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 12.6568 9.2137 5 1.9 12.5746 9.4820 9 2.9 12.3213 10.3449 8 4.0 11.9136 12.3714 7 4.9 9.6074 22.1060 7 5.9 8.7204 27.2409 7 6.9 8.4728 28.3133 7 7.9 8.3091 28.8746 8 9.0 7.9230 29.8920 7 9.9 7.8266 30.2192 7 10.9 7.7778 30.3525 8 12.0 7.7644 30.3941 7 12.9 7.7616 30.4030 8 14.0 7.7358 30.4597 8 15.0 7.7303 30.4737 8 15.9 7.7194 30.4997 8 16.9 7.6903 30.5704 9 18.0 7.6825 30.5933 7 19.0 7.6760 30.6091 8 20.0 7.6709 30.6227 7 21.0 7.6671 30.6323 8 22.0 7.6642 30.6406 8 23.0 7.6536 30.6679 8 24.0 7.6463 30.6880 8 24.9 7.6305 30.7323 7 25.9 7.6129 30.7829 8 27.0 7.6073 30.8004 8 28.0 7.6030 30.8134 8 29.0 7.5921 30.8449 8 30.0 7.5751 30.8972 8 30.9 7.5675 30.9223 7 31.9 7.5651 30.9288 7 33.0 7.5620 30.9370 8 34.0 7.5590 30.9454 7 35.0 7.5556 30.9554 8 35.8 7.5548 30.9605 7
