Biogeochemical Modelling

Ecosystems are complex dynamic systems and the study of their functioning and evolution requires the development of dynamic biogeochemical models. Last two decades have seen a tremendous development in model based systems due to the increasing need of understanding marine ecosystems and their dynamic response to environmental stresses from pollution to climate change. Biogeochemical Modelling investigates the transport and cycling of elements within the ocean, primarily of climate-relevant biogeochemical tracer elements like carbon, oxygen, and nitrogen. Numerical models are applied 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.
