The view from the flight deck of a US Air Force C-17 cargo plane on the way to Antarctica. Matt Siegfried, who recently received his PhD from Scripps Institution of Oceanography at UC San Diego, is blogging from the field as part of ROSETTA-Ice, a National Science Foundation-funded survey of the Ross Ice Shelf, a France-sized glacier that floats on the Ross Sea. Scientists will be determining the structure of the ice shelf and of the seafloor beneath it by detecting tiny changes in gravity that give clues to the elevations of ice and land masses. They will use the information to determine how the ice shelf has responded to climate change in the past and how it is now.
