CTDEDIT was used to remove some records corrupted by shed wakes; salinity was cleaned. -------------------------------------------------------------------------------------- Data Processing Notes: ---------------------- Conductivity, Fluorescence:URU:Wetlabs and pH:SBE data are nominal and unedited except that some records were removed in editing temperature and salinity. All salinity sampling from this cruise came from near the surface, where vertical salinity gradients and local variability are expected to be high. As a result there is a high standard deviation in the differences between CTD and bottle salinity. When a few outliers are removed, the comparison with the downcast CTD salinity suggests that the CTD is within 0.005psu of bottles. Previous cruises had limited sampling but also suggested that CTD salinity was within 0.005psu. For more details see document "2018-073-bottle-CTD-comp.xls". There was no dissolved oxygen sampling during this cruise and all 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: 2018-073_Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
