AGSO Formats: Marine Seismic and Navigation Digital Data

AGSO digital seismic data adheres to the standard tape formats described by Barry et al. (1975). The dataset includes trace header mnemonics defined by AGSO and CogniSeis DISCO software, with variations for unstacked field data and optional entries like SHOT and SPN. It serves as a format description for marine seismic and navigation data, detailing conventions for shot point annotation and historical numbering changes.

Use Cases

• [Interpret vintage seismic data] based on [historical pseudo shot point numbers (SPN) used prior to 1993]
• [Relate processed data to original field records] based on [trace header fields like FFID, SHOT, and time values]
• [Apply static corrections for field acquisition systems] based on [expanded TRACED codes for unstacked data]
• [Produce shot point maps] based on [the SHOT annotation convention at the mid-point]
• [Merge seismic lines for processing] based on [re-sequenced SHOT numbers for continuous numbering]

Strengths

• [Adheres to a recognized geophysical standard] citing [Barry et al. 1975 Recommended Standards for Digital Tape Formats]
• [Documents specific institutional conventions] citing [AGSO-defined trace header mnemonics and variations]
• [Clarifies historical data interpretation] citing [the transition from SPN to SHOT numbering in 1993]

Limitations

• [Dataset size, row count, and specific column names are unknown across all sources]
• [License and author information is not provided]
• [The description is a format specification, not a dataset of actual seismic traces]
