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 11.9972 13.4630 5 1.9 11.9579 13.5481 9 3.0 11.9770 13.5163 6 3.9 11.9372 13.6359 7 4.9 11.9563 13.9750 7 6.0 11.8481 15.7858 6 7.0 10.3055 24.0381 7 8.0 9.1818 28.0136 6 8.9 9.0215 28.5116 7 9.9 8.8715 28.8245 7 11.0 8.7262 29.0884 7 12.0 8.6092 29.3141 6 12.9 8.3262 29.8530 6 14.0 8.1583 30.2459 7 14.9 8.1451 30.2904 6 16.0 8.0924 30.3889 7 17.0 8.0685 30.4743 6 18.0 8.0690 30.4836 6 19.0 8.0635 30.4854 7 20.0 8.0458 30.5065 6 21.0 8.0319 30.5352 6 22.0 8.0410 30.5488 7 23.0 8.0442 30.5688 6 23.9 8.0320 30.5747 7 25.0 8.0263 30.5762 7 26.0 8.0040 30.6312 7 27.0 7.8772 30.8792 6 28.0 7.8641 30.9430 7 29.0 7.8623 30.9616 7 29.9 7.8592 30.9799 8
