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 10.0485 23.3826 5 1.9 9.9066 24.0124 8 2.9 9.5639 25.4818 7 4.0 8.8921 27.8259 7 4.9 8.6043 28.7998 6 5.9 8.4392 29.3373 7 6.9 8.3769 29.5382 7 7.9 8.2531 29.8504 7 8.9 8.2065 29.9593 8 9.9 8.1915 29.9808 7 11.0 8.1750 30.0114 7 12.0 8.1374 30.0941 7 13.0 8.0943 30.2068 6 14.0 8.0766 30.2721 7 14.9 8.0211 30.4110 7 15.9 7.9067 30.6622 7 16.9 7.9016 30.6812 8 17.9 7.8956 30.6913 7 19.0 7.8889 30.7035 8 20.0 7.8817 30.7199 7 20.9 7.8564 30.7798 8 22.0 7.8288 30.8493 8 23.0 7.8252 30.8613 7 23.9 7.8216 30.8708 8 25.0 7.8134 30.8882 7 26.0 7.8099 30.8976 7 27.0 7.8056 30.9065 8 28.0 7.7976 30.9214 8 29.0 7.8001 30.9193 10 30.0 7.7689 30.9846 8 31.0 7.7025 31.1234 7 31.9 7.6809 31.1789 7 33.0 7.6805 31.1821 8 33.9 7.6822 31.1749 7 34.9 7.6873 31.1529 8 36.0 7.6884 31.1497 7 36.9 7.6896 31.1489 9 37.9 7.6853 31.1705 8 39.0 7.6758 31.2121 9 40.0 7.6710 31.2345 8 41.0 7.6681 31.2485 9 41.6 7.6679 31.2526 3
