Description :
The significance of organic carbon (C) burial in fluvial reservoirs on the global C cycle and atmosphere composition remains debatable. Over a 4-year period (2005–2008), dissolved concentrations and fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) were monitored at a Central Indiana fluvial reservoir (built in 1967) fed by streams draining a predominantly agricultural watershed. The results highlighted that the reservoir C budget was very sensitive to CH4 and N2O emission pulses following mixing and major discharge events.
