Objective:

Cyanobacterial algal blooms are common in many eutrophic lakes in Florida. Although cyanobacteria have had considerable impact on freshwater quality within the state since the mid 1900s, the timing and causes of their appearance have remained unknown because water-quality monitoring began in Florida only after 1980. This project’s researchers proposed to recover sediment cores from six eutrophic central Florida lakes and to analyze sedimented algal pigments to document the onset of cyanobacterial presence. Their goals were to track the appearance and persistence of cyanobacteria, and using existing paleolimnological data on historical water quality from these sites, to examine the relationship between cyanobacterial proliferation and eutrophication. Their objective also was to determine the water-quality conditions that promote cyanobacterial persistence and lead to a shift to cyanobacterial dominance.
