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 objective of the DiMe project was to improve the characterisation of extreme sea states with breaking waves by combining observations and modelling.

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

The objective of the ABIOP project was to develop biofouling characterisation and quantification methods to make the design and maintenance of ORE systems more reliable. ABIOP has identified the research needs that will enable better identification and management of the risks relating to the ORE components most sensitive to biofouling. Initial in situ measurements were also carried out to characterise biocolonisation in the Atlantic and Mediterranean from an engineering and environmental point of view. The necessary additional studies are being carried out within the framework of the ABIOP+ project.

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.
