Summit Week 1
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary. ...

List Of Research Stations In The Arctic
A number of governments maintain permanent research stations in the Arctic. Also known as Arctic bases, polar stations or ice stations, these bases are widely distributed across the northern polar region of Earth. Historically few research stations have been permanent. Most of them were temporary, being abandoned after the completion of the project or owing to lack of funding to continue the research. Some of these were military or intelligence stations (listening posts) created as a result of the proximity of the U.S. and Soviet Union to each other's landmass across the polar region. Ice stations are constructed on land or on ice that rests on land, while others are drifting ice stations built on the sea ice of the high latitudes of the Arctic Ocean.

Kenn Borek Air
Kenn Borek Air is an airline based in Calgary, Alberta, Canada. It operates regional passenger and cargo services, contract operations in the Arctic and Antarctic and aircraft leasing. Its main base is at Calgary International Airport. It charters aircraft for scientific expeditions, oil exploration, etc., and operates air ambulance services. History The airline was established in 1966 as Vic Turner Ltd which operated a single de Havilland Canada DHC-6 Twin Otter providing air support for oil exploration activities in the Canadian Arctic. Renamed Kenn Borek Air after being purchased by Borek Construction in 1971, the company acquired the Aklavik Flying Services which was founded in April 1947 by Michael Zubko operating a single Aeronca Champion at that time. In 1975 Kenn Borek acquired Kenting Atlas Aviation which was established in 1947 as Atlas Aviation then renamed to Kenting Aviation in 1972. The company has been operating in Antarctica since 1985. On 26 April 2001, Kenn B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Otter
The de Havilland Canada DHC-6 Twin Otter is a Canadian STOL (Short Takeoff and Landing) utility aircraft developed by de Havilland Canada, which produced the aircraft from 1965 to 1988; Viking Air purchased the type certificate, then restarted production in 2008 before re-adopting the DHC name in 2022. The aircraft's fixed tricycle undercarriage, STOL capabilities, twin turboprop engines and high rate of climb have made it a successful commuter airliner, typically seating 18-20 passengers, as well as a cargo and medical evacuation aircraft. In addition, the Twin Otter has been popular with commercial skydiving operations, and is used by the United States Army Parachute Team and the United States Air Force's 98th Flying Training Squadron. Design and development Development of the aircraft began in 1964, with the first flight on May 20, 1965. A twin-engine replacement for the single-engine DHC-3 Otter retaining DHC's STOL qualities, its design features included double-slotte ...

LC-130 Hercules
The Lockheed LC-130 is a ski-equipped United States Air Force variant of the C-130 Hercules used in the Arctic and Antarctic. Ten are currently in service with the 109th Airlift Wing of the New York Air National Guard. Design and development The LC-130 started as a prototype model developed by modifying a ''C-130A'' with skis in 1956. After testing in 1957, 12 additional C-130A models were modified with skis and hydraulics under the designation of ''C-130D''. In 1959 the first four factory equipped, ski-based Hercules were produced under the Navy designation of UV-1L. These C-130s are USAF C-130B models. Later in the program the designation was changed from UV-1L to C-130BL. This designation was again later changed to LC-130F when aircraft nomenclature was standardized for all services by the U. S. Defense Department in 1962. These four aircraft were bought by the Navy Department to support the Navy's Antarctic expedition that was ongoing at the time. The Navy also bought one ...

Kangerlussuaq Airport
Kangerlussuaq Airport ( kl, Mittarfik Kangerlussuaq, da, Søndre Strømfjord Lufthavn) is an airport in Kangerlussuaq, a settlement in the Qeqqata municipality in central-western Greenland. Alongside Narsarsuaq Airport, it is one of only two civilian airports in Greenland large enough to handle large airliners. It is located away from the coast and hence less prone to fog and wind in comparison with other airports in Greenland. Kangerlussuaq Airport is the international hub for Air Greenland. The Kangerlussuaq area has very few inhabitants (around 500), so few passengers have their origin or destination here; most passengers change planes. History The first airport was built here during the US occupation in 1941 under the name of Bluie West-8, later renamed Sondrestromfjord Air Base and Sondrestrom Air Base. In the mid 1950s, transatlantic civilian flights began using the air base for refueling. In 1956, Scandinavian Airlines (SAS) was flying "Polar route" service with thre ...

Danish Meteorological Institute
The Danish Meteorological Institute (DMI; da, Danmarks Meteorologiske Institut) is the official Danish meteorological institute, administrated by the Ministry of Energy, Utilities and Climate. The institute makes weather forecasts and observations for Denmark, Greenland, and the Faroe Islands. History It was founded in 1873, largely through the efforts of Ludwig A. Colding. The Danish Meteorological Institute – DMI – encompasses the combined knowledge of the former Meteorological Institute, the Meteorological Service for Civil Aviation and the Meteorological Service for Defence. The Meteorological Institute was founded in 1872 under the Ministry of the Navy. The Meteorological Service for Civil Aviation was established in 1926, and used to be part of the Civil Aviation Administration. The Meteorological Service for Defence was established in 1953. The present-day DMI was established in 1990 through the merger of the three above-mentioned institutions. DMI is organized unde ...

Ice Cap Climate
An ice cap climate is a polar climate where no mean monthly temperature exceeds . The climate covers areas in or near the high latitudes (65° latitude) to polar regions (70–90° north and south latitude), such as Antarctica, some of the northernmost islands of Canada and Russia, Greenland, along with some regions and islands of Norway's Svalbard Archipelago that have vast deserts of snow and ice. Areas with ice cap climates are normally covered by a permanent layer of ice and have no vegetation. There is limited animal life in most ice cap climates, usually found near the oceanic margins. Although ice cap climates are inhospitable to human life, there are some small research stations scattered in Antarctica and interior Greenland. Description Under the Köppen climate classification, the ice cap climate is denoted as ''EF''. Ice caps are defined as a climate with no months above . Such areas are found around the north and south pole, and on the top of many high mountains. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Geodesic Dome
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size. History The first geodesic dome was designed after World War I by Walther Bauersfeld, chief engineer of the Carl Zeiss optical company, for a planetarium to house his planetarium projector. An initial, small dome was patented and constructed by the firm of Dykerhoff and Wydmann on the roof of the Zeiss plant in Jena, Germany. A larger dome, called "The Wonder of Jena", opened to the public in July 1926. Twenty years later, Buckminster Fuller coined the term "geodesic" from field experiments with artist Kenneth Snelson at Black Mountain College in 1948 and 1949. Although Fuller was not the original inventor, he is credited with the U.S. popularization of the idea for which he rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
