Kingman Reef is a largely submerged, uninhabited, triangle-shaped reef, geologically an atoll, 9.0 nmi (20 km) east-west and 4.5 nmi (8 km) north-south, in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa. It has an area of 3 hectares and is a unincorporated territory of the United States in Oceania. The reef is administered by the United States Fish and Wildlife Service as the Kingman Reef National Wildlife Refuge. It was claimed by the US in 1859, and later used briefly as stopover for commercial Pacific flying boat routes in the 1930s going to New Zealand; however, the route was changed with a different stopover. It was administered by the Navy from 1934 to 2000, and thereafter the Fish and Wildlife service. It has since become a marine protected area. In the 19th century it was noted as maritime hazard, earning the name Hazard Rocks, and is known to have been hit once in 1876. In the 21st century it has been noted for is marine biodiversity and remote nature. There are hundreds of species of fish and coral on and around the reef.
The Marshall Islands consist of two archipelagic island chains of 30 atolls and 1,152 islands, which form two parallel groups—the "Ratak" (sunrise) chain and the "Ralik" (sunset) chain. The Marshalls are located in the North Pacific Ocean and share maritime boundaries with Micronesia and Kiribati. Two-thirds of the nation's population lives in the capital of Majuro and the settlement of Ebeye. The outer islands are sparsely populated due to lack of employment opportunities and economic development.
The Samoan archipelago is a chain of 16 islands and numerous seamounts covering 3,123 km2 (1,206 sq mi) in the central South Pacific, south of the equator, about halfway between Hawaii and New Zealand, forming part of Polynesia and of the wider region of Oceania. The islands are Savaiʻi, Upolu, Tutuila, ’Uvea, Taʻū, Ofu, Olosega, Apolima, Manono, Nuʻutele, Niulakita, Nuʻulua, Namua, Fanuatapu, Rose Atoll, Nu'ulopa, as well as the submerged Vailuluʻu, Pasco banks, and Alexa Bank.
Tokelau is a dependent territory of New Zealand in the southern Pacific Ocean. It consists of three tropical coral atolls: Atafu, Nukunonu, and Fakaofo. They have a combined land area of 10 km2 (4 sq mi). In addition to these three, Swains Island, which forms part of the same archipelago, is the subject of an ongoing territorial dispute; it is currently administered by the United States as part of American Samoa. Tokelau lies north of the Samoan Islands, east of Tuvalu, south of the Phoenix Islands, southwest of the more distant Line Islands, and northwest of the Cook Islands.
The Hawaiian Islands are an archipelago of eight major volcanic islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some 1,500 miles from the island of Hawaiʻi in the south to northernmost Kure Atoll. Formerly called the Sandwich Islands, the present name for the archipelago is derived from the name of its largest island, Hawaiʻi.
Kure Atoll or Ocean Island is an atoll in the Pacific Ocean 48 nautical miles west-northwest of Midway Atoll in the Northwestern Hawaiian Islands at 28°25′N178°20′W. A coral ring 10 km across encloses a lagoon several meters deep. The only land of significant size is called Green Island and is a habitat for hundreds of thousands of seabirds. A short, unused and unmaintained runway and a portion of one building, both from a former United States Coast Guard LORAN station, are located on the island. Politically, it is part of Hawaii, although separated from the rest of the state by Midway, which is a separate unorganized territory. Green Island, in addition to being the nesting grounds for tens of thousands of seabirds, has recorded several vagrant terrestrial birds, including snow bunting, eyebrowed thrush, brambling, olive-backed pipit, black kite, Steller's sea eagle and Chinese sparrowhawk. It is currently managed as a Wildlife Bird Sanctuary by the State of Hawaii's Department of Land and Natural Resource–Division of Forestry and Wildlife as one of the co-trustees of Papahānaumokuākea Marine National Monument with support from the Kure Atoll Conservancy.
In the law of the United States, an insular area is a U.S.-associated jurisdiction that is not part of a U.S. state or the District of Columbia. This includes fourteen U.S. territories administered under U.S. sovereignty, as well as three sovereign states each with a Compact of Free Association with the United States. The term also may be used to refer to the previous status of the Swan Islands, Hawaii, Puerto Rico, and the Philippines, as well as the Trust Territory of the Pacific Islands when it existed.
