Isotope effects of O2 consumption in a deep lake as means for understanding partitioning of O2 demand among microorganisms, particles, and sediment
The isotopic ratio 18O/16O of dissolved O2 in aquatic systems is affected by the preferential
biological uptake of 16O (ε). Studies over the past six decades reveal that during incubation …
