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 10.5052 20.5827 5 1.9 10.0689 22.2447 6 2.9 9.6533 23.7971 6 4.0 9.2533 25.3329 6 5.0 8.8645 26.8878 5 5.9 8.2317 29.0364 6 6.9 7.9275 30.1292 6 7.9 7.8696 30.3264 6 9.0 7.7660 30.5463 5 10.0 7.7502 30.5824 5 11.0 7.7457 30.5921 6 12.0 7.7462 30.5976 5 12.9 7.7413 30.6108 6 13.9 7.7395 30.6154 5 15.0 7.7427 30.6097 6 16.0 7.7421 30.6096 5 17.0 7.7331 30.6219 6 18.0 7.7174 30.6415 5 19.0 7.7056 30.6568 6 19.9 7.6950 30.6740 5 21.0 7.6868 30.6924 6 22.0 7.6864 30.6977 5 23.0 7.6865 30.7023 6 23.9 7.6830 30.7264 5 25.0 7.6657 30.8018 6 25.9 7.6230 30.9234 5 27.0 7.6120 30.9474 6 28.0 7.5953 30.9688 5 29.0 7.5897 30.9893 6 30.0 7.5932 31.0111 5 31.0 7.5935 31.0141 6 32.0 7.5935 31.0208 5 33.0 7.5900 31.0347 6 34.0 7.5855 31.0485 6 34.9 7.5858 31.0485 5 35.9 7.5849 31.0492 6 36.9 7.5839 31.0520 6 37.9 7.5812 31.0579 5 38.9 7.5764 31.0645 6 40.0 7.5743 31.0694 6 40.8 7.5784 31.0659 7
