; Le Moine, Olivier; Renault, Tristan.
Internal defence mechanisms of bivalves include the hemocytes which assume several functions. Relationships exist between environmental factors, physiological state of oysters, defence system and pathogens. Hatchery oysters are more and more produced and reared in the field. The characteristics and particularly the defence system of these animals are poorly documented. In this context, two field trials were carried out from May to September 2002 and from April to July 2003 in order to monitor hemocyte parameters of diploid oysters from natural beds and hatchery-produced diploid oysters using flow cytometry. Several hemocyte parameters (cell mortality, granulocyte percentage, phagocytosis, esterase and peroxidase activities) were monitored. For both oyster...

This study deals with the use of a multivariate analysis method in order to understand the functioning of the Bizerte lagoon ecosystem. A set of hydrobiological parameters was collected during 10 monthly campaigns in 2004. A variant of the EOF (Empirical Orthogonal Function) technique is used to examine hydrobiological variability modes in this lagoon. The permanent features characterising the lagoon are obtained by applying the EOF technique to data after removing the annual cycle. Two major modes were obtained. The first one shows a contrast between the northern sector of the lagoon, influenced by the Mediterranean Sea, and the southern one influenced by continental waters. This mode is mostly prominent for temperature and salinity. The second mode shows...

Analysis of hydrodynamics of a moving trawl codend and its fluttering motions in flume tank
Provedor de dados: 5
Autores: Druault, Philippe; Germain, Gregory.
The coupled dynamics of the codend fluttering motion and its hydrodynamics behavior are investigated based on PIV measurements carried out around a 1/10 scaled model codend. The mean wake flow characteristics are firstly analyzed demonstrating the great effect of the codend motion. The differences in flow contour between fluttering motion and no-fluttering codend are highlighted by analyzing the classical mean characteristics of a body wake flow. In presence of fluttering motion, the classical results are recovered only if one considers the vertical extent of the codends oscillations as a reference length scale. Secondly, the frequency content of codend oscillations is analyzed and it is linked to the physical mechanisms. It is observed that the motion of...

Analysis of hydrogen and methane in seawater by “Headspace” method: Determination at trace level with an automatic headspace sampler
Provedor de dados: 5
Autores: Donval, Jean-pierre; Guyader, Vivien.
“Headspace” technique is one of the methods for the onboard measurement of hydrogen (H2) and methane (CH4) in deep seawater. Based on the principle of an automatic headspace commercial sampler, a specific device has been developed to automatically inject gas samples from 300 ml syringes (gas phase in equilibrium with seawater). As valves, micro pump, oven and detector are independent, a gas chromatograph is not necessary allowing a reduction of the weight and dimensions of the analytical system. The different steps from seawater sampling to gas injection are described. Accuracy of the method is checked by a comparison with the “purge and trap” technique. The detection limit is estimated to 0.3 nM for hydrogen and 0.1 nM for methane which is close to the...

esting laboratories are more and more concerned with the characterization of their measurement processes. In particular, the standard ISO 17025[2] requires the accredited laboratories to participate to interlaboratory comparisons to evaluate their proficiency to realize the measurement. Different statistical methods are available to exploit the results of this type of comparisons. In our study, first we have evaluated the reference value and the proficiency standard deviation with ISO 5725-2 standard [1] and in second part the calculation of statistical indicator Z-score with ISO13528 [5] standard to assess of proficiency of laboratory with the first estimated parameters.

The ingestion of 8 algal species by oyster larvae (Crassostrea gigas Thunberg, 1793) was measured by flow cytometry (FCM). In a preliminary experiment, cell size (estimated by light scatter) and chlorophyll fluorescence of 30 algal species were evaluated to select those species which could be mixed together and still be easily discriminated by FCM. Grazing experiments were carried out over 48 h with 6 and 15-day old larvae fed on 3 algal mixtures, each containing 3 different algal species. The concentration of each species was estimated at 0, 6, 12, 24 and 48 h by FCM. Grazing pressure on a given algal species was dependent upon the age of the larvae, the time of the day and the composition of the mixture. Grazing rates of older larvae were about twice...

Analysis of light hydrocarbons in marine sediments by headspace technique: Optimization using design of experiments
Provedor de dados: 5
Autores: Donval, Jean-pierre; Charlou, Jean-luc; Lucas, L.
Headspace technique is a common method to analyze light hydrocarbons in deep marine sediments. The use of an automatic headspace sampler instead of a manual injection is the guarantee for a better repeatability and furthermore it is less time consuming. But to increase the sensitivity and therefore, to achieve a better detection limit, it is necessary to optimize the automatic headspace sampler parameters. The theory of design of experiments was applied here by studying them. As a response, methane, which is an important gas in marine sediments, was chosen for its short analysis time. Regarding the parameters for automatic headspace sampler, eight variables were selected and then, a screening of them was carried out with a fractional factorial design to...

Analysis of mixed-sediment consolidation experiments
Provedor de dados: 5
Autores: Grasso, Florent; Le Hir, Pierre; Bassoullet, Philippe.
Estuarine sediment transport models require that a time variation of erodibility due to consolidation be taken into account. If numerical modelling of mud sedimentation and consolidation is currently satisfactory, simulation of mud-sand mixture consolidation is more problematical. This is partly due to mixed-sediment processes, as hindered settling and segregation, not well understood yet. Hence, based on extensive settling columns experiments, the aim of this study is to improve our understanding of mud-sand mixture consolidation for varying concentrations (54 to 600 kg/m3) and large sand contents (15 to 80%). Firstly, we observed that for a given initial mass concentration and sand content the final consolidation appeared independent from the initial...

Analysis of random nonlinear water waves: the Stokes-Woodward technique
Provedor de dados: 5
Autores: Elfouhaily, Tanos; Joelson, Maminirina; Guignard, Stéphan; Branger, Hubert; Thompson, Donald; Chapron, Bertrand; Vandemark, Douglas.
A generalization of the Woodward's theorem is applied to the case of random signals jointly modulated in amplitude and frequency. This yields the signal spectrum and a rather robust estimate of the bispectrum. Furthermore, higher order statistics that quantify the amount of energy in the signal due to nonlinearities, e.g., wave-wave interaction in the case of water waves, can be inferred. Considering laboratory wind generated water waves, comparisons between the presented generalization and more standard techniques allow to extract the spectral energy due to nonlinear wave-wave interactions. It is shown that our analysis extends the domain of standard spectral estimation techniques from narrow-band to broad-band processes.

Analysis of riverine suspended particulate matter fluxes (Gulf of Lion, Mediterranean Sea) using a synergy of ocean color observations with a 3-D hydrodynamic sediment transport model
Provedor de dados: 5
Autores: Le Fouest, Vincent; Chami, Malik; Verney, Romaric.
The export of riverine suspended particulate matter (SPM) in the coastal ocean has major implications for the biogeochemical cycles. In the Mediterranean Sea (France), the Rhone River inputs of SPM into the Gulf of Lion (GoL) are highly variable in time, which severely impedes the assessment of SPM fluxes. The objectives of this study are (i) to investigate the prediction of the land-to-ocean flux of SPM using the complementarity (i.e., synergy) between a hydrodynamic sediment transport model and satellite observations, and (ii) to analyze the spatial distribution of the SPM export. An original approach that combines the MARS-3D model with satellite ocean color data is proposed. Satellite-derived SPM and light penetration depth are used to initialize...

Analysis of salinity measurements near islands on the French continental shelf of the Bay of Biscay
Provedor de dados: 5
Autores: Lazure, Pascal; Jegou, Anne-marie; Kerdreux, Michel.
The Bay of Biscay is characterised by large fresh water inputs from two major rivers, the Loire and the Gironde, with a mean discharge of about 900 m(3)/s. To describe the spatial and temporal variability of the Loire and Gironde plumes, continuous salinity measurements were made at 4 locations on French coastal islands over periods lasting at least two years. These islands are located at a distance from the large local gradients linked to local inputs. Whereas sea surface salinity in the centre of the Bay of Biscay is 35.6, salinities at the coast vary between about 35 in summer to occasionally less than 30 in late winter or in spring. Minimum salinities do not occur at the same time along the coast, indicating a strong spatial gradient. Near the Loire...

Analysis of seafloor backscatter strength dependence on the survey azimuth using multibeam echosounder data
Provedor de dados: 5
Autores: Lurton, Xavier; Eleftherakis, Dimitrios; Augustin, Jean-marie.
The sediment backscatter strength measured by multibeam echosounders is a key feature for seafloor mapping either qualitative (image mosaics) or quantitative (extraction of classifying features). An important phenomenon, often underestimated, is the dependence of the backscatter level on the azimuth angle imposed by the survey line directions: strong level differences at varying azimuth can be observed in case of organized roughness of the seabed, usually caused by tide currents over sandy sediments. This paper presents a number of experimental results obtained from shallow-water cruises using a 300-kHz multibeam echosounder and specially dedicated to the study of this azimuthal effect, with a specific configuration of the survey strategy involving a...

The Manila clam presents a large polymorphism for shell colours and patterns. No experiment has been conducted to study the determinism of such a polymorphism which has been well known for a long time. The aim of this study was firstly to determine the genetic variation for shell colour and secondly to produce some homozygous lines for the shell colouring. These lines could then be used as controls for laboratory experiments. The colouring is defined by three characters: asymmetry, ornamentation and hue. Clams with asymmetrical colouring are not fully pigmented, except for a posterior band on the left valve. Clams with symmetrical colouring are fully pigmented on the two valves. Four cross series were conducted between the different characters: Asymmetry...

Autores: Sultan, Nabil; Gaudin, Mathieu; Berne, Serge; Canals, Miquel; Urgeles, Roger; Lafuerza, Sara.
To improve understanding of evolution of submarine canyons, a three-dimensional slope-stability model is applied to Bourcart Canyon in the western Gulf of Lions in the Mediterranean Sea. The model builds on previous work by Chen and others, and it uses the upper bound theorem of plasticity to calculate the factor of safety of a kinematically admissible failing mass. Examples of three-dimensional failure surfaces documented in the literature were used to test the model formulation. Model application to Bourcart Canyon employed the results of a detailed stratigraphic analyses based on data acquired by swath bathymetry, sub-bottom profiling, high-resolution seismic reflection surveys, and piston coring. The sediment layers were also characterized using...

Analysis of specific water masses transports in the Western Mediterranean in the MEDRYS1V2 twenty-one-year reanalysis
Provedor de dados: 5
Autores: Barral, Quentin-boris; Zakardjan, Bruno; Dumas, Franck; Garreau, Pierre; Beuvier, Jonathan.
We present an analysis of specific water masses fluxes in the Western Mediterranean Sea issued from a twenty years (1992-2013) reanalysis (MEDRYS1V2). Water masses are identified on the base of salinity and potential density properties and computes; the fractions of each water mass involved in total flux are computed under the hypothesis assumptions of mixing lines schemes. It was first designed in order to avoid rough truncations between water masses on the T-S diagram when using fixed thermo-haline properties thresholds. The method does not use the temperature marker due to its high seasonal variability in near surface waters (0-200 m) and we consider that potential density is a better marker to discriminate deep and intermediate water masses.

