In this episode she reveals the latest scientific insights into icebergs. From side-scanning sonar that scrutinises the edge of glaciers where icebergs are born, to satellite images that show how icebergs create hotspots for life and eyewitness pictures that give us a unique glimpse of how they transform over time, we can now capture on camera the mysteries of icebergs – and how their lifecycle is intricately linked to our changing planet.
