In the marine environment, positive law generates multiple zones and regulatory limits that overlap in space, justifying a cartographic representation as a relevant approach to promote understanding (synthetic vision), analysis (highlighting legal anomalies, inconsistencies and redundancies), dissemination and communication to different audiences (awareness-raising). The article presents a methodology leading to the mapping of marine and coastal environmental law in West Africa, using a geographic information base to produce static or interactive cartographic representations via a Geographic Data Infrastructure (GDI). It shows the contribution of this type of mapping to a transversal approach in a multi-activity, multi-sectoral and multi-scale context. A...

Autores: Lafon, Virginie; Marieu, Vincent; Butel, Rémi; Dehouck, Aurélie; Froidefond, Jean-marie; Trut, Gilles.
This study presents the first results of an ongoing research program that aims to derive thematic maps of the intertidal lagoon of Arcachon (SW Atlantic coast of France) from space imagery. At this stage, we present the results of the tests performed on Formosat-2 imagery. Several classification strategies have been tried with the aim to discriminate the sedimentary facies and the main species of the lagoon. The classes calculated by an optimized unsupervised clustering method, based on simulated annealing global minimization technique, were used to train a supervised classification algorithm. This approach allowed us to derive a bio-sedimentary map which overall accuracy is about 84%. Also, this method has the advantage of describing the fraction of...

Cartographie des biocénoses marines de Guadeloupe à partir de données SPOT (récifs coralliens, phanérogames marines, mangroves)
Provedor de dados: 5
Autores: Chauvaud, S; Bouchon, C; Maniere, R.
In the framework of a comprehensive study of the coastal marine ecosystems of Guadeloupe Island (French West Indies), a remote sensing survey of marine communities was conducted in the Bay of the Grand Cul-de-Sac Marin. Pictures of SPOT satellite were used. At first sight, XS data from SPOT did not seem to be well adapted to extract information from deepest underwater areas. In the present study, a method for analysis of XS data was developed, which increases tenuous spectral differences associated to very low intensity signals. This technique led to a better distinction of objects, even the deepest ones. Reference surfaces were then identified in the field and a reliable supervised classification was conducted, which reflected the high diversity of...

Coastal Mediterranean lagoons are often defined as homogeneous ecosystems that home many migratory and sedentary species. They also host strong salinity gradients, depth variation and very diverse plant communities, which create small-scale heterogeneity within lagoons. This is why each lagoon must be described as an entity by itself made up of a multitude of homogeneous features, called habitats, which support specific ecological functions for organisms (nursery, feeding, protection against predators...). Although many studies have resulted in collecting high numbers of physical, chemical and biological data in coastal Mediterranean lagoons, there is currently a lack of knowledge of the spatial distribution of these habitats. In our project, we (1)...

Programme Expérimental de Réhabilitation des Fossés à Poissons (1997-2000)
Provedor de dados: 5
Autores: Bel Hassen, Malika; Prou, Jean.
Cette étude s'inscrit dans le cadre du programme expérimental de réhabilitation des fossés à poisson initié au CREAA (1997-2000). Ce programme répond à une demande régionale pour la valorisation des fossés à poissons. Cet écosystème fait partie du patrimoine régional et marque surtout son identité culturelle, une volonté locale a été manifestée pour sa conservation et valorisation. Cependant l'aménagement de ces structures s'avère très coûteux, le grossissement de poissons, essentiellement l'anguille, a été prévu afin de justifier les frais d'aménagement. Par ailleurs, l'élevage extensif de poisson s'accompagne de la pratique d'autres activités telle que l'agriculture ou l'élevage. La cohabitation de ces différents types d' activités peut déstabiliser le...

Mapping of Posidonia oceanica beds around Elba Island (western Mediterranean) with integration of direct and indirect methods
Provedor de dados: 5
Autores: Piazzi, L; Acunto, S; Cinelli, F.
Direct and indirect methods were used for mapping Posidonia oceanica beds around Elba Island. Side scan sonar and a visual infra red scanner were used to detect the extension of beds. Also, direct observations were adopted to assess the bed density and to calibrate the indirect methods. Samples of P. oceanica were collected and phenological variables and macroalgal epiphytes were studied to assess the health of the beds. P. oceanica around Elba Island covered an area of 3 680 ha. The largest beds occupied the four main gulfs of the island, characterized by gentle slopes and sandy bottoms. There, the beds showed uniform cover while a patchy structure was common on the rocky and steep bottoms of the western and south-eastern coasts of the island. P. oceanica...

