Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

South Shetland Islands
The South Shetland Islands are a group of List of Antarctic and subantarctic islands, Antarctic islands located in the Drake Passage with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty System, Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories. According to British government language on the topic, "the whole of Antarctica is protected in the interests of peace and science." The islands have been claimed by three countries, beginning with the United Kingdom since 1908 (since 1962 as part of the equally unrecognized British Antarctic Territory). The islands are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province), and by Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province, Argentina, Tierra del Fuego Province). Several countries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Treaty System
The Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, designating the continent as a scientific preserve, establishing freedom of scientific investigation, and banning Military activity in the Antarctic, military activity; for the purposes of the treaty system, Antarctica is defined as all the land and ice shelf, ice shelves south of 60th parallel south, 60°S latitude. Since September 2004, the Antarctic Treaty Secretariat, which implements the treaty system, is headquartered in Buenos Aires, Argentina. The main treaty was opened for signature on 1 December 1959, and officially coming into force, entered into force on 23 June 1961. The original signatories were the 12 countries active in Antarctica during the International Geophysical Year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seal Hunting
Seal hunting, or sealing, is the personal or commercial hunting of Pinniped, seals. Seal hunting is currently practiced in nine countries: Canada, Denmark (in self-governing Greenland only), Russia, the United States (above the Arctic Circle in Alaska), Namibia, Estonia, Norway, Finland and Sweden. Most of the world's seal hunting takes place in Canada and Greenland. The Canadian Fisheries and Oceans Canada, Department of Fisheries and Oceans (DFO) regulates the seal hunt in Canada. It sets quotas (total allowable catch – TAC), monitors the hunt, studies the seal population, works with the Canadian Sealers' Association to train sealers on new regulations, and promotes sealing through its website and spokespeople. The DFO set harvest quotas of over 90,000 seals in 2007; 275,000 in 2008; 280,000 in 2009; and 330,000 in 2010. The actual kills in recent years have been less than the quotas: 82,800 in 2007; 217,800 in 2008; 72,400 in 2009; and 67,000 in 2010. In 2007, Norway repo ...

Jacques Besson
Jacques Besson (1540?–1573) was a French Protestant inventor, mathematician, and philosopher, chiefly remembered for his popular treatise on machines ''Theatrum Instrumentorum'' (1571–1572), which saw many reprints in different languages. Life Little information has survived about Besson's early life; he described himself as being from Colombières, part of Escarton de Oulx, now in Cesana Torinese, Italy. He was most likely born around 1540. In the early 1550s he is recorded as teaching mathematics in Paris, following which the next account of him dates from April 1557, when he is recorded in the minutes of the town council of Lausanne, Switzerland, as being paid for models of pumps and fountains. In 1559 he published his first treatise in Zurich, the ''De absoluta ratione extrahendi olea et aquas e medicamentis simplicibus'' (on the complete doctrine of extracting oils and waters from simple drugs), featuring an introduction by Conrad Gesner. That same year he moved to Genev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmolabe
The cosmolabe was an ancient astronomical instrument resembling the astrolabe, formerly used for measuring the angles between heavenly bodies. It is also called pantacosm. Jacques Besson also uses this name, or universal instrument, for his invention described in ''Le cosmolabe'' (1566), which could be used for astrometry, cartography, navigation, and surveying Surveying or land surveying is the technique, profession, art, and science of determining the land, terrestrial Plane (mathematics), two-dimensional or Three-dimensional space#In Euclidean geometry, three-dimensional positions of Point (geom .... The Cosmolabe is a comprehensive and versatile astronomical instrument designed to perform a wide range of observations and calculations. It was created to serve as a universal tool, capable of replacing several different instruments used in astronomy, geometry, and navigation.

Geodesy
Geodesy or geodetics is the science of measuring and representing the Figure of the Earth, geometry, Gravity of Earth, gravity, and Earth's rotation, spatial orientation of the Earth in Relative change, temporally varying Three-dimensional space, 3D. It is called planetary geodesy when studying other astronomical body, astronomical bodies, such as planets or Natural satellite, circumplanetary systems. Geodynamics, Geodynamical phenomena, including crust (geology), crustal motion, tides, and polar motion, can be studied by designing global and national Geodetic control network, control networks, applying space geodesy and terrestrial geodetic techniques, and relying on Geodetic datum, datums and coordinate systems. Geodetic job titles include geodesist and geodetic surveyor. History Geodesy began in pre-scientific Classical antiquity, antiquity, so the very word geodesy comes from the Ancient Greek word or ''geodaisia'' (literally, "division of Earth").

Smilets Point
Smilets Point (, ‘Nos Smilets’ \'nos smi-'lets\) is the rocky point on the southwest side of the entrance to Hall Cove, at the northeast end of Lambreva Beach, projecting 500 m north-northwestwards from the northwest coast of Nelson Island in the South Shetland Islands, Antarctica. The area was visited by early 19th century sealers. The point is named after Czar Smilets of Bulgaria, 1292–1298.

Withem Island
Withem Island is an island lying off the northwest side of Nelson Island in the South Shetland Islands. It is situated 1.75 km north of Retamales Point and 1.73 km west-southwest of Kondor Island. The feature was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1961 after Nicholas Withem, master of the American sealing vessel Governor Brooks from Salem, MA, who visited the South Shetland Islands in 1820–21. Originally proposed and approved as ''Withen Island,'' the name was amended in 1990 to agree with the correct spelling of the personal name.
