The internal flow and movement of a continental-scale ice sheet under its own weight, governed by ice deformation, basal sliding where meltwater lubricates the bed, and the discharge of ice through fast-moving outlet glaciers and ice streams. Understanding ice sheet dynamics is central to projecting how the Antarctic and Greenland ice sheets will respond to a warming climate.
