Greenland is isostatically depressed by the Greenland ice sheet such that parts of the bedrock surface in the interior are below sea level.Projected future equilibrium states of Greenland ice sheet[1]
Isostatic depression is the sinking of large parts of the Earth's crust into the asthenosphere caused by a heavy weight placed on the Earth's surface, often glacial ice during continentalglaciation.[2] Isostatic depression and isostatic rebound occur at rates of centimeters per year. Greenland is an example of an isostatically depressed region.
