| On the morning of the 31th October 2000, the Italian chemical tanker “Ievoli Sun” sank in the central Channel. Her cargo presented a risk of contamination for the marine environment and nearby coastal environment. From the moment the sinking was announced, Ifremer decided to implement, in almost real time, tools to produce and communicate environmental data. This paper presents the solutions chosen to develop: - a Geographic Information System to prepare maps, - a series of simulations for dispersion at sea of dissolved products - a general information web site structure (see http://www.ifremer.fr/envlit/surveillance/ievoli.htm). This paper will go beyond technical presentations of methods, tools and results obtained to take a critical look at the site’s... |

| De manière à rechercher, lorsque c'est possible, une cohérence d'ensemble entre les stratégies des différents districts métropolitains et une optimisation des méthodes, il a été décidé la réunion de groupes d'experts au niveau national. Leur mandat concernait la définition des stratégies générales relatives aux paramètres et fréquences en vue de la mise en place du contrôle de surveillance des Eaux côtières (et des Eaux de transition lorsque les stratégies sont identiques) |

| 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... |

| In the Bay of Biscay, Cold Water Coral (CWC) habitats have been mapped in 24 out of a hundred known submarine canyons. The footprint of ROV or towed-camera transects is small compared to the size of these canyons but still, known CWC habitats totalize a linear of 46 km. The distribution of these habitats, dominated by reef-building scleractinians, antipatharians, alcyonaceans and pennatulids, is however patchy and their median size is small, ranging from 6 to 65 m. While the preservation of these Vulnerable Marine Ecosystems has become essential, all CWC habitats will not be benefit from conservation strategies due to their widespread and patchy distribution. Priorities must thus be defined. Among the criteria for such prioritization, we explore here the... |

| Les objectifs de cette étude concernent l'apport potentiel de l'imagerie satellitaire SPOT sur les marais maritimes et plus particulièrement ceux situés dans la partie centrale de la façade atlantique française, notamment au travers de l'approche multidate. Deux thèmes seront traités séparément : - Le premier thème, de loin le plus important dans ce secteur, concerne les marais endigués gérés en eau de mer. Son objectif est la détermination du taux d'occupation (zones exploitées ou abandonnées) et du type d'activité exercée. - Le second concerne quant à lui la discrimination des couverts végétaux dans les marais naturels. |

| Ce document est une traduction française que l’on espère transcrire au mieux les descriptions d’habitats de la classification EUNIS. Il vient compléter la traduction en français des habitats terrestres et d’eau douce réalisée par le MNHN‐SPN (Louvel et al., 2013). Il a pour objectif de faciliter l’appropriation de cette typologie par les acteurs concernés (scientifiques, gestionnaires ou bureaux d’études) et favoriser les échanges de connaissance sur la biodiversité des habitats benthiques en cohérence avec ce standard. Il s’agit dans ce document du dictionnaire de la typologie EUNIS dans sa version 2007, revue en 2012 pour des modifications des codes de la classification paléarctique et ceux de la classification des habitats marins de la Grande Bretagne.... |

| 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... |

| The topographical and hydrological complexity of submarine canyons, coupled with high substratum heterogeneity, make them ideal environments for cold-water coral (CWC) habitats. These habitats, including reefs, are thought to provide important functions for many organisms. The canyons incising the continental slope of the Bay of Biscay have distinct morphological differences from the north to the south. CWCs have been reported from this basin in the late 19th century; however, little is known about their present-day distribution, diversity and environmental drivers in the canyons. In this study, the characteristics and distribution of CWC habitats in the submarine canyons of the Bay of Biscay are investigated. Twenty-four canyons and three locations... |

| In the framework of the building of a nuclear plant on the site of Flamanville, the C.N.E.X.O. was asked by Electricité de France, to take care of the ecological studies. These studies divide into three main phases: - Pilot studies, which are limited and aim to draw, initially, a portrait of the site. The Flamanville report was published in April 1976. - Project studies, which were spread over two years and resulted in the writing of a reference ecological assessment. These studies were carried out on the Flamanville site from July 1976 to July 1978 and the report was published in 1979. - Monitoring studies, which focus on the more significant or sensitive parameters of the site. This report presents the result of the first monitoring year (1983) and deals... |

| The aim of this study is to model the seaweed species distribution with respect to environmental parameters. We focused on fixed species of algae, such as fucoids. Firstly, we identified environmental parameters, such as substratum nature, immersion time, exposure, etc., which determine the seaweed distribution. Secondly, we used field sampling to compute the distribution laws for seaweed according to the environmental parameters selected. Thirdly, we used the distribution laws and the environmental parameters to perform predictive mapping of seaweed belts with a fuzzy logic method. Seaweed presence is directly dependent on the nature of the substratum. In the intertidal domain we used an alternative, because seaweed beds can be observed directly. We... |
