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 1.0 8.3166 28.3587 9 2.0 8.3112 28.3606 10 3.0 8.3150 28.3605 10 4.0 8.3138 28.3607 10 4.9 8.3135 28.3602 10 5.9 8.3148 28.3620 10 6.9 8.3209 28.3730 10 7.9 8.3343 28.3986 10 8.9 8.3133 28.5163 10 9.9 8.2895 28.5931 10 10.9 8.2288 28.7289 10 11.9 8.1528 28.9676 10 12.9 7.9370 29.6570 10 13.9 7.8619 29.9030 10 14.9 7.8386 29.9783 10 15.9 7.8336 29.9972 10 17.0 7.8237 30.0282 10 18.0 7.7948 30.1063 10 19.0 7.7598 30.1958 10 20.0 7.7495 30.2227 10 21.0 7.7446 30.2341 10 22.0 7.7311 30.2650 10 23.0 7.7006 30.3292 10 24.0 7.6783 30.3757 10 25.0 7.6634 30.4063 10 26.0 7.6609 30.4116 10 27.0 7.6532 30.4275 10 27.5 7.6462 30.4424 1
