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 1.1 11.1231 13.4075 4 1.9 11.0098 14.8224 8 2.9 10.7615 18.4817 6 3.9 10.1793 23.9619 6 4.9 9.6717 27.0012 6 5.9 9.3436 28.0427 6 6.9 9.1025 28.6222 6 7.9 8.6572 29.4414 6 9.0 8.4668 29.8152 7 10.0 8.1734 30.2748 6 10.9 8.0608 30.4530 6 12.0 8.0160 30.5161 7 13.0 7.9582 30.5877 6 13.9 7.9286 30.6224 6 14.9 7.8883 30.6650 6 16.0 7.8644 30.6874 7 17.0 7.8509 30.7009 6 18.0 7.8500 30.7039 6 18.9 7.8484 30.7073 6 19.9 7.8472 30.7139 7 20.9 7.8406 30.7255 6 21.9 7.8242 30.7429 7 23.0 7.7993 30.7612 6 24.0 7.7539 30.8025 6 25.0 7.7400 30.8150 6 26.0 7.7239 30.8217 6 27.0 7.7079 30.8302 6 28.0 7.7066 30.8322 6 29.0 7.7057 30.8347 6 29.9 7.6909 30.8395 6 30.9 7.6668 30.8534 6 32.0 7.6478 30.8701 6 33.0 7.6398 30.8806 6 34.0 7.6283 30.8939 6 35.0 7.5972 30.9217 6 36.0 7.5651 30.9490 6 37.0 7.5594 30.9528 7 37.8 7.5608 30.9550 6
