How to Download SEG-Y Data

The sub-bottom 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 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 at 1-888-ASK-USGS or infoservices@usgs.gov.

The SEG-Y formatted trace files have a .sgy extension. A detailed description of the data format can be found at http://www.seg.org/publications/tech-stand.

NOTE: These files may be extremely large. The SEG-Y files for 09CCT01 range in size from 55 to 883 MB.
