There were problems with the temperature and salinity data for a few casts that may be due to a corroded bulkhead connector. 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 1.1 12.7729 18.9842 7 1.9 11.7174 23.0073 8 2.9 11.2023 24.5130 7 3.9 10.3613 26.4109 8 4.9 9.9609 27.3019 7 5.9 9.7785 27.6662 7 6.9 9.3872 28.3108 7 7.9 9.2332 28.5649 6 8.9 9.0539 28.7948 7 9.9 8.7769 29.1096 6 10.9 8.7247 29.1660 7 11.9 8.6487 29.2209 6 12.9 8.5095 29.3255 7 13.9 8.4228 29.4104 6 15.0 8.2797 29.5290 7 15.9 8.0820 29.6668 6 16.9 7.9182 29.7711 7 17.9 7.7270 29.9287 6 18.9 7.5932 30.0526 7 20.0 7.5864 30.1105 7 21.0 7.5851 30.1445 6 21.9 7.5970 30.2309 7 22.9 7.5983 30.2697 6 23.9 7.5914 30.3142 7 25.0 7.5846 30.3326 6 25.9 7.5846 30.3475 7 27.0 7.6035 30.3874 7 28.0 7.7145 30.4963 7 29.0 7.7447 30.5357 7 30.0 7.7548 30.5520 7 31.0 7.7469 30.5662 6 31.9 7.7773 30.5995 7 33.0 7.8082 30.6330 8 34.0 7.8111 30.6451 8 35.0 7.8135 30.6550 9 36.0 7.8322 30.6932 9 37.0 7.8356 30.7115 10 38.0 7.8733 30.7504 10 38.7 7.8971 30.7750 4
