5.9 On Thin Ice: How Data and Models Reveal Antarctic Sea-Ice Thickness/ w Shreya Trivedi, Sujai & Touqeer

Welcome to the last episode of this season! We dive beneath the flat maps of Antarctic sea ice and ask a deeper question: how thick is the ice—and why does that matter? As Antarctic sea ice reaches record lows, we explore why ice extent alone cannot capture the real state of the system. Joined by cryosphere scientist Dr. Shreya Trivedi, we unpack how satellites use radar and lasers to estimate sea-ice thickness, why winter remains the toughest season to observe, and how ice volume shapes climate, weather, ocean circulation, and polar ecosystems. A clear, engaging conversation on why thickness is the missing dimension in understanding Antarctic change.

The guest for this episode were:

Dr. Shreya Trivedi, Postdoctoral Program Fellow, at the Goddard Space Flight Centre, NASA (US)
