Fletcher Nunataks
The Grossman Nunataks () are a group of about a dozen nunataks in Palmer Land, Antarctica, rising in elevation and running northwest–southeast for between the Lyon Nunataks and the Sky-Hi Nunataks. The group includes features from the Smith Nunataks and the Whitmill Nunatak in the northwest to Gaylord Nunatak and Neff Nunatak in the southeast. The group was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy aerial photographs, 1961–68, and from U.S. Landsat imagery, 1973–74. It was named by the Advisory Committee on Antarctic Names in 1994 after Charles Grossman Charles is a masculine given name predominantly found in English and French speaking countries.

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] |
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 Deceptio ...

Sky-Hi Nunataks
Sky-Hi Nunataks is a nunatak group 8 nautical miles (15 km) long, located 11 nautical miles (20 km) east of Grossman Nunataks and northeast of Merrick Mountains in Palmer Land, extending from Doppler Nunatak in the west to Arnoldy Nunatak in the east and including Mount Mende, Mount Lanzerotti, Mount Carrara, and Mount Cahill. History The nunataks were first seen and photographed from the air by Ronne Antarctic Research Expedition (RARE), 1947–48. The name derives from the United States Antarctic Research Program (USARP) project Sky-Hi, in which Camp Sky-Hi (later designated Eights Station) was set up in Ellsworth Land in November 1961 as a conjugate point station to carry on simultaneous measurements of the earth's magnetic field and of the ionosphere. Sky-Hi's conjugate point in the Northern Hemisphere is located in the Réserve faunique des Laurentides, in Canada.

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or ... [...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 Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Grossman
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depre ...
