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 11.4757 13.5619 5 1.9 11.5502 16.9302 7 2.9 11.3054 18.7891 6 3.9 10.7124 21.2745 6 4.9 9.5339 25.3995 6 5.9 9.1483 27.0605 6 6.9 8.8079 28.0494 6 7.9 8.3500 29.2631 6 9.0 8.1810 29.7195 6 10.0 8.0637 29.9996 5 10.9 8.0441 30.0629 6 11.9 8.0090 30.1479 6 12.9 7.9334 30.3128 6 14.0 7.8943 30.4132 7 14.9 7.8650 30.4828 6 15.9 7.8421 30.5381 7 17.0 7.8322 30.5611 7 17.9 7.8241 30.5824 7 18.9 7.7953 30.6493 6 19.9 7.7908 30.6656 6 21.0 7.7910 30.6658 6 21.9 7.7857 30.6785 6 23.0 7.7764 30.7051 7 23.9 7.7577 30.7538 6 24.9 7.7361 30.8128 7 26.0 7.7348 30.8201 6 27.0 7.7330 30.8260 6 28.0 7.7257 30.8478 6 29.0 7.7145 30.8825 6 30.0 7.7125 30.8922 6 31.0 7.7096 30.9124 6 32.0 7.7083 30.9280 5 33.0 7.7098 30.9354 7 34.0 7.7102 30.9540 6 34.9 7.7062 30.9822 6 35.9 7.6985 31.0102 7 37.0 7.6899 31.0383 9 37.8 7.6868 31.0504 6
