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 8.9056 27.9648 5 1.9 8.8631 28.0975 9 3.0 8.7640 28.4372 8 4.0 8.6508 28.8556 7 4.9 8.5084 29.3405 6 5.9 8.4197 29.6599 7 6.9 8.3548 29.8869 7 7.9 8.2420 30.2192 8 9.0 8.1460 30.4667 7 10.0 8.1225 30.5149 7 11.0 8.1188 30.5223 7 11.9 8.1115 30.5356 6 12.9 8.1089 30.5433 7 14.0 8.0963 30.5686 7 15.0 8.0921 30.5805 6 16.0 8.0858 30.6003 6 17.0 8.0821 30.6114 6 18.0 8.0786 30.6152 6 18.9 8.0767 30.6186 6 19.9 8.0703 30.6319 6 20.9 8.0658 30.6443 7 22.0 8.0669 30.6448 6 23.0 8.0639 30.6525 6 24.0 8.0632 30.6556 6 25.0 8.0585 30.6684 7 26.0 8.0222 30.7433 6 27.0 7.9868 30.8177 6 28.0 7.9399 30.9025 7 29.0 7.9167 30.9437 6 29.9 7.9079 30.9606 7 30.9 7.9046 30.9678 7 31.9 7.9049 30.9674 7 33.0 7.9034 30.9707 7 34.0 7.8988 30.9797 6 35.0 7.8904 30.9967 7 36.0 7.8640 31.0509 7 37.0 7.8415 31.1004 6 37.9 7.8360 31.1166 7 39.0 7.8199 31.1448 7 40.0 7.8182 31.1480 7 40.9 7.8261 31.1342 8
