Calving

Draining about 7 % of the entire ice sheet, Jakobshavn Isbræ is one of Greenland’s largest outlet glaciers. Near its terminus it flows close to 30 meters per day and has a thickness of approximately 1’000 m. The glacier used to terminate in a floating tongue. However, since the 1990’s the glacier has undergone a > 10 km retreat during which this tongue was lost.
