For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". There was no salinity calibration sampling, but evidence from previous cruises suggests errors are <0.002psu. There was no dissolved oxygen calibration sampling. Recalibration was based on an earlier cruise. No estimate can be made for the accuracy of the Oxygen:Dissolved:SBE channel. Channel Oxygen:Dissolved:SBE was removed from events #8, 10 and 12 due to sensor malfunction.
