Midway Atoll (play /ˈmɪdw/; also called Midway Island and Midway Islands; Hawaiian: Pihemanu Kauihelani) is a 2.4-square-mile (6.2-km²) atoll in the North Pacific Ocean, near the northwestern end of the Hawaiian archipelago, about a third of the way between Honolulu, Hawaii, and Tokyo, Japan. Uniquely among the Hawaiian islands, Midway observes UTC-11 (also known as Samoa Time), eleven hours behind Coordinated Universal Time and one hour behind the state of Hawaiʻi. Midway Atoll is an unorganized, unincorporated territory of the United States, and the former home of the Midway Naval Air Station (former ICAO PMDY). It is less than 140 nautical miles (259 km; 161 mi) east of the International Date Line, about 2,800 nautical miles (5,200 km; 3,200 mi) west of San Francisco, and 2,200 nautical miles (4,100 km; 2,500 mi) east of Tokyo. It consists of a ring-shaped barrier reef and several sand islets. The two significant pieces of land, Sand Island and Eastern Island, are habitat for millions of seabirds. The island sizes are shown here:

Eastern Island 334 135
Spit Island 15 6
Midway Atoll 1,540 623

According to other sources, Sand Island measures 1,250 acres (5.1 km2) in area and the lagoon within the fringing rim of coral reef 9,900 acres (4,000 ha). The atoll, which has a small population (approximately 60 in 2009, but no indigenous inhabitants), is designated an insular area under the authority of the U.S. Department of the Interior. The Midway Atoll National Wildlife Refuge, encompassing 590,991.50 acres (239,165.77 ha)[1] of land and water (mostly water) in the surrounding area, is administered by the U.S. Fish and Wildlife Service (FWS). The visitor program reopened in January 2008 and there are facilities for visitors. Travel to the Atoll is possible through organized tour companies or as a FWS volunteer.[2][3] The tours focus on the ecology of Midway and the military history. The economy is derived solely from governmental sources and tourist fees. All food and manufactured goods are imported. The refuge and most of its surrounding area are part of the larger Papahānaumokuākea Marine National Monument.

Midway, as its name suggests, lies nearly halfway between North America and Asia, and almost halfway around the world from Greenwich, England. For statistical purposes, Midway is grouped as one of the United States Minor Outlying Islands.

Midway was the focus point of the Battle of Midway, one of the most important naval battles of the Pacific Campaign in World War II, fought on June 4–6, 1942. Nearby the islands, the United States Navy defeated a Japanese attack against the Midway Islands, marking a turning-point in the war in the Pacific Theater.

[edit] Geography and geology

Midway Atoll is part of a chain of volcanic islands, atolls, and seamounts extending from Hawai'i up to the tip of the Aleutian Islands and known as the Hawaii-Emperor chain. Midway was formed roughly 28 million years ago when the seabed underneath it was over the same hotspot from which the Island of Hawai'i is now being formed. In fact, Midway was once a shield volcano perhaps as large as the island of Lana'i. As the volcano piled up lava flows building the island, its weight depressed the crust and the island slowly subsided over a period of millions of years, a process known as isostatic adjustment. As the island subsided, a coral reef around the former volcanic island was able to maintain itself near sea level by growing upwards. That reef is now over 516 ft (160 m) thick (Ladd, Tracey, & Gross, 1967; in the lagoon, 1,261 feet (384 m), comprised mostly post-Miocene limestones with a layer of upper Miocene (Tertiary g) sediments and lower Miocene (Tertiary e) limestones at the bottom overlying the basalts. What remains today is a shallow water atoll about 6 miles (10 km) across.

The atoll has some 20 miles (32 km) of roads, 4.8 miles (7.8 km) of pipelines, one port on Sand Island (World Port Index Nr. 56328, MIDWAY ISLAND), and one active runway (rwy 06/24, around 8,000 feet (2,400 m) long). As of 2004, Henderson Field airfield at Midway Atoll has been designated as an emergency diversion airport for aircraft flying under ETOPS rules. Although the FWS closed all airport operations on November 22, 2004, public access to the island was restored beginning March 2008.[4]

Eastern Island Airstrip is a disused airfield in use by U.S. forces during the Battle of Midway, June 4–6, 1942. It is mostly constructed of Perforated Steel Plate sectional matting, built by the U.S. Navy Seabees.

