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 0.9 12.1145 11.7672 10 2.0 11.4432 14.7740 10 3.0 10.4858 19.7170 9 4.0 10.3206 20.8952 9 5.0 10.0775 22.2596 8 6.0 9.5943 24.6967 9 6.9 9.4271 25.5998 8 7.9 9.2317 26.4690 9 9.0 8.9588 27.5031 8 10.0 8.3174 29.0799 9 11.0 8.2228 29.3518 9 12.0 8.1900 29.4255 9 13.0 8.1731 29.4534 9 14.0 8.1624 29.4720 9 15.0 8.1488 29.5011 9 16.0 8.1119 29.5870 9 17.0 8.0631 29.7030 9 18.0 7.9803 29.8881 9 18.9 7.9431 29.9735 9 20.0 7.9435 29.9715 10 20.9 7.9135 30.0415 8 21.9 7.8671 30.1588 9 22.9 7.8488 30.1930 9 23.9 7.8393 30.2287 9 25.0 7.8151 30.2953 9 26.0 7.8019 30.3166 8 26.9 7.7895 30.3604 8 27.9 7.7852 30.4008 8 28.9 7.7755 30.4374 9 29.9 7.7668 30.4742 9 31.0 7.7630 30.4909 10 32.0 7.7614 30.4977 10 33.0 7.7530 30.5238 10 34.0 7.7485 30.5364 10 35.0 7.7481 30.5374 10 36.0 7.7475 30.5388 10 37.0 7.7462 30.5422 10 38.0 7.7444 30.5473 10 39.0 7.7431 30.5515 10 39.9 7.7418 30.5558 9
