Collaborative Research: Subglacial Controls on Greenland Ice Sheet Marginal Acceleration
Funds are provided to examine the nature and cause of short-term ice sheet velocity changes. The work field would occur near Swiss Camp, Greenland and focus on the interactions between the ice sheet, the atmosphere and the bed through an integrated observational approach which involves borehole geo-...