Methode de cartographie quantitative des ulves "offshore"
Provedor de dados: 5
Autores: Merceron, Michel; Lunven, Michel.
Recent studies in the bays of Douarnenez and La Forêt-Fouesnant have proved that drifting stocks of « offshore » ulva exist between -2 and -20 meters depth. These stocks are nearly as important in weight as those located in the tidal zone, the only ones which are generally studied. It is likely that such « offshore » stocks also exist elsewhere in Brittany. The sampling method by discrete stations visited by divers, which has been used till now, is considered heavy and not precise enough. The new method involves a film camera set on a fish towed at a speed of a few knots. The fish is kept above the sea bottom at a chosen altitude controlled by a guiderope. The system is sturdy, autonomous, and can be easily transferred from one boat to another. The...

Autores: Pautot, Guy; Hoffert, Michel.
The cruises named COPANO have been undertaken during the summer 1979 on the R. V. Le Suroit of the CNEXO, as a part of an international research program I.C.I.M.E. The objective of this project was to study relatively small zones (a few km2) and to establish a relationship between characteristics of the manganese nodules and their environment. During the COPANO cruises, five zones have been studied: two in the northern Pacific, two in the southern Pacific and finally one in the equatorial Pacific. All the zones are centered on the longitude 134° Wand therefore their symmetry to the highly productive equatorial zone may be tested. As one of the results of the cruises is the relation between nodules and the bottom soil, established by sediment-sampling and a...

Autores: Talidec, Catherine; Berthou, Patrick; Rivoalen, Jean-jacques; Bermell, Sylvain; Guillaumont, Brigitte.
The study undertaken during the 1994-1998 planning contract on the Breton fishing fleet made it possible to underscore the size of the economic activity in regional territorial waters: More than 85% of the ships work there. This space, which is a matter of national sovereignty, is mainly managed at the regional level. To clarify the paths that may need to be taken, it seemed opportune to us to identify spatially the coastal fisheries, as well as the main current problems of planning.  The fishing zones were mapped. This work required special surveys of the local fishing committees, because it could not be done from existing fishing statistics. The surveys allowed us to approach the localization of the various trades' fishing zones on maps at 1/50,000, as...

Whatever their geographical or political point of view, Sea and coastal strategies highlight an “abyssal need” for knowledge and frequently call for a reinforcement and a better valorization of research in Marine Sciences and Technologies (MST). But, when a French public research resources inventory is needed, in the perspective of constructing a consistent action plan, we lack a framework to define thematic and disciplinary perimeter to be taken into account, to identify available data, to choose practical evaluation or estimation methods. The following study is a proposal to answer these questions. The methodology is mainly based on data collected by French High Council for Evaluation of Research and Higher Education (Hcéres) and completed by an inquiry....

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.

Développement de marqueurs moléculaires liés à la résistance à la mortalité estivale chez l'huître creuse Crassostrea gigas - Approche QTL
Provedor de dados: 5
Autores: Sauvage, Christopher.
The Pacific oyster Crassostrea gigas is the most cultivated marine species in the world (4.2 million tonnes for a turnover of 3.5 billion US dollars according to the FAO 2005). Flat oyster culture is one of the components of the French economic activity. However, for more than 15 years, farms have had to face some summer mortality episodes (30 %-60 %), that could jeopardize European mollusc culture competitivity. More than the economical importance of C. gigas, which justifies a great research effort, oysters constitute a study model of the complex physiological and genetic basis (i.e. growth, reproduction, and survival) strongly correlated to the oyster's response to different environmental conditions. One of the considered solutions is the selection of...

Coastal zones inventory by high resolution satellites
Provedor de dados: 5
Autores: Loubersac, Lionel.
The development of tools for assessing impacts on coastal environments is a reality. These impact assessments need both baseline and monitoring studies. Satellite remote sensing data would be useful for coastal inventories (baselines) and monitoring if high spatial and temporal resolutions are yield compatible. An overview of the various sensors that could be used is presented. The constraints linked to the different resolutions are exposed. An example based on Spot simulated data and trends are developed.

