Summary
Changes in the ice load since the time of the Last Glacial Maximum (LGM) contribute to the present-day vertical motion of the Antarctic continent. The observation of these motions will reveal information on the ice load history. Predictions of uplift rates along a transect across the Lambert Glacier region, East Antarctica, from the coast to the southermost rock outcrops of the Prince Charles Mountains have been computed for three deglaciation scenarios. The relative vertical velocities between sites on the transect are -7 to +7 mm/yr and are large enough to be detected from continuous GPS observations taken at permanent sites over several years. When available, such information will discriminate between the currently available models for deglaciation of East Antarctica.
