Unlike the great ice sheet of Antarctica, the Greenland ice sheet is melting both on its surface and also at outlet glaciers that drain the ice sheet's mass through deep fjords, where these glaciers extend out into the ocean and often terminate in dynamic calving fronts, giving up gigaton - sized icebergs at times.

Alaska's glaciers contributed to one third of the world's ice sheet losses from 2005 to 2010, but a new study suggests melting, not calving as shown here, contributed to the most loss.
