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 13.8323 10.6515 5 1.9 13.4684 11.1765 8 3.0 13.1121 11.6613 8 3.9 12.0306 14.3364 7 4.9 10.9142 19.7633 7 6.0 9.8734 24.7261 7 6.9 9.2280 27.1460 6 7.9 8.9841 28.1061 7 8.9 8.9143 28.3632 7 9.9 8.7907 28.6649 6 10.9 8.3921 29.4141 7 12.0 8.0627 29.9958 7 13.0 7.9593 30.1790 7 13.9 7.8465 30.3620 7 14.9 7.7965 30.4504 7 15.9 7.7468 30.5370 7 16.9 7.7125 30.5984 8 17.9 7.7037 30.6140 8 18.9 7.6785 30.6543 7 19.9 7.6614 30.6843 7 21.0 7.6352 30.7277 7 22.0 7.6220 30.7500 7 23.0 7.6158 30.7598 7 24.0 7.5996 30.7851 6 24.9 7.5816 30.8132 7 25.9 7.5715 30.8296 7 27.0 7.5663 30.8379 7 28.0 7.5648 30.8400 7 28.9 7.5647 30.8400 7 30.0 7.5643 30.8406 7 31.0 7.5627 30.8424 6 31.9 7.5622 30.8430 7 32.9 7.5616 30.8437 7 33.9 7.5613 30.8438 7 34.9 7.5606 30.8447 7 35.9 7.5591 30.8475 7 36.9 7.5575 30.8506 8 38.0 7.5534 30.8582 6 38.9 7.5495 30.8656 7 40.0 7.5461 30.8722 9 41.0 7.5450 30.8761 10 41.8 7.5455 30.8791 6
