Such errors are likely to be larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05 units in areas of high gradients, but on the order of 0.005 where gradients are low and descent rate steady. There were no salinity calibration data available for this cruise and no recent factory calibrations, so significant drift in calibration is likely. CTD sensors #1449 and #1511 had not been calibrated since 2014.
