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 10.3597 25.8660 5 1.9 10.3991 25.8935 7 3.0 9.5454 27.3473 6 4.0 8.6406 28.9767 6 5.0 8.4254 29.4300 6 5.9 8.3365 29.6272 5 6.9 8.2303 29.8017 6 7.9 8.1553 29.9480 5 8.9 8.1319 30.0058 6 9.9 8.0717 30.1242 5 10.9 8.0038 30.2589 6 12.0 7.9904 30.2950 6 13.0 7.9643 30.3464 6 14.0 7.9530 30.3680 5 14.9 7.9478 30.3763 6 15.9 7.9391 30.3945 6 16.9 7.8916 30.4790 6 17.9 7.8776 30.5185 6 18.9 7.8437 30.5956 5 19.9 7.8209 30.6474 6 20.9 7.7977 30.6957 7 22.0 7.7721 30.7506 6 22.9 7.7593 30.7831 6 23.9 7.7448 30.8196 6 24.9 7.7350 30.8471 6 26.0 7.7249 30.8731 6 27.0 7.7159 30.9028 6 28.0 7.7054 30.9370 6 29.0 7.6795 31.0071 6 30.0 7.6753 31.0270 6 30.9 7.6728 31.0331 7 31.9 7.6736 31.0308 6 32.9 7.6689 31.0418 6 34.0 7.6692 31.0423 8 34.8 7.6712 31.0454 5
