These errors are likely to be larger than the calibration errors. Salinity should be considered +/-0.05psu in areas of high gradients and +/-0.01psu elsewhere. The transmissivity data is unedited. ********************************************************************* Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8410 Portasal Salinometers which are standardized with IAPSO standard seawater. The bottle depths are approximate. Estimates were made for the depth of the bottles below 50m based on study of the CTD data. *CALIBRATION $TABLE: CALCULATED CHANNELS !
