*COMMENTS
    PROCESSED CTD DATA FROM THE HP 2100 ACQUISITION SYSTEM, CONVERTED FROM BINARY
    TO ASCII. HYDRO CORRECTIONS HAVE BEEN APPLIED TO THE DATA.

    Collection method:
      Salinity-Temperature-pressure data were obtained with a Guildline CTD.
      Output from the probe consisted of analogue voltages of temperature,
      conductivity and pressure. The probe output was input into a 2100-series
      HP computer, digitized at a rate of 10 samples per second and stored on
      a 9-track magnetic tape.
