Аннотация

The objective of the paper is to provide sufficient tool for the big data processing and forecasting the state of the Okhotsk Sea ecosystem including its biocomplexity and survivability. Idea of Geoecological Information-Modeling System (GIMS) developed earlier by the authors of this paper is used for the synthesis of the Okhotsk Sea Ecosystem Model (OSEM) that parameterizes energy exchanges between main trophic components of the Okhotsk Sea taking into account the impacts of the environment and anthropogenic factors. Spatial resolution is 1/61/6. Dependence of the energy exchange processes on the environmental factors is modeled using parametrical descriptions with minimal level of uncertainty. Biological components are modeled by traditional balance equations the coefficients of which are defined from observational data. Simulation results show an existence of the critical ecosystem states when the ecosystem biocomplexity and survivability can reach dangerous levels. The ecosystem state prognosis is realized until 2100. Precision of the modeling results is better 79.9%.
