Preparations are underway for an Antarctic mission in a lifeboat.<br/> <br />Australian environmental scientist Tim Jarvis is attempting to retrace the daring voyage of explorer Ernest Shackleton in nothing but this 22-and-a-half-foot boat.<br/> <br />After Shackleton's ship got trapped in ice on a 1914 mission to the South Pole, he and several crew members rowed a similar boat 800 miles to get help from a whaling station.<br/> <br />Nearly a century later, a British and Australian team will make the same trip from Elephant Island to South Georgia, but this time for an environmental cause.<br/> <br />(SOUNDBITE)(English) EXPLORER, TIM JARVIS SAYING:<br/> <br />"Well, Shackleton was trying to save his men from the Antarctic and we're now trying to save Antarctica from man and that's got to be the ultimate irony unfortunately."<br/> <br />They will only use the gear available to Shackleton 100 years ago, except for the camera equipment to film their journey.<br/> <br />(SOUNDBITE)(English) EXPLORER, TIM JARVIS SAYING:<br/> <br />"And so it's amazing to think that a hundred years, with all of our modern thinking we've ended up with exactly what Shackleton had but yes it's still a very tippy, very unsafe boat."<br/> <br />The team plans to set sail from South America in January.
