There are over 200 glaciers around the coast of Greenland, each providing a direct connection between the ice sheet and the ocean. The ice flows in huge ice streams from the interior and drains via the numerous glaciers - thereby carrying loads of freshwater into the ocean. Conversely, changes in the ocean also have an impact on the Greenland Ice Sheet: Increased water temperatures lead to increased melting at numerous glaciers, which calving fronts extend hundreds of meters into the water. Therefore, the ocean contributes significantly to the rapid retreat of the glaciers - and thus to an increased drainage of the ice from the interior into the ocean.