[edit] History

[edit] Nineteenth century

The atoll was sighted on July 5, 1859 by Captain N.C. Middlebrooks, though he was most commonly known as Captain Brooks, of the sealing ship Gambia. The islands were named the "Middlebrook Islands" or the "Brook Islands". Brooks claimed Midway for the United States under the Guano Islands Act of 1856, which authorized Americans to occupy uninhabited islands temporarily to obtain guano. On 28 August 1867, Captain William Reynolds of the USS Lackawanna formally took possession of the atoll for the United States; the name changed to "Midway" some time after this. The atoll became the first Pacific islands annexed by the U.S. government, as the Unincorporated Territory of Midway Island, and administered by the United States Navy. Midway is the only island in the entire Hawaiian archipelago that was not later part of the State of Hawaii.

The buildings of the Commercial Pacific Cable Company date back to 1903 (2008)

The first attempt at "settlement" was in 1871, when the Pacific Mail Steamship Company started a project of blasting and dredging a ship channel through the reef to the lagoon using money put up by the United States Congress. The purpose was to establish a mid-ocean coaling station avoiding the high taxes imposed at ports controlled by the Hawaiians. The project was shortly a complete failure, and the USS Saginaw evacuated the last of the channel project's work force in October 1871. It then ran aground at Kure Atoll, stranding everyone on the ship. (All aboard were rescued with the exception of four who drowned in an attempt by five crew members to sail to Hawaii in an open boat to seek help. The party reached Kauai, but the boat was overturned just offshore and only William Halford survived and was able to bring help to the stranded).

[edit] Early twentieth century

Midway Atoll in November 1941.

In 1903, workers for the Commercial Pacific Cable Company took up residence on the island as part of the effort to lay a trans-Pacific telegraph cable. These workers introduced many non-native species to the island, including the canary, cycad, Norfolk Island pine, she-oak, coconut, and various deciduous trees, along with ants, cockroaches, termites, centipedes, and countless others.

Later that year, President Theodore Roosevelt placed the atoll under the control of the United States Navy, which on 20 January 1903 opened a radio station in response to complaints from cable company workers about Japanese squatters and poachers. Between 1904 to 1908 Roosevelt stationed 21 Marines on the island to end wanton destruction of bird life and keep Midway safe as a U.S. possession, protecting the cable station.

In 1935, operations began for the China Clippers, flying boats operated by Pan American Airlines. The Clippers island-hopped from San Francisco to China, providing the fastest and most luxurious route to the Orient and bringing tourists to Midway until 1941. Only the extremely wealthy could afford a Clipper trip, which in the 1930s cost more than three times the annual salary of an average American. With Midway on the route between Honolulu and Wake Island, the seaplanes landed in the atoll and pulled up to a float offshore in the lagoon. Tourists transferred to a small powerboat that ferried them to a pier, then rode in "woody" wagons to the Pan Am Hotel or the "Gooneyville Lodge", named after the ubiquitous "Gooney birds" (albatrosses).

