Keep In A Cool Place: The First Winter at Vanda Station, Antarctica (PHOTO: Supplied)
Temperatures dropping to minus 57 degrees, 16 weeks of darkness, isolation stretching to eight months and logistical challenges...
That's what five scientists faced during the first winter at New Zealand's Vanda Station in Antarctica in 1969.
On the shore of Lake Vanda in the Dry Valleys, the group were investigating the strangely snowless landscape, and why the lake, while covered in metres of ice, had waters reaching 25 degrees at the bottom of the lake.
It was a remarkable expedition, not just for its scientific contributions, but for the limited supplies and extreme conditions they endured.
Kathryn speaks to two of the group; Al Riordan and Simon Cutfield, who have written a book of their experience; Keep in a Cool Place: The First Winter at Vanda Station, Antarctica.
