Description of program wodASC.f
-------------------------------------------------------------

wodASC.f is a program designed to read the depth dependent
variables from a file in World Ocean Database (WOD) native
ASCII format. The program prompts the user to input the file
to be read. The user then selects which depth dependent variables
they would like to write to an output file. The program then reads
the input WOD native format file and writes the chosen  variable
data into a 2 space separated column format or a 2 comma separated
colun format  as such: 2(f12.4) or 2(f12.4,','). The user has the
choice of comma separated or straight tabular (space separated) form.

The first column is the depth and the second column is the 
variable value. Before each new profile, there is a line
containing the latitude, longitude, year, month and day of 
the profile measurement. This line begins with a % which is the comment
line denoter in Matlab. Therefore, this line will not be
read into Matlab when loading the file, but it does allow
the user to physically scan the data first and manipulate it
by individual profile if the user so chooses. If the depth level
contains a missing value for the variable, then the variable
and it's associated depth are not written to the output file.

To create an executable, compile in standard FORTRAN
(e.g.)  g77 -o <executable_file> wodASC.f


Reading into Matlab:
-------------------------------------------------------------

An example:  wodASC.f has been run and the user has created
a file entitled chl_all.5000 chlorophyll data have been read. 

In Matlab type:

load chl_all.5000
depth = chl_all(:,1)
chl   = chl_all(:,2)


The user is now ready to create a scatter diagram or 
manipulate the data in Matlab.
