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 12.2952 24.0799 5 1.9 10.7958 25.9104 7 2.9 9.8619 27.3976 8 4.0 9.2460 28.5816 6 4.9 8.8847 29.2822 6 6.0 8.6604 29.6894 7 7.0 8.5416 29.9128 6 7.9 8.5149 29.9825 6 9.0 8.4728 30.0697 6 10.0 8.4280 30.1649 5 10.9 8.4101 30.2117 6 12.0 8.4000 30.2411 6 12.9 8.3851 30.2852 5 14.0 8.3243 30.4493 7 15.0 8.2491 30.6433 6 16.0 8.2248 30.7098 5 16.9 8.2048 30.7655 6 18.0 8.1808 30.8367 7 19.0 8.1605 30.8948 6 19.9 8.1575 30.9048 6 21.0 8.1543 30.9177 6 22.0 8.1323 30.9872 5 23.0 8.1027 31.0919 6 24.0 8.0998 31.1133 5 25.0 8.1013 31.1164 5 25.9 8.0902 31.1724 5 27.0 8.0819 31.2232 6 28.0 8.0787 31.2376 5 29.0 8.0764 31.2476 6 30.0 8.0683 31.2792 5 31.0 8.0679 31.2880 6 32.0 8.0684 31.2893 5 32.9 8.0690 31.2925 6 34.0 8.0679 31.3088 6 35.0 8.0654 31.3184 6 36.0 8.0639 31.3195 6 37.0 8.0640 31.3191 6 38.0 8.0638 31.3197 6 39.0 8.0639 31.3188 6 40.0 8.0637 31.3185 7 40.8 8.0637 31.3184 8
