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 10.1158 26.4387 5 2.0 9.8103 27.5748 7 3.0 9.6867 27.9848 6 4.0 9.2148 28.9314 6 4.9 8.8728 29.6296 6 6.0 8.6563 30.0115 6 7.0 8.5574 30.1915 6 8.0 8.4703 30.3230 6 8.9 8.4100 30.4258 6 9.9 8.3300 30.5455 6 10.9 8.2982 30.5903 6 11.9 8.2460 30.6630 6 12.9 8.2061 30.7242 6 14.0 8.1800 30.7610 7 14.9 8.1510 30.7965 6 15.9 8.1282 30.8227 7 17.0 8.1117 30.8414 6 17.9 8.0918 30.8662 7 19.0 8.0655 30.9002 7 20.0 8.0586 30.9095 6 21.0 8.0289 30.9482 7 22.0 7.9853 31.0043 6 22.9 7.9647 31.0251 7 23.9 7.9574 31.0363 7 24.9 7.9426 31.0667 7 26.0 7.9170 31.1079 6 27.0 7.8920 31.1452 6 28.0 7.8828 31.1606 6 29.0 7.8763 31.1722 6 30.0 7.8612 31.1976 6 31.0 7.8491 31.2166 5 31.9 7.8270 31.2330 6 33.0 7.8048 31.2653 7 34.0 7.7941 31.3043 6 35.0 7.7885 31.3226 6 36.0 7.7741 31.3479 7 37.0 7.7547 31.3720 6 37.9 7.7405 31.3838 7 39.0 7.7281 31.3968 8 39.7 7.7190 31.4080 4
