It is frequently difficult to tell good salinity from bad. CTDEDIT was used to remove records corrupted by shed wakes near the top and bottom of the cast; salinity was cleaned and some salinity points were removed that appeared to be bad. -------------------------------------------------------------------------------------- Data Processing Notes: ---------------------- Conductivity, Fluorescence:URU:Wetlabs and pH:SBE data are nominal and unedited except that some records were removed in editing temperature and salinity. The CTD was soaked at 10m and then returned to the surface before running the full cast. However, the total soak time was usually only about 1 minute rather than the the recommended 2 minutes. In some cases the DO signal turns on right at the end of the soak or even after the downcast began so there may not have been time for the sensor to equilibrate. For cast #97 no useful DO data were available from 0-10db. There was no salinity or dissolved oxygen calibration sampling from this cruise, or from the 2 other cruises that used these sensors since they were last serviced at the factory. 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 problems are most notable where vertical salinity gradients are high and/or where descent rates are highly variable. The temperature data and dissolved oxygen data mostly look reasonable during downcasts, but there were problems in both during upcasts. While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, especially far from shore. These casts were mostly near shore and the CTD fluorescence values compare quite well with near-surface 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.
