Subantarctic Islands characteristics

Hemisphere_Sud.png2

Located at the margins of the Indian and Southern Oceans, the French islands Crozet, Kerguelen, Amsterdam and Saint-Paul are together designated as an Overseas Territory. They are organized into three districts over which sovereignty is exercised by the French Southern and Antarctic Lands (Terres Australes et Antarctiques Françaises, TAAF).

There is no permanent population in these districts, but each one has a scientific research station. The TAAF administration is responsible for the general management of these bases. Whereas IPEV is in charge of the scientific programmes developed there.

Supply and backup services for the subantarctic stations are assured by the research vessel Marion Dufresne based on Réunion Island. Relief services are run throughout the year, but the Southern summer sees the most intense logistical activity. Other ships also make regular trips to these islands, usually related to fishing operations undertaken in the exclusive economic zones (EEZ) centred on the TAAF.
