SeaCat salinity is prone to error due to mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. These errors are likely to be much larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05units in areas of high gradients. However, this cruise had large gradients only at the surface and the descent rate was generally very steady, so the errors should be much smaller than that. ---------------------------------------------------------------------- !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure :T0:C0 er_o ! ~bin ! _rec ! ords !------ -------- -------- ---- *END OF HEADER 1.2 12.2825 24.6260 5 2.0 12.2785 24.7612 8 3.0 12.2199 25.0501 7 3.9 11.5638 26.1205 7 4.9 10.1818 28.1610 7 5.9 9.0311 29.7824 6 6.9 8.7982 30.2948 6 8.0 8.7290 30.4514 6 8.9 8.6851 30.5461 5 9.9 8.5992 30.7123 6 11.0 8.5496 30.8330 6 11.9 8.5236 30.9004 5 12.9 8.5055 30.9219 6 13.9 8.4802 30.9385 5 14.9 8.4551 30.9497 7 15.9 8.4448 30.9535 7 17.0 8.4275 30.9765 5 18.0 8.4246 30.9906 6 19.0 8.4307 30.9929 6 20.0 8.4277 30.9984 6 21.0 8.4296 31.0102 6 21.9 8.4258 31.0398 5 22.9 8.4101 31.0713 7 24.0 8.4089 31.0895 6 25.0 8.4104 31.0993 6 26.0 8.4069 31.1027 5 27.0 8.3967 31.1071 6 28.0 8.3804 31.1269 5 29.0 8.3668 31.1526 5 30.0 8.3599 31.1733 6 31.0 8.3546 31.1950 5 31.9 8.3502 31.2070 5 32.9 8.3407 31.2227 6 34.0 8.3368 31.2302 6 35.0 8.3249 31.2501 6 36.0 8.3131 31.2656 6 37.0 8.2882 31.2987 5 38.0 8.2718 31.3247 7 39.0 8.2637 31.3370 6 40.0 8.2598 31.3437 8 40.5 8.2593 31.3474 2
