R/V Pourquoi Pas ? Coastal and deep seas mapping and oceanographic missions, with multibeam utilization Survey of areas with a capacity of deployment of two acoustic vehicles (towed sonar as SAR), ROVs (Victor 6000) or autonomous submarine (Nautile) Sampling and analyzing of water, deposit or bedrocks with deployement of bathysonds/CTD, piston corers, dredges,... Deployement of seismic systems.

ROV Victor 6000 measurement module (2007)

Penetrometer Penfeld It’s a seabed tool that measures geotechnical parameters in the sediment thanks to an instrumented rod/cone. The penetrometer is designed to work up to 6000 m depth. The rode penetreates into the sediment over 30 meters.

Two AUVs (Aster X, Idef X) Characteristics : Weight < 1T Length 4.5m Autonomy : 100km Depth 3000m Speed : 1 – 5 knts Payloads : 200kg (air)
