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 2.0 8.7668 28.8356 8 3.0 8.7450 28.9009 6 4.0 8.7066 29.0666 7 5.0 8.4862 29.8342 6 5.9 8.3477 30.3874 6 6.9 8.3440 30.4283 6 7.9 8.3191 30.5551 6 8.9 8.2927 30.6926 6 9.9 8.2881 30.7212 6 11.0 8.2842 30.7390 7 11.9 8.2833 30.7467 8
