Browse Basin Underwater Video and Images for CO2 Storage Assessment

49 stations of underwater video and still images were collected by Geoscience Australia in May 2013 on the Leveque Shelf, a sub-basin of the Browse Basin off Western Australia. The survey aimed to identify evidence of gas or fluid seepage and map seabed habitats to assess the area's potential for long-term CO2 storage. Data includes AVI video files, still images, and USBL navigation files providing location, time, and depth for each transect.

Use Cases

• Identify seabed gas or fluid seepage features based on underwater video footage.
• Map seabed habitats and associated biota mentioned in the survey description.
• Analyze the relationship between seabed features and underlying geological structures like faults.
• Assess site suitability for CO2 storage based on observed seabed integrity and seepage evidence.

Strengths

• Data collected from 49 specific stations provides spatial coverage of the target area.
• Includes multiple data modalities: video files, still images, and continuous USBL navigation data.
• Survey was conducted under a defined government plan (National CO2 Infrastructure Plan) 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.
