Barnes Ridge (Antarctica)
Barnes Ridge () is a ridge long, rising to over (Mount Besch) and extending between Young Glacier and Ellen Glacier at the east side of the Sentinel Range, Ellsworth Mountains in Antarctica. It is bounded by Rutford Ice Stream to the east and Arapya Glacier to the west, and connected to Maglenik Heights to the northwest by Dropla Gap. Its eastern slopes are drained by Ranuli Ice Piedmont. The ridge was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Stephen S.

Arapya Glacier
Arapya Glacier ( bg, ледник Арапя, lednik Arapya, ) is the long and wide glacier on the east side of north-central Sentinel Range in Ellsworth Mountains, Antarctica, situated south of Young Glacier. It flows southwards along the west side of Barnes Ridge and east of Chapman Peak and joins Ellen Glacier southwest of Mount Besch. The glacier is named after the seaside locality of Arapya in Southeastern Bulgaria. Location Arapya Glacier is centred at . US mapping in 1961, updated in 1988.

Stephen S
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ; related names that have found some curr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 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 ...

Ranuli Ice Piedmont
Ranuli Ice Piedmont ( bg, ледник Ранули, lednik Ranuli, ) is the glacier extending in south-southeast to north-northwest direction and in west-southwest to east-northeast direction on the east side of Sentinel Range in Ellsworth Mountains, Antarctica. It is draining the east slopes of Barnes Ridge to flow into Rutford Ice Stream to the east-northeast, Young Glacier to the north, and Ellen Glacier to the south. The feature is named after the ancient town of Ranuli in southeastern Bulgaria. Location Ranuli Ice Piedmont is located at . US mapping in 1988.

Rutford Ice Stream
Rutford Ice Stream () is a major Antarctic ice stream, about long and over wide, which drains southeastward between the Sentinel Range, Ellsworth Mountains and Fletcher Ice Rise into the southwest part of Ronne Ice Shelf. Named by US-ACAN for geologist Robert Hoxie Rutford, a member of several USARP expeditions to Antarctica; leader of the University of Minnesota Ellsworth Mountains Party, 1963-1964. Rutford served as Director of the Division of Polar Programs, National Science Foundation, 1975-1977. The ice stream is situated in a deep trough which is a tectonic feature between the Ellsworth Mountains and the Fletcher Promontory. Because of this the ice stream position may have been stable for millions of years. The bed of the ice stream reaches below sea level. Therefore, between the bed of the ice stream and the height of the Ellsworth Mountains there is a vertical relief of over a distance of only . At the upper (inland) end of the ice stream the ice thickness reache ... [...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 ...

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]   |
