Abstract:Using ^13C/^12C ratios in particulate organic carbon (POC), this study evaluated the fraction of terrestrially derived POC in Winyah Bay, South Carolina, an anthropogenically impacted estuary in the southeastern United States. Results from the mixing model, which should be viewed as an upper limit because of possible dilution from additional potential end-members, showed that between 50 and 90% of POC in the Winyah Bay estuary is of terrestrial origin. As this POC may be associated with river-transported pollutants, the potential for accumulation of pollutants in Winyah Bay is high because POC may become trapped in the estuary as part of either estuarine bottom sediments, circulation or food webs. Thus strategies for pollution monitoring and control in the estuary and its watershed are necessary for the future management of Winyah Bay natural resources.
