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 10.5261 21.8986 5 2.0 10.6815 22.9739 8 3.0 11.2696 25.7098 7 4.0 10.5043 27.3866 6 5.0 9.6357 28.7451 6 6.0 9.2365 29.2550 5 6.9 8.9012 29.5351 7 7.9 8.8393 29.7255 6 8.9 8.7324 29.8310 7 9.9 8.6814 29.9041 6 10.9 8.5370 30.0250 7 12.0 8.4274 30.1492 7 12.9 8.3512 30.2602 6 13.9 8.2113 30.3979 7 14.9 8.0026 30.6041 7 15.9 7.9620 30.6494 7 17.0 7.9417 30.6698 8 17.9 7.9182 30.6972 7 18.9 7.8881 30.7328 8 20.0 7.8487 30.7758 7 20.9 7.8387 30.7872 7 22.0 7.8334 30.7933 7 22.9 7.8156 30.8139 7 23.9 7.7666 30.8700 7 25.0 7.7369 30.9043 7 26.0 7.7329 30.9074 6 27.0 7.7272 30.9147 7 28.0 7.6699 30.9805 7 28.9 7.6131 31.0530 7 29.9 7.6086 31.0609 7 31.0 7.5999 31.0694 7 32.0 7.5694 31.1060 7 33.0 7.5630 31.1200 7 33.9 7.5515 31.1400 7 34.9 7.5471 31.1513 7 35.9 7.5381 31.1677 7 36.9 7.5291 31.1865 7 37.9 7.5197 31.2097 8 38.9 7.5125 31.2311 7 40.0 7.5100 31.2421 7 41.0 7.5075 31.2565 9