We implement a spatially aggregated tag-attrition model to analyse the results of an albacore tagging experiment conducted in the Bay of Biscay from 1988 to 1991. The model predicts probabilities of the possible fates of tagged fish and the tags that they carry. The model includes several parameters consisting of catchabilities by fleets involved in recaptures and a combination of natural mortality plus emigration from the study area. Model fitting is carried out by finding the maximum of a multinomial likelihood function. Effect of reporting rate values on the estimations are evaluated and several hypothesis on the pre-mixing period of the tagged fish...

Analysis of the black-chinned tilapia Sarotherodon melanotheron heudelotii reproducing under a wide range of salinities: from RNA-seq to candidate genes
Provedor de dados: 5

The black-chinned tilapia Sarotherodon melanotheron heudelotii is an ecologically appealing model as it shows exceptional adaptive capacities, especially with regard to salinity. In spite of this, this species is devoid of genomic resources, which impedes the understanding of such remarkable features. De novo assembly of transcript sequences produced by next-generation sequencing technologies offers a rapid approach to obtain expressed gene sequences for non-model organisms. It also facilitates the development of quantitative real-time PCR (qPCR) assays for analysing gene expression under different environmental conditions. Nevertheless, obtaining accurate and reliable qPCR results from such data requires a number of validations prior to interpretation....

Analysis of the first genome of a hyperthermophilic marine virus-like particle, PAV1, isolated from Pyrococcus abyssi
Provedor de dados: 5
Autores: Geslin, Claire; Gaillard, Melusine; Flament, Didier; Rouault, Karen; Le Romancer, Marc; Prieur, Daniel; Erauso, Gael.
Only one virus-like particle (VLP) has been reported from hyperthermophilic Euryarchaeotes. This VLP, named PAV1 is shaped like a lemon and was isolated from a strain of "Pyrococcus abyssi," a deep-sea isolate. Its genome consists of a double-stranded circular DNA of 18 kb which is also present at a high copy number (60 per chromosome) free within the host cytoplasm but is not integrated into the host chromosome. Here, we report the results of complete analysis of the PAV1 genome. All the 25 predicted genes, except 3, are located on one DNA strand. A transcription map has been made by using a reverse transcription-PCR assay. All the identified open reading frames (ORFs) are transcribed. The most significant similarities relate to four ORFs. ORF 180a shows...

Analysis of the genetic structure and life history of albacore tuna in terms of diversity, abundance and migratory range at the spatial and time scales: Project GERMON (GEnetic stRucture and Migration Of albacore tuNa)
Provedor de dados: 5
Autores: Nikolic, Natacha; Bourjea, Jerome.
Tunas are important commercial species that represent a share of about 8 percent of total fish exports. In 2010, the total catch of tuna in three oceans was about 6.6 million tons, 4.3 million tons for the most marketed species, a level roughly stable since 2002 (FAO 2012). Among these tuna species, there are in descending order of capture: skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), bigeye tuna (Thunnus obesus), albacore tuna (Thunnus alalunga) and bluefin tuna (Thunnus thynnus). Overall, the biology of albacore stock in the Indian Ocean is not well known and there is relatively little new recent information on albacore stocks. Albacore life history characteristics, including a relatively late maturity, long life and sexual...

Dinoflagellates are one of the most abundant and functionally diverse groups of eukaryotes. Despite an overall scarcity of genomic information for dinoflagellates, constantly emerging high-throughput sequencing resources can be used to characterize and compare these organisms. We assembled de novo and processed 46 dinoflagellate transcriptomes and used a sequence similarity network (SSN) to compare the underlying genomic basis of functional features within the group. This approach constitutes the most comprehensive picture to date of the genomic potential of dinoflagellates. A core-predicted proteome composed of 252 connected components (CCs) of putative conserved protein domains (pCDs) was identified. Of these, 206 were novel and 16 lacked any functional...

Analysis of the Holocene climate variability using a data assimilation method in the model LOVECLIM
Provedor de dados: 5
Autores: Mairesse, Aurélien.
The study of past climates and of mechanisms that have influenced their evolution is the key to anticipate the future climate changes. This doctoral thesis focusses on the Holocene climate, the ongoing interglacial, that starts about 11,700 years ago. The current paleoclimate knowledge is based on the one hand, on the climate models results and, on the other hand, on the reconstruction of physical variables derived from climate archives as the ice cores, the marine cores or the pollens for instance. These two types of information are complementary. Here we have combined them to obtain reconstructions of past climates using data assimilation. This technique is standard in many disciplines but not yet in paleoclimatology. The data assimilation method applied...

Analysis of the Influence of Hydrostatic Stress on the Behaviour of an Adhesive in a Bonded Assembly
Provedor de dados: 5
Autores: Cognard, J. Y.; Creac'Hcadec, R.; Maurice, J.; Davies, Peter; Peleau, Michel; Da Silva, L. F. M.
Generally, adhesives are viscoelastic-plastic materials, for which the development of viscosity and plasticity varies depending on the type of adhesive and the stress state. Various models exist to represent the yield surface, or the so-called elastic limit, taking into account the two stress invariants, hydrostatic stress and von Mises equivalent stress. Moreover, to develop precise pressure-dependent constitutive models, it is necessary to have a large experimental database in order to accurately represent the adhesive strains which are strongly dependent on the tensile-shear loading combination. Under quasi-static loadings, for a given strain rate range viscous effects can be neglected, but only a few experimental results are available to model the...

Autores: Arnaud, N.; Creac'Hcadec, R.; Cognard, J. Y.; Davies, Peter; Le Gac, Pierre-yves.
The objective of the study is to identify the 3D behaviour of an adhesive in an assembly, and to take into account the effect of ageing in a marine environment. To that end, three different tests were employed. Gravimetric analyses were used to determine the water diffusion kinetics in the adhesive. Bulk tensile tests were performed to highlight the effects of humid ageing on the adhesive behaviour. Modified Arcan tests were performed for several ageing times to obtain the experimental database which was necessary to identify constitutive models. A Mahnken-Schlimmer type model was determined for the unaged state according to a procedure developed in a previous study. This identification used inverse techniques. It was based on the unaged modified Arcan...

Analysis of the nonlinear behavior of adhesives in bonded assemblies - Comparison of TAST and Arcan tests
Provedor de dados: 5
Autores: Cognard, J; Creac' Hcadec, R; Sohier, L; Davies, Peter.
This paper describes a study in which the shear behavior of a structural epoxy adhesive has been measured using the standard thick adherend shear test (TAST) specimen and a modified Arcan test A. numerical study of the TAST test taking into account the nonlinear behavior of the adhesive and the finite deformations of the adhesive joint, shows that there is a localization of plastic zones close to the adhesive-substrate interface near the free edge of the adhesive. Experimental tests carried out with steel and aluminum substrates and with various adhesives also show that failure initiates in this region. These edge effects in the TAST fixture can lead to an incorrect analysis of the behavior of the adhesive (for instance, underestimation of the shear stress...

Analysis of the potential impact of several management measures for eastern Atlantic bluefin tuna on the basis of yield per recruit
Provedor de dados: 5
Autores: Arrizabalaga, Haritz; Restrepo, Victor; Fromentin, Jean-marc; Ortiz De Urbina, J M.
A standard yield per recruit (YPR) analysis is used to analyse the effects of minimum size regulations and time area closures on bluefin tuna from the eastern stock (east Atlantic and Mediterranean). Analyses were based on a fishing mortality vector computed over the period 1990-1994 for which data were more reliable and VPA (performed during the 2002 stock assessment) showed a relatively good convergence. This fishing mortality vector was modified according to some combinations of minimum size regulations and time area closures. It is concluded that: (i) PSmed is the main contributor to catch at age in the range of ages 1-13; (ii) The minimum size regulations considered would increase the YPR more than the time area closures, but these would enhance SPR...

Analysis of the SAR imaging process of the ocean surface using Volterra models

Autores: Le Caillec, Jm; Garello, R; Chapron, Bertrand.
In this paper, the synthetic aperture radar (SAR) process of the ocean surface mapping is studied using a decomposition based on a Volterra model. By a mathematical expansion of the complex exponential of the complete SAR transform, these models decompose the nonlinear distortion mechanisms of the SAR spectrum over different spectra of polynomial interactions. Thus, they offer an alternative modeling (to the exact SAR transform) giving a theoretical separation between the SAR Fourier components linearly derived from the sea surface elevation and the artifacts created by nonlinearities of. the SAR mapping of the. ocean surface. The main results of this paper consist of the systematic assessment of such an approximation of the ocean surface SAR imaging...

Analysis of time series of planktonic communities in the Adriatic Sea: Distinguishing between natural and man-induced changes
Provedor de dados: 5
Autores: Solic, M; Krstulovic, N; Marasovic, I; Baranovic, A; Pucherpetkovic, T; Vucetic, T.
Time series (&gt; 20 years) of bacterioplankton, phytoplankton and zooplankton abundances and of phytoplankton production in the Adriatic Sea were analysed. Multivariate methods were used to extract the main patterns of year-to-year changes in abundances (Principal Component Analysis), and to discriminate between years and sites (Multidimensional Scaling). Increasing long-term trends were established for planktonic abundances and phytoplankton production in both coastal and open sea areas, presumably as a result of eutrophication processes. In the open sea, natural factors (water exchange between the Mediterranean and Adriatic Seas, and temperature) were dominant in controlling year-to-year fluctuations of plankton. On the other hand, long-term...

Autores: Omnes, Marie-helene; Normant, Yvon; Suquet, Marc; Fauvel, Christian.
Rearing turbot (Scophthalmus maximus) reaches the commercial scale. With the hatchery output increasing, more attention needs to be focussed on broodstocks performance both in terms of quantity and viability of eggs. The techniques of shifting the environmental conditions allow a production of eggs all year round. However, egg quality tends to be highly variable. This paper examines over a two-year period, the improvement in egg quality and its consequences on the production of larvae by a strict management of spawners.

Analytical linear modelization of a buckled undulating membrane tidal energy converter
Provedor de dados: 5
Autores: Trasch, Martin; Deporte, Astrid; Delacroix, Sylvain; Germain, Gregory; Drevet, Jean-baptiste.
This paper presents an analytical linear model developed to study the behaviour of a buckled membrane tidal energy converter. The Euler beam theory and the elongated body theory are used for the fluid structure interaction formulation. The effect of electromechanical converters used to convert the undulating motion into electrical energy is reproduced by adding a term equivalent to viscous material damping. The influence of compression force, flaps and hanging conditions is studied, as well as the effects of simulated power take-off through internal damping. The system's behaviour is characterized by undulating mode, critical flow velocity, motion frequency and amplitude. The model shows good agreement in terms of frequency and satisfactory results for the...

Potential ways to address the issues that relate to the techniques for analyzing food and environmental samples for the presence of enteric viruses are discussed. It is not the authors' remit to produce or recommend standard or reference methods but to address specific issues in the analytical procedures. Foods of primary importance are bivalve molluscs, particularly, oysters, clams, and mussels; salad crops such as lettuce, green onions and other greens; and soft fruits such as raspberries and strawberries. All types of water, not only drinking water but also recreational water (fresh, marine, and swimming pool), river water (irrigation water), raw and treated sewage are potential vehicles for virus transmission.

