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 12.5100 17.2847 5 1.9 12.3197 18.2825 7 2.9 11.9800 19.4881 6 3.9 11.2561 21.8197 5 4.9 10.8130 23.1529 6 6.0 10.1105 24.8931 6 7.0 9.6639 26.2241 6 7.9 9.2778 27.1651 5 8.9 8.9005 28.1075 6 9.9 8.7423 28.5589 6 10.9 8.5886 28.9315 5 11.9 8.4186 29.3687 6 12.9 8.1938 29.8909 6 13.9 8.1007 30.1187 6 15.0 7.9549 30.3949 6 16.0 7.9031 30.5099 6 17.0 7.8818 30.5499 5 17.9 7.8736 30.5646 6 18.9 7.8688 30.5757 6 19.9 7.8556 30.6021 6 20.9 7.8606 30.6285 6 22.0 7.8053 30.7608 6 23.0 7.7720 30.8340 6 24.0 7.7542 30.8794 5 24.9 7.7485 30.9128 6 25.9 7.7674 30.9346 6 26.9 7.7962 30.9580 6 27.9 7.7808 31.0198 6 29.0 7.7804 31.0515 6 30.0 7.7892 31.0612 5 31.0 7.7928 31.0699 5 32.0 7.7972 31.0866 6 33.0 7.8037 31.1042 6 34.0 7.8132 31.1381 6 35.0 7.8135 31.1660 5 36.0 7.8127 31.1782 6 37.0 7.8125 31.1915 5 38.0 7.8133 31.2025 6 38.9 7.8069 31.2164 5 40.0 7.7999 31.2351 7 40.9 7.7957 31.2511 7
