Sediment Oxygen Demand and Its Effects on Dissolved Oxygen Concentrations and Nutrient Release; Initial Laboratory Studies

Abstract

Three different approaches for examining sediment oxygen demand (SOD) are discussed. These include the use of freshwater sediment amended with organic matter as a source of energy to drive SOD processes, the use of successive aerobic/anaerobic cycles to determine the flux of organic and reduced inorganic chemical species released from the sediment to the water column as a result of SOD, and the evaluation of interactions occurring between the sediment and water column in relation to SOD-driven processes occurring within the sediment. Results are summarized and discussed in terms of measurement and analytical techniques used to describe SOD interaction in fresh and saltwater sediments.
