Clipperton Island

Clipperton Island is an uninhabited coral atoll in the eastern Pacific, southwest of Mexico. France administers it as an overseas state property.

Clipperton Island sovereignty dispute: A dispute over sovereignty of Clipperton Island, settled by an Italian arbitration award in 1931. The award confirmed France’s claim after competing claims by Mexico and other states.
Atoll: A ring-shaped coral reef or island enclosing a lagoon, usually built around a subsiding volcanic island. Clipperton is a small, low atoll rather than a continental island.
Island biogeography: The study of how island area, isolation, and habitat affect the distribution and diversity of species. Clipperton’s distance from continents makes its species patterns useful for comparison.
Revillagigedo Islands: A Mexican Pacific archipelago southwest of Baja California, comprising four volcanic islands. This Mexican island group lies in the same broad eastern Pacific region.
Clipperton Island guano mining: The commercial extraction of seabird guano from Clipperton Island, especially during the late nineteenth century. Guano exports drew workers and infrastructure to an otherwise remote atoll.
Coral reef: A marine ecosystem and geological structure built largely by reef-forming corals and their calcium carbonate skeletons. Reef growth created the island’s encircling rim.
Seabird colony: A group of seabirds that nests or roosts together at a shared site. Monitoring the colony helps track ecological change across the atoll.
French overseas possessions: Territories under French sovereignty located outside metropolitan France. Clipperton is a French possession administered separately from an inhabited overseas collectivity.
Clipperton Island colony: A small Mexican settlement established on Clipperton Island to support guano extraction and maintain Mexico’s claim. The colony’s wartime abandonment left survivors isolated until their rescue in 1917.
Lagoon: A shallow body of water separated from the open sea by a reef, barrier island, or other landform. Clipperton’s central lagoon is enclosed by its reef rim.
