Many cast files were heavily corrupted and unusable. For some the downcast section was corrupted, but the upcast was better. There was no salinity calibration sampling; no recalibration was applied. SeaCat salinity is prone to error due to a mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. Such errors are likely to be larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05 units in areas of high gradients. **************************************************************************** !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure :T0:C0 er_o ! ~bin ! _rec ! ords !------ -------- -------- ---- *END OF HEADER 0.9 13.4521 21.0451 23 1.9 12.4098 23.3560 8 2.9 10.9318 26.5632 5 3.9 10.4460 27.4925 5 4.9 9.8327 28.2586 4 6.0 9.0953 29.0613 4 6.9 8.6646 29.5201 3 7.9 8.5955 29.6140 4 8.9 8.5537 29.6679 4 10.0 8.5079 29.7219 4 11.0 8.4473 29.7897 4 12.0 8.4037 29.8482 5 13.0 8.3549 29.9226 4 14.0 8.2796 30.0283 7 14.8 8.2630 30.0504 9 15.9 8.2462 30.0713 9 17.0 8.2256 30.1125 5 17.9 8.1797 30.1943 3 18.9 8.1231 30.2940 4 19.9 8.0950 30.3516 3 21.0 8.0869 30.3722 4 22.1 8.0821 30.3837 3 23.0 8.0789 30.3935 3 24.0 8.0735 30.4101 3 24.9 8.0652 30.4359 3 25.9 8.0524 30.4750 3 26.8 8.0382 30.5225 3 28.0 8.0182 30.5918 4 29.0 8.0054 30.6449 3 30.0 8.0024 30.6685 3 30.9 8.0010 30.6817 3 31.9 7.9995 30.6932 3 33.0 7.9987 30.7048 4 34.1 7.9976 30.7149 3 35.0 7.9970 30.7226 3 35.9 7.9969 30.7303 3 37.0 7.9959 30.7404 4 38.0 7.9940 30.7569 3 39.0 7.9895 30.7855 4 40.0 7.9831 30.8234 3 40.9 7.9798 30.8448 4 42.0 7.9798 30.8529 4 43.1 7.9767 30.8720 4 44.1 7.9722 30.8956 4 44.8 7.9686 30.9142 2 46.3 7.9641 30.9287 1 46.9 7.9640 30.9286 7
