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 13.0849 7.8683 5 1.9 12.9385 8.9513 7 2.9 11.7497 15.1435 6 3.9 10.7143 20.8277 6 4.9 10.3506 22.8202 7 5.9 9.3790 26.1514 6 6.9 8.7667 28.2868 7 7.9 8.6490 28.7347 6 9.0 8.5770 28.9220 7 10.0 8.4616 29.1673 6 11.0 8.4234 29.2631 7 11.9 8.3243 29.4582 7 13.0 8.2130 29.6745 7 14.0 8.1887 29.7311 7 14.9 8.1674 29.7746 6 15.9 8.1476 29.8154 7 16.9 8.0960 29.9108 6 18.0 8.0265 30.0413 8 19.0 7.9004 30.2589 7 20.0 7.8639 30.3310 7 21.0 7.8462 30.3634 7 22.0 7.7826 30.4680 7 23.0 7.7751 30.4840 7 24.0 7.7593 30.5088 7 24.9 7.7498 30.5258 7 25.9 7.7449 30.5348 8 26.9 7.7339 30.5543 9 28.0 7.7277 30.5656 9 29.0 7.7271 30.5664 9 30.0 7.7318 30.5575 10 31.0 7.7313 30.5585 10 32.0 7.7276 30.5660 10 33.0 7.7274 30.5659 10 33.5 7.7309 30.5646 1
