Objective

The BATHY-DELTA-RHONE_H cruise (August 2021) provided a high resolution bathymetry of the Rhone pro delta. It provide valuable information to evaluate the spatial sediment deposition/erosion in the mouth of the Rhone river. The new bathymetry, once processed, will be also compared to the previous observations (Maillet et al., 2006  (STRATAFORM1 (2002) and RhoneFlood (2003); Boudet, 2017, Ifremer cruises RHOSOS (2008), ROUSTAN 1 and ROUSTAN 2 (2008 et 2009), BOBORHONE (2003)). These observations will be compared with medium (2y - a new campaign is scheduled in 2023) to long term (10y) sediment transport simulations to evaluate the robustness of the model results and provide uncertainties on sediment budget estimations.

This cruise completes the BATHY-DELTA-RHONE_E cruise carried out on the N/O L'Europe towards the coast.
