On today's episode, Dan takes the podcast out onto the Antarctic ice to find penguins, seals and the expedition scientists conducting experiments. He joins Dr Stefanie Arndt of the Alfred Wegener Institute as she researches climate change in the Weddell Sea's ice. Dan catches her just as she discovers some tiny and very rare snow crystals and her enthusiasm is infectious.

He also takes a trip back up to the ship's bridge to speak with Captain Knowledge Bengu, South Africa's first black ice pilot about his trailblazing career and the sheer might of the SA Agulhas II as he navigates through the heavy ice.
