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 9.6524 6.8305 4 1.9 9.7165 7.4916 8 2.9 9.8466 12.2260 7 3.9 9.9312 22.7641 6 5.0 9.7821 26.0456 7 6.0 9.5181 27.3836 6 7.0 8.6786 29.3409 7 8.0 8.3678 30.0532 8 9.0 8.2715 30.1944 7 10.0 8.2156 30.2762 7 11.0 8.1584 30.3525 7 12.0 8.0138 30.5138 6 13.0 7.8226 30.7342 7 14.0 7.7965 30.7724 6 14.9 7.7823 30.7947 6 15.9 7.7764 30.8057 6 16.9 7.7697 30.8241 7 18.0 7.7646 30.8390 8 19.0 7.7607 30.8546 8 20.0 7.7604 30.8694 8 20.9 7.7563 30.8773 7 21.9 7.7552 30.8890 7 23.0 7.7526 30.8969 6 24.0 7.7464 30.9079 6 25.0 7.7423 30.9208 7 26.0 7.7413 30.9260 6 27.0 7.7385 30.9334 6 27.9 7.7337 30.9435 5 28.9 7.7303 30.9555 6 29.9 7.7250 30.9706 6 31.0 7.7228 30.9831 6 32.0 7.7227 30.9916 7 33.0 7.7165 31.0065 6 33.9 7.6979 31.0341 8 34.9 7.6941 31.0389 7 35.9 7.6849 31.0508 7 36.9 7.6684 31.0707 7 38.0 7.6671 31.0746 7 39.0 7.6704 31.0769 6 40.0 7.6686 31.0807 7 40.8 7.6514 31.0941 6
