CTD salinity values were within +/-0.005 for 3 of the 4 bottle samples available from near the bottom of casts. No recalibration was applied. Extracted chlorophylls samples were available from the surface. The comparison of fluorescence values with chlorophyll followed the usual pattern of fairly close agreement for 7 cases with CHL ~1ug/L and ~50% of CHL for 1 sample with CHL ~5ug/L. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. Surface saturation values were low, between 74% and 90%. Most of the casts were very well-mixed in the top 5 to 20m which likely explains the low values. Calibration errors for this type of sensor generally involve values being low by a few % only.
