Holmes Hills
The Holmes Hills () are a group of ridges and nunataks rising to about between Runcorn Glacier and Beaumont Glacier, bounded to the southwest by the Brennecke Nunataks, in south-central Palmer Land, Antarctica. They were mapped by the United States Geological Survey from aerial photographs taken by the U.S. Navy, 1966–69, and surveyed by the British Antarctic Survey, 1972–73. In association with the names of continental drift scientists grouped in this area, the hills were named by the Advisory Committee on Antarctic Names in 1978 after Scottish geologist Arthur Holmes, Professor of Geology at the University of Edinburgh The University of Edinburgh ( sco, University o Edinburgh, gd, Oilthigh Dhùn Èideann; abbreviated as ''Edin.'' in post-nominals) is a public research university based in Edinburgh, Scotland.

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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runcorn Glacier
Runcorn Glacier () is a glacier to the west of Hess Mountains in Antarctica. It flows southeast to join Beaumont Glacier near the head of Hilton Inlet, Black Coast, Palmer Land. The glacier was mapped by United States Geological Survey (USGS) from aerial photographs taken by the U.S. Navy during 1966–69, and surveyed by British Antarctic Survey during 1972–73. In association with the names of continental drift scientists grouped in this area, the Advisory Committee on Antarctic Names named the glacier after Keith Runcorn in 1998. Runcorn was an English geophysicist whose paleomagnetic reconstruction of the relative motions of Europe and America revived the theory of continental drift and was a major contribution to plate tectonics Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large . ...

Beaumont Glacier
Beaumont Glacier () is a broad glacier flowing in a northeast direction to the southwest part of Hilton Inlet, on the east coast of Palmer Land. The United States Antarctic Service discovered and photographed it from the air in 1940. It was resighted in 1947 by the Ronne Antarctic Research Expedition under Finn Ronne, who named it for the city of Beaumont, Texas, in recognition of the public support given to his expedition by this city and by the Tejas Chapter of the Daughters of the Republic of Texas The Daughters of the Republic of Texas (DRT) is a lineal association dedicated to perpetuating the memory of the founding families and soldiers of the Republic of Texas.

Brennecke Nunataks
The Brennecke Nunataks () are a group of large nunataks on the north side of the head of Beaumont Glacier, to the southwest of the Holmes Hills in south-central Palmer Land. They were mapped by the United States Geological Survey from aerial photographs taken by the U.S. Navy, 1966–69. In association with the names of oceanographers grouped in this area, the group was named by the UK Antarctic Place-Names Committee after Carl Wilhelm A. Brennecke (1875–1924), German oceanographer; member of the staff of Deutsche Seewarte (German Naval Observatory), 1904–24; member of the Second German Antarctic Expedition The Second German Antarctic Expedition of 1911–1913 was led by Wilhelm Filchner in the exploration ship . Its principal objective was to determine whether the Antarctic continent comprised a single landmass rather than separated elements, and i ..., 1911–12.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Decepti ...

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the British Admiralty, Admiralty and the Secretary of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Arthur Holmes
Arthur Holmes (14 January 1890 – 20 September 1965) was an English geologist who made two major contributions to the understanding of geology. He pioneered the use of radiometric dating of minerals, and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics. Life He was born in Hebburn, County Durham, near Newcastle upon Tyne, the son of David Holmes, a cabinet-maker, and his wife, Emily Dickinson. As a child, he lived in Low Fell, Gateshead, and attended the Gateshead Higher Grade School (later Gateshead Grammar School). At 17, he enrolled to study physics at the Royal College of Science (now Imperial College London), but took a course in geology in his second year, which settled his future, against the advice of his tutors. Surviving on a scholarship of £60/year was difficult and on graduating hall, he took a job prospecting for minerals in Mozambique. After six month ...

Ridges Of Palmer Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
