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 13.4090 17.0353 5 1.9 13.3174 17.1875 6 2.9 12.5612 19.5183 7 4.0 10.0061 26.2113 6 4.9 9.4584 28.0965 5 5.9 9.2633 28.5706 6 7.0 8.9326 29.1018 6 8.0 8.7741 29.3806 6 9.0 8.6795 29.5485 6 10.0 8.5891 29.6318 6 11.0 8.4019 29.8703 6 12.0 8.1778 30.1825 6 13.0 8.0506 30.3549 6 13.9 7.9911 30.4321 6 14.9 7.9745 30.4560 6 15.9 7.9497 30.4868 6 16.9 7.9264 30.5117 6 17.9 7.8718 30.5874 6 18.9 7.8448 30.6490 6 19.9 7.8285 30.6790 6 20.9 7.8233 30.6968 6 21.9 7.8205 30.7102 6 22.9 7.8167 30.7302 6 23.9 7.8107 30.7542 6 24.9 7.8039 30.7850 6 25.9 7.8013 30.8016 6 26.9 7.8039 30.8004 6 28.0 7.7952 30.8453 8 28.6 7.7956 30.8681 3
