Objective	Piggyback cruise during transit from Pointe-à-Pitre - La Coruna (TV_PAPCOR). Multibeam echosounder surveys were performed during this piggyback transit between Pointe-à-Pitre and Ponta Delgada. Testing to detect hydrothermal plumes on the Snake Pit and TAG vent sites and looking for hydrothermal activity in the zone of the French permit for sulphide exploration. Bathymetric survey on cluster 3 of exploration permit. Microplastics collected. Bathymetric survey at the front of the Lesser Antilles subduction margin. Checking a sounding points at 20°23'N, 053°30'W. ADCP (38kHz and 150kHz) acquisition along the entire transit (with the exception of the exploration permit zone).
