Geomorphological analysis of the continental slope of the Mediterranean sea, based on a 100 m Data Terrain Model (DTM). This DTM is a synthesis of data acquired during several surveys. Bibliographic references :

The national observation network for the blue mussel (MYTILOBS), set up in 2012, aims to monitor the growth and mortality of mussels produced for the market. The MYTILOBS is based on the experience of the regional network (REMOULA) which has been monitoring the growth of the blue mussel in the Charentais inlet since 2000. Monitoring mainly takes place the year following the year of capture: it thus integrates the main seasons of the biological life of the mussel, from winter maturation to spring growth, then to summer and fall fattening, the two periods when they are mainly sold. The choice of monitoring sites was decided in consultation between the Regional Environmental Resource Laboratories and the industry. For North Brittany, this is the site of Vivier-sur-Mer in (the sector of) the bay of Mont-Saint-Michel (mussel poles). Each breeding site is monitored every three months. Many parameters are measured including mussel size, weight and mortality. These data are examined taking into account environmental conditions such as temperature, salinity or the abundance and richness of the microalgae on which the shellfish feed. The Mytilobs national network is located in the main mussel-breeding regions of the Atlantic coast: Normandy, North Brittany, South Brittany, Pays de Loire and Poitou-Charentes. The sites of Agon (West Cotentin), Vivier (the bay of Mont Saint-Michel), Pont Mahe (Vilaine bay), Aiguillon (Breton inlet), Yves (Pertuis d’Antioche strait) representing, from north to south, mussel culture using poles. The Filiere site (Pertuis Breton - strait) represents mussels culture using ropes, in full water.

The definitive coastal information system, Quadrige stores coastal observation and monitoring network data. In order to manage coastal monitoring data, Ifremer developed the Quadrige² information system. Quadrige is one element of the Water Information System (SIE) http:// www.eaufrance.fr, et à ce titre, contribue aux travaux du Secrétariat d'Administration National des Données Relatives à l'Eau (SANDRE) http://www.sandre.eaufrance.fr. Quadrige Marine Zones is a reference source unique to the Quadrige system. It is used to break down the coast of the French mainland and overseas territories into large areas and to connect each one with observation and monitoring locations.

The regional bathymetric Atlantic – Channel – North-Sea DTM has a resolution of 0.001° (~111m). Its geographic coverage includes the Bay of Biscay, the English Channel and a part of the North Sea. The DTM extends from the coast to the continental slope (about of 4800m deep). This DTM is produced in the framework of the HOMONIM project which aims at improving operational forecast capabilities for the national coastal flood warning system. This DTM is offered openly on the Shom diffusion website (http://diffusion.shom.fr/produits/bathymetrie/mnt-facade-atl-homonim.html). http://dx.doi.org/10.17183/MNT_ATL100m_HOMONIM_WGS84
