Representations of present (top) and past (bottom) elevation of the Antarctic ice sheet

Satellite elevation data and a variety of geological records are combined to portray the surface topography of the Antarctic Ice Sheet near the Ross Ice Shelf. Above, a digital elevation model derived from satellite data shows the ice sheet today. By synthesizing various geological records, scientists have also estimated how the ice sheet is thought to have looked 20,000 years ago (bottom) at the time of the last maximum extent of glatiation. In West Antarctica, the ice sheet is most vulnerable to future change.
