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 8.9350 29.2696 5 2.0 8.8652 29.4263 7 3.0 8.7242 29.7593 6 4.0 8.6802 29.9018 7 4.9 8.5784 30.1384 6 5.9 8.5457 30.2253 7 7.0 8.4762 30.3729 7 8.0 8.4238 30.4882 7 9.0 8.3785 30.5883 7 10.0 8.3167 30.7090 7 10.9 8.2835 30.7773 6 11.9 8.1715 30.9625 6 12.9 8.1379 31.0308 6 13.9 8.1319 31.0422 7 15.0 8.1293 31.0468 6 15.9 8.1198 31.0613 6 16.9 8.1183 31.0647 7 17.9 8.1101 31.0838 7 19.0 8.0064 31.2400 7 20.0 7.9949 31.2656 6 20.9 7.9860 31.2780 6 22.0 7.9825 31.2850 7 23.0 7.9679 31.3062 6 24.0 7.9468 31.3348 6 25.0 7.9440 31.3403 6 26.0 7.9097 31.3817 7 27.0 7.9040 31.3897 6 28.0 7.9020 31.3924 7 29.0 7.8992 31.3959 6 30.0 7.8965 31.4003 7 31.0 7.8938 31.4046 6 31.9 7.8875 31.4120 7 33.0 7.8861 31.4129 6 33.9 7.8854 31.4140 7 34.9 7.8840 31.4153 7 36.0 7.8765 31.4223 9 36.7 7.8777 31.4228 5
