Objective

Following studies conducted by RV Thalia during the PLABAS missions between 1993 and 1995 (C. Augris, Ifremer GM), we deployed the RV launch Haliotis for 6 days in the very shallow water bordering the foreshore area which aerial and terrestrial measurements can be made on. Beyond -25 m CM, the speed at which morphological characteristics change did not justify an additional survey to that of RV Thalia, except for the overlap zone required to correlate the data. The zone is under strong lithological control due to the presence of subvertical flysch layers including interbank areas, formed due to differential erosion, very locally influencing the directions of wave propagation, controlling tidal currents and trapping sedimentary particles in transit. Therefore, studying this zone should make it possible to: locally limit the wave and tidal current models by the finest possible scale of bathymetry; contribute to reconstructing the total geometry of the area by characterizing the foot of the platform in terms of morphology, type of substrate, roughness; and complement the sediment transit assessment performed on the foreshore by identifying deposition areas in furrows/interbank areas in the subtidal environment.
