Water quality in four regions of the Maryland Coastal Bays: assessing nitrogen source in relation to rainfall and brown tide
Monitoring water quality and determining nutrient inputs is essential to assess ecosystem health. Partnering with the Maryland Coastal Bays Program and the Department of Natural Resources, this study focused on four regions in Maryland's Coastal Bays. These regions, St Martins River, Public Landing, Johnson's Bay, and Chincoteague Island, were found to be nitrogen 'hotspots' by the 2004 water quality assessment study. This data report provides a spatially explicit Water Quality Index and extent of sewage / septic nitrogen incorporated by two biological indicators, the macroalgae Gracilaria, and the native oyster, Crassostrea virginica.
