SeaCat salinity is prone to error due to a mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. Such errors are likely to be larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05 units in areas of high gradients. *CALIBRATION $TABLE: CALCULATED CHANNELS !Name Units Fmla Pad Coefficients !--------------------- --------------- ---- ------ ------------ Temperature:Primary 'deg C (ITS90)' 10 -99 () (0.57E-02 1) Salinity:T0:C0 PSS-78 10 -99 () (-0.129E-01 1) $END !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure: :T0:C0 er_o !
