Last week, a helicopter rescued passengers who had been stuck on a research vessel that was trapped in ice as part of the Australasian Antarctic Expedition. The expedition has faced some unwarranted criticism, writes Chris Turney, a professor at the University of New South Wales who led the trip. The expedition was carried out in the spirit of an earlier voyage by Sir Douglas Mawson, and it was scientifically valuable, Turney writes. "The AAE is not a jolly tourist trip as some have claimed, nor is it a re-enactment," he writes. "The AAE is inspired by Mawson but is primarily a science expedition; it will be judged by its peer-reviewed publications."
