Data from expedition Petermann, off North Greenland, 2015

Martin Jakobsson

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.

With 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.

The expedition started and ended in Thule Airbase, Greenland, and lasted from July 28 to September 2, 2015.

Comments

The expedition focused on past variations of the ocean-ice-climate-sea level system to assess how the coupled system has responded to changing climate. Interagency and international collaborations included the US National Science Foundation (NSF), The Ocean Melting Greenland (OMG) project of US National Aeronautics and Space Administration (NASA), the British Antarctic Survey, University NAVSTAR Consortium (UNAVCO), the Polar Geospatial Center (PGC), the Swedish Polar Research Secretariat, and the Geological Survey of Denmark and Greenland. The Swedish Polar Secretariat and US National Science Foundation (NSF) supported the expedition logistically and financially.
