Ice Stream
An ice stream is a region of fast-moving ice within an ice sheet. It is a type of glacier, a body of ice that moves under its own weight. They can move upwards of a year, and can be up to in width, and hundreds of kilometers in length. They tend to be about deep at the thickest, and constitute the majority of the ice that leaves the sheet. In Antarctica, the ice streams account for approximately 90% of the sheet's mass loss per year, and approximately 50% of the mass loss in Greenland. The shear forces cause deformation and recrystallization that drive the movement, this movement then causes topographic lows and valleys to form after all of the material in the ice sheet has been discharged. Sediment also plays an important role in flow velocity, the softer and more easily deformed the sediment present, the easier it is for flow velocity to be higher. Most ice streams contain a layer of water at the bottom, which lubricates flow and acts to increase speed. Mechanics Ice str ...

Carroll Inlet () is an inlet, long and wide, trending southeast along the coast of Antarctica between the Rydberg Peninsula and Smyley Island.

Rydberg Peninsula
Rydberg Peninsula is a broad ice-covered peninsula, long, between Fladerer Bay and Carroll Inlet, Palmer Land. Rydberg Peninsula is located at . Rydberg Peninsula was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1961–1966. Rydberg Peninsula was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Captain Sven Rydberg, commander Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces.

English Coast
English Coast is a portion of the coast of Antarctica between the northern tip of Rydberg Peninsula and the Buttress Nunataks, on the west side of Palmer Land. To the west is Bryan Coast, and northward runs Rymill Coast east of Alexander Island across George VI Sound. This coast was discovered and explored in 1940, on land by Finn Ronne and Carl R. Eklund and from the air by other members of the East Base of the US Antarctic Service (USAS), 1939–41. It was originally named "Robert English Coast" after Capt. Robert A.J. English, US Navy, Executive Secretary of USAS, 1939–41, and formerly Captain of the '' Bear of Oakland'' on the Byrd Antarctic Expedition Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer.

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] |

USNS Eltanin (T-AK-270)
USNS ''Eltanin'' (T-AK-270/T-AGOR-8) was an ''Eltanin''-class cargo ship with an ice-breaking hull acquired by the U.S. Navy in 1957 and then operated by the Navy in a non-commissioned status, named after Eltanin, a star in the constellation Draco. Her designation was changed to that of an oceanographic research ship in 1962 when she operated in Antarctic waters. Construction ''Eltanin'' (T-AK-270) was launched on 16 January 1957 by Avondale Marine Ways, Inc., Avondale, Louisiana. She was turned over to the Military Sea Transportation Service (MSTS) in October 1957 for operation in a noncommissioned status. Conversion to research ship During 1961 and 1962, ''Eltanin'' was modified throughout at a New York shipyard to fill a new role as a floating laboratory. Former cargo spaces were replaced with labs, workshops, and staterooms for scientists, and further labs were added above decks. Anti-roll tanks were also added, along with protective bulwarks. On 23 August 1962 her cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
