Marine Biogeochemistry

Biogeochemical Modelling

The research unit Biogeochemical Modelling investigates the transport and cycling of elements within the ocean, primarily of climate-relevant biogeochemical tracers like carbon, oxygen, and nitrogen. We are concerned with the assessment of impacts of past and likely future climate variations on biogeochemical cycles and their feedbacks in the Earth system. For our research we apply numerical models that differ in their complexity, from simple process models, advanced optimality- and trait-based physio-ecological models, to coupled biogeochemistry-circulation models of the World Ocean. Data assimilation and parameter optimisation methods are used for rigorous model evaluations.

Our interdisciplinary research contributes to national- and international science programmes. We coordinate the DFG-funded Collaborative Research Centre „Climate Biogeochemistry Interactions in the Tropical Ocean“ (SFB 754) and the Priority Program „Climate Engineering: Risks, Challenges, Opportunities?“ (SPP 1689). The team consists of scientists and students interested in marine biology and ecology, chemistry, physics and in the general impacts of global change. We closely collaborate with other theoretical and observational groups of GEOMAR, as well as with mathematicians and computer scientists, e.g. of the Excellence Cluster "The Future Ocean" at Christian-Albrechts-Universität zu Kiel.