Provedor de dados: 5
Autores: Populus, Jacques; Loubersac, Lionel; Prou, Jean; Kerdreux, Michel; Le Moine, Olivier.
In Marennes-Oléron, Héral (1986) described the relationship between the annual production and the oysters' biomass over a century. His conclusion is that the drop in the growth of oysters was caused by an "overstorage" considering the trophic capacity of the basin. Moreover, the large intertidal spaces, though providing a great opportunity for mollusc culture, suffer from a large bio-deposition (Sornin 1983) which tends to intensify the sedimentation of the basin. The spatial management of oyster culture could be a key factor for its long-term development. In collaboration with the French Marine Affairs, in charge of the cadastral management, the IFREMER has developed a geographical information system enabling the gathering under the same geographic...

Cartographie et évaluation du stock de crépidules en baie du Mont Saint-Michel, en 2004
Provedor de dados: 5
Autores: Blanchard, Michel; Clabaut, Philippe; Abernot-le Gac, Chantal.
In 2003 and 2004, 3 cruises were organized using observations systems and sampling techniques to carry out cartography and stock assessment of the Slipper-limpet population (Crepidula fornicata) in the bay of Mont-Saint-Michel (Western Channel). This was done as part of the National Programme of Coastal Environment (Programme National d'Environnement Côtier - PNEC). The study helped to update previous data collected in 1995-96 with similar techniques : side-scan-sonar and submarine video for observation, and scuba diving and grabs for samples collection.

Mapping marine habitats with high resolution sidescan sonar
Provedor de dados: 5
Autores: Mcrea, Je; Greene, Hg; O'Connell, Vm; Wakefield, Ww.
The application of marine geophysics and GIS techniques to the characterization of benthic habitats has increased the ability of fisheries managers to assess distribution and habitat types beyond common practices. We report upon a 150 kHz sidescan sonar survey offshore of Kruzof Island, Alaska undertaken to characterize rockfish (Sebastes) habitat. Using GIS, MapGrafix and Map*Factory we determined the percentage of seafloor cover that exists in our survey area. Bathymetry in the study area was determined with sidescan interferometry. All XYZ data were gridded using Surfer and plotted in shaded relief, bathymetric contour, and 3-dimensional formats. Contoured bathymetry was used as an overlay in MapGrafix. Small sub-areas were extracted from the...

Emergence of biodiversity research and main progress from Ifremer
Provedor de dados: 5
Autores: Desbruyeres, Daniel; Goulletquer, Philippe.
Research needs and interests on biodiversity have drastically increased since the Rio Conference (1992). The main conclusions from the Millennium Ecosystem Assessment (MEA, 2001) carried out by the UN and the demonstration of the critical role of biodiversity in maintaining ecosystems services have strengthened research interests on biodiversity. Moreover, the systemic approach generalization, complex system modeling, confluence of thematic prompting new scientific concepts, and multi-scalar – multifunctional approach have induced significant changes to the scientific context. A review of major advances on biodiversity monitoring and research resulting from Ifremer programs will be presented considering deep sea as well as coastal ecosystems and associated...

Un bilan de la télédétection appliquée aux milieux coralliens
Provedor de dados: 5
Autores: Andrefouet, Serge; Maritorena, Stéphane; Loubersac, Lionel.
The aim of this paper is to present in a practical fashion the status of the use of remote sensing for the study of coral reef environments through the analysis of work published in the years 1980-2000. We review the scales of the potential work and of that actually conducted, the principal applications and their limiting factors. We detail these limitations which are of a technological nature (spatial and spectral resolution of sensors), as well as often of a conceptual (role of remote sensing in the study) or methodological (image processing) nature. The understanding of these limitations, in relation to the reality of the field, allows identification of work which could be undertaken in the years 2000.

For the first time ever at such a spatial scale, the EPICURE project is using the complementary exosystemic, functional and fisheries approaches to analyze and compare the partially exploited fish‐populating structure of the Geyser, Zélée, and Iris banks. This project focuses on three main points, which are 1) a habitat map of the three banks and an assessment of the live coral coverage as a proxy of the Geyser bank’s health, 2) a description of fish assemblages and a functional analysis relative to habitat type and time and 3) an estimate of the abundance index in structure size of the main exploited stocks. Overall, 42 habitats over 268 km² were mapped on the Geyser bank with 534 field verifications. On the Zélée bank, 24 habitats were mapped over 183...

