Douglas Mawson - Australasian Antarctic Expedition

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.

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 for 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. 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 snow-covered crevasse, and his body weight is likely to have breached the lid. 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 50 m 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 three 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 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 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 is poisonous 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 . It is of interest to note that in Eskimo tradition the dog's liver is never eaten. While both men suffered Mertz suffered chronically. Another theory has suggested the reason he suffered worse was because he had been a vegetarian. A 2005 article in The Medical Journal of Australia by Denise Carrington-Smith, noting that Mertz was essentially a vegetarian, suggested that the sudden change to a predominantly meat diet could have triggered Mertz's illness. Combined with "the psychological stresses related to the death of a close friend and the deaths of the dogs he had cared for, as well as the need to kill and eat his remaining dogs," this may have killed Mertz.

Mawson continued the final 100 miles 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 was forced 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 1916, the American Geographical Society awarded Mawson the David Livingstone Centenary Medal.
