Seabed shear stress (in N.m-2) is a measure of the friction of water on the seabed due to waves and currents. The 90th percentile over the available period is used as layer for habitat models prediction.

Sediment average grain size in the Mediterranean was generated from sediment categories. This rough granulometry estimate may be used for habitat models at meso- and large scale.

Within the framework of the establishment of a nuclear power plant on the coast of the town of Flamanville, Electricité de France has entrusted Ifremer with ecological and fishery studies on the site's surroundings. One of the expert assessments consists of conducting two shellfish fishing campaigns each year. Their objectives are to monitor the natural fluctuations of the main indicators selected during the start-up of the plant and to evaluate the impact of the plant on the surrounding fishery.

Sediment average grain size in French Mediterranean waters was generated from sediment categories. This rough granulometry estimate may be used for habitat models at meso- and large scale.
