Browse Basin Underwater Video and Images for Seabed and CO2 Storage Assessment

The Leveque Shelf of the Browse Basin, Western Australia, was surveyed in May 2013 to assess its CO2 storage potential. Geoscience Australia collected underwater video from 49 stations, still images, and navigational data to study seabed seepage, habitats, and geological structures. This data supports research on the integrity of proposed geological units for long-term carbon dioxide containment.

Use Cases

• Detecting evidence of past or current gas seepage based on seabed video and image analysis.
• Mapping seabed habitats and biota potentially associated with geological seepage features.
• Correlating seabed observations with subsurface faults and structures mentioned in the survey aims.
• Assessing the seabed integrity and features relevant to the containment potential of a CO2 storage unit.

Strengths

• Data collected from 49 distinct stations, providing multiple observation points.
• Includes multiple data modalities: video files, still images, and USBL navigational text files.
• Survey was conducted under a national government plan (NCIP) with a clear scientific aim.

Limitations

• Video quality varies between sites, which may affect analysis consistency.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
