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 12.6526 7.5255 5 2.0 12.5526 7.9828 9 2.9 12.3516 8.9629 7 4.0 11.5086 12.4718 6 5.0 10.3670 18.2917 6 6.0 9.2137 24.1859 5 6.9 8.6730 26.9464 6 7.9 8.5180 27.7303 6 8.9 8.4427 28.0383 6 9.9 8.3716 28.3229 6 10.9 8.2564 28.7407 6 12.0 8.1756 29.0434 6 12.9 8.0804 29.3586 6 13.9 7.9432 29.7837 6 14.9 7.8892 29.9780 6 16.0 7.8840 30.0020 6 16.9 7.8702 30.0439 5 17.9 7.8554 30.0901 6 19.0 7.8426 30.1323 6 20.0 7.8372 30.1528 6 21.0 7.8280 30.1789 6 21.9 7.8179 30.2061 5 22.9 7.8066 30.2413 6 23.9 7.8003 30.2585 6 25.0 7.7941 30.2761 6 25.9 7.7903 30.2876 5 26.9 7.7846 30.3016 6 28.0 7.7837 30.3042 6 29.0 7.7763 30.3229 5 29.9 7.7695 30.3418 6 31.0 7.7594 30.3682 6 32.0 7.7581 30.3760 6 33.0 7.7454 30.4095 6 34.0 7.7357 30.4381 6 35.0 7.7355 30.4436 5 36.0 7.7322 30.4550 6 37.0 7.7313 30.4595 6 38.0 7.7223 30.4862 7 38.7 7.7156 30.5119 4
