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 14.4865 14.4672 5 1.9 13.5521 17.7941 7 2.9 12.3599 21.5100 6 4.0 10.8943 25.5933 6 4.9 9.9660 27.4947 5 5.9 9.2417 28.8134 6 6.9 9.0056 29.2614 5 7.9 8.8309 29.5274 6 8.9 8.7344 29.6812 6 10.0 8.6823 29.7558 6 11.0 8.6562 29.7896 6 12.0 8.6318 29.8344 5 12.9 8.5990 29.9108 6 13.9 8.4999 30.0688 6 15.0 8.4620 30.1543 6 16.0 8.4431 30.2064 5 16.9 8.3910 30.2783 6 17.9 8.3457 30.3473 6 18.9 8.2709 30.4640 5 19.9 8.2343 30.5226 6 21.0 8.2108 30.5679 6 22.0 8.1770 30.6229 6 23.0 8.1173 30.6842 5 23.9 8.0739 30.7246 6 25.0 7.9884 30.7934 6 26.0 7.9387 30.8289 6 27.0 7.9187 30.8448 5 27.9 7.9096 30.8527 6 29.0 7.8892 30.8710 6 30.0 7.8836 30.8768 5 30.9 7.8627 30.9008 6 32.0 7.8233 30.9460 6 33.0 7.8026 30.9759 6 34.0 7.8032 30.9878 6 35.0 7.7963 31.0040 6 36.0 7.7887 31.0161 6 37.0 7.7879 31.0287 7 38.0 7.7863 31.0371 6 39.0 7.7640 31.0575 7 40.0 7.7551 31.0754 7 40.8 7.7528 31.0844 5
