Soeren Ahmerkamp

My research focuses on the interaction between transport mechanisms and microbial processes, and their impact on the marine carbon and nitrogen cycle. My ap­proach com­bines nu­mer­ical mod­el­ling (Large-Eddy-Sim­u­la­tions, trans­port-re­ac­tion equa­tions, por­ous me­dia), field ob­ser­va­tions (de­vel­op­ment of the benthic ob­ser­vat­ory 'LanceALot') and labor­at­ory ex­per­i­ments (flow-through re­act­ors, mi­cro­fluidics, ima­ging tech­niques).

My main research areas are:

• Sub­tidal sandy sed­i­ments
• Biogeochemical processes on beaches
• Marine Aggregates
• Ciliary flows of stony corals
• Marine Aggregates

My research is part of the project Shallow Water Processes and Transitions to the Baltic Scale as well as the IOW research programme 2024-2033 "Perspectives of Coastal Seas".

I co-lead the Novo Nordisk-funded project MATIC: Multiscale Approach on Coral Resilience together with Klaus Koren (Aarhus University) and Lars Behrendt (Uppsala University).
