Seismic Unix (SU) is a public domain seismic processing software package written and maintained by the Center for Wave Phenomena at the Colorado School of Mines, in Golden Colorado. The current web site for SU is http://www.cwp.mines.edu/cwpcodes. SU is compatible with both UNIX and LINUX operating systems. The SU scripts provided on this disc and listed below were modified from scripts written by the USGS Seafloor Mapping Group in Woods Hole, MA and run on a Sun Solaris 7.0 workstation. These SU scripts and other necessary files and software are located in the Unix tar file called boom.tar within the SEISUNIX subfolder in the SOFTWARE folder at the top level of this DVD . These scripts are provided as examples only. They may need to be modified to run on another system. They also require the use of the shareware program ImageMagick.

The SU scripts provided here will allow the user to strip off navigation fixes from the SEG-Y headers collected in lattitude/longitude, along with a fix for every interval of 500 shots. The seismic data is then converted to SU format, filtered, gained and GIF formatted images are produced for each trackline. These images can then be displayed using a variety of shareware programs such as ImageMagick (UNIX or LINUX) or a web browser.
