Oxygen:Dissolved:SBE values could not be confirmed as there was no calibration sampling for dissolved oxygen. However, a post-cruise factory calibration shows values to be consistently low by about 3.6%, so that value was used to recalibrate the sensor data. A post-cruise factory calibration confirmed that salinity values were low by at least 0.011psu. A correction of +0.011psu was applied.
