Harmful algal blooms; Ohio river
The frequency of harmful algal blooms (HABs) has been increasing across the globe, especially in river ecosystems. Although more common in lakes, more HABs have been reported in rivers in the past decade, particularly in the Ohio River. In 2019, a HAB stretched 200 to 300 miles throughout the Ohio River from September to October. Samples were collected for the duration of the 2019 bloom (August-October) in the McAlpine Pool in Louisville, KY to compare microcystis toxin (microcystin) concentrations on a temporal and spatial scale. Different habitats (bay, creek, river) were sampled throughout the bloom, and two additional sampling days, one in September and one in October, were taken from a boat in various habitats throughout the channel of the river. Wind and temperature were also documented for each sample. ELISA kits were utilized to determine the presence and concentration of microcystin. There was some significance spatially and temporally, however, more samples are needed to draw these conclusions.
