The Development and Calibration of a Spatially Simplified Multi-Class Phytoplankton Model for Saginaw Bay, Lake Huron

摘要

A multi-class, internal nutrient pool, phytoplankton simulation model was developed and applied to an extensive set of field data acquired in 1974 on Saginaw Bay, Lake Huron. Phytoplankton biomass was partitioned into five functional groups: diatoms, greens, heterocystous blue-greens, non-heterocystous blue-greens, and 'others'. The nutrients included in the model were phosphorus, nitrogen, and silicon. The model was applied to the inner portion of Saginaw Bay. Model results confirmed the soundness of pursuing a strategy of phosphorus control to reduce excessive phytoplankton growth in Saginaw Bay.
