Harold Byrd Mountains
The Harold Byrd Mountains (), also known more simply as the Byrd Mountains, are a group of exposed mountains and nunataks which extend in an east–west direction between the lower part of Leverett Glacier and the head of the Ross Ice Shelf in Antarctica. They were discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by Rear Admiral Richard E. Byrd Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leverett Glacier
Leverett Glacier in Antarctica is about long and wide, draining northward from the Watson Escarpment, between California Plateau and Stanford Plateau, and then trending west-northwest between the Tapley Mountains and Harold Byrd Mountains to terminate at the head of the Ross Ice Shelf close east of Scott Glacier. It was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by him for Frank Leverett, an eminent geologist at the University of Michigan and an authority on the glacial geology of the central United States. Leverett Glacier is on the route through the Transantarctic Mountains The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted (primarily sedimentary) rock in Antarctica which extend, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. ... for the McMurdo – South Pole Highway, an overland supply route between McMurdo ...

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 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 located in the east of the Ross Sea. The ice shelf is named after 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 the original U.S. Antarctic Gazetteer. In Januar ...

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] |
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, 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. Byrd said that his expeditions had been the first to reach both the North Pole and the South Pole by air. His belief to have reached the North Pole is disputed. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Family Ancestry Byrd was born in Winchester, Virginia, the son of Esther Bolling (Flood) and Richard Evelyn Byrd Sr. He was a descendant of one of the First Families of Virginia. His ancestors include planter John Rolfe and his wife Pocahontas, William Byrd II of Westover Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laurence Gould
Laurence McKinley Gould (August 22, 1896 – June 21, 1995) was an American geologist, educator, and polar explorer. He made expeditions to both the Arctic and Antarctic, and was chief scientist on Richard Evelyn Byrd's first Antarctic expedition, which Gould described in his 1931 book ''Cold: the Record of an Antarctic Sledge Journey.'' He served as president of Carleton College from 1945 to 1962, and president of the American Association for the Advancement of Science in 1964. His namesakes include the research vessel ''Laurence M. Gould'' as well as Antarctic features including Gould Bay, Gould Coast, and Mount Gould. Biography Gould was born in Lacota, Michigan on August 22, 1896. After completing high school in South Haven, Michigan in 1914, he went to Boca Raton, Florida and taught grades 1 to 8 in a one-room school for two years, while saving money for college. He enrolled at the University of Michigan in 1916, but interrupted his education the following year to enlist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
