Clapp Ridge
Clapp Ridge () is a narrow, steep-sided ridge about long, forming the north wall of Hand Glacier in the Victory Mountains, Victoria Land. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1960–64, and named by the Advisory Committee on Antarctic Names for James L. Clapp, a member of the United States Antarctic Research Program glaciological party to Roosevelt Island Roosevelt Island is an island in New York City's East River, within the borough of Manhattan. It lies between Manhattan Island to the west, and the borough of Queens, on Long Island, to the east. Running from the equivalent of East 46th to 85 ..., 1967–68.

Hand Glacier
Borchgrevink Glacier () is a large glacier in the Victory Mountains, Victoria Land, draining south between Malta Plateau and Daniell Peninsula, and thence projecting into Glacier Strait, Ross Sea, as a floating glacier tongue, the Borchgrevink Glacier Tongue, just south of Cape Jones. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, for Carsten Borchgrevink, leader of the British Antarctic Expedition, 1898–1900. Borchgrevink visited the area in February 1900 and first observed the seaward portion of the glacier. The Borchgrevink Glacier has several contributing glaciers: *Ingham Glacier (), a tributary glacier 3 miles (5 km) west of Humphries Glacier, flowing south into Borchgrevink Glacier; mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos, between 1960 and 1962. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Clayton E. Ingham, New Zealand geophysicist at Hallett Station, ...

Victory Mountains
The Victory Mountains () is a major group of mountains in Victoria Land, Antarctica, about long and wide, which is bounded primarily by Mariner and Tucker glaciers and the Ross Sea. The division between these mountains and the Concord Mountains (to the NW) is less precise but apparently lies in the vicinity of Thomson Peak. A Ross Sea aspect of the mountains was first obtained by early British expeditions of Ross, Borchgrevink, Scott and Shackleton. The mapping of the interior mountains was largely done from air photos taken by the U.S. Navy and surveys undertaken by New Zealand and American parties in the 1950s and 1960s. So named by the NZGSAE 1957-58, because of the proximity of this group to the Admiralty Mountains, and with the intention that many of the topographic features would be named for celebrated victories, especially naval victories.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...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 ...

Roosevelt Island, Antarctica
Roosevelt Island is the second largest ice rise of Antarctica and world-wide, after Berkner Island. Despite its name, it is not an island, since the bedrock below the ice at its highest part is below sea level. It is about long in a NW-SE direction, wide and about in area, lying under the eastern part of the Ross Ice Shelf of Antarctica. Its central ridge rises to about above sea level, but this and all other elevations of the ice rise are completely covered by ice, so that it is invisible at ground level. Examination of how the ice flows above it establishes the existence and extent of the ice rise. Radar surveying carried out between 1995 and 2013 showed that the Raymond Effect was operating beneath the ice divide. The ice rise has become a focus of the Roosevelt Island Climate Evolution (RICE) research using ice coring. Rear Admiral Richard E. Byrd named it in 1934 after US President Franklin D. Roosevelt. Byrd was the leader of the expedition that discovered the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridges Of Victoria Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
