David Island
David Island () is an ice-covered island, long and wide, marked by rock exposures along its north and east sides, lying off Davis Peninsula in the Shackleton Ice Shelf in Antarctica. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition (AAE) under Douglas Mawson. Mawson named the island for Edgeworth David Sir Tannatt William Edgeworth David (28 January 1858 – 28 August 1934) was a Welsh Australian geologist and Antarctic explorer. A household name in his lifetime, David's most significant achievements were discovering the major Hunter V ..., a member of the AAE Advisory Committee.

Shackleton Ice Shelf
Shackleton Ice Shelf is an extensive ice shelf fronting the coast of East Antarctica from 95° E to 105° E. It extends for an along-shore distance of about , projecting seaward about in the western portion and in the east. It occupies an area of . It is part of Mawson Sea and separates the Queen Mary Coast to the west from the Knox Coast of Wilkes Land to the east. Discovery and naming The existence of this ice shelf was first made known by the USEE under Charles Wilkes who mapped a portion of it from the ''Vincennes'' in February 1840. It was explored by the Australian Antarctic Expedition under Douglas Mawson (1911–14) who named it for Sir Ernest Shackleton. The extent of the ice shelf was mapped in greater detail in 1955, using aerial photography obtained by US Navy Operation Highjump, 1946–47. Further mapping by the Soviet Expedition of 1956 showed the portion eastward of Scott Glacier to be a part of this ice shelf. Important Bird Area A 500 ha ...

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 ...

Douglas 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 thousand ...

Edgeworth David
Sir Tannatt William Edgeworth David (28 January 1858 – 28 August 1934) was a Welsh Australian geologist and Antarctic explorer. A household name in his lifetime, David's most significant achievements were discovering the major Hunter Valley coalfield in New South Wales and leading the first expedition to reach the South Magnetic Pole. He also served with distinction in World War I. Early life David was born on 28 January 1858, in St. Fagans near Cardiff, Wales, the eldest son of the Rev. William David, a fellow of Jesus College, Oxford, a classical scholar and naturalist and his wife Margaret Harriette (née Thomson). His mother's cousin, William A. E. Ussher of the Geological Survey, first interested David in what was to be his life work. At the age of 12, David went to Magdalen College School, Oxford in 1870. In 1876 he gained a classical scholarship to New College, Oxford. While there he was lectured by the famous John Ruskin and William Spooner. In 1878 he suff ...

The Baldwin Rocks () are a group of rock outcrops about northwest of Watson Bluff on the north side of David Island. They were charted by the Australasian Antarctic Expedition, 1911–14, under Mawson, and named by him for Joseph M.
