Description: 
CTD salinity (PSS-78). CTDSAL is the calculated corrected value of salinity derived from the conductivity sensors on the CTD unit at the time of the bottle trip. CTDSAL is compared with SALNTY which is the PSS-78 value measured from the actual samples drawn from the niskin bottles themselves. Reporting both is meant, among other things, as a of show the goodness of fit, source of quality coding and offer alternative for measurements/calculations if one of those values is missing or lacking a good quality code.
