Underwater Video and Images from Browse Basin Seabed Survey

Underwater video and still images were collected from 49 stations during a marine survey of the Leveque Shelf in May 2013. The survey was conducted by Geoscience Australia to assess seabed geology and habitats for CO2 storage potential. It includes video transects, real-time characterizations, and navigational data from the Northwest Shelf of Western Australia.

Use Cases

• Identify seabed features like faults or seepage sites using video transects and associated USBL navigation data (location, time, depth).
• Characterize benthic habitats and biota by analyzing still images from specific station and deployment folders (e.g., 12CAM02).
• Correlate real-time onboard video classifications (AIMS-TowedVid system) from CSV files with specific video files and geological structures.
• Map the spatial distribution of survey findings by linking station data from video filenames and USBL files to the Browse Basin geography.

Strengths

• Data collected from 49 distinct stations providing multiple observation points.
• Includes multiple data modalities: video files (AVI), still images, real-time classification CSVs, and navigational USBL text files.
• Survey conducted with a clear, documented aim to support CO2 storage assessment under a national government plan.

Limitations

• Video quality is explicitly noted to vary between the 49 stations.
• Sample data and specific row/column counts for derived data (e.g., CSV classifications) are unavailable.
• The dataset's primary temporal coverage is a single survey in May 2013, limiting longitudinal analysis.
