JACOBS, S., R. F. HERRMANN, AND R. Wilson. Pilot Phase To Evaluate Efficacy Of Silica Dosing To Stimulate Diatom Growth In a Hypereutrophic Lake Impacted By Cyanobacterial Blooms. Presented at AlgaeVenture Systems Inc. Meeting, Marysville, OH, February 09, 2011.
Impact/Purpose:
To determine the relative abundance of phytoplankton species using FAME analysis. To determine if FAME analysis can be used to track phytoplankton community profiles.
Description:
This presentation describes measurements made and data collected during an experiment intended to increase silica concentration in a hyper-eutrophic lake impacted by cyanobacteria blooms. Silica was added to the water column in the hopes of encouraging diatom phytoplankton species to proliferate and out-compete cyanobacteria. The treatment and experiment were conducted by Algaeventure Inc. under contract to the Ohio Department of Agriculture and was monitored by the Ohio EPA. NRMRL provided assistance and water quality data during the trial, and attempted to determine the relative abundance of phytoplankton species using FAME analysis, a novel application of this procedure. FAME data was compared to cell count data collected by the Ohio EPA to determine if FAME can be used to track phytoplankton community profiles.
