Data Processing Notes: ---------------------- The deployment method used was to lower the CTD to 10m, soak for 3 minutes and return to between 2.5db and 5db after which a full cast was run. Conductivity, Fluorescence:URU:Wetlabs, Oxygen:Dissolved:SBE and and Turbidity:Seapoint data are nominal and unedited, except that some records were removed in editing temperature and salinity. There were only 3 salinity calibration samples and there were a number of problems that made a comparison with CTD salinity unreliable. The temperature and conductivity sensors had been recalibrated recently, so CTD salinity is likely accurate. There was no extracted chlorophyll sampling. There was no dissolved oxygen calibration sampling. Near-surface saturation rates look reasonable and the sensor had been recalibrated shortly before the cruise, so values are likely reliable. Pressure was recalibrated based on analysis of near-surface data. For details on the processing see processing report: 2019-009-Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
