Rochray Glacier
Rochray Glacier () is a glacier about 5 nautical miles (9 km) long, located just east of Hendersin Knob on Thurston Island and flowing south to Abbot Ice Shelf in Peacock Sound. First delineated from air photos taken by U.S. Navy Operation Highjump in December 1946. Named by Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant (j.g.) Samuel Rochray, U.S. Navy, helicopter pilot on USS Glacier in February 1960, who made several flights in which new parts of Thurston Island were discovered. Jordan Nunatak stands between Rochray and Cox Glacier. See also * List of glaciers in the Antarctic There are many glaciers in the Antarctic.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellsworth Land
Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by Bellingshausen Sea, on the northeast by the base of Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W. It is largely a high ice plateau, but includes the Ellsworth Mountains and a number of scattered mountain groups: Hudson, Jones, Behrendt, Hauberg, Merrick, Sweeney and Scaife Mountains. This land lies near the center of the area traversed by American explorer Lincoln Ellsworth on an airplane flight during November–December 1935. It was named for him by the Advisory Committee on Antarc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peacock Sound
Peacock Sound is an ice-filled sound, long and wide, separating Thurston Island from the Eights Coast of Ellsworth Land in Antarctica. The sound is occupied by the western part of the Abbot Ice Shelf, and is therefore not navigable by ships. The feature was discovered by members of the United States Antarctic Program in flights from the ship USS ''Bear'' in February 1940, and was further delineated from air photos taken by US Navy Operation HIGHJUMP in December 1946. The sound was first noted to parallel the entire south coast of Thurston Island, thereby establishing insularity, by the USN Bellingshausen Sea Expedition in February 1960. Named after the sloop-of-war USS ''Peacock'' in which Captain William L. Hudson, in company with the tender USS ''Flying Fish'' under Lt. William M. Walker, both of the United States Exploring Expedition, 1838–42, sailed along the edge of the pack ice to the north of Thurston Island for several days in March 1839. Further reading * Defen ...

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 over many years, often centuries. It acquires distinguishing features, such as crevasses and 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. Between latitudes 35°N and 35°S, glaciers occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hendersin Knob
Walker Mountains () is a range of peaks and nunataks which are fairly well separated but trend east–west to form the axis, or spine, of Thurston Island in Antarctica. They were discovered by Rear Admiral Byrd and members of the US Antarctic Service in a flight from the ship ''Bear'' on February 27, 1940. It was named by the Advisory Committee on Antarctic Names for Lt. William M. Walker, captain of the United States Exploring Expedition ship ''Island'' on March 23, 1839.

Thurston Island
Thurston Island is an ice-covered, glacially dissected island, long, wide and in area, lying a short way off the northwest end of Ellsworth Land, Antarctica. It is the third-largest island of Antarctica, after Alexander Island and Berkner Island. The island was discovered from the air by Rear Admiral Byrd on February 27, 1940, who named it for W. Harris Thurston, a New York textile manufacturer, designer of the windproof " Byrd Cloth" and sponsor of Antarctic expeditions. Thurston Island is separated from the mainland by Peacock Sound, which is occupied by the western portion of Abbot Ice Shelf. It divides Bellingshausen Sea to the east from Amundsen Sea to the west. Originally mistaken as a peninsula, the feature was not recognised an island until 1960. Geography The western extremity of the island is Cape Flying Fish. The eastern extremity is Cape Annawan, off Tierney Peninsula. The southeast end of the island is Cape Walker. The island is divided south-north by ...

Abbot Ice Shelf
The Abbot Ice Shelf is an ice shelf long and wide, bordering Eights Coast from Cape Waite to Pfrogner Point in Antarctica. Thurston Island lies along the northern edge of the western half of this ice shelf; other sizable islands ( Sherman, Carpenter, Dustin, Johnson, McNamara, Farwell and Dendtler) lie partly or wholly within this shelf. The ice shelf was sighted by members of the U.S. Antarctic Service in flights from the ship ''Bear'', in February 1940, and its western portion was delineated from air photos taken by U.S. Navy (USN) Operation HIGHJUMP, 1946–47. The full extent was mapped by the U.S. Geological Survey from USN air photos of 1966. It was named by the Advisory Committee on Antarctic Names for Rear Admiral James Lloyd Abbot, Jr., Commanding Officer, U.S. Naval Support Force, Antarctica, February 1967 to June 1969.

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] |
