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 13.0025 19.4207 5 1.9 12.5772 19.6815 8 2.9 12.1414 20.6045 6 3.9 10.7565 23.7719 7 4.9 9.5380 26.9050 6 5.9 8.6546 29.0765 6 6.9 8.3329 29.8657 5 7.9 8.2739 30.0279 6 8.9 8.2321 30.1236 5 10.0 8.2202 30.1616 6 11.0 8.1821 30.2462 5 11.9 8.1327 30.3558 5 13.0 8.1024 30.4456 6 14.0 8.0706 30.5449 5 14.9 8.0503 30.6166 6 16.0 8.0341 30.6558 6 16.9 8.0101 30.6987 5 17.9 7.9983 30.7267 6 19.0 7.9969 30.7438 6 20.0 7.9931 30.7680 6 21.0 7.9870 30.7845 5 21.9 7.9832 30.7956 5 22.9 7.9671 30.8332 6 24.0 7.9537 30.8665 5 24.9 7.9479 30.8781 5 26.0 7.9508 30.8831 6 26.9 7.9482 30.9006 5 27.9 7.9301 30.9626 6 29.0 7.9130 31.0191 6 30.0 7.8842 31.0621 6 31.0 7.8773 31.0734 5 31.9 7.8707 31.0842 6 33.0 7.8654 31.0958 6 34.0 7.8582 31.1099 6 35.0 7.8522 31.1159 6 35.9 7.8408 31.1277 5 36.9 7.8361 31.1377 6 37.9 7.8351 31.1446 6 38.9 7.8298 31.1585 6 39.9 7.8292 31.1717 6 40.9 7.8331 31.1803 7
