Mount Martine
Mount Martine is a massive mountain, about high, with a prominent rocky north face and ice-covered south slopes, overlooking the north shore of Charcot Island, south of Cheesman Island, in the east Bellinghausen Sea of Antarctica. History It was discovered and roughly mapped on 11 January 1910, by the Fourth French Antarctic Expedition under Jean-Baptiste Charcot, and named by him in association with Mount Monique and the Marion Nunataks after his daughter, Martine. It was photographed from the air on 9 February 1947 in the course of the US Navy's Operation Highjump and mapped from these photographs by D.

Charcot Island
Charcot Island or Charcot Land is an island administered under the Antarctic Treaty System, long and wide, which is ice covered except for prominent mountains overlooking the north coast. Charcot Island lies within the Bellingshausen Sea, west of Alexander Island, and about north of Latady Island. A notable landmark of the island is its northernmost point, Cape Byrd. History Charcot Island was discovered on 11 January 1910 by the French Antarctic Expedition under Jean-Baptiste Charcot, who, at the insistence of his crew and the recommendation of Edwin S. Balch and others, named it Charcot Land. He did so with the stated intention of honoring his father, Jean-Martin Charcot, a famous French physiciaThe insularity of Charcot Land was proved by Sir Hubert Wilkins, who flew around it on 29 December 1929. 2009 Collapse of ice bridge The ice bridge holding the Wilkins Ice Shelf to the Antarctic coastline and Charcot Island was long but only wide at its narrowest point – in 1 ...

Cheesman Island
Cheesman Island is a small rocky island off the north coast of Charcot Island, north of Mount Martine. It was first seen and photographed from the air in 1929 by Sir Hubert Wilkins, who roughly positioned it. It was remapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, by D. Searle of the Falkland Islands Dependencies Survey in 1960. The name was suggested by the Advisory Committee on Antarctic Names The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica.

Bellinghausen Sea
The Bellingshausen Sea is an area along the west side of the Antarctic Peninsula between 57°18'W and 102°20'W, west of Alexander Island, east of Cape Flying Fish on Thurston Island, and south of Peter I Island (there the southern ''Vostokkysten'').

Fourth French Antarctic Expedition
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 exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Charcot
Jean-Baptiste-Étienne-Auguste Charcot (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). Life Jean-Baptiste Charcot was appointed leader of the French Antarctic Expedition with the ship ''Français'' exploring the west coast of Graham Land from 1904 until 1907. The expedition reached Adelaide Island in 1905 and took pictures of the Palmer Archipelago and Loubet Coast. From 1908 until 1910, another expedition followed with the ship '' Pourquoi Pas ?'', exploring the Bellingshausen Sea and the Amundsen Sea and discovering Loubet Land, Marguerite Bay, Mount Boland and Charcot Island, which was named after his father, Jean-Martin Charcot. anhere./ref> He named Hugo Island after Victor Hugo, the grandfather of his wife, Jeanne Hugo.

Marion Nunataks
The Marion Nunataks are a small group of nunataks rising to about on Charcot Island, in the eastern Bellinghausen Sea of Antarctica.

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 ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Antarctic Specially Protected Area
An Antarctic Specially Protected Area (ASPA) is an area on the continent of Antarctica, or on nearby islands, which is protected by scientists and several different international bodies. The protected areas were established in 1961 under the Antarctic Treaty System, which governs all the land and water south of 60 latitude and protects against human development. A permit is required for entry into any ASPA site. The ASPA sites are protected by the governments of Australia, New Zealand, United States, United Kingdom, Chile, France, Argentina, Poland, Russia, Norway, Japan, India, Italy, and Republic of Korea. There are currently 72 sites.

Mountains Of Palmer Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
