context_page_description: Sir Douglas Mawson OBE FRS FAA 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, 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. The expedition explored thousands of kilometres of previously unexplored regions, collected geological and botanical samples, and made important scientific observations.
context_section_description: Mawson turned down an invitation to join Robert Falcon Scott's Terra Nova Expedition in 1910; Australian geologist Griffith Taylor went with Scott instead. Mawson chose to lead his own expedition, the Australasian Antarctic Expedition, to King George V Land and Adelie Land, the sector of the Antarctic continent immediately south of Australia, which at the time was almost entirely unexplored.
  The objectives were to carry out geographical exploration and scientific studies, including a visit to the South Magnetic Pole.
  Mawson raised the necessary funds in a year, from British and Australian governments, and from commercial backers interested in mining and whaling.
  The expedition, using the ship SY Aurora commanded by Captain John King Davis, departed from Hobart on 2 December 1911, landed at Cape Denison (named after Hugh Denison, a major backer of the expedition) on Commonwealth Bay on 8 January 1912, and established the Main Base. A second camp was located to the west on the ice shelf in Queen Mary Land. Cape Denison proved to be unrelentingly windy; the average wind speed for the entire year was about 50 mph (80 km/h), with some winds approaching 200 mph (320 km/h). They built a hut on the rocky cape and wintered through nearly constant blizzards. Mawson wanted to do aerial exploration and brought the first aeroplane to Antarctica. The aircraft, a Vickers R.E.P. Type Monoplane, was to be flown by Francis Howard Bickerton. When it was damaged in Australia shortly before the expedition departed, plans were changed so it was to be used only as a tractor on skis. However, the engine did not operate well in the cold, and it was removed and returned to Vickers in England. The aircraft fuselage itself was abandoned. On 1 January 2009, fragments of it were rediscovered by the Mawson's Huts Foundation, which is restoring the original huts.
  Mawson's exploration program was carried out by five parties from the Main Base and two from the Western Base. Mawson himself was part of a three-man sledging team, the Far Eastern Party, with Xavier Mertz and Lieutenant Belgrave Ninnis, who headed east on 10 November 1912, to survey King George V Land. After five weeks of excellent progress mapping the coastline and collecting geological samples, the party was crossing the Ninnis Glacier 480 km east of the main base. Mertz was skiing and Mawson was on his sled with his weight dispersed, but Ninnis was jogging beside the second sled. Ninnis fell through a crevasse, and his body weight is likely to have breached the snow bridge covering it. The six best dogs, most of the party's rations, their tent, and other essential supplies disappeared into the massive crevasse. Mertz and Mawson spotted one dead and one injured dog on a ledge 165 ft below them, but Ninnis was never seen again.
  After a brief service, Mawson and Mertz turned back immediately. They had one week's provisions for two men and no dog food but plenty of fuel and a primus. They sledged for 27 hours continuously to obtain a spare tent cover they had left behind, for which they improvised a frame from skis and a theodolite. Their lack of provisions forced them to use their remaining sled dogs to feed the other dogs and themselves:
  Their meat was stringy, tough and without a vestige of fat. For a change we sometimes chopped it up finely, mixed it with a little pemmican, and brought all to the boil in a large pot of water. We were exceedingly hungry, but there was nothing to satisfy our appetites. Only a few ounces were used of the stock of ordinary food, to which was added a portion of dog's meat, never large, for each animal yielded so very little, and the major part was fed to the surviving dogs. They crunched the bones and ate the skin, until nothing remained.
  There was a quick deterioration in the men's physical condition during this journey. Both men suffered dizziness; nausea; abdominal pain; irrationality; mucosal fissuring; skin, hair, and nail loss; and the yellowing of eyes and skin. Later Mawson noticed a dramatic change in his travelling companion. Mertz seemed to lose the