Analytical modeling of synthetic fiber ropes. Part II: A linear elastic model for 1+6 fibrous structures

Autores: Ghoreishi, Seyed Reza; Davies, Peter; Cartraud, Patrice; Messager, Tanguy.
In part I of this study it was shown that, to model synthetic fiber ropes, two scale transition models can be used in sequence. The first model (continuum model) has been presented in the part I and the present paper examines the behavior of a fibrous structure consisting of 6 helicoidal strands around a central core (1 + 6 structure). An analytical model will be presented which enables the global elastic behavior of such a cable under tension-torsion loading to be predicted. In this model, first, the core and the strands are described as Kirchhoff-Love beams and then the traction-torsion coupling behavior is taken into account for both of them. By modeling the contact conditions between the strands and the core, with certain assumptions, it is possible to...

Autores: Ghoreishi, Seyed Reza; Cartraud, Patrice; Davies, Peter; Messager, Tanguy.
Synthetic fiber ropes are characterized by a very complex architecture and a hierarchical structure. Considering the fiber rope architecture, to pass from fiber to rope structure behavior, two scale transition models are necessary, used in sequence: one is devoted to an assembly of a large number of twisted components (multilayered), whereas the second is suitable for a structure with a central straight core and six helical wires (1 + 6). The part I of this paper first describes the development of a model for the static behavior of a fibrous structure with a large number of twisted components. Tests were then performed on two different structures subjected to axial loads. Using the model presented here the axial stiffness of the structures has been...

On-chip sine-wave signal generation is widely covered by literature for Built-In-Self Test (BIST) or biosensor applications. The objective is to generate pure and robust sinewave signal with minimal hardware resources. An attractive solution consists in combining several digital signals to built this analog sine-wave. The objective of this paper is to give an analytical study of various potential solutions based on digitalbased approaches. Thanks to this study, we prove that technique consisting in setting the phase shifts and various amplitude values of the square-wave signals is the most efficient approach. Moreover, this study allows the selection of the best solution in terms of parameters of the square-wave signals to cancel loworder harmonics of the...

Analytical Techniques for the Doppler Signature of Sea Surfaces in the Microwave Regime-I: Linear Surfaces
Provedor de dados: 5
Autores: Nouguier, Frederic; Guerin, Charles-antoine; Soriano, Gabriel.
This paper is the first in a series of two papers on the use of combined improved hydrodynamic and electromagnetic analytical models for the simulation of the ocean Doppler spectrum at microwave frequencies. Under a linear assumption for the sea surface, we derive statistical expression for the main Doppler characteristics according to asymptotic scattering models. We consider classical models such as the Kirchhoff approximation and the two-scale model, as well as the more recent weighted curvature approximation (WCA). We recover two salient features of Doppler signature in the microwave regime. First, the Doppler characteristics are very sensitive to polarization, with higher mean Doppler shift in horizontal polarization. This is correctly rendered by the...

This paper extends the results of a previous work by combining hydrodynamic and electromagnetic analytical models for the simulation of the ocean Doppler spectrum at microwave frequencies. We consider weakly nonlinear sea surfaces after the choppy wave model and incorporate them in classical and unified scattering models, namely, the Kirchhoff and weighted curvature approximations. We show that statistical expressions can be obtained for the Doppler spectrum in a way similar to the case of linear surfaces. As expected, the nonlinear nature of the sea surface dramatically impacts the Doppler spectrum at moderate to large incidence angles, with a shift of the central frequency and a broadening of the spectrum. Monte Carlo comparisons are performed with the...

Jellyfish outbreaks and their consequences appear to be on the increase around the world, and are becoming particularly relevant in the Mediterranean. No previous studies have quantified tourism losses caused by jellyfish outbreaks. We used a stated-choice questionnaire and a Random Utility Model to estimate the amount of time respondents would be willing to add to their journey, in terms of reported extra travel time, in order to reduce the risk of encountering jellyfish blooms in the Catalan coast. The estimation results indicated that the respondents were willing to spend on average an additional 23.8% of their travel time to enjoy beach recreation in areas with a lower risk of jellyfish blooms.

Autores: Shakun, Jeremy D.
This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns the origin of Pacific decadal variability (PDV). This issue is addressed by calculating the Southern Hemisphere equivalent of the Pacific Decadal Oscillation (PDO) index from Pacific sea surface temperature (SST) anomalies over the 20th century, which is found to be similar to its Northern Hemisphere counterpart. The Northern and Southern PDO indices both exhibit pronounced seasonality in autocorrelation with interannual...

Market position and its evolution were analysed in nine key fish and cephalopod species subject to long-term changes, using the Bay of Biscay fisheries as a case study. Although such long term changes have already been documented, and in some cases shown to be related to the impacts of fishing, changes in the physical environment, or both, relatively little work has been devoted to their potential consequences in economic terms. The nature and extent of these consequences was determined in the present study by looking at the composition of the affected fish production, and the status of different fish products on the markets. We propose a methodology to characterize market position for this set of nine species. The selected species represent a significant...

Anatomy and physiology of digestive tract of crustaceans decapods reared in aquaculture
Provedor de dados: 5
Autores: Ceccaldi, H.
The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics....

Anatomy of a compound delta from the post-glacial transgressive record in the Adriatic Sea
Provedor de dados: 5
Autores: Pellegrini, Claudio; Maselli, Vittorio; Cattaneo, Antonio; Piva, Andrea; Ceregato, Alessandro; Trincardi, Fabio.
On the Mediterranean continental shelves the post-glacial transgressive succession is a complex picture composed by seaward progradations, related to sea level stillstands and/or increased sediment supply to the coasts, and minor flooding surfaces, associated to phases of enhanced rates of sea level rise. Among Late Pleistocene examples, major mid-shelf progradations have been related to the short-term climatic reversal of the Younger Dryas event, a period during which the combination of increased sediment supply from rivers and reduced rates of sea level rise promoted the formation of progradations up to tens-meter thick. While the documentation of coastal and subaqueous progradations recording the Younger Dryas interval are widely reported in the...

Anatomy of Labrador Sea Heinrich layers
Provedor de dados: 5
Autores: Hesse, Reinhard; Khodabakhsh, Saeed.
Heinrich layers (H-layers) are distinct, decimetre to centimetre thick layers of ice-rafted debris (IRD) that were deposited in the North Atlantic during the Late and middle Pleistocene. H-layers (H-layers) are characterized by high detrital carbonate and low foraminifera contents. In the Labrador Sea, H-layers reach metre thickness in some proximal core sites near the iceberg source of the Hudson Strait ice stream and show five distinct depositional facies involving sediment lofting and low-density turbidity currents as sediment delivery processes besides ice rafting. Thick massive ice-rafted layers (type I H-layers) occur in the most proximal parts of H-layer 3 and older H-layers. Within 300 km distance from the assumed Hudson Strait ice stream terminus,...

Ancestral gene acquisition as the key to virulence potential in environmental Vibrio populations
Provedor de dados: 5
Autores: Bruto, Maxime; Labreuche, Yannick; James, Adele; Piel, Damien; Chenivesse, Sabine; Petton, Bruno; Polz, Martin F.; Le Roux, Frederique.
Diseases of marine animals caused by bacteria of the genus Vibrio are on the rise worldwide. Understanding the eco-evolutionary dynamics of these infectious agents is important for predicting and managing these diseases. Yet, compared to Vibrio infecting humans, knowledge of their role as animal pathogens is scarce. Here we ask how widespread is virulence among ecologically differentiated Vibrio populations, and what is the nature and frequency of virulence genes within these populations? We use a combination of population genomics and molecular genetics to assay hundreds of Vibrio strains for their virulence in the oyster Crassostrea gigas, a unique animal model that allows high-throughput infection assays. We show that within the diverse Splendidus...

Anchovy (Engraulis encrasicolus) egg density measurements in the Bay of Biscay: evidence for the spatial variation in egg density with sea surface salinity
Provedor de dados: 5
Autores: Goarant, Anne; Petitgas, Pierre; Bourriau, Paul.
Knowledge of the pelagic vertical distribution of fish eggs is central for several aspects of fisheries science including fisheries recruitment and egg production studies. In modelling egg vertical distributions, variation in fish egg density is an important issue. Though variation in egg density between individual eggs has been reported, evidence for significant spatial variation in egg density is novel. The present study provides evidence that egg density of anchovy (Engraulis encrasicolus) varies spatially across spawning sites in the Bay of Biscay, depending on the regional scale variation in sea water properties due to river discharge. We measured the density of the eggs using a density gradient column at 17 stations in 2005 and 2006 as well as their...

The abundance and spatial occupation of European anchovy Engraulis encrasicolus have increased in the North Sea since the mid-1990s. We use a cross-disciplinary approach combining genetics, transport modelling, survey time series analyses and physical oceanographic modelling to investigate 3 hypotheses on the reasons for this change. Evidence from connectivity studies suggests that the population of North Sea anchovy is separate from that in the Bay of Biscay. The recruitment pulses observed in survey data fit a life cycle which includes spawning in early summer and larval development in late summer. This also supports the concept of population expansion originating from local remnant population(s). In terms of growth physiology, suitable thermal windows...

ANDRO: An Argo-Based Deep Displacement Dataset
Provedor de dados: 5
Autores: Ollitrault, Michel; Rannou, Jean Philippe.
During the first decade of the twenty-first century, more than 6000 Argo floats have been launched over the World Ocean, gathering temperature and salinity data from the upper 2000 m, at a 10-day or so sampling period. Meanwhile their deep displacements can be used to map the ocean circulation at their drifting depth (mostly around 1000 m). A comprehensive processing of the whole Argo dataset collected prior to 1 January 2010 has been performed to produce a world-wide dataset of deep displacements. This numerical atlas, named ANDRO, after a traditional dance of Brittany meaning a swirl, comprises some 600 000 deep displacements. These displacements, based on Argo or GPS surface locations only, have been fully checked and corrected for possible errors found...

Anesthesia in Pacific oyster, Crassostrea gigas
Provedor de dados: 5
Autores: Suquet, Marc; De Kermoysan, Goulwen; Araya, Ricardo Gonzalez; Queau, Isabelle; Lebrun, Luc; Le Souchu, Pierrick; Mingant, Christian.
A reliable anaesthesia and sampling protocol for Pacific oysters will enable experiments to be conducted without sacrificing animals and will facilitate successive sampling of individuals for gametogenesis studies. As no such techniques were available for Crassostrea gigas, the present study aimed to define suitable anaesthetic conditions for use with this species. Three groups of ten oysters (mean weight +/- SD, 32.1 +/- 9.0 g) were anaesthetised in 5 L containers. Among different chemicals: benzocaine, eugenol and three different types of magnesium chloride (a laboratory one Flucka (R) - and two designed for agriculture - DEUSA International (R) and Dead SeaWorks (R)) and concentrations tested, one laboratory (concentration: 72 g L-1) and one...

Autores: Boudry, Pierre; Leitao, Alexandra; Mccombie, Helen; Thiriot-quievreux, Catherine.
Cytogenetic abnormalities arising both in mitosis and meiosis are known to be common in bivalves. Here we review result obtained from the observations of somatic aneuploidy in different populations of the commercially important Pacific oyster, Crassostrea gigas. The oysters studied were either (1) produced in IFREMER hatcheries between 1986 and 1999, (some of these were part of the EU funded programme GENEPHYS); or (2) collected from wild populations along the French Atlantic coast. Chromosome numbers were scored from 30 mitotic metaphases in gill tissue per  individual studied. Aneuploid cells (2n - X) were observed in all the 13 populations studied. A highly significant negative correlation was observed between the level of aneuploidy and growth, i.e....

