Summary
Abstract: The Jakobshavn Isbrae glacier, also known as Sermeq Kujalleq, is located on the west coast of Greenland at Latitude 69 degrees N. The ice front, where the glacier calves into the sea, receded more than 40 km between 1850 and 2010. Between 1850 and 1964 the ice front retreated at a steady rate of about 0.3 km/yr, after which it occupied approximately the same location until 2001, receding 10km in three years. After 2005 the single icefront had retreated enough to split into distinct fronts for the smaller, northern tributary and the main southern trunk. The icestream flows in a deep trough which ends near the current glacier terminus. The bedrock topography is expected to stabilize the location of the icefront for the near future as the glacier continues to drawn ice from Greenland's interior. The movement of ice from glaciers on land into the ocean contributes to a rise in sea level. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area.

This image is generated with an orthographic camera set to view the range from 51.372 W longitude to 49.212 W and from 68.94 N latitude to 69.39 N. The Landsat image shown in the background is a false color image of data collected on July 29, 2009.
