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 1.1 11.6243 23.9364 4 2.0 10.3250 26.7277 8 3.0 9.8149 27.7679 7 3.9 9.7369 27.9246 7 5.0 9.6060 28.1316 6 6.0 9.4952 28.3146 6 7.0 9.3459 28.6175 6 7.9 9.1518 29.0097 6 8.9 8.9737 29.3345 6 9.9 8.6518 29.8721 6 10.9 8.4987 30.1471 7 11.9 8.4855 30.1732 7 13.0 8.3997 30.2906 6 14.0 8.3543 30.3589 6 15.0 8.3379 30.3853 6 16.0 8.2612 30.4860 6 17.0 8.2099 30.5602 6 18.0 8.1756 30.6086 5 19.0 8.1579 30.6337 6 19.9 8.1469 30.6488 5 20.9 8.1360 30.6630 6 21.9 8.1292 30.6734 6 22.9 8.0751 30.7401 6 24.0 7.9477 30.8857 6 25.0 7.9098 30.9197 6 26.0 7.8761 30.9468 6 27.0 7.8623 30.9668 6 28.0 7.8380 31.0017 6 29.0 7.8226 31.0157 7 30.0 7.7933 31.0348 6 31.0 7.7795 31.0492 6 31.9 7.7729 31.0542 5 32.9 7.7691 31.0568 7 34.0 7.7585 31.0692 6 35.0 7.7443 31.0903 6 36.0 7.7429 31.0938 6 36.9 7.7422 31.0984 6 38.0 7.7389 31.1106 8 39.0 7.7348 31.1264 7 40.0 7.7275 31.1433 7 40.8 7.7237 31.1546 6
