The purpose of this framework agreement is to study the intertidal sedimentary habitats 1130 and 1140, and the estuarine channel habitats, at the PNMEPMO scale and aims to: map them, determine the areas they cover, make a statement of the places of chemical contamination of the sedimentary compartment on these intertidal zones, identify potential chemical risks on sedimentary organisms and benthic communities, develop an indicator of the contamination of PNM water and complete the existing monitoring done within the framework of European WFD directives and DCSMM, Take communicating photographs for the general public.
