Davisville Glacier
Davisville Glacier () is a glacier about long which drains the north slopes of the Wisconsin Range, between Lentz Buttress and Moran Buttress, and trends northwestward to merge with the lower portion of the Horlick Ice Stream. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for Davisville, Rhode Island, the location of the Construction Battalion Center responsible for cargo matters for U.S. Navy Operation Deep Freeze Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on.

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.

Wisconsin Range
The Wisconsin Range () is a major mountain range of the Horlick Mountains in Antarctica, comprising the Wisconsin Plateau and numerous glaciers, ridges and peaks bounded by the Reedy Glacier, Shimizu Ice Stream, Horlick Ice Stream and the interior ice plateau. The range was mapped by the USGS from surveys and U.S. Navy air photos, 1959–64. Named by US-ACAN for the University of Wisconsin–Madison, Madison, Wisconsin, which has sent numerous researchers to Antarctica. Most of the upland surface area of the range is the Wisconsin Plateau (), a large ice-capped plain with general elevations above . To the east and southeast, the plateau descends gradually and with only minor ice escarpments to merge with the interior ice plateau; to the north and west, the plateau displays abrupt escarpments and cliffs of over 1,000 metres. Mapped by USGS from surveys and U.S. Navy air photos, 1960–64. Named by US-ACAN in association with the Wisconsin Range. __NOTOC__ List of mountains This ...

Moran Buttress
Moran Buttress () is a steep bluff south of Koopman Peak, rising over and forming a major projection between Davisville Glacier and Quonset Glacier along the north wall of the Wisconsin Range in Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Clifford D. Moran, U.S. Navy, an aircraft pilot during Operation Deep Freeze Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on.

Horlick Ice Stream
Horlick Ice Stream () is a large ice stream on the featureless ice surface to the north of the main mass of the Horlick Mountains of Antarctica, draining west-southwestward, parallel to these mountains, to enter the lower portion of the Reedy Glacier. It was mapped by the U.S. Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names in association with the Horlick Mountains.

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] |
Davisville, Rhode Island
Davisville, Rhode Island is a village in the town of North Kingstown in the U.S. state of Rhode Island that was formerly the home of the Davisville Naval Construction Battalion Center, which housed the United States Navy's SeaBees. Village description Both Amtrak and MBTA's Providence/Stoughton Line pass through Davisville, though there is no railroad station here. A proposed MBTA station is currently being considered. Davisville NCBC It was located at Quonset Point on Narragansett Bay, an area now included in the town of North Kingstown. The Navy acquired the property in 1939 and built Naval Air Station Quonset Point. In 1942, adjoining properties were developed for training Seabees, including the Naval Construction Battalion Center (NCBC) at Davisville. After World War II, the Naval Air Station remained in operation, but the NCBC was inactive until 1951, when the site was designated Headquarters, NCBC. The Naval Air Station was decommissioned in 1974. NCBC Davisville was selecte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Deep Freeze
Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
