Nobby Nunatak
Nobby Nunatak () is a nunatak, 270 m, standing 1 nautical mile (1.9 km) south of Lake Boeckella and 1 nautical mile (1.9 km) east of Mount Flora, at the northeast end of Antarctic Peninsula. This area was first explored by a party under J. Gunnar Andersson of the Swedish Antarctic Expedition, 1901–04. Nobby Nunatak was first charted and named by the Falkland Islands Dependencies Survey (FIDS) in 1945. The name is descriptive. Antonio Moro Refuge Refuge Antonio Moro (), is an Antarctic refuge in Antarctica, located at the Nobby Nunatak on the Tabarin Peninsula in the Trinity Peninsula, administered by the Argentine Army. It was inaugurated on 20 August 1955, renamed Islas Malvinas on 26 August 1971 and rebuilt in 1988. The original name of the refuge paid homage to Antonio Moro, an Italian immigrant who participated in the construction of the San Martín base in 1951 and who built shelters in the Esperanza area in 1954, including the one that bears his name. ...

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past ...

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish Antarctic Expedition
The Swedish Antarctic Expedition of 1901–1903 was a scientific expedition led by Otto Nordenskjöld and Carl Anton Larsen. It was the first Swedish endeavour to Antarctica in the Heroic Age of Antarctic Exploration. Background Otto Nordenskjöld, a Swedish geologist and geographer, organized and led a scientific expedition of the Antarctic Peninsula. The expedition's overall command was placed under the Norwegian Carl Anton Larsen, an experienced Antarctic explorer who served as captain of , and who had previously commanded a whaling reconnaissance mission in 1892–1893. Seven other scientists, including archaeologist Johan Gunnar Andersson, botanist Carl Skottsberg, and zoologist Axel Ohlin, along with 16 officers and men joined them on the voyage. On 16 October 1901, the ''Antarctic'' left the Port of Gothenburg.

Tabarin Peninsula
Tabarin Peninsula () is a peninsula 15 nautical miles (28 km) long and 5 to 12 nautical miles (22 km) wide, lying south of the trough between Hope Bay and Duse Bay and forming the east extremity of Trinity Peninsula in the Antarctic Peninsula. It was discovered and charted by the Swedish Antarctic Expedition, 1901–1904, led by Otto Nordenskjöld and Carl Anton Larsen. It was mapped in 1946 by the Falkland Islands Dependencies Survey (FIDS) and named after Operation Tabarin, the naval code name for the FIDS from 1943 to 1945. Geography The Tabarin Peninsula extends from the northernmost point of the Antarctic Peninsula southwards into the Weddell Sea for about . It is connected to the mainland by an isthmus about wide which lies between Hope Bay to the north and Duse Bay to the south.

Argentine Army
The Argentine Army ( es, Ejército Argentino, EA) is the land force branch of the Armed Forces of the Argentine Republic and the senior military service of Argentina. Under the Argentine Constitution, the president of Argentina is the commander-in-chief of the Armed Forces, exercising his or her command authority through the Minister of Defense. The Army's official foundation date is May 29, 1810 (celebrated in Argentina as the ''Army Day''), four days after the Spanish colonial administration in Buenos Aires was overthrown. The new national army was formed out of several pre-existing colonial militia units and locally manned regiments; most notably the Infantry Regiment "Patricios", which to this date is still an active unit. , the active element of the Argentine Army numbered some 70,600 military personnel. History Several armed expeditions were sent to the Upper Peru (now Bolivia), Paraguay, Uruguay and Chile to fight Spanish forces and secure Argentina's newly ga ...

Trinity Peninsula
Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km (80 mi) to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base. History It was first sighted on 30 January 1820 by Edward Bransfield, Master, Royal Navy, immediately after his charting of the newly discovered South Shetland Islands nearby. In the century following the peninsula's discovery, chartmakers used various names (Trinity Land, Palmer Land, and Land of Louis Philippe) for this portion of it, each name having some historical merit. The recommended name derives from "Trinity Land", given by Bransfield during 1820 in likely recognition of the Corporation of Trinity House, Britain's historical maritime pilotage authority, alth ...

Weddell Sea
The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf. The sea is contained within the two overlapping Antarctic territorial claims of Argentine Antarctica, the British Antarctic Territory, and also resides partially within the Antarctic Chilean Territory. At its widest the sea is around across, and its area is around . Various ice shelves, including the Filchner-Ronne Ice Shelf, fringe the Weddell sea. Some of the ice shelves on the east side of the Antarctic Peninsula, which formerly covered roughly of the Weddell Sea, had completely disappeared by 2002. The Weddell Sea has been d ...

Antarctic Field Camps
Many Antarctic research stations support satellite field camps which are, in general, seasonal camps. The type of field camp can vary – some are permanent structures used during the annual Antarctic summer, whereas others are little more than tents used to support short term activities. Field camps are used for many things, from logistics ( Sky Blu) to dedicated scientific research ( WAIS Divide Field Camp). List of field camps See also * Research stations in Antarctica * Demographics of Antarctica *List of Antarctic expeditions This list of Antarctic expeditions is a chronological list of expeditions involving Antarctica.
