抄録

A newly developed radio-echo sounder mounted on an oversnow-vehicle was used in the Shirase Glacier drainage area in 1992, obtained the maximum ice thickness of 3520m around the ice divide Dome Fuji (Dome F : 77°19'S, 39°42'E, 3810m a. s. l.). The bedrock topography of the summit area of Dome F was basin-like and internal ice distortion was not discernible because layer structures were parallel to both the ice sheet surface and the bedrock surface. The bedrock topography and internal structure were also measured from Dome F to the coast (Station S16 at 69°02'S, 40°03'E). The elevation of bedrock in the inland area was about 500m a.s.l. and the ice layers were parallel to the bedrock; between S16 and MD164 (ca. 440km south of S16) the bedrock elevation was nearly at the sea level and the internal ice structure was complex.
