Abstract New diatom-biostratigraphic age data derived from piston core were used to constrain the chronology for a seismic-based interpretation of West Antarctic Ice Sheet (WAIS) advance and retreat from the North Basin outer shelf in western Ross Sea. The data demonstrates that grounded ice occupied the outer shelf on at least ten occasions during the last 2.0 Ma of the Pleistocene. Although the biostratigraphic resolution is low, the constraints permit correlations to coeval section recently… CONTINUE READING
