Science in Antarctica

Iceberg (c) Uwe Kils @wikipedia

As winter approaches, we take a trip down south to look at some of the cool research going on in Antarctica. Dr Jane Francis from Leeds University talks about six-foot penguins and a time when Antarctica was warm and ice-free, Kate Hendry from the University of Oxford describes what it's like to work in Antarctica today, and Derek and Dave bring a welcome injection of heat as they find out how hand warmers work. We then dive into the waters around Antarctica with Dr Povl Abrahamsen from the British Antarctic Survey, who uses automated subs to look under the ice sheets and find out how they're changing, and Dr Mike Fedak from the University of St. Andrews describes how his team have attached data collection instruments to the fur of elephant seals to explore completely unchartered depths of the Southern Ocean.

  • How can beer freeze immediately?

    Sometimes when I put my beer (330mL glass bottle) in the deep freeze to rapidly chill it, I can take it out and it's still liquid. If I then leave it for a few minutes on the side and come back to drink it, it goes all icy. Why is this? Sur...
