Summary

A new Canadian radar satellite is giving polar researchers the first highly detailed map of Antarctica and its ice sheet, revealing unexpected ice flows and a heavily textured surface in areas that were thought to be largely featureless. Researchers say the data offer clues to the topography of the continent hidden under the ice. Comparisons with earlier images could also trace the retreat of the ice shelves and glaciers, a possible sign of global warming.
