New crack

Ian Joughin of the Polar Science Center Applied Physics Lab at the University of Washington (UW), examines a large, angular crack in the ice during a 2008 expedition to Greenland. A team of four scientists from the Woods Hole Oceanographic Institution and UW returned for their third year of study to better understand how Greenland’s ice sheet is disappearing. Learn more about the expedition on the Polar Discovery web site.
