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.
