Water Quality Monitoring and Lake Ecosystem Modelling: an Integrated Approach to Assess Cyanobacterial Blooms

Abstract : In the last decades, the incidence of harmful algal blooms in surface waters has increased in frequency, severity and duration. Short and long term management approaches can address the problem of cyanobacteria blooms. A real-time, autonomous, monitoring program, coupled with a one dimensional deterministic model, was initiated for Missisquoi Bay, Canada in the summer of 2007. Preliminary results from vertical profiles in a pelagic zone show a homogenous distribution of temperature, pH, chorophylle a concentration and cyanobacteria density. Phycocyanin measurements by an in vivo fluorescence probe show high cyanobacteria concentration varying between 1X104 to 1X105 cell/mL.
