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 12.3986 22.1333 5 1.9 12.3724 22.2610 9 2.9 12.0166 23.4258 8 3.9 10.6437 25.9851 8 4.9 9.4829 27.6935 7 5.9 9.1641 28.2300 8 7.0 9.0568 28.4275 8 7.9 8.9983 28.5309 7 8.9 8.7932 28.8400 8 10.0 8.6742 29.0641 7 10.9 8.4763 29.4118 8 11.9 8.3872 29.6027 7 12.9 8.3642 29.6689 8 14.0 8.3406 29.7232 8 15.0 8.2724 29.8512 8 15.9 8.1514 30.0932 8 16.9 8.0566 30.2911 8 17.9 7.9716 30.4638 8 18.9 7.9142 30.5701 8 20.0 7.8562 30.6785 10 20.9 7.8258 30.7365 8 21.9 7.7811 30.8274 7 22.9 7.7237 30.9382 8 23.9 7.6930 31.0002 7 24.9 7.6731 31.0445 8 25.9 7.6632 31.0629 7 27.0 7.6576 31.0758 6 27.9 7.6465 31.0992 7 28.9 7.6354 31.1244 6 29.9 7.6275 31.1422 7 31.0 7.6257 31.1481 6 32.0 7.6215 31.1579 6 33.0 7.6184 31.1662 6 33.9 7.6163 31.1708 6 34.9 7.6141 31.1756 6 35.9 7.6116 31.1818 6 37.0 7.6103 31.1871 7 38.0 7.6066 31.1983 6 39.0 7.5982 31.2186 7 39.8 7.5944 31.2311 6
