[{"name":"oden-petermann-2015-expedition-1","title":"Data from expedition Petermann, off North Greenland, 2015","summary":"The Petermann 2015 expedition was carried out during summer 2015 in the Nares Strait off Northwestern Greenland. The main target was the Petermann Fjord where Petermann Glacier drains the northwestern sector of the Northern Greenland Ice Sheet. The adjacent area of Hall Basin of Nares Strait as well as the entrance to Archer Fjord on the Canadian side of Nares Strait were also surveyed during the expedition.\r\n\r\nWith the Swedish icebreaker Oden serving as the research platform, a range of scientific investigations were made. The main overall scientific goal was to increase our knowledge on the marine cryosphere and ecosystem of Northwest Greenland, specifically changes that may occur in a warming climate. In specific focus was the dynamics of Petermann Glacier, draining into Petermann Fjord. Data provided in the database here comprise processed multibeam bathymetry and hydrography.\r\n\r\nThe expedition started and ended in Thule Airbase, Greenland, and lasted from July 28 to September 2, 2015.","citations":"1.\tReusche, M.
