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 10.1295 8.6873 5 2.0 10.4802 17.3911 8 2.9 9.9698 23.0033 7 3.9 8.9866 27.2933 7 5.0 8.7442 28.1793 6 5.9 8.5449 28.7092 6 6.9 8.3828 29.1528 7 8.0 8.2938 29.3876 6 9.0 8.2465 29.5351 7 9.9 8.1540 29.7712 6 10.9 8.0199 30.0961 6 11.9 7.9913 30.1818 6 12.9 7.9450 30.2883 7 13.9 7.8870 30.4234 6 14.9 7.8455 30.5260 7 16.0 7.8078 30.5966 6 16.9 7.7681 30.6592 6 17.9 7.7580 30.7052 6 18.9 7.7547 30.7631 6 19.9 7.7303 30.8312 6 21.0 7.7173 30.8538 7 22.0 7.7108 30.8665 6 23.0 7.7029 30.8829 6 24.0 7.6909 30.9077 6 24.9 7.6610 30.9472 6 25.9 7.6297 30.9649 6 26.9 7.6142 30.9779 7 28.0 7.6324 30.9995 7 29.0 7.6423 31.0173 6 30.0 7.6437 31.0233 6 31.0 7.6446 31.0291 6 31.9 7.6433 31.0395 6 32.9 7.6394 31.0505 6 33.9 7.6333 31.0610 6 34.9 7.6282 31.0691 7 36.0 7.6228 31.0720 6 37.0 7.6213 31.0733 7 38.0 7.6203 31.0819 6 38.9 7.6191 31.0910 7 39.9 7.6191 31.0921 6 40.9 7.6181 31.0929 7 42.0 7.6163 31.0942 7 43.0 7.6154 31.0959 6 44.0 7.6139 31.0973 6 44.9 7.6051 31.1050 6 45.9 7.5810 31.1404 6 46.9 7.5693 31.1602 6 47.9 7.5664 31.1660 7 49.0 7.5502 31.1847 6 49.9 7.5437 31.1903 6 51.0 7.5393 31.1950 7 52.0 7.5347 31.2020 7 53.0 7.5305 31.2099 7 54.0 7.5285 31.2200 7 55.0 7.5238 31.2313 8 56.0 7.5084 31.2535 7 56.9 7.4977 31.2684 8 57.9 7.4958 31.2722 7 58.9 7.4886 31.2822 9
