Seabed Environments and Shallow Geology for CO2 Storage Assessment, Western Australia

Geoscience Australia's 2012 survey collected 653 km² of multibeam data and 89 seabed samples to assess CO2 storage potential. The data reveals coralline algal beds and fault-like structures in two areas of the Rottnest Shelf. Precise links between seabed geomorphology and deep geological features for seal integrity require further investigation.

Use Cases

• Modeling potential CO2 reservoir seal integrity based on seabed and shallow geology correlations.
• Mapping seabed geomorphology and fault structures from multibeam and side-scan sonar data.
• Analyzing sediment composition and connectivity for geological storage site characterization.
• Studying coralline red algal (rhodolith) bed distribution and its relation to underlying geology.

Strengths

• Includes 653 km² of multibeam and backscatter data for detailed seabed mapping.
• Contains 89 physical seabed grab samples from 43 stations for ground-truthing.
• Covers two distinct survey areas with different geomorphic features (faults, algal beds).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The precise relationship between seabed features and deep geology is noted as uncertain.
• Data formats are HTML and PDF, which may require extraction for computational analysis.
