Added a new "Step 3" button to add Quality Codes to CTD.csv output (see CTD.csv data format web page) -

• PrQ = pressure quality code;
• T1Q & T2Q = primary & secondary temperature quality codes;
• S1Q & S2Q = primary & secondary salinity quality codes;
• Ox1Q & Ox2Q = primary & secondary oxygen sensor quality codes (these carry over to the umol/Kg oxygen values since they are derived from ml/L);
• FlQ = fluorometer quality code;
• ISUSQ = ISUS nitrate sensor quality code;
• SigTheta1Q & SigTheta2 = T1S1 & T2S2 calculated sigma-theta densities
• TransQ = Transmissometer quality code
• pHQ = pH sensor quality code
• SPARQ = Surface PAR quality code
• PARQ = Remote PAR quality code

Codes - the data quality codes will follow the CalCOFI legacy codes

• no code = good data
• 8 = questionable data; bad calibration or bio-fouling
• 9 = bad or no data; sensor or pump failure

These quality codes have been added to flag bad or questionable data collected by our Seabird 911+ CTD sensors. Sensor failure, bio-fouling, or bad calibrations can generate poor or bad data but may still be included in the data file.
