Jakobshavn Glacial Floe

Visualizations by Alex Kekesi Released on December 1, 2004
Jakobshavn Isbrae holds the record as Greenland's fastest moving glacier and major contributor to the mass balance of the continental ice sheet. Starting in late 2000, following a period of slowing down in the mid 1990s, the glacier showed significant acceleration and nearly doubled its discharge of ice.

As the Jakobshavn Glacier discharges ice from its mouth, tributary ice streams show signs of acceleration. This series of Landsat images from 2002 shows rapid migration of ice features downstream, triggering adjacent land ice to accelerate downslope. A sequence of 7 Landsat images cycles at the end of the animation repeatedly to better see the flow.
