There were 6 deep salinity bottle samples from this cruise. The CTD salinity values were lower than the bottles by a median value of 0.001psu which is well within the expected accuracy. However, delay in analysis may have led to increased bottle salinity values that would make the CTD appear to read lower than it really is. As well, incomplete flushing of Niskin bottles may lead to bottle salinity differing from in situ waters in an unpredictable way; local vertical salinity gradients were complex with some large reversals so the errors may be of variable sign. Some of these errors would be compensating. So the CTD salinity may be a little less accurate than it appears in the comparison, but is likely within +/- 0.003psu. 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 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.
