Karo Hills
The Karo Hills () are rounded, ice-free foothills in Antarctica extending for along the west side of the terminus of Scott Glacier, from Mount Salisbury north-northwest to the edge of the Ross Ice Shelf. Discovery and naming The Karo Hills were first seen and roughly mapped by the Byrd Antarctic Expedition between 1928 and 1930, and were named by the Advisory Committee on Antarctic Names for Vice Admiral Henry Arnold Karo, Director of the United States Coast and Geodetic Survey from 1955 to 1965 and Deputy Director of the U.S. Environmental Science Services Administration from 1965 to 1967. Location The Karo Hills run north-northeast from Mount Salisbury in the south, separating the Koerwitz Glacier to the west from the Scott Glacier to the east. Other peaks include Mount Hastings and Mount Rigby. Features Mount Salisbury . An ice-free mountain, high, standing at the west side of the lower Scott Glacier at the south end of the Karo Hills.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic 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 Climate of Antarctica#Precipitation, 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 temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Scott Glacier (Transantarctic Mountains)
The Scott Glacier () is a major glacier, long, that drains the East Antarctic Ice Sheet through the Queen Maud Mountains to the Ross Ice Shelf. The Scott Glacier is one of a series of major glaciers flowing across the Transantarctic Mountains, with the Amundsen Glacier to the west and the Leverett and Reedy glaciers to the east. Geography The Scott Glacier originates on the Antarctic Plateau in the vicinity of D'Angelo Bluff and Mount Howe, and descends between the Nilsen Plateau and the mountains of the Watson Escarpment to enter Ross Ice Shelf just west of the Tapley Mountains. The Tapley Mountains, Watson Escarpment, Mount Blackburn, and the La Gorce Mountains bound the Scott Glacier on its eastern margin, while the Karo Hills, Hays Mountains, Faulkner Escarpment, and Rawson Mountains define the western edge of the Scott's drainage. According to ''Sailing Directions for Antarctica'' (1960),"Eastward of the Amundsen Glacier the foothills are more nearly subme ...

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of the Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island, Antarctica, Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after James Clark Ross, Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byrd Antarctic Expedition
Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an United States Navy, American naval officer, and pioneering aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Byrd claimed to be the first to reach both the North Pole, North and South Poles by air. However, there is some controversy as to whether Byrd was actually the first person to reach the North Pole. It is generally believed that the distance Byrd claimed to fly was longer than the possible fuel range of his airplane. He was a List of Medal of Honor recipients during peacetime, recipient of the Medal of Honor, the United States Armed Forces' highest military decoration, and the Navy Cross, the second highest honor for valor given by the U ...

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] |

United States Coast And Geodetic Survey
The United States Coast and Geodetic Survey ( USC&GS; known as the Survey of the Coast from 1807 to 1836, and as the United States Coast Survey from 1836 until 1878) was the first scientific agency of the Federal government of the United States, United States Government. It existed from 1807 to 1970, and throughout its history was responsible for mapping and charting the coast of the United States, and later the coasts of Territories of the United States, U.S. territories. In 1871, it gained the additional responsibility of surveying the interior of the United States and geodesy became a more important part of its work, leading to it being renamed the U.S. Coast and Geodetic Survey in 1878. Long the U.S. government's only scientific agency, the Survey accumulated other scientific and technical responsibilities as well, including astronomy, cartography, metrology, meteorology, geology, geophysics, hydrography, navigation, oceanography, exploration, Piloting, pilotage, tides, and ...

Hills Of Antarctica
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit, and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as mountains. Hills fall under the category of slope landforms. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the UK government's Countryside and Rights of Way Act 2000 defined mountainous areas (for the ...
