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 12.6672 15.9925 5 1.9 12.5277 16.8568 8 3.0 11.8792 19.2361 6 4.0 11.2811 21.3329 6 5.0 10.7666 22.8999 5 5.9 10.4216 24.0718 6 7.0 10.0655 25.3241 6 7.9 9.3704 26.9200 5 8.9 8.7265 28.5321 6 10.0 8.6026 28.9015 5 10.9 8.5043 29.1415 5 11.9 8.3872 29.4528 5 12.9 8.1043 30.0427 5 14.0 8.0036 30.2940 5 15.0 7.9110 30.4772 5 16.0 7.8639 30.5905 5 16.9 7.8224 30.7012 7 18.0 7.7886 30.7874 6 18.9 7.7743 30.8394 5 20.0 7.7562 30.8724 6 21.0 7.7430 30.8905 5 22.0 7.7350 30.9134 5 22.9 7.7301 30.9305 5 24.0 7.7341 30.9380 6 25.0 7.7491 30.9500 5 26.0 7.7564 30.9580 5 26.9 7.7572 30.9595 5 28.0 7.7564 30.9618 6 29.0 7.7658 30.9889 5 29.9 7.7742 31.0220 5 31.0 7.7771 31.0546 6 31.9 7.7752 31.0819 5 33.0 7.7747 31.1017 6 34.0 7.7757 31.1115 6 35.0 7.7833 31.1215 6 36.0 7.7883 31.1281 5 36.9 7.7912 31.1329 6 37.9 7.7953 31.1444 5 38.9 7.8012 31.1566 6 39.9 7.8037 31.1636 6 41.0 7.8063 31.1715 10
