ICESat First Light Release: Antarctica, from Coast to Coast

ICESat's first topographic profiles across the continent reveal the textured surfaces of Antarctic ice sheets in unprecedented detail. The following profile spans the entire Antarctic continent from coast to coast. The transect begins near Wrigley Gulf, crosses the Ross Ice Shelf and central Antarctica, finally tapering off at the Amery Ice Shelf. The high flat area in the center of the continent is called the East Antarctic plateau.
