GeoTag[1] Petrel Island (French: Île des Pétrels) is a rocky island, 900 m long and 45 m in elevation, which lies north-west of Rostand Island and is the largest feature in the cluster of islands at the south-eastern end of Geologie Archipelago. It was photographed from the air by U.S. Navy Operation Highjump, 1946-47, charted by the French Antarctic Expedition, 1949-51, and so named by them because numerous Snow Petrel nests present. In January 1952, following destruction of the Port Martin base by fire, the French Antarctic Expedition under Marret, 1952-53, enlarged the hut on Petrel Island to serve as the new base site. The island is now the site of Dumont d'Urville Station.
