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 13.6874 21.3723 5 1.9 13.6767 21.4618 7 3.0 13.3744 22.0419 7 4.0 11.9644 24.1295 6 4.9 10.4923 26.7920 10 5.9 9.8415 27.9345 10 6.9 9.4548 28.5393 9 7.9 9.1154 29.1040 10 8.9 8.9916 29.3198 8 9.9 8.9233 29.4990 8 10.9 8.7284 29.8482 7 12.0 8.3880 30.3189 7 13.0 8.3029 30.4588 8 14.0 8.2482 30.5558 8 14.9 8.2153 30.6068 7 15.9 8.1856 30.6672 8 17.0 8.1785 30.6870 6 17.9 8.1732 30.6904 6 19.0 8.1643 30.6923 7 20.0 8.1249 30.7189 7 21.0 8.0878 30.7636 7 22.0 8.0641 30.7969 7 23.0 8.0487 30.8313 7 24.0 8.0310 30.8652 7 25.0 8.0297 30.8761 7 26.0 8.0420 30.8906 7 26.9 8.0451 30.9098 7 27.9 7.9972 30.9433 8 29.0 7.9771 30.9697 6 29.9 7.9716 31.0116 7 30.9 7.9526 31.0432 7 31.9 7.9564 31.0628 6 32.9 7.9538 31.0828 7 34.0 7.9759 31.0960 7 35.0 7.9578 31.1250 7 35.9 7.9716 31.1475 7 37.0 7.9124 31.1712 8 38.0 7.8946 31.1778 7 38.9 7.8980 31.1875 7 39.9 7.9011 31.1987 7 40.8 7.9087 31.2366 6
