First complete map of the speed and direction of ice flow in Antarctica, derived from radar interferometric data from the Japan Aerospace Exploration Agency's ALOS PALSAR, the European Space Agency's ... Envisat ASAR and ERS-1/2, and the Canadian Space Agency's RADARSAT-2 spacecraft. The color-coded satellite data are overlaid on a mosaic of Antarctica created with data from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra spacecraft. Pixel spacing is 984 feet (300 meters). The thick black lines delineate major ice divides. Subglacial lakes in Antarctica's interior are also outlined in black. Thick black lines along the coast indicate ice sheet grounding lines.
