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] |

Wilkes Station
Wilkes Station was an Antarctic research station established 29 January 1957 by the United States as one of seven U.S. stations established for the International Geophysical Year (IGY) program in Antarctica. It was taken over by Australia on 7 February 1959. Environmental difficulties at this site lead to it being abandoned in 1969, with the Australians establishing a new base, Casey Station. History Wilkes Station was named after Charles Wilkes, a 19th-century American explorer who discovered the phenomenon of the continental margin, which helped prove that Antarctica was a continent. Wilkes was one of seven bases that the United States built for the IGY, which also included McMurdo, Hallett, Admundsen-Scott (South Pole Station), Ellsworth, Byrd, and Little America. Of these only McMurdo and Admundsen-Scott are still operated by the 21st century. Personnel from the United States Navy constructed the main part of Wilkes in a period of 16 days in January and February 19 ...
