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 11.7509 25.1985 5 2.0 11.6033 25.3948 8 2.9 11.4695 25.6749 7 3.9 11.3920 25.9707 6 4.9 10.3166 27.9113 7 6.0 9.3722 29.7108 7 6.9 9.1939 30.0725 6 7.9 9.0546 30.3215 7 9.0 9.0381 30.3566 6 9.9 9.0129 30.3916 6 10.9 8.9856 30.4327 6 12.0 8.9565 30.4785 7 13.0 8.9236 30.5273 6 14.0 8.9129 30.5456 6 14.9 8.8901 30.5796 5 15.9 8.8850 30.5888 6 16.9 8.8727 30.6100 6 18.0 8.8091 30.7042 7 18.9 8.7421 30.8021 5 19.9 8.7191 30.8368 6 20.9 8.7052 30.8573 7 22.0 8.6897 30.8807 6 23.0 8.6403 30.9477 5 24.0 8.6253 30.9739 6 25.0 8.5762 31.0447 5 26.0 8.5455 31.0977 6 27.0 8.5200 31.1414 6 28.0 8.5197 31.1465 5 28.9 8.5170 31.1605 6 29.9 8.4523 31.2396 6 30.9 8.3943 31.2883 6 31.9 8.3796 31.2973 6 32.9 8.3756 31.2973 6 33.9 8.3648 31.3065 6 35.0 8.3539 31.3205 7 36.0 8.3345 31.3430 6 36.9 8.3124 31.3683 7 38.0 8.2925 31.3890 6 38.9 8.2833 31.3979 6 40.0 8.2747 31.4065 8 40.8 8.2690 31.4126 6
