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 13.5634 17.0663 5 1.9 13.2582 17.7790 7 3.0 11.6583 22.6607 6 3.9 10.6800 26.1996 5 4.9 10.0381 27.5817 6 6.0 9.3615 28.6860 6 7.0 9.2390 28.9277 5 8.0 8.9923 29.2495 6 9.0 8.8800 29.3995 5 10.0 8.7052 29.6192 5 10.9 8.3967 30.0195 5 11.9 8.3435 30.1162 6 12.9 8.1881 30.3209 5 13.9 8.1594 30.3656 6 15.0 8.1260 30.4131 6 15.9 8.0386 30.5324 5 16.9 7.9759 30.6271 6 18.0 7.9155 30.7223 6 19.0 7.8962 30.7441 5 19.9 7.8801 30.7536 6 20.9 7.8747 30.7551 6 22.0 7.8622 30.7687 6 23.0 7.8522 30.7787 5 24.0 7.8319 30.7952 5 25.0 7.8176 30.8101 6 26.0 7.8028 30.8357 5 27.0 7.7937 30.8599 6 28.0 7.7828 30.8857 5 29.0 7.7768 30.9063 6 30.0 7.7722 30.9205 5 30.9 7.7719 30.9212 6 32.0 7.7723 30.9200 6 33.0 7.7648 30.9310 5 33.9 7.7566 30.9346 6 35.0 7.7523 30.9335 6 35.9 7.7519 30.9316 5 36.9 7.7418 30.9349 6 37.9 7.7380 30.9380 6 38.9 7.7435 30.9436 7 40.0 7.7375 30.9579 7 40.8 7.7391 30.9664 6
