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 10.5999 26.4488 5 1.9 10.5099 26.6214 7 2.9 10.2548 27.0923 7 4.0 9.9131 27.7532 6 5.0 9.5474 28.5461 5 5.9 8.6951 30.0796 5 6.9 8.5111 30.5421 6 8.0 8.4599 30.6511 6 9.0 8.4011 30.7519 5 10.0 8.3463 30.8365 6 10.9 8.3225 30.8683 5 11.9 8.3085 30.8915 6 12.9 8.3029 30.9015 6 13.9 8.2978 30.9097 7 15.0 8.2900 30.9213 5 15.9 8.2857 30.9286 6 16.9 8.2837 30.9341 5 17.9 8.2625 30.9664 6 18.9 8.2505 30.9867 5 19.9 8.2526 30.9877 6 21.0 8.2501 30.9917 6 22.0 8.2451 30.9998 5 22.9 8.2131 31.0469 5 23.9 8.1640 31.1234 6 25.0 8.1390 31.1624 6 25.9 8.1285 31.1797 5 27.0 8.1086 31.2087 7 28.0 8.0890 31.2342 6 29.0 8.0497 31.2828 9
