MASTER THESIS OPPORTUNITY
Helmholtz Centre for Ocean Research Kiel (Kristin Bergauer Lab) in collaboration with the Microbial Oceanography Unit of the University of Vienna (Gerhard J. Herndl)
Examining whether and how temperature and oxygen changes in the Baltic Sea influence how micronutrients are used in marine microbes and what the consequences of those changes might be for biogeochemical cycles.
