The Green JASMINE complex is designed to produce consistent data on the thermo-hydrodynamical and biogeochemical parameters of the White Sea, as well as to assess the matter fluxes within the sea and in the areas adjacent to the Barents Sea. The JASMINE model serves as the Hydrodynamical block and is based on the finite element model of the Arctic Ocean (FEMAO). It is coupled with the biogeochemical block, which is the BFM model maintained and developed by the BFM Consortium. BFM uses the stoichiometric approach for description of the state of ecosystem: variables are concentrations of elements or substances in different functional groups, e. g., diatoms, large phytoplankton,

cyanobacteria, pelagic bacteria, heterotrophic flagellates, dissolved organic or inorganic matter, including oxygen and hydrogen sulfide, etc. The total number of variables is about 50: cycles of carbon, nitrogen, phosphorus, silicium are described, as well as production of chlorophyll-a by autotrophic plankton. Thermodynamical fields have been shown to be well reproduced by the model. The behaviour of chlorophyll and primary production also corresponds to the real pattern. The developed software complex Green JASMINE allows solving important problems concerning ecological systems of the White Sea. It is able to simulate the distribution of water temperature and salinity, ice cover, and ecological tracers depending on climate change scenarios. There is a functioning passive tracer advection block which can be useful for simulating ecological disasters. The complex is flexible and can be easily extended.
