In this paper, we present a model of ocean ecosystem to serve as a component of the global Earth System Model. The global ocean circulation model was forced by a fixed atmospheric influence following the CORE-II protocol. Arbitrary number of advected scalars allowed configuring biogeochemical block only balancing between detailed description and computational performance. A quasi-equilibrium model of an ecosystem in a seawater column, suitable for computationally complex climate calculations, was developed, taking into account nitrogen and/or phosphorus based nutrients, gravitational deposition of suspended organic matter and transformation of carbon compounds. A software interface was developed in order to seamlessly interact between geophysical and biogeochemical components of the model. Test calculations have been performed on the INM RAS computing cluster for 160 years, and the results are presented. It is shown that the calculated fields do not contradict typical distributions available in literature and open atlases. Seasonality in plankton production, dissolved organic carbon, CO2 concentrations and suspended matter is clearly observed.
