Time-lapse animation of images of the Kangerdlugssuaq ice stream taken from March to May 2011. The animation shows the ice stream advancing steadily at a speed of about 35 m per day, until a 9 sq km piece of the glacier broke into icebergs during 19–22 May. (via ESA)

Mosaic of the Arctic (by NASA Goddard Photo and Video) On June 30, 2011 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite made multiple passes over the Arctic, capturing a true-color image of the summer lands and sea-ice near the North Pole on each pass. Individual images were then pieced together to create a large mosaic of the area, which gives a broader, circumpolar, view that would not be possible with individual images. Credit: NASA/GSFC/Jeff Schmaltz/MODIS Land Rapid Response Team.

Earth from Space: Summer ice retreat (by europeanspaceagency) In this image, acquired on 23 June 2011, Envisat captures part of Greenland’s ice sheet and east coast as the winter sea ice recedes. Covering roughly 80% of the surface of Greenland, this ice sheet is the second largest body of ice in the world, after that of Antarctica. Credits: ESA.

Earth from Space: Iceberg Alley (by europeanspaceagency)   A large chunk of the massive iceberg (centre) that broke off Greenland’s Petermann Glacier in August 2010 is featured floating in the Labrador Sea off the eastern coast of Labrador in this Envisat image, acquired on 4 May 2011 by the Medium Resolution Imaging Spectrometer (MERIS) instrument. More than 1000 icebergs flow off southern Labrador and northern Newfoundland from late May to late June, earning the area the nickname ‘Iceberg Alley’. Ice floes (top) are visible drifting southwards in the sea. White swirls indicate drift of the small pieces of ice in response to ocean vortexes, or ‘eddies’, and are an expression of the ocean surface currents. Credits: ESA.

May 2011 Nature Geoscience cover: Submarine melting has been suggested as a trigger for the widespread acceleration of tidewater glaciers in Greenland. An analysis of oceanographic data from the fjord off Helheim Glacier, Greenland, suggests the presence of light Arctic and dense Atlantic waters in the fjord and that the melting circulation is more complex than thought. The image shows the Greenland ice sheet margin where it meets Sermilik Fjord, August 2009. Photo © Nick Cobbing/Greenpeace.
