| 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.... |

| 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... |

| 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... |

| 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... |

| This report is a result of a contract between Ifremer and the French Ministry of Industry. The aim was to provide map the fisheries activity and landings for french fishing vessels, located in the Eastern Channel and the Bay of Biscay during the year 2005. Two areas have been selected: - the "Eastern Channel" area, including 7 administrative departments : Nord, Pas-de-Calais, Somme, Seine-Maritime, Eure, Calvados and Manche. - the "Loire-Gironde" area, including 4 administrative departments : Loire-Atlantique, Vendée, Charente-Maritime and Gironde. |

| 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... |

| 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. |

| 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... |

| At first, the chronology of remote sensing flights organized by CNEXO, IFP and IGN is summarized. Secondly, examples of the most commonly observed phenomena along the coastline are presented. An interpretation of the various data collected is given for the area of Roscoff, taken as a model. This interpretation is extended to draw a serie of maps of sea and coastline pollution for several days between March 18 to May 26, 1978. The maps for the 18th and 21st of March are enclosed. |

| 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)... |
