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 meridional overturning circulation in response to a sudden flood of Laurentide Ice Sheet meltwater that reached the Nordic Seas. Oxygen isotope evidence for a local source of meltwater to the open western North Atlantic from the Gulf of St Lawrence has been lacking. Here we report that the eastern…

The role of Northeast Pacific meltwater events in deglacial climate change
It is infer that Pacific meltwater fluxes contributed to net Northern Hemisphere cooling prior to North Atlantic Heinrich Events, and again during the Younger Dryas stadial, and underscores the importance of changes in North Pacific freshwater fluxes and circulation in deglacial climate events.
Deglacial to Holocene variability in surface water characteristics and major floods in the Beaufort Sea
Surface water characteristics of the Beaufort Sea have global climate implications during the last deglaciation and the Holocene, as (1) sea ice is a critical component of the climate system and (2)
Labrador Sea freshening at 8.5 ka BP caused by Hudson Bay Ice Saddle collapse
New evidence is presented for a severe Labrador shelfwater freshening 8500 years ago that was caused by the Hudson Bay Ice Saddle collapse following a warming in subsurface waters.
Glacial-interglacial sedimentation and paleocirculation at the Northwind Ridge, western Arctic Ocean
Abstract Sediment cores from the Northwind Ridge north of the Arctic Chukchi-Alaskan margin were analyzed for a suite of stratigraphic and provenance proxies. Based on the correlation to previously
Deglacial bottom water warming intensified Arctic methane seepage in the NW Barents Sea
Changes in the Arctic climate-ocean system can rapidly impact carbon cycling and cryosphere. Methane release from the seafloor has been widespread in the Barents Sea since the last deglaciation,
Ion concentrations in ice wedges: An innovative approach to reconstruct past climate variability
Abstract For atmospheric gases and aerosols, snow and ice provide a useful archive of paleoenvironmental history. In the northern hemisphere, this archive has been largely limited to Greenland ice,
Megaflooding associated with glacial Lake Agassiz
Abstract Significant baseline and episodic megaflooding from glacial Lake Agassiz was routed to the south, east and north coasts of North America over the lake’s nearly 6000 year history. The five
Sea level fingerprinting of the Bering Strait flooding history detects the source of the Younger Dryas climate event
It is demonstrated that their reconciliation requires a substantial melting of the Cordilleran and western Laurentide Ice Sheet from 13,000 to 11,500 years ago, which provides a freshwater source for the widely debated Younger Dryas cold episode.
Postglacial paleoceanography and paleoenvironments in the northwestern Barents Sea
Abstract The Barents Sea offers a suitable location for documenting advection of warm and saline Atlantic Water (AW) into the Arctic and its impact on deglaciation and postglacial conditions. We
A multi-proxy study of changing environmental conditions in a Younger Dryas sequence in southwestern Manitoba, Canada, and evidence for an extraterrestrial event
Abstract Multi-proxy analyses of a sequence spanning the Younger Dryas (YD) in the Glacial Lake Hind basin of Manitoba provides insight into regional paleohydrology and paleovegetation of meltwater


Identification of Younger Dryas outburst flood path from Lake Agassiz to the Arctic Ocean
A large flood into the Arctic Ocean at the start of the Younger Dryas leads us to reject the widespread view that Agassiz overflow at this time was solely eastward into the North Atlantic Ocean.
Reduced meltwater outflow from the Laurentide ice margin during the Younger Dryas
THE cause of the Younger Dryas cold event, which interrupted the last deglaciation, is still a matter of debate1. A prevalent hypothesis, proposed by Broecker et al.2 is that the abrupt climate
Routing of meltwater from the Laurentide Ice Sheet during the Younger Dryas cold episode
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
Arctic freshwater forcing of the Younger Dryas cold reversal
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.
Dynamics of the Laurentide ice sheet during the last deglaciation: evidence from the Gulf of Mexico
Oxygen isotopic analyses of planktonic foraminifera from an anoxic basin (Orca Basin) in the northwestern Gulf of Mexico record a negative isotopic anomaly of 3.6‰ from 16,500 to 11,600 years before
Meltwater routing and the Younger Dryas
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.
Geochemical proxies of North American freshwater routing during the Younger Dryas cold event
The Younger Dryas cold interval represents a time when much of the Northern Hemisphere cooled from ≈12.9 to 11.5 kiloyears B.P. The cause of this event, which has long been viewed as the canonical

The Younger Dryas cold reversal during the last glacial termination is one of the most abrupt climate change events observed in the Northern Hemisphere. Analyses of varved lake sediments from western
