3 MHz Deep Radar Measurements South Pole - Troll Station (IPY 2008-2009)
3 MHz Deep Radar Measurements along the route of the Norwegian – U.S. Scientific Traverse of East Antarctica 2008-2009. The primary goal of the deep radar was to measure ice thickness along the traverse route. In conjunction with surface elevation, the data also gives topography at the base of the i...
