Leveque Shelf Seabed Geology and Habitat Survey for CO2 Storage Assessment

Geoscience Australia's 2013 marine survey SOL5754/GA0340 collected seabed and shallow geological data to assess CO2 storage potential. The survey specifically targeted evidence of past or current gas seepage and mapped associated seabed habitats on the Leveque Shelf, Browse Basin. Data was gathered in collaboration with the Australian Institute of Marine Science aboard the RV Solander.

Use Cases

• Correlate seabed seepage features with underlying fault structures from geophysical interpretations.
• Model CO2 containment potential by analyzing the relationship between shallow seepage and deeper seal unit integrity.
• Map seabed biota and habitat distributions to identify communities associated with fluid seepage sites.
• Assess regional seal integrity of the Heywood Formation using evidence of seabed fluid escape.

Strengths

• Interpretative report integrates seabed geology, seepage evidence, and habitat mapping from a dedicated 2013 marine survey.
• Research addresses specific CO2 storage assessment questions for a basin identified by a national taskforce.

Limitations

• Primary data formats are interpretative reports (PDF, DOCX), not raw tabular or sensor data.
• Sample data and specific column schemas for measurements are unavailable.
• Survey is a single temporal snapshot from May 2013.
