Underwater Video and Images from the Browse Basin for CO2 Storage Assessment

Geoscience Australia collected underwater video and still images from 49 stations on the Leveque Shelf in May 2013. This marine 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. The data includes AVI video files, still images, and USBL navigation files providing location, time, and depth for each transect.

Use Cases

• Detecting past or present gas seepage features based on seabed video and image analysis.
• Mapping seabed habitats and biota potentially associated with geological faults or seepage.
• Assessing the integrity of potential CO2 storage seals by correlating seabed features with deeper geological structures.
• Training computer vision models for automated classification of underwater geological and biological features.

Strengths

• Data originates from a targeted government survey (GA340/SOL5754) conducted by Geoscience Australia.
• Includes multiple data modalities: video from 49 stations, still images, and continuous navigational (USBL) data.
• Survey was designed to address specific questions about CO2 containment and seal integrity in a proposed storage basin.

Limitations

• Video quality is noted to vary between the 49 collection sites.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
