Marine Biogeochemistry, Geochemical element cycles, Deep Biosphere

Dr. Wehrmann’s research focuses on several aspects of (bio)geochemical element cycling in marine systems, ranging from subseafloor sediments to glacially influenced fjords. She is specifically interested in the drivers of early diagenetic processes and the connections between different element cycles, e.g., the carbon, sulfur and iron cycles. She also investigates the response of microbially mediated processes in the deep sub-seafloor biosphere to changing (paleo)environmental conditions over different temporal and spatial scales. Her work combines classical inorganic geochemical techniques with stable isotope analyses and the application of radiotracer methods.
