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 15.2507 18.7646 5 1.9 14.3499 19.9893 8 2.9 11.7780 24.2512 6 3.9 10.6400 26.5229 5 4.9 9.5015 28.2899 6 5.9 8.9799 29.2627 5 6.9 8.8232 29.6002 5 7.9 8.6637 29.8968 5 8.9 8.5900 30.0515 5 9.9 8.5082 30.2271 6 10.9 8.4641 30.3321 5 12.0 8.4431 30.3804 5 13.0 8.4211 30.4381 5 14.0 8.3760 30.5423 5 14.9 8.3486 30.6181 6 15.9 8.3388 30.6529 6 17.0 8.3231 30.7397 9
