         INTRODUCTION TO GEOPHYSICS OF NORTH AMERICA CD-ROM

  If you are a first time user of the Geophysics of North America
  CD-ROM, it is strongly recommended that you schedule 10 minutes to
  run the tutorial provided.  This will give you a good overview to
  the protocols used throughout the product.  

  Documentation exists at many levels:
	1. The User Manual provides details associated with the 
		data, the software and the hardware.
	2. Online help, accessible from most screens, can be called
		by pressing the "F1" key.  Instructions will appear on
		the monitor which will assist you in selecting the
		specific menu item or feature being implemented at the
		point help is requested.
	3. Details on specific data formats can be found within the
		CD-ROM in one of the many files annotated with a ".DOC"
		extension.  To learn how to view these documentation
		files, press "F1" for online help now.

  Many organizations supported the compilation of the data used in the
  CD-ROM,  including government agencies, academia and private industry.
  Several of the data sets were originally developed for maps and other
  projects.  Some of these were part of the Geological Society of America's
  centennial celebration -- "Decade of North American Geology" --
  and earlier efforts supported by the Society of Exploration Geophysicists
  and other organizations.  Chairpersons or principal data compilers for 
  these projects were in organizations such as:
		
  U. S. Geological Survey       Geological Survey of Canada
  Purdue University             Southern Methodist University
  Defense Mapping Agency        U. S. Naval Oceanographic Office
		
		National Oceanic & Atmospheric Administration
		National Aeronautics & Space Administration
		U. S. Fleet Numerical Oceanographic Center

  For details on data compilers, see the chapter "History of Data
  Compilation" in the User Manual.
