Boffa Island
Boffa Island is a rocky, ridge-like Antarctic island, long, lying half a kilometre east of Browning Peninsula between Bosner and Birkenhauer Islands, in the south part of the Windmill Islands. It was first mapped by USN Operation Highjump and Operation Windmill in 1947 and 1948. Named by the US-ACAN for W. C. Boffa, observer with the then Army Strategic Air Command (SAC), who assisted Operation Windmill parties in establishing astronomical control stations in the area in January 1948.

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 ...

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 ...

Antarctic
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, the Antarctic r ...

Browning Peninsula
Browning Peninsula () is a rocky peninsula, long, separating Penney Bay and Eyres Bay at the south end of the Windmill Islands.

Bosner Island
Bosner Island is an Antarctic rocky island, long, lying northwest of Boffa Island and half a kilometre east of Browning Peninsula in the south part of the Windmill Islands.

Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The operation was organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Ethan Erik Larson, USN, Commanding Officer, Task Force 68. Operation HIGHJUMP commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. HIGHJUMP's objectives, according to the U.S. Navy report of the operation, were: # Training personnel and testing equipment in frigid conditions; # Consolidating and extending the United States' sovereignty over the largest practicable area of the Antarctic continent (publicly denied as a goal before the expedition ended); # Determining the feasibility of establishing, maintaining, and utilizing bases in the Antarctic an ...

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 ...

US-ACAN
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]   |

Composite Antarctic Gazetteer
The Composite Gazetteer of Antarctica (CGA) of the Scientific Committee on Antarctic Research (SCAR) is the authoritative international gazetteer containing all Antarctic toponyms published in national gazetteers, plus basic information about those names and the relevant geographical features. The Gazetteer includes also parts of the International Hydrographic Organization (IHO) General Bathymetric Chart of the Oceans (GEBCO) gazetteer for under-sea features situated south of 60° south latitude. , the overall content of the CGA amounts to 37,893 geographic names for 19,803 features including some 500 features with two or more entirely different names, contributed by the following sources: {, class="wikitable sortable" !
