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 12.7349 20.8199 5 1.9 12.5936 21.2768 7 2.9 11.0673 23.5526 6 4.0 9.6616 26.3529 6 5.0 9.1108 27.6239 5 6.0 8.5743 28.7653 6 6.9 8.4270 29.1366 6 7.9 8.2451 29.5159 6 8.9 8.0832 29.8557 6 9.9 8.0315 29.9704 6 10.9 8.0000 30.0368 6 11.9 7.9531 30.1336 6 12.9 7.8491 30.3425 6 13.9 7.7567 30.5358 6 14.9 7.7389 30.5806 6 15.9 7.7351 30.5914 6 16.9 7.7230 30.6176 6 18.0 7.6961 30.6785 7 19.0 7.6825 30.7122 6 20.0 7.6739 30.7301 6 21.0 7.6670 30.7467 6 22.0 7.6592 30.7670 6 22.9 7.6559 30.7778 6 23.9 7.6503 30.7915 6 25.0 7.6441 30.8060 6 25.9 7.6374 30.8200 5 26.9 7.6308 30.8358 6 27.9 7.6260 30.8491 6 28.9 7.6234 30.8570 6 29.9 7.6172 30.8731 6 30.9 7.6095 30.8937 6 31.9 7.6033 30.9112 6 32.9 7.5983 30.9254 6 34.0 7.5906 30.9456 7 35.0 7.5869 30.9565 6 35.9 7.5849 30.9632 6 36.9 7.5790 30.9833 7 38.0 7.5610 31.0403 6 38.9 7.5386 31.1101 6 40.0 7.5298 31.1425 8 41.0 7.5278 31.1506 8
