IOWAGA sea-states hindcast database generated by the wave model WAVEWATCH-III and forced by ECMWF winds on the French coast of the Atlantic ocean unstructured grid over 2008-2018 period.

IOWAGA sea-states hindcast database generated by the wave model WAVEWATCH-III and forced by ECMWF winds on the North East Atlantic grid over 1990-2012 period.

The COMOR cruises, which took place on the Thalia, aim to assess the abundance of the scallop stock (and if necessary to determine the presence of toxic algae) in the Seine Bay.

This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is the Temperature. Values are expressed in Celsius Degrees. The vertical level is the sea surface.

This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is the Salinity. Values are expressed in psu. The vertical level is the seabed.

This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is Salinity. Values are expressed in psu. In each pixel the value is an average of the values of the 40 vertical levels that are considered in the model.

This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is the Kinetic Energy induced by currents caused by tide, water density gradients and action of winds. The formula used for the Kinetic Energy calculation is 0.5mv², where m is the density of seawater (1027 kg.m-3) and v is the current-induced velocity. Values are expressed in N.m-2 (Newton per square meter). The vertical level is the seabed.

Ten Random Forest models were fitted in order to characterise the environmental niche and to predict the potential spatial distribution of Zostera marina along the French western seaboard. 3 rasters are provided: 1) Habitat suitability index (values ranging from 0 to 1 when conditions are estimated to be optimal), 2) standard deviation around the mean habitat suitability index, and 3) binary suitability estimates (0= not suitable, 1=suitable). These model estimates indicate areas where the species may occur and are overall consistent with field observations but note that these maps are model-based and do not correspond to actual field observations.

The objective of this cruise, which has been taking place in the English Channel - Baie de somme since 1980, over 5 days in September, is to evaluate the natural multi-year fluctuations of the stands and to analyze the possible impact of the nuclear power plant on the marine environment and resources. It makes it possible to determine annual indices of abundance and distribution of flatfish and other species (shrimp, pout, whiting).
