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 12.4627 7.9190 5 1.9 12.5356 8.3622 8 3.0 12.3841 8.9189 7 3.9 12.1267 10.0224 6 4.9 11.3369 14.0081 7 5.9 9.9356 20.6474 6 6.9 9.1099 24.8218 7 8.0 8.4334 27.7708 7 8.9 8.2274 28.7106 6 9.9 8.1844 28.9027 7 10.9 8.0969 29.2127 7 11.9 7.9983 29.5441 6 12.9 7.9628 29.6758 7 14.0 7.9562 29.7006 7 14.9 7.9477 29.7246 6 15.9 7.9450 29.7377 6 16.9 7.9237 29.8034 6 18.0 7.8742 29.9661 7 19.0 7.8251 30.1280 6 20.0 7.8189 30.1552 6 21.0 7.8100 30.1823 6 22.0 7.7998 30.2145 6 23.0 7.7893 30.2435 6 24.0 7.8048 30.2012 6 24.9 7.8038 30.2000 5 25.9 7.8026 30.2036 6 27.0 7.8024 30.2047 6 27.9 7.8001 30.2130 6 29.0 7.7768 30.2896 7 30.0 7.6985 30.5151 6 31.0 7.6680 30.6206 6 32.0 7.6527 30.6691 6 33.0 7.6315 30.7297 7 34.0 7.6181 30.7721 6 34.9 7.6119 30.7900 7 36.0 7.6090 30.8020 7 37.0 7.5883 30.8576 6 37.9 7.5809 30.8824 7 38.9 7.5754 30.8990 7 39.9 7.5726 30.9080 6 41.0 7.5707 30.9129 9 41.5 7.5759 30.9134 1
