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 12.5026 6.5458 5 1.9 12.5991 6.6570 7 2.9 12.7531 6.8937 7 4.0 13.0972 8.4035 6 5.0 10.9439 18.8057 6 6.0 9.3558 26.3270 6 6.9 9.0120 27.7694 6 7.9 8.8980 28.1240 6 9.0 8.6390 28.7068 7 10.0 8.5634 28.9170 6 11.0 8.4001 29.2451 6 11.9 8.3548 29.3647 6 12.9 8.2152 29.6399 7 14.0 8.0215 30.0099 6 14.9 8.0001 30.0674 8 16.0 7.9859 30.0890 6 17.0 7.9521 30.1516 6 17.9 7.8822 30.2736 6 19.0 7.8620 30.3192 7 20.0 7.8288 30.3777 7 20.7 7.8097 30.4165 5