Angular dependence of K-distributed sonar data
Provedor de dados: 5
Autores: Le Chenadec, Gilles; Boucher, Jean-marc; Lurton, Xavier.
Backscattered signal statistics are widely used for target detection and seafloor characterization. The K-distribution shows interesting properties for describing experimental backscattered intensity statistics. In addition to the fact that its probability distribution function accurately fits actual sonar data, it advantageously provides a physical interpretation linked to the backscattering phenomenon. Sonar systems usually record backscattered signals from a wide angular range across the ship's track. In this context, previous studies have shown that backscatter statistics strongly depend on the incidence angle. In this paper, we propose an extension of previous works to model the angular evolution of the K-distribution shape parameter. This evolution...

Wild and farmed animals are key elements of natural and managed ecosystems that deliver functions such as pollination, pest control and nutrient cycling within the broader roles they play in contributing to biodiversity and to every category of ecosystem services. They are subjected to global changes with a profound impact on the natural range and viability of animal species, the emergence and spatial distribution of pathogens, land use, ecosystem services and farming sustainability. We urgently need to improve our understanding of how animal populations can respond adaptively and therefore sustainably to these new selective pressures. In this context, we explored the common points between animal production science and animal ecology to identify promising...

Autores: Mcmahon, Cr; Autret, Emmanuelle; Houghton, Jdr; Lovell, P; Myers, Ae; Hays, Gc.
Climate change is perhaps the most pressing and urgent environmental issue facing the world today. However our ability to predict and quantify the consequences of this change is severely limited by the paucity of in situ oceanographic measurements. Marine animals equipped with sophisticated oceanographic data loggers to study their behavior offer one solution to this problem because marine animals range widely across the world's ocean basins and visit remote and often inaccessible locations. However, unlike the information being collected from conventional oceanographic sensing equipment, which has been validated, the data collected from instruments deployed on marine animals over long periods has not. This is the first long-term study to validate in situ...

Provedor de dados: 5
Autores: Mazzullo, Alessandro; Stutzmann, Eleonore; Montagner, Jean-paul; Kiselev, Sergey; Maurya, Satish; Barruol, Guilhem; Sigloch, Karin.
In the western Indian Ocean, the Reunion hot spot is one of the most active volcanoes on Earth. Temporal interactions between ridges and plumes have shaped the structure of the zone. This study investigates the mantle structure using data from the Reunion Hotspot and Upper Mantle-Reunions Unterer Mantel (RHUM-RUM) project, which significantly increased the seismic coverage of the western part of the Indian Ocean. For more than 1year, 57 ocean bottom seismometer stations and 23 temporary land stations were deployed over this area. For each earthquake station path, the Rayleigh wave fundamental mode phase velocities were measured for the periods from 30s to 300s and group velocities for the period from 16s to 250s. A three-dimensional model of the shear...

Annelid assemblages in soft bottoms subjected to human impact in the Urias estuary (Sinaloa, Mexico)
Provedor de dados: 5
Autores: Mendez, N.
The annelid fauna inhabiting soft bottoms was analysed during February and April, 1997 in the Urfas estuary which is mostly surrounded by mangrove swamps, but is also subjected to the effect of several anthropogenic activities, Classification and ordination techniques were used to perform the characterisation of the system based on the annelid assemblages according to environmental variables (mainly organic matter content and percentage of mud). Three zones were found: (1) 'very polluted zone', in front of a slaughterhouse and a fish processing factory with a total lack of macrofauna due to the strong enrichment of the sediment in organic matters (2) 'polluted zones', characterised by the sporadic presence of oligochaetes in front of a domestic sewage...

Annual and seasonal dynamics of deep-sea megafaunal epibenthic communities in Barkley Canyon (British Columbia, Canada): a response to climatology, surface productivity and benthic boundary layer variation
Provedor de dados: 5
Autores: Chauvet, Pauline; Metaxas, Anna; Hay, Alex E.; Matabos, Marjolaine.
Understanding the impact of the environment on temporal trends in the composition and abundance of deep-sea species is essential for forecasting evolution of the community in the context of climate change. The recent development of deep-sea observatories enables multidisciplinary studies of long duration and high temporal resolution. We used a platform at the Ocean Networks Canada NEPTUNE Observatory located in the axis of Barkley Canyon between June 2012 and January 2015 to: (1) characterize the megabenthic community and the environmental conditions in the canyon; (2) investigate temporal patterns in the faunal community; and (3) determine the influence of environmental conditions on the observed patterns. The megafaunal epibenthic community, which...

Annual and spatial variation in the Abra community in Liverpool Bay
Provedor de dados: 5
Autores: Rees, Eis; Walker, Ajm.
Based on 12 years of sampling in Liverpool Bay a number of spatial and temporal variants of the Abra community can be recognised: a) species poor localities that are consistently dominated by Pectinaria koreni or Abra alba ; b) unstable fluid muds with ephemeral recruitments of Pectinaria ; c) species rich localities with a range of alternative dominants; d) heterogeneous offshore localities that are temporarily colonised by Abra community species. General colonisation events occurred in 1972 and 1978 which may be synchronised with events elsewhere in the North Sea.

Annual cycles of chlorophyll-a, non-algal suspended particulate matter, and turbidity observed from space and in-situ in coastal waters
Provedor de dados: 5
Autores: Gohin, Francis.
Sea surface temperature, chlorophyll, and turbidity are three variables of the coastal environment commonly measured by monitoring networks. The observation networks are often based on coastal stations, which do not provide a sufficient coverage to validate the model outputs or to be used in assimilation over the continental shelf. Conversely, the products derived from satellite reflectance generally show a decreasing quality shoreward, and an assessment of the limitation of these data is required. The annual cycle, mean, and percentile 90 of the chlorophyll concentration derived from MERIS/ESA and MODIS/NASA data processed with a dedicated algorithm have been compared to in-situ observations at twenty-six selected stations from the Mediterranean Sea to...

Annual geochemical mass balances in waters of the Firth of Clyde
Provedor de dados: 5
Autores: Muller, Fll; Balls, Pw; Tranter, M.
A first-order mass balance of twelve minor and trace elements in the coastal sea area of the Firth of Clyde is presented for the period August 1989-July 1990. It is based on our own four sets of chemical data collected in the Clyde Estuary and Firth of Clyde over that period, complemented by independent information relating to water column hydrography, rainfall, wind speed, river discharge, as well as sewage sludge and dredged material disposed of at sea. Terrigenous inputs were measured or estimated as continuous functions of time. Mean exchange rates with the open shelf were calculated over four periods representative of 77 % of the one-year period considered here. All these fluxes were subsequently converted to monthly values to facilitate...

Annual nitrate drawdown observed by SOCCOM profiling floats and the relationship to annual net community production
Provedor de dados: 5
Autores: Johnson, Kenneth S.; Plant, Joshua N.; Dunne, John P.; Talley, Lynne D.; Sarmiento, Jorge L.
Annual nitrate cycles have been measured throughout the pelagic waters of the Southern Ocean, including regions with seasonal ice cover and southern hemisphere subtropical zones. Vertically resolved nitrate measurements were made using in situ ultraviolet spectrophotometer (ISUS) and submersible ultraviolet nitrate analyzer (SUNA) optical nitrate sensors deployed on profiling floats. Thirty-one floats returned 40 complete annual cycles. The mean nitrate profile from the month with the highest winter nitrate minus the mean profile from the month with the lowest nitrate yields the annual nitrate drawdown. This quantity was integrated to 200 m depth and converted to carbon using the Redfield ratio to estimate annual net community production (ANCP) throughout...

Autores: Morelle, Jerome; Schapira, Mathilde; Orvain, Francis; Riou, Philippe; Lopez, Pascal Jean; Pierre-duplessix, Olivier; Rabiller, Emilie; Maheux, Frank; Simon, Benjamin; Claquin, Pascal.
Phytoplankton primary production varies considerably with environmental parameters especially in dynamic ecosystems like estuaries. The aim of this study was to investigate short-term primary production along the salinity gradient of a temperate estuary over the course of 1 year. The combination of carbon incorporation and fluorescence methods enabled primary production estimation at short spatial and temporal scales. The electron requirement for carbon fixation was investigated in relation with physical-chemical parameters to accurately estimate primary production at high frequency. These results combined with the variability of the photic layer allowed the annual estimation of primary production along the estuary. Phytoplankton dynamics was closely...

Annual variation in neustonic micro- and meso-plastic particles and zooplankton in the Bay of Calvi (Mediterranean–Corsica)
Provedor de dados: 5
Autores: Collignon, Amandine; Hecq, Jean-henri; Galgani, Francois; Collard, France; Goffart, Anne.
The annual variation in neustonic plastic particles and zooplankton was studied in the Bay of Calvi (Corsica) between 30 August 2011 and 7 August 2012. Plastic particles were classified into three size classes, small microplastics (0.2–2 mm), large microplastics (2–5 mm) and mesoplastics (5–10 mm).  74% of the 38 samples contained plastic particles of varying composition: e.g. filaments, polystyrene, thin plastic films. An average concentration of 6.2 particles/100 m2 was observed. The highest abundance values (69 particles/100 m2) observed occurred during periods of low offshore wind conditions. These values rose in the same order of magnitude as in previous studies in the North Western Mediterranean.  The relationships between the abundance values of the...

During a survey at six stations in the Dover Strait, from July 1990 to November 1991, water samples were collected to measure : suspended sediment load and its organic content; particle characteristics; photosynthesis pigments; and heavy metals. In this contribution, particle measurements are interpreted in terms of hydrodynamical effects and seasonal evolution. Multi-modal grain size spectra are indicative of depth and cross-sectional variations, from die coastline to the central waters. Tidal variations, biological productivity and wind effects can be identified. Suspended particulate matter (SPM) components (determined using SEM, when combined with size spectra) illustrate hydrodynamical, geomorphological and biological effects on the composition of the...

La recrudescence du ver Polydora dans les coquilles d'huîtres creuses observée dès l'été 1988 a pour principale conséquence le développement parfois très important de formations variqueuses et des chambres à vase à l'intérieur des huîtres, ce qui est très préjudiciable à leur qualité commerciale. Le bilan de l'infestation des coquilles d'huîtres par le ver Polydora sur le littoral normand et atlantique en mai et juin 1989 montre que les secteurs ostréicoles les plus touchés se situent à proximité de la Loire et de la Vilaine.

The appearance and changes of the oyster shell's gelatinous bags have been monitored since 1979. The increase in thickness that causes the growth into a "ball" can be explained by an overproduction of gel. The various environmental factors that can intervene in the secretion of gel are successively examined.

Four sets of measurements performed between 2005 and 2010 in the deep central Atlantic, the deep north-western Mediterranean Sea, and in the Arctic Ocean revealed strange anomalies in the performance of the Aanderaa optode 3830 sensors mounted on RCMI I current meters in low current regimes (current speeds &gt; 10 cm s(-1)). All oxygen datasets collected during these deployments showed significant drops of oxygen (50-100 mu mol) affecting the data stability of the optode sensors in low hydrodynamic conditions. High correlations between all acquired parameters (temperature, turbidity, speed and direction of currents) verified that no unusual event occurred in the mooring areas during the periods of acquisition, although natural events responsible for such...

