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 12.3321 11.5404 5 2.0 12.3058 12.0678 7 3.0 11.2986 17.3815 6 3.9 9.5898 25.2083 6 4.9 9.2926 26.8039 6 5.9 9.2587 27.0068 6 6.9 9.1279 27.4065 6 7.9 8.8432 28.2380 7 8.9 8.3377 29.3657 6 9.9 8.0996 29.8641 6 10.9 7.9850 30.1005 6 11.9 7.8216 30.3962 7 12.9 7.7456 30.5466 6 13.9 7.7186 30.6135 6 14.9 7.6809 30.7101 6 15.9 7.6632 30.7706 6 16.9 7.6660 30.7857 7 18.0 7.6671 30.7950 6 19.0 7.6649 30.7993 6 20.0 7.6614 30.8032 8 21.0 7.6551 30.8068 7 22.0 7.6503 30.8090 6 23.0 7.6438 30.8128 6 24.0 7.6164 30.8305 6 24.9 7.6164 30.8291 7 26.0 7.6111 30.8315 7 27.0 7.6097 30.8321 6 28.0 7.6098 30.8316 7 28.9 7.6038 30.8343 6 29.9 7.5942 30.8387 7 30.9 7.5933 30.8381 7 31.9 7.5782 30.8436 7 32.9 7.5305 30.8674 7 33.8 7.5244 30.8688 7
