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. | Established as a territory of the UK in 1965, a number of the British Indian Ocean Territory (BIOT) islands were transferred to the Seychelles when it attained independence in 1976. Subsequently, BIOT has consisted only of the six main island groups comprising the Chagos Archipelago. The largest and most southerly of the islands, Diego Garcia, contains a joint UK-US naval support facility. All of the remaining islands are uninhabited. Former agricultural workers, earlier residents in the islands, were relocated primarily to Mauritius but also to the Seychelles, between 1967 and 1973. In 2000, a British High Court ruling invalidated the local immigration order that had excluded them from the archipelago, but upheld the special military status of Diego Garcia. |

Disputes - international | some maritime disputes (see littoral states) | Mauritius and Seychelles claim the Chagos Archipelago and its former inhabitants, who reside chiefly in Mauritius, but in 2001 were granted UK citizenship and the right to repatriation since eviction in 1965; the UK resists the Chagossians' demand for an immediate return to the islands; repatriation is complicated by the exclusive US military lease of Diego Garcia that restricted access to the largest island in the chain |
Economy - overview | Economic activity is limited to the exploitation of natural resources, including petroleum, natural gas, fish, and seals. | All economic activity is concentrated on the largest island of Diego Garcia, where joint UK-US defense facilities are located. Construction projects and various services needed to support the military installations are done by military and contract employees from the UK, Mauritius, the Philippines, and the US. There are no industrial or agricultural activities on the islands. When the Ilois return, they plan to reestablish sugarcane production and fishing. |

note: approximately 1,200 former agricultural workers resident in the Chagos Archipelago, often referred to as Chagossians or Ilois, were relocated to Mauritius and the Seychelles in the 1960s and 1970s, in November 2000 they were granted the right of return by a British High Court ruling, though no timetable has been set; in 2001, there were approximately 1,500 UK and US military personnel and 2,000 civilian contractors living on the island of Diego Garcia (July 2004 est.) |

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) | flat and low (most areas do not exceed four meters in elevation) |
