Late Quaternary ice sheet dynamics and deglaciation history of the West Antarctic Ice Sheet in the Amundsen Sea Embayment: Preliminary results from recent research cruises
The threat, in terms of sea level rise, posed by the potential rapid deglaciation of West Antarctica means there is an urgent need to know more about the speed and style of marine ice sheet retreat. Quaternary deglacial events recorded in marine sediments provide an opportunity to understand the fut...
