Abstract
The initial phases of the study involved mixing processes and tidal hydraulics; however, the study emphasis shifted to estuarine benthic systems as the importance of these systems became more apparent. A conceptual model of estuarine benthic systems was developed and a classification system of estuarine benthic deposits which is based on the availability of hydrogen acceptors and reactive iron was developed. Field studies demonstrated that estuarine sediments and overlying wastes could contain significant concentrations of free sulfides which are toxic to a variety of organisms. Field studies of benthic oxygen uptake and benthic sulfide release were conducted. Water quality profiles within the deposits also were determined. A number of laboratory studies were conducted to determine the rate of sulfate reduction. Results from experiments using extracts from benthic deposits and algal mats demonstrated a close relationship between the rate of sulfate reduction and the sulfate and soluble organic carbon concentrations. A general systems model of estuarine benthic systems was developed. A variety of activities which could contribute to significant environmental changes with estuarine benthic systems were identified.
