Petrel Sub-basin Marine Survey (GA-0335 / SOL5463) (NLECI Program) - Ecology / Seabed unde

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 on shallow seabed environments to investigate CO2 storage potential.

Use Cases

• Assess seabed habitat composition based on underwater video footage.
• Analyze biophysical features for CO2 storage site investigation as mentioned in the survey purpose.
• Study the quality and variability of underwater imagery from a towed-camera system.
• Link visual data to ship navigation due to the failure of the acoustic geo-location system.

Strengths

• Imagery includes 12 megapixel resolution still photographs.
• Data was collected from 11 distinct stations across two targeted areas.
• Survey was conducted by a recognized research vessel (RV Solander) and institutions (AIMS, GA).

Limitations

• No still images are available for stations 2, 4, and 7 due to system malfunction.
• Geo-location of video transects is linked only to ship navigation due to USBL system failure.
• The quality of imagery varies among transects, with some stills unsuitable for analysis.
