NASA | Measuring Elevation Changes on the Greenland Ice Sheet

From the creator

Since the late 1970's, NASA has been monitoring changes in the Greenland Ice Sheet. Recent analysis of data from both the ICESat satellite and an ongoing airborne mission called Operation IceBridge show us how the surface elevation of the ice sheet has changed. This animation portrays the changes occurring in the surface elevation of the ice sheet since 2003 in three drainage regions: the southeast, the northeast and the Jakobshavn regions. In each region, the time advances to show the accumulated change in elevation from 2003 through 2012.
