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 11.4754 25.4300 5 1.9 11.4126 25.5766 8 3.0 10.3236 27.3577 6 4.0 8.7994 29.8515 6 5.0 8.5738 30.3026 6 6.0 8.4868 30.4309 5 6.9 8.4825 30.4838 6 8.0 8.4676 30.5508 5 8.9 8.4293 30.6371 6 9.9 8.3997 30.7101 6 10.9 8.3953 30.7357 6 11.9 8.3961 30.7525 6 12.9 8.3834 30.7924 5 13.9 8.3695 30.8369 6 15.0 8.3602 30.8758 6 16.0 8.3523 30.8968 5 16.9 8.3451 30.9240 5 17.9 8.3440 30.9355 5 18.9 8.3439 30.9384 6 20.0 8.3435 30.9440 5 21.0 8.3425 30.9501 6 22.0 8.3413 30.9569 5 23.0 8.3406 30.9649 4 23.9 8.3392 30.9760 5 25.0 8.3358 30.9951 6 26.0 8.3354 31.0048 5 27.0 8.3358 31.0104 5 28.0 8.3366 31.0211 5 29.0 8.3440 31.0507 5 30.0 8.3467 31.0727 5 30.9 8.3460 31.0828 5 32.0 8.3420 31.1105 6 33.0 8.3307 31.1374 5 33.9 8.3297 31.1409 5 34.9 8.3189 31.1522 6 36.0 8.2990 31.1763 5 37.0 8.2967 31.2107 6 37.9 8.2959 31.2260 5 39.0 8.2931 31.2300 6 40.0 8.2741 31.2399 7 40.8 8.2665 31.2464 8
