Australian Ocean Bottom Seismograph Fleet Data for Crustal Imaging

A fleet of Australian ocean bottom seismographs (OBSs) records passive-source and active-source seismic data. The instruments have a broadband frequency range and three-component recording capability, allowing analysis of both P-waves and S-waves. Data collected during commercial seismic surveys in Australian waters can image the velocity distribution of the crust and upper mantle.

Use Cases

• Image crust and upper mantle velocity distribution based on reflected and refracted seismic phases.
• Monitor seismic survey noise and whale calls based on the multi-purpose environmental monitoring capability.
• Analyze S-wave propagation based on the three-component recording capability of the instruments.

Strengths

• Instruments have a broadband frequency range.
• Similar instruments are available at only five or six institutions globally.
• Three-component recording capability allows analysis of both P-waves and S-waves.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
