Airports	1 (2003 est.)	-
Airports - with unpaved runways	total: 1 1,524 to 2,437 m: 1 (2004 est.)	-
Area	total: 373 sq km land: 373 sq km water: 0 sq km	total: 20.327 million sq km note: includes Amundsen Sea, Bellingshausen Sea, part of the Drake Passage, Ross Sea, a small part of the Scotia Sea, Weddell Sea, and other tributary water bodies

Background	This desolate, mountainous island was named after a Dutch whaling captain who indisputably discovered it in 1614 (earlier claims are inconclusive). Visited only occasionally by seal hunters and trappers over the following centuries, the island came under Norwegian sovereignty in 1929. The long dormant Haakon VII Toppen/Beerenberg volcano resumed activity in 1970; it is the northernmost active volcano on earth.	A decision by the International Hydrographic Organization in the spring of 2000 delimited a fifth world ocean - the Southern Ocean - from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude, which coincides with the Antarctic Treaty Limit. The Southern Ocean is now the fourth largest of the world's five oceans (after the Pacific Ocean, Atlantic Ocean, and Indian Ocean, but larger than the Arctic Ocean).
Climate	arctic maritime with frequent storms and persistent fog	sea temperatures vary from about 10 degrees Celsius to -2 degrees Celsius; cyclonic storms travel eastward around the continent and frequently are intense because of the temperature contrast between ice and open ocean; the ocean area from about latitude 40 south to the Antarctic Circle has the strongest average winds found anywhere on Earth; in winter the ocean freezes outward to 65 degrees south latitude in the Pacific sector and 55 degrees south latitude in the Atlantic sector, lowering surface temperatures well below 0 degrees Celsius; at some coastal points intense persistent drainage winds from the interior keep the shoreline ice-free throughout the winter
Coastline	124.1 km	17,968 km
Country name	conventional long form: none conventional short form: Jan Mayen	-
Dependency status	territory of Norway; since August 1994, administered from Oslo through the county governor (fylkesmann) of Nordland; however, authority has been delegated to a station commander of the Norwegian Defense Communication Service	-
Disputes - international	none	Antarctic Treaty defers claims (see Antarctica entry), but Argentina, Australia, Chile, France, NZ, Norway, and UK assert claims (some overlapping), including the continental shelf in the Southern Ocean; several states have expressed an interest in extending those continental shelf claims under the United Nations Convention on the Law of the Sea (LOS) to include undersea ridges; the US and most other states do not recognize the land or maritime claims of other states and have made no claims themselves (the US and Russia have reserved the right to do so); no formal claims have been made in the sector between 90 degrees west and 150 degrees west
Economy - overview	Jan Mayen is a volcanic island with no exploitable natural resources. Economic activity is limited to providing services for employees of Norway's radio and meteorological stations on the island.	Fisheries in 2000-01 (1 July to 30 June) landed 112,934 metric tons, of which 87% was krill and 11% Patagonian toothfish. International agreements were adopted in late 1999 to reduce illegal, unreported, and unregulated fishing, which in the 2000-01 season landed, by one estimate, 8,376 metric tons of Patagonian and antarctic toothfish. In the 2000-01 antarctic summer 12,248 tourists, most of them seaborne, visited the Southern Ocean and Antarctica, compared to 14,762 the previous year.
