Bear Peninsula
Bear Peninsula () is a peninsula about 80 km (50 mi) long and 40 km (25 mi) wide which is ice covered except for several isolated rock bluffs and outcrops along its margins, lying 48 km 30 mi) east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica. First delineated from aerial photographs taken by USN Operation Highjump in January 1947. Named by the Advisory Committee on Antarctic Names (US-ACAN) after the ice-ship ''USS Bear'', flagship of the USAS, from which three reconnaissance flights were made in late February 1940, resulting in the discovery of Walgreen Coast (with probable sighting of this feature) and the Thurston Island area. This ship, under the name Bear of Oakland, also served as flagship of the Byrd AE, 1933–35, which based at the Bay of Whales, Ross Ice Shelf. Launched in 1874 at Greenock, Scotland, for use in the sealing trade, she sank in 30-foot seas and high winds in the North Atlantic, March 19, 1963, at which ti ...

Brush Glacier
Brush Glacier () is a broad glacier in the northwest part of the Bear Peninsula, flowing west into Dotson Ice Shelf to the north of Jeffrey Head, in Marie Byrd Land. The head of the glacier is marked by rocky, wedge-shaped Rogers Spur. Webster Pass divides Brush Glacier from Holt Glacier. Both features were first mapped by the United States Geological Survey (USGS) from air photos taken by U.S. Navy Operation Highjump in January 1947, and named by the Advisory Committee on Antarctic Names (US-ACAN) for personnel at the Byrd Substation. The glacier was named for station engineer Bernard E. Brush and the spur for electrical engineer James C. Rogers James is a common English language surname and given name: *James (name), the typically masculine first name James * James (surname), various people with the last name James James or James City may also refer to: People * King James (disambiguati ....

Holt Glacier
Holt Glacier () is a broad glacier on Bear Peninsula that flows east to the sea between Grimes Ridge and the Jones Bluffs in Marie Byrd Land, Antarctica. It was first delineated by the United States Geological Survey from air photos taken by U.S. Navy Operation Highjump in January 1947, and was named by the Advisory Committee on Antarctic Names after Joseph V. Holt, a member of the U.S. Army Aviation Detachment in Antarctica, 1965–66. Webster Pass divides Brush Glacier from Holt Glacier.

Walgreen Coast
The Walgreen Coast () is a portion of the coast of Antarctica between Cape Herlacher and Cape Waite, or between Eights Coast on the east and Bakutis Coast in the west. It is part of Marie Byrd Land. It extends from 103°24'W to 114°12'W. It was discovered by Richard E. Byrd and members of the US Antarctic Service (USAS) by flights from the USS ''Bear'' during February 1940. The Walgreen Coast was named by Byrd after Charles R. Walgreen, president of the retail company Walgreens at the time, who was a funder of the Byrd Antarctic Expedition, 1933–1935, and assisted in equipping the ''Bear'' for the USAS, 1939–1941. This coast was mapped in detail by the United States Geological Survey from ground surveys and U.S. Navy air photographs, 1959–66. It contains Thwaites Glacier, also known as the "Doomsday Glacier", for its major contributions to sea level rise as a result of climate change.

Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of (including Eights Coast, immediately east of Marie Byrd Land). In 1939, United States President F ...

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 hundredth 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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operation Deepfreeze
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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Passes Of Antarctica
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
