    CRUISE             :  MEDS 015-87-020
    LOCATION           :  Beaufort Sea
    DURATION           :  21-28 March, 1987
    PLATFORM           :  DHC-6 Twin Otter, CF-IOK
    POSITIONING        :  GNS500A VLF/OMEGA
    REFERENCE POSITION :  Tuktoyaktuk, 69 26.3 N, 133 01.8 W

                        MODEL  SERIAL NUMBER
    CTD                 8706   42306
    PRESSURE (1500DB)   207D45 51357
    CONDUCTIVITY RATIO  87410  41671
    TEMPERATURE         87401  49497

    Calibration data for all profiles of the `cruise' have been combined in the
    file:  BEAUFORT_IMP87_CTD%_CALIBRATIONS.INFO
    Details are not included in the appropriate section of this header.

    Shifts in the CR were encountered during this profile.  These may be associated
    with a `sticky' suppression step in conductivity,

       6011 : The probe was malfunctioning seriously during the 2 profiles at this
    station (6011, 6011C).  6011C data should be disregarded, since the temperature
    measured by the CTD is in gross disagreement with that measured by the
    thermistors in the probe.  6011 has the `sticky' bit problem, and in addition
    shows a dramatic drop in in the conductivity ratio at about 35m depth.  The
    profile has been truncated at this level, although the temperature measurements
    appear to be good to the seafloor at 52m depth.

       6011 : No salinity data are available for this (troublesome) profile.
    However, the location is close to that of profile 6025, acquired four days
    later.  Salinities calibrated using the value of the cell constant obtained for
    the preceding profile appeared too low (FTD's near -0.060 celsius!).  The
    salinity in the surface mixed layer which would yield a FTD typical of other
    profiles (+0.003 celsius) is about 30.39.  The mixed layer salinity for 6025 is
    30.47.  In the absence of any other information, it seemed reasonable to select
    the cell constant (1.033389) as that required to yield this surface layer
    salinity (30.39).
