CTD salinity values were higher than the 2 bottle samples below 300db by 0.006psu. That difference is likely due primarily to incomplete flushing of Niskin bottles so that samples represent conditions 10m higher in the water column where salinity is lower. No recalibration was applied to the CTD salinity. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. Surface saturation values varied greatly with low values in areas of active mixing, but were mostly between 80% and 100% in the central Strait of Georgia. Calibration errors for these sensors generally involve values being low by 2% to 4%.
