The Northwest Passage (NWP) is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Arctic Archipelago of Canada. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP). The various islands of the archipelago are separated from one another and from Mainland Canada by a series of Arctic waterways collectively known as the Northwest Passages, Northwestern Passages or the Canadian Internal Waters.
Hudson Strait in Nunavut links the Atlantic Ocean and the Labrador Sea to Hudson Bay in Canada. This strait lies between Baffin Island and Nunavik, with its eastern entrance marked by Cape Chidley in Newfoundland and Labrador and Nunavut and Resolution Island, off Baffin Island. The strait is about 750 km (470 mi) long with an average width of 125 km (78 mi), varying from 70 km (43 mi) at the eastern entrance to 240 km (150 mi) at Deception Bay.
Baffin Bay, located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the ice cover and high density of floating ice and icebergs in the open areas. However, a polynya of about 80,000 km2 (31,000 sq mi), known as the North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region.