Structure spatiale et cartographie des peuplements benthiques du bassin de Marennes- Oléron : première approche par la méthode du krigeage
Provedor de dados: 5
Autores: Bacher, Cedric; Sauriau, Pierre-guy.
Les peuplements benthiques du bassin de Marennes-Oléron  ont été échantillonnées au printemps 1984 dans le but d'étudier le stock des compétiteurs  des populations de filtreurs cultivés (huître Crassostrea  gigas et moule Mytilus edulis). 370 échantillons ont été prélevés sur une surface d'étude de 18Okm2 en utilisant un plan aléatoire stratifié. Les résultats ont été regroupés en deux groupes d'espèces ayant des stratégies nutritionnelles différentes (mollusques déposivores ou suspensivores).  Ces deux groupes trophiques ont été cartographiés, après une transformation logarithmique en utilisant la technique du krigeage. Pour chaque groupe  trois modèles de structure spatiale ont été utilisés: covariance généralisée, semi-variogrammme unidirectionnel ou...

Apports des hautes résolutions spatiales pour l'étude et la cartographie des algues vertes.  Application à la grève de St-Michel(22)
Provedor de dados: 5
Autores: Ruiz, Olivier.
The increasing amounts of agricultural effluents associated with particular hydrodynamical locations are resulting in strong proliferations of suspended green algae Ulva lactuca. During ebb tide, the algae deposit on beaches, creating a nuisance for both tourism and fishermen. Biomass estimates are hence needed both for understanding the phenomenon and for measuring its magnitude. During the spring tide period of September 1993, two high resolutions digital sensors were run jointly on the French A.R.A.T (Remote Sensing and Atmospheric Research Aircraft). A pushbroom instrument called RAMI (run by C.N.E.S.) with spectral bands identical to those of S.P.O.T. and the Canadian C.A.S.I (which possesses a lot of spectral bands) acquired images over the sandy...

Cartographie des bancs de crépidules dans le bassin de Marennes Oléron: analyse par imagerie acoustique et sondeur de sédiment
Provedor de dados: 5
Autores: Curti, Cécile.
The slipper limpet Crepidula jornicata, gastropod introduced on the North East Atlantic coasts, is considered as an invasive species, especially in shellfish fmming areas in France. Slipper Iimpet populations have been estimated in Marennes Oléron Bay since 1980. In 1995, a sidescan sonar mapping associated to a quantitative estimation of the stocks by « grab » was carried out. This study aims to update the current mapping of slipper limpet beds in the Marennes Oléron Bay using acoustic reading techniques coupled to samples. In autumn 2008, an acoustic campaign was performed through the Ifremer boat named Haliotis and sonograms obtained during the campaign were then analysed using the software CARAIBES. Acoustic images were calibrated through30 grab...

Les cartographies annuelles des biomasses microphytobenthiques ont été réalisées pour le bassin de Marennes-Oléron. Parallèlement les cartographies des caractéristiques sédimentaires ont été établies simultanément aux cartes d'abondance et biomasse macrofauniques en portant un effort particulier sur les densités des compétiteurs des huîtres notamment les Crépidules. Simultanément les études des mécanismes contrôlant le réseau trophique sur la vasière de Brouage ont été poursuivies notamment les relations entre les flux de sels nutritifs et le microphytobenthos. L'importance de ce dernier compartiment dans la nutrition de l'huître a été clairement mis en évidence par l'utilisation des traçeurs isotopiques naturels. Enfin, les caractéristiques de filtration...

Autores: Le Moine, Olivier; Geairon, Philippe; Razet, Daniel.
Our objectives can be broken down into two main axes: -Mapping of the swamp and of its use - Thematic mapping of the trophic availability of the hydraulic units. Data acquisition has been continued throughout the year 2003 To do so, a number of technical adjustments have been necessary. In this final phase of the contract, a new point of view has been tackled: that of modelisation. Indeed, considering the complexity of the calculations used, the evaluation of the trophic availability in the different hydraulic units requires the use of such techniques and software. Spatial analyses have been continued, and a number of models aimed at simplifying measurement acquisitions have been created.
