Bennett Platform
Bennett Platform () is a high, nearly flat, snow-free mesa of dark rock of Antarctica, about long and wide, located immediately east of Mount Black, on the west side of Shackleton Glacier. It was discovered and photographed by U.S. Navy Operation Highjump (1946–47), on the flights of February 16, 1947, and named by the Advisory Committee on Antarctic Names for Floyd Bennett Floyd Bennett (October 25, 1890 – April 25, 1928) was a United States Naval Aviator, along with then USN Commander Richard E.

Mesa
A mesa is an isolated, flat-topped elevation, ridge or hill, which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain. Mesas characteristically consist of flat-lying soft sedimentary rocks capped by a more resistant layer or layers of harder rock, e.g. shales overlain by sandstones. The resistant layer acts as a caprock that forms the flat summit of a mesa. The caprock can consist of either sedimentary rocks such as sandstone and limestone; dissected lava flows; or a deeply eroded duricrust. Unlike ''plateau'', whose usage does not imply horizontal layers of bedrock, e.g. Tibetan Plateau, the term ''mesa'' applies exclusively to the landforms built of flat-lying strata. Instead, flat-topped plateaus are specifically known as '' tablelands''.Duszyński, F., Migoń, P. and Strzelecki, M.C., 2019.

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 vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Black
Mount Black () is a prominent mountain of Antarctica, high, with a gentle snow-covered slope on its southwest side and a steep rock face on its northwest side, forming a part of the polar escarpment just west of Bennett Platform and the upper reaches of Shackleton Glacier. It was discovered and photographed by R. Admiral Byrd on his return flight from the South Pole in November 1929, and named by him for Van Lear Black, American financier and contributor to the Byrd Antarctic Expedition Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer. He was a recipient of the Medal of Honor, the highest honor for valor given by the United States, and was a pioneering American aviator, p ... of 1928–30 and 1933–35.

Shackleton Glacier
Shackleton Glacier is a major Antarctica, Antarctic glacier, over long and from 8 to 16 km (5 to 10 mi) wide, descending from the polar plateau from the vicinity of Roberts Massif and flowing north through the Queen Maud Mountains to enter the Ross Ice Shelf between Mount Speed and Waldron Spurs. The Roberts Zealand GSAE (1961–62), who named it for A.R. Roberts, leader at Scott Massif is a remarkable snow-free massif exceeding 2,700 metres (8,860 ft) and about 155 km2 (60 sq mi) in area. It was by the Southern Party of New United States Antarctic Program, USAS (1939–41) and named by US-SCAN for Sir Ernest Shackleton, Anglo-Irish people, Anglo-Irish Antarctic explorer.

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] |
Floyd Bennett
Floyd Bennett (October 25, 1890 – April 25, 1928) was a United States Naval Aviator, along with then USN Commander Richard E. Byrd, to have made the first flight to the North Pole in May 1926. However, their claim to have reached the pole is disputed. Biography Bennett was born in Warrensburg, New York, in 1890. He was an automobile mechanic before he enlisted in the Navy in 1917, during World War I. Bennett attended flight school, learned to fly and was rated as an Aviation Pilot. Bennett served with Richard E. Byrd on an aviation survey of Greenland in 1925, on which Byrd came to respect his ability as a pilot. North Pole flight Byrd named Bennett as his pilot for an attempt to reach the North Pole by air in 1926. The expedition was financed by John D. Rockefeller, Jr., Edsel Ford, Vincent Astor and T. F. Ryan. Bennett was at the controls on May 9 as the two men made their attempt, in a Fokker tri-motor called the ''Josephine Ford''. They returned to their airfield in Spitz ...

Richard E
Richard is a male given name. It originates, via Old French, from Frankish language, Old Frankish and is a Compound (linguistics), compound of the words descending from Proto-Germanic language, Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'.

Landforms Of The Ross Dependency
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
