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 1.0 9.5999 29.2455 14 1.9 9.5307 29.2889 10 2.9 9.5807 29.2520 8 3.9 9.4520 29.3407 8 5.0 9.3001 29.4464 8 6.0 9.2275 29.5115 7 6.9 9.2173 29.5195 8 8.0 9.2142 29.5156 8 9.0 9.2193 29.5083 8 10.0 9.1187 29.6082 7 10.9 8.9737 29.7445 8 11.9 8.8343 29.8633 8 12.9 8.7542 29.9276 8 13.9 8.7631 29.9180 8 14.9 8.7489 29.9274 8 15.9 8.7398 29.9343 9 17.0 8.7354 29.9337 8 18.0 8.7934 29.8866 9 19.0 8.6514 29.9941 8 19.9 8.5704 30.0508 8 20.9 8.5109 30.0909 9 22.0 8.4551 30.1297 8 23.0 8.3542 30.2172 8 23.9 8.1289 30.4362 8 25.0 8.0767 30.4967 9 26.0 8.0809 30.4899 8 27.0 8.0529 30.5257 10 28.0 8.0250 30.5621 11 29.0 8.0167 30.5721 17
