Jakobshavn Glacier as Seen by ATM

April 17, 2013
Plot of preliminary Airborne Topographic Mapper T4 wide scan data of Greenland’s Jakobshavn Glacier. Warmer colors indicate higher ice elevation and the transition from warm to cool colors shows the glaciers calving front, where ice breaks off of the glacier. The southernmost swath shows data from the Apr. 4 IceBridge flight and the two northernmost swaths show the Jakobshavn calving front six days later on Apr. 10. The difference between the two days shows a loss of about 200 meters of ice. Credit: NASA / ATM team
