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 12.5966 19.3690 5 1.9 12.4139 20.1110 7 3.0 11.5458 23.6713 6 4.0 10.5138 26.9645 5 5.0 10.1321 27.7499 5 6.0 9.9611 27.9786 5 7.0 9.6077 28.5126 5 7.9 9.2533 29.1192 5 9.0 9.1354 29.3621 6 10.0 9.0795 29.4704 5 10.9 8.8961 29.7434 5 11.9 8.7964 29.8995 5 12.9 8.7372 30.0010 6 14.0 8.7011 30.0556 5 14.9 8.6749 30.1018 6 16.0 8.6460 30.1529 6 17.0 8.6357 30.1739 5 17.9 8.5858 30.2511 5 19.0 8.5177 30.3538 6 20.0 8.4758 30.4165 5 20.9 8.4400 30.4741 5 21.9 8.3539 30.6026 5 22.9 8.2725 30.7299 6 24.0 8.2546 30.7628 5 24.9 8.2232 30.8128 5 26.0 8.1923 30.8726 6 27.0 8.1450 30.9575 6 27.9 8.0625 31.0972 7
