Statement: Calving Event at Jacobshavn Glacier

Abstract: Jacobshavn Glacier is one of the largest tide-water glaciers of Greenland. It is located on the West-coast, and drains into Disco Bay. The movie shows a calving event recorded on the 5th of June, 2007. Tremendous ice blocks calve off the active calving front of the glacier. The glacier always moves fast; at about 20m /day, and calving happens continously. Amundson et al., report 32 large events within 1 year, mostly in the period May to August. This event is gigantic, to give an idea of scale; the calving front above water is ~100m high, below water there is another 900m hidden. The blocks that break off are about 1000m wide and a few 100m in the downflow direction. The triangular block that you see overtopple in this movie sticks 200 m out of the water!
