Jarvis Island ( // ; formerly known as Bunker Island, or Bunker's Shoal) is an uninhabited 1 3⁄4-square-mile (4.5 km2) coral island located in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. It is an unincorporated, unorganized territory of the United States, administered by the United States Fish and Wildlife Service of the United States Department of the Interior as part of the National Wildlife Refuge system. Unlike most coral atolls, the lagoon on Jarvis is wholly dry.
A coral island is a type of island formed from coral detritus and associated organic material. They occur in tropical and sub-tropical areas, typically as part of coral reefs which have grown to cover a far larger area under the sea.
The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west and the Americas in the east.
Hawaii is the 50th and most recent state to have joined the United States, having received statehood on August 21, 1959. Hawaii is the only U.S. state located in Oceania, the only U.S. state located outside North America, and the only one composed entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean.
Jarvis is one of the Line Islands and for statistical purposes is also grouped as one of the United States Minor Outlying Islands.
The Line Islands, Teraina Islands or Equatorial Islands, is a chain of atolls and coral islands. Kingman Reef is largely submerged and Filippo Reef is shown on some maps, although its existence is doubted. The islands were formed by volcanic activity and are located in the central Pacific Ocean, south of the Hawaiian Islands. The 11 islands stretch for 2,350 kilometres in a northwest–southeast direction, making it one of the longest island chains of the world. Eight of the islands form part of Kiribati, while the remaining three are United States territories grouped with the United States Minor Outlying Islands. Only Kiritimati and Tabuaeran atolls and Teraina Island have a permanent population.
The United States Minor Outlying Islands are a statistical designation defined by the International Organization for Standardization's ISO 3166-1 code. The entry code is ISO 3166-2:UM. The minor outlying islands and groups of islands consist of eight United States insular areas in the Pacific Ocean and one in the Caribbean Sea.
While a few offshore anchorage spots are marked on maps, Jarvis island has no ports or harbors, and swift currents are a hazard. There is a boat landing area in the middle of the western shoreline near a crumbling day beacon, and another near the southwest corner of the island.The center of Jarvis island is a dried lagoon where deep guano deposits accumulated, which were mined for about 20 years during the nineteenth century. The island has a tropical desert climate, with high daytime temperatures, constant wind, and strong sun. Nights, however, are quite cool. The ground is mostly sandy and reaches 23 feet (7 meters) at its highest point. Because of the island's distance from other large landmasses, the Jarvis Island high point is the 36th most isolated peak in the world. The low-lying coral island has long been noted as hard to sight from small ships and is surrounded by a narrow fringing reef.
A day beacon is an unlighted nautical sea mark. A signboard attached to a day beacon is called a day mark and is used to identify it. Typically, day beacons mark channels whose key points are marked by lighted buoys. Day beacons may also mark smaller navigable routes in their entirety. They are the most common aid to nautical navigation in shallow water as they are relatively inexpensive to install and maintain. Navigation around day beacons is the same as with all other navigational aids.
A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.
Guano is the accumulated excrement of seabirds and bats. As a manure, guano is a highly effective fertilizer due to its exceptionally high content of nitrogen, phosphate and potassium: nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century guano trade played a pivotal role in the development of modern input-intensive farming, but its demand began to decline after the discovery of the Haber-Bosch process of nitrogen fixing led to the production of synthetic fertilizers. The demand for guano spurred the human colonization of remote bird islands in many parts of the world. During the 20th century, guano-producing birds became an important target of conservation programs and influenced the development of environmental consciousness. Today, guano is increasingly sought after by organic farmers.
Jarvis Island is one of two United States territories that are in the southern hemisphere (the other is American Samoa). Located only 25 miles (40 km) south of the equator, Jarvis has no known natural freshwater lens and scant rainfall. This creates a very bleak, flat landscape without any plants larger than shrubs. There is no evidence that the island has ever supported a self-sustaining human population. Its sparse bunch grass, prostrate vines and low-growing shrubs are primarily a nesting, roosting, and foraging habitat for seabirds, shorebirds, and marine wildlife.
