Deglacial floods in the Beaufort Sea preceded Younger Dryas cooling
L. Keigwin, S. Klotsko, N. Zhao, B. Reilly, L. Giosan, N. Driscoll
Geology
Nature Geoscience

2018
A period of cooling about 13,000 years ago interrupted about 2,000 years of deglacial warming. Known as the Younger Dryas (YD), the event is thought to have resulted from a slowdown of the Atlantic… Expand

Lake Agassiz during the Younger Dryas
J. Teller
GeologyQuaternary Research
2013
Lake Agassiz was ponded on the northward-sloping surface of the Hudson Bay and Arctic Ocean basins, as the Laurentide Ice Sheet retreated. The level of Lake Agassiz abruptly fell ~ 12.9 cal (11 14C)… Expand

Catastrophic glacial-lake outburst flooding of the Patagonian Ice Sheet
G. Benito, V. Thorndycraft
Geology
2020
Abstract Reconstructing the magnitude and timing of catastrophic drainage of proglacial lakes during Late Quaternary deglaciation of palaeo-ice sheets is important for understanding rates of… Expand

Arctic sea ice export as a driver of deglacial climate
A. Condron, A. Joyce, R. Bradley
Geology
2020
A widespread theory in paleoclimatology suggests that changes in freshwater discharge to the Nordic (Greenland, Norwegian, and Icelandic) Seas from ice sheets and proglacial lakes over North America… Expand

2012
TLDR
It is concluded that meltwater discharge from the Arctic, rather than the St. Lawrence Valley, was more likely to have triggered the Younger Dryas cooling. Expand

Opening of glacial Lake Agassiz’s eastern outlets by the start of the Younger Dryas cold period
David J. Leydet, David J. Leydet, +10 authors M. Caffee
Geology
2018
The Younger Dryas (12.9 ± 0.1 to 11.7 ± 0.1 ka) was a return to cold conditions in the Northern Hemisphere during the last deglaciation. This climatic event was hypothesized to have been caused by a… Expand
Enhanced sea-ice export from the Arctic during the Younger Dryas.
Christelle Not, C. Hillaire‐Marcel
Geology, MedicineNature communications
2012
TLDR
The hypothesis of a glacial drainage event in the Canadian Arctic area, at the onset of the Younger Dryas, enhancing sea-ice production and drifting through the Arctic, then export through Fram Strait, towards Atlantic meridional overturning circulation sites of the northern North Atlantic is supported.

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

Geology

1989
ROOTH1 proposed that the Younger Dryas cold episode, which chilled the North Atlantic region from 11,000 to 10,000 yr BP, was initiated by a diversion of meltwater from the Mississippi drainage to… Expand
Arctic freshwater forcing of the Younger Dryas cold reversal
L. Tarasov, W. Peltier
Environmental Science, GeologyNature
2005
TLDR
An ensemble of simulations of the drainage chronology of the North American ice sheet is analysed in order to identify the geographical release points of freshwater forcing during deglaciation and finds that the largest combined meltwater/iceberg discharge was directed into the Arctic Ocean. Expand

Geology
2002
The Preboreal oscillation (PBO) has been attributed to increased meltwater, but the source of the meltwater and causative mechanism of the PBO has remained elusive. Here we attribute the source to a… Expand
