Bathymetric and topographic model of the island of La Réunion. Topography is from IGN data. Bathymetry is derived from the multibeam data acquired during the campaigns Forever (2006, EM12D sounder) Eroder1 (2006, EM120 sounder) and Eroder2 (2007, EM120 sounder). The grid spacing is 300m.

Bathymetric model (DTM) of the North-East Atlantic, generated from conventional multibeam bathymetry data, prior to the year 2000. The grid spacing is 1000 meters.

Geomorphological analysis of the continental slope of the Bay of Biscay based on a 100m Data Terrain Model (DTM). This DTM is a synthesis of data acquired during sea surveys ZEE 1, ZEE 2, Sedimanche, Sedifan 1, Sedifan 2, EssNaut 2009, EssReson08, ValidOp, BOBGeo 1, BOBGeo 2, EssInf.

This bathymetric model is the result of compiling data and numerical models prior to 2008 in the Bay of Biscay. These datasets are available at a resolution of 500 m and 1000 m. Contours are also available for both digital terrain model (DTM). Public access granted under certain conditions.

Under the EU Water Framework Directive (2000/60/EC), among the biological parameters involved in the assessment of coastal water bodies, the quality element "phytoplankton" is defined. This indicator Phytoplankton is made up of several indexes including a biomass index and an abundance index. Oxygen balance appearing among the elements of physicochemical quality selected for the classification of the ecological state of coastal water bodies. The quality element "benthic invertebrates" is also part of the biological parameters involved in the assessment of these water bodies.
