Working towards a forecast of Lake Erie cyanobacterial bloom toxicity
Toxic cyanobacterial blooms have become a familiar summer occurrence in Lake Erie since the late 1990s. It is well known that the primary driver of bloom biomass is the spring phosphorus load from the Maumee River; however, fundamental questions remain about the controls and predictability of toxin production. The factors influencing the dynamics of toxic and non-toxic strains within blooms are only beginning to be understood, but they may be at the point where reasonable predictions of changes in toxicity could be possible. While phosphorus has a definite role in HAB dynamics, nitrogen may also be necessary for the occurrence and biomass of cyanobacteria and the toxicity of the blooms. By linking process models and field experiments, we are developing a forecast for cyanobacterial bloom toxicity in Lake Erie.
