RES Signatures of Ice Bottom Near to Dome C (Antarctica)
Abstract—Geophysical surveys have played a fundamental role in glaciology, climatology, and geology studies conducted at and around the site of the EPICA Dome C Ice Core (Antarctica). Analysis of radio-echo sounding (RES) data collected during the 2009 and 2011 Italian Antarctic Expeditions, in the...
