On this leg, I will serve as a member of the BioGeoChemistry team – we are principally interested in studying how climate relevant gasses cycle through the central Arctic’s ocean-ice-atmosphere system. Pictured here is myself, URI post-doc and Leg 4 BGC team lead Alessandra D’Angelo, and U. Gronigen post-doc Deborah Bozzato. The fourth and final member of our team, Falk Pätzold, was already onboard Polarstern having also participated in Leg 3.
