Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society.

King George Island (South Shetland Islands)
King George Island (Argentinian Spanish: Isla 25 de Mayo, Chilean Spanish: Isla Rey Jorge, Russian: Ватерло́о Vaterloo) is the largest of the South Shetland Islands, lying off the coast of Antarctica in the Southern Ocean. The island was named after King George III. Geography King George island has three major bays, Maxwell Bay, Admiralty Bay, and King George Bay. Admiralty Bay contains three fjords, and is protected as an Antarctic Specially Managed Area under the Protocol on Environmental Protection to the Antarctic Treaty. History The island was first claimed for Britain on 16 October 1819, formally annexed by Britain as part of the Falkland Islands Dependencies in 1908, and now as part of the separate British Antarctic Territory. The Island was claimed by Chile in 1940, as part of the Chilean Antarctic Territory. It was also claimed by Argentina in 1943, now as part of Argentine Antarctica, called by the Argentines ''Isla Veinticinco de Mayo'' (25 May) in ho ...

Barbeau Peak
__NOTOC__ Barbeau Peak is a mountain in Qikiqtaaluk, Nunavut, Canada. Located on Ellesmere Island within Quttinirpaaq National Park, it is the highest mountain in Nunavut and the Canadian Arctic. The mountain was named in 1969 after Marius Barbeau, a Canadian anthropologist whose research into First Nations and Inuit cultures gained him international acclaim. Barbeau Peak is characterized by deep and long crevasses, razor thin ridges and highly variable and volatile weather. Barbeau Peak is the highest mountain within the British Empire Range as well as the Arctic Cordillera, as well as in all of eastern North America. Barbeau Peak was first climbed on 7 June 1967 by British geologist/glaciologist Geoffrey Hattersley-Smith as part of a joint Defence Research Board/Royal Air Force field party. The party both named the peak and determined its height. The second ascent was by an eight-man American team in June 1982 (Errington, Trafton AAC 1983) via the north ridge. Subsequent ascen ...

Tanquary Fiord
Tanquary Fiord is a fjord on the north coast of the Arctic Archipelago's Ellesmere Island, Nunavut, Canada. It is located in the Quttinirpaaq National Park and extends in a north-westerly direction from Greely Fiord. History Radiocarbon dating methods suggest that between 10,000 and 4,100 BP, deglaciation occurred, followed by a period of glacial readvance and the formation of ice shelves until 2,400 BP. Until 1,400 BP, a period of glacial retreat occurred, and since then glacial readvance and nearby ice rises have marked the area. Radiocarbon analysis of charcoal undertaken by the Geological Survey of Canada has shown that Inuit were present at Tanquary Fiord around 1070 BP at the latest. Geography The head of the Tanquary Fiord is the convergence point of four river valleys, three of which end in a floodplain and one in a river delta. Carbon dating findings show that the fjord was free of glacial ice approximately 6,500 years ago. In the past 40 years, the terminal ...

Ward Hunt Island
Ward Hunt Island is a small, uninhabited island in the Arctic Ocean, located off the north coast of Ellesmere Island near the Ward Hunt Ice Shelf. The island is located just from the geographical North Pole. The northern cape of Ward Hunt Island is one of the northernmost elements of land in Canada. Only a stretch of northern coast of Ellesmere Island around Cape Columbia is more northerly. The island is long, east to west, and wide. The first known sighting was in 1876 by Pelham Aldrich, a lieutenant with the George Nares expedition, and named for George Ward Hunt, who was First Lord of the Admiralty at the time (1874–1877). Today, the Island is part of the Quttinirpaaq National Park. History and research Due to its location, the island has been used as the starting point for a number of attempts to reach the North Pole, e.g. Ralph Plaisted and others. During the International Geophysical Year of 1957–58, it was briefly used as a meteorological station. In 1959 the Cana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Hazen
Lake Hazen is a freshwater lake in the northern part of Ellesmere Island, Nunavut, Canada, north of the Arctic Circle. It is the largest lake north of the Arctic Circle by volume. By surface area it is third largest, after Lake Taymyr in Russia and Lake Inari in Finland. The area around the lake is a thermal oasis within a polar desert, with summer temperatures up to . The lake itself is covered by ice about ten months a year. It is fed by glaciers (most importantly Henrietta Nesmith and the Gilmour Glaciers) from the surrounding Eureka Uplands—Palaeozoic rocks north of the lake, rising up to above sea level—and drained by long Ruggles River, which flows into Chandler Fjord on the northern east coast of Ellesmere Land. The lake is flanked by the Arctic Cordillera. The lake is long and up to wide, with an area of .Mark Nuttal: ''Encyclopedia of the Artctic''.

International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it covered th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nunavut
Nunavut ( , ; iu, ᓄᓇᕗᑦ , ; ) is the largest and northernmost Provinces and territories of Canada#Territories, territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the ''Nunavut Act'' and the ''Nunavut Land Claims Agreement, Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for independent government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the territorial evolution of Canada, first major change to Canada's political map in half a century since the province of Newfoundland and Labrador, Newfoundland was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the list of the largest country subdivisions by area, fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland).
