Iceberg B-9
Iceberg B-9 was an iceberg that calved from Antarctica in 1987. It measured long and wide; it had a total area of , and is one of the longest icebergs ever recorded. This calving took place immediately east of the future calving site of Iceberg B-15; it carried away Little America V which had been closed in December 1959. Starting in October 1987, Iceberg B-9 drifted for 22 months, covering on its journey. Initially, B-9 moved northwest for seven months, before being drawn southward by a subsurface current that eventually led to its colliding with the Ross Ice Shelf in August 1988. It then made a radius gyre before resuming its northwest drift. It moved at an average speed of per day over the continental shelf, as measured by NOAA-10 and DMSP satellite positions, and by the ARGOS data buoy positions. In early August 1989, B-9 broke into three large pieces north of Cape Adare. These pieces were designated as B-9A, , B-9B, , and B-9C, . B-9A drifted east and was located abou ...

Mawson's Huts
Mawson's Huts are the collection of buildings located at Cape Denison, Commonwealth Bay, in the far eastern sector of the Australian Antarctic Territory, some 3000 km south of Hobart. The buildings were erected and occupied by the Australasian Antarctic Expedition (AAE) of 1911-1914, led by geologist and explorer Sir Douglas Mawson. Mawson's Huts are rare as one of just six surviving sites from the Heroic Era of Antarctic exploration. The Australasian Antarctic Expedition was the only Heroic Era expedition organised, manned and supported primarily by Australians. The huts included a Magnetometer#Survey magnetometers, magnetograph hut, used to measure variations in the south magnetic pole; an absolute magnetic hut, which was used as a reference point for studies in the magnetograph hut; and the transit hut, an astronomical observatory. The most important building at the site is the winter living quarters, known as "Mawson's Hut". This pyramid-roofed hut was home to the eigh ...

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] |
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 ...

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] |
George V Coast
George V Coast () is that portion of the coast of Antarctica lying between Point Alden, at 148°2′E, and Cape Hudson, at 153°45′E. Portions of this coast were sighted by the US Exploring Expedition in 1840. It was explored by members of the Main Base party of the Australasian Antarctic Expedition (1911–14) under Douglas Mawson who named this feature for King George V of the United Kingdom. The segment of land between these lines of longitude is referred to as George V Land. Mertz Glacier is located in this area.

Mertz Glacier
Mertz Glacier () is a heavily crevassed glacier in George V Coast of East Antarctica. It is the source of a glacial prominence that historically has extended northward into the Southern Ocean, the ''Mertz Glacial Tongue''. It is named in honor of the Swiss explorer Xavier Mertz. The Mertz-Ninnis Valley () is an undersea valley named in association with the Mertz Glacier and the Ninnis Glacier. Geography Mertz Glacier is about 45 miles (72 km) long and averaging 20 miles (32 km) wide. It reaches the sea at the head of a 60 km fjord where it continues as a large glacier tongue out between Cape De la Motte/ Buchanan Bay on the West, and Cape Hurley/ Fisher Bay on the east, into the Southern Ocean. The Mertz Glacier Tongue () is about 50 miles (80 km) long in total hence it protrudes about 20–25 km out into the Ocean. It is roughly 25 miles (40 km) wide. The Glacier delivers about 10 to 12 Gigatons of ice per year to the fjord and the Tongue advan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Cape Adare
Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica. Description Marking the north end of Borchgrevink Coast and the west end of Pennell Coast, the cape separates the Ross Sea to the east from the Southern Ocean to the west, and is backed by the high Admiralty Mountains. Cape Adare was an important landing site and base camp during early Antarctic exploration. Off the coast to the northeast are the Adare Seamounts and the Adare Trough. History Captain James Ross discovered Cape Adare in January 1841 and named it after his friend the Viscount Adare (the title is derived from Adare, Ireland). In January 1895, Norwegian explorers Henrik Bull and Carsten Borchgrevink from the ship '' Antarctic'' landed at Cape Adare as the first documented landing on Antarctica, collecting geological specimens. Borchgrevink returned to the cape leading his own expedition i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
