GAB Deepwater Marine Program: Benthic Video Transects of Seamounts and Seeps

The Great Australian Bight contains video and still imagery of seabed fauna from towed camera transects. Data was collected during two Marine National Facility voyages, IN2015_C01 and IN2017_C01, targeting volcanic seamounts, canyons, and seep zones at depths between 1000 and 5000 meters. The Australian Ocean Data Network archives this imagery, with annotations stored in the BHIMAGE database.

Use Cases

• Characterizing species composition and abundance based on annotated video and still imagery.
• Mapping the distribution of benthic fauna associated with specific deep-sea habitats like seamounts and seeps.
• Studying habitat-biota relationships in deepwater environments within the Great Australian Bight.

Strengths

• Data originates from two dedicated research voyages, IN2015_C01 and IN2017_C01.
• Targets specific, ecologically distinct habitats: 6 potential seep sites and 5 volcanic seamounts.
• Covers a significant depth gradient from approximately 1000 to 5000 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific survey voyages.
