Petrel Sub-basin Marine Survey: Seabed Video and Images for CO2 Storage Assessment

11 stations of underwater video footage and 12-megapixel still images were collected in the Petrel Sub-basin during May 2012. The survey was a collaboration between the Australian Institute of Marine Science and Geoscience Australia under the National Low Emission Coal Initiative. Its purpose was to acquire biophysical data in shallow seabed environments to investigate CO2 storage potential.

Use Cases

• Classify seabed habitats and organisms based on underwater video footage.
• Assess geological substrate suitability for CO2 storage based on seabed imagery.
• Analyze biophysical data correlations mentioned in the survey description.
• Benchmark computer vision models for underwater image analysis.

Strengths

• Imagery was collected from 11 distinct stations, providing multiple sampling points.
• Still images were captured at 12-megapixel resolution.
• Data collection was part of a structured government initiative (NLECI) with collaboration between AIMS and Geoscience Australia.

Limitations

• Imagery quality varies, and some still images were not suitable for analysis.
• No still images are available for stations 2, 4, and 7 due to system malfunction.
• Geo-location of transects is limited to ship navigation due to a failed acoustic tracking system.
