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 11.9056 21.7312 5 1.9 11.2816 23.1127 9 2.9 10.7666 24.3159 7 4.0 10.7820 24.4675 7 4.9 10.7360 24.7675 6 5.9 10.2819 25.9328 6 6.9 9.5212 27.4581 6 7.9 9.1316 28.2649 6 8.9 8.9862 28.5456 5 9.9 8.7750 28.9709 6 10.9 8.5601 29.4212 6 12.0 8.4610 29.6448 6 12.9 8.4408 29.6934 5 13.9 8.4487 29.6881 6 14.9 8.4235 29.7649 5 15.9 8.3244 30.0038 6 16.9 8.2271 30.2253 6 18.0 8.1844 30.3434 6 19.0 8.0998 30.5596 6 20.0 8.0443 30.7184 6 21.0 8.0331 30.7535 6 22.0 8.0126 30.8055 6 23.0 8.0000 30.8379 7 23.9 7.9968 30.8461 6 24.9 7.9881 30.8609 6 26.0 7.9771 30.8837 6 27.0 7.9533 30.9320 6 27.9 7.9365 30.9690 5 28.9 7.9364 30.9731 6 29.9 7.9378 30.9720 6 31.0 7.9387 30.9793 6 32.0 7.9382 30.9914 6 33.0 7.9318 31.0049 5 33.9 7.9229 31.0198 6 35.0 7.9211 31.0397 6 36.0 7.9215 31.0634 6 36.9 7.9205 31.0785 6 38.0 7.9153 31.0945 6 39.0 7.9032 31.1269 5 40.0 7.8973 31.1492 6 40.8 7.8885 31.1891 6
