Our work continues to focus on determining Microcystis growth and proliferation as well as microcystin concentrations. In Saginaw Bay, Lake Huron, 4 specific stations located above are monitored every other week to quantify Microcystis abundance and toxicity, nutrients, pigments, and other environmental parameters, as well as to further understand how Microcystis biomass correlates with toxicity. One of our future goals is to utilize our monitoring data and models to determine what quantities of SRP and dissolved phosphorus (DP) trigger harmful algal blooms, and how N contributes to toxin production.

We also have included data collected on Chlorophyll a concentrations, water temperature sampled from a CTD (conductivity, temperature, and depth) profiler, and secchi depth.
