Trace Gas Biogeochemistry

The research interests of the working group can be described by the following points:

• 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

 

Projects

The Research Unit is involved in a variety of projects: 

•  (Biogeochemical processes and Air–sea exchange in the Sea-Surface microlayer)
•  (Eckernförde Bay, SW Baltic Sea)
•  (Concepts for reducing the impacts of anthropogenic pressures and uses on marine ecosystems and biodiversity)
•  (Exchange fluxes of climate-relevant trace gases off the Western Antarctic Peninsula)
•  (The MarinE MethanE and NiTrous Oxide database)
• SO305 BIOCAT-IIOE2 (Biogeochemistry/atmosphere processes in the Bay of Bengal: A contribution to the 2nd International Indian Ocean Expedition)
• Methane production in the ocean
• Nitrification rate measurements
