Prince Edward Islands
The Prince Edward Islands are a remote South African archipelago in the southern Indian Ocean, comprising Marion Island and Prince Edward Island.
Marion Island: A volcanic island in the southern Indian Ocean and the larger, inhabited island of the Prince Edward Islands. Its research station and wildlife studies anchor most sustained human activity in the archipelago.
Shield volcano: A broad volcano built mainly from repeated flows of low-viscosity basaltic lava. Marion Island’s volcanic landforms were built by eruptions of this general type.
Prince Edward Islands Marine Protected Area: A South African protected marine area surrounding the Prince Edward Islands. Its restrictions protect marine habitats and wildlife around the archipelago.
King penguin: A large subantarctic penguin species that breeds in colonies on islands across the Southern Ocean. King penguins are among the conspicuous breeding seabirds on Marion Island.
Subantarctic: The oceanic region and islands between the temperate South Atlantic, Indian, and Pacific oceans and the Antarctic region. The islands’ climate and biota belong to this cold, stormy zone north of Antarctica.
Plate tectonics: The theory that Earth’s outer shell consists of moving plates whose interactions shape the planet’s surface. The islands’ volcanic setting reflects processes at the boundary between major oceanic plates.
Marion Island research station: South Africa’s permanent research station on Marion Island. It enables year-round monitoring of weather, ecosystems, and wildlife.
Antarctic fur seal: A fur seal species that breeds on subantarctic islands in the Southern Ocean. Its populations on the islands recovered after historical sealing.
South African National Antarctic Programme: South Africa’s government programme for Antarctic and subantarctic research and logistics. It supports South African research and station operations on Marion Island.
Oceanic climate: A climate moderated by the ocean, typically with small temperature ranges, persistent moisture, and strong winds. Surrounding waters and frequent westerlies produce the islands’ cool, wet conditions.
