Marine Biogeochemistry

The research unit Biogeochemical Modelling investigates the transport of climate-relevant biogeochemical tracers (primarily carbon, oxygen and nitrogen) within the ocean and across its boundaries with the atmosphere and the sediment. Main tools are numerical models, ranging from conceptually simple process models to complex coupled ecosystem-circulation models of the World Ocean.

Current research emphasis is on the development of new marine ecosystem models, using data assimilation methods for model calibration and evaluation, on the quantification of physical controls on biological production, and on the assessment of impacts of past and likely future climate change on relevant biogeochemical cycles.

Our research unit works interdisciplinary in national and international programmes and consists of researchers interested in marine biology, chemistry and physics. We closely collaborate with other theoretical and observational groups of GEOMAR, as well as with mathematicians and computer scientists, e.g. within the excellence cluster "The Future Ocean".
