Mount Estes
Black Island (), in the Ross Archipelago, is immediately west of White Island. It was first named by the ''Discovery'' Expedition (1901–04) because of its lack of snow. The island's northernmost point is named ''Cape Hodgson'', commemorating Thomas Vere Hodgson, one of the oldest members of the ''Discovery'' Expedition. The highest point is Mount Aurora, a principal radio relay point. Mt. Aurora was named between 1958-1959 for the ''Aurora'', one of the ships on Shackleton's Expedition. On the minor peak of Mount Melania is the principal earth-based ground-station for the US Antarctic Program. Black Island is volcanic in origin, consisting of a series of trachytic lava domes and basaltic pyroclastic cones. Potassium–argon dating of Black Island volcanic rocks has given ages ranging from 1.69 to 3.8 million years. There are three main geological formations representing three eruptive sequences on Black Island: Nubian Basalt Formation, Aurora Trachyte Formation, an ...

Ski-Doo
Ski-Doo is a brand name of snowmobile manufactured by Bombardier Recreational Products (originally Bombardier Inc. before the spin-off). The Ski-Doo personal snowmobile brand is so iconic, especially in Canada, that it was listed in 17th place on the CBC's The Greatest Canadian Invention list in 2007. Ski-Doo also has its own range of snowmobile suits. History The first ever Ski-Doo was launched in 1959 as a new invention created by Joseph-Armand Bombardier. The original name was ''Ski-Dog'', but a typographical error in a Bombardier brochure changed the name Ski-Dog to Ski-Doo. The first Ski-Doos found customers with missionaries, Animal trapping, trappers, prospecting, prospectors, land surveyors and others who need to travel in snowy, remote areas. The largest success for the snowmobile came from sport enthusiasts, a market that opened the door to massive production of snowmobiles. This popularity led to ''skidoo'' (sometimes ''ski-doo''), with the derived verb ''skidooing' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territorial Claims In Antarctica
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as China, India, Italy, Pakistan, Russia, South Africa ( SANAE), Ukraine, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom. History Spanish claims According to Argentina and Chile, the Spanish Crown had claims on Antarctica. The ''capitulación'' (governorship) granted to the conquistador Pedro Sánchez de la Hoz in 1539 by the King of Spain, Charles V, explicitly included al ...

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...

Composite Antarctic Gazetteer
The Composite Gazetteer of Antarctica (CGA) of the Scientific Committee on Antarctic Research (SCAR) is the authoritative international gazetteer containing all Antarctic toponyms published in national gazetteers, plus basic information about those names and the relevant geographical features. The Gazetteer includes also parts of the International Hydrographic Organization (IHO) General Bathymetric Chart of the Oceans (GEBCO) gazetteer for under-sea features situated south of 60° south latitude. , the overall content of the CGA amounts to 37,893 geographic names for 19,803 features including some 500 features with two or more entirely different names, contributed by the following sources: {, class="wikitable sortable" !

List Of Volcanoes In Antarctica ...
This is a list of volcanoes in Antarctica. Table A 2017 study claimed to have found 138 volcanoes, of which 91 were previously unknown. Some volcanoes are entirely under the ice sheet. Unconfirmed volcanoes are not included in the table below. See also * Geology of Antarctica * Lists of volcanoes References Bibliography * Volcano World Web site {{Antarctica Antarctica * Volcanoes A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Minna Bluff
Minna Bluff is a rocky promontory at the eastern end of a volcanic Antarctic peninsula projecting deep into the Ross Ice Shelf at . It forms a long, narrow arm which culminates in a south-pointing hook feature (Minna Hook), and is the subject of research into Antarctic cryosphere history, funded by the National Science Foundation, Office of Polar Programs. The bluff is mentioned repeatedly in the history of Antarctic exploration. It was first sighted in June 1902, during Captain Robert Falcon Scott's ''Discovery'' Expedition, 1901–04. It was thereafter recognised as a key landmark and location for vital supply depots for southern journeys towards the South Pole. Originally identified simply as "the Bluff", it was later named by Scott after the wife of Royal Geographical Society former president Sir Clements Markham. Every expedition that followed Scott on this route after his pioneering journey (including Ernest Shackleton in 1908, Scott himself in 1911 and Shackleton's ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...
