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 11.9826 13.0735 5 1.9 11.9529 13.1260 8 2.9 11.8355 13.4024 7 3.9 11.5635 14.1642 7 5.0 11.1948 15.6632 7 6.0 10.6909 19.2111 8 7.0 9.8407 24.4839 8 7.9 9.3241 26.6683 8 8.9 8.9229 27.8719 8 9.9 8.4501 28.9997 7 11.0 8.1884 29.6767 7 12.0 7.9634 30.2048 7 12.9 7.9328 30.3122 6 13.9 7.9125 30.3612 7 14.9 7.8730 30.4522 6 15.9 7.8347 30.5425 7 17.0 7.8268 30.5659 7 18.0 7.8190 30.5901 6 18.9 7.8124 30.6312 6 20.0 7.8120 30.6560 7 21.0 7.8033 30.6843 6 22.0 7.7790 30.7395 8 23.0 7.7570 30.7702 7 24.0 7.7427 30.7973 7 25.0 7.7367 30.8139 6 26.0 7.7338 30.8218 7 26.9 7.7300 30.8306 6 27.9 7.7254 30.8447 6 28.9 7.7066 30.8969 7 30.0 7.6970 30.9305 7 31.0 7.6938 30.9425 7 32.0 7.6900 30.9568 7 33.0 7.6844 30.9781 6 33.9 7.6817 30.9919 7 34.9 7.6823 30.9913 8 35.9 7.6818 30.9947 7 36.9 7.6815 31.0016 6 37.9 7.6789 31.0165 7 39.0 7.6718 31.0362 7 39.7 7.6687 31.0468 4
