Routing of meltwater from the Laurentide Ice Sheet during the Younger Dryas cold episode

Oxygen isotope and accelerator radiocarbon measurments on planktonic foraminifera from Orca Basin core EN32-PC4, which reveal a significant reduction in meltwater flow through the Mississippi River to the Gulf of Mexico from about 11,200 to 10,000 radiocarbon years ago are presented.
