Annals of Glaciology 50(51) 2009 35 First results from radar profiles collected along the US-ITASE traverse from Taylor Dome to South Pole (2006–2008)
ABSTRACT. The 2006/07 and 2007/08 US-ITASE traverses from Taylor Dome to South Pole in East Antarctica provided opportunities to survey the subglacial and englacial environments using 3 MHz and 200 MHz radar. We present first results of these new ground-based radar data. A prominent basal deformatio...