American Samoa is an unincorporated territory of the United States located in the South Pacific Ocean, southeast of Samoa. Its location is centered on 14.2710° S, 170.1322° W. It is on the eastern border of the International Date Line, while independent Samoa is west of it.
An equator of a rotating spheroid is its zeroth circle of latitude (parallel). It is the imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles.
In hydrology, a lens, also called freshwater lens or Ghyben-Herzberg lens, is a convex-shaped layer of fresh groundwater that floats above the denser saltwater, usually found on small coral or limestone islands and atolls. This aquifer of fresh water is recharged through precipitation that infiltrates the top layer of soil and percolates downwards until it reaches the saturated zone. The recharge rate of the lens can be summarized by the following equation:
Jarvis Island is located in the Samoa Time Zone (UTC -11:00), the same time zone as American Samoa, Kingman Reef, Midway Atoll and Palmyra Atoll.
The Samoa Time Zone observes standard time by subtracting eleven hours from Coordinated Universal Time (UTC-11:00). The clock time in this zone is based on the mean solar time of the 165th meridian west of the Greenwich Observatory.
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
Kingman Reef is a largely submerged, uninhabited triangular-shaped reef, 9.5 nautical miles east-west and 5 nmi (9 km) north-south, located in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa at. It is the northernmost of the Northern Line Islands and lies 36 nautical miles (67 km) northwest of the next closest island, and 930 nautical miles (1,720 km) south of Honolulu.
The island's first known sighting by Europeans was on August 21, 1821, by the British ship Eliza Francis (or Eliza Frances) owned by Edward, Thomas and William Jarvisand commanded by Captain Brown. The island was visited by whaling vessels till the 1870s.
The United Kingdom of Great Britain and Ireland was a sovereign state established by the Acts of Union 1800, which merged the kingdoms of Great Britain and Ireland.
The US Exploring Expedition surveyed the island in 1841.In March 1857 the island was claimed for the United States under the Guano Islands Act and formally annexed on February 27, 1858.
The American Guano Company, which was incorporated in 1857, established claims in respect of Baker Island and Jarvis Island which was recognized under the U.S. Guano Islands Act of 1856.Beginning in 1858, several support structures were built on Jarvis Island, along with a two-story, eight-room "superintendent's house" featuring an observation cupola and wide verandahs. Tram tracks were laid down for bringing mined guano to the western shore. One of the first loads was taken by Samuel Gardner Wilder. For the following twenty-one years, Jarvis was commercially mined for guano, sent to the United States as fertilizer, but the island was abruptly abandoned in 1879, leaving behind about a dozen buildings and 8,000 tonnes of mined guano.
New Zealand entrepreneurs, including photographer Henry Winkelmann, then made unsuccessful attempts to continue guano extraction on Jarvis, and the two-story house was sporadically inhabited during the early 1880s. Squire Flockton was left alone on the island as caretaker for several months and committed suicide there in 1883, apparently from gin-fueled despair.His wooden grave marker was a carved plank which could be seen in the island's tiny four-grave cemetery for decades.
John T. Arundel & Co. resumed mining guano from 1886 to 1899.The United Kingdom annexed the island on June 3, 1889. Phosphate and copra entrepreneur John T. Arundel visited the island in 1909 on maiden voyage of the S.S. Ocean Queen and near the beach landing on the western shore members of the crew built a pyramidal day beacon made from slats of wood, which was painted white. The beacon was standing in 1935, and remained until at least 1942.
On August 30, 1913, the barquentine Amaranth (C. W. Nielson, captain) was carrying a cargo of coal from Newcastle, New South Wales, to San Francisco when it wrecked on Jarvis' southern shore. Ruins of ten wooden guano-mining buildings, the two-story house among them, could still be seen by the Amaranth crew, who left Jarvis aboard two lifeboats. One reached Pago Pago, American Samoa, and the other made Apia in Western Samoa. The ship's scattered remains were noted and scavenged for many years, and rounded fragments of coal from the Amaranth's hold were still being found on the south beach in the late 1930s.
Jarvis Island was reclaimed by the United States government and colonized from March 26, 1935, onwards, under the American Equatorial Islands Colonization Project (see also Howland Island and Baker Island). President Franklin D. Roosevelt assigned administration of the island to the U.S. Department of the Interior on May 13, 1936.Starting out as a cluster of large, open tents pitched next to the still-standing white wooden day beacon, the Millersville settlement on the island's western shore was named after a bureaucrat with the United States Department of Air Commerce. The settlement grew into a group of shacks built mostly with wreckage from the Amaranth (lumber from which was also used by the young Hawaiian colonists to build surfboards), but later, stone and wood dwellings were built and equipped with refrigeration, radio equipment, and a weather station. A crude aircraft landing area was cleared on the northeast side of the island, and a T-shaped marker which was intended to be seen from the air was made from gathered stones, but no airplane is known to have ever landed there.
At the beginning of World War II, an Imperial Japanese Navy submarine surfaced off the west coast of the Island. Believing that it was a U.S. Navy submarine which had come to fetch them, the four young colonists rushed down the steep western beach in front of Millersville towards the shore. The submarine answered their waves with fire from its deck gun, but no one was hurt in the attack. On February 7, 1942, the USCGC Taney evacuated the colonists, then shelled and burned the dwellings. The roughly cleared landing area on the island's northeast end was later shelled by the Japanese, leaving crater holes.
Jarvis was visited by scientists during the International Geophysical Year from July 1957 until November 1958. In January 1958 all scattered building ruins from both the nineteenth century guano diggings and the 1935–1942 colonization attempt were swept away without a trace by a severe storm which lasted several days and was witnessed by the scientists. When the IGY research project ended the island was abandoned again.By the early 1960s a few sheds, a century of accumulated trash, the scientists' house from the late 1950s and a solid, short lighthouse-like day beacon built two decades before were the only signs of human habitation on Jarvis.
On June 27, 1974, Secretary of the Interior Rogers Morton created Jarvis Island National Wildlife Refuge which was expanded in 2009 to add submerged lands within 12 nautical miles (22 km) of the island. The refuge now includes 1,273 acres (5.15 km2) of land and 428,580 acres (1,734.4 km2) of water. Along with six other islands, the island was administered by the U.S. Fish and Wildlife Service as part of the Pacific Remote Islands National Wildlife Refuge Complex. In January 2009, that entity was upgraded to the Pacific Remote Islands Marine National Monument by President George W. Bush.
A feral cat population, descendants of cats likely brought by colonists in the 1930s, wrought disruption to the island's wildlife and vegetation. These cats were removed through efforts which began in the mid-1960s and lasted until 1990 when they were completely eradicated.Nineteenth-century tram track remains can be seen in the dried lagoon bed at the island's center and the late 1930s-era lighthouse-shaped day beacon still stands on the western shore at the site of Millersville.
Public entry to any one including US citizenson Jarvis Island requires a special-use permit and is generally restricted to scientists and educators. The U.S. Fish and Wildlife Service and the United States Coast Guard periodically visit Jarvis.

Baker Island is an uninhabited atoll located just north of the equator in the central Pacific Ocean about 3,090 km (1,920 mi) southwest of Honolulu. The island lies almost halfway between Hawaii and Australia. Its nearest neighbor is Howland Island, 42 mi (68 km) to the north-northwest; both have been claimed as territories of the United States since 1857, though the United Kingdom considered them part of the British Empire between 1897 and 1936.
