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 13.8271 10.7429 4 2.0 13.5126 12.0709 10 2.9 12.2154 18.4973 7 3.9 10.9327 25.4139 8 4.9 10.1810 27.4738 6 5.9 9.8347 28.2812 7 6.9 9.5955 28.6753 6 7.9 9.2289 29.1524 6 8.9 8.9835 29.4561 7 9.9 8.7816 29.6837 6 10.9 8.6749 29.8123 7 11.9 8.5822 29.9213 5 12.9 8.4852 30.0431 6 13.9 8.3758 30.1944 6 15.0 8.3159 30.2992 6 15.9 8.2697 30.3608 6 16.9 8.2084 30.4326 6 17.9 8.0977 30.5501 6 19.0 8.0598 30.5921 6 20.0 8.0408 30.6077 6 21.0 7.9871 30.6482 6 21.9 7.9290 30.7114 5 22.9 7.8874 30.7692 6 24.0 7.8399 30.8378 6 25.0 7.8268 30.8664 6 26.0 7.8204 30.8831 5 26.9 7.8159 30.8987 5 27.9 7.8085 30.9217 6 28.9 7.8068 30.9374 5 30.0 7.7994 30.9535 6 31.0 7.7901 30.9668 5 31.9 7.7885 30.9700 5 32.9 7.7801 30.9833 6 33.9 7.7655 31.0056 6 35.0 7.7540 31.0202 6 36.0 7.7452 31.0317 6 37.0 7.7302 31.0493 6 38.0 7.7240 31.0570 6 38.9 7.7154 31.0698 6 40.0 7.7003 31.0916 9 40.7 7.6855 31.1171 2
