French Frigate Shoals
The French Frigate Shoals (Hawaiian: Kānemilohaʻi) 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 feet (36 m) high La Perouse Pinnacle, the only remnant of its volcanic origins. The total land area of the islets is 61.508 acres (248,910 m2). Total coral reef area of the shoals is over 232,000 acres (940 km2). Tern Island, with an area of 26.014 acres (105,270 m2), 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 (902 km/560 mi) northwest of Honolulu.

History
Although there is no evidence of extensive human activity or presence in the area, the earliest human visitors to French Frigate Shoals probably came from the larger Hawaiian Islands, which were settled by Polynesians between 1100 and 1300 AD.
The Hawaiian island chain lay outside the routes followed by early European explorers, and it was not until La Pérouse's near-disastrous discovery that the shoals were known to the outside world. La Pérouse, aboard the frigate Boussole, was sailing westward from Monterey en route to Macau. During the night of November 6 1786, sailors sighted breakers directly in their path, about a thousand feet ahead. Both the Boussole and her companion vessel, the frigate Astrolabe, were immediately brought about, passing within a few hundred feet of the breakers. At daybreak, the ships returned and mapped the southeastern half of the atoll, as well as finding the rock that would later be named after La Pérouse. La Pérouse named the shoals Basse des Fregates Françaises, the "Shoal of the French Frigates".
During the late 1800s, American and European companies became interested in the possibility of mining guano in the Hawaiian Islands. U.S. Navy Lieutenant John M. Brooke, sailing on the naval schooner Fenimore Cooper, formally took possession of French Frigate Shoals for the United States on 14 January 1859, in accordance with the Guano Islands Act. In 1894, French Frigate Shoals, Kure Atoll, Midway Atoll, and Pearl and Hermes Reef were leased for 25 years by the Republic of Hawaii to the North Pacific Phosphate and Fertilizer Company; however, guano and phosphate deposits at French Frigate Shoals were found to be impractical to mine. Oddly enough, the Republic did not formally claim possession of the shoals until July 13, 1895.
French Frigate Shoals was included among the islands acquired by the United States on July 7, 1898, when Hawaii became a United States Territory. In 1909 it was made a part of the Hawaiian Islands Bird Reservation.
World War II
During the early months of the U.S.-Japanese conflict in World War II, Japanese seaplanes occasionally used French Frigate Shoals as a rendezvous point for refuelling by submarine. By mid-1942, increasing U.S. naval activity in the area prevented further Japanese use. After the Battle of Midway, the U.S. Navy built a Naval Air Station on Tern Island, enlarging the island sufficiently to support a 3,300 feet (1,005 m) landing strip. The Station's main function was as an emergency landing site for planes flying between Hawaii and Midway Atoll. The original seawall, runway, and some of the buildings remain. Tern Island has a land area of 26.014 acres (105,270 m2).
The United States Fish and Wildlife Service continues to maintain a permanent field station there. In 2000, the atoll became part of the Northwestern Hawaiian Islands Coral Reef Ecosystem Reserve, which was incorporated into the Northwestern Hawaiian Islands National Monument in 2006.
Ecology
The reef system at French Frigate Shoals supports 41 species of stony corals, including several species that are not found in the main Hawaiian Island chain. More than 600 species of marine invertebrates, many of which are endemic, are found here as well.
More than 150 species of algae live among the reefs. Especially diverse algal communities are found immediately adjacent to La Perouse Pinnacle. This has led to speculation that an influx of additional nutrients — in the form of guano — is responsible for the diversity and productivity of algae in this environment. The reef waters support large numbers of fish. The masked angelfish (Genicanthus personatus), endemic to the Hawaiian Islands, is relatively common here. Most of Hawaii's green sea turtles travel to the shoals to nest. The small islets of French Frigate Shoals provide refuge to the largest surviving population of Hawaiian monk seals, the second most endangered pinniped in the world.
The islands are also an important seabird colony. 18 species of seabird, the Black-footed Albatross, Laysan Albatross, Bonin Petrel, Bulwer's Petrel, Wedge-tailed Shearwater, Christmas Shearwater, Tristram's Storm-petrel, Red-tailed Tropicbird, Masked Booby, Red-footed Booby, Brown Booby, Great Frigatebird, Gray-backed Tern, Sooty Tern, Blue-gray Noddy, Brown Noddy, Black Noddy and White Tern nest on the islands, most of them (16) of them on Tern Island. Two species, the Blue-gray Noddy and the Brown Booby, nest only on La Perouse Pinnacle. The island also is the wintering ground for several species of shorebird.
A three-week research mission in October 2006 by the National Oceanic & Atmospheric Administration (NOAA) led to the discovery of 100 species never seen in the area before, including many that are totally new to science. The research findings will be used to establish what species live in the area. Further studies will also determine how well the shoals' ecosystem is being managed and the threats it faces. The French Frigate Shoals project is part of the Census of Coral Reef Ecosystems of the International Census of Marine Life.
Whale-Skate Island is a submerged island in the French Frigate Shoals. These islands suffered considerably from erosion starting in the 1960s, and by the late 1990s, Whale-Skate Island was completely washed over.
