Fabric Analysis of Surface Ice near Casey Range, East Antarctica
Abstract Forbes Glacier, one of the outlet ice streams from the Antarctic ice sheet, is located 20 km west of Mawson, Mac.Robertson Land, east Antarctica. In the uppermost part of the glacier near Casey Range, the velocity at the centre of the glacier is 59 m year −1 and the strain-rate at seven str...
