In July 2007, the Southeast Coast Network and the University of Georgia conducted anassessment of estuarine water and sediment quality in the waters surrounding CumberlandIsland National Seashore as a part of the National Park Service Vital Signs MonitoringProgram. Monitoring was conducted following methods developed by the U.S. EnvironmentalProtection Agency as a part of the National Coastal Assessment Program and includedlaboratory analysis for chlorophyll a, total dissolved nitrogen and phosphorous and fieldmeasurements of water temperature, pH, dissolved oxygen, and salinity. Estimates of waterclarity, adjusted for naturally occurring turbidly conditions, were made using secchi depthmeasurements.Overall water-quality conditions around Cumberland Island National Seashore with respectnutrients, chlorophyll a, dissolved oxygen, and water clarity were fair at all sites. Total dissolved phosphorus levels were rated as poor at 63% of sites and was the only water qualityparameter rated to be in poor condition during this assessment. Total dissolved nitrogen and chlorophyll a levels were rated as fair and good to fair, respectively. Overall sediment conditions in the estuarine waters surrounding Cumberland Island indicated generally good conditions.
