These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding...
Hourly and daily variation of sediment redox potential in tidal wetland sediments
W. James Catallo, editor(s)
1999, Biological Science Report 1999-0001
Variation of electrochemical oxidation-reduction (redox) potential was examined in surface salt march sediments under conditions of flooding and tidal simulation in mesocosms and field sites. Time series were generated of redox potential measured in sediment profiles at 2-10 cm depth using combination Pt-Ag/AgCl (ORP) electrodes. Redox potential data were...
