Data from expedition LOMROG, Lomonosov Ridge, Arctic Ocean, 2007

Martin Jakobsson, Christian Marcussen

The LOMROG (Lomonosov Ridge off Greenland) 2007 expedition was carried out during summer of 2007. The expedition worked in the central Arctic Ocean over sections of the southern Lomonosov Ridge off Northern Greenland, the Morris Jesup Rise and Yermak Plateu.

With the Swedish icebreaker Oden serving as the research platform, a range of scientific investigations were made. The main scientific goal was to map and core the southern Lomonosov Ridge off Greenland and decipher the current flow across the ridge, specifically the pathway of intermediate Atlantic water. Data provided in the database here comprise processed multibeam bathymetry.

The expedition started in Tromsø, Norway, August 12 and ended in Longyearbyen, Svalbard, September 17, 2007.

Comments

This was a Swedish/Danish collaboration project with participating scientists also from Canada, Finland, and USA. With Swedish icebreaker Oden supported by the Russian nuclear icebreaker 50 Let Pobedy, LOMROG reached the southernmost tip of the Lomonosov Ridge off Greenland. The logistics of the expedition was supported by the Swedish Polar Secretariat, in collaboration with the Swedish Maritime Administration.

The expedition constituted a project within the Arctic Palaeoclimate and its Extremes (APEX) research network programme endorsed by the International Arctic Science Committee (IASC) and the ICSU/WMO Joint Committee for the International Polar Year 2007/2008 (IPY).