Territories of the United States are sub-national administrative divisions overseen by the federal government of the United States. The various American territories differ from the U.S. states and Indian reservations as they are not sovereign entities. In contrast, each state has a sovereignty separate from that of the federal government and each federally recognized Native American tribe possesses limited tribal sovereignty as a "dependent sovereign nation." Territories are classified by incorporation and whether they have an "organized" government through an organic act passed by the Congress. American territories are under American sovereignty and, consequently, may be treated as part of the United States proper in some ways and not others. Unincorporated territories in particular are not considered to be integral parts of the United States, and the Constitution of the United States applies only partially in those territories.
The Samoan Islands are an archipelago covering 3,030 km2 (1,170 sq mi) in the central South Pacific, forming part of Polynesia and of the wider region of Oceania. Administratively, the archipelago comprises all of the Independent State of Samoa and most of American Samoa. The land masses of the two Samoan jurisdictions are separated by 64 km (40 mi) of ocean at their closest points.
Ebeye is the most populous island of Kwajalein Atoll in the Marshall Islands, as well as the center for Marshallese culture in the Ralik Chain of the archipelago. Settled on 80 acres of land, it has a population of more than 15,000. Over 50% of the population is estimated to be under the age of 18.
Caroline Island is the easternmost of several uninhabited coral atolls comprising the southern Line Islands in the central Pacific Ocean nation of Kiribati.
Rose Atoll, sometimes called Rose Island or Motu O Manu by people of the Manu'a Islands, is an oceanic atoll within the U.S. territory of American Samoa. An uninhabited wildlife refuge, it is the southernmost point belonging to the United States. The land area is just 0.05 km2 at high tide. The total area of the atoll, including lagoon and reef flat amounts to 6.33 km2. Just west of the northernmost point is a channel into the lagoon, about 80 m wide. There are two islets on the northeastern rim of the reef, larger Rose Island in the east and the non-vegetated Sand Island in the north. The Rose Atoll Marine National Monument that lies on the two outstanding islands of the Atoll is managed cooperatively between the U.S. Fish and Wildlife Service and the government of American Samoa.
Rose Atoll Marine National Monument is a United States National Monument in the South Pacific Ocean, covering 8,571,633 acres and encompassing the Rose Atoll National Wildlife Refuge, which was established in 1973 with 39,066 acres, only 20 acres (8.1 ha) of which is emergent. The monument's marine areas are likely to also be incorporated in the National Marine Sanctuary of American Samoa.
The Pacific Remote Islands Marine National Monument is a group of unorganized, mostly unincorporated United States Pacific Island territories managed by the United States Fish and Wildlife Service of the United States Department of the Interior and the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce. 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.
The following outline is provided as an overview of and topical guide to American Samoa:
American Samoa is an unincorporated territory of the United States located in the South Pacific Ocean, southeast of the island country of Samoa. Centered on 14.3°S 170.7°W, it is east of the International Date Line and the Wallis and Futuna Islands, west of the Cook Islands, north of Tonga, and some 500 kilometers (310 mi) south of Tokelau. American Samoa is the southernmost territory of the United States and one of two U.S. territories south of the Equator, along with the uninhabited Jarvis Island.
The Macdonald hotspot is a volcanic hotspot in the southern Pacific Ocean. The hotspot was responsible for the formation of the Macdonald Seamount, and possibly the Austral-Cook Islands chain. It probably did not generate all of the volcanism in the Austral and Cook Islands as age data imply that several additional hotspots were needed to generate some volcanoes.
Wōdejebato is a Cretaceous guyot or tablemount in the northern Marshall Islands, Pacific Ocean. Wōdejebato is probably a shield volcano and is connected through a submarine ridge to the smaller Pikinni Atoll 74 kilometres (46 mi) southeast of the guyot; unlike Wōdejebato, Pikinni rises above sea level. The seamount rises for 4,420 metres (14,500 ft) to 1,335 metres (4,380 ft) depth and is formed by basaltic rocks. The name Wōdejebato refers to a sea god of Pikinni.
Limalok is a Cretaceous-Paleocene guyot/tablemount in the southeastern Marshall Islands, one of a number of seamounts in the Pacific Ocean. It was probably formed by a volcanic hotspot in present-day French Polynesia. Limalok lies southeast of Mili Atoll and Knox Atoll, which rise above sea level, and is joined to each of them through a volcanic ridge. It is located at a depth of 1,255 metres (4,117 ft) and has a summit platform with an area of 636 square kilometres (246 sq mi).
