It was hypothesized that Microcystis will overwinter in sediments and may be transported, along with phosphorus, to the water column when environmental conditions support algal bloom formation. Before, during, and after the Microcystis algal bloom, surface water and sediment samples were collected and analyzed from six fixed locations in the Western Lake Erie Basin. Detectable Microcystis concentrations were present in the sediment during and after the bloom at all six sites ranging from 5.5x104 to 2x105 cells per gram of dry sediment. This corresponded with the appearance of detectable Microcystis concentration in the lake during and after the bloom at five of the six sites ranging from 5x103 to 7x104 cells per milliliter across the entire water column. However, phosphorus concentrations in the sediment could not be correlated with any significance to the Microcystis cell density in the lake during or after the bloom. These findings suggest that Microcystis colonies do deposit into Lake Erie sediments and that these colonies may remain at some sediment sites until bloom formation the following summer. 2010-09-09 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1272581269 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1272581269 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
