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 9.0703 27.4706 5 1.9 8.8112 28.2793 9 2.9 8.6851 28.6767 9 3.9 8.6267 28.8722 7 4.9 8.4170 29.5661 8 5.9 8.2895 30.0563 8 6.9 8.2773 30.1319 8 8.0 8.2435 30.2243 8 9.0 8.2161 30.2973 7 9.9 8.2106 30.3113 8 10.9 8.2059 30.3222 9 11.9 8.1972 30.3436 7 12.9 8.1880 30.3664 8 13.9 8.1697 30.4043 8 15.0 8.1509 30.4485 8 16.0 8.1407 30.4730 7 17.0 8.1430 30.4702 8 17.9 8.1426 30.4728 8 18.9 8.1403 30.4793 9 20.0 8.1438 30.4812 9 21.0 8.1411 30.4871 8 21.9 8.1396 30.4942 8 22.9 8.1245 30.5298 9 23.9 8.1016 30.5767 9 25.0 8.0809 30.6152 9 26.0 8.0862 30.6064 9 27.0 8.1179 30.5545 9 28.0 8.1325 30.5278 10 29.0 8.1263 30.5390 10 30.0 8.1082 30.5727 8 31.0 8.0977 30.5976 10 31.9 8.0975 30.5963 8 33.0 8.0962 30.5954 10 33.9 8.0802 30.6245 9 35.0 8.0633 30.6558 10 35.9 8.0515 30.6780 9 37.0 8.0514 30.6797 10 37.9 8.0469 30.6948 9 39.0 8.0442 30.7063 10 39.8 8.0441 30.7101 6
