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 12.9039 19.5622 5 1.9 11.9540 21.2643 6 3.0 10.5592 24.3687 7 4.0 9.9454 26.0930 6 4.9 9.3778 27.3250 6 5.9 8.8132 28.5334 6 6.9 8.5801 29.0450 6 7.9 8.4607 29.3326 6 8.9 8.2978 29.6518 6 9.9 8.1931 29.8763 6 10.9 8.1390 29.9975 6 11.9 8.0218 30.1962 6 13.0 7.8586 30.4880 6 13.9 7.7994 30.6265 6 15.0 7.7670 30.6947 7 16.0 7.7642 30.7036 6 16.9 7.7590 30.7134 5 18.0 7.7470 30.7330 6 19.0 7.7324 30.7652 6 20.0 7.7181 30.7992 7 21.0 7.7117 30.8198 6 22.0 7.7069 30.8379 7 22.9 7.7038 30.8616 6 23.9 7.7039 30.8674 7 24.9 7.7042 30.8718 7 25.9 7.7040 30.8746 7 27.0 7.7020 30.8825 6 27.9 7.6946 30.8981 7 29.0 7.6929 30.9028 7 30.0 7.6869 30.9184 6 30.9 7.6862 30.9234 7 32.0 7.6840 30.9341 6 32.9 7.6740 30.9590 6 34.0 7.6695 30.9689 7 35.0 7.6559 30.9872 6 35.9 7.6355 31.0275 7 37.0 7.6231 31.0595 6 38.0 7.6170 31.0778 7 39.0 7.6130 31.0918 6 40.0 7.6035 31.1217 8 41.0 7.5943 31.1573 9
