Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Snowshoe Glacier
Neny Fjord is a fjord which is long in an east–west direction and wide, between Red Rock Ridge and Roman Four Promontory on the west coast of Graham Land, Antarctica. Geography *Mount Dudley History This coast was first explored in 1909 by Jean-Baptiste Charcot who, it appears, gave this name to a feature somewhat north of the bay described. The British Graham Land Expedition (BGLE) made a detailed survey of this area in 1936–1937, and in correlating their work with that of Charcot applied the name Neny Fjord to the bay between Red Rock Ridge and Roman Four Promontory. The name has become established in this latter position through international acceptance and use.

Red Rock Ridge (33415136978)
Red Rock Ridge or Morro Roca Roja or Promontorio Roca Roja is a conspicuous reddish-colored ridge or promontory which rises to 690 m and projects from the west coast of Graham Land between Neny Fjord and Rymill Bay. Red Rock Ridge is located at and has an elevation of 690 m. Red Rock Ridge was surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, who so named it because of its color. Further surveys in 1948 by the Falkland Islands Dependencies Survey (FIDS) have identified this ridge as the feature first sighted in 1909 and named "Île Pavie" or "Cap Pavie" by the French Antarctic Expedition under Jean-Baptiste Charcot, but the name Red Rock Ridge is now too firmly established to alter. The name Pavie Ridge Pavie Ridge or Cap Pavie or Île Pavie is a rocky ridge located at in Antarctica which rises over 500 m. It extends south and west from Martin Glacier to Moraine Cove, and forms the southeastern limit of the Bertrand Ice Piedmo ...

Sextant
A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle, the altitude, is known as ''sighting'' or ''shooting'' the object, or ''taking a sight''. The angle, and the time when it was measured, can be used to calculate a position line on a nautical or aeronautical chart—for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) to estimate latitude (with sight reduction). Sighting the height of a landmark can give a measure of ''distance off'' and, held horizontally, a sextant can measure angles between objects for a position on a chart. A sextant can also be used to measure the lunar distance between the moon and another celestial object (such as a star or planet) in order to determine Greenwich Mean Time and hence ...

Quadrant (instrument)
A quadrant is an instrument used to measure angles up to 90°. Different versions of this instrument could be used to calculate various readings, such as longitude, latitude, and time of day. Its earliest recorded usage was in ancient India in Rigvedic times by Rishi Atri to observe a solar eclipse. It was then proposed by Ptolemy as a better kind of astrolabe. Several different variations of the instrument were later produced by medieval Muslim astronomers. Mural quadrants were important astronomical instruments in 18th-century European observatories, establishing a use for positional astronomy. Etymology The term ''quadrant'', meaning one fourth, refers to the fact that early versions of the instrument were derived from astrolabes. The quadrant condensed the workings of the astrolabe into an area one fourth the size of the astrolabe face; it was essentially a quarter of an astrolabe. History During Rigvedic times in ancient India, quadrants called 'Tureeyam's were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Godfrey (inventor)
Thomas Godfrey (January 10, 1704 – December 1749) was a glazier and self-taught mathematician and astronomer in the Pennsylvania Colony, who invented the octant in 1730. A similar octant was also independently invented about the same time by John Hadley in London with Hadley receiving the greater share of the credit for development. He published almanacs and contributed essays on mathematics, astronomy and general topics to the ''Pennsylvania Gazette'' and '' Pennsylvania Journal''. He assisted the Welsh surveyor Lewis Evans in conducting astronomical observations to correct the longitude of Philadelphia on maps published by Evans. He was friends with Benjamin Franklin and a founding member of the Junto club, which was the precursor of the American Philosophical Society. He served as a director of the Library Company of Philadelphia and was a member of American Philosophical Society with the title "mathematician". Early life Godfrey was born January 10, 1704, to Joseph an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Hadley
John Hadley (16 April 1682 – 14 February 1744) was an English mathematician, and laid claim to the invention of the octant, two years after Thomas Godfrey claimed the same. Biography He was born in Bloomsbury, London the eldest son of George Hadley of Osidge, East Barnet, Hertfordshire and his wife Katherine FitzJames. His younger brother George Hadley became a noted meteorologist. In 1717 John became a member (and later vice-president) of the Royal Society of London. In 1729 he inherited his father's East Barnet estate. He died in East Barnet in 1744 and is buried in the local churchyard with other members of his family. He had married Elizabeth, daughter of Thomas Hodges, FRS (former Attorney General of Barbados) and had one child, a son and heir John, born in 1738. Work In 1730 Hadley invented the reflecting octant, which could be used to measure the altitude of the sun or other celestial objects above the horizon at sea.

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Finn Ronne
Finn Ronne (December 20, 1899 – January 12, 1980) was a Norwegian-born U.S. citizen and Antarctic explorer. Background Finn Ronne was born in Horten, in Vestfold county, Norway. His father, Martin Rønne (1861–1932), was a polar explorer who served in Roald Amundsen's successful expedition to the South Pole. Ronne received his education in engineering at Horten Technical College. In 1923 Finn Ronne immigrated to the U.S. and gained citizenship in 1929. After working at Westinghouse Electric Corporation for some years, he took part in two of Richard E. Byrd's expeditions to the South Pole, and in 1939 Ronne served as Byrd's executive officer helping discover one thousand miles of new coastline. After serving several years in the United States Navy, gaining the rank of captain, Ronne returned to Antarctica in the 1940s, with support of the American Geographical Society as the leader of the Ronne Antarctic Research Expedition.