[edit] World War II

The location of Midway in the Pacific became important to the military. Midway was a convenient refueling stop on transpacific flights, and was also an important stop for Navy ships. Beginning in 1940, as tensions with the Japanese were rising, Midway was deemed second only to Pearl Harbor in importance to protecting the U.S. west coast. Airstrips, gun emplacements and a seaplane base quickly materialized on the tiny atoll. The channel was widened, and Naval Air Station Midway was completed. Architect Albert Kahn designed the Officer's quarters, the mall and several other hangars and buildings. Midway was also an important submarine base. Midway's importance to the U.S. was brought into focus on December 7, 1941 with the Japanese attack on Pearl Harbor. Midway was attacked for the first time on December 7, 1941, and the Japanese force was successfully repulsed in the first American victory of the war. A Japanese submarine bombarded Midway on February 10, 1942.[5] Four months later, on June 4, 1942, a naval battle near Midway resulted in the U.S. Navy exacting a devastating defeat of the Japanese Navy. Four capital Japanese aircraft carriers, namely Akagi, Kaga, Hiryu and Soryu were sunk, along with the loss of hundreds of other Japanese aircraft, losses that the Japanese could not, and would never be able to replace. The US lost the aircraft carrier USS Yorktown (CV-5) in retaliation, along with a number of their carrier and land-based aircraft the Japanese either shot down or bombarded through dive-bombing towards the airfields by aircraft, mostly of Hiryu. The Battle of Midway was, by most accounts, the beginning of the end of the Japanese Navy's control of the Pacific Ocean.

From August 1, 1941 to 1945, it was occupied by U.S. military forces. In 1950, the Navy decommissioned Naval Air Station Midway, only to re-commission it again to support the Korean War. Thousands of troops on ships and planes stopped at Midway for refueling and emergency repairs. From 1968 to September 10, 1993, Midway Island was a Navy Air Facility. During the Cold War, the U.S. established an underwater listening post at Midway to track Soviet submarines. The facility remained secret until its demolition at the end of the Cold War. U.S. Navy WV-2 (EC-121K) "Willy Victor" radar planes flew night and day as an extension of the DEW Line (Distant Early Warning Line), and antenna fields covered the islands.

With about 3,500 people living on Sand Island, Midway also supported the U.S. troops during the Vietnam War. In June 1969, President Richard Nixon held a secret meeting with South Vietnamese President Nguyen Van Thieu at the Officer-in-Charge house or "Midway House".

[edit] Civilian jurisdiction

In 1978, the Navy downgraded Midway from a Naval Air Station to a Naval Air Facility and large numbers of personnel and dependents began leaving the island. With the war in Vietnam over, and with the introduction of reconnaissance satellites and nuclear submarines, Midway's significance to U.S.-national security was diminished. The World War II facilities at Sand and Eastern Islands were listed on the National Register of Historic Places on May 28, 1987.

Midway was designated an overlay National Wildlife Refuge on April 22, 1988 while still under the primary jurisdiction of the Navy. As part of the Base Realignment and Closure process, the Navy facility on Midway has been operationally closed since September 10, 1993, although the Navy assumed responsibility for cleaning up environmental contamination at Naval Air Facility Midway Island.

Beginning August 7, 1996, the general public could visit the atoll through study ecotours.[6] This program ended in 2002,[7] but another visitor program was approved and began operating in March 2008.[4][8]

On October 31, 1996, President Bill Clinton signed Executive Order 13022, which transferred the jurisdiction and control of the atoll to the U.S. Department of the Interior. The Fish and Wildlife Service assumed management of the Midway Atoll National Wildlife Refuge. The last contingent of Navy personnel left Midway on June 30, 1997 after an ambitious environmental cleanup program was completed.

On June 15, 2006, President George W. Bush designated the Northwestern Hawaiian Islands as a national monument. The Northwestern Hawaiian Islands Marine National Monument encompasses 105,564 square nautical miles (139,798 sq mi; 362,074 km2), and includes 3,910 square nautical miles (5,178 sq mi; 13,411 km2) of coral reef habitat.[9] The Monument also includes the Hawaiian Islands National Wildlife Refuge, and the Midway Atoll National Wildlife Refuge.

In 2007, the Monument's name was changed to Papahānaumokuākea (pronounced PA-pa-ha-NOW-mo-KOO-ah-KAY-uh) Marine National Monument.[10] The National Monument is managed by the U.S. Fish and Wildlife Service, the National Oceanic and Atmospheric Administration (NOAA), and the State of Hawaii.

[edit] Wildlife

Albatrosses at Midway Atoll.

