Vincennes Bay
Vincennes Bay is a large V-shaped bay, 105 km (65 mi) wide at its entrance between Cape Nutt and Cape Folger in Antarctica, marked by several large, steep glaciers near its head, lying along Knox and Budd Coasts. It was photographed from the air by US Navy Operation Highjump in 1946–47. The bay was entered in January 1948 by US Navy Operation Windmill icebreakers Burton Island and stations in the Windmill Islands in the NE portion of the bay. Named by the US-ACAN for the sloop of war , flagship of the USEE under Wilkes, from which a series of coastal landfalls along Wilkes Land were discovered and plotted during January–February 1840. Wilkes' chart suggests a possible coastal recession corresponding closely with the longitudinal limits for Vincennes Bay, although pack ice conditions prevented close reconnaissance by the USEE of the coast in this immediate area. Vincennes Bay is roughly triangular, 120 km north–south and 150 km east–west at its nor ... [...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] |
Charles Wilkes
Charles Wilkes (April 3, 1798 – February 8, 1877) was an American naval officer, ship's captain, and explorer. He led the United States Exploring Expedition (1838–1842). During the American Civil War (1861–1865), he commanded ' during the Trent Affair in which he stopped a Royal Mail ship and removed two Confederate diplomats, which almost led to war between the United States and the United Kingdom. Early life and career Wilkes was born in New York City, on April 3, 1798, as the great nephew of the former Lord Mayor of London John Wilkes. His mother was Mary Seton, who died in 1802 when Charles was just three years old. As a result, Charles was raised by his aunt, Elizabeth Ann Seton, who would later convert to Roman Catholicism and become the first American-born woman canonized a saint by the Catholic Church. When Elizabeth was left widowed with five children, Charles was sent to a boarding school, and later attended Columbia College, which is the present-day Columbia Uni ...

Adams Glacier (Wilkes Land)
Adams Glacier (), also known as John Quincy Adams Glacier, is a broad channel glacier in Wilkes Land, Antarctica which is over long. It debouches into the head of Vincennes Bay, just east of Hatch Islands. It was first mapped in 1955 by G.D. Blodgett from aerial photographs taken by U.S. Navy Operation Highjump (1947), and it was named by the Advisory Committee on Antarctic Names (US-ACAN) for John Quincy Adams, sixth President of the United States. Adams was instrumental while later serving as U.S. representative from Massachusetts in gaining congressional authorization of the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes, and perpetuating the compilation and publication of the large number of scientific reports based on the work of this expedition.

Vanderford Glacier
Vanderford Glacier () is a glacier about 8 km (5 mi) wide flowing northwest into the southeast side of Vincennes Bay, slightly south of the Windmill Islands. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Benjamin Vanderford, pilot of the sloop of war Vincennes of the United States Exploring Expedition under Captain Wilkes, 1838–42. The glacier was mapped from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47.

Casey Station
Casey Station, commonly called Casey, is one of three permanent stations and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Casey lies on the northern side of the Bailey Peninsula (Antarctica), Bailey Peninsula overlooking Vincennes Bay on the Budd Coast of Wilkes Land in the Australian Antarctic Territory, a States and territories of Australia, territory claimed by Australia. Casey is due south of Perth, Western Australia, Perth, Western Australia. Casey was named in honour of Richard Casey, Baron Casey, Richard, Baron Casey. History Casey is close to the now-abandoned Wilkes Station, established by the United States of America to support science and exploration of Antarctica during the International Geophysical Year (IGY) in 1957–1958. Australia took Wilkes over after the IGY, but the American buildings were already unusable due to the build-up of ice around them. Australia built the first Casey Base, originally as "Repstat", referri ... [...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 ...

Law Dome
Law Dome is a large ice dome which rises to directly south of Cape Poinsett, Antarctica. The feature was roughly mapped by the United States Geological Survey from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47, and has been the subject of intensive glaciological and geophysical surveys by Australian National Antarctic Research Expeditions between 1962 and 1965. It was named by the Antarctic Names Committee of Australia for Phillip Law, Director of the Australian Antarctic Division from 1949 to 1966. The dome is bounded by the Totten Glacier to the east and the Vanderford Glacier Vanderford Glacier () is a glacier about 8 km (5 mi) wide flowing northwest into the southeast side of Vincennes Bay, slightly south of the Windmill Islands.

Wilkes Land
Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. Geography Wilkes Land fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. Subdivisions It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole: # Knox Land: 100°31' E to 109°16' E # Budd Land: 109°16' E to 115°33' E # Sabrina Land: 115°33' E to 122°05' E # Banzare Land: 122°05' E to 130°10' E # Clarie Land: (Wilkes Coast) 130° ...

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] |
Cape Nutt
Cape Nutt () is a mostly ice-covered cape with several rock outcrops at the extremity, forming the west side of the entrance to Vincennes Bay, Antarctica. The position of Cape Nutt correlates closely with the eastern end of "Knox's High Land" as charted as a coastal landfall in 1840 by the United States Exploring Expedition under Lieutenant Charles Wilkes. The cape was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–1947. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Commander David C. Nutt, U.S. Navy Reserve, research assistant in geography at Dartmouth College, who served as a marine biologist on U.S. Navy 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.

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] |
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 ...
