Abstract
The CE-Qual-ICM model computes phytoplankton biomass and production as a function of temperature, light, and nutrients. Biomass is computed as carbon while inorganic nitrogen, phosphorus, and silica are considered as nutrients. Model formulations for production, metabolism, predation, nutrient limitation, and light limitation are detailed. Methods of parameter determination and parameter values are presented. Results of model application to a ten-year period in Chesapeake Bay indicate the model provides reasonable representations of observed biomass, nutrient concentrations, and limiting factors. Computed primary production agrees with observed under light-limited conditions. Under strongly nutrient-limited conditions, computed product is less than observed. The production characteristics of the model are similar to behavior reported for several similar models. Process omitted from the model that may account for production shortfalls include variable algal stoichiometry, use of urea as nutrient, and vertical migration by phytoplankton.
