| Zooplankton biomass was measured at 20 stations located along five coastal-offshore transects in the Gulf of Lions (NW Mediterranean) during spring 1998 and winter 1999, using two nets equipped with 200 and 80 Pm mesh. Biomass was twice as abundant in spring. It increased toward the coast and the west of the gulf and was positively correlated to chlorophyll, primary production and organic particulate matter and negatively to temperature and salinity. The enrichment effect of Rhone river input and the oligotrophic influence of the north Mediterranean current (NMC) were the main distribution factors of zooplankton biomass. Higher biomass was obtained in coastal stations with the 80 mum net, which sampled more efficiently young larval stages and nauplii.... |

| This article summarizes the latest knowledge on the ecology of three gobies. The authors compile data published by various scientists who carried out their research under different conditions, using a variety of methods for collecting data and processing the results. The relationship between population structure and different environmental conditions was considered for three goby species Pomatoschistus minutus (Pallas, 1770), P. microps (Kroyer, 1838) and Gobius niger Linnaeus, 1758, in different geographical areas, notably the Mediterranean (Gulf of Lions and Adriatic) and cold temperate Atlantic (north of the English Channel) parts. In the three species, the life cycles in the Mediterranean, favoured by the local hydroclimate, are "contracted" (growth is... |

| The conjugate margins system of the Gulf of Lion and West Sardinia (GLWS) represents a unique natural laboratory for addressing fundamental questions about rifting due to its landlocked situation, its youth, its thick sedimentary layers, including prominent palaeo-marker such as the MSC event, and the amount of available data and multidisciplinary studies. The main goals of the SARDINIA experiment, were to (i) investigate the deep structure of the entire system within the two conjugate margins: the Gulf of Lion and West Sardinia, (ii) characterize the nature of the crust, and (iii) define the geometry of the basin and provide important constrains on its genesis. This paper presents the results of P-wave velocity modelling on three coincident near-vertical... |

| Le présent rapport, intitulé « Le mercure en Méditerranée Nord occidentale » traite du cycle du mercure naturel et anthropique dans l’écosystème du Golfe du Lion, ses marges et la plaine abyssale adjacente. Il y aborde les niveaux de concentrations de différentes espèces chimiques du mercure, les apports de sources externes, les transformations internes et les tendances spatio-temporelles dans l’atmosphère, les eaux, les sédiments et les organismes vivants. Ce rapport a pour objectif de répondre aux attentes managériales en matière de gestion des eaux. Il fait la synthèse des connaissances et propose des actions en matière de surveillance et de recherche pour la zone considérée. |

| Small pelagic fish show a general decrease in size and body condition over the past two decades in the North-East Atlantic. The underlying factors are still not well understood, however recent studies point to a bottom-up control. In order to understand how the environment impacts the main biological functions, i.e. growth, reproduction and maintenance, we adopted a bioenergetic modelling framework based on the Dynamic Energy Budget theory. To improve the robustness of our study, we chose a comparative approach between two species, Engraulis encrasicolus and Sardina pilchardus, both living in three areas, namely the English Channel, the Bay of Biscay and the Gulf of Lion. Our model is calibrated over the Bay of Biscay and then applied to the other areas,... |

| The drastic climatic changes which characterise the cooling trend of the last few million years of Earth history led to variations in eustatic sea level that had tremendous impact on the geology and ecology of continental margins. Reconstructing a sea-level curve back in time is not an easy task. Observations of shoreline positions are always a local measurement of Relative Sea Level that needs to be corrected from the effect of tectonic and thermal subsidence, sediment loading, compaction and glacio-hydro isostasy. Extensive studies have been done for the last deglaciation and for the last 100,000 yr cycle. But very few studies deal with position of sea level during earlier cycles, simply because conditions are very rarely favourable for the preservation... |

| An analysis of sedimentological, sediment trap and hydrological data was performed to investigate the transport and fate of particulate matter in the Gulf of Lions. The sedimentological properties outline the major sedimentary units of the shelf (Rhone prodelta, mid-shelf mud belt, outer shelf) and slope. The geometry of these sedimentary units and the southwestwards increase of particulate fluxes on the slope highlight the influence of the general cyclonic circulation on the dispersion of land-derived particulate matter. Considering the known input and output terms, budgets of particulate matter and organic carbon in the Gulf of Lions are proposed. Inputs were river supply, atmospheric deposition and primary production; outputs were sediment burial and... |

| The sedimentary architecture of basins and passive margins is determined by a complex interaction of parameters, including subsidence, eustasy, and sediment supply. A quantification of the post-rift (20 Ma-0 Ma) vertical movements of the Gulf of Lion (West Mediterranean) is proposed here based on the stratigraphic study of sedimentary paleomarkers using a large 3D grid of reflection seismic data, correlations with existing drillings, and refraction data. Post-rift subsidence was measured by the direct use of sedimentary geometries analysed in 3D and validated by numerical stratigraphic modelling. Three domains of subsidence were found: on the continental shelf and slope, subsidence corresponds to a seaward tilting with different amplitudes, whereas the... |
