    DESCENT RATE FILTER OF 0.4 M/S.  1M AVERAGE.  SAL INVERSE CHK. AYP LEE

    In situ checks of the temperature and conductivity sensor were obtained by
    putting a Niskin water sampling bottle with reversing thermometers on the
    probe cable, one metre above the probe. Temperature calibration checks were
    acceptable given the +-0.02 degree C accuracy of the reversing thermometers.
    A stable salinity offset of 0.04 ppt (sample standard deviation of 0.01 ppt
    based on over 50 calibrations samples) was noted in these calibrations over
    the 32 month duration of the survey program. In the subsequent processing
    of the data, salinity is corrected by subtracting this offset.
    See reference Pacific Marine Science Report 80-5(1) and 80-5(2).
