Description

This is the first map of ice velocity over the entire continent of Antarctica. It is derived from ALOS PALSAR, Envisat ASAR, Radarsat-2, ERS-1 and ERS-2 satellite radar interferometry overlaid on a MODIS mosaic of Antarctica. These new findings are critical to measuring the global impact to sea-level rise resulting from ice flowing into the ocean.
