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 12.3834 24.0212 5 1.9 12.0833 24.5628 7 2.9 11.6914 25.4421 8 3.9 10.1595 28.1658 7 4.9 9.3695 29.7079 6 5.9 9.0689 30.3035 7 7.0 8.8676 30.6153 7 8.0 8.8419 30.6579 6 9.0 8.8283 30.6740 7 10.0 8.8029 30.7060 6 10.9 8.7652 30.7570 7 11.9 8.7366 30.7969 6 13.0 8.7266 30.8123 7 14.0 8.7239 30.8177 6 15.0 8.7214 30.8222 6 16.0 8.6915 30.8642 6 17.0 8.6610 30.9097 6 18.0 8.6191 30.9710 7 19.0 8.6041 30.9955 6 20.0 8.6019 30.9990 6 20.9 8.6013 30.9997 6 21.9 8.6063 30.9932 6 23.0 8.6037 30.9964 7 24.0 8.6011 31.0000 6 24.9 8.5982 31.0041 7 25.9 8.5917 31.0158 7 26.9 8.5605 31.0669 6 27.9 8.5304 31.1244 7 29.0 8.5254 31.1393 6 30.0 8.4758 31.2102 6 30.9 8.4248 31.2619 7 32.0 8.4074 31.2699 7 33.0 8.3881 31.2850 7 34.0 8.3643 31.3085 6 34.9 8.3477 31.3250 7 35.9 8.3356 31.3390 6 36.9 8.3163 31.3615 7 37.9 8.2584 31.4265 7 38.9 8.2228 31.4708 7 40.0 8.1996 31.4992 8 40.5 8.1655 31.5376 1
