The Dumoulin Islands (66°37′S 140°4′E / 66.617°S 140.067°E / -66.617; 140.067Coordinates: 66°37′S 140°4′E / 66.617°S 140.067°E / -66.617; 140.067) are a small group of rocky islands at the northeast end of the Geologie Archipelago, 2.5 nautical miles (4.6 km) north of Astrolabe Glacier Tongue. A French expedition under Captain Jules Dumont d'Urville landed on one of these islands, Rocher du Débarquement, on January 22, 1840. Dumont d'Urville named so the group of islands including the Rocher du Débarquement in honor of the Hydrographer of the expedition, Clément Adrien Vincendon-Dumoulin (fr). The islands were roughly charted by the Australasian Antarctic Expedition, 1911–14, under Mawson, who named them after Clément Adrien Vincendon-Dumoulin (fr), of the French expedition who conducted observations on terrestrial magnetism in this locality. The group was photographed from the air by U.S. Navy Operation Highjump, 1946–47, and recharted by the French Antarctic Expedition under André-Frank Liotard, 1949–51.[1]
