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 14.7002 13.6520 5 2.0 14.7052 13.6478 8 2.9 14.6827 13.8282 7 3.9 12.2125 18.6612 8 5.0 9.8545 25.8936 7 6.0 9.2458 27.9457 7 7.0 9.0620 28.5541 7 7.9 8.6323 29.3599 6 8.9 8.3278 29.7937 7 10.0 8.1963 29.9466 7 10.9 8.1217 30.0447 7 11.9 8.0364 30.1528 8 13.0 7.9383 30.2812 7 13.9 7.8857 30.3481 8 14.9 7.8685 30.3735 7 15.9 7.8512 30.4025 8 17.0 7.8382 30.4285 7 18.0 7.8134 30.4653 7 19.0 7.7992 30.4833 8 20.0 7.7604 30.5353 7 20.9 7.7420 30.5670 7 21.9 7.7416 30.5711 8 23.0 7.7309 30.5904 8 24.0 7.7134 30.6157 8 25.0 7.7105 30.6230 8 26.0 7.7111 30.6266 8 27.0 7.7069 30.6348 9 27.9 7.6953 30.6539 7 28.9 7.6738 30.6922 7 29.9 7.6349 30.7560 7 31.0 7.6102 30.7958 7 32.0 7.5953 30.8189 7 33.0 7.5863 30.8346 7 34.0 7.5783 30.8488 7 35.0 7.5703 30.8649 6 36.0 7.5583 30.8879 7 37.0 7.5481 30.9089 6 37.9 7.5396 30.9249 6 39.0 7.5288 30.9530 7 39.9 7.5225 30.9751 7
