Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. However, a post-cruise factory calibration suggests values were low by about 3.5% so that value was used to recalibrate the sensor data. CTD salinity was found to be low by about 0.01psu in comparison to near-bottom bottles. A post-cruise factory calibration confirmed that values were low by at least that much. A correction of +0.01psu was applied. CTD fluorescence compared with surface extracted chlorophyll samples in the usual way, with fluorescence higher at low CHL and dropping to about 60% of CHL when CHL>5ug/L. Fluorescence was not recalibrated. For details on the processing see document: 2024-005_Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
