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 8.7381 28.6353 5 2.0 8.6554 29.1791 10 2.9 8.6688 29.2282 7 3.9 8.6884 29.2447 7 4.9 8.6959 29.2638 7 5.9 8.6676 29.3658 7 6.9 8.5868 29.5777 8 8.0 8.5128 29.7080 8 9.0 8.4823 29.7398 8 10.0 8.4341 29.7777 8 11.0 8.4732 29.8111 7 11.9 8.4142 29.8561 8 13.0 8.2867 30.0103 7 14.0 8.2099 30.2364 7 15.0 8.1946 30.3091 7 16.0 8.1819 30.3545 7 17.0 8.1469 30.4394 7 18.0 8.1330 30.4706 7 18.9 8.1176 30.4972 8 20.0 8.1027 30.5331 6 20.9 8.0932 30.5582 7 21.9 8.0896 30.5785 7 23.0 8.0554 30.6730 7 24.0 8.0239 30.7489 7 25.0 7.9884 30.8242 7 26.0 7.9591 30.8987 7 26.9 7.9098 31.0120 7 27.9 7.8926 31.0606 6 28.9 7.8492 31.1441 7 30.0 7.8399 31.1611 6 31.0 7.8474 31.1439 7 32.0 7.8449 31.1499 7 32.9 7.8305 31.1806 7 33.9 7.8022 31.2327 7 34.9 7.7917 31.2508 7 35.9 7.7801 31.2622 7 36.9 7.7691 31.2733 7 38.0 7.7669 31.2754 7 39.0 7.7659 31.2770 7 40.0 7.7737 31.2667 8 40.7 7.7724 31.2682 5
