Note: The Web version of this archive does not contain the SEG-Y Trace files. These files are very large and would require extremely long download times. To obtain the complete DVD archive, contact USGS Information Services at 1-888-ASK-USGS.

The seismic data files are binary encoded and cannot be viewed directly. The best way to download these files is to open the SEGY folder, select the SEG-Y files you wish to download, and drag and drop these files onto your hard drive or use the File > Copy command.

The SEG-Y formatted trace files have a .TRA extension. Additional recording parameters for each trace file can also be found in the .PAR file associated with each .TRA file; however, the .PAR files included here are only needed to process or display the data with Delph Seismic software. A detailed description of the data format can be found on the SEG-Y Format page.

Disc 1 contains SEG-Y files for lines 05c01_a through 05c13_b, and disc 2 contains SEG-Y files for lines 05c14 through 05c21.

WARNING: These files may be extremely large. The SEG-Y files for 05SCC01 range in size from 48 to 506 MB.
