Influence du positionnement des filières ostréicoles et mytilicoles dans le Pertuis Breton : Résultats préliminaires
Provedor de dados: 5
Autores: Robert, Stephane; Fillon, Alain.
La mise en place d'une nouvelle zone de filière ostréicole fait actuellement l'objet d'une demande de la Section Régionale Ré Centre-Ouest. L'objectif du projet est de transférer une partie de l'ostréiculture d'estran sur filières, le tout à biomasse constante afin d'obtenir un gain de productivité. Deux sites ont été proposés. La proximité des zones d'élevage (mytilicole et ostréicole) en filières laisse supposer une compétition possible de l'exploitation des ressources alimentaires dans l'ensemble géographique du Pertuis Breton. Par conséquent, le choix du site d'élevage est particulièrement important et doit être sélectionné de façon à minimiser l'impact sur les cultures déjà existantes. Pour cela, l'influence du positionnement des filières a été étudié...

Autores: Loubersac, Lionel; Populus, Jacques; Durand, Christophe; Prou, Jean; Kerdreux, Michel; Le Moine, Olivier.
Maintaining shellfish production activities, ensuring their quality and optimising the management of reserved space use with a perspective of sustainable growth are questions that interest a very significant block of French coastal sites. To achieve such objectives, it must especially be possible to relate the spatial distribution of the farmed stocks and environmental constraints: physical characteristics of the environment, nutritive resources, health constraints, environmental protection constraints...

Évolution récente et sédimentation des plates-formes continentales de la Corse
Provedor de dados: 5
Autores: Pluquet, Fabrice.
This work aimed at displaying and studying morphological and sedimentological features of Corsican seafloor from the coast to depths of -100m. It also aimed at a better knowledge of sediment dynamics under hydrodynamic conditions, and at a reconstitution of the late Quaternary shorelines evolution.  Careful analysis of the bathymetry has revealed a very contrasted morphology between the different areas of Corsican shelves, as it has been displayed on an synthetic geomorphological map.  In addition, an homogeneous and overall map of surficial sediments of the Corsican shelves seabed was established and two areas, the Balagne and Agriates' platforms to the North of Corsica, and the Bonifacio Straits to the South, were mapped into details. The various...

Les peuplements benthiques du plateau insulaire de la Martinique et des zones bathyales adjacentes. Cas particulier de la malacofaune
Provedor de dados: 5
Autores: Paulmier, Gerard; Durand, Francoise.
Several oceanographic surveys in Martinique waters with, as main objectives, either geological mapping and evaluating marine aggregate resources of research into deep water carcinologie resources, nafe produced interesting informtion on benthic pppulations situated from the infralittoral to the bathyal shelf, for the wole of faunistic groups and more specifically for the malacofauna. The distribution of the various faunistic group has been analysed in function to the bathymetric, edaphic and possibly, thermic factors. The infralittoral zones, up to the 20 metres isobath, and circalittoral, between 60  and 80 metres, are known to have the richest populations. Corals, sponges, polychaete annelida and molluscs are the best represented, numerically as well as...

Caractérisation des fonds marins et estimation bathymétrique par inversion de modèle de transfert radiatif : Application à l'imagerie hyperspectrale en milieu corallien
Provedor de dados: 5
Autores: Petit, Tristan.
Airborne hyperspectral imaging is a potential candidate for mapping and monitoring coral reefs at large scale and with high spatial resolution. In this thesis, we first present the processing steps to be applied to hyperspectral signals for extracting information about seabed types, bathymetry and water optical properties, and we discuss their efficiency with respect to two main confounding factors: (i) low signal to noise ratio of the measured signals, and (ii) large number and variability of physical interactions occurring between the entrance of sunlight into the atmosphere and its measurement by the hyperspectral sensor. Considering these limitations, we examine the performance of an already existing water column processing method: semi-analytical...

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...

Circulation de bord ouest de l'Atlantique Sud: analyse d'observations lagrangiennes et hydrologiques
Provedor de dados: 5
Autores: Legeais, Jean-francois.
The "World Ocean Circulation experiment" (WOCE) program in the 1990s has produced the equivalent of 300 years of subsurface floats trajectories within the Antarctic Intermediate Water (AAIW) at 800dbar in the South Atlantic ocean, and several hydrological transects. In order to compute the western boundary circulation, the flow is vertically extrapolated by referencing geostrophic hydrological profiles to float speeds. Several transects normal to the continental slope and another one parallel to it off the coast give transports of the water masses with a good transversal and longitudinal resolutions. Floats at 800dbar sampled the Intermediate Western Boundary Current (IWBC) particularly well, and enable one to analyse it from 28°S at the bifurcation of the...

