摘要：The paper describes the ecohydrodynamic predictive model – the ecosystem module – for assessing the state of the Baltic marine environment and the Baltic ecosystem. The Baltic Sea model 3D CEMBS (the Coupled Ecosystem Model of the Baltic Sea) is based on the Community Earth System Model, which was adopted for the Baltic Sea as a coupled sea-ice-ecosystem model. The 3D CEMBS model uses: (i) hydrodynamic equations describing water movement, (ii) thermodynamic equations, (iii) equations describing the concentration distribution of chemical variables in the sea, and (iv) equations describing the exchange of matter between individual groups of organisms and their environment that make allowance for the kinetics of biochemical processes.
