    COOKBOOK CTD data was collected using a SeaBird CTD 9-11 Plus at
the maximum sampling rate of 24 samples per second (24 Hz). They were
screened for errors and processed to 1-dbar averages. Each file
contains one full profile (e.g., cb1s2up.ctd contains the up-cast CTD
data from COOKBOOK-1, station 2).

    CTD data are written to files using formats specified by the WOCE
Hydrographic Programme Office. These formats are based on NODC formats,
and are detailed in the WHP Office Report WHPO 90-1, available from
Steve Diggs, WHPO Data Manager, Scripps Institution of Oceanography,
9500 Gilman Drive, La Jolla, CA 92093-0214.

    The files are self-explanatory; one column is written for each
measured parameter.  Missing data are filled with -9. A three-line
heading labels each column.  Variables having asterisks in their
heading have a quality flag associated with them. These quality flags
are concatenated as a quality word which is listed as the last variable
in each row.  The values each digit can assume and their meanings
follows:


Quality Indicators:

	Flag  Meaning
	 1    not quality controled
	 2    good data
	 3    suspect (i.e.  questionable) data
	 4    bad data
	 5    missing data
	 9    variable not measured during this cast
