  • Bathymetry in the North Atlantic Ocean, with a 1/8 arcminute grid spacing. This dataset consists of a bathymetric Digital Terrain Model (DTM), derived from the EM122 multibeam echosounder (12kHz) data of the R/V Marion Dufresne. The data acquisition is carried out in an opportunity mode during the ship's transit. Vertical reference: observed sea level.

  • Observing fishing landings of coastal vessels of less than 12 m in 5 regions of the French Overseas Territories since 2005 and in the Mediterranean from 2007 to 2018 makes it possible to estimate fishing efforts, catches and the landed values ​​as well as the socio-economic indicators of the fleets.

  • The national multidisciplinary RECOPESCA programme is a collaboration between volunteer fishermen and scientists for the automated collection of geolocated physical and fisheries environmental data from the coastal domain. The principle consists of installing sensors on gear to measure environmental parameters, from the surface to the bottom, and to record detailed data on fishing activity and effort. The data acquired feeds the operational coastal oceanography database (coastal component of Coriolis) and the fisheries database of the SIH (Harmonie). The programme thus responds to research issues (physical and fisheries), the implementation of the ecosystem approach to fisheries, support for public policies (DCSMM, DCF, CMEMS) and Ifremer's innovation in the coastal field.
