Geoscience Australia Data presents a fleet of Australian ocean bottom seismographs (OBSs) with broadband frequency range, a capability available at only five or six institutions globally. The dataset includes passive-source seismic data from earthquakes and ambient noise, active-source data from airgun arrays, and concurrent monitoring of seismic survey noise and whale calls. The abstract was presented at the 2017 Australian Petroleum Production & Exploration Association (APPEA) Conference & Exhibition.
Use Cases
- Image crust and upper mantle velocity distribution based on reflected and refracted phases from airgun arrays.
- Analyze S-waves in addition to conventional P-waves based on the three-component recording capability of the OBSs.
- Monitor seismic survey noise for environmental impact assessments as described in the dataset's purpose.
- Detect and analyze whale calls during commercial seismic surveys based on the multi-purpose monitoring capability.
Strengths
- Instruments have a broadband frequency range, a feature available at only five or six institutions globally.
- Devices are multi-purpose, capable of recording passive-source, active-source, and environmental noise data simultaneously.
- Data proves the capability to image the whole crust and upper mantle from industry-standard airgun arrays.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
