The results show that the ice sheet extended onto the outer shelf.
Radiocarbon dates indicate a diachronous retreat from each drainage area.
Where crystalline bedrock comprises the substrate, ice followed the structural grain of the bedrock, deposited little sediment, and eroded the underlying bedrock. Where ice flowed over relatively soft sedimentary strata that were more easily eroded, the direction of ice flow was more directly offshore and depositional features characterize the seafloor. The different geological substrates are interpreted to have exerted a fundamental control on the behavior of past ice sheets. The drumlin areas are thus interpreted to be the location of ice acceleration. The next phase of this project focuses on the Antarctic Peninsula region.