Elevation extremes	lowest point: Norwegian Sea 0 m highest point: Haakon VII Toppen/Beerenberg 2,277 m	lowest point: -7,235 m at the southern end of the South Sandwich Trench highest point: sea level 0 m
Environment - current issues	NA	increased solar ultraviolet radiation resulting from the Antarctic ozone hole in recent years, reducing marine primary productivity (phytoplankton) by as much as 15% and damaging the DNA of some fish; illegal, unreported, and unregulated fishing in recent years, especially the landing of an estimated five to six times more Patagonian toothfish than the regulated fishery, which is likely to affect the sustainability of the stock; large amount of incidental mortality of seabirds resulting from long-line fishing for toothfish note: the now-protected fur seal population is making a strong comeback after severe overexploitation in the 18th and 19th centuries
Environment - international agreements	-	the Southern Ocean is subject to all international agreements regarding the world's oceans; in addition, it is subject to these agreements specific to the Antarctic region: International Whaling Commission (prohibits commercial whaling south of 40 degrees south [south of 60 degrees south between 50 degrees and 130 degrees west]); Convention on the Conservation of Antarctic Seals (limits sealing); Convention on the Conservation of Antarctic Marine Living Resources (regulates fishing) note: many nations (including the US) prohibit mineral resource exploration and exploitation south of the fluctuating Polar Front (Antarctic Convergence) which is in the middle of the Antarctic Circumpolar Current and serves as the dividing line between the very cold polar surface waters to the south and the warmer waters to the north
Flag description	the flag of Norway is used	-
Geographic coordinates	71 00 N, 8 00 W	65 00 S, 0 00 E (nominally), but the Southern Ocean has the unique distinction of being a large circumpolar body of water totally encircling the continent of Antarctica; this ring of water lies between 60 degrees south latitude and the coast of Antarctica, and encompasses 360 degrees of longitude
Geography - note	barren volcanic island with some moss and grass	the major chokepoint is the Drake Passage between South America and Antarctica; the Polar Front (Antarctic Convergence) is the best natural definition of the northern extent of the Southern Ocean; it is a distinct region at the middle of the Antarctic Circumpolar Current that separates the very cold polar surface waters to the south from the warmer waters to the north; the Front and the Current extend entirely around Antarctica, reaching south of 60 degrees south near New Zealand and near 48 degrees south in the far South Atlantic coinciding with the path of the maximum westerly winds
Irrigated land	0 sq km (1998 est.)	-
Land boundaries	0 km	-
Land use	arable land: 0% permanent crops: 0% other: 100% (2001)	-
Legal system	the laws of Norway, where applicable, apply	-
Location	Northern Europe, island between the Greenland Sea and the Norwegian Sea, northeast of Iceland	body of water between 60 degrees south latitude and Antarctica
Map references	Arctic Region	Antarctic Region
Maritime claims	territorial sea: 4 nm contiguous zone: 10 nm exclusive economic zone: 200 nm continental shelf: 200-m depth or to the depth of exploitation	-
Military - note	defense is the responsibility of Norway	-
Natural hazards	dominated by the volcano Haakon VII Toppen/Beerenberg; volcanic activity resumed in 1970	huge icebergs with drafts up to several hundred meters; smaller bergs and iceberg fragments; sea ice (generally 0.5 to 1 meter thick) with sometimes dynamic short-term variations and with large annual and interannual variations; deep continental shelf floored by glacial deposits varying widely over short distances; high winds and large waves much of the year; ship icing, especially May-October; most of region is remote from sources of search and rescue
Natural resources	none	probable large and possible giant oil and gas fields on the continental margin, manganese nodules, possible placer deposits, sand and gravel, fresh water as icebergs, squid, whales, and seals - none exploited; krill, fishes
Population	no indigenous inhabitants note: personnel operate the Long Range Navigation (Loran-C) base and the weather and coastal services radio station (July 2004 est.)	-
Ports and harbors	none; offshore anchorage only	McMurdo, Palmer, and offshore anchorages in Antarctica note: few ports or harbors exist on the southern side of the Southern Ocean; ice conditions limit use of most of them to short periods in midsummer; even then some cannot be entered without icebreaker escort; most antarctic ports are operated by government research stations and, except in an emergency, are not open to commercial or private vessels; vessels in any port south of 60 degrees south are subject to inspection by Antarctic Treaty observers (see Article 7)
Radio broadcast stations	AM NA, FM NA, shortwave NA note: there is one radio and meteorological station (1998)	-
Terrain	volcanic island, partly covered by glaciers	the Southern Ocean is deep, 4,000 to 5,000 meters over most of its extent with only limited areas of shallow water; the Antarctic continental shelf is generally narrow and unusually deep - its edge lying at depths of 400 to 800 meters (the global mean is 133 meters); the Antarctic icepack grows from an average minimum of 2.6 million square kilometers in March to about 18.8 million square kilometers in September, better than a sixfold increase in area; the Antarctic Circumpolar Current (21,000 km in length) moves perpetually eastward; it is the world's largest ocean current, transporting 130 million cubic meters of water per second - 100 times the flow of all the world's rivers
Transportation - note	-	Drake Passage offers alternative to transit through the Panama Canal
