The Gulf of Lion is located in the north-western part of the western Mediterranean basin, between Cap Creus (Pyrenean chain) in the south-west (Spanish border) and Cap Sicié (near Toulon) in the north-east. It is characterised by a wide crescent-shaped continental shelf, 200 km long. The continental shelf reaches a maximum width of 70 km off Cap d'Agde and narrows towards the east and west as it approaches the Provencal and Pyrenean-Catalan margins. It extends between 0 and 120 to 180 m deep and has an average inclination of 0.5° (reaching up to 5° at the deltaic slopes). Numerous canyons notch the edge of the platform. The river Rhône is the main source of terrigenous inflows from the Gulf of Lion, up to about 90% (Bourrin et al., 2006), and the Rhône prodelta is an area of significant accumulation of fluvial solid inflows. The current morphology of the Gulf of Lion is strongly linked to current river flows, but also to the legacy of past environmental conditions from the last low sea level 20,000 years ago. In 2012, Ifremer had planned to produce a map of the seabed substrate in this sector based on a compilation of acoustic and sedimentary data. Indeed, the Gulf of Lion has been the subject of oceanographic studies and campaigns for many years. An inventory of the campaigns at sea had been carried out thanks to the SISMER (Scientific Information Systems for the Sea) community databases and Infoterre internet portal managed by the BRGM (the French Geological Survey). These databases had enabled the referencing of laboratories involved campaigns and samples collection in the Gulf of Lion since 1991: - Ifremer, - Shom - University of Perpignan Via Domitia (Cefrem), - Aix-Marseille University (CEREGE ; MIO Mediterranean Institute of Oceanology), - CNRS (French National Centre for Scientific Research) - Sorbonne University, - IRSN (Institute for Radiological Protection and Nuclear Safety), - the French Office for Biodiversity (OFB) (previously Marine Protected Areas Agency), - the Conseil départmental de l’Hérault ... |
