Data Processing Notes: ---------------------- THe comparison of SBE25 salinity with bottle samples suggests that the CTD was reading low. However, Salinity samples were stored for 4 months before they were analyzed. Based on recent cruises using the same types of bottle inserts, it appears that significant evaporation occurs after 2 months, and that by 4 months, bottle values are likely to read high by an average of >0.01. Furthermore, all samples came from about 8db where the salinity gradients were high, making the comparison even less suitable for recalibration of salinity. This was the first use of this CTD since the temeprature and conductivity sensors were last recalibrated, so it is expected that their calibrations would not have drifted significantly. No recalibration was applied to CTD salinity. The pressure sensor appeared to read high by 0.22db, which is within the accuracy quoted for the sensor. Pressure was recalibrated by adding 0.22db to avoid negative values. A pH sensor was attached to the CTD, but the data are not included in the files to be placed in the IOS Data Library because no field calibration information was available at the time of processing, and there are some concerns about how the sensors perform. For details on the processing see the report: 2012-50-proc.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
