The salinity was recalibrated based on a comparison with samples analyzed at IOS on an Autosal. Other samples run at sea on a Portasal appear unreliable based on a study of duplictes run on the two salinometers. The dissolved oxygen data in the CTD files should be considered • ±0.5ml/l from 0 – 125db • ±0.2ml/l from 125 – 400db • ±0.1ml/l from 400 – 1200db • data below 1200db are considered unreliable by the manufacturer. *CALIBRATION $TABLE: CORRECTED CHANNELS !
