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 13.3851 17.6182 5 1.9 12.7772 18.8573 7 2.9 10.5200 23.8569 7 4.0 9.3231 26.9774 7 5.0 8.3172 29.2336 6 6.0 8.0819 29.8237 6 7.0 8.0322 29.9423 6 8.0 7.9902 30.0395 6 9.0 7.8865 30.2599 7 9.9 7.8370 30.3733 7 10.9 7.8103 30.4249 7 12.0 7.8025 30.4445 6 13.0 7.7711 30.5119 6 14.0 7.7261 30.6075 5 14.9 7.7157 30.6342 6 15.9 7.7070 30.6523 6 16.9 7.7008 30.6656 6 17.9 7.6985 30.6702 6 18.9 7.6955 30.6760 6 20.0 7.6901 30.6873 6 20.9 7.6775 30.7136 6 21.9 7.6644 30.7445 7 23.0 7.6405 30.7941 6 24.0 7.6326 30.8151 6 25.0 7.6125 30.8565 6 25.9 7.6043 30.8758 6 27.0 7.5924 30.9005 7 28.0 7.5861 30.9153 6 28.9 7.5839 30.9230 7 30.0 7.5822 30.9286 6 30.9 7.5799 30.9340 6 31.9 7.5762 30.9415 7 32.9 7.5741 30.9478 6 33.9 7.5717 30.9572 7 35.0 7.5683 30.9662 7 36.0 7.5628 30.9844 6 36.9 7.5544 31.0116 7 38.0 7.5487 31.0291 7 39.0 7.5455 31.0388 6 39.9 7.5462 31.0376 7 41.0 7.5461 31.0407 10