Anomalously deep BSR related to a transient state of the gas hydrate system in the western Black Sea
Provedor de dados: 5
Autores: Ker, Stephan; Thomas, Yannick; Riboulot, Vincent; Sultan, Nabil; Bernard, Céline; Scalabrin, Carla; Ion, G; Marsset, Bruno.
A comprehensive characterization of the gas hydrate system offshore the western Black Sea was performed through an integrated analysis of geophysical data. We detected the Bottom Simulating Reflector (BSR), which marks, in this area, the base of gas hydrate stability. The observed BSR depth does not fit the theoretical steady-state base of gas hydrate stability zone (BGHSZ). We show that the disparity between the BSR and predicted BGHSZ is the result of a transient state of the hydrate system due to the ongoing re-equilibrium since the Last Glacial Maximum. When gas hydrates are brought outside the stability zone due to changes in temperature and sea level, their dissociation generates an increase in interstitial pore pressure. This process is favorable to...

Anoplodelphys G. NOV., copépode notodelphyidae parasite de didemnidae (ascidides aplousobranches) en Méditerranée
Provedor de dados: 5
Autores: Lafargue, Françoise; Laubier, Lucien.
Based upon a large collection from the western Mediterranean, a description of a new genus of notodelphyid parasitic copepod from didemnid ascidians is given. The new genus Anoplodelphys is erected for three new species found in different host species. Anoplodelphys clearly belongs to the ophioseidimorph group of notodelphyids ; within this group, the genus is mainly distinguished by the complete lack of true buccal appendages, feature in common with only four previously described species. The discovery of this new genus increases the polyphyletic trend within the ophioseidimorph notodelphyids. The host specificity is extremely narrow : all three new species of Anoplodelphys live in several species of the large genus Didemnum. Some remarks on the host...

Autores: Matthews, Alan; Azrieli-tal, Irit; Benkovitz, Ayelet; Bar-matthews, Miryam; Vance, Derek; Poulton, Simon W.; Teutsch, Nadya; Almogi-labin, Ahuva; Archer, Corey.
Redox conditions and the mechanisms of redox development are a critical aspect of Eastern Mediterranean sapropels, whose formation in oxygen-depleted waters is closely related to water column stratification at times of global sea level rise and insolation maxima. Sapropels in the Nile Fan formed at relatively shallow water depths under the influence of the monsoon-driven freshwater output from the River Nile. This work evaluates the redox evolution of Holocene sapropel S1 in VALPAMED cruise core MD9509, recovered at 880 mbsl in the NE Nile Fan, using a combination of geochemical element proxies, Fe speciation, Fe and Mo isotopes studies. The productivity and redox proxies (Ba/Al, Mo/Al, U/Al, V/Al, Sb/Al) show well-defined enrichments in the sapropel, but...

This study aimed to assess the ecotoxicological effects of the interaction of fullerene (C60) and benzo[a]pyrene (B[a]P) on the marine mussel, Mytilus galloprovincialis. The uptake of nC60, B[a]P and mixtures of nC60 and B[a]P into tissues was confirmed by GC-MS, LC-HRMS and ICP-MS. Biomarkers of DNA damage as well as proteomics analysis were applied to unravel the toxic effect of B[a]P and C60. Antagonistic responses were observed at the genotoxic and proteomic level. Differentially expressed proteins (DEPs) were only identified in the B[a]P single exposure and the B[a]P mixture exposure groups containing 1 mg/L of C60, the majority of which were down-regulated (~52%). No DEPs were identified at any of the concentrations of nC60 (p &lt; 0.05, 1% FDR)....

Autores: Vangriesheim, Annick.
During the October-November 1977 R/V "Jean Charcot" cruise, bathymetric and hydrological surveys of the Eastern Vema Fracture Zone were carried out in order to moor current meters on the silliocated in the area, with the aim of evaluating the bottom water flow through this passage in the Mid-Atlantic Ridge. The sill zone in fact comprises a succession of three secondary sills situated between 40052'W and 41°02'W at about 10048'N, at depths ranging from 4600 to 4700 m. Westward of the sills, there is a thick (750-950 m) bottom water layer of Antarctic origin. The potential temperature found at the bottom is 1. 30°C. In the sill zone, the homogeneous layer is thinner and has a potential temperature of 1.40°C. Eastward of the sills, the homogeneous layer is...

The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (similar to the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential Southern Hemisphere companion to the Arctic Climate Impact Assessment.

Antarctic climate signature in the Greenland ice core record
Provedor de dados: 5
Autores: Barker, Stephen; Knorr, Gregor.
A numerical algorithm is applied to the Greenland Ice Sheet Project 2 (GISP2) dust record from Greenland to remove the abrupt changes in dust flux associated with the Dansgaard-Oeschger (D-O) oscillations of the last glacial period. The procedure is based on the assumption that the rapid changes in dust are associated with large-scale changes in atmospheric transport and implies that D-O oscillations (in terms of their atmospheric imprint) are more symmetric in form than can be inferred from Greenland temperature records. After removal of the abrupt shifts the residual, dejumped dust record is found to match Antarctic climate variability with a temporal lag of several hundred years. It is argued that such variability may reflect changes in the source...

Antarctic contribution to meltwater pulse 1A from reduced Southern Ocean overturning
Provedor de dados: 5
Autores: Golledge, N. R.; Menviel, L.; Carter, L.; Fogwill, C. J.; England, M. H.; Cortese, G.; Levy, R. H.
During the last glacial termination, the upwelling strength of the southern polar limb of the Atlantic Meridional Overturning Circulation varied, changing the ventilation and stratification of the high-latitude Southern Ocean. During the same period, at least two phases of abrupt global sea-level rise-meltwater pulses-took place. Although the timing and magnitude of these events have become better constrained, a causal link between ocean stratification, the meltwater pulses and accelerated ice loss from Antarctica has not been proven. Here we simulate Antarctic ice sheet evolution over the last 25 kyr using a data-constrained ice-sheet model forced by changes in Southern Ocean temperature from an Earth system model. Results reveal several episodes of...

Antarctic deglacial pattern in a 30 kyr record of sea surface temperature offshore South Australia
Provedor de dados: 5
Autores: Calvo, Eva; Pelejero, Carles; De Deckker, Patrick; Logan, Graham A.
Comparison of ice cores from Greenland and Antarctica shows an asynchronous two-step warming at these high latitudes during the Last Termination. However, the question whether this asynchrony extends to lower latitudes is unclear mainly due to the scarcity of paleorecords from the Southern Hemisphere. New data from a marine core collected off South Australia (similar to 36 degrees S) allows a detailed reconstruction of sea-surface temperatures over the Last Termination. This confirms the existence of an Antarctic-type deglacial pattern and shows no indication of cooling associated with the Northern Hemisphere YD event. The SST record also provides a new comparison with the more extensive paleoclimatic data available from continental Australia. This shows a...

Antarctic icebergs: A significant natural ocean sound source in the Southern Hemisphere

Autores: Matsumoto, Haru; Bohnenstiehl, Delwayne R.; Tournadre, Jean; Dziak, Robert P.; Haxel, Joseph H.; Lau, T. -k. A.; Fowler, Matt; Salo, Sigrid A.
In late 2007, two massive icebergs, C19a and B15a, drifted into open water and slowly disintegrated in the southernmost Pacific Ocean. Archived acoustic records show that the high-intensity underwater sounds accompanying this breakup increased ocean noise levels at mid-to-equatorial latitudes over a period of ∼1.5 years. More typically, seasonal variations in ocean noise, which are characterized by austral summer-highs and winter-lows, appear to be modulated by the annual cycle of Antarctic iceberg drift and subsequent disintegration. This seasonal pattern is observed in all three Oceans of the Southern Hemisphere. The life cycle of Antarctic icebergs affects not only marine ecosystem but also the sound environment in far-reaching areas and must be...

Antarctic icebergs distributions 1992-2014
Provedor de dados: 5
Autores: Tournadre, Jean; Bouhier, Nicolas; Girard-ardhuin, Fanny; Remy, F.
Basal melting of floating ice shelves and iceberg calving constitute the two almost equal paths of freshwater flux between the Antarctic ice cap and the Southern Ocean. The largest icebergs (&gt;100 km2) transport most of the ice volume but their basal melting is small compared to their breaking into smaller icebergs that constitute thus the major vector of freshwater. The archives of nine altimeters have been processed to create a database of small icebergs (&lt;8 km2) within open water containing the positions, sizes, and volumes spanning the 1992–2014 period. The intercalibrated monthly ice volumes from the different altimeters have been merged in a homogeneous 23 year climatology. The iceberg size distribution, covering the 0.1–10,000 km2 range,...

Antarctic icebergs distributions, 2002-2010
Provedor de dados: 5
Autores: Tournadre, Jean; Ardhuin, Fanny; Legresy, Benoit.
Interest for icebergs and their possible impact on southern ocean circulation and biology has increased during the recent years. While large tabular icebergs are routinely tracked and monitored using scatterometer data, the distribution of smaller icebergs (less than some km) is still largely unknown as they are difficult to detect operationally using conventional satellite data. In a recent study, Tournadre et al. (2008) showed that small icebergs can be detected, at least in open water, using high resolution (20 Hz) altimeter waveforms. In the present paper, we present an improvement of their method that allows, assuming a constant iceberg freeboard elevation and constant ice backscatter coefficient, to estimate the top-down iceberg surface area and...

Antarctic icebergs melt over the Southern Ocean : climatology and impact on sea ice
Provedor de dados: 5
Autores: Merino, Nacho; Le Sommer, Julien; Durand, Gael; Jourdain, Nicolas C.; Madec, Gurvan; Mathiot, Pierre; Tournadre, Jean.
Recent increase in Antarctic freshwater release to the Southern Ocean is suggested to contribute to change in water masses and sea ice. However, climate models differ in their representation of the freshwater sources. Recent improvements in altimetry-based detection of small icebergs and in estimates of the mass loss of Antarctica may help better constrain the values of Antarctic freshwater releases. We propose a model-based seasonal climatology of iceberg melt over the Southern Ocean using state-of-the-art observed glaciological estimates of the Antarctic mass loss. An improved version of a Lagrangian iceberg model is coupled with a global, eddy-permitting ocean/sea ice model and compared to small icebergs observations. Iceberg melt increases sea ice...

Autores: Howe, Jacob N. W.; Piotrowski, Alexander M.; Oppo, Delia W.; Huang, Kuo-fang; Mulitza, Stefan; Chiessi, Cristiano M.; Blusztajn, Jurek.
Antarctic Intermediate Water is an essential limb of the Atlantic meridional overturning circulation that redistributes heat and nutrients within the Atlantic Ocean. Existing reconstructions have yielded conflicting results on the history of Antarctic Intermediate Water penetration into the Atlantic across the most recent glacial termination. In this study we present leachate, foraminiferal, and detrital neodymium isotope data from three intermediate-depth cores collected from the southern Brazil margin in the South Atlantic covering the past 25kyr. These results reveal that strong chemical leaching following decarbonation does not extract past seawater neodymium composition in this location. The new foraminiferal records reveal no changes in seawater Nd...

Antarctic pack ice serves as habitat for microalgae which contribute to Southern Ocean primary production and serve as important food source for pelagic herbivores. Ice algal biomass is highly patchy and remains severely undersampled by classical methods such as spatially restricted ice coring surveys. Here we provide an unprecedented view of ice algal biomass distribution, mapped (as chlorophyll a) in a 100 m by 100 m area of a Weddell Sea pack ice floe, using under-ice irradiance measurements taken with an instrumented remotely operated vehicle. We identified significant correlations (p &lt; 0.001) between algal biomass and concomitant in situ surface measurements of snow depth, ice thickness, and estimated sea ice freeboard levels using a statistical...

