GA0340: Seabed and Shallow Geology Survey of the Leveque Shelf, Western Australia

A 2013 marine survey of the Leveque Shelf, Browse Basin, Western Australia, conducted by Geoscience Australia and the Australian Institute of Marine Science. The survey collected seabed and shallow geological information to assess the CO2 storage potential of the basin. It aimed to identify evidence of past or current gas seepage and map associated seabed habitats and biota.

Use Cases

• Assessing geological containment potential for CO2 storage based on seabed and shallow geological information.
• Identifying seabed features related to subsurface faults and potential fluid seepage pathways.
• Mapping seabed habitats and biota that may be associated with seepage environments.
• Supporting regional integrity studies of seal formations like the Heywood Formation for carbon storage.

Strengths

• Survey conducted by authoritative national institutions Geoscience Australia and the Australian Institute of Marine Science.
• Data collection was part of the Australian Government's National CO2 Infrastructure Plan (NCIP), indicating a strategic purpose.
• Combines seabed mapping with deeper geological studies to address key containment questions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary data files are in PDF, DOCX, and HTML formats, which may require extraction for quantitative analysis.
