Abstract
In the evening of 12 September the research icebreaker Polarstern left the port of Tromsø (Norway). On board there were scientists from seven nations covering the range from physical oceanography, geochemistry, glaciology, geodesy, geology, geophysics, atmospheric physics and chemistry as well as marine biology and biogeochemistry. The aim of the “Greenland ice sheet/ocean interaction” (GRISO) expedition is to unravel the complex physical interactions between the ocean and the ice sheet of Northeast Greenland, as well as their implications for the marine ecosystem (see Fig. 1.1 for cruise track).

Initial commit
Knut and Alice Wallenberg Foundation (KAW) and Swedish Research Council (VR) financed the Oden multibeam system and the installation was financed by the Swedish Maritime Administration. The Oden expeditions were organized by the Swedish Polar Research Secretariat. This Mapping Repository is a part of the Bert Bolin Centre for Climate Research data archive.
