COLLABORATIVE RESEARCH: Response of the Northwest Greenland Cryosphere to Holocene Climate Change
The aim of this collaborative project between investigators at three universities is to develop records of past climate in northwest (NW) Greenland and synthesize them with records of the position of ice margin to evaluate the response of the Greenland Ice Sheet to past warm periods, such as the Hol...

The aim of this collaborative project between investigators at three universities is to develop records of past climate in northwest (NW) Greenland and synthesize them with records of the position of ice margin to evaluate the response of the Greenland Ice Sheet to past warm periods, such as the Holocene Climatic Optimum (approximately 5 to 9 thousand years ago). Recent studies suggest that rapid ice loss is expanding northwards into NW Greenland, as demonstrated by the dramatic August, 2010 calving event from Petermann Glacier. However, little paleoclimate and ice sheet research has been conducted in NW Greenland, despite the proximity to a logistics center at Thule Air Base.
