Downcast data were heavily corrupted for some casts; for all but one of those, the upcast data were better and were chosen for archiving. Whenever upcast data were selected a special note was made in the header. 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 11.9145 15.1457 9 2.0 11.8682 15.9819 10 2.9 11.8314 16.6089 8 3.9 11.8104 16.8359 9 5.0 11.6473 17.6640 9 6.0 11.0618 20.3342 9 7.0 10.4776 22.7800 9 8.0 9.7514 25.3490 9 9.0 9.5179 26.1982 8 10.0 8.9593 27.7736 9 11.0 8.4866 29.0379 9 11.9 8.3100 29.5089 8 12.9 8.2048 29.7821 9 14.0 8.1846 29.8365 9 15.0 8.1416 29.9415 9 16.0 8.1049 30.0363 8 16.9 8.0745 30.1203 9 18.0 8.0544 30.1744 9 19.0 8.0450 30.2015 9 20.0 8.0421 30.2096 8 20.9 8.0383 30.2190 9 21.9 8.0312 30.2394 9 23.0 8.0281 30.2499 9 23.9 8.0173 30.2748 8 24.9 8.0119 30.2848 9 26.0 8.0060 30.2982 9 26.9 7.9601 30.4230 8 27.9 7.9232 30.5460 9 28.9 7.9131 30.6004 9 29.9 7.9075 30.6501 9 31.0 7.9046 30.6891 10 32.0 7.9034 30.7041 9 32.9 7.9027 30.7132 9 34.0 7.8996 30.7301 10 35.0 7.8886 30.7764 9 36.0 7.8898 30.8414 10 37.0 7.8892 30.8666 9 38.0 7.8897 30.8720 9 39.0 7.8906 30.8755 10 39.7 7.8926 30.8780 4
