In motion the salinity is considered ±0.005psu. There were no salinity calibration samples and there is no history for these sensors since their most recent recalibration, so no comment can be made on the accuracy. Data from below 18.6db were not acquired due to instrumental problems. ---------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
