Data Processing Notes: ---------------------- Recalibration of SBE25 salinity and temperature was based on a post-cruise factory report. It was assumed that all the drift in calibration occurred before this cruise, which may be wrong. Recalibration could not be based on the comparison with bottle samples because bottles were fired on the fly during upcasts, so studies to determine the depth from which the samples came provide only a very rough estimate. Storage of samples for 6 months before analysis might also lead to some error in the comparisons, though there is no evidence of that. The membrane for the dissolved oxygen sensor was found to have been torn or punctured when the sensor was sent to the factory for a post-cruise calibration. There was no calibration sampling for dissolved oxygen. The data are provided with fewer significant digits than usual to remind users that the values are uncalibrated and not trusted. Turbidity data were removed because the sensors malfunctioned and PAR:Reference data were removed from most casts due to malfunction. PAR, PAR:Reference, Dissolved Oxygen and Transmissivity data are nominal and have not been edited, except that some records were removed in the course of editing temperature and salinity. CTD Fluorescence data are nominal. These data were recalibrated, but only to correct an error. Comparison with extracted chlorophyll data and a study of typical values of chlorophyll for this region, indicated that the wrong gain had been entered in the configuration file.
