Concept
Consumption rate of oxygen {O2 CAS 7782-44-7} {respiration} per day per unit volume of the water body by 18O-H2O-tracer addition, in-vitro incubation and membrane inlet mass spectrometry (MIMS) and differencing between 18O-derived gross oxygen production and net changes in dissolved oxygen concentration over a 24h incubation period.
