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 1.1 10.9035 10.0259 4 1.9 10.9744 12.1798 7 2.9 10.8110 16.9098 6 4.0 9.9542 24.3183 6 5.0 9.2144 28.1084 6 6.0 8.6813 29.4891 6 7.0 8.3621 30.0534 5 8.0 8.2342 30.2412 6 8.9 8.1727 30.3177 5 9.9 8.1158 30.3831 6 11.0 8.0507 30.4542 6 12.0 8.0070 30.4986 5 13.0 7.9428 30.5643 5 13.9 7.8926 30.6131 6 14.9 7.8583 30.6434 6 16.0 7.7994 30.6952 6 16.9 7.7609 30.7299 5 17.9 7.7178 30.7653 6 18.9 7.6972 30.7806 5 19.9 7.6800 30.7943 6 21.0 7.6609 30.8158 6 22.0 7.6496 30.8287 6 23.0 7.6352 30.8453 6 23.9 7.6191 30.8676 5 24.9 7.6146 30.8835 6 25.9 7.5893 30.9174 6 26.9 7.5657 30.9412 6 27.9 7.5605 30.9509 6 28.9 7.5578 30.9586 6 29.9 7.5545 30.9662 7 31.0 7.5525 30.9710 6 31.9 7.5374 30.9938 7 33.0 7.5251 31.0148 7 34.0 7.5134 31.0397 7 35.0 7.5043 31.0581 8 35.7 7.4948 31.0752 4