We review the geomorphological, sedimentological and chronological evidence for palaeo-ice streams on the continental shelf of Antarctica and use this information to investigate basal conditions and processes, and to identify factors controlling grounding-line retreat. A comprehensive circum-Antarctic inventory of known palaeo-ice streams, their basal characteristics and minimum ages for their retreat following the Last Glacial Maximum (LGM) is also provided. Antarctic palaeo-ice streams are identified by a set of diagnostic landforms that, nonetheless, display considerable spatial variability due to the influence of substrate, flow velocity and subglacial processes. During the LGM, palaeo-ice streams extended, via bathymetric troughs, to the shelf edge of...

Antarctic Sea Ice Proxies from Marine and Ice Core Archives Suitable for Reconstructing Sea Ice over the past 2000 Years

Autores: Thomas, Elizabeh R; Allen, Claire S; Etourneau, Johan; King, Amy Cf; Severi, Mirko; Winton, V. Holly L.; Mueller, Juliane; Crosta, Xavier; Peck, Victoria L.
Dramatic changes in sea ice have been observed in both poles in recent decades. However, the observational period for sea ice is short, and the climate models tasked with predicting future change in sea ice struggle to capture the current Antarctic trends. Paleoclimate archives, from marine sedimentary records and coastal Antarctic ice cores, provide a means of understanding sea ice variability and its drivers over decadal to centennial timescales. In this study, we collate published records of Antarctic sea ice over the past 2000 years (2 ka). We evaluate the current proxies and explore the potential of combining marine and ice core records to produce multi-archive reconstructions. Despite identifying 92 sea ice reconstructions, the spatial and temporal...

Anthrophisation in introduction d'espèces exogènes: mise en place de l'analyse génétique d'une population invasive de bigorneaux perceurs Ocinebrellus inornatus (Recluz, 1851) dans le bassin de Marennes-Oléron

Ainsi, la découverte dans le bassin de Marennes-Oléron d'une nouvelle espèce de bigorneau perceur Ocinebrellus inornatus (Récluz,1851), originaire du Pacifique asiatique, laisse présager un accroissement des risques de mortalité pour les cheptels cultivés (huître, moule) et pour les ressources de la pêche littorale.

Five of the most recent observational methods to estimate anthropogenic CO2 (C-ant) are applied to a high-quality dataset from five representative sections of the Atlantic Ocean extending from the Arctic to the Antarctic. Between latitudes 60 degrees N-40 degrees S all methods give similar spatial distributions and magnitude of C-ant. However, discrepancies are found in some regions, in particular in the Southern Ocean and Nordic Seas. The differences in the Southern Ocean have a significant impact on the anthropogenic carbon inventories. The calculated total inventories of C-ant for the Atlantic referred to 1994 vary from 48 to 67 Pg (10(15) g) of carbon, with an average of 54 +/- 8 Pg C, which is higher than previous estimates.

Anthropogenic CO(2) in the Southern Ocean: Distribution and inventory at the Indian-Atlantic boundary (World Ocean Circulation Experiment line I6)
Provedor de dados: 5
Autores: Lo Monaco, C; Metzl, N; Poisson, A; Brunet, C; Schauer, B.
The Southern Ocean, where various water masses are formed ( mode, intermediate, deep, and bottom waters), has a high potential to absorb anthropogenic CO(2) ( C ant). However, most data-based and model estimates indicate low C(ant) inventories south of 50 degrees S. In order to investigate this paradox, the distribution of C(ant) is estimated between South Africa and Antarctica ( World Ocean Circulation Experiment ( WOCE) line I6) based on a back-calculation technique previously used in the North Atlantic ( Kortzinger et al., 1998) and adapted here for application in the Southern Ocean. At midlatitudes (30 degrees-50 degrees S), formation and spreading of mode and intermediate waters results in a deep penetration of C(ant) ( down to 2000 m). South of 50...

Estuaries serve as nursery grounds for many marine fish species. However increasing human activities within estuaries and surrounding areas lead to significant habitat loss for the juveniles and decrease the quality of the remaining habitats. This study is based on the data of 470 beam trawls from surveys that were conducted in 13 French estuaries for the purpose of the European Water Framework Directive. It aimed at testing the effects of anthropogenic disturbances on the nursery function of estuaries. With a multispecific approach based on ecological guilds, two fish metrics, abundance and species richness of Marine juvenile migrant fishes, were used as proxies for the estuarine nursery function. Indices of heavy metal and organic contaminations were...

We have investigated total Pb distributions in the water column from various sites in the north-east Atlantic. Sea water samples were collected during the Fluxatlante cruise in 1985. Total Pb ranged from 35 to 45 ng.l-1 (170-220 pmol l-1) in surface waters and decreased with depth in a manner consistent with previous findings. The high concentrations in surface waters probably reflect an important anthropogenic input of Pb from the atmosphere. Concentrations of total Pb are higher than in the western Atlantic. This difference seems to be closely related to the difference in atmospheric inputs of anthropogenic Pb. Three of the stations exhibit a specific Pb excess at the depth of the Mediterranean waters outflowing in the intermediate Atlantic waters; such...

A substantial amount of the atmospheric carbon taken up on land through photosynthesis and chemical weathering is transported laterally along the aquatic continuum from upland terrestrial ecosystems to the ocean. So far, global carbon budget estimates have implicitly assumed that the transformation and lateral transport of carbon along this aquatic continuum has remained unchanged since pre-industrial times. A synthesis of published work reveals the magnitude of present-day lateral carbon fluxes from land to ocean, and the extent to which human activities have altered these fluxes. We show that anthropogenic perturbation may have increased the flux of carbon to inland waters by as much as 1.0 Pg C yr(-1) since pre-industrial times, mainly owing to enhanced...

Anthropogenic pressure on the open ocean: The growth of ship traffic revealed by altimeter data analysis
Provedor de dados: 5
Autores: Tournadre, Jean.
Marine ecosystems are under increasing anthropogenic pressures from marine and terrestrial activities. Ship traffic, the major cause of change in the open ocean, and its temporal evolution are still largely unknown because of lack of data. Altimeter data provide a new powerful tool to detect and monitor the ship traffic through a method of analysis of echo waveform. The archive of seven altimeter missions has been processed to create a two decade database of ship locations. The estimated annual density maps compare well with the ones obtained from Automatic Identification System. The ship traffic analysis shows a global fourfold growth between 1992 and 2012, the largest increase being observed in the Indian Ocean and the Chinese seas reflecting the world...

Anti-Bacterial Activity of Phenolic Compounds against Streptococcus pyogenes
Provedor de dados: 5
Autores: Macé, Sabrina; Truelstrup Hansen, Lisbeth; Rupasinghe, H. P. Vasantha.
Background: Worldwide, Streptococcus pyogenes is the leading cause of bacterial pharyngitis. To reduce the use of antibiotics, antimicrobial phytochemical-containing remedies, which have long been in use in traditional medicine, may provide new approaches for management of streptococcal pharyngitis. The objective of this study was to assess the inhibitory activities of 25 natural phenolic compounds against three strains of S. pyogenes. Methods: After an initial screening, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the nine most effective phenolic compounds were determined. The effect of four compounds with the lowest MIC and MBC on streptococcal growth and biofilm formation was also studied. Results:...

Autores: Dheilly, Alexandra; Soum-soutera, Emmanuelle; Klein, Geraldine; Bazire, Alexis; Compere, Chantal; Haras, Dominique; Dufour, Aurelie.
Biofilm formation results in medical threats or economic losses and is therefore a major concern in a variety of domains. In two-species biofilms of marine bacteria grown under dynamic conditions, Pseudoalteromonas sp. strain 3J6 formed mixed biofilms with Bacillus sp. strain 4J6 but was largely predominant over Paracoccus sp. strain 4M6 and Vibrio sp. strain D01. The supernatant of Pseudoalteromonas sp. 3J6 liquid culture (SN3J6) was devoid of antibacterial activity against free-living Paracoccus sp. 4M6 and Vibrio sp. D01 cells, but it impaired their ability to grow as single-species biofilms and led to higher percentages of nonviable cells in 48-h biofilms. Antibiofilm molecules of SN3J6 were able to coat the glass surfaces used to grow biofilms and...

Autores: Le Norcy, Tiffany; Niemann, Hendrik; Proksch, Peter; Linossier, Isabelle; Vallee-rehel, Karine; Hellio, Claire; Fay, Fabienne.
Dibromohemibastadin-1 (DBHB) is an already known potent inhibitor of blue mussel phenoloxidase (which is a key enzyme involved in bioadhesion). Within this study, the potentiality of DBHB against microfouling has been investigated. The activity of DBHB was evaluated on key strains of bacteria and microalgae involved in marine biofilm formation and bioassays assessing impact on growth, adhesion and biofilm formation were used. To assess the efficiency of DBHB when included in a matrix, DBHB varnish was prepared and the anti-microfouling activity of coatings was assessed. Both in vitro and in situ immersions were carried out. Confocal Laser Scanning Microscopy (CLSM) was principally used to determine the biovolume and average thickness of biofilms developed...

Anticyclonic and cyclonic eddies of subtropical origin in the subantarctic zone south of Africa
Provedor de dados: 5
Autores: Arhan, Michel; Speich, Sabrina; Messager, Christophe; Dencausse, Guillaume; Fine, Rana; Boye, Marie.
Two eddies, one anticyclonic and the other cyclonic, intersected in the Subantarctic Zone south of South Africa during a hydrographic transect, are described using a large set of measurements including full depth hydrography, Acoustic Doppler Current Profiler velocities, biogeochemical tracers, air-sea fluxes and altimetric sea surface height. Both eddies have a subtropical origin. The anticyclone is an Agulhas ring with convected core water of similar to 12 degrees C, and swirl velocities of 1 m s(-1). It was 9.5 months old when sampled and had crossed the Agulhas Ridge. Though sampled in summer, it was releasing similar to 200 W m(-2) (sensible plus latent heat flux) to the atmosphere. It was observed adjacent to the Subantarctic Front, illustrating the...

Anticyclonic eddies connecting the western boundaries of Indian and Atlantic oceans
Provedor de dados: 5
Autores: Laxenaire, R.; Speich, S.; Blanke, Bruno; Chaigneau, A.; Pegliasco, C.; Stegner, A.
The Indo‐Atlantic interocean exchanges achieved by Agulhas Rings are tightly linked to global ocean circulation and climate. Yet, they are still poorly understood because they are difficult to identify and follow. We propose here an original assessment on Agulhas Rings, achieved by TOEddies, a new eddy identification and tracking algorithm that we applied over 24 years of satellite altimetry. Its main novelty lies in the detection of eddy splitting and merging events. These are particularly abundant and significantly impact the concept of a trajectory associated with a single eddy, which becomes less obvious than previously admitted. To overcome this complication, we have defined a network of segments that group together in relatively complex trajectories....

Heterocapsa triquetra (Ht), a non-toxic dinophyte, was selected to investigate the presence of pigments inhibiting melanoma cells growth. We developed an innovative microwave-assisted extraction process (MAE), determined the Ht pigment composition using Reverse Phase-High Performance Liquid Chromatography (HPLC) and high-resolution Ultra Performance Liquid Chromatography-Mass Spectrometry E (UPLC-MSE) analysis and assessed their antiproliferative activity in human invasive melanoma cells (A2058) grown in vitro. MAE allowed a fast and efficient extraction of Ht pigments as compared with conventional processes (soaking, sonication). Seventeen pigments and derivatives were unequivocally identified by UPLC-MSᴱ in the Ht extract, among which two were supposed...

