Cold as Ice

Scientists using NASA satellites discovered an extensive network of waterways beneath a fast-moving Antarctic ice stream that provide clues as to how "leaks" in the system affect sea level and the world's largest ice sheet. Data from the Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite, and data from the Geoscience Laser Altimeter System on NASA's Ice Cloud and Land Elevation Satellite, provided a multi-dimensional view of changes in the elevation of the icy surface above a large subglacial lake and surrounding areas during a three-year period. Those changes suggest the lake drained to the nearby ocean. For more information, visit:
