The main direction of research

Modeling of biogeochemical cycles and marine ecosystems under different climatic conditions in high-latitude regions of the World Ocean.

New directions of research.

Within the framework of the main theme, it is planned to analyze the variability of the current state of the northern high-latitude seas with the aim of isolating the "weather" component and extreme situations (floods, storms, blooms of harmful algae, etc.) according to modeling results and available observational data.
