Question: The Coppermine River is a river in the North Slave and Kitikmeot regions of the Northwest Territories and Nunavut in Canada, it  flows generally north to Coronation Gulf, an arm of which ocean that is the smallest and shallowest of the world's five major oceans?
Context: Asiagmiut (also Aziagmut) were an Arctic coast Copper Inuit group in Kitikmeot Region, Nunavut, Canada.  They were located near Ogden Bay east of the Coppermine River, between the Coppermine River and Tree rivers, west of Kent Peninsula, east of Kent Peninsula, and opposite Melbourne Island.  Hudson (1989) mentions the Asiagmiut, a Caribou Inuit group of the Kazan River area, who were subsistence hunters. The Napaaktoktok River is a waterway in the Kitikmeot region of Nunavut in Canada.  It flows generally north to Coronation Gulf, an arm of the Arctic Ocean.  The Napaaktoktok runs parallel to the Coppermine River, 14.4 km to the west, and the Asiak River, 15.2 km to the east. The Croker River is a waterway above the Arctic Circle on the mainland of Northern Canada in the western Kitikmeot Region, Nunavut.  It is the largest river between Darnley Bay (in the Northwest Territories) and Coronation Gulf that flows into Amundsen Gulf.  The Croker averages 180 ft in width. Akaitcho (variants: Akaicho or Ekeicho; translation: "Big-Foot" or "Big-Feet"; meaning: "like a wolf with big paws, he can travel long distances over snow") (ca. 1786-1838) was a Copper Indian, and Chief of the Yellowknives.  His territory included the region from the eastern portion of the Great Slave Lake, in the Northwest Territories, Canada, to the Coppermine River, in Nunavut.  He was recruited to act as interpreter, guide, and hunter for John Franklin's first of three Arctic expeditions, the Coppermine Expedition of 1819–1822. The Arctic Ocean is the smallest and shallowest of the world's five major oceans.  The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean.  Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean. Kugluktuk (Inuinnaqtun: "Qurluktuk", "the place of moving water"; Inuktitut: ᖁᕐᓗᖅᑐᖅ ] , formerly Coppermine until 1 January 1996) is a hamlet located at the mouth of the Coppermine River in the Kitikmeot Region of Nunavut, Canada, on Coronation Gulf, southwest of Victoria Island.  It is the westernmost community in Nunavut, near the border with the Northwest Territories. The Central Arctic was an electoral district of the Northwest Territories, Canada, created in 1966 and abolished in 1983.  The district consisted of Pelly Bay, Spence Bay, Gjoa Haven, Cambridge Bay, Bathurst Inlet, Bay Chimo, Coppermine and Holman.  For the 1983 election, Holman was moved to the Nunakput district and the others split between Kitikmeot West and Kitikmeot East.  Today Holman, now Ulukhaktok, is the only one of the communities in the Northwest Territories as after division the others became part of Nunavut. The Asiak River is a waterway in the Kitikmeot Region of Nunavut in Canada.  It flows generally north to Coronation Gulf, an arm of the Arctic Ocean.  It runs parallel to the Coppermine River, 29 km to the west. The Coppermine River is a river in the North Slave and Kitikmeot regions of the Northwest Territories and Nunavut in Canada.  It is 845 km long.  It rises in Lac de Gras, a small lake near Great Slave Lake and flows generally north to Coronation Gulf, an arm of the Arctic Ocean.  The river freezes in winter but may still flow under the ice. The Back River (Dogrib: Thlewechodyeth, Inuktitut: Haningayok, or Great Fish River), is a river in the Northwest Territories and Nunavut in Canada.  It rises at an unnamed lake in the North Slave Region of the Northwest Territories and flows more than 974 km mostly through Kivalliq Region, Nunavut, to its mouth at the Arctic Ocean in the Kitikmeot Region of Nunavut.
