Hannam Islands
The Hannam Islands are three small islands lying in the eastern part of Commonwealth Bay, Antarctica, midway between Cape Denison and Cape Gray. They were discovered by the Australasian Antarctic Expedition (1911–14) under 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 ..., who named them for Walter H. Hannam, a wireless telegrapher with the expedition.

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] |

Commonwealth Bay
Commonwealth Bay is an open bay about 48 km (30 mi) wide at the entrance between Point Alden and Cape Gray in Antarctica. It was discovered in 1912 by the Australasian Antarctic Expedition under Douglas Mawson, who established the main base of the expedition at Cape Denison at the head of the bay. Named by Australasian Antarctic Expedition after the Commonwealth of Australia. Katabatic Wind The bay is listed in both the ''Guinness Book of World Records'' and the Eighth Edition of the ''National Geographic Atlas'' as the windiest place on Earth with winds regularly exceeding per hour and an average annual wind speed of per hour. Storms are caused by katabatic wind, a concentrated flow of cold air moving along the steep surface of the ice shield towards the sea. The air flow is accelerated by the increasing gradient of the surface of ice and the cliff monolith at Cape Denison. In the summer there are periods of relative calm but during winter storms are especially st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Denison
Cape Denison is a rocky point at the head of Commonwealth Bay in George V Land, Antarctica. It was discovered in 1912 by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who named it for Sir Hugh Denison of Sydney, a patron of the expedition. The cape was the site of the expedition's main base. Called by Mawson "the windiest place on Earth", the site experiences fierce katabatic winds. Historic site The site, including Mawson's Huts, Boat Harbour and the historic artefacts contained within its waters, has been designated a Historic Site or Monument (HSM 77), following a proposal by Australia to the Antarctic Treaty Consultative Meeting. First aeroplane in Antarctica The Air-tractor sledge, the first aeroplane to be brought to Antarctica (in 1912) was stationed at Cape Denison, although it never took to the air on the continent because it was damaged before being shipped there. The aircraft, a Vickers R.E.P. Type Monoplane (the first aircraft type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Gray
Cape Gray is a rocky cape which forms the east side of the entrance to Commonwealth Bay, part of the George V Coast of Antarctica. The cape is actually a small rocky island which is joined to the icecap of the mainland by an ice ramp. It was discovered by the Australasian Antarctic Expedition (1911–14) under 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 ..., who named it for Percival Gray, second officer on the expedition ship ''Aurora''.

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 ...
