Linking subglacial meltwater through the eastern Great Lakes, Ontario and New York (at the time of the Atlantic Heinrich 1 event) with a meltwater flood in the Gulf of Mexico about 13.5 ka (16.2 cal ka): M183-2/8181E-PDF

"The events and flows described in this Open File fit a scenario in which Laurentide Ice Sheet instability, associated with the H1 event of iceberg discharge to the North Atlantic Ocean, facilitated regional subglacial meltwater flows, first southward, then west-southwestward, leading to rapid transport of meltwater through the eastern Great Lake basins, then southward via the Mississippi River valley to the Gulf of Mexico about 13.6-13.4 (16.4-16.1 cal) ka. The meltwater flows discharged to the Gulf of Mexico where they have been detected by highly negative delta-18O composition of foraminiferal tests”--Summary provided by publisher.
