Débarquement Rock
Débarquement Rock is an ice-free rock long and 18.7 m high, marking the northern end of the Dumoulin Islands and the north-eastern end of the Geologie Archipelago. History The French Antarctic Expedition, 1837–40, under Captain Jules Dumont d'Urville landed on the western side of the highest of the westernmost rocky islets, to which he gave the name "''Rocher du Débarquement''". The landing was described by him as taking place on 21 January 1840 at 9 in the evening, though the actual date was 22 January 1840, since d'Urville had forgotten to add a day on his diary when he passed the 180° meridian from the east. Identification of the islet with d'Urville's "''Rocher du Débarquement''" has been made on the basis of aerial photographs taken in the course of the US Navy's Operation Highjump (1946–1947), and of surveys and geological studies made by the French Antarctic Expedition in 1950–1952, with the seaward position of Débarquement Rock correlating with the feature ...

Dumoulin Islands
The Dumoulin Islands are a small group of rocky islands in the Antarctic region at the northeast end of the Geologie Archipelago, north of Astrolabe Glacier Tongue. On 22 January 1840, a French Antarctic expedition led by Captain Jules Dumont d'Urville, aboard his flagship ''Astrolabe'', landed a party on one of these islands, Rocher du Débarquement. Dumont d'Urville named the group of islands in honor of the hydrographer of his expedition, Clément Adrien Vincendon-Dumoulin. The islands were roughly charted by the Australasian Antarctic Expedition, 1911–14, under Mawson. The island group was photographed from the air by U.S. Navy Operation Highjump Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV.

French Antarctic Expedition, 1837–40
The French Antarctic Expedition is any of several French expeditions in Antarctica. First expedition In 1772, Yves-Joseph de Kerguelen-Trémarec and the naturalist Jean Guillaume Bruguière sailed to the Antarctic region in search of the fabled Terra Australis. Kerguelen-Trémarec took possession of various Antarctic territories for France, including what would later be called the Kerguelen Islands. In Kerguelen-Trémarec's report to King Louis XV, he greatly overestimated the value of the Kerguelen Islands. The King sent him on a second expedition to Kerguelen in late 1773. When it became clear that these islands were desolate, useless, and not the Terra Australis, he was sent to prison. Second expedition In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife. During the Antarctic part of this expedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Dumont D'Urville
Jules Sébastien César Dumont d'Urville (; 23 May 1790 – 8 May 1842) was a French explorer and naval officer who explored the south and western Pacific, Australia, New Zealand, and Antarctica. As a botanist and cartographer, he gave his name to several seaweeds, plants and shrubs, and places such as d'Urville Island in New Zealand. Childhood Dumont was born at Condé-sur-Noireau in Lower Normandy. His father, Gabriel Charles François Dumont, sieur d’Urville (1728–1796), Bailiff of Condé-sur-Noireau, was, like his ancestors, responsible to the court of Condé. His mother Jeanne Françoise Victoire Julie (1754–1832) came from Croisilles, Calvados, and was a rigid and formal woman from an ancient family of the rural nobility of Lower Normandy. The child was weak and often sickly. After the death of his father when he was six, his mother's brother, the Abbot of Croisilles, played the part of his father and from 1798 took charge of his education. The Abbot taugh ...

Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The operation was organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Ethan Erik Larson, USN, Commanding Officer, Task Force 68. Operation HIGHJUMP commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. HIGHJUMP's objectives, according to the U.S. Navy report of the operation, were: # Training personnel and testing equipment in frigid conditions; # Consolidating and extending the United States' sovereignty over the largest practicable area of the Antarctic continent (publicly denied as a goal before the expedition ended); # Determining the feasibility of establishing, maintaining, and utilizing bases in the Antarctic an ...

Astrolabe Glacier
Astrolabe Glacier is a glacier wide and long, flowing north-northeast from the continental ice and terminating at the coast in a prominent tongue at the east side of Geologie Archipelago. It was first sighted in 1840 by the French expedition under Captain Jules Dumont d'Urville, although no glaciers were noted on d'Urville's chart of this coast but a formidable icy dike with perpendicular flanks of 37.7 m high according to the joined plate, corresponding to the glacier tongue. The glacier was photographed from the air by U.S. Navy Operation Highjump in January 1947. It was charted by the French Antarctic Expedition, 1949–51, and named after d'Urville's flagship, the ''Astrolabe''. The Astrolabe Glacier Tongue () is a prominent glacier tongue about wide and long, extending northeast from Astrolabe Glacier.
