Research Interests


     - formation and spreading of intermediate and deep water masses
       in the subpolar North Atlantic
     - formation of Antarctic Intermediate Water (AAIW) in the South Atlantic
       and changes in its uptake of anthropogenic carbon
     - formation and detection of eddies, fronts, and meanders
       and their role for the lateral exchange of water masses
     - water export and variability-driving processes in Flemish Pass, western North Atlantic
     - short-/long-term variability of water mass properties
     - measurement and analysis of anthropogenic tracers (e.g. CFCs, SF6)
     - analysis of ship- and satellite-based observational data
