Digitized Analog Boomer Seismic Data from Mississippi Sound, September 1989

An archive of high-resolution seismic reflection profiles collected by the U.S. Geological Survey in Mississippi Sound and Bay St. Louis. The data were originally recorded on analog paper rolls and have been digitally scanned and processed into SEG-Y formatted files. The survey was conducted from the R/V Ecoli between September 13 and 19, 1989.

Use Cases

• Analyzing shallow subsurface geology based on high-resolution seismic reflection profiles.
• Studying coastal sediment layers and geological history based on scanned seismic imagery.
• Developing or testing seismic data processing algorithms based on converted SEG-Y files.
• Mapping historical survey tracks and core locations based on provided navigation and logbook data.

Strengths

• Data originates from the authoritative U.S. Geological Survey Coastal and Marine Geology Program.
• Includes multiple data types: scanned images, SEG-Y files, navigation data, cruise tracklines, logbooks, and maps.
• Analog records were processed to fix distortions and crop blank spaces, indicating quality control.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
