Facts Regarding Open File Report  99-449


   The information contained on this CD-ROM may be accessed as ASCII text files or from HyperText Markup Language (HTML), a standard language utilized by the World Wide Web (WWW) project.  Development of the CD-ROM documentation and user interface in HTML allows a user to access the information by using a variety of WWW information browsers (i.e. Netscape, Microsoft Internet Explorer) to facilitate browsing and locating information and data. The disk should be viewable by all WWW browsers but may not properly format on some older WWW browsers.

Each CDROM contains a complete set of the HTML pages, image files and navigation data, but only SEG-Y data for 1/3 of the seismic lines. This was done due to large size of the SEG-y files and the limited amount of space on each CDROM.
