Severinghaus Glacier
Severinghaus Glacier () is a glacier flowing southwestward from Karnare Col along the north side of Mount Strybing and the south side of Mount Craddock into Bender Glacier in southern Sentinel Range, Ellsworth Mountains in Antarctica. Named by the US-ACAN (2006) after Jeffrey P. Severinghaus, University of Rhode Island Graduate School of Oceanography; USAP researcher from 1996 on the history of the atmosphere, including greenhouse gases, and history of climate changes, using the ice core record.

Sentinel Range
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about and is 24 to 48 km (15 to 30 mi) wide. Many peaks rise over and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.Sentinel Range. SCAR Composite Antarctic Gazetteer. Sentinel Range comprises a main ridge (featuring Vinson Massif in its southern portion) and a number of distinct heights, ridges and mountains on its east side, including (south to north) , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 vegetation o ... [...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 Antarct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bender Glacier
Bender Glacier () is a glacier that flows from Mount Atkinson and Mount Craddock southwards between Chaplin Peak and Krusha Peak, and joins Nimitz Glacier just south of Gilbert Spur in the southern Sentinel Range, Ellsworth Mountains in Antarctica. Receiving ice influx from its left tributaries Severinghaus Glacier, Brook Glacier and Bolgrad Glacier. It was named by the Advisory Committee on Antarctic Names (2006) after Professor Michael L. Bender at the Department of Geosciences (Geochemistry), Princeton University (earlier at the Graduate School of Oceanography, University of Rhode Island), whose paleoclimate research from 1984 centered on the glacial-interglacial climate change and the global carbon cycle.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Mount Strybing
Mount Strybing () is a mountain (3,200 m) standing on Owen Ridge 3 nautical miles (6 km) southeast of Mount Craddock in the south part of Sentinel Range, Ellsworth Mountains. It is linked to Mount Craddock by Karnare Col, and surmounts Saltzman Glacier to the northeast, Brook Glacier to the southwest, and Severinghaus Glacier to the west-northwest. The peak was first mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos from 1957 to 1959. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for M/Sgt.

Mount Craddock
Mount Craddock is a large, bold mountain forming the south extremity of Craddock Massif in Sentinel Range, the ninth highest mountain in Antarctica. It is linked by Karnare Col to Mount Strybing in the southern Sentinel Range. The ninth-highest mountain in Antarctica was first climbed in January 1992. The name Mount Craddock was originally recommended by the Advisory Committee on Antarctic Names (US-ACAN) in 1965 for the present-day Craddock Massif but subsequent maps limited Mount Craddock to the massif's southernmost peak, a position that became established over years. To avoid confusion and to fix the position of the name, US-ACAN redefined Mount Craddock in 2006 to apply to the southernmost peak described above.USGS GNIS The mountain was named by US-ACAN for J. Campbell Craddock (1930–2006), leader of a University of Minnesota expedition (1962–63) that made geological investigations and cartographic surveys in the Sentinel and Heritage Ranges of the Ellsworth Mountain ...

Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015. ''Soils of Ellsworth Land, the Ellsworth Mountains''. In: Bockheim, J.G. (Ed.), ''The Soils of Antarctica. World Soils Book Series'', Springer, Switzerland, pp. 169–181. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. Discovery The mountains were discovered on November 23, 1935, by Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf. He gave them the descriptive name Sentinel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US-ACAN
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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
