  • Summary

  • Flying low over ice in a timed dance with satellites. Digging 52m of ice cores out on the frozen sea. This is a team tackling Antarctica's sea ice question from every angle!
    In this group interview, teams from the DEFIANT* and CRYOVEX* projects talk about their epic campaign to 'ground-truth' the data collected from two important satellites that monitor Antarctic sea ice - ESA's CryoSat-2 and NASA's ICESat-2. This calibration work makes sure we know more about how the thickness of Antarctica's sea ice - helping us predict how climate changes will affect ocean circulation and ecology.
    Nadia Frontier is joined by guest host Matt Hughes, and members of the project team Andy Shepherd, Inès Otosaka, Sebastian Simonsen, Isobel Lawrence and Gaëlle Veyssière, and BAS' Head of Airborne Survey Technology, Carl Robinson.
