BBC reporter takes Antarctic dip

Earlier this year, BBC science reporter Victoria Gill followed a team of scientists on an Antarctic expedition to set up remote, automated cameras in penguin colonies.

The researchers worked from a tour ship, which offered passengers the opportunity to "plunge" into the almost freezing ocean off the Antarctic coast.

Wearing a waterproof camera, Victoria took the plunge.
