Applied Marine Biogeochemistry Groupat the Institute for Marine and Antarctic Studies
Marine biogeochemistry investigates element cycles in the ocean. We study the effects of deliberate changes in these element cycles, for example in the carbon cycle
We do field and laboratory research to improve our understanding of biogeochemical and ecological processes in the ocean
Currently, we focus on the assessment of ocean alkalinity enhancement (OAE) as a strategy for marine carbon dioxide removal (mCDR)
Ocean Alkalinity Enhancement
A coordinated pelagic impact intercomparison project for OAE research.
Field Study 2026
A coastal field programme tracking OAE effects on seagrass-bed plots.
Applied Marine Biogeochemistry Group
Researchers across marine chemistry, ecology, modelling, and field operations.
OAE field study 2026
Follow the 2026 field programme from scouting and plot setup to sampling and recovery.
