Île Amsterdam (French pronunciation: [ilamstəʁˈdam], also known as Amsterdam Island, New Amsterdam, or Nouvelle Amsterdam, is an island named after the city of Amsterdam in the Netherlands. It lies in the southern Indian Ocean. It is part of the French Southern and Antarctic Lands and, together with neighbouring Île Saint-Paul 85 km (53 mi) to the south, forms one of the five districts of the territory. Its base, the Martin-de-Viviès research station, first called Camp Heurtin, then La Roche Godon, and the only settlement on the island, is the capital of the territory and is home to about 30 (non-permanent) inhabitants involved in biological, meteorological and geomagnetic studies.
