i was in the falklands in 94 for 4 months from feb to june at the southern tip of west falkland(autumn begining of winter), i am not an "antarctic explorer" and didn't take any thing other than your standard thermals but managed to survive ! ok it wasn't out to sea and a long way south (i.e colder) than des's drilling area but i (and the locals) must deserve a medal of some sort if you listen to biswells description of the weather in the area ! move over sir ranulph fiennes ;-D
