Reid Spur
Ramsey Glacier () is a glacier about 45 nautical miles (80 km) long, originating in the Bush Mountains near the edge of the polar plateau and flowing north to the Ross Ice Shelf eastward of Den Hartog Peak. Discovered by the United States Antarctic Service (USAS) on Flight C of February 29-March 1, 1940, and named by Advisory Committee on Antarctic Names (US-ACAN), on the recommendation of R. Admiral Byrd, for Admiral DeWitt Clinton Ramsey, U.S. Navy, Vice Chief of Naval Operations during U.S. Navy Operation Highjump Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV.

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.

Bush Mountains
The Bush Mountains is a series of rugged elevations at the heads of the Ramsey and Kosco glaciers in Antarctica. The Bush Mountains extend from Mount Weir in the west to Anderson Heights overlooking Shackleton Glacier in the east. They were photographed at a distance by the Byrd Antarctic Expedition (Byrd AE) on several flights to the Queen Maud Mountains in November 1929. The mountains were further defined from aerial photographs taken by the USAS (1939–41), US Navy Operation Highjump (1946–47), and USN Operation Deep Freeze (1956–63). The Bush Mountains were named by US-SCAN, on the recommendation of Rear Admiral Byrd, after James I. Bush, American financier and patron of the Byrd AE, 1928–30.

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in the original U.S. Antarctic Gazetteer. In Januar ...

Den Hartog Peak
Den Hartog Peak () is a small peak at the west side of the mouth of Ramsey Glacier, 3 nautical miles (6 km) southeast of Woodall Peak. It was discovered and photographed by the United States Antarctic Service on Flight C of February 29 – March 1, 1940, and surveyed by A.P. Crary in 1957–58. It was named by Crary for Stephen Den Hartog, who was glaciologist on the Victoria Land Traverse Party (1958–59), and wintered at Little America V Little America was a series of Antarctic exploration bases from 1929 to 1958, located on the Ross Ice Shelf, south of the Bay of Whales.

United States Antarctic Service
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 ...

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] |

Vice Chief
A vice is a practice, behaviour, or habit generally considered immoral, sinful, criminal, rude, taboo, depraved, degrading, deviant or perverted in the associated society. In more minor usage, vice can refer to a fault, a negative character trait, a defect, an infirmity, or a bad or unhealthy habit. Vices are usually associated with a transgression in a person's character or temperament rather than their morality. Synonyms for vice include fault, sin, depravity, iniquity, wickedness, and corruption. The antonym of vice is virtue. Etymology The modern English term that best captures its original meaning is the word ''vicious'', which means "full of vice". In this sense, the word ''vice'' comes from the Latin word '' vitium'', meaning "failing or defect". Law enforcement Depending on the country or jurisdiction, vice crimes may or may not be treated as a separate category in the criminal codes. Even in jurisdictions where vice is not explicitly delineated in the legal code, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
