| Summary: | The LOMROG II expedition was carried out in the summer of 2009 by the Danish Continental Shelf Project in cooperation with the Swedish Polar Research Secretariat and the Swedish Maritime Administration. The expedition was a follow-up to LOMROG, which was conducted in 2007. The Swedish icebreaker Oden served as the research platform, while the actual research areas was selected based on the prevailing ice situation, particularly in the area around the North Pole. In 2009 Oden operated without the assistance of another icebreaker. The expedition focused on the areas around the North Pole, although the area northeast of Greenland also was included. The researchers were particularly interested in the Lomonosov Ridge, a mountain ridge on the ocean floor. To break through the nearly impenetrable icepack, Oden was assisted by one of the world’s most powerful icebreakers, the Russian 50 Let Pobedy.The Danish researchers mainly worked on the Continental Shelf Project, which is affiliated with the UN Convention on the Law of the Sea (UNCLOS) regarding national claims to the ocean floor. Using advanced multi-beam 3D echo sounding, seismology, and water and sediment samples, the researchers gathered information about the appearance and structure of the ocean floor. A group of marine geologists from Stockholm University also took part in the Danish project. A sequence of sediment cores was collected from the slope of the Lomonosov Ridge as part of a project called ”Reconstructing Central Arctic Ocean Paleoceanography Using Sediment Cores from the Lomonosov Ridge”. The sediment cores could provide answers to questions about how the dynamics of the inland ice sheets have affected the global climate. The expedition started and ended in Longyearbyen in Svalbard. Purpose: The study’s purpose was to collect meteorological, oceanographic and ship data during the Danish-Swedish expedition Lomonosov Ridge off Greenland II. These data were collected onboard the icebreaker Oden during the Lomonosov Ridge off Greenland II (LOMROG II) ...
