Mawson Suburb Sign

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 thousands of kilometres of previously unexplored regions, collected geological and botanical samples, and made important scientific observations. Mawson was the sole survivor of the three-man Far Eastern Party, which travelled across the Mertz and Ninnis Glaciers named after his two deceased companions. Their deaths forced him to travel alone for over a month to return to the expedition's main base.

Mawson was knighted in 1914 and during World War I worked with the British and Russian militaries. He returned to the University of Adelaide in 1919 and became a full professor in 1921, contributing much to Australian geology. He returned to the Antarctic as the leader of the British Australian and New Zealand Antarctic Research Expedition (1929–1931), which led to a territorial claim in the form of the Australian Antarctic Territory. Mawson is commemorated by numerous landmarks and from 1984 to 1996 appeared on the Australian $100 note.

Early life

Mawson was born on 5 May 1882 to Robert Ellis Mawson and Margaret Ann Moore. He was born in Shipley, West Riding of Yorkshire, but was less than two years old when his family emigrated to Australia and settled at Rooty Hill, now in the western suburbs of Sydney; Later he and his family moved to the inner-Sydney suburb of Glebe in 1893. He attended Forest Lodge Public School, Fort Street Model School and the University of Sydney, where he graduated in 1902 with a Bachelor of Engineering degree.

Early work

He was appointed geologist to an expedition to the New Hebrides (now Vanuatu) in 1903; his report, ''The Geology of the New Hebrides'', was one of the first major geological works of Melanesia. Also that year he published a geological paper on Mittagong, New South Wales. His major influences in his geological career were Professor Edgeworth David and Professor Archibald Liversidge. He then became a lecturer in petrology and mineralogy at the University of Adelaide in 1905. He identified and first described the mineral davidite.

''Nimrod'' Expedition

Mawson joined Ernest Shackleton's ''Nimrod'' Expedition (1907–1909) to the Antarctic, originally intending to stay for the duration of the ship's presence in the first summer. Instead both he and his mentor, Edgeworth David, stayed an extra year. In doing so they became, in the company of Alistair Mackay, the first to climb the summit of Mount Erebus and to trek to the South Magnetic Pole, which at that time was over land.

Australasian Antarctic Expedition

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 , with some winds approaching . 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 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:

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 will to move and wished only to remain in his sleeping bag. He began to deteriorate rapidly with diarrhoea and madness. On one occasion Mertz refused to believe he was suffering from frostbite and bit off the tip of his own little finger. This was soon followed by violent raging—Mawson had to sit on his companion's chest and hold down his arms to prevent him from damaging their tent. Mertz suffered further seizures before falling into a coma and dying on 8 January 1913.

It was unknown at the time that husky liver contains extremely high levels of vitamin A. It was also not known that such levels of vitamin A could cause liver damage to humans. With six dogs between them (with a liver on average weighing 1 kg), it is thought that the pair ingested enough liver to bring on a condition known as hypervitaminosis A. However, Mertz may have suffered more because he found the tough muscle tissue difficult to eat and therefore ate more of the liver than Mawson. While both men suffered, Mertz suffered more severely.

Mawson continued the final alone. During his return trip to the Main Base he fell through the lid of a crevasse, and was saved only by his sledge wedging itself into the ice above him. He managed to climb out using the harness attaching him to the sled.

When Mawson finally made it back to Cape Denison, the ship ''Aurora'' had left only a few hours before. It was recalled by wireless communication, only to have bad weather thwart the rescue effort. Mawson and six men who had remained behind to look for him wintered a second year until December 1913. In Mawson's book ''Home of the Blizzard'', he describes his experiences. His party, and those at the Western Base, had explored large areas of the Antarctic coast, describing its geology, biology and meteorology, and more closely defining the location of the South Magnetic Pole. In 1915, the Royal Geographical Society awarded him their Founder's Medal and in 1916 the American Geographical Society awarded him the David Livingstone Centenary Medal."The Cullum Geographical Medal"

The expedition was the subject of David Roberts' book ''Alone on the Ice: The Greatest Survival Story in the History of Exploration''.

''Home of the Blizzard''

In his book ''The Home of the Blizzard'', Mawson talked of "Herculean gusts" on 24 May 1912 which he learned afterwards "approached two hundred miles per hour". Mawson reported that the average wind speed for March was ; for April, ; and for May, . These katabatic winds can reach around and led Mawson to dub Cape Denison "the windiest place on Earth".

Later life

Mawson married Francisca Adriana (Paquita) Delprat (daughter of the metallurgist G. D. Delprat) on 31 March 1914 at Holy Trinity Church of England, Balaclava, Victoria. They had two daughters, Patricia and Jessica. Also in 1914, he was knighted, and was preoccupied with news of the Scott disaster until the outbreak of World War I. Mawson served in the war as a major in the British Ministry of Munitions. Returning to the University of Adelaide in 1919, he was promoted to the professorship of geology and mineralogy in 1921, and made a major contribution to Australian geology. He organised and led the joint British Australian and New Zealand Antarctic Research Expedition in 1929–31, which resulted in the formation of the Australian Antarctic Territory in 1936. He also spent much of his time researching the geology of the northern Flinders Ranges in South Australia.

Upon his retirement from teaching in 1952 he was made an emeritus professor of the University of Adelaide. He died at his Brighton home on 14 October 1958 from a cerebral haemorrhage. He was 76 years old. At the time of his death he had still not completed editorial work on all the papers resulting from his expedition, and this was completed by his eldest daughter, Patricia, only in 1975.
