Beginning of work for Jet Propulsion Laboratory (Nasa): in unknown area in Melville Bay (0-1000m depth), North-West of Greenland, the aim is to detect major holes in the seabed, offshore main glaciers, and to do soundings and ocean measurements (CTD), by getting close to the glaciers to see the water vertical structure evolution on continental shelf. Leader: Eric Rignot, Senior Research Scientist at JPL, Pasadena (Nasa), and Professor of Earth System Science, University of California, Irvine (USA). Length: 15 days.
