A submodel for internal nutrients, critical to prediction of phytoplankton growth dynamics, is described. Process equations were developed to represent storage of nutrients with separate mechanisms for nutrient uptake and assimilation, multiple—nutrient limitation by the threshold hypothesis, and light—dependent photorespiration. These have been incorporated into the ecosystem model MS.CLEANER and calibrated for @Avre Heimdalsvatn, Norway, an ultra—oligotrophic, subarctic lake. The model has been validated for Vorderer Finstertaler See, Austria.
