Salinity calibration sampling from this cruise was insufficient to determine how well the sensors were working. Previous cruises had limited sampling but suggest that salinity is within 0.005psu. There was no dissolved oxygen sampling during this cruise and most other cruises using this equipment since it was last serviced. There was an inter-ship comparison in June 2017 for 1 cast only that 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 was limited to the top 50m 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. It is recommended that extracted chlorophyll values be used where available. For details on the processing see document: 2018-093_Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
