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 Seismic Unix is http://www.cwp.mines.edu/cwpcodes/index.html. SU is compatible with both Unix and Linux operating systems. The SU scripts provided on this disc were modified from scripts written by the USGS Seafloor Mapping Group in Woods Hole, MA, and run on a Red Hat Linux 7.3 workstation. These SU scripts are in the Linux tar files boom.tar and chirp.tar, which can be found in the SU subfolder of the SOFTWARE folder located 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.

DUMPSEGY.EXE is a DOS seismic data utility that allows the user to examine all the components of the SEG-Y data files (Zihlman, 1992): the EBCDIC and binary headers, the individual data trace headers, and the hexadecimal SEG-Y samples composing a data trace, or their actual floating point values. The DUMPSEGY.TXT file is the original open-file report that gives detailed instructions on how to use DUMPSEGY.EXE. The DSGYNEWS.TXT file describes the upgrades to the original program. All of these files are located in the USGS subfolder of the SOFTWARE folder located at the top level of this DVD. Please refer to DUMPSEGY.TXT and DSGYNEWS.TXT for further infomation and instruction.
