The CTD was soaked at the surface for between 0.6 minutes and 2.7 minutes. Some of the downcasts started before the dissolved oxygen sensor had turned on. There was no salinity or dissolved oxygen calibration sampling from this cruise. This was the first use of the sensors since they were last serviced at the factory so calibration drift is likely low. There are concerns about the reliability of the salinity data so they are only reported with 3 decimal places. The problems with salinity are somewhat random unstable excursions that derive from the conductivity channel and are likely due to variations in the alignment with temperature data. This may be due to variable flow rates possibly due to a pump/plumbing problem. The temperature data look fine. Near-surface salinity values are also questionable for some casts due to a very short surface soak. Dissolved oxygen values are likely to be high around 10 to 20m as bubbles are released as there was no initial 10m soak. For cases with very short soak periods the sensor had not turned on until the CTD was on its way down so near-surface data are missing. While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples. WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data were available at the time of processing. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real.
