The recalibration of salinity is based on the results of other cruises using the same equipment; the calibration sampling for those cruises was limited and there is evidence of drift in the calibration. There was a lot of fine-scale noise in the salinity channel. Salinity should be considered +/- 0.005psu. Transmissivity - The data are nominal and unedited. Fluorescence - The data are nominal and unedited. -------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
