Jakobshavn Isbræ

Jakobshavn Isbræ, also known as the Jakobshavn Glacier and Sermeq Kujalleq (in Greenlandic) is a large outlet glacier in West Greenland. It is located near the Greenlandic town of Ilulissat (Danish: Jakobshavn) and ends at the sea in the Ilulissat Icefjord. Jakobshavn Isbræ drains 6.5% of the Greenland ice sheet and produces around 10% of all Greenland icebergs. Some 35 billion tonnes of icebergs calve off and pass out of the fjord every year. Icebergs breaking from the glacier are often so large (up to a kilometer in height) that they are too tall to float down the fjord and lie stuck on the bottom of its shallower areas, sometimes for years, until they are broken up by the force of the glacier and icebergs further up the fjord....
