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 11.8986 15.1758 5 2.0 11.8235 15.2148 8 2.9 11.7323 15.2948 8 4.0 11.6870 15.4251 7 4.9 11.6527 15.6422 6 5.9 11.5953 16.2352 7 7.0 11.1202 19.5114 6 7.9 9.7380 25.5026 6 8.9 8.7214 28.9754 6 9.9 8.4705 29.7612 6 10.9 8.3716 30.0041 6 11.9 8.3056 30.1596 6 12.9 8.2393 30.3055 6 14.0 8.1970 30.4096 7 15.0 8.1076 30.6018 6 15.9 8.0262 30.7789 6 16.9 7.9954 30.8441 7 18.0 7.9815 30.8719 7 19.0 7.9702 30.8930 7 20.0 7.9472 30.9337 6 20.9 7.9405 30.9458 7 22.0 7.9345 30.9557 7 22.9 7.9268 30.9686 7 23.9 7.9282 30.9666 7 24.9 7.9232 30.9740 6 25.9 7.9200 30.9803 7 27.0 7.9018 31.0092 7 28.0 7.8889 31.0316 7 29.0 7.8847 31.0390 6 30.0 7.8745 31.0556 8 31.0 7.8613 31.0784 9 32.0 7.8411 31.1090 7 33.0 7.8392 31.1137 7 33.9 7.8390 31.1138 7 34.9 7.8345 31.1210 7 35.9 7.8282 31.1314 7 36.9 7.8264 31.1360 7 37.9 7.8031 31.1749 7 38.9 7.7478 31.2598 7 39.9 7.6959 31.3348 8 40.7 7.6837 31.3548 4
