ORGANIZATION LAYOUT FOR MANAGING SHIPBOARD ADCP BY THE NODC/SAC


     A system for organizing the shipboard ADCP global data set on unix-based 
workstations for the data center level has been created.  The system utilizes
a directory tree for file storage and employs a simple C-language program for 
data base access.

     The unix/workstation environment provides the framework for the
organization.  Only the CODAS block files of the densely sampled data sets
will require external storage media.  The directory names will be of MS-DOS
convention; that is, the names will limited to 8 bytes.  This will allow
easy transfer to the PC environments.  The layout is as follows.


DIRECTORY TREE ORGANIZATION
===========================

 /sac                          <primary shipboard ADCP directory>
    /refs                      <subdirectory for code_cross_references,
                                PI name,address,data submission notes,
                                and other book keeping files>

    /utils                     <subdirectory for database management tools>
      /bin                     <executables>
      /cnt                     <control files for various programs>
      /src                     <source code>

    /bckup                     <backup tools and management files>

    /shipname.ctr              <subdirectory for all cruises from a unique ship;
                                for example, moanawve.usa>
      /year                    <subdirectory for given year; for example, 1994>
         /00001                     <subdirectory for cruise 00001,
           00001001.blk              only one cruise with this tag>
                  .         \