Midway Atoll is now home to 67-70% of the world's Laysan Albatross population, and 34-39% of the global black-footed albatross.[11]

While Midway supports nearly three million birds, each seabird species has carved out a specific site on the atoll in which to nest. Seventeen different species of seabird can be found, the rarest of which is the short-tailed albatross, otherwise known as the “Golden Gooney.” Fewer than 2,200 are believed to exist due to excessive feather hunting in the late nineteenth century.[12]

Over 250 different species of marine life are found in the 300,000 acres (1,200 km2) of lagoon and surrounding waters. The critically endangered Hawaiian Monk Seals raise their pups on the beaches. Monk seals are benthic foragers and rely on the Midway Atoll’s reef fish, squid, octopus and crustaceans. Green sea turtles, another threatened species, occasionally nest on the island. The first was found in 2006 on Spit Island and another in 2007 on Sand Island. A resident pod of 300 spinner dolphins live in the lagoons and nearshore waters.[13]

Ironwood trees from Australia were planted to act as windbreaks. Seventy-five percent of the 200 species of plants on Midway were introduced. The FWS has recently re-introduced the endangered Laysan duck (Midway is part of its assumed pre-historic range) to the Atoll, while at the same time extending efforts to exterminate invasive plant species.

[edit] Environmental issues

Marine debris with Laysan albatross chicks.

The islands of Midway Atoll have been extensively altered as a result of human habitation. Starting in 1869 with a project to blast the reefs and create a port on Sand Island, the ecology of Midway has been changing.

[edit] Marine debris

Midway Atoll, in common with all the Hawaiian Islands, receives substantial amounts of marine debris from the Great Pacific Garbage Patch. Consisting of ninety percent plastic, this debris accumulates on the beaches of Midway. This garbage represents a hazard to the bird population of the island.

Of the 1.5 million Laysan Albatrosses that inhabit Midway, nearly all are found to have plastic in their digestive system.[14] Approximately one-third of the chicks die.[15]

[edit] Lead poisoning

Lead paint on the buildings still poses an environmental hazard (Avian lead poisoning) to the albatross population of the island. The cost of stripping the paint is estimated to be $5 million.[16] It was announced in September 2010, that the Federal Government would plan to carry out the clean up by July 2011.[17]

[edit] 2011 Tsunami

The 2011 Tōhoku earthquake and tsunami caused many deaths among the bird population on Midway.[18] Researchers had ample warning prior to the tsunami. Scientists on the island however do not think it will have long-term negative impacts on the bird populations.

[edit] Transportation

The usual method of reaching Sand Island, Midway Atoll's only populated island, is via Henderson Field Airport. (copy of wikipedia)

Kingman Reef (play /ˈkɪŋmən/) is a largely submerged, uninhabited triangular shaped reef, 9.5 nautical miles (18 km) east-west and 5 nautical miles (9 km) north-south,[1] located in the North Pacific Ocean, roughly half way between the Hawaiian Islands and American Samoa at 6°23′N 162°25′W / 6.383°N 162.417°W / 6.383; -162.417.[2][3] It is the northernmost of the Northern Line Islands and lies 36 nautical miles (67 km) northwest of the next closest island (Palmyra Atoll), and 930 nautical miles (1,720 km) south of Honolulu.[2]

The reef encloses a lagoon up to 270 feet (82 m) deep in its western part.[1] The total area within the outer rim of the reef is 76 km2 (29 sq mi). There are two small strips of dry land composed of coral rubble and giant clamshells on the eastern rim with areas of 2 acres (8,000 m2) and 1 acre (4,000 m2)[4] having a coastline of 3 kilometres (2 mi).[2] The highest point on the reef is less than 5 feet (1.5 m) above sea level,[4] which is wetted or awash most of the time, making Kingman Reef a maritime hazard. It has no natural resources and supports no economic activity.[2]

[edit] Political status

Kingman Reef has the status of an unincorporated U.S. possession of the United States, administered from Washington, DC by the U.S. Department of Interior. The atoll is closed to the public. For statistical purposes, Kingman Reef is grouped as part of the United States Minor Outlying Islands. In January 2009, Kingman Reef was designated a marine national monument.

