On the menu for this transit: how to set up a cruise project, the planning and management of the cruise before and during the cruise, and the follow up. From logistics to science and through administration. And supported by the French Oceanographic Fleet and the Reseau des Universités Marines.

4) Sonar coverage during a dive of AUV Ulyx (gray background) covering a zone of approximately 6x3 km, with sonar swaths of about 400 m (horizontal stripes). The identified barrels shown as black dots line up along tracks followed by ships during barge dumping.

2) Barrel dumped at the seafloor at about 4700 m water depth and 3) a probable leak of unknown material - probably tar used to embed the waste in the barrels.

1) Swath of Ulyx sonar data (left) and close-up of the barrels at the seafloor, showing as bright spots (from box on the left), with the bright illuminated side by the sonar and the shadow away from the AUV.
