Abstract
The variability of denitrification potentials in estuarine sediments was measured during October 15-18, 1984 at ten stations in Chesapeake Bay. Selected chemical and physical characteristics of the sediments were also measured to investigate factors which may regulate denitrification in the estuarine ecosystem. Denitrification potentials increased at higher concentrations of nitrate except for two stations. Mainstem bay stations lacked any significant denitrification potentials increased at higher concentrations of nitrate except for two stations. Mainstem bay stations lacked any significant denitrification potential. Estimated ranges of ambient denitrification rates suggest that they may vary as much spatially due to the kinetic nature of denitrification as seasonally due to differences in nitrate concentration.
