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 10.2936 8.7147 5 2.0 10.3235 9.0656 8 3.0 10.3908 13.8397 8 4.0 9.2372 26.8171 7 4.9 8.9695 28.9589 7 5.9 8.8408 29.2331 8 6.9 8.6095 29.6302 8 8.0 8.4107 29.9466 7 8.9 8.4015 29.9774 8 9.9 8.2669 30.1709 7 10.9 8.0803 30.4048 7 11.9 8.0357 30.4665 7 12.9 8.0189 30.4892 7 13.9 7.9712 30.5415 6 14.9 7.9266 30.5897 6 15.9 7.9155 30.6064 7 17.0 7.9064 30.6288 6 18.0 7.8527 30.6784 7 19.0 7.8291 30.7037 7 20.0 7.8120 30.7241 8 21.0 7.7638 30.7878 7 22.0 7.7267 30.8430 6 23.0 7.7184 30.8598 8 24.0 7.7126 30.8756 7 25.0 7.6864 30.9051 7 26.0 7.6738 30.9297 7 27.0 7.6653 30.9627 6 28.0 7.7050 30.9734 7 29.0 7.6806 30.9919 6 29.9 7.6521 30.9942 6 30.9 7.6421 30.9964 7 31.9 7.6535 31.0043 7 33.0 7.6960 31.0175 8 33.9 7.6767 31.0306 7 34.9 7.6898 31.0361 7 35.9 7.6911 31.0555 7 36.9 7.6381 31.0830 6 37.9 7.6180 31.0879 6 38.9 7.6053 31.0911 7 40.0 7.5929 31.0984 8 40.7 7.5894 31.1012 5
