      The seaice in the Arctic is an important component in the climate system, and plays an important role by interacting with atmospheric circulation trough surface-albedo and energy-exchanges. To study the atmospheric response ...

    • Storms drive outgassing of CO2 in the subpolar Southern Ocean 

      Nicholson, S.-A.; Whitt, D. B.; Fer, Ilker; du Plessis, M; Lebéhot, A. D.; Swart, S.; Sutton, A. J.; Monteiro, M. S. (Journal article; Peer reviewed, 2022)
      The subpolar Southern Ocean is a critical region where CO2 outgassing influences the global mean air-sea CO2 flux (FCO2). However, the processes controlling the outgassing remain elusive. We show, using a multi-glider ...
