Objective	Two different objectives because of the merging of two cruises: (1) ESSAUV : AUV trials, acoustic trials and fine-scale bathymetry on the future neutrinos observatory (MEUST). (2) BATHYCOR1: fine-scale bathymetry and environmental (temperature, salinity, turbidity) and hydrodynamic (near bottom currents with ADCP) parameter acquisition in a rough area where vulnerable marine ecosystems (cold-water corals) live in the head of the Cassidaigne canyon. The second objective was the fine-scale bathymetry in the Planier canyon nevertheless this objective was not accomplished because of bad weather conditions combined to technical problems. This falls under the Maritime Strategy Framework Directive MSFD project.

Summary of measurements

-12 dives by the IDEFx AUV with a multibeam echosounder (only 5 of them giving data which can be utilized).
-2 dives by the IDEFx AUV with an ADCP (with only 1 giving data which can be utilized).
-27 CTD, 24 of them in the Cassidaigne canyon.
-3 moorings for acoustic tests.
