Vlaming Sub-Basin Seabed Survey for CO2 Storage Assessment, 2012

Geoscience Australia conducted a seabed characterisation survey in March and April 2012 to support the assessment of CO2 storage potential in the Vlaming Sub-basin, Western Australia. The survey collected 89 seabed grab samples from 43 stations, 653 km² of multibeam and backscatter data, 6.65 km² of side-scan sonar imagery, and chirper shallow sub-bottom profile data. The work aimed to understand links between deep geological features and the seabed to evaluate seal integrity for potential CO2 storage.

Use Cases

• Modeling potential CO2 reservoir seal integrity based on seabed geomorphology and structural lineaments.
• Mapping seabed habitats and geological features like rhodolith beds and fault-like structures from multibeam and side-scan sonar data.
• Analyzing the spatial correlation between seabed samples and underlying geology for site characterization.

Strengths

• Survey collected data from 43 stations, including 89 seabed grab samples.
• Acquired 653 km² of multibeam and backscatter data alongside 6.65 km² of side-scan sonar imagery.
• Data targets two specific areas (Area 1 and Area 2) with distinct geomorphic features described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The precise relationship between seabed features and subsurface geology is noted as uncertain.
