Summary
Abstract: The Antarctic megadune research was conducted during two field seasons, one in
November 2002 and the other in December 2003 through January 2004. The megadune
field site is located on the East Antarctic Plateau, southeast of Vostok
station. The objectives of this multi-facetted research are to determine the
physical characteristics of the firn across the dunes including ... View entire text
