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 11.5000 25.1562 5 1.9 11.4117 25.3686 9 3.0 11.3838 25.4864 7 4.0 11.1833 25.9748 6 5.0 10.2897 27.5693 7 6.0 9.7671 28.6273 6 6.9 9.2849 29.5082 6 7.9 9.0280 29.9970 6 8.9 8.8883 30.2605 7 10.0 8.7940 30.4255 6 10.9 8.6830 30.6050 6 11.9 8.6935 30.6001 6 12.9 8.6391 30.6851 7 13.9 8.6261 30.7105 6 14.9 8.6112 30.7376 6 15.9 8.6024 30.7570 6 17.0 8.5899 30.7803 6 18.0 8.5856 30.7903 6 18.9 8.5683 30.8225 5 19.9 8.5704 30.8218 6 20.9 8.5627 30.8381 6 22.0 8.5423 30.8842 7 23.0 8.5115 30.9515 6 23.9 8.4588 31.0456 5 24.9 8.4139 31.1247 6 25.9 8.3802 31.1910 6 27.0 8.3527 31.2439 6 28.0 8.3505 31.2492 5 28.9 8.3493 31.2507 6 30.0 8.3489 31.2505 6 31.0 8.3486 31.2549 6 32.0 8.3462 31.2561 6 33.0 8.3453 31.2559 6 34.0 8.3458 31.2549 6 35.0 8.3491 31.2632 6 36.0 8.3528 31.2648 6 37.0 8.3547 31.2639 6 38.0 8.3452 31.2754 6 39.0 8.3475 31.2739 5 40.0 8.3467 31.2735 7 40.7 8.3428 31.2765 4
