Step out on the sea ice just outside New Zealand’s Scott Base with researchers studying the physics of its annual cycle. Each year a massive patch of ocean around Antarctica freezes and then melts again come summer – Antarctica’s heartbeat. In winter, the ice effectively more than doubles the size of this already massive continent, and it plays a huge role in controlling our planet’s climate.
Guests:
- Dr Inga Smith, University of Otago
- Antonia Radlwimmer, University of Otago
- Professor Wolfgang Rack, University of Canterbury

- Listen to Physics on Ice from 2021 with Emeritus Professor Pat Langhorne and Dr Inga Smith.

This series was made with travel support from the Antarctica New Zealand Community Engagement Programme.
