Recreation of Douglas Mawson's Expedition
In April 2007 Tim Jarvis completed an expedition in Antarctica where he attempted to recreate the amazing expedition and human feat of Sir Douglas Mawson. Jarvis walked close to 500 km pulling a sleigh full of supplies, and living on almost the same rations as Mawson himself. Jarvis wanted to find out if the story of Mawson was physically possible. At the end of the expedition Jarvis said, "I haven't really done what Mawson did because I have doctors checking my situation, a film crew following me and a number of other safety precautions. Mawson had none of that."
The 2008 film of the expedition is available on DVD, "Mawson – Life and Death In Antarctica". The summary reads, "Combining the drama of Jarvis' contemporary adventure with chilling dramatic reconstructions, expert commentary and footage from the original expedition photographed by Frank Hurley, this is an extraordinary story of human survival." Tim is also author of a book of the same name (Melbourne University Press, 2008 (ISBN 978-0-522-85486-2).
In February 2013  Jarvis and five others successfully recreated Sir Ernest Shackleton's epic crossing of the Southern Ocean in the Alexandra Shackleton, a replica of the James Caird. Using the same materials, clothing, food and a Thomas Mercer chronometer as in the original voyage, Jarvis and the team sailed their replica James Caird to South Georgia, just as Shackleton did in 1916. The construction of the replica James Caird was started in June 2008 and was finished in 2010. It was officially launched on 18 March 2012 in Dorset, England. The Hon. Alexandra Shackleton is patron of the expedition.
A documentary of the epic crossing has been made and Shackleton Death or Glory went to air in the UK in September 2013 on Discovery UK and Australia in November 2013 on Special Broadcasting Service Australia; titled Chasing Shackleton for the USA market, it went to air in that region in January 2014 on the Public Broadcasting Service. 
A book authored by Tim titled Shackleton's Epic, Recreating the World's Greatest Journey of Survival, published by Harper Collins, went on sale in the UK and Australia in November 2013; titled Chasing Shackleton, Recreating the World's Greatest Journey of Survival for the USA market, it went on sale in January 2014 in the USA.
