image: The fully equipped Twin Otter on skis takes off from AGAP-S camp at 3,500 m heading north to survey over Dome A. Four radar antennae can be seen hanging down on each wing. Energy was transmitted from the four antenna on the left wing, through the ice sheet where it reflected off layers in the ice and the hidden mountains. The returning energy was received on the four antennae on the right wing. The pods on the ends of the wings contain the magnetometers. The gravity meter and the laser altimeter are mounting inside the aircraft. This image relates to an article that appeared in the March 3, 2011, issue of Science Express, published by AAAS. The study, by Dr. Robin Bell, at Lamont-Doherty Earth Observatory of Columbia University in Palisades, N.Y., and colleagues was titled, "Widespread, Persistent Thickening of the East Antarctic Ice Sheet by Freezing from the Base." view more
