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 11.3744 16.7098 5 2.0 11.2811 17.2921 10 2.9 10.3851 20.8361 8 3.9 9.2604 25.4095 8 4.9 8.7435 27.3966 6 5.9 8.3404 28.8173 7 6.9 8.2375 29.2147 7 7.9 8.2238 29.2669 8 8.9 8.1902 29.3812 8 9.9 8.0724 29.7590 7 10.9 7.9843 30.0870 8 12.0 7.8928 30.3761 7 12.9 7.8631 30.4646 7 13.9 7.8389 30.5215 7 14.9 7.8216 30.5619 8 16.0 7.8040 30.6028 7 17.0 7.7762 30.6606 6 17.9 7.7672 30.6813 7 18.9 7.7567 30.7016 7 19.9 7.7555 30.7046 7 21.0 7.7563 30.7035 7 22.0 7.7388 30.7385 7 23.0 7.7224 30.7755 7 24.0 7.7121 30.7991 7 24.9 7.7045 30.8213 8 26.0 7.7012 30.8325 7 27.0 7.6981 30.8409 7 28.0 7.6962 30.8443 7 28.9 7.6939 30.8470 7 30.0 7.6869 30.8605 7 31.0 7.6860 30.8669 6 32.0 7.6867 30.8693 7 33.0 7.6839 30.8830 7 34.0 7.6732 30.9096 6 34.9 7.6679 30.9203 6 35.9 7.6610 30.9293 7 37.0 7.6590 30.9357 6 37.9 7.6483 30.9684 6 39.0 7.6439 31.0033 7 39.8 7.6431 31.0134 6
