The aim of this action is to determine, by analyzing ROV captured video footage within trawl-free zones, the richness and composition of the benthic mesophotic communities and the type of impact of the selected métiers potentially interacting with the assemblages. Besides, this WP characterizes environmental abiotic and biotic factors. Specific activities are:

• Oceanographic surveys with ROV operations and other hydrological, bathymetric, morphobathymetric and current measures if necessary.
• To process al environmental cartography of the surveyed area in GIS format.