Osteosarcoma is the most frequent malignant primary bone tumor characterized by a high potency to form lung metastases. In this study, the effect of three oversulfated low molecular weight marine bacterial exopolysaccharides (OS-EPS) with different molecular weights (4, 8 and 15 kDa) were first evaluated in vitro on human and murine osteosarcoma cell lines. Different biological activities were studied: cell proliferation, cell adhesion and migration, matrix metalloproteinase expression. This in vitro study showed that only the OS-EPS 15 kDa derivative could inhibit the invasiveness of osteosarcoma cells with an inhibition rate close to 90%. Moreover, this derivative was potent to inhibit both migration and invasiveness of osteosarcoma cell lines; had no...

The search for novel compounds of marine origin has increased in the last decades for their application in various areas such as pharmaceutical, human or animal nutrition, cosmetics or bioenergy. In this context of blue technology development, microalgae are of particular interest due to their immense biodiversity and their relatively simple growth needs. In this review, we discuss about the promising use of microalgae and microalgal compounds as sources of natural antibiotics against human pathogens but also about their potential to limit microbial infections in aquaculture. An alternative to conventional antibiotics is needed as the microbial resistance to these drugs is increasing in humans and animals. Furthermore, using natural antibiotics for...

Although antimicrobial histones have been isolated from multiple metazoan species, their role in host defense has long remained unanswered. We found here that the hemocytes of the oyster Crassostrea gigas release antimicrobial H1-like and H5-like histones in response to tissue damage and infection. These antimicrobial histones were shown to be associated with extracellular DNA networks released by hemocytes, the circulating immune cells of invertebrates, in response to immune challenge. The hemocyte-released DNA was found to surround and entangle vibrios. This defense mechanism is reminiscent of the neutrophil extracellular traps (ETs) recently described in vertebrates. Importantly, oyster ETs were evidenced in vivo in hemocyte-infiltrated interstitial...

The symbiotic shrimp Rimicaris exoculata dominates the macrofauna inhabiting the active smokers of the deep-sea mid Atlantic ridge vent fields. We investigated the nature of the host mechanisms controlling the vital and highly specialized ectosymbiotic community confined into its cephalothoracic cavity. R. exoculata belongs to the Pleocyemata, crustacean brooding eggs, usually producing Type I crustins. Unexpectedly, a novel anti-Gram-positive type II crustin was molecularly identified in R. exoculata. Re-crustin is mainly produced by the appendages and the inner surfaces of the cephalothoracic cavity, embedding target epibionts. Symbiosis acquisition and regulating mechanisms are still poorly understood. Yet, symbiotic communities were identified at...

Anti-predator response of Haliotis tuberculata is modified after only one generation of domestication

Autores: Roussel, Sabine; Bisch, T; Lachambre, S; Boudry, Pierre; Gervois, Jl; Lambert, Christophe; Huchette, S; Day, R.
Domestication of Haliotis tuberculata has only recently begun. During the process, we expect that behavioural and physiological traits may evolve to become more adapted to their captive environment. These modifications may result from intentional selection of production traits or unconscious and unintentional selection due to conditions experienced in the farm environment. To study this process at the earliest stage, the progeny of 3 different broodstocks obtained from wild parents, selected farmed abalone and randomly sampled farmed abalone, were studied. After rearing for 16 mo in separate tanks, offspring from the 3 progenies were placed together in sea cages at the same density. After 3 yr, behavioural traits were studied, and the immune status after a...

The glaucophyte Cyanophora paradoxa (Cp) was chemically investigated to identify pigments efficiently inhibiting malignant melanoma, mammary carcinoma and lung adenocarcinoma cells growth. Cp water and ethanol extracts significantly inhibited the growth of the three cancer cell lines in vitro, at 100 mu g.mL(-1). Flash chromatography of the Cp ethanol extract, devoid of c-phycocyanin and allophycocyanin, enabled the collection of eight fractions, four of which strongly inhibited cancer cells growth at 100 mu g.mL(-1). Particularly, two fractions inhibited more than 90% of the melanoma cells growth, one inducing apoptosis in the three cancer cells lines. The detailed analysis of Cp pigment composition resulted in the discrimination of 17 molecules, ten of...

Dunaliella tertiolecta (DT) was chemically investigated to isolate molecules inhibiting cancer cell proliferation and inducing apoptosis in vitro. The potency to inhibit cell growth was used for the bio-guided fractionation and isolation of active compounds using chromatographic techniques. The DT dichloromethane extract exhibited a strong anti-proliferative activity on MCF-7 and LNCaP cells, and was further fractionated and sub-fractionated by RP-HPLC. High resolution mass spectrometry and spectrophotometric analysis unequivocally identified violaxanthin as the most antiproliferative molecule present in DT DCM extract. Violaxanthin purified from DT induced MCF-7 dose- dependent growth inhibition in continuous and discontinuous treatments, at...

Antimetastatic properties on both murine and human osteosarcoma cell lines (POS-1 and KHOS) have been evidenced using exopolysaccharide (EPS) derivatives, produced by Alteromonas infernus bacterium. These derivatives had no significant effect on the cell cycle neither a pro-apoptotic effect on osteosarcoma cells. Based on this observation, these EPSs could be employed as new drug delivery systems for therapeutic uses. A theranostic approach, i.e., combination of a predictive biomarker with a therapeutic agent, has been developed notably by combining with true pair of theranostic radionuclides, such as scandium 47Sc/44Sc. However, it is crucial to ensure that, once complexation is done, the biological properties of the vector remain intact, allowing the...

Anti-rabbit immunoglobulin G detection in complex medium by PM-RAIRS and QCM Influence of the antibody immobilisation method
Provedor de dados: 5
Autores: Briand, Elisabeth; Salmain, M; Compere, Chantal; Pradier, C.
Two antibody immobilisation procedures were compared to set up an immunosensor for goat anti-rabbit immunoglobulin (anti-rIgG), i.e. rIgG covalently bound or immobilised via affinity to protein A (PrA). In both cases, the first layer of protein was covalently bound to a mixed self-assembled monolayer (SAM) of mercaptoundecanoic acid (MUA) and mercaptohexanol (C6OH) on a gold surface. The elaboration of the sensitive surfaces, as well as their selectivity and sensitivity were studied step by step by polarization modulation-reflection absorption infra-red spectroscopy (PM-RAIRS) and quartz crystal trticrobalance (QCM) with impedance measurement. QCM measurements showed that the viscoelastic properties of the antibody layer were markedly modified during the...

Water-soluble sulfated polysaccharides isolated from two red algae Sphaerococcus coronopifolius (Gigartinales, Sphaerococcaceae) and Boergeseniella thuyoides (Ceramiales, Rhodomelaceae) collected on the coast of Morocco inhibited in vitro replication of the Human Immunodeficiency Virus (HIV) at 12.5 mu g/mL. In addition, polysaccharides were capable of inhibiting the in vitro replication of Herpes simplex virus type 1 (HSV-1) on Vero cells values of EC(50) of 4.1 and 17.2 mu g/mL, respectively. The adsorption step of HSV-1 to the host cell seems to be the specific target for polysaccharide action. While for HIV-1, these results suggest a direct inhibitory effect on HIV-1 replication by controlling the appearance of the new generations of virus and...

Antiviral immunity in marine molluscs
Provedor de dados: 5
Autores: Green, Timothy J.; Raftos, David; Speck, Peter; Montagnani, Caroline.
Marine molluscs, like all living organisms, are constantly exposed to viruses and have evolved efficient antiviral defences. We review here recent developments in molluscan antiviral immunity against viruses belonging to the order Herpesvirales. Emerging results suggest an interferon-like response and autophagy are involved in the antiviral defence of bivalves to viral infection. Multifunctional plasma proteins from gastropods and bivalves have been identified to have broadspectrum antiviral activity against mammalian viruses. The antiviral defences present in molluscs can be enhanced by genetic selection, as shown by the presence of oyster strains specifically resistant to ostreid herpesvirus type 1. Whether varying amounts or different isofornns of these...

Antiviral immunity in the Pacific oyster, Crassostrea gigas: last development and perspective
Provedor de dados: 5
Autores: Renault, Tristan; Faury, Nicole; Barbosa, Valerie; Moreau, Kevin; Haffner, Philippe; Pepin, Jean-francois.
Herpes-like viruses have been reported last decades in various marine mollusc species in association with mortality outbreaks throughout the world (Renault &amp; Novoa 2004). One of these viruses isolated during French outbreaks has been characterised as an unassigned member of the Herpesviridae family and named ostreid herpes virus 1 (OsHV-1) or Pacific oyster herpes virus (Davison et al. 2005). Studying anti-viral non-specific defence mechanisms (innate immunity) is of great interest, because they constitute the only one in molluscs. Therefore, innate immunity has be investigated in the Pacific cupped oyster, Crassostrea gigas. The main aim of the work was focused on the identification and the characterisation of genes induced by OsHV-1 in the Pacific...

Apercu sur la biologie du poisson cichlide Tylochromis jentinki jentinki en lagune Ebrie (Cote d'Ivoire)
Provedor de dados: 5
Autores: Amon-kothias, J B.
In the Ebrie lagoon, the reproductive season of T. jentinki jentinki ranges from August to Februarywith a main spawning period in November, which is related to the rising of lagoon water level. The size of both males and females at first sexual maturity is about 160 mm fork-length. Each female of T. jentinki jentinki lays between 110 and 420 eggs depending on the size. It represents an average of about 1,100 eggs/kg weight. The female keeps the eggs in its mouth: this oral incubation reaches an average of 15 days at the end of which the released fry measures from 12 to 20 mm fork length. The species growth in length has been studied by examination of scales structures (circuli and annuli). This growth, compared to other cichlids is relatively slow....

Apex, actively positioned exploration system.
Provedor de dados: 5
Autores: Greger, B.
A conceptually new, modularly designed exploration system for the deep sea (600 m) has been constructed and tested. In its base unit, different soil sampling tools can be integrated. These are, for the time being, a drill core barrel with 0 48 mm iD and a length of 500 mm for rocky basements as a box corer for softer soils as well as an orange peel grab. Towed along via a coaxial cable from a research vessel, the system is TV-guided and can be actively positioned by means of 2 thrusters in order to be lowered precisely and horizontally levelled on the seafloor. The total system is operated by the help of an onboard computer and may be controlled by sensor displays and operation messages. Microprocessors control the underwater unit which is partially...

Aphotic N2 fixation along an oligotrophic to ultraoligotrophic transect in the Western Tropical South Pacific Ocean
Provedor de dados: 5

The western tropical South Pacific (WTSP) Ocean has been recognized as a global hotspot of dinitrogen (N2) fixation. Here, as in other marine environments across the oceans, N2 fixation studies have focused in the sunlit layer. However, studies have confirmed the importance of aphotic N2 fixation activity, although until now only one had been performed in the WTSP. In order to increase our knowledge of aphotic N2 fixation in the WTSP, here we measure N2 fixation rates and identify diazotrophic phylotypes in the mesopelagic layer along a transect spanning from New Caledonia to French Polynesia. Because non-cyanobacterial diazotrophs presumably need external dissolved organic matter (DOM) sources for their nutrition, we also identified DOM compounds using...

