Nutrient discharges to Biscayne Bay, Florida: Trends, loads, and a pollutant index

Science of The Total Environment, 2011
Changes in land use, management practices, and environmental conditions may all lead to detectable differences in nutrients transported to aquatic systems. Biscayne Bay, an oligotrophic estuary in southeastern Florida, requires minimal phosphorus and nitrogen inputs and here we quantified the effects of continued watershed development.
