The Effects Of Rainfall-Runoff On Particulate Organic Carbon Cycling In Salt Marshes, Si Chen

Theses and Dissertations

Low tide rainfall-runoff processes have been proposed as a kind of coastal ocean "hot moment" capable of transporting disproportionately large amounts of material from the salt marsh surface to the water column. However, the resulting organic matter cycling has not been well characterized and the cumulative effects of recurring short-term low tide rainfall events are not known, especially in the context of outwelling. The purpose of this Ph.D. research is to quantitatively evaluate the effects of low tide rainfall on particulate organic carbon (POC) cycling in a South Carolina salt marsh.
