Background | The following US Pacific island territories constitute the Pacific Remote Islands National Wildlife Refuge Complex and as such are managed by the Fish and Wildlife Service of the US Department of Interior. These remote refuges are the most widespread collection of marine- and terrestrial-life protected areas on the planet under a single country's jurisdiction. They protect many endemic species including corals, fish, shellfish, marine mammals, seabirds, water birds, land birds, insects, and vegetation not found elsewhere.
Baker Island: 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 began on this island but was disrupted by World War II and thereafter abandoned. The island was established as a National Wildlife Refuge in 1974. Howland Island: Discovered by the US early in the 19th century, the island was officially claimed by the US in 1857. Both US and British companies mined for guano until about 1890. In 1935, a short-lived attempt at colonization began on this island, similar to the effort on nearby Baker Island, but was disrupted by World War II and thereafter abandoned. The famed American aviatrix Amelia EARHART disappeared while seeking out Howland Island as a refueling stop during her 1937 round-the-world flight; Earhart Light, a day beacon near the middle of the west coast, was named in her memory. The island was established as a National Wildlife Refuge in 1974. Jarvis Island: First discovered by the British in 1821, the uninhabited island was annexed by the US in 1858, but abandoned in 1879 after tons of guano had been removed. The UK annexed the island in 1889, but never carried out plans for further exploitation. The US occupied and reclaimed the island in 1935 until it was abandoned in 1942 during World War II. The island was established as a National Wildlife Refuge in 1974. Johnston Atoll: Both the US and the Kingdom of Hawaii annexed Johnston Atoll in 1858, but it was the US that mined the guano deposits until the late 1880s. Johnston and Sand Islands were designated wildlife refuges in 1926. The US Navy took over the atoll in 1934, and subsequently the US Air Force assumed control in 1948. The site was used for high-altitude nuclear tests in the 1950s and 1960s, and until late in 2000 the atoll was maintained as a storage and disposal site for chemical weapons. Munitions destruction is now complete. Cleanup and closure of the facility was completed by May 2005. The Fish and Wildlife Service and the US Air Force are currently discussing future management options; in the interim, Johnston Atoll and the three-mile Naval Defensive Sea around it remain under the jurisdiction and administrative control of the US Air Force. Kingman Reef: The US annexed the reef in 1922. Its sheltered lagoon served as a way station for flying boats on Hawaii-to-American Samoa flights during the late 1930s. There are no terrestrial plants on the reef, which is frequently awash, but it does support abundant and diverse marine fauna and flora. In 2001, the waters surrounding the reef out to 12 nm were designated a US National Wildlife Refuge. Midway Islands: The US took formal possession of the islands in 1867. The laying of the trans-Pacific cable, which passed through the islands, brought the first residents in 1903. Between 1935 and 1947, Midway was used as a refueling stop for trans-Pacific flights. The US naval victory over a Japanese fleet off Midway in 1942 was one of the turning points of World War II. The islands continued to serve as a naval station until closed in 1993. Today the islands are a National Wildlife Refuge and are the site of the world's largest Laysan albatross colony. Palmyra Atoll: The Kingdom of Hawaii claimed the atoll in 1862, and the US included it among the Hawaiian Islands when it annexed the archipelago in 1898. The Hawaii Statehood Act of 1959 did not include Palmyra Atoll, which is now partly privately owned by the Nature Conservancy with the rest owned by the Federal government and managed by the US Fish and Wildlife Service. These organizations are managing the atoll as a wildlife refuge. The lagoons and surrounding waters within the 12 nm US territorial seas were transferred to the US Fish and Wildlife Service and designated as a National Wildlife Refuge in January 2001. |
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 | Baker, Howland, and Jarvis Islands: equatorial; scant rainfall, constant wind, burning sun
Johnston Atoll and Kingman Reef: tropical, but generally dry; consistent northeast trade winds with little seasonal temperature variation Midway Islands: subtropical with cool, moist winters (December to February) and warm, dry summers (May to October); moderated by prevailing easterly winds; most of the 1,067 mm (42 in) of annual rainfall occurs during the winter Palmyra Atoll: equatorial, hot; located within the low pressure area of the Intertropical Convergence Zone (ITCZ) where the northeast and southeast trade winds meet, it is extremely wet with between 4,000-5,000 mm (160-200 in) of rainfall each year |
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 |

Dependency status | unincorporated territories 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
note on Palmyra Atoll: incorporated Territory of the US; partly privately owned and partly federally owned; administered from Washington, DC, by the Fish and Wildlife Service of the US Department of the Interior; the Office of Insular Affairs of the US Department of the Interior continues to administer nine excluded areas comprising certain tidal and submerged lands within the 12 nm territorial sea or within the lagoon |
- |
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 | no economic activity | 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. |

Environment - current issues | Baker, Howland, and Jarvis Islands, and Johnston Atoll: no natural fresh water resources
Kingman Reef: none Midway Islands and Palmyra Atoll: 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 |

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 | Baker, Howland, and Jarvis Islands: scattered vegetation consisting of grasses, prostrate vines, and low growing shrubs; primarily a nesting, roosting, and foraging habitat for seabirds, shorebirds, and marine wildlife
Johnston Atoll: Johnston Island and Sand Island are natural islands, which have been expanded by coral dredging; North Island (Akau) and East Island (Hikina) are manmade islands formed from coral dredging; the egg-shaped reef is 34 km in circumference Kingman Reef: barren coral atoll with deep interior lagoon; closed to the public Midway Islands: a coral atoll managed as a national wildlife refuge and open to the public for wildlife-related recreation in the form of wildlife observation and photography Palmyra Atoll: the high rainfall and resulting lush vegetation make the environment of this atoll unique among the US Pacific Island territories; it supports one of the largest remaining undisturbed stands of Pisonia beach forest in the Pacific |
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 |

Natural hazards | Baker, Howland, and Jarvis Islands: the narrow fringing reef surrounding the island can be a maritime hazard
Kingman Reef: wet or awash most of the time, maximum elevation of less than 1 m makes Kingman Reef a maritime hazard Midway Islands, Johnston, and Palmyra Atolls: NA |
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 | terrestrial and aquatic wildlife | 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: public entry is by special-use permit from US Fish and Wildlife Service only and generally restricted to scientists and educators; visited annually by US Fish and Wildlife Service Johnston Atoll: in previous years, an average of 1,100 US military and civilian contractor personnel were present; as of May 2005 all US government personnel had left the island Midway Islands: approximately 40 people make up the staff of US Fish and Wildlife Service and their services contractor living at the atoll Palmyra Atoll: four to 20 Nature Conservancy and US Fish and Wildlife staff |

Ports and harbors | - | 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) |
Terrain | low and nearly level sandy coral islands with narrow fringing reefs that have developed at the top of submerged volcanic mountains, which in most cases rise steeply from the ocean floor | 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 |
