Australian Ocean Bottom Seismograph Fleet Data

A fleet of Australian ocean bottom seismographs records passive-source seismic data, including earthquakes and ambient noise, and active-source data from airgun arrays. These instruments provide three-component recording capability for analyzing both P-waves and S-waves. Data collected during commercial seismic surveys in Australian waters enables imaging of crust and upper mantle velocity distribution.

Use Cases

• Analyze seismic survey noise and whale calls recorded by ocean bottom seismographs for environmental monitoring
• Image the velocity distribution of the whole crust and upper mantle from reflected and refracted phases generated by airgun arrays
• Study passive-source seismic data, including earthquakes and ambient noise, using three-component recording capability

Strengths

• Seismographs have a broadband frequency range, with similar instruments available at only five or six institutions globally
• Multi-purpose devices record passive-source seismic data, active-source data, and monitor seismic survey noise and whale calls
• Three-component recording capability allows analysis of S-waves in addition to conventionally used P-waves

Limitations

• Specific data volume, file formats, and column structure are unknown
• Data is presented in an HTML abstract, which may not contain raw or structured data files
• Temporal and spatial coverage details for the collected data are not specified