The pre-20th century names Danger Reef, Caldew Reef, Maria Shoal and Crane Shoal refer to this atoll, which by then was entirely submerged at high tide. Thomas Hale Streets described its state in the 1870s, when it had:

... hardly, as yet, assumed the distinctive features of an island. It is entirely under water at high tide, and but a few coral heads project here and there above the surface at low water. In the course of time, however, it will undoubtedly be added to the [northern Line Islands].[5]

[edit] History

Kingman Reef was discovered by the American Captain Edmund Fanning of the ship Betsey on June 14, 1798. Captain W. E. Kingman (whose name the island bears) described it on November 29, 1853. It was claimed for the United States under the name "Danger Reef" by the Guano Islands Act of 1856.[6]

Lorrin A. Thurston formally annexed Kingman to the United States on May 10, 1922 by reading this declaration on shore:

Be it known to all people: That on the tenth of May, A.D. 1922, the undersigned agent of the Island of Palmyra Copra Co., Ltd., landed from the motorship Palmyra doth, on this tenth day of May, A.D. 1922, take formal possession of this island, called Kingman Reef, situated in longitude 162 degrees 18' west and 6 degrees 23' north, on behalf of the United States of America and claim the same for said company.

The lagoon was used in 1937 and 1938 as a halfway station between Hawai'i and American Samoa by Pan American Airways flying boats (Sikorsky S-42B).[7] Pan Am wanted to expand flights into the Pacific and include Australia and New Zealand to their "Clipper" air routes. In 1935 it was decided that the lagoon at Kingman Reef was suitable for overnight stops en route from the U.S to New Zealand via Samoa. Kingman Reef became the stopover to and from Pago Pago, American Samoa, located 1,600 miles (2,600 km) further south. A supply ship, the North Wind, was stationed at Kingman Reef to provide fuel, lodging, and meals. The S42B Pan American Clipper II, piloted by Captain Edwin Musick, landed at Kingman on its first flight on March 23, 1937. Several successful flights followed, however the flight on January 11, 1938 ended in tragedy. Shortly after the early morning take off from Pago Pago, bound for New Zealand the Clipper exploded. The right outboard engine developed an oil leak and the plane burst into flames while dumping fuel, and there were no survivors. As a result of the tragedy, Pan Am ended flights to New Zealand via Kingman Reef and Pago Pago. A new route was established in July 1940 by way of Canton Island and New Caledonia.

On December 29, 1934 the US Navy assumed jurisdiction over Kingman Reef.[8] On September 1, 2000 the Navy relinquished its control over Kingman Reef to the US Department of the Interior and on January 18, 2001 the Secretary of the Interior signed Secretary’s Order 3223 establishing Kingman Reef as a National Wildlife Refuge including 1,958 km2 (484,000 acres). The National Wildlife Refuge is composed of the emergent coral rubble spits and all waters out to 12 nautical miles (22 km). In January 2009, Kingman Reef was designated a marine national monument.[4]

[edit] Amateur radio expeditions

Since the early 1940s Kingman Reef has had very little human contact, though amateur radio operators from around the world have occasionally visited the reef to put it "on the air" in what is known as a DX-pedition. In 1974, a group of amateurs using the callsign KP6KR sailed to the reef and set up a temporary radio station and antenna tower. Other groups visited the island in subsequent years, including 1977, 1980, 1981, 1988 and 1993.

Most recently, a group of 15 amateur radio operators from the Palmyra DX Group visited the reef in October 2000. Using the FCC-issued special event callsign K5K, the group made more than 80,000 individual contacts with amateurs around the world over a period of 10 days.[9]

[edit] Ecology

Dry strip of land on Kingman Reef. Note coconut palm seedling.

Kingman Reef supports a vast variety of marine life. Giant clams are abundant in the shallows, and there are approximately 38 genera and 130 species of stony corals present on the reef. This is more than three times the species diversity of corals found in the main Hawaiian Islands. The ecosystem of the reef and its subsequent food chain are known for the distinct quality of being primarily predator-based. The percentage of the total fish biomass on the reef is made up of 85% apex predators, creating a high level of competition for food and nutrients among local organisms — particularly sharks, jacks and other carnivores. The threatened green sea turtles that frequent nearby Palmyra atoll travel to Kingman Reef to forage and bask on the coral rubble spits at low tide.

