Hudson Bay, sometimes called Hudson's Bay, is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km2 (470,000 sq mi). It is located north of Ontario, west of Quebec, northeast of Manitoba, and southeast of Nunavut, but politically entirely part of Nunavut. It is an inland marginal sea of the Arctic Ocean. The Hudson Strait provides a connection between the Labrador Sea and the Atlantic Ocean in the northeast, while the Foxe Channel connects the Hudson Bay with the Arctic Ocean in the north. It drains a very large area, about 3,861,400 km2 (1,490,900 sq mi), that includes parts of southeastern Nunavut, Alberta, Saskatchewan, Ontario, Quebec, all of Manitoba, and parts of the U.S. states of North Dakota, South Dakota, Minnesota, and Montana. Hudson Bay's southern arm is called James Bay.
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 Island, in the Canadian territory of Nunavut, is the largest island in Canada, the second largest island in the Americas, and the fifth-largest island in the world. Its area is 507,451 km2 (195,928 sq mi) with a population density of 0.03/km2; the population was 13,039 according to the 2021 Canadian census; and it is located at 68°N70°W. It also contains the city of Iqaluit, which is the capital of Nunavut.
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.
Southampton Island is a large island at the entrance to Hudson Bay at Foxe Basin. One of the larger members of the Arctic Archipelago, Southampton Island is part of the Kivalliq Region in Nunavut, Canada. The area of the island is stated as 41,214 km2 (15,913 sq mi) by Statistics Canada. It is the 34th largest island in the world and Canada's ninth largest island. The only settlement on Southampton Island is Coral Harbour, called Salliq in Inuktitut.
Melville Peninsula is a large peninsula in the Canadian Arctic north of Hudson Bay. To the east is Foxe Basin and to the west the Gulf of Boothia. To the north the Fury and Hecla Strait separates it from Baffin Island. To the south Repulse Bay and Frozen Strait separate it from Southampton Island at the north end of Hudson Bay. On the southwest it is connected to the mainland by the Rae Isthmus, named after the Arctic explorer John Rae.
Lancaster Sound is a body of water in the Qikiqtaaluk Region, Nunavut, Canada. It is located between Devon Island and Baffin Island, forming the eastern entrance to the Parry Channel and the Northwest Passage. East of the sound lies Baffin Bay; to the west lies Viscount Melville Sound. Further west a traveller would enter the M'Clure Strait before heading into the Arctic Ocean.
Fury and Hecla Strait is a narrow Arctic seawater channel located in the Qikiqtaaluk Region of Nunavut, Canada.
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
The Ottawa Islands are a group of currently uninhabited islands situated in the eastern edge of Canada's Hudson Bay. The group comprises 24 small islands, located at approximately 60N 80W. The main islands include Booth Island, Bronson Island, Eddy Island, Gilmour Island, J. Gordon Island, Pattee Island, and Perley Island. The highest point is on Gilmour Island, which rises to over 1,800 ft (550 m). Located a short distance off the northwest coast of Quebec's Ungava Peninsula, they, like the other coastal islands in Hudson Bay, were historically part of the Northwest Territories, and became Crown Land upon the creation of Nunavut in 1999. Nunavik Inuit have occupied these islands since time immemorial and gained constitutionally-protected harvest and access rights under the Nunavik Inuit Land Claim Agreement signed in 2007.
The Arctic Archipelago Marine Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a marine ecozone in the Canadian Arctic, encompassing Hudson Bay, James Bay, the internal waters and some shores of the islands in the Canadian Arctic Archipelago, and the shores of the territories, northern Ontario and western Quebec. Early exploration of these waters by Europeans were conducted to find a passage to the Orient, now referred to as the Northwest Passage.
Tasiujaq formerly Murray Maxwell Bay is an uninhabited waterway in the Qikiqtaaluk Region, Nunavut, Canada. It is located in the Foxe Basin, north of Baffin Island's Siorarsuk Peninsula. Kapuiviit lies at the opening of the bay.
The Back Peninsula is a cape located on eastern Bell Peninsula, Southampton Island, in the Kivalliq Region, Nunavut, Canada. Its southern shore is part of the northern boundary of Hudson Bay. Foxe Basin is to the north. There are two large bays, Gorden Bay and Junction Bay. Bowhead whale frequent the area. The Bell Peninsula's irregular coastline is marked by Seashore Point and Expectation Point.
The bowhead whale is a species of baleen whale belonging to the family Balaenidae and is the only living representative of the genus Balaena. It is the only baleen whale endemic to the Arctic and subarctic waters, and is named after its characteristic massive triangular skull, which it uses to break through Arctic ice. Other common names of the species included the Greenland right whale, Arctic whale, steeple-top, and polar whale.
Dorset Island, or Cape Dorset Island, is one of the Canadian Arctic islands located in Hudson Strait, Nunavut, Canada. It lies off the Foxe Peninsula area of southwestern Baffin Island in the Qikiqtaaluk Region. It is serviced by an airport and a harbour.
The East Bay (Qaqsauqtuuq) Migratory Bird Sanctuary, Qaqsauqtuuq Migratory Bird Sanctuary, or Refuge d'oiseaux de la baie Est is a migratory bird sanctuary in the Kivalliq Region, Nunavut, Canada. It is located in East Bay, an arm of Hudson Bay, in southeast Southampton Island. The nearest community is Coral Harbour, 35 km (22 mi) to the west.
Nirjutiqavvik National Wildlife Area is a National Wildlife Area on Coburg Island within the Qikiqtaaluk Region, Nunavut, Canada. It is located in Baffin Bay's Lady Ann Strait between Ellesmere Island, to the north, and Devon Island to the south. The NWA includes Coburg Island and its surrounding marine area.
Seymour Island is an uninhabited island in the Qikiqtaaluk Region of northern Canada's territory of Nunavut. A member of the Berkeley Islands group, it is located approximately 30 mi (48 km) north of northern Bathurst Island. Between Seymour Island and Bathurst Island lies Helena Island. Penny Strait lies about 90 km (56 mi) to the east where open water polynyas occur.
The North Water Polynya (NOW), or Pikialasorsuaq to Inuit in Greenland and Sarvarjuaq to Inuit in Canada, is a polynya that lies between Greenland and Canada in northern Baffin Bay. The world's largest Arctic polynya at about 85,000 km2 (33,000 sq mi), it creates a warm microclimate that provides a refuge for narwhal, beluga, walrus, and bowhead whales to feed and rest. While thin ice forms in some areas, the polynya is kept open by wind, tides and an ice bridge on its northern edge. Named the "North Water" by 19th century whalers who relied on it for spring passage, this polynya is one of the most biologically productive marine areas in the Arctic Ocean.
The Canadian Arctic Rift System is a major North American geological structure extending from the Labrador Sea in the southeast through Davis Strait, Baffin Bay and the Arctic Archipelago in the northwest. It consists of a series of interconnected rifts that formed during the Paleozoic, Mesozoic and Cenozoic eras. Extensional stresses along the entire length of the rift system have resulted in a variety of tectonic features, including grabens, half-grabens, basins and faults.
