Calibration sampling for salinity and dissolved oxygen was limited to 2 casts. The salinity comparison was consistent with small drift which was also found during a post-cruise factory calibration. The comparison of SBE dissolved oxygen with calibration samples was consistent with previous uses. That channel was recalibrated. No estimate is made of accuracy for Oxygen:Dissolved:SBE as there was insufficient sampling but no particular problems were noted.
