The
Marine Biogeochemistry Section conducts basic research in diverse areas of
aquatic and sediment biogeochemistry.
Following projects are currently active:
- Biogeochemical
kinetics of microbial ferruginous smectite reduction
- Microbially mediated flocculation of aquatic suspended
particles
- Microbially induced
smectite-to-illite transformation
- Microbial manganese
cycling
- Computational
early diagenetic modeling in dynamic sediments