APIS: An Auto‐Adaptive Parentage Inference Software that tolerates missing parents
Provedor de dados: 5
Autores: Griot, Ronan; Allal, Francois; Brard‐fudulea, S; Morvezen, R; Haffray, P; Phocas, F; Vandeputte, Marc.
In the context of parentage assignment using genomic markers, key issues are genotyping errors and an absence of parent genotypes because of sampling, traceability or genotyping problems. Most likelihood‐based parentage assignment software programs require a priori estimates of genotyping errors and the proportion of missing parents to set up meaningful assignment decision rules. We present here the R package APIS, which can assign offspring to their parents without any prior information other than the offspring and parental genotypes, and a user‐defined, acceptable error rate among assigned offspring. Assignment decision rules use the distributions of average Mendelian transmission probabilities, which enable estimates of the proportion of offspring with...

Appearance and spread of diseases among bivalve molluscs in the northern hemisphere in relation to international trade
Provedor de dados: 5
Autores: Renault, Tristan.
Bivalve mollusc culture is a well-developed marine aquaculture activity in many countries around the world, notably in the northern hemisphere. During the development of this activity, numerous countries have been confronted with infectious diseases of varying severity and duration. Research has been conducted to determine the aetiology, epidemiology and control measures for these epizootics. Major epizootics in bivalve molluscs have been caused by viruses, bacteria, fungi and protozoan parasites. Moreover, important commercial relations exist in marine mollusc culture between different geographical areas. This must be taken into account in explaining the appearance and the spread of some infectious diseases in several countries around the world. The...

Applicability of Dynamic Energy Budget (DEB) models across steep environmental gradients
Provedor de dados: 5
Autores: Monaco, Cristian; Mcquaid, Christopher D.
Robust ecological forecasting requires accurate predictions of physiological responses to environmental drivers. Energy budget models facilitate this by mechanistically linking biology to abiotic drivers, but are usually ground-truthed under relatively stable physical conditions, omitting temporal/spatial environmental variability. Dynamic Energy Budget (DEB) theory is a powerful framework capable of linking individual fitness to environmental drivers and we tested its ability to accommodate variability by examining model predictions across the rocky shore, a steep ecotone characterized by wide fluctuations in temperature and food availability. We parameterized DEB models for co-existing mid/high-shore (Mytilus galloprovincialis) and mid/low-shore (Perna...

Autores: Cavanie, Alain.
The spectral energy distribution of sea waves is supplied four times a day by the French Meteorological Office's DsAs model using the pressure distribution over the atlantic as input. The surface-motion spectrum furnished by the model may then be used to estimate the local current spectrum near the sea bed. The present study is based on four years (1970-1974) of DSAs data for the so-called Brittany point (47"30 N. 5"W). The data correlates reasonably well with observations made from ships in the region lying between 40 - 50 N and O - 10 W (Figure 1) . . . Plotted on Weibull paper in Figure 2 are the cumulative probability values of U as calculated from the DSAs data (U is the mean of the upper third of maximum current values at a depth of 100 m).

Provedor de dados: 5
Autores: Corre, Odile.
Parmi les différentes méthodes physiques d'analyse, la fluorescence X occupe une place importante en raison de la diversité de ses applications et de la possibilité qu'elle offre d'analyser des échantillons de façon non destructive. Jusqu'ici cependant, la mesure de "faibles concentrations" a été moins développée du fait de l'impossibilité de mesurer des intensités de fluorescence à partir de solutions tampon vis-à-vis de l'effet de matrice.

Autores: Lurton, Xavier.
Les phénomènes de propagation liés à l'utilisation de sonars actifs par petits fonds sont décrits de façon adéquate par un modèle géométrique de l'énergie moyenne. Cette approche, classique pour l'évaluation des pertes de propagation, est étendue ici aux aspects temporels du signal transmis, en particulier les niveaux de réverbération: le calcul ainsi défini permet une amélioration très significative par rapport aux méthodes usuelles par rayons propres, tant en charge de calcul qu'en fiabilité des résultats. Une autre extension est proposée pour l'évaluation de l'influence du relief de surface, dont l'effet est de diffuser l'énergie incidente vers des directions angulaires voisines: ce phénomène est traité sous forme d'un couplage entre les différentes...

Autores: Laurec, Alain; Blanc, François.
Continuous sampling is now widely used in oceanography and requires new tools for data processing. The theory of stochastic processes and especially spectral analysis offers powerful ones.  We are dealing in this paper with bivariate time series : temperature and salinity were continuously measured during the CINECA-CHARCOT II cruise, in the upwelling area of North-West Africa.  The record has been splitted into three parts corresponding to straight lines. Those time series have been prewhitened using the first finite difference filter, spectra and cross-spectra were smoothed using the Parzen window.  Power spectra reveals obvious peaks. Coherencies are higher in low frequencies. The basic phenomena, mixing due to the upwelling (transfer functions can be...

Suite aux  études concernant la mise en place d’un indice de composition pigmentaire dans les eaux de Manche-Atlantique (Lampert, 2018) et en Méditerranée (Goffart, 2018), il a été convenu de procéder à un échange de données pour ces deux façades afin d’évaluer le potentiel de ces deux indicateurs sur les façades pour lesquelles ils n’ont pas été conçus. Nous avons donc, appliqué l’indice de composition ICBC aux données obtenues entre 2009 et 2017 en Méditerranée (ICBCmed), défini une grille de classement pour l’EQR IC et finalement classé les masses d’eau afin d’inclure l’indice de composition dans l’indicateur phytoplancton de Méditerranée. Cet ICBCmed a été calculé pour les 15 points échantillonnés. Le résultat du classement est cohérent avec les...

Application de l'ozone au maintien de la fraîcheur et à la prolongation de la durée de conservation du poisson frais

Autores: Salmon, J.; Le Gall, Jean.
L'altération rapide du poisson a toujours été et est encore à l'heure actuelle, une des causes principales qui ont limité la consommation de cette importante denrée alimentaire. Sous notre climat, la chair du poisson se décompose rapidement en provoquant la formation de substances malodorantes qui, non seulement rebutent la clientèle possible, mais encore sont susceptibles d'occasionner chez le consommateur des troubles physiologiques plus ou moins graves. Or, l'appauvrissement incessant des fonds de pêche oblige actuellement les chalutiers qui ravitaillent en majeure partie le marché français en poisson, à augmenter de plus en plus leur rayon d'action. Le caractère périssable de cette denrée, la manière dont elle est encore conservée dans la plupart des...

Autores: Soudant, Dominique.
L'objectif de ce travail était de mettre en place un outil mathématique permettant de prévoir les concentrations en Dinophysis cf. acuminata, micro-algue toxique. Nous avons décidé d'utiliser des méthodes dynamiques de prévision bayésienne : modèles polynomiaux du premier, second et troisième ordre, modèle polynomial du premier ordre avec intervention, et modèle de régression multilinéaire. Les modèles polynomiaux du premier, second et troisième ordre se sont avérés inadaptés. Le modèle de régression multilinéaire a été testé avec les variables concentrations en phosphate (PO4) et en nitrate (NO3). Ce modèle est insatisfaisant du fait de l'inconstance des relations entre la concentration en Dinophysis cf. acuminata et les régresseurs. Le modèle polynomial...

Autores: Soudant, Dominique.
Le Dinophysis est une microalgue toxique à l’origine d’epidémies diarrhéiques. En dépit de nombreuses études, l’écologie et la biologie de ce genre phytoplanctonique restent mal connues. Afin de déterminer les conditions d’apparition de Dinophysis cf. acuminata sur le site d’Antifer (Normandie, France), des prélèvements d’eau de mer ont été effectués quasi-journellement pendant les périodes estivales des années 1987 à 1993. Les séries temporelles résultantes concernent la concentration de la microalgue et les facteurs chimiques, physiques et météorologiques. L’analyse de ces données à l’aide d’outils sta- tistiques classiques (e.g. régression) s’est avérée difficile (e.g. instabilité temporelle des résultats).

Autores: Kervern, G; Legall, A.
Nowadays, side-looking sonar is the only equipment able to carry out long-range underwater imaging. The use of optics is limited to short-range identification by means of conventional video-cameras. However, active optical systems (lidars) manufacturing, using a blue-green laser, will enable optics to hold its place in the field of long-range underwater imaging. After a short comparison between acoustics and optics in underwater detection and a description of the proper features of underwater optical propagation, we present the different conceivable imaging principles and propose a method to determine their performances. The experimentations described concern a lidar imager mock-up using one of the imaging principles proposed. The pictures obtained deal...

Application du test de développement embryonnaire de bivalves sur le site de Dunkerque

Autores: Delesmont, R; Delesmont, E.
La qualité biologique du milieu marin peut être appréciée à l'aide de tests utilisant des organismes vivants. Parmi ces tests le développement embryonnaire des bivalves présente un intérêt particulier car, durant cette période, les bivalves sont très sensibles à la qualité de l'eau et fournissent une réponse rapide sans demander d'apport de nourriture. Suite aux études déjà réalisées au centre Ifremer de Brest et à nos essais de 1992 et 1993, nous avons travaillé avec l' huître Crassostrea gigas de la fécondation à la fondation de larve "D" (La durée de cette période larvaire est de 24 heures à 24 OC).

Depuis le début des années soixante, une partie de cette activité est mise en danger par une autre activité, l'agriculture intensive. L'ancien marais salant de Moëze-Brouage abrite ces deux activités. De cette proximité est née la problématique agro-conchylicole. Il s'agira de savoir si les eaux rejetées par l'activité agricole peuvent être dommageables pour la conchyliculture. Pour le savoir, il s'agira de déterminer la qualité biologique des eaux de rejets -j agricoles en appliquant le test écotoxicologique dit « larve de bivalves ».

Autores: Bouix, Thomas.
Au cours de mon stage, j'ai été amené à réaliser des tests écotoxicologiques dans le but de vérifier l'impact possible sur le milieu naturel des biocides pour traiter les eaux de ballast, dans lequel celles-ci sont rejetées. J'ai ainsi pu approcher l'écotoxicologie de façon beaucoup plus pratique et concrète. Le travail que j'ai réalisé étant du travail de laboratoire, j'ai su mettre à profit mes connaissances acquises dans ce domaine au cours de ma formation à l'IUT. De plus, j'ai pu les approfondir et j'ai appris à les appliquer de façon autonome. Ce stage m'a permis de mieux cerner ce qu'est le travail d'un technicien et m'a beaucoup apporté sur le plan de l'organisation de celui-ci. Ce travail demande en effet beaucoup de rigueur et d'attention afin de...

Application d'un modèle d'écosystème pélagique au calcul des conséquences écologiques du fonctionnement d'une centrale électrique "Energie thermique des mers" à Tahiti
Provedor de dados: 5
Autores: Cousin, France.
A partir d'un premier modèle simple simulant le milieu tropical oligotrophe, un second modèle permet de prévoir les conséquences d'un rejet d'eau riche en sels nutritifs dans les eaux côtières environnant le site d'installation d'une centrale "E.T.M ". Le premier modèle simule l'évolution temporelle du cycle de l'azote sur une colonne d'eau représentée sous forme d'un système de boîtes tandis que le second est une représentation tridimensionelle du site ETM reprenant le même procédé.
