Research Interests

  • Open ocean and coastal biogeochemistry of nitrogen, carbon and sulphur
  • Special focus on upwelling regions/OMZ, the Arctic Sea and the Baltic Sea
  • Cycling and emissions of oceanic trace gases (N2O, NO, CH4, CO, DMS)
  • Development of underwater trace gas sensors
  • Measurements of short-lived intermediates of the nitrogen and sulphur cycles (NH2OH, NO, DMSP and DMSO)
  • Biogeochemical time-series observations
  • 15N isotope signature of dissolved nitrate


  • Head of research group 'Trace Gas Biogeochemistry'
