SeaCat salinity is prone to error due to mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. These errors are likely to be much larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05units in areas of high gradients. However, this cruise had large gradients only at the surface and the descent rate was generally very steady, so the errors should be much smaller than that. ---------------------------------------------------------------------- !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure :T0:C0 er_o ! ~bin ! _rec ! ords !------ -------- -------- ---- *END OF HEADER 1.2 9.9354 18.8595 5 1.9 9.9873 19.0609 9 3.0 11.0313 19.9217 8 4.0 11.0819 21.0380 7 4.9 10.0313 22.7462 7 5.9 8.9549 26.8141 8 7.0 8.5905 28.4030 7 8.0 8.4627 28.8468 7 8.9 8.3980 29.0532 8 9.9 8.2073 29.5043 8 11.0 8.0916 29.7912 7 11.9 8.0808 29.8316 7 13.0 8.0653 29.8709 8 14.0 8.0496 29.9080 7 14.9 8.0376 29.9351 8 15.9 8.0027 30.0079 8 17.0 7.9933 30.0328 8 17.9 7.9853 30.0554 7 18.9 7.9448 30.1513 8 20.0 7.9093 30.2291 8 21.0 7.8700 30.3030 8 22.0 7.7793 30.5021 8 23.0 7.7146 30.6565 8 24.0 7.6829 30.7286 9 25.0 7.6216 30.8518 8 26.0 7.6153 30.8658 8 26.9 7.6144 30.8675 9 28.0 7.6114 30.8730 8 29.0 7.6109 30.8739 8 30.0 7.6067 30.8805 7 31.0 7.6000 30.8912 6 32.0 7.5983 30.8947 7 33.0 7.5991 30.8963 7 34.0 7.6005 30.8966 7 35.0 7.6010 30.8987 7 36.0 7.6014 30.9000 7 37.0 7.5976 30.9102 7 38.0 7.5926 30.9222 8 39.0 7.5874 30.9342 8 40.0 7.5802 30.9505 8 40.9 7.5630 30.9857 9
