Site description The Duroch Islands lie several hundred metres offshore from Cape Legoupil, northwestern Trinity Peninsula, northern Antarctic Peninsula. The island group includes Wisconsin Islands in the northeast and extends to Estay Rock in the southwest, and excludes Demas Rocks (Hattersley-Smith, 1991).

The nearest permanent scientific facility is Bernardo O’Higgins Station (Chile), which has capacity for ~44 people and operates year-round ~200 m to the south at Cape Legoupil (COMNAP, Antarctic Facilities, accessed 20/08/2010).
