Underwater Video and Images from Carnarvon Shelf Survey

Underwater video footage and still images were collected from 122 stations during a marine survey on the Carnarvon Shelf. The survey was conducted by Geoscience Australia in collaboration with the Australian Institute of Marine Science between August and September 2008. Data was gathered to test physical parameters as surrogates for benthic biodiversity patterns.

Use Cases

• Classify benthic substrate types (e.g., sand, rock, coral) from video screen captures and still images.
• Analyze species abundance and distribution across 122 stations spanning water depths from 13 to 125 meters.
• Train computer vision models to detect marine organisms using labeled still images from the 'Image Library'.
• Correlate physical environmental parameters with biodiversity patterns observed in video transects from three areas (Mandu, Point Cloates, Gnarloo).

Strengths

• Data collected from 122 distinct sampling stations.
• Spatial coverage includes three defined areas: Mandu, Point Cloates, and Gnarloo.
• Depth range spans from 13 to 125 meters, covering a variety of benthic zones.

Limitations

• Video quality varies among transects and some still images were noted as unsuitable for analysis.
• Sample size and specific row counts for images or video clips are unknown.
• Data is from a single survey in 2008, limiting temporal analysis of changes.
