Coupled physical biogeochemical model

Embedded in the circulation model, it provides a coupled physical-biogeochemical model of the Baltic Sea ecosystem as an example application. Several applications of the model system are discussed, covering process studies, such as currents in the western Baltic, river plumes, and sediment transport, but also long-term simulations of the ecosystem dynamics. 

We conclude this section with a brief overview of some of the 3-dimensional, dynamic coupled physical-biological models that were developed in the 1990s. There is a historic spht in the practice of ocean biogeochemical modefing, i.e., the field has been divided into large-scale global box and later circulation models with...

When properly formulated, the combination of ocean process tracers and numerical models provides powerful tools for studying ocean biogeochemistry. At their most basic level, models are simply a mathematical statement quantifying the rates of the essential physical and biogeochemical processes. For example, advection-diffusion models are structured around coupled sets of differential equations ...
