There were 8 deep salinity bottle samples during this cruise. The CTD salinity values were higher than the bottles by a median value of 0.0031psu which is within the expected accuracy. Some of this difference may be due to that fact that flushing of Niskin bottles is somewhat inefficient so that the water in the bottles may have come from slightly higher in the water column. A comparison with an SBE911+ cast during a previous cruise also showed that the salinity was likely within expected accuracy. No recalibration was applied to the CTD salinity. There was no dissolved oxygen sampling during this cruise or previous cruises using this equipment in 2017. 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 dissolved oxygen values were likely low by up to 4%. A comparison with an SBE911+ cast at the same site during a recent cruise had a lot of scatter but suggested that dissolved oxygen was reading low by at least 5%. Channel Oxygen:Dissolved:SBE was recalibrated by adding 5% to all values. 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. Warning: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples.
