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 9.1494 3.9963 5 1.9 12.0885 10.3467 8 2.9 11.7756 13.8485 8 3.9 11.1321 18.2072 7 4.9 10.0413 24.0807 7 5.9 9.5996 26.1081 7 6.9 8.8415 28.2115 6 8.0 8.6317 28.8340 8 9.0 8.5436 29.0554 7 9.9 8.4096 29.2958 7 11.0 8.2563 29.5819 7 11.9 8.2116 29.6684 6 12.9 8.1638 29.7488 7 14.0 8.1295 29.8124 7 15.0 8.0136 29.9997 7 16.0 7.9593 30.0924 7 16.9 7.9286 30.1423 7 17.9 7.8519 30.2693 8 19.0 7.7348 30.4702 7 19.9 7.7271 30.4909 7 20.9 7.7237 30.4991 8 21.9 7.7217 30.5063 8 22.9 7.7171 30.5248 7 24.0 7.7149 30.5400 8 25.0 7.7095 30.5680 8 26.0 7.7038 30.5874 8 27.0 7.7011 30.6020 6 28.0 7.6969 30.6197 8 29.0 7.6945 30.6522 7 30.0 7.6914 30.6920 8 31.0 7.6908 30.7142 7 31.9 7.6940 30.7338 7 33.0 7.6921 30.7502 7 34.0 7.6850 30.7676 6 34.9 7.6834 30.7763 7 35.9 7.6829 30.7802 7 36.9 7.6784 30.7894 8 38.0 7.6742 30.7967 7 38.9 7.6725 30.7997 9 40.0 7.6691 30.8039 8 40.7 7.6710 30.8048 4
