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 0.4 8.2682 28.2000 1 0.9 8.2684 28.2393 10 2.0 8.2694 28.2365 10 3.0 8.3070 28.3176 10 4.0 8.3239 28.3735 10 4.9 8.3245 28.3789 10 5.9 8.3385 28.3956 10 6.9 8.3241 28.4140 10 7.9 8.3707 28.4424 10 8.9 8.3392 28.5024 10 9.9 8.2302 28.7368 10 10.9 8.1538 29.0145 10 11.9 8.0765 29.2306 10 12.9 8.0532 29.3142 10 13.9 7.9831 29.5382 10 14.9 7.9236 29.7375 10 15.9 7.8494 29.9587 10 17.0 7.8145 30.0605 10 18.0 7.7980 30.1039 10 19.0 7.7785 30.1490 10 20.0 7.7734 30.1616 10 21.0 7.7694 30.1723 10 22.0 7.7642 30.1886 10 23.0 7.7361 30.2576 10
