There were 6 deep salinity bottle samples from this cruise. The CTD salinity values were higher than the bottles by a median value of 0.002psu. However, incomplete flushing of Niskin bottles may lead to bottle values being lower than in situ values. Thus the CTD may look like it is reading higher than it really is. The CTD salinity data are considered +/- 0.003psu which is well within the expected accuracy for this equipment. 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 February 2018 cruise had a lot of scatter but suggested that dissolved oxygen was reading low 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.
