Oxygen:Dissolved:SBE data were removed from the top 5db because of suspiciously low values. Data below that are nominal and unedited. There was no dissolved oxygen sampling. The calibration of the dissolved oxygen sensors tends to drift towards lower values, so Oxygen:Dissolved:SBE values are likely low by a few %. There was no calibration sampling during this multi-leg cruise, but a similar cruise that overlapped with this one, and used the same equipment, did have limited salinity and extracted chlorophyll sampling and offered some evidence that the CTD fluorescence, temperature and conductivity were well calibrated.
