Data Processing Notes: ---------------------- The length of the surface soaks were shorter than recommended with many being less than 75 seconds. This does not allow enough time for equilibration of pumped channels. The soaks were generally at about 5-6m with no return to the surface before the full cast was run. Fluorescence, Dissolved Oxygen and pH:SBE data are nominal and unedited, except that some records were removed in editing temperature and salinity. Channel Fluorescence:URU:Wetlabs had some very small negative values in deep water which were set to 0 using program Calibrate. There was no deep salinity bottle 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 the salinity values from this CTD were reasonably accurate. There was near-surface salinity sampling during this cruise but the results of a comparison with the CTD data are considered unreliable. An initial examination of an early 2018 cruise with the same equipment and deep sampling suggests that the CTD salinity values are quite accurate. 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%. That error is likely to have increased with time. 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.
