P. and S. Levitus, 1994). The precise meaning of these flags, as applied to only the very shallow parts of the profile used for COADS, is unknown. # Depth does not have a parameter code, but it is included as the first data in each depth level group. OCL Parameter Codes and Flags ---------------- Parameter #Code Temperature 1 Salinity 2 Oxygen 3 Phosphate 4 Silicate 6 Nitrate 8 Whole-profile flags (as a function of parameter) 0 - accepted profile 1 - failed annual standard deviation check 2 - two or more density inversions (Levitus 1982 criteria) 3 - flagged cruise 4 - failed seasonal standard deviation check 5 - failed monthly standard deviation check 6 - failed annual and seasonal standard deviation check 7 - failed annual and monthly standard deviation check 8 - failed seasonal and monthly standard deviation check 9 - failed annual, seasonal, and monthly standard deviation check Flags on individual depths and observations Depth Flags: 0 - accepted value 1 - error in recorded depth (same or less than previous depth) 2 - temperature inversion of magnitude > 0.3 degrees/meter 3 - temperature gradient of magnitude > 0.7 degrees/meter 4 - temperature gradient (of > 0.7 degrees/meter) followed closely by a temperature inversion (of > 0.3 degrees/meter) or vice versa Observed Level Parameter Flags: 0 - accepted value 1 - range outlier (outside of range check) 2 - density inversion 3 - failed range check and density inversion check For complete details see Boyer, T.P. and S.
