Description :
Two widely different hypotheses have been proposed for the late Tertiary glacial history of East Antarctica. These invoke ice sheet reconstructions ranging from severe glaciation completely burying the Transantarctic Mountains to a situation , in which an unstable East Antarctic Ice Sheet repeatedly collapses to produce ice-free conditions over interior basins. Experiments were performed with a 3-D model of the Antarctic Ice Sheet to determine the ice sheet geometries to be expected under various kinds of climatic conditions and the physical mechanism that may be involved.
