This report contains the reports of each bathymetric campaign of the DUNES project.

This report is the specification for the bathymetric survey and ADCP deployment for the project.

This report presents the results of the study of the morphodynamics of the marine dunes off Dunkirk. It was carried out from the bathymetric surveys of the DUNES project via a morphometric study of the dunes and the use of the dune tracking method.

The objectives of the DUNES project are on the one hand to understand the sedimentary and ecosystem dynamics of underwater dunes, and on the other hand to provide technology developers and industrialists in the ORE sector with complementary knowledge and approaches to work in environments with hydraulic dunes. The expected results are first of all to have a better knowledge of the physical processes and the natural functioning of hydraulic dunes, to create a free access GIS dedicated to dune fields and sandbanks, to characterize on a fine scale of the structure of food webs in dunes to understand the functioning of these particular systems, and finally to establish methodological recommendations regarding the evaluation of anthropogenic impacts on dune ecosystems.

This GIS maps the crest lines of marine dunes located on the French continental shelf from the Iroise Sea to the Belgian border.