In 2013, the project ‘Assessment of the renewable rate of the seawater masses in the Miquelon ‘Grand Etang’ ‘ focused essentially on (1) building a data set originating from all partners (e.g., DTAM, IGN), (2) preliminary sampling of current patterns so as to facilitate the 2014 field sampling strategy. Besides this approach, a census of aerial pictures dated from 1950, 1990 and 2005 were studied to assess the temporal trends of this geographic sector. The field work to be carried out in 2014 are: 1) Bathymetry: data acquisition in the ‘Grand Etang’ in the area presently used for mussel long lines culture to obtain a comprehensive data set, transversal profiles at the strait level at the near vicinity of the current pattern measuring station. 2) Current...

Caractérisation de la circulation autour, au-dessus et à travers (via des zones de fracture) la dorsale de Reykjanes
Provedor de dados: 5
Autores: Petit, Tillys.
The Reykjanes Ridge is a major topographic feature of the North-Atlantic Ocean that extends from Iceland to the Charlie Gibbs Fracture Zone. Located between the Iceland Basin and the Irminger Sea, the Reykjanes Ridge strongly influences the subpolar gyre circulation and is a gate toward the deep convection areas. However, the circulation and distribution across the Reykjanes Ridge has never been directly quantified such that the characterization of the connection between the Iceland Basin and the Irminger Sea is still incomplete. As part of the Reykjanes Ridge Experiment project, we were able to analyze the circulation around, above and across the Reykjanes Ridge. Mainly based on hydrographic sections along and perpendicular to the ridge axis, the aim of...

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...

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.

Evolutions bathymétrique et morphologique du bassin d'Arcachon
Provedor de dados: 5
Autores: L'Yavanc, Jacky.
La seule couverture bathymétrique complète donnant des renseignements sur l'altimétrie des estrans et sur la profondeur des chenaux date de 1864. Pour la mise en place d'un modèle hydrodynamique, une bathymétrie classique a été réalisée sur toute l'étendue du bassin d'Arcachon entre 1992 et 1993. Le premier chapitre traite : - des observations de la marée en différents points répartis autour et à l'intérieur du Bassin. Ces observations permettent notamment de mettre en évidence une déformation du plan d'eau à toutes heures de la marée. - des méthodes d'exécution et de traitement du levé bathymétrique. Le deuxième chapitre concerne l'évolution morphologique du Bassin sur une période de 130 ans. D'importantes modifications sont mises en évidence : - un...

Dynamique sédimentaire et évolution holocène d'un système macrotidal semi-fermé : l'exemple de la rade de Brest
Provedor de dados: 5
Autores: Gregoire, Gwendoline.
The bay of Brest is a tide-dominated, semi-enclosed coastal basin, which is connected with two rivers (Aulne and Elorn). Its jagged shoreline and seabed morphology constitute an ideal setting to understand sedimentary transfer at the land-sea interface. In this aim, this study is divided in two different time scale. The first (a) focuses on the present-day sedimentary bedload dynamic and the second (b) on the reconstruction of the Holocene infilling, during the last marine transgression. (a) A analyse combining a sedimentology approach and numerical has highlighted the major control of the tidal currents. Swells and rivers have a minor impact, because the inherited morphology accentuates and promotes tidal currents. There are responsible of a shelly sandy...

Cartographie des fonds de la Seudre
Provedor de dados: 5
Autores: Massard, Emilie; Geairon, Philippe.
Ce poster présente la bathymétrie du fond de Seudre. Les mesures s'effectuent par couplage d'un sondeur hydrographique à un GPS différentiel à bord d'une embarcation, permettant ainsi l'acquisition et la spatialisation de données en temps réel. Le traitement géostatique a ensuite lieu à partir d'un logiciel spécialisé pour obtenir une cartographie de la cote altimétrique du fond.

Incertitudes de mesures bathymétriques : évaluation, validation et application sur les levés bathymétriques de la Seudre et sur les bancs ostréicoles du Bassin de Marennes-Oléron
Provedor de dados: 5
Autores: Massard, Emilie.
La cartographie des fonds côtiers, utilisée jusqu'à présent pour la navigation et plus récemment en modélisation, semble aujourd'hui insuffisante pour des applications qui requièrent une donnée bathymétrique centimétrique. Grâce à une méthode d'acquisition innovante, liant un sondeur hydrographique avec un GPS différentiel, nous avons réalisé des bathymétries d' une justesse convenable, en vue de leur utilisation dans le suivi des mouvements sédimentaires. Afin de transmettre des bathymétries de qualité connue (fournie avec une exactitude précise) aux différents acteurs locaux, l'évaluation des différentes incertitudes de mesures a été réalisée : les sources d'erreur possibles provenant du sondeur hydrographique, du GPS différentiel et de la méthode d'...
