Kangerdlugssuaq glacier in Greenland

The Kangerdlugssuaq glacier and its ice stream are pictured in this image, acquired on September 19, 2012 by Landsat-7. It is the largest outlet glacier on Greenland's east coast, shedding ice into the surrounding oceans.

The recent data from satellite observations has revealed that over the past 20 years the ice melting in Greenland and Antarctica has contributed about 11mm to the global sea-level rise.

This image clearly shows the glacier's calving front, where ice breaks away, shedding hundreds of icebergs into the oceans.
