Dissolved Oxygen and pH:SBE data are nominal and unedited, except that some records were removed in editing temperature and salinity and some bad near-surface dissolved oxygen data were removed. Channel Fluorescence:URU:Wetlabs was removed from casts #1001-1035 because the protective cap had not been removed. The data that remain are nominal. Some small negative values in fluorescence were set to 0 using program Calibrate. There was no calibration sampling available from this cruise. An inter-ship comparison of 2 casts from a June 2017 cruise using these sensors with a cast from a cruise that did include calibration sampling, suggested that the salinity values from this CTD were accurate but that dissolved oxygen values were likely low by up to 4%. WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data were available at the time of processing. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real.
