Abstract

The research strategy of the AA. combines geologic mapping and soil studies of drift sheets in ice-free areas. They differentiated drift sheets by changes in surface morphology, surface boulder weathering and soil development. The AA. conclude that the Beardmore drift limit is late Wisconsin (isotope stage 2) and the Meyer limit Stage 6 in age. The Beardmore and Meyer drift sheets represent thickening of the Beardmore Glacier in response to Ross Ice Shelf grounding during the last two global glaciations. Ice-shelf grounding most likely resulted from lowered sea level and/or basal melting
