| Abstract: | Radio echo sounding (RES) measurements were collected from 1995 to 2003 during Italian Antarctic expeditions over the Vostok-Dome C region. The data collected allow for the reconstruction of a bedrock elevation map between the Belgica Highlands and the Aurora Subglacial Basin (112.0ø - 124.0ø E; 74.0ø - 78.0ø S). Moreover, analysis of the RES data has revealed one of the thickest ice covers in Antarctica (4755 Ø 16 m; 118.321ø E, 76.059ø S) as well as five new subglacial lakes. |
