Comment:
Low Oxygen values are likely too high by 1 to 2 µmol/kg, higher values are ok. Near surface S values are problematic because of biology. A few negative oxygen values appear to be caused by an overshoot of Seabirds oxygen hysteresis correction in extremely strong vertical oxygen gradients.
PAR with BadValue or NaN might need replacement by 0
Fluorescence and Turbidity data still contain deck offsets. Use with caution.