Howland Island is an uninhabited coral island located just north of the equator in the central Pacific Ocean, about 1,700 nautical miles (3,100 km) southwest of Honolulu. The island lies almost halfway between Hawaii and Australia and is an unincorporated, unorganized territory of the United States. Together with Baker Island it forms part of the Phoenix Islands. For statistical purposes, Howland is grouped as one of the United States Minor Outlying Islands. It covers 1,112 acres (4.50 km2), with 4 miles (6.4 km) of coastline. The island has an elongated banana-shape on a north–south axis.
Johnston Atoll, also known as Kalama Atoll to Native Hawaiians, is an unincorporated territory of the United States currently administered by the United States Fish and Wildlife Service. Johnston Atoll is a National Wildlife Refuge and is closed to public entry. Limited access for management needs is only by Letter of Authorization from the U.S. Air Force and Special Use Permit from the U.S. Fish and Wildlife Service.
Midway Atoll is a 2.4-square-mile (6.2 km2) atoll in the North Pacific Ocean at. Midway is roughly equidistant between North America and Asia. Midway Atoll is an unorganized, unincorporated territory of the United States. Midway continues to be the only island in the Hawaiian archipelago that is not part of the state of Hawaii. Unlike the other Hawaiian islands, Midway observes Samoa Time, which is one hour behind the time in the state of Hawaii. For statistical purposes, Midway is grouped as one of the United States Minor Outlying Islands. The Midway Atoll National Wildlife Refuge, encompassing 590,991.50 acres (239,165.77 ha) of land and water in the surrounding area, is administered by the United States Fish and Wildlife Service (FWS). The refuge and most of its surrounding area are part of the larger Papahānaumokuākea Marine National Monument.
Navassa Island is a small uninhabited island in the Caribbean Sea. Located northeast of Jamaica, south of Cuba, 40 nautical miles west of Jérémie on the south west peninsula of Haiti, the island is subject to an ongoing territorial dispute between Haiti and the United States, which officially administers it through the U.S. Fish and Wildlife Service. The U.S. has claimed the island since 1857, based on the Guano Islands Act of 1856. Haiti's claim over Navassa goes back to the Treaty of Ryswick in 1697 that established French possessions in mainland Hispaniola, that were transferred from Spain by the treaty. As well as the western half of the main island and certain other specifically named nearby islands, Haiti's 1801 constitution also claimed "other adjacent islands". Navassa was not one of the named islands. Since its 1874 Constitution, and after the establishment of the 1857 U.S. claim, Haiti has explicitly named "la Navase" as one of the territories it claims.
Palmyra Atoll is one of the Northern Line Islands, located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. The nearest continent is almost 3,355 miles to the northeast. The atoll is 4.6 sq mi (12 km2), and it is located in the equatorial Northern Pacific Ocean. Its 9 mi (14 km) of coastline has one anchorage known as West Lagoon.
An insular area of the United States is a U.S. territory that is neither a part of one of the 50 states nor of a Federal district. Article IV, Section 3, Clause 2 of the United States Constitution grants to United States Congress the responsibility of overseeing these territories, of which there are currently 14—three in the Caribbean Sea and 11 in the Pacific Ocean. These territories are classified by whether they are incorporated and whether they have an organized territorial government established by the U.S. Congress through an Organic Act. All territories but one are unincorporated, and all but four are considered to be unorganized. Five U.S. territories have a permanent, nonmilitary population. Each of them has a civilian government, a constitution, and enjoys some degree of local political autonomy.
Territories of the United States are sub-national administrative divisions overseen by the federal government. They differ from U.S. states and Native American tribes, which have limited sovereignty. The territories are classified by incorporation and whether they have an "organized" government through an organic act passed by Congress.
The Guano Islands Act is a United States federal law passed by the U.S. Congress that enables citizens of the United States to take possession, in the name of the United States, of unclaimed islands containing guano deposits. The islands can be located anywhere, so long as they are not occupied and not within the jurisdiction of another government. It also empowers the President of the United States to use the military to protect such interests and establishes the criminal jurisdiction of the United States in these territories.
