Shabtaie Ice Ridge
Shabtaie Ice Ridge () is an ice ridge between MacAyeal Ice Stream and Bindschadler Ice Stream at the junction of Shirase Coast and Siple Coast, Marie Byrd Land. Named by Advisory Committee on Antarctic Names (US-ACAN) after Sion Shabtaie, Geophysical and Polar Research Center, University of Wisconsin, Madison, WI, who, with Charles R. Bentley, 1982–84 and 1985–86, made a glaciogeophysical survey of the nearby Mercer, Whillans and Kamb Ice Streams (formerly Ice Streams 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 t ...

MacAyeal Ice Stream
MacAyeal Ice Stream (), formerly Ice Stream E, is an ice stream in Antarctica flowing west to the juncture of Shirase Coast and Siple Coast between Bindschadler Ice Stream and Echelmeyer Ice Stream. It is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 onwards and named Ice Stream A, B, C, etc., according to their position from south to north. The name was changed from Ice Stream E by the Advisory Committee on Antarctic Names in 2002 to honor Douglas R. MacAyeal of the Department of Geophysical Sciences, University of Chicago, a U.S. Antarctic Program investigator in the Ross Sea area including study of the Ross Ice Shelf, the West Antarctic Ice Sheet and the Marie Byrd Land ice streams, 1989–2002.

Bindschadler Ice Stream
Bindschadler Ice Stream () is an ice stream between Siple Dome and MacAyeal Ice Stream. It is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983 to 1984 and named Ice Stream A, B, C, etc., according to their position from south to north. The name of this ice stream was changed from Ice Stream D by the Advisory Committee on Antarctic Names (ACAN) in 2001 or 2002 to honor Robert A. Bindschadler of the NASA Goddard Space Flight Center, a U.S. Antarctic Project investigator of the West Antarctic Ice Sheet including the dynamics of the Marie Byrd Land ice streams and their interaction with the Ross Ice Shelf, from about 1983 to 1998. In January 2003 the United States Board on Geographic Names accepted this recommendation, revising its 2000 decision; the geographic coordinates were also updated. Shabtaie Ice Ridge sit ...

Shirase Coast
Shirase Coast () is the north segment of the relatively ill-defined coast along the east side of Ross Ice Shelf and Ross Sea, lying between the north end of Siple Coast (about ) and Cape Colbeck. Named by NZ-APC in 1961 after Lieutenant Nobu Shirase (1861-1946), leader of the Japanese expedition, whose ship ''Kainan Maru'' sailed near this coast in January 1912. Landings were made at Kainan Bay and at the Bay of Whales, the origin of a 160-mile journey southeast on Ross Ice Shelf. From (off Edward VII Peninsula), another party landed for a sledge trip to the edge of the Queen Alexandra Range The Queen Alexandra Range is a major mountain range of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. It is about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau ....

Siple Coast
Siple Coast () is the middle portion of the relatively ill-defined coast along the east side of the Ross Ice Shelf, between the north end of Gould Coast () and the south end of Shirase Coast (). The area was originally called Kirton Coast, but was renamed by NZ-APC in 1961 after Paul A. Siple, a noted American scientist-explorer who accompanied R. Admiral Richard E. Byrd on all of his Antarctic expeditions. Further reading * Bindschadler, R.

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 ...

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] |

Charles R
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed i ...

Ice Streams
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 s ...
