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 10.0537 26.2962 4 1.9 9.8912 26.7502 7 3.0 9.6230 27.5341 7 4.0 9.3379 28.2975 6 5.0 9.0995 28.8237 7 5.9 8.7387 29.6208 6 6.9 8.0918 30.8184 6 7.9 7.9808 31.1174 7 8.9 7.9665 31.1535 6 10.0 7.9536 31.1770 7 11.0 7.9418 31.1820 7 11.9 7.9360 31.1813 6 13.0 7.9371 31.1791 7 14.0 7.9212 31.1843 6 15.0 7.9091 31.1941 6 16.0 7.9039 31.1958 7 17.0 7.8963 31.2045 6 17.9 7.8937 31.2136 6 19.0 7.8928 31.2192 7 20.0 7.8943 31.2230 6 21.0 7.8948 31.2254 7 22.0 7.8951 31.2266 6 23.0 7.8957 31.2272 7 24.0 7.8970 31.2292 6 24.9 7.8995 31.2319 7 26.0 7.9022 31.2373 7 27.0 7.9101 31.2541 6 27.9 7.9048 31.2872 7 28.9 7.8968 31.3041 7 30.0 7.8898 31.3181 7 31.0 7.8843 31.3296 6 32.0 7.8840 31.3304 7 33.0 7.8835 31.3315 7 34.0 7.8798 31.3384 7 35.0 7.8695 31.3546 7 35.9 7.8513 31.3851 6 37.0 7.8423 31.4002 7 38.0 7.8355 31.4116 7 39.0 7.8322 31.4189 6 40.0 7.8305 31.4222 7 40.8 7.8283 31.4256 6
