Salinity was cleaned lightly. 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 1.0 11.7789 15.3042 9 1.9 11.7407 15.8989 9 3.0 11.7150 16.6963 7 4.0 11.5923 17.7270 8 5.0 11.3525 19.1190 8 6.0 10.2924 23.4111 7 6.9 9.6516 25.7984 6 7.9 9.2891 26.9387 7 9.0 8.9846 27.7144 7 10.0 8.8790 28.0027 7 11.0 8.6673 28.5840 7 12.0 8.3232 29.4613 7 13.0 8.2106 29.7791 7 14.0 8.1569 29.9158 6 14.9 8.1373 29.9688 6 15.9 8.0796 30.1190 6 17.0 8.0404 30.2327 7 18.0 8.0301 30.2655 6 19.0 8.0154 30.3029 6 20.0 7.9988 30.3503 7 21.0 7.9813 30.4102 6 22.0 7.9673 30.4528 7 23.0 7.9595 30.4705 6 23.9 7.9521 30.5003 7 24.9 7.9427 30.5681 7 25.9 7.9378 30.6270 7 26.9 7.9352 30.6570 6 27.9 7.9331 30.6760 7 28.9 7.9343 30.7040 6 29.9 7.9402 30.7252 7 31.0 7.9413 30.7470 6 32.0 7.9420 30.7700 7 33.0 7.9384 30.7852 6 33.9 7.9355 30.7918 7 34.9 7.9342 30.8056 7 35.9 7.9351 30.8318 7 36.9 7.9359 30.8554 7 37.9 7.9362 30.8658 7 38.9 7.9385 30.8754 7 39.9 7.9401 30.8865 7 40.9 7.9449 30.9052 7 41.9 7.9540 30.9246 7 42.8 7.9676 30.9443 4 44.0 7.9747 30.9478 7 45.0 7.9747 30.9540 7 45.9 7.9699 30.9650 7 46.9 7.9645 30.9719 8 47.9 7.9590 30.9754 8 48.9 7.9515 30.9799 8 49.9 7.9414 30.9882 8 50.9 7.9337 30.9999 8 51.9 7.9319 31.0027 7 52.9 7.9300 31.0091 8 53.9 7.9285 31.0186 7 54.9 7.9299 31.0229 8 56.0 7.9322 31.0254 8 57.0 7.9299 31.0377 8 57.6 7.9287 31.0429 3 59.0 7.9273 31.0475 4
