In October 2006, a study using data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites discussed the condition of the Greenland Ice Sheet. The study determined that, although the ice sheet had gained some mass in the interior, it had lost considerably more mass along the perimeter, particularly southeastern Greenland.
This pair of images shows the retreat of the Sermersuaq (Humboldt) Glacier in northwestern Greenland between 2000 and 2008. Sermersuaq Glacier is the widest tidewater glacier in the Northern Hemisphere.
Where once two streams of ice merged in Greenland’s Jakobshavn Glacier, today there is division and a complex surface riddled with crevasses and melt ponds.
