Kuparuk River
The Kuparuk River ( Iñupiaq: ''Kuukpaaġruk'') is a river in Alaska's North Slope that enters a bay on the Beaufort Sea between Beechey Point and Prudhoe Bay. The north-flowing river is about long, and its delta is about wide. Its Eskimo name appeared on a map drawn in 1901 by a prospector who spelled it ''Koopowra'', which he translated as ''Big River''. ''Kuukpaaġruk'' can be translated to a "smaller version of a big river". Kuparuk Mound, a pingo about southeast of Beechey Point, is named after the river. Arctic explorer Ernest de Koven Leffingwell named the mound, which he used as a triangulation station in 1911. The Kuparuk River oil field, the second largest oil field in North America, is centered about west of Prudhoe Bay. Discovered in 1969, it covers about .

River Delta
A river delta is a landform shaped like a triangle, created by deposition (geology), deposition of sediment that is carried by a river and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. It is so named because its triangle shape resembles the Greek letter Delta. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment, and receiving basin processes that redistribute, sequester, and export that sediment. The size, geometry, and location of the receiving basin also plays an important role in delta evolution. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide Coast, coastline defense and can impact drinking water supply. They are also Ecology, ecologically important, with different species' assemblages ...

Kuparuk River Oil Field
The Kuparuk River Oil Field, or Kuparuk, located in North Slope Borough, Alaska, United States, is the second largest oil field in North America by area. It produces approximately of oil and is estimated to have of recoverable oil reserves. It is named for the Kuparuk River. Production History Kuparuk was discovered by Sinclair Oil in April 1969 at the Ugnu Number 1 well, named for the nearby Ugnuravik River. Oil was found in the Kuparuk sandstone on the Colville structure. Production was first announced by ARCO in 1979 and planned to start in 1982. Production actually began December 13, 1981, on five small gravel drilling pads. Production was expected to peak in 1986 at , but did not peak until 1992 at from 371 wells. In December 2002, the production averaged from 448 wells, but by September 2016 the average declined to . For the first six months of 2017 production averaged with a water cut of 87.4 percent. During the first half of 2019 the pool averaged with a water c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangulation Station
A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity. The nomenclature varies regionally: they are generally known as trigonometrical stations or triangulation stations in North America, trig points in the United Kingdom, trig pillars in Ireland, trig stations or trig points in Australia and New Zealand, and trig beacons in South Africa. Use The station is usually set up by a government with known coordinates and elevation published. Many stations are located on hilltops for the purposes of visibility. A graven metal plate on the top of a pillar may provide a mounting point for a theodolite or reflector, often using some form of kinematic coupling to ensure reproducible positioning. Trigonometrical stations are grouped together to form a network of triangulation. Positions of all land boundaries, roads, railways, bridges and other ...

Ernest De Koven Leffingwell
Ernest de Koven Leffingwell (January 13, 1875January 27, 1971) was an arctic explorer, geologist and Spanish–American War veteran. During the period from 1906 to 1914, Leffingwell spent nine summers and six winters on the Arctic coast of Alaska, making 31 trips by dog sled or small boats. He created the first accurate map of a large part of the Alaskan arctic coastline. He was the first to scientifically describe permafrost and to pose theories about permafrost which have largely proven true. He accurately identified the oil potential of the North Slope region of Alaska. Biography Ernest de Koven Leffingwell was born January 13, 1875, in Knoxville, Illinois, to Charles and Elizabeth (née Francis) Leffingwell. He attended the grammar school at Racine College, then attended Trinity College, Hartford, Connecticut, where he was captain of the track team his senior year, graduated with the AB degree in 1895 and was awarded a MA in 1900. He studied physics and geology at the Univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pingo
Pingos are intrapermafrost ice-cored hills, high and in diameter. They are typically conical in shape and grow and persist only in permafrost environments, such as the Arctic and subarctic. A pingo is a periglacial landform, which is defined as a non-glacial landform or process linked to colder climates. It is estimated that there are more than 11,000 pingos on Earth. The Tuktoyaktuk peninsula area has the greatest concentration of pingos in the world with a total of 1,350 pingos. There is currently remarkably limited data on pingos. History In 1825, John Franklin made the earliest description of a pingo when he climbed a small pingo on Ellice Island in the Mackenzie Delta. However, it was in 1938 that the term ''pingo'' was first borrowed from the Inuvialuit by the Arctic botanist Alf Erling Porsild in his paper on Earth mounds of the western Arctic coast of Canada and Alaska. Porsild Pingo in Tuktoyaktuk is named in his honour. The term pingos, which in Inuvialuktun m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prospecting
Prospecting is the first stage of the geological analysis (followed by exploration) of a territory. It is the search for minerals, fossils, precious metals, or mineral specimens. It is also known as fossicking. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct observation can then be focused on this area. In some areas a prospector must also make claims, meaning they must erect posts with the appropriate placards on all four corners of a desired land they wish to prospect and register this claim before they may take samples. In other areas publicly held lands are open to prospecting without staking a mining claim. Historical methods The traditional methods of prospecting involved combi ...

