Agriculture activities in coastal catchments often contribute pollutant runoff such as nitrogen (N), phosphorus (P), and trace metals to estuarine environments. Here, we determine the historical impacts from agricultural expansion using sediment samples from an estuary and a coastal wetland downstre...
