Branscomb Glacier
The Branscomb Glacier () is an Antarctic glacier, long, flowing west from the north-west side of Vinson Massif (the highest point in Antarctica) into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains. Its upper course receives ice influx from both Goodge Col and Jacobsen Valley, while the tributary Roché Glacier joins Branscomb Glacier just northwest of Príncipe de Asturias Peak. The glacier was mapped by the USGS from surveys and USN aerial photographs between 1957 and 1960. It was named by US-ACAN after Lewis M. Branscomb, Chairman of the National Science Board from 1982 to 1984.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where ve ... [...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 ...

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacia ...

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

National Science Board
The National Science Board (NSB) of the United States establishes the policies of the National Science Foundation (NSF) within the framework of applicable national policies set forth by the President and the Congress. The NSB also serves as an independent policy advisory body to the President and Congress on science and engineering research and education issues. The Board has a statutory obligation to "...render to the President and to the Congress reports on specific, individual policy matters related to science and engineering and education in science engineering, as Congress or the President determines the need for such reports," (e.g. Science and Engineering Indicators; Report to Congress on Mid-scale Instrumentation at the National Science Foundation). All Board members are presidential appointees. NSF's director serves as an ex officio 25th member and is appointed by the President and confirmed by the US Senate.

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] |

Ellsworth Land
Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by Bellingshausen Sea, on the northeast by the base of Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W. It is largely a high ice plateau, but includes the Ellsworth Mountains and a number of scattered mountain groups: Hudson, Jones, Behrendt, Hauberg, Merrick, Sweeney and Scaife Mountains. This land lies near the center of the area traversed by American explorer Lincoln Ellsworth on an airplane flight during November–December 1935. It was named for him by the Advisory Committee on Antarcti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roché Glacier
Roché Glacier ( bg, ледник Роше, lednik Roshe, ) is the 5.8 km long and 2 km wide glacier draining the central part of Vinson Plateau in Sentinel Range, Ellsworth Mountains in Antarctica. Its head is bounded by Mount Vinson to the north, Corbet Peak and Clinch Peak to the east, Wahlstrom Peak to the southeast, and Hollister Peak to the south, with the glacier flowing westwards and descending steeply north of Silverstein Peak to join Branscomb Glacier. The glacier is named after the British pioneer of Antarctica Anthony de la Roché who discovered the first land in the Antarctic region ( Roché Island, present South Georgia) in 1675. Location Roché Glacier is centred at . US mapping in 1961, 1988 and 2007.
