A multidisciplinary complex of numerical models FRESCO (Finish–Russian–EStonian COoperation) simulating atmosphere–hydro-ecosystem dynamics is presented. The methodology of numerical treatment based on splitting with respect to physical and biochemical processes is used and offline calculation of ecosystem components is implemented. The hydroecological modelling complex is applied to study the plankton spatial development during its growth period in the Muuga Bay of the Baltic Sea and the Lake Peipsi. The experiments demonstrate the efficiency of the implemented numerical technique. The calculation results suggest that the ecosystem component behavior peculiarities are caused by the combined effect of upwelling and turbulent mixing. For example, this coupled phenomenon forms stretched plankton clouds in the western part of the Lake Peipsi.
