North Atlantic Deep Water North Atlantic Deep Water formation has been dramatically reduced at times during the past (such as during the Younger Dryas or during Heinrich events), and that this might correlate with a decrease in the strength of the Gulf Stream and the North Atlantic drift, in turn cooling the climate of northwestern Europe. There is concern that global warming might cause this to happen again. It is also hypothesized that during the Last Glacial Maximum (LGM), NADW was replaced with an analogous watermass that occupied a shallower depth known as Glacial North Atlantic Intermediate Water (GNAIW).

Hudson Strait expedition led by Robert Bylot and William Baffin in 1616. Hudson Strait links the northern seaports of Manitoba and Ontario with the Atlantic Ocean. The Strait could serve as an eastern entrance to the Northwest Passage if it were not for ice in the Fury and Hecla Strait south of western Baffin Island.
