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 11.7847 24.4561 5 1.9 11.5936 24.6963 8 2.9 10.7202 26.0367 7 4.0 8.4286 29.3929 6 4.9 8.1505 29.9790 6 5.9 8.1414 30.0003 6 6.9 8.1280 30.0184 6 7.9 8.1170 30.0392 6 8.9 8.0759 30.1120 6 9.9 8.0695 30.1285 5 10.9 8.0599 30.1462 6 11.9 8.0572 30.1593 6 12.9 7.9679 30.3545 7 13.9 7.7561 30.8086 7 14.9 7.6549 31.1040 6 15.9 7.6398 31.1739 6 16.9 7.6360 31.1892 6 17.9 7.6356 31.1905 6 18.9 7.6354 31.1909 6 20.0 7.6362 31.1923 6 20.9 7.6380 31.1957 6 21.9 7.6372 31.1945 7 22.9 7.6370 31.1934 6 24.0 7.6378 31.1964 7 25.0 7.6376 31.1974 6 25.9 7.6364 31.1980 6 26.9 7.6376 31.2032 7 27.9 7.6382 31.2064 6 28.9 7.6365 31.2175 7 30.0 7.6354 31.2321 8 30.9 7.6348 31.2328 7 32.0 7.6308 31.2393 7 32.9 7.6323 31.2393 7 33.9 7.6339 31.2359 7 35.0 7.6334 31.2356 7 36.0 7.6344 31.2324 6 36.9 7.6334 31.2324 7 37.9 7.6343 31.2349 7 39.0 7.6344 31.2340 8 40.0 7.6368 31.2342 8
