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 10.7917 10.6341 5 1.9 10.8498 11.5007 7 2.9 10.9882 15.2426 7 4.0 10.2531 23.0190 7 5.0 9.5727 27.1350 6 5.9 9.0100 28.9754 6 6.9 8.8491 29.3669 7 8.0 8.6688 29.6284 7 9.0 8.3083 30.1206 5 9.9 8.1101 30.3995 6 10.9 8.0699 30.4591 6 11.9 8.0265 30.5214 6 12.9 8.0077 30.5518 6 13.9 8.0012 30.5634 6 14.9 7.9788 30.6029 6 15.9 7.9482 30.6519 6 17.0 7.8746 30.7204 7 18.0 7.7804 30.7990 6 19.0 7.7554 30.8299 7 20.0 7.7286 30.8617 6 21.0 7.7218 30.8688 7 22.0 7.7084 30.8866 6 22.9 7.7024 30.8998 6 23.9 7.7015 30.9123 7 24.9 7.7072 30.9220 6 25.9 7.7064 30.9257 6 26.9 7.6846 30.9437 6 27.9 7.6681 30.9594 7 28.9 7.6716 30.9667 6 30.0 7.6726 30.9760 7 31.0 7.6745 30.9892 6 31.9 7.6736 31.0002 7 32.9 7.6715 31.0059 8 33.9 7.6749 31.0151 7 34.9 7.6711 31.0366 7 36.0 7.6679 31.0524 7 37.0 7.6706 31.0590 6 37.9 7.6536 31.0684 7 38.9 7.6206 31.0834 6 39.9 7.6201 31.0812 7 40.9 7.6167 31.0827 8
