Summit (topography)
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 ...

Admiralty Mountains
The Admiralty Mountains (alternatively Admiralty Range) is a large group of high mountains and individually named ranges and ridges in northeastern Victoria Land, Antarctica. This mountain group is bounded by the Ross Sea, the Southern Ocean, and by the Dennistoun, Ebbe, and Tucker glaciers. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. It was discovered in January 1841 by Captain James Ross, who named them for the Lords Commissioners of the Admiralty under whose orders he served. The Admiralty Mountains are divided into the Dunedin Range, Homerun Range, and Lyttelton Range. Mountains and peaks This range includes the following mountains and peaks: Mount Achilles Mount Achilles is a prominent pyramidal mountain rising from the divide between Fitch Glacier and Man-o-War Glacier. Named by New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58, after the former New Zealand cruiser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Antarctic Research Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Otto Ludwig Lange
Otto Ludwig Lange (21 August 1927 – 14 August 2017 in Würzburg) was a German botanist and lichenologist. The focus of his scientific work was on the ecophysiology of wild and cultivated plants as well as lichens. He investigated heat, frost and drought resistance of lichens, bryophytes and vascular plants growing under extreme environmental conditions. Life and education Otto Lange was born in Dortmund on 21 August 1927. His family moved to Göttingen, where he went to school. Lange was drafted into the German army at age 16, and became a prisoner of war. This experience affected him greatly as a young man, and later in life he supported anti-war activism. After his return home, he studied biology, chemistry and physics at the Universities of Freiburg and Göttingen. It was from this latter institution that he earned his doctorate degree in 1952, defending a thesis titled "Heat and drought tolerance of lichens in relation to their geographic distribution". His supervisor wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallett Station
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oil stored in several large tanks. This is an ongoing project which will take several years to complete. Antarctic Specially Protected Area An area of 74 ha is protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.106 because it contains habitats with a rich and diverse range of ...

Mountains Of Victoria Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
