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 10.7913 22.2240 5 2.0 10.2563 24.3408 8 3.0 9.8637 26.0958 6 4.0 9.7034 26.9755 7 5.0 9.2142 28.4557 7 5.9 8.6339 29.8673 6 6.9 8.3773 30.4139 6 7.9 8.3028 30.5239 7 9.0 8.2087 30.6707 7 10.0 8.1496 30.8024 6 11.0 8.0864 30.9263 7 11.9 8.0574 30.9938 6 12.9 8.0406 31.0296 7 13.9 8.0273 31.0530 7 14.9 8.0102 31.0914 7 15.9 7.9853 31.1484 7 17.0 7.9362 31.2446 7 18.0 7.9246 31.2700 7 18.9 7.9156 31.2871 6 19.9 7.9062 31.3032 6 20.9 7.8930 31.3266 7 21.9 7.8865 31.3378 6 22.9 7.8789 31.3493 7 24.0 7.8795 31.3495 9 24.5 7.8838 31.3483 1
