While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. There was no pH or dissolved oxygen calibration sampling. Salinity sampling was too limited to justify recalibration as samples all came from near the surface and at somewhat variable depth. However, the comparison of CTD salinity with bottle salinity suggests that the CTD is reading within 0.005psu. Comparison of fluorescence with extracted chlorophyll samples was used to help determine a suitable correction to the offset for the fluorometer as there were many negative fluorescence; that correction removed the many negative values found using the offset from the configuration file. WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data are available. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real.
