Cassini Glacier
Cassini Glacier is a steep glacier between Goat Mountain and Bonne Glacier, descending northwest from Hobbs Ridge into Blue Glacier, in Victoria Land, Antarctica.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Bonne Glacier
Bonne Glacier () is a steep glacier west-southwest of Hobbs Peak, descending northwest from Hobbs Ridge into Blue Glacier, in Victoria Land. The name is one of a group in the area associated with surveying applied in 1993 by the New Zealand Geographic Board. It was named after the Bonne map projection, a derivative conical projection In cartography, map projection is the term used to describe a broad set of transformations employed to represent the two-dimensional curved surface of a globe on a plane. In a map projection, coordinates, often expressed as latitude and longitu ..., in which the parallels are spaced at true distances along meridians which are plotted as curves.

Hobbs Ridge
Hobbs Ridge () is a prominent arc-shaped ridge which circumscribes Hobbs Glacier to the north and northwest and forms the divide with the lower part of Blue Glacier, on the Scott Coast of Victoria Land Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau.

Blue Glacier (Antarctica)
Blue Glacier is a large glacier which flows into Bowers Piedmont Glacier about south of New Harbour, in Victoria Land, Antarctica. Robbins Hill is the East-most rock unit on the north side of the terminus of the glacier. It was discovered by the British National Antarctic Expedition under Robert Falcon Scott Captain Robert Falcon Scott, , (6 June 1868 – c. 29 March 1912) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the ''Discovery'' expedition of 1901–1904 and the ill-fated ''Terra Nov ..., 1901–04, who gave it this name because of its clear blue ice at the time of discovery.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand Geographic Board
The New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB) was established by the New Zealand Geographic Board Act 1946, which has since been replaced by the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008. Although an independent institution, it is responsible to the Minister for Land Information. The board has authority over geographical and hydrographic names within New Zealand and its territorial waters. This includes the naming of small urban settlements, localities, mountains, lakes, rivers, waterfalls, harbours and natural features and may include researching local Māori names. It has named many geographical features in the Ross Sea region of Antarctica. It has no authority to alter street names (a local body responsibility) or the name of any country. The NZGB secretariat is part of Toitū Te Whenua Land Information New Zealand (LINZ) and provides the board with administrative and research assistance and advice. The New Zealand Geograph ...

Cassini Projection
The Cassini projection (also sometimes known as the Cassini–Soldner projection or Soldner projection) is a map projection described by César-François Cassini de Thury in 1745. It is the transverse aspect of the equirectangular projection, in that the globe is first rotated so the central meridian becomes the "equator", and then the normal equirectangular projection is applied. Considering the earth as a sphere, the projection is composed of the operations: :x = \arcsin(\cos \varphi \sin \lambda) \qquad y = \arctan\left(\frac\right). where ''λ'' is the longitude from the central meridian and ''φ'' is the latitude. When programming these equations, the inverse tangent function used is actually the atan2 function, with the first argument sin ''φ'' and the second . The reverse operation is composed of the operations: :\varphi = \arcsin(\sin y \cos x) \qquad \lambda = \operatorname(\tan x, \cos y). In practice, the projection has always been applied to models of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
