Biogeochemistry of Metals and Nutrients in Sediments

Research done by this project is expanding our understanding of the forms of nutrients (phosphorus) in lake and river sediments and providing data for models describing the movement of nutrients between water, sediment and biota. Studies focus on processes that lead to the release or retention of phosphorus (P) from sedimentary environments. Processes of interest to this project include, but are not limited to, P interactions with clays, organic matter, and poorly crystalline iron (Fe) oxides. This project examines the forms (species) of metals and nutrients in sedimentary environments.  Measurements include  oxidation-reduction conditions, the presence of complexing ligands, and mineral formation or dissolution. Our work with 31P Nuclear Magnetic Resonance (NMR) to determine the chemical forms of P in samples is done in collaboration with the Chemistry Department of James Madison University The forms of P in sediments determines  whether this nutrient is retained or released from sediments and also whether the P is bioavailable. Bioavailable nutrients in water bodies support biological growth including algal biomass.
