Australian waters data collected by a fleet of multi-purpose ocean bottom seismographs (OBSs). The instruments have a broadband frequency range and are available at only five or six institutions globally. Data was presented at the 2017 Australian Petroleum Production & Exploration Association (APPEA) Conference & Exhibition.
Use Cases
- Imaging crust and upper mantle velocity distribution based on reflected and refracted seismic phases.
- Monitoring seismic survey noise and whale calls for environmental impact assessment.
- Analyzing S-waves in addition to conventional P-waves using three-component recording capability.
- Obtaining regional-scale geological information as a by-product of commercial seismic surveys.
Strengths
- Instruments have a broadband frequency range, which is rare globally.
- OBSs are multi-purpose, capable of recording both passive-source and active-source seismic data.
- Three-component recording allows for analysis of both P-waves and S-waves.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
