Abstract: The report describes sediment-water flux measurements and associated observations in the water column and benthic sediments. Observations were conducted at four stations in the tidal Potomac River and adjoining Chesapeake Bay from May through October 1994. Measures were collected to provide data for development and improvement of a diagenetic model of sediment processes in freshwater and salt-freshwater transition regions. Sediment-water flux measurements included ammonium, nitrate + nitrite, phosphate, silicate, dissolved organic nitrogen, dissolved organic phosphorus, dissolved organic carbon, dissolved oxygen, total C02, total iron, total manganese, and methane. Constituents measured in the water column included ammonium, nitrate + nitrite, phosphate, silicate, dissolved organic nitrogen, dissolved organic phosphorus, dissolved organic carbon, dissolved oxygen, total C02, total iron, total manganese, sulfate, pH, and temperature. Constituents measured in the sediments included ammonium, nitrate + nitrite, phosphate, silicate, dissolved organic nitrogen, dissolved organic phosphorus, dissolved organic carbon, alkalinity, total CO₂, iron, manganese, chloride, sulfate, sulfide, and pH.
