Site description The Joubin Islands are an archipelago comprising numerous small islands, islets and offshore rocks situated ~5 km from Cape Monaco, southwestern Anvers Island. The islands were first charted by the French Antarctic Expedition in 1903-05 (Hattersley-Smith, 1991).

The Joubin Islands are designated as a Restricted Zone under Antarctic Specially Managed Area No. 7: Southwest Anvers Island and Palmer Basin, which includes the marine area extending to a 50 m buffer around the outer shorelines. The IBA covers the area defined by the boundary of the Restricted Zone.

Detailed information on the Joubin Islands environment is not available. The geology shares a granitic and volcanic origin with Anvers Island. Vegetation is typical of the region, and consists of a wide range of mosses, lichens and algae, as well as the native vascular plants Antarctic hairgrass (Deschampsia antarctica) and the pearlwort Colobanthus quitensis (ASMA No. 7 Management Plan, 2009).

The nearest permanent scientific station is Palmer (US), situated ~15 km to the east at Arthur Harbour, southern Anvers Island. Climate data specifically for the Joubin Islands are not available. See Ant012 for more information on Palmer Station and local climate.
