USS Glacier (AGB-4)
USS ''Glacier'' (AGB-4) (later USCGC ''Glacier'' (WAG/WAGB-4)) was a U.S. Navy, then U.S. Coast Guard icebreaker which served in the first through fifteenth Operation Deep Freeze expeditions. ''Glacier'' was the first icebreaker to make her way through the frozen Bellingshausen Sea, and most of the topography in the area is named for her crew members. When built, ''Glacier'' had the largest capacity single armature DC motors ever installed on a ship. ''Glacier'' was capable of breaking ice up to thick, and of continuous breaking of thick ice at . Named for Glacier Bay, Alaska, USS ''Glacier'' was launched on 27 August 1954 at Ingalls Shipbuilding Corp., Pascagoula, Mississippi, sponsored by Mrs. Roscoe F. Good; and commissioned on 27 May 1955, CDR. E.H. Mayer USN, Commanding. ''Glacier'' is the only icebreaker built in the ''Glacier'' class, and was in U.S. Navy service for 11 years, and U.S. Coast Guard service for 21 years. Construction ''Glacier'' was essentially an im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bellingshausen Sea
The Bellingshausen Sea is an area along the west side of the Antarctic Peninsula between 57°18'W and 102°20'W, west of Alexander Island, east of Cape Flying Fish on Thurston Island, and south of Peter I Island (there the southern ''Vostokkysten''). In the south are, from west to east, Eights Coast, Bryan Coast and English Coast (west part) of West Antarctica. To the west of Cape Flying Fish it joins the Amundsen Sea. Bellingshausen Sea has an area of and reaches a maximum depth of . It contains the undersea plain Bellingshausen Plain. It takes its name from Admiral Thaddeus Bellingshausen, who explored in the area in 1821. In the late Pliocene Epoch, about 2.15 million years ago, the Eltanin asteroid (about 1-4 km in diameter) impacted at the edge of the Bellingshausen sea (at the South Pacific Ocean South is one of the cardinal directions or compass points.

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) 1 ...

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] |
Weddell Sea
The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf. The sea is contained within the two overlapping Antarctic territorial claims of Argentine Antarctica, the British Antarctic Territory, and also resides partially within the Antarctic Chilean Territory. At its widest the sea is around across, and its area is around . Various ice shelves, including the Filchner-Ronne Ice Shelf, fringe the Weddell sea. Some of the ice shelves on the east side of the Antarctic Peninsula, which formerly covered roughly of the Weddell Sea, had completely disappeared by 2002. The Weddell Sea has been deemed b ...

McMurdo Sound
McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. Boundary and Extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and is t ...

Little America (exploration Base)
Little America was a series of Antarctic exploration bases from 1929 to 1958, located on the Ross Ice Shelf, south of the Bay of Whales. The coordinates are approximate. Little America I The first base in the series was established in January 1929 by Richard Byrd, and was abandoned in 1930. This was where the film ''With Byrd at the South Pole'' (1930), about Byrd's trip to the South Pole, was filmed. Little America II Little America II was established in 1934, some above the site of the original base, with some of the original base accessed via tunnel. This base was briefly set adrift in 1934, but the iceberg fused to the main glacier. During the 1934–1935 expedition, many souvenir letters were sent from Little America, using a commemorative postage stamp issued by the U.S. government. The souvenir cancellation operations were conducted under extremely difficult conditions. Little America established the first successful radio broadcasting from Antarctica, making ...

Richard Evelyn Byrd
Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer. He was a recipient of the Medal of Honor, the highest honor for valor given by the United States, and was a pioneering American aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. Byrd said that his expeditions had been the first to reach both the North Pole and the South Pole by air. His belief to have reached the North Pole is disputed. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Family Ancestry Byrd was born in Winchester, Virginia, the son of Esther Bolling (Flood) and Richard Evelyn Byrd Sr. He was a descendant of one of the First Families of Virginia. His ancestors include planter John Rolfe and his wife Pocahontas, William Byrd II of Westover P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flagship
A flagship is a vessel used by the commanding officer of a group of naval ships, characteristically a flag officer entitled by custom to fly a distinguishing flag. Used more loosely, it is the lead ship in a fleet of vessels, typically the first, largest, fastest, most heavily armed, or best known. Over the years, the term "flagship" has become a metaphor used in industries such as broadcasting, automobiles, education, technology, airlines, and retail to refer to their highest profile or most expensive products and locations. Naval use In common naval use, the term ''flagship'' is fundamentally a temporary designation; the flagship is wherever the admiral's flag is being flown. However, admirals have always needed additional facilities, including a meeting room large enough to hold all the captains of the fleet and a place for the admiral's staff to make plans and draw up orders. Historically, only larger ships could accommodate such requirements. The term was also used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumblehome
Tumblehome is a term describing a hull which grows narrower above the waterline than its beam. The opposite of tumblehome is flare. A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves. The term is also applied to automobile design, where a vehicle's sides taper inward as they go up. This includes a roof tapering in, and curved window glass. Origins Tumblehome was common on wooden warships for centuries. It allowed for maximizing a vessel's beam and creating a low center of gravity (by decreasing mass above the waterline), both tending to maximize stability. In the era of oared combat ships it was quite common, placing the oar ports as far abeam as possible, allowing maximum possible manpower to be brought to bear. Inward-sloping sides made it more difficult to board by a vessel by force, as the ships would come to contact at their widest points, with the decks some distance apart. ...
