I am DO levels in stagnant waters from a stream mesocosm experiment. During the non-flow periods, DO saturation measurements are reaching maximums of 300% (26 mg/L, 21 degrees C). The flumes contained high amounts of filamentous algae and high light inputs, which might partially explain these values. Nevertheless, we are afraid that oxygen bubbles might be generating an artefact.
We are wondering which are the maximums levels recorded by other researchers in similar conditions?
Thanks all for your help and time,
Hi,

Hi Gregoire,
Thanks a lot for the information and the links! Really helpful!
Cheers,

The dissolved oxygen concentration (DO) is often measured with a Clark polarographic oxygen electrode, which calibration and conversion from percent saturation to molarity is addressed at § 2.2.1 (pp. 11-12) at the signalled reference:
