Description:
Sampling level identifier denoting outliers. 1=Oxic ---> 5=Deep. 0 = Outlier. Abrupt vertical oxygen gradients and the lagged depth control of the MOCNESS tow caused DO values to be less than half or more than double the desired DO values in seven out of 40 nets (M1-Oxic, M1-Hypoxic, M6-Hypoxic, M3-Suboxic, M6-Suboxic, M7-Suboxic and M8-Anoxic). These are the outliers, marked as 0.
