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 10.1855 27.2089 5 2.0 10.2187 27.1697 8 2.9 10.1664 27.3021 6 3.9 9.4427 28.5202 6 5.0 8.4948 30.1918 7 6.0 8.3618 30.5193 6 7.0 8.2988 30.6449 7 7.9 8.2787 30.6831 7 8.9 8.2426 30.7382 6 10.0 8.1516 30.8788 6 11.0 8.1150 30.9474 6 11.9 8.1020 30.9769 5 12.9 8.0834 31.0136 7 13.9 8.0666 31.0452 6 14.9 8.0444 31.0850 7 15.9 8.0258 31.1196 6 17.0 8.0229 31.1267 8 17.5 8.0249 31.1273 2
