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 15.4762 15.4836 5 1.9 13.6573 18.4695 8 2.9 10.9239 23.6025 7 3.9 9.6708 26.3550 6 4.9 9.2979 27.2366 6 6.0 9.1325 27.6319 7 7.0 9.0238 27.9577 6 8.0 8.2769 29.4164 6 8.9 7.9983 30.0672 6 9.9 7.9736 30.1343 6 10.9 7.9280 30.2269 7 12.0 7.8987 30.2824 5 12.9 7.8709 30.3317 6 13.9 7.8591 30.3538 6 14.9 7.8493 30.3769 6 15.9 7.8007 30.4772 6 17.0 7.7190 30.6382 7 18.0 7.7017 30.6799 6 19.0 7.6852 30.7192 6 19.9 7.6649 30.7670 6 20.9 7.6456 30.8120 7 22.0 7.6314 30.8449 6 22.9 7.6213 30.8674 7 24.0 7.6147 30.8839 6 24.9 7.5953 30.9255 6 26.0 7.5797 30.9688 7 27.0 7.5653 31.0081 6 27.9 7.5652 31.0113 6 28.9 7.5610 31.0218 7 30.0 7.5571 31.0324 6 30.9 7.5460 31.0628 7 31.9 7.5337 31.0971 6 33.0 7.5361 31.0916 7 34.0 7.5387 31.0830 6 34.9 7.5397 31.0770 6 35.9 7.5492 31.0549 7 37.0 7.5419 31.0719 6 37.9 7.5305 31.1032 7 39.0 7.5213 31.1287 8 39.9 7.5223 31.1287 7
