What’s the difference between glaciers and sea ice and why do we need to be studying sea ice to better understand climate change? In this episode, we speak to two experts who study sea ice in the arctic and antarctic respectively. Dr. Anja Frost and Dr. Sven Jacobsen share their concerns about the pressing issue of the Arctic’s vanishing sea ice, the need to understand the relationship between ocean waves and sea ice depletion, and how remote sensing techniques are improving our understanding of Arctic sea ice changes. Together, both Anja and Sven use their expertise to support ships travelling through the arctic. Their research helps to optimise ship navigation, reduce emissions, and improve the technologies and processes for studying sea ice using remote sensing.
