Beall Island
Beall Island is a rocky island with small coves indenting the eastern and western sides, lying south-west of the Bailey Peninsula, in the Windmill Islands on the Budd Coast of Antarctica. There are several small lakes on the island. It was first mapped from aerial photos taken by the USN's Operation Highjump and Operation Windmill in 1947 and 1948. It was named by the US-ACAN for James M. Beall, U.S. Weather Bureau observer with Operation Windmill who assisted staff aerology officers with forecasting duties. The Beall Reefs are submarine ridges with depths of less than , located west of the island; they were discovered at the establishment of Wilkes Station in 1961 and named by ANCA after the island. Connors Point is the north-western point of the island; it was named by the US-ACAN for Aerographer's Mate William J. Connors, USN, a member of the Wilkes Station party of 1958.

Windmill Islands
The Windmill Islands are an Antarctic group of rocky islands and rocks about wide, paralleling the coast of Wilkes Land for immediately north of Vanderford Glacier along the east side of Vincennes Bay. Kirkby Shoal is a small shoal area with depths of less than extending about westwards and SSW, about from the summit of Shirley Island, Windmill Islands, and NW of Stonehocker Point, Clark Peninsula. The Windmill Islands were mapped from aerial photographs taken by USN Operation Highjump, 1946–47. So named by the US-ACAN because personnel of Operation Windmill, 1947–48, landed on Holl Island at the southwest end of the group to establish ground control for USN Operation Highjump photographs. The term "Operation Windmill" is a popular expression which developed after the expedition disbanded and refers to the extensive use of helicopters made by this group. The official title of this expedition was the 'Second Antarctic Development Project', U.S. Navy Task Force 39, 1947†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Operation Windmill
Operation Windmill (OpWml) was the United States Navy's Second Antarctica Developments Project, an exploration and training mission to Antarctica in 1947–1948. This operation was a follow-up to the First Antarctica Development Project known as Operation Highjump. The expedition was commanded by Commander Gerald L. Ketchum, USN, and the flagship of Task Force 39 was the icebreaker USS ''Burton Island''. Missions during Operation Windmill varied including supply activities, helicopter reconnaissance of ice flows, scientific surveys, underwater demolition surveys, and convoy exercises. Malcolm Davis collected live animals, such as penguins and leopard seals, for zoological studies. The icebreaker USS ''Edisto'' (AG-89) sailed on 1 November 1947 for the Panama Canal to rendezvous with the ''Burton Island'' for the expedition.U.S. NAVY SECOND ANTARCTICA DEVELOPMENTS PROJECT, OPERATION WINDMILL, 1947–1948. http://www.south-pole.com/windmill.htm See also *List of Antarctic e ...

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] |
Radioman Gordon F
Radioman (RM) was a rating for United States Navy and United States Coast Guard enlisted personnel, specializing in communications technology. History of the rating The rating was created originally in 1921. In 1997, under the direction of Chief of Naval Operations Admiral Mike Boorda, the rating merged with the Data Processing Technician (DP) rating to form the Information Systems Technician (IT) rating. Both Radiomen and Data Processing Technicians in the Navy had to undergo general rate training and take a computer-based exam in order to be designated under the new IT rating. In 1996, the Submarine force merged Radioman with Electronics Technicians/ Electronic Warfare Specialist. The Coast Guard rating was renamed Telecommunications Specialist (TC) in 1995, which split in July 2003 to make up the Information System Technician (IT) and Operations Specialist (OS) ratings. Scope of work The Radiomen of the US Navy were responsible for transmitting and receiving radio sig ... [...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. History Navy personnel from the United States constructed the main part of Wilkes in a period of 16 days in January and February 1957, unloading 11,000 tons of material and supplies. It took a crew of over 100 to erect the station which housed 24 naval personnel and scientists for the next 18 months. As this was the time of the Cold War, there was considerable concern by the United States and Australia about Russian activity in Antarctica. Wilkes was seen to be strategically located because of its proximity to the south magnetic pole. Australia assumed custody of Wilkes, which remained the property of the U.S. State Department, in February 1959. Although Australia officially took over the operational command, the remain ...
