The regression lines and equations are based on data points shown as black-filled diamond; data points not included in the regression analysis are shown as white-filled diamonds. Graph A shows the regression of sediment THg versus sediment MeHg; Graph B shows the regression of sediment THg versus porewater THg, and Graph C shows porewater THg versus porewater MeHg. Data are shown for all seasonally inundated sediments measured during full-pool conditions in the spring and summer.
