Background | The Arctic Ocean is the smallest of the world's five oceans (after the Pacific Ocean, Atlantic Ocean, Indian Ocean, and the recently delimited Southern Ocean). The Northwest Passage (US and Canada) and Northern Sea Route (Norway and Russia) are two important seasonal waterways. A sparse network of air, ocean, river, and land routes circumscribes the Arctic Ocean. | The US took possession of the island in 1857, and its guano deposits were mined by US and British companies during the second half of the 19th century. In 1935, a short-lived attempt at colonization was begun on this island - as well as on nearby Howland Island - but was disrupted by World War II and thereafter abandoned. Presently the island is a National Wildlife Refuge run by the US Department of the Interior; a day beacon is situated near the middle of the west coast. |
Climate | polar climate characterized by persistent cold and relatively narrow annual temperature ranges; winters characterized by continuous darkness, cold and stable weather conditions, and clear skies; summers characterized by continuous daylight, damp and foggy weather, and weak cyclones with rain or snow | equatorial; scant rainfall, constant wind, burning sun |

Country name | - | conventional long form: none
conventional short form: Baker Island |
Dependency status | - | unincorporated territory of the US; administered from Washington, DC, by the Fish and Wildlife Service of the US Department of the Interior as part of the National Wildlife Refuge system |
Disputes - international | some maritime disputes (see littoral states) | none |
Economy - overview | Economic activity is limited to the exploitation of natural resources, including petroleum, natural gas, fish, and seals. | no economic activity |
Elevation extremes | lowest point:
Fram Basin -4,665 m highest point: sea level 0 m |
lowest point: Pacific Ocean 0 m
highest point: unnamed location 8 m |
Environment - current issues | endangered marine species include walruses and whales; fragile ecosystem slow to change and slow to recover from disruptions or damage; thinning polar icepack | no natural fresh water resources |
Flag description | - | the flag of the US is used |
Geographic coordinates | 90 00 N, 0 00 E | 0 13 N, 176 31 W |
Geography - note | major chokepoint is the southern Chukchi Sea (northern access to the Pacific Ocean via the Bering Strait); strategic location between North America and Russia; shortest marine link between the extremes of eastern and western Russia; floating research stations operated by the US and Russia; maximum snow cover in March or April about 20 to 50 centimeters over the frozen ocean; snow cover lasts about 10 months | treeless, sparse, and scattered vegetation consisting of grasses, prostrate vines, and low growing shrubs; primarily a nesting, roosting, and foraging habitat for seabirds, shorebirds, and marine wildlife |

Location | body of water between Europe, Asia, and North America, mostly north of the Arctic Circle | Oceania, atoll in the North Pacific Ocean, about half way between Hawaii and Australia |

Maritime claims | - | territorial sea: 12 nm
exclusive economic zone: 200 nm |
Military - note | - | defense is the responsibility of the US; visited annually by the US Coast Guard |
Natural hazards | ice islands occasionally break away from northern Ellesmere Island; icebergs calved from glaciers in western Greenland and extreme northeastern Canada; permafrost in islands; virtually ice locked from October to June; ships subject to superstructure icing from October to May | the narrow fringing reef surrounding the island can be a maritime hazard |
Natural resources | sand and gravel aggregates, placer deposits, polymetallic nodules, oil and gas fields, fish, marine mammals (seals and whales) | guano (deposits worked until 1891), terrestrial and aquatic wildlife |
Population | - | uninhabited
note: American civilians evacuated in 1942 after Japanese air and naval attacks during World War II; occupied by US military during World War II, but abandoned after the war; public entry is by special-use permit from US Fish and Wildlife Service only and generally restricted to scientists and educators; a cemetery and remnants of structures from early settlement are located near the middle of the west coast; visited annually by US Fish and Wildlife Service (2004 est.) |
Ports and harbors | Churchill (Canada), Murmansk (Russia), Prudhoe Bay (US) | none; offshore anchorage only; note - there is one small boat landing area along the middle of the west coast |
Terrain | central surface covered by a perennial drifting polar icepack that averages about 3 meters in thickness, although pressure ridges may be three times that size; clockwise drift pattern in the Beaufort Gyral Stream, but nearly straight-line movement from the New Siberian Islands (Russia) to Denmark Strait (between Greenland and Iceland); the icepack is surrounded by open seas during the summer, but more than doubles in size during the winter and extends to the encircling landmasses; the ocean floor is about 50% continental shelf (highest percentage of any ocean) with the remainder a central basin interrupted by three submarine ridges (Alpha Cordillera, Nansen Cordillera, and Lomonosov Ridge) | low, nearly level coral island surrounded by a narrow fringing reef |
Transportation - note | - | there is a day beacon near the middle of the west coast |
