Nutrient Improvements in Chesapeake Bay: Direct Effect of Load Reductions and Implications for Coastal Management
This study used generalized additive models to link river flows and nutrient loads from the Chesapeake Bay watershed to nutrient trends in the estuary, allowing for the identification of exactly when and where responses to management efforts are occurring.
Description
In the Chesapeake Bay, decades of management efforts have resulted in modest reductions of nutrient loads from the watershed, but the corresponding improvements in estuarine water quality have not consistently followed. In this study, published in Environmental Science & Technology, generalized additive models were used to directly link river flows and nutrient loads from the watershed to nutrient trends in the estuary on a station-by-station basis, which allowed for identification of exactly when and where responses are happening.
