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 12.8764 23.8358 5 1.9 12.1644 24.7459 7 2.9 10.1770 27.3656 7 3.9 9.2736 28.8838 6 4.9 9.1756 29.1424 6 5.9 9.1519 29.2221 6 6.9 8.9585 29.6178 6 7.9 8.6942 30.1324 6 8.9 8.6364 30.2617 7 9.9 8.5986 30.3287 6 11.0 8.5461 30.4461 7 12.0 8.3949 30.7644 6 13.0 8.3626 30.8995 6 14.0 8.3395 31.0047 6 15.0 8.3283 31.0498 6 16.0 8.3243 31.0696 5 17.0 8.3212 31.0856 6 18.0 8.3167 31.1075 5 18.9 8.3146 31.1211 6 19.9 8.3114 31.1383 6 20.9 8.3058 31.1639 6 21.9 8.3006 31.1846 7 23.0 8.2968 31.1965 6 24.0 8.2927 31.2079 5 24.9 8.2873 31.2234 7 25.9 8.2850 31.2308 6 26.9 8.2821 31.2374 7 28.0 8.2784 31.2461 6 28.9 8.2663 31.2747 7 29.9 8.2650 31.2803 7 31.0 8.2612 31.2884 6 32.0 8.2555 31.2993 6 33.0 8.2522 31.3042 7 34.0 8.2503 31.3087 9 34.5 8.2539 31.3105 1
