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. There was a dissolved oxygen sensor mounted on the CTD, but there was no signal recorded so the channel was removed. **************************************************************************** !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure :T0:C0 er_o ! ~bin ! _rec ! ords !------ -------- -------- ---- *END OF HEADER 1.3 8.5071 28.0035 2 2.0 8.5307 28.0427 10 3.0 8.5561 28.0718 10 4.0 8.5560 28.0725 10 4.9 8.5484 28.0767 10 5.9 8.5406 28.0813 10 6.8 8.5399 28.0826 8 8.0 8.5541 28.0898 3 8.9 8.5585 28.0990 10 9.9 8.5627 28.1074 10 10.9 8.5605 28.1171 10 11.9 8.5449 28.1443 10 12.9 8.5037 28.2062 10 13.9 8.3102 28.5844 10 14.9 8.1232 28.9731 10 15.9 7.9774 29.4546 10 17.0 7.8729 29.8018 10 18.0 7.8263 29.9413 10 19.0 7.8109 29.9806 10 19.5 7.8110 29.9816 1
