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 12.0171 11.9480 9 2.0 11.3428 15.4935 10 3.0 10.9471 17.9601 9 4.0 10.7373 19.4116 8 5.0 10.3844 21.4123 9 5.9 10.1790 22.8216 8 6.9 9.2496 26.2119 8 7.9 8.7440 28.1448 9 9.0 8.6582 28.3867 8 10.0 8.5918 28.5154 8 11.0 8.5237 28.6739 8 12.0 8.4295 28.9187 8 12.9 8.3120 29.1877 7 13.9 8.2516 29.3470 9 14.9 8.2144 29.4886 8 15.9 8.1633 29.5731 9 17.0 8.0752 29.7222 8 18.0 7.9873 29.9144 8 19.0 7.9397 30.0301 8 20.0 7.8884 30.1538 8 21.0 7.8621 30.2263 8 22.0 7.8534 30.2465 7 22.9 7.8523 30.2490 7 23.9 7.8504 30.2521 7 25.0 7.8446 30.2650 8 26.0 7.8418 30.2751 7 27.0 7.8405 30.2800 8 28.0 7.8393 30.2869 8 29.0 7.8185 30.3346 8 29.9 7.7991 30.3964 7 30.9 7.7782 30.4494 8 31.9 7.7624 30.4923 8 33.0 7.7527 30.5281 8 34.0 7.7504 30.5390 8 35.0 7.7514 30.5350 9 36.0 7.7517 30.5427 10 36.6 7.7447 30.5640 3
