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 10.1644 15.4554 5 1.9 9.9703 22.0417 8 3.0 9.6044 25.2985 7 3.9 9.2803 26.6129 6 4.9 8.6731 28.3384 6 6.0 8.5342 28.8718 7 6.9 8.4419 29.1383 6 7.9 8.2134 29.6363 6 8.9 8.0991 29.9297 6 10.0 8.0357 30.0811 6 11.0 7.9879 30.1865 5 11.9 7.9597 30.2500 6 13.0 7.9255 30.3205 7 14.0 7.8984 30.3787 6 15.0 7.8693 30.4404 6 16.0 7.8442 30.4956 5 16.9 7.8315 30.5250 6 17.9 7.8159 30.5571 7 19.0 7.7959 30.5960 6 20.0 7.7788 30.6309 5 20.9 7.7624 30.6601 6 22.0 7.7515 30.6794 6 23.0 7.7424 30.6974 6 23.9 7.7292 30.7237 6 24.9 7.7020 30.7736 7 26.0 7.6808 30.8021 6 27.0 7.6759 30.8079 6 27.9 7.6713 30.8149 6 28.9 7.6670 30.8202 7 29.9 7.6517 30.8419 7 30.9 7.6334 30.8709 7 32.0 7.6244 30.8867 7 32.9 7.6209 30.8920 7 33.9 7.6154 30.9013 6 34.9 7.6120 30.9116 7 36.0 7.6090 30.9182 7 37.0 7.6062 30.9270 6 37.9 7.6052 30.9356 6 39.0 7.5996 30.9471 7 40.0 7.5933 30.9623 7 40.7 7.5821 30.9834 5
