Contrasting Sub-ice Shelf, Subglacial and Glaciomarine Deposition at the Ross Ice Shelf Edge: Implications for the Glacial History of the Ross Sea Region, Antarctica ...
Data from cores collected at sites located in front of and beneath the Ross Ice Shelf (prior to 2000 and 2002 calving events) indicate that sub-ice shelf facies are characterized by silty, fine-grained sediment with reworked diatom species among modern assemblages. The presence of coarse material an...
