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 13.0163 16.7982 5 1.9 12.1067 19.1569 7 3.0 10.2278 24.3717 6 3.9 9.9273 25.5742 5 4.9 9.8076 25.8616 7 6.0 9.7339 26.0675 6 6.9 9.6481 26.2764 6 7.9 9.5989 26.4156 6 8.9 9.4524 26.7922 6 9.9 8.9382 28.0244 7 10.9 8.5350 29.0230 6 12.0 8.3830 29.3820 7 12.9 8.2866 29.5794 6 13.9 8.2070 29.7532 7 14.9 8.0710 30.0156 7 15.9 7.9533 30.2636 6 16.9 7.7291 30.6916 7 18.0 7.6849 30.7885 6 19.0 7.6694 30.8280 7 20.0 7.6500 30.8708 6 21.0 7.6419 30.8886 7 21.9 7.6393 30.8932 6 22.9 7.6291 30.9122 7 24.0 7.6054 30.9639 6 24.9 7.5931 30.9974 6 25.9 7.5906 31.0049 6 27.0 7.5906 31.0058 7 28.0 7.5875 31.0180 6 28.9 7.5763 31.0504 7 30.0 7.5730 31.0571 7 31.0 7.5723 31.0592 6 31.9 7.5715 31.0609 6 32.9 7.5705 31.0633 7 34.0 7.5693 31.0667 6 34.9 7.5662 31.0782 7 36.0 7.5633 31.1073 6 36.9 7.5642 31.1213 6 37.9 7.5570 31.1441 7 38.9 7.5514 31.1679 6 39.9 7.5491 31.1807 7 41.0 7.5467 31.1944 9 41.5 7.5519 31.1959 1
