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 12.1039 8.6231 5 1.9 11.0080 15.0750 9 2.9 10.0184 20.3502 7 3.9 8.8819 26.0488 7 5.0 8.5265 27.9019 7 6.0 8.4086 28.3754 7 6.9 8.3238 28.6909 8 7.9 8.1476 29.2476 7 8.9 7.8973 29.9855 7 9.9 7.8558 30.1388 7 10.9 7.8476 30.1593 8 12.0 7.8412 30.1725 7 12.9 7.8336 30.1935 6 14.0 7.8284 30.2075 7 15.0 7.8285 30.2068 7 16.0 7.8271 30.2102 7 17.0 7.8236 30.2194 6 18.0 7.8142 30.2451 7 19.0 7.7965 30.2946 6 19.9 7.7762 30.3525 7 20.9 7.7641 30.3974 6 21.9 7.7410 30.4584 7 23.0 7.7226 30.5022 7 24.0 7.7155 30.5154 7 25.0 7.7133 30.5222 6 25.9 7.7123 30.5250 7 26.9 7.7126 30.5243 6 27.9 7.7100 30.5301 7 29.0 7.7027 30.5485 7 30.0 7.7004 30.5536 6 30.9 7.6950 30.5656 7 32.0 7.6889 30.5801 7 33.0 7.6831 30.5973 7 34.0 7.6807 30.6045 7 35.0 7.6810 30.6033 8 36.0 7.6805 30.6033 8 37.0 7.6778 30.6079 7 38.0 7.6778 30.6080 7 39.0 7.6809 30.6019 7 40.0 7.6849 30.5934 8 40.5 7.6837 30.5983 2
