A fleet of Australian ocean bottom seismographs (OBSs) with broadband frequency range, similar instruments are available at only five or six institutions globally. These multi-purpose devices record passive-source seismic data (earthquakes, ambient noise) and active-source data from airgun arrays, while also monitoring seismic survey noise and whale calls. Data collected during commercial seismic surveys in Australian waters demonstrates the capability to image the velocity distribution of the whole crust and upper mantle.
Use Cases
- Analyze crust and upper mantle velocity distribution based on reflected and refracted seismic phases.
- Monitor seismic survey noise and whale calls for environmental impact assessment.
- Study earthquake and ambient noise patterns using passive-source seismic recordings.
- Compare P-wave and S-wave data from three-component OBS recordings.
Strengths
- Broadband frequency range comparable to instruments at only five or six institutions globally.
- Multi-purpose capability to record passive-source, active-source, and environmental monitoring data simultaneously.
- Three-component recording 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.
- Freshness should be verified; last metadata update was 2026-05-05.
