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 12.3843 19.6095 5 2.0 12.0798 20.3585 8 3.0 11.7016 21.5344 6 3.9 10.2277 25.1989 7 5.0 9.6902 26.8261 6 5.9 9.3939 27.5874 6 6.9 9.2224 28.0527 6 8.0 8.6344 29.2110 6 9.0 8.2720 29.8945 6 10.0 8.2079 30.0212 6 11.0 8.1374 30.1515 6 12.0 8.0293 30.3608 7 13.0 7.9486 30.5453 6 14.0 7.9005 30.6749 7 15.0 7.8867 30.7237 7 15.9 7.8837 30.7295 6 16.9 7.8763 30.7481 6 17.9 7.8677 30.7747 6 18.9 7.8503 30.8338 6 19.9 7.8379 30.8843 6 20.9 7.8410 30.8934 6 22.0 7.8440 30.9034 6 23.0 7.8452 30.9118 5 23.9 7.8476 30.9209 6 25.0 7.8477 30.9347 6 26.0 7.8379 30.9474 6 27.0 7.8372 30.9546 6 28.0 7.8476 30.9594 6 29.0 7.8559 30.9636 5 29.9 7.8586 30.9653 5 30.9 7.8506 30.9725 6 31.9 7.8496 30.9711 5 32.9 7.8208 30.9746 6 33.9 7.7890 30.9767 6 35.0 7.7831 30.9758 6 35.9 7.7671 30.9869 6 36.9 7.7568 31.0096 7 38.0 7.7504 31.0358 6 39.0 7.7526 31.0493 6 40.0 7.7738 31.0632 8 40.6 7.7861 31.0725 3