Whenever any citizen of the United States discovers a deposit of guano on any island, rock, or key, not within the lawful jurisdiction of any other Government, and not occupied by the citizens of any other Government, and takes peaceable possession thereof, and occupies the same, such island, rock, or key may, at the discretion of the President, be considered as appertaining to the United States.
The French Frigate Shoals is the largest atoll in the Northwestern Hawaiian Islands. Its name commemorates French explorer Jean-François de La Pérouse, who nearly lost two frigates when attempting to navigate the shoals. It consists of a 20-mile (32 km) long crescent-shaped reef, twelve sandbars, and the 120-foot (37 m) high La Perouse Pinnacle, the only remnant of its volcanic origins. The total land area of the islets is 61.508 acres (24.891 ha). Total coral reef area of the shoals is over 232,000 acres (94,000 ha). Tern Island, with an area of 26.014 acres (10.527 ha), has a landing strip and permanent habitations for a small number of people. It is maintained as a field station in the Hawaiian Islands National Wildlife Refuge by the United States Fish and Wildlife Service. The French Frigate Shoals are about 487 nautical miles northwest of Honolulu.
Birnie Island is a small, uninhabited coral island, 20 hectares in area, part of the Phoenix Island group, that is part of the Republic of Kiribati. It is located about 100 km SE of Kanton Island and 90 km WNW of Rawaki Island, formerly known as Phoenix Island. It lies at. Birnie island measures only 1.2 km long and 0.5 km wide. There is no anchorage, but landing can be made on the lee beach.
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. The monument's marine areas are likely to also be incorporated in the Fagatele Bay National Marine Sanctuary.
The Pacific Remote Islands Marine National Monument is a group of unorganized, mostly unincorporated United States Pacific Island territories managed by the Fish and Wildlife Service of the United States Department of the Interior and the National Oceanic and Atmospheric Administration 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.
Howland and Baker islands are two uninhabited U.S. atolls in the Equatorial Pacific that are located close to one another. Both islands are wildlife refuges, the larger of which is Howland Island. The pair of islands may also be referred to as Baker and Howland Islands. They are both part of the larger political territory of the United States Minor Outlying Islands and they are also both part of the larger geographic grouping of the Phoenix Islands. Each is a National Wildlife Refuge managed by a division of Interior, the Fish and Wildlife Service. On January 6, 2009, President George Bush, in creating the monument, added both islands to the Pacific Remote Islands Marine National Monument.
Amaranth was a four-masted barquentine built by Matthew Turner of Benicia, California in 1901. Amaranth sailed in the China trade between Puget Sound and Shanghai. She was wrecked on a guano island in the South Pacific in 1913 while carrying a load of coal.
Under a Jarvis Moon is a 2010 documentary film about the young men, mostly of Hawaiian origin, sent in the 1930s and 1940s to colonize the Line Island of Jarvis and the Phoenix Islands of Howland and Baker. Directed by Noelle Kahanu and Heather Giugni, the film is related to a 2002 Bishop Museum exhibition "Hui Panala'au: Hawaiian Colonists, American Citizens."
The American Equatorial Islands Colonization Project was a plan initiated in 1935 by the U.S. Department of Commerce to place citizens of the United States on uninhabited Howland, Baker and Jarvis islands in the central Pacific Ocean so that weather stations and landing fields could be built for military and commercial use on air routes between Australia and California. Additionally, the U.S. government wanted to claim these remote islands to provide a check on eastern territorial expansion by the Empire of Japan. The colonists, who became known as Hui Panala'au, were primarily young native Hawaiian men and other male students recruited from schools in Hawaii. In 1937, the project was expanded to include Canton and Enderbury in the Phoenix Islands. The project ended in early 1942 when the colonists were rescued from the islands at the start of the War in the Pacific.
