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 9.1074 29.3806 4 1.9 9.0003 29.5526 9 3.0 8.8770 29.7820 7 4.0 8.6845 30.0230 6 4.9 8.5595 30.2762 6 6.0 8.5736 30.3477 7 6.9 8.5788 30.4084 6 7.9 8.4818 30.5481 6 8.9 8.4359 30.6225 6 9.9 8.4067 30.6609 6 10.9 8.4123 30.6740 6 12.0 8.4125 30.6893 7 13.0 8.3998 30.7091 6 14.0 8.3883 30.7266 5 14.9 8.3736 30.7528 6 15.9 8.3258 30.8128 6 17.0 8.2655 30.9116 6 18.0 8.2559 30.9445 6 19.0 8.2480 30.9885 6 20.0 8.2413 31.0166 6 21.0 8.2378 31.0252 6 22.0 8.2359 31.0300 7 23.0 8.2223 31.0543 6 24.0 8.2064 31.0852 6 25.0 8.2004 31.0993 7 26.0 8.1983 31.1072 6 27.0 8.1925 31.1181 6 28.0 8.1892 31.1236 6 29.0 8.1867 31.1283 6 29.9 8.1800 31.1360 6 30.9 8.1782 31.1398 7 32.0 8.1704 31.1552 6 33.0 8.1636 31.1748 7 34.0 8.0903 31.3263 6 35.0 7.9591 31.5892 8 35.8 7.9212 31.6732 6
