General Belgrano II
Belgrano II Base ( es, Base Belgrano II) is a permanent, all year-round Argentine Antarctic base and scientific research station named after General Manuel Belgrano, one of the Libertadores and the creator of the Argentine Flag. It is located on Bertrab Nunatak on the Confín Coast, Coats Land. it is Argentina's southernmost permanent base, the world's third furthest south permanent base, and the world's southernmost base built on solid rock, which makes it particularly suited for geological research. Belgrano II is one of 13 research stations in Antarctica operated by Argentina. History In 1955, then Brigade General Hernán Pujato founded the first Belgrano Base ( Belgrano I), which remained for years as Argentina's southernmost settlement. After a continuous activity for 25 years, Belgrano I was closed due to the fast deterioration of the ice barrier it was sitting on; new, often hidden cracks and crevices endangered the on-duty personnel and material.

Provinces Of Argentina
Argentina is subdivided into twenty-three federated states called provinces ( es, provincias, singular ''provincia'') and one called the autonomous city (''ciudad autónoma'') of Buenos Aires, which is the federal capital of the republic ( es, Capital Federal, links=no) as decided by the National Congress of Argentina, Argentine Congress. The provinces and the capital have their own constitutions, and exist under a federalism, federal system. History During the Argentine War of Independence, War of Independence the main cities and their surrounding countrysides became provinces though the intervention of their Cabildo (council), ''cabildos''. The Anarchy of the Year XX completed this process, shaping the original thirteen provinces. Jujuy Province, Jujuy seceded from Salta Province, Salta in 1834, and the thirteen provinces became fourteen. After seceding for a decade, Buenos Aires Province accepted the 1853 Constitution of Argentina in 1861, and its capital city was made ...

Brigade General
Brigadier general or Brigade general is a military rank used in many countries. It is the lowest ranking general officer in some countries. The rank is usually above a colonel, and below a major general or divisional general. When appointed to a field command, a brigadier general is typically in command of a brigade consisting of around 4,000 troops (four battalions). Variants Brigadier general Brigadier general (Brig. Gen.) is a military rank used in many countries. It is the lowest ranking general officer in some countries, usually sitting between the ranks of colonel and major general. When appointed to a field command, a brigadier general is typically in command of a brigade consisting of around 4,000 troops (four battalions). In some countries, this rank is given the name of ''brigadier'', which is usually equivalent to ''brigadier general'' in the armies of nations that use the rank.

ARA Almirante Irízar (Q-5)
ARA ''Almirante Irízar'' is a large icebreaker of the Argentine Navy. She was ordered from a shipyard in Finland in 1975. A fire broke out in her auxiliary generator compartment in 2007, putting her out of commission until April 2017. Background The ship was named after Julián Irízar. In 1903, when he held the rank of Lieutenant, he commanded the Argentine corvette during a successful mission to rescue the Swedish Antarctic Expedition of Professor Otto Nordenskjöld, after the expedition had been trapped by the Antarctic winter. The vessel was built at the Wärtsilä Helsinki Shipyard in Finland, under a contract signed in 1975 between the Argentine Navy and the shipyard. ''Irízar'' was launched in February 1978 and was formally commissioned on December that year, arriving in Argentina on 23 March 1979. She replaced the elderly icebreaker , which was then retired from active service. ''Almirante Irízar''s peacetime missions include annual campaigns to resupply and r ...

Airdrop
An airdrop is a type of airlift in which items including weapons, equipment, humanitarian aid or leaflets are delivered by military or civilian aircraft without their landing. Developed during World War II to resupply otherwise inaccessible troops, themselves often airborne forces, airdrops can also refer to the airborne assault itself. History Early airdrops were conducted by dropping or pushing padded bundles from aircraft. Later, small crates fitted with parachutes were pushed out of aircraft side cargo doors. Later, cargo aircraft were designed with rear access ramps, lowerable in flight, that allowed large platforms to be rolled out the back. As aircraft grew larger, the U.S. Air Force and Army developed ''low-level extraction'', allowing vehicles like light tanks, armored personnel carriers and other large supplies to be delivered. Propaganda leaflets are another commonly airdropped item. Airdrops evolved to include massive bombs as payload. The 15,000-pound (6,800&n ...

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Iceberg
An iceberg is a piece of freshwater ice more than 15 m long that has broken off a glacier or an ice shelf and is floating freely in open (salt) water. Smaller chunks of floating glacially-derived ice are called "growlers" or "bergy bits". The sinking of the ''Titanic'' in 1912 led to the formation of the International Ice Patrol in 1914. Much of an iceberg is below the surface, which led to the expression "tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard. Icebergs vary considerably in size and shape. Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs. The largest iceberg in recent history (2000), named B-15, measured nearly 300 km × 40 km. The largest iceberg on record was an Antarctic tabular iceberg of over [] sighted west of Scott Island, in the South Pacific Ocean, by the USS Glacier ...

ARA General San Martín
ARA ''General San Martín'' was the first icebreaker of the Argentine Navy. She participated in several Antarctic campaigns of Argentina between 1954 and 1982. She received the name of José de San Martín. For twenty-five years she drew his sea routes in the southern seas, which enabled the summer and winter campaigns. She carried out numerous research and relief assistance missions to ships, navigators and expeditionaries; she facilitated the foundation of refuges and Antarctic bases, the replacement of the endowments, the exploration of the Weddell Sea and the accomplishment of oceanographic tasks, hydrographic and meteorological investigations in Argentine Antarctica.

Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull to ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

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 can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moltke Nunataks
The Moltke Nunataks () are a chain of north–south trending nunataks close to the northeastern end of the Filchner Ice Shelf, Antarctica. One nunatak was first roughly mapped and named "Moltke Nunatak" by the Second German Antarctic Expedition of 1911–12 under Wilhelm Filchner Wilhelm Filchner (13 September 1877 – 7 May 1957) was a German army officer, scientist and explorer. He conducted several surveys and scientific investigations in China, Tibet and surrounding regions, and led the Second German Antarctic Expeditio .... He named it for General Helmuth von Moltke, Chief of the German General Staff and Secretary of State for Home Affairs. Surveys during the mid-1950s by British, Argentine and United States expeditions indicate that a group of four or five nunataks exist in the area.