Above sea level the reef is usually barren of macroorganisms, however. Mainly constructed of dead and dried coral skeletons, providing only calcite as a source of nutrients, the small and narrow strips of dry land are only habitable by a handful of species for short periods of time. Most flora which begin to grow above water — primarily coconut palms — die out quickly due to the fierce tides and lack of resources necessary to sustain plant life.

Johnston Atoll is a 1.03 sq mi (2.7 km2) atoll in the North Pacific Ocean[1] about 750 nmi (860 mi; 1,390 km) west of Hawaii. There are four islands located on the coral reef platform, two natural islands, Johnston Island and Sand Island, which have been expanded by coral dredging, as well as North Island (Akau) and East Island (Hikina), an additional two artificial islands formed by coral dredging.[1]

Johnston is an unincorporated territory of the United States, administered by the United States Fish and Wildlife Service of the Department of the Interior as part of the Pacific Remote Islands Marine National Monument. For statistical purposes, Johnston Atoll is grouped as one of the United States Minor Outlying Islands.

The American brig Sally—captained by Joseph Pierpont—grounded on a shoal near Johnston Island on September 2, 1796, but did not name or claim the land.[2] The island was named for Captain Charles J. Johnston, commanding officer of HMS Cornwallis, who claimed its official discovery on December 14, 1807. Johnston Atoll was claimed by both the United States and the Kingdom of Hawaii in 1858. The atoll's guano deposits, mined by U.S. interests operating under the Guano Islands Act, were worked until depletion in about 1890.

The island was visited from July 10-22, 1923, and a pioneering aerial photograph was taken then.

On July 29, 1926, by Executive Order, President Calvin Coolidge established Johnston Atoll as a federal bird refuge and placed it under the control of the U.S. Department of Agriculture. On December 29, 1934, President Franklin D. Roosevelt transferred control of Johnston Atoll to the United States Navy in order to establish an air station, and also to the Department of the Interior to administer the bird refuge. In 1936, the Navy began to develop a seaplane base, an airstrip base, and refueling facilities on the atoll. Johnston Atoll was designated as a Naval Defensive Sea Area and Airspace Reservation on 14 February 1941. Johnston Atoll was shelled by lightly armed Japanese submarines once or twice during World War II.

The Johnston Atoll area was used during the 1950s and 1960s as an American nuclear weapons test site—for both above-ground and underground nuclear tests. It was also used for a rocket launch site for some of the first American spy satellites. Later on, it became the site of a chemical weapons depot and the site of the Johnston Atoll Chemical Agent Disposal System (JACADS). All of the chemical weapons that were once stored on Johnston Island have been incinerated, and that process was completed in 2000 and JACADS demolished by 2003.

Between 1958 and 1975, several scientific sounding rockets were launched from Johnston Island.[3] There were also several nuclear test missiles that were launched from Johnston Island in 1962 during the "Operation Dominic" series of nuclear tests, from a launchpad at 16°44′13″N 169°31′26″W / 16.7370°N 169.5240°W / 16.7370; -169.5240. Twelve thermonuclear warheads were exploded in all, one of which failed when the PGM-17 Thor carrying it failed to launch and scattered plutonium debris over the island. Afterwards, the radioactive debris and soils were placed in a 25 acres (100,000 m2) landfill on the island, along with residue from Agent Orange containers returned from Southeast Asia after the Vietnam War, PCBs, PAHs, dioxins, and sarin nerve gas from the Soviet Union and East Germany.

Growth of Johnston Island by coral dredging

In 1963, the U.S. Senate ratified the Limited Test Ban Treaty, which contained a provision known as "Safeguard C". Safeguard C was the basis for maintaining Johnston Atoll as a "ready to test" above-ground nuclear testing site should atmospheric nuclear testing ever be deemed to be necessary again. In 1993, Congress appropriated no funds for the Johnston Atoll "Safeguard C" mission, bringing it to an end. Congress redefined the island's military mission as the storage and destruction of chemical weapons.

