Summary
Abstract: The history of meltwater flow from the Laurentide Ice Sheet to the Gulf of
Mexico during the last deglaciation, which holds possible implications for the
cause of the Younger Dryas cold episode, is not well understood. We propose a
new chronology based on using the percentage of reworked calcareous
nannofossils in Orca Basin sediments as a proxy for erosion. The period of
greatest meltwater ... View entire text
