3-D glacial flow

Abstract: Synthetic-aperture radar can be used by satellites to map movements in the surface of the Earth -- at faults, near volcanoes or on glaciers. A new refinement of the technique exploits the varying ‘look’ angles of ascending and descending satellite orbits to make full 3D maps of glacier flow. This method can be used, for example, to directly measure volume changes of ice sheets.