Eskimo Language
The Eskaleut (), Eskimo–Aleut or Inuit–Yupik–Unangan languages are a language family native to the northern portions of the North American continent and a small part of northeastern Asia. Languages in the family are indigenous to parts of what are now the United States (Alaska); Canada ( Inuit Nunangat including Nunavut, Northwest Territories (principally in the Inuvialuit Settlement Region), northern Quebec ( Nunavik), and northern Labrador (Nunatsiavut); Greenland; and the Russian Far East (Chukchi Peninsula). The language family is also known as ''Eskaleutian'', ''Eskaleutic'' or ''Inuit–Yupik–Unangan''. The Eskaleut language family is divided into two branches: the Eskimoan languages and the Aleut language. The Aleut branch consists of a single language, Aleut, spoken in the Aleutian Islands and the Pribilof Islands. Aleut is divided into several dialects. The Eskimoan languages are divided into two branches: the Yupik languages, spoken in western and southwestern A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prudhoe Bay, Alaska
Prudhoe Bay is a census-designated place (CDP) located in North Slope Borough in the U.S. state of Alaska. As of the 2010 census, the population of the CDP was 2,174 people, up from just five residents in the 2000 census; however, at any given time, several thousand transient workers support the Prudhoe Bay oil field. The airport, lodging and general store are located in Deadhorse, and the rigs and processing facilities are located on scattered gravel pads laid atop the tundra. It is only during winter that the surface is hard enough to support heavy equipment, and new construction happens at that time. Prudhoe Bay is the unofficial northern terminus of the Pan-American Highway. As the bay itself is still 10 miles further north through a security checkpoint, open water is not visible from the highway. A few tourists, arriving by bus after a two-day ride up the Dalton Highway from Fairbanks, come to see the tundra, the Arctic Ocean and the midnight sun, staying in lodgings ass ...

North Slope, Alaska
The Alaska North Slope ( Iñupiaq: ''Siḷaliñiq'') is the region of the U.S. state of Alaska located on the northern slope of the Brooks Range along the coast of two marginal seas of the Arctic Ocean, the Chukchi Sea being on the western side of Point Barrow, and the Beaufort Sea on the eastern. Petroleum resources The Alaska North Slope region includes the National Petroleum Reserve–Alaska, with the bulk of Alaska's known petroleum until the Prudhoe Bay Oil Field was discovered in 1968, followed by the Kuparuk River oil field in 1969. The region also includes the Arctic National Wildlife Refuge, which itself has been the subject of controversy surrounding the possibility of petroleum drilling within its boundaries. The petroleum extracted from the region is transferred south by means of the Trans-Alaska Pipeline System to Valdez on the Pacific Ocean. Under the North Slope is an ancient seabed, which is the source of the oil. Within the North Slope, there is a geologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
