Cape Hordern
Cape Hordern is an ice-free cape, overlain by morainic drift, at the northwest end of the Bunger Hills in Antarctica. It was probably sighted from Watson Bluff () by A.L. Kennedy and other members of the Western Base Party of the Australasian Antarctic Expedition under Mawson, 1911–14, who charted the west wall of what appeared to be two small islands lying north of Cape Hoadley in about 100°35′E. It was named "Hordern Island" by Mawson for Sir Samuel Hordern of Sydney, a patron of the expedition. It was renamed Cape Hordern by the Advisory Committee on Antarctic Names (US-ACAN) following correlation of Kennedy's map with the US-ACAN map of 1955 compiled from aerial photographs taken by U.S. Navy 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.

Morainic Drift
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Bunger Hills
Bunger Hills, also known as Bunger Lakes or Bunger Oasis, is a coastal range on the Knox Coast in Wilkes Land in Antarctica, consisting of a group of moderately low, rounded coastal hills, overlain by morainic drift and notably ice free throughout the year, lying south of the Highjump Archipelago. The reasoning behind the minute amount of ice in the area is still relatively unknown and remains under intense debate amongst scientists today. The Bunger Hills are located with its center at , stretching from 65°58'S to 66°20'S and from 100°20'E to 101°28'E. The Bunger Hills are marked by numerous melt ponds and are nearly bisected by an east-west trending Algae Lake (also known as Lake Figurnoye). Mapped from air photos taken by the United States Navy Operation Highjump (1946-1947) and named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Commander David E.

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] |

Western Base Party
The Western Base Party was a successful exploration party of the Australasian Antarctic Expedition. The eight-man Western Party was deposited by the SY ''Aurora'' on the Shackleton Ice Shelf at Queen Mary Land. The leader of the team was Frank Wild and the party included the geologist Charles Hoadley. The party established the Queen Mary Land Station. An early setback was the destruction of the radio mast in the first blizzard. Severe weather impeded activities as did dangerous crevices. The team sent an expedition into Kaiser Wilhelm II Land. The party had no supplies for a second winter. The Western Base Party was collected on February 23, 1913 by the ''Aurora'', with no loss of life. Discoveries The Western Base Party made a number of discoveries including; * Adams Island * Bay of Winds * Cape Penck * Cape Hoadley * Cape Hordern * Denman Glacier * Pobeda Ice Island * Farr Bay (discovered in November 1912) * Henderson Island (discovered in August 1912) * Hippo Is ...

Australasian Antarctic Expedition
The Australasian Antarctic Expedition was a 1911–1914 expedition headed by Douglas Mawson that explored the largely uncharted Antarctic coast due south of Australia. Mawson had been inspired to lead his own venture by his experiences on Ernest Shackleton's ''Nimrod'' expedition in 1907–1909. During its time in Antarctica, the expedition's sledging parties covered around of unexplored territory, while its ship, , navigated of unmapped coastline. Scientific activities included meteorological measurements, magnetic observations, an expansive oceanographic program, and the collection of many biological and geological samples, including the discovery of the first meteorite found in Antarctica. The expedition was the first to establish and maintain wireless contact between Antarctica and Australia. Another planned innovation – the use of an aircraft – was thwarted by an accident before the expedition sailed. The plane's fuselage was adapted to form a motorised sledge or "air ...

Mawson
Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer, and academic. Along with Roald Amundsen, Robert Falcon Scott, and Sir Ernest Shackleton, he was a key expedition leader during the Heroic Age of Antarctic Exploration. Mawson was born in England and came to Australia as an infant. He completed degrees in mining engineering and geology at the University of Sydney. In 1905 he was made a lecturer in petrology and mineralogy at the University of Adelaide. Mawson's first experience in the Antarctic came as a member of Shackleton's ''Nimrod'' Expedition (1907–1909), alongside his mentor Edgeworth David. They were part of the expedition's northern party, which became the first to attain the South Magnetic Pole and to climb Mount Erebus. After his participation in Shackleton's expedition, Mawson became the principal instigator of the Australasian Antarctic Expedition (1911–1914). The expedition explored thousa ...

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] |
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.
