Greenland Ice Sheet Velocity Structure Changes

Rignot & Kanagaratnam used satellite radar interferometry observations of Greenland to detect widespread acceleration of glaciers below 66o north between 1996 and 2000, which expanded rapidly to 70o north in 2005. In the west, and particularly the east, accelerated discharge of ice doubled the mass deficit of the ice sheet in the last decade from 90 to 220 km3 per year. The sea level rise contributable to the Greenland ice sheet will continue to increase as more glaciers accelerate further north.
