Comment:
Sound speed and pinger depth correction unkown. Use with care.
CTD data from stations 1 and 2 were measured with a different CTD system. This data has a significantly higher uncertainty because the limited calibration. >0.01 PSU and >5 µmol/kg, respectively. Please use this data with caution. Please also note that the calibration with Winkler titration might have problems with low oxygen values. Reported CTD oxygen values lower than 3 mumol/kg might actually be lower. Possibly even near 0 mumol/kg. Please use this data with caution.
Wetlabs Fluorescence offset is 0.007 (subtract this from the values to remove deck offset)
