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 0.7 11.3123 24.4929 12 2.0 10.4379 26.0895 10 2.9 10.3529 26.4045 9 3.9 10.2115 26.7051 9 4.9 10.0424 26.9957 8 5.9 9.8952 27.2043 8 6.9 9.7182 27.4684 8 7.9 9.3919 28.0300 8 9.0 9.2530 28.2998 8 10.0 9.1707 28.4056 7 10.9 8.8570 28.8081 8 12.0 8.4813 29.3259 8 12.9 8.4311 29.4369 7 13.9 8.4581 29.4830 8 15.0 8.4378 29.5444 7 16.0 8.3558 29.6630 8 16.9 8.1756 29.9246 7 17.9 8.1922 29.9949 8 19.0 8.1896 30.0518 8 20.0 8.1731 30.1024 7 20.9 8.1508 30.1475 8 22.0 8.1255 30.2034 8 23.0 8.1044 30.2396 7 24.0 8.0831 30.2796 8 25.0 8.0687 30.3129 8 26.0 8.0577 30.3337 8 27.0 8.0413 30.3643 9 28.0 8.0163 30.4129 11 28.9 8.0048 30.4772 14