Johnston Atoll has never had any indigenous inhabitants, although during the late part of the 20th century, there were averages of about 300 American military personnel and 1,000 civilian contractor men present at any given time.[1]

The central means of transportation to this island was the airport, which had a paved military runway. The islands were wired with 13 outgoing and 10 incoming commercial telephone lines, a 60-channel submarine cable, 22 DSN circuits by satellite, an Autodin with standard remote terminal, a digital telephone switch, the Military Affiliated Radio System (MARS station), a UHF/VHF air-ground radio, and a link to the Pacific Consolidated Telecommunications Network (PCTN) satellite.[citation needed] Amateur radio operators occasionally transmitted from the island, using the KH3 callsign prefix.

Johnston Atoll's economic activity was limited to providing services to American military personnel and the contractors residing temporarily on the island. All foodstuffs and manufactured goods were imported. The base had six 2.5 megawatt (MW) electrical generators supplied by the base's support contractor, Holmes and Narver, using Enterprise Engine and Machinery Company DSR-36 diesel engines. The runway was also available to commercial airlines for emergency landings (a fairly common event), and for many years it was a regular stop on Continental Micronesia airline's "island hopper" service between Hawaii and the Marshall Islands.

Approaching the runway on Johnston Island from the northeast with Sand Island partially visible on the right. The base was closed and the airport deactivated on June 15, 2004.

In 2003, all structures and facilities, including those used in JACADS, were removed, and the runway was marked closed. On August 22, 2006, Johnston Island was struck by Hurricane Ioke. The eastern eye-wall passed directly over the atoll, with winds exceeding 100 mph (160 km/h).

On December 9, 2007, the United States Coast Guard swept the runway at Johnston Island of debris and used the runway in the removal and rescue of an ill Taiwanese fisherman to Oahu, Hawaii. The fisherman was transferred from the Taiwanese fishing vessel Sheng Yi Tsai No. 166 to the Coast Guard buoy tender Kukui on December 6, 2007. The fisherman was transported to the island, and then picked up by a Coast Guard C-130 Hercules rescue plane from Kodiak, Alaska.[4]

Johnston Atoll is a part of the Pacific Remote Islands Marine National Monument, which was proclaimed by President George W. Bush on January 6, 2009.

The four islands compose a total land mass of 2.67 km².[1] Due to the atoll's tilt, much of the reef on the southeast portion has subsided. But even though it does not have an encircling reef crest, the reef crest on the northwest portion of the atoll does provide for a shallow lagoon, with depths ranging from 3–10 m (9.8–33 ft).

Its climate is tropical but generally dry. Northeast trade winds are consistent and there is little seasonal temperature variation.[1] With elevation ranging from sea level to 5 m (16 ft) at Summit Peak, the islands contain some low-growing vegetation on mostly flat terrain and no natural fresh water resources.[1]

[edit] Wildlife

About 300 species of fish have been recorded from the reefs and inshore waters of the atoll. It is also visited by Green Turtles and Hawaiian Monk Seals. Seabird species recorded as breeding on the atoll include Bulwer's Petrel, Wedge-tailed Shearwater, Christmas Shearwater, White-tailed Tropicbird, Red-tailed Tropicbird, Brown Booby, Red-footed Booby, Masked Booby, Great Frigatebird, Gray-backed Tern, Sooty Tern, Brown Noddy, Black Noddy and White Tern. It is visited by migratory shorebirds, including the Pacific Golden Plover, Wandering Tattler, Bristle-thighed Curlew, Ruddy Turnstone and Sanderling.[5]

[edit] License plates

There were no official license plates issued for use on Johnston Atoll. U.S. government vehicles were issued U.S. government license plates and private vehicles retained the plates from which they were registered. According to reputable license plate collectors, a number of "Johnston Atoll license plates" were created as souvenirs, and have even been sold on-line to collectors, but they were not officially issued.[6][7]
