Ambergris Glacier
Ambergris Glacier () is a glacier flowing south-southeast from Mount Sara Teodora between Chintulov Ridge and Valkosel Ridge to join Flask Glacier just west of Fluke Ridge in Aristotle Mountains on the east coast of Graham Land, Antarctica. One of several names in the area that reflect a whaling theme, it was named in 1987 by the United Kingdom Antarctic Place-Names Committee from the substance secreted by the sperm whale and used in perfumery.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern 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 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 measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Flask Glacier
Flask Glacier (), is a gently-sloping glacier, long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica. The lower reaches of this glacier were surveyed and photographed by the Falklands Islands Dependencies Survey (FIDS) in 1947. The entire glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–56, and mapped by the FIDS in 1957. It was named by the UK Antarctic Place-names Committee after the third mate on the ''Pequod'' in Herman Melville's '' Moby-Dick; or, The White Whale''.

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.

Aristotle Mountains is the fan-shaped sequence of ridges spreading east-northeastwards from its summit Madrid Dome (1647 m) on Oscar II Coast in Graham Land on the Antarctic Peninsula. The feature is named after the ancient Greek scientist Aristotle who in his book ''Meteorology'' dated c. 350 BC was the first to conjecture the existence of a landmass in the southern high-latitude region, calling it ''Antarctica''.Aristotle Mountains.

United Kingdom 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 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.

Ambergris
Ambergris ( or , la, ambra grisea, fro, ambre gris), ''ambergrease'', or grey amber is a solid, waxy, flammable substance of a dull grey or blackish colour produced in the digestive system of sperm whales. Freshly produced ambergris has a marine, fecal odor. It acquires a sweet, earthy scent as it ages, commonly likened to the fragrance of Isopropyl alcohol without the vaporous chemical astringency. Ambergris has been highly valued by perfume makers as a fixative that allows the scent to endure much longer, although it has been mostly replaced by synthetic ambroxide. Dogs are attracted to the smell of ambergris and are sometimes used by ambergris searchers. Etymology The word ''ambergris'' comes from the Old French "''ambre gris''" or "grey amber". The word "amber" comes from the same source, but it has been applied almost exclusively to fossilized tree resins from the Baltic region since the late 13th century in Europe. Furthermore, the word "amber" is derived from the Mid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm Whale
The sperm whale or cachalot (''Physeter macrocephalus'') is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus ''Physeter'' and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus ''Kogia''. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales (orcas). Mature males average in length, with the head representing up to one-third of the animal's length. Plunging to , it is the third deep ...
