Time-lapse video of ice discharge at the front of Jakobshavn
Glacier near Ilulissat, Greenland
This animation portrays the changes occurring in the surface elevation of the ice sheet since 2003 in three drainage regions: the southeast, the northeast and the Jakobshavn
The giant glacier Jakobshavn
Isbrae, for instance, accelerated from 9.4 kilometers per year in 2000 to 12.6 kilometers per year in 2003.
Especially prolific is the coastline's northern half, extending from Humboldt Glacier on Kane Basin down to Jakobshavn
Glacier on Disk [empty set] Bay.
During a four-week expedition to the Jakobshavn
Isbrae glacier in western Greenland last summer, Marco Tedesco of the City College of New York and his team recorded data on air temperatures, wind speed, exposed ice and its movement, the emergence of streams and lakes of melt water on the surface, and the water's eventual draining away beneath the glacier.
The conclusion stems from research on Jakobshavn
Isbrae--a tongue of ice extending out to sea from Greenland's west coast--published in Quaternary Science Reviews.
One of the fastest-moving glaciers in the world, called Jakobshavn
(pronounced YAH-kubs-hav' un), is on Greenland's west coast.
Acceleration of Jakobshavn
Isbrae triggered by warm subsurface ocean waters.
The 318-berth Fram takes passengers to Eqip Sermia Glacier, a wall of ice that calves into the sea; icebergs in Disko Bay and at the mouth of Jakobshavn
Ice Fjord, a World Heritage Site; and Jakobshavn
Glacier, the worldOs most active glacier.
But it's warm enough for the enormous Jakobshavn
(yahcub-SAH-ven) glacier to slightly melt.
