Deep-Sea Benthic Imagery from RV Investigator Southeast Ecosystem Survey

Imagery and oceanographic data collected during the RV Investigator voyage IN2024_V05, focused on the southeast marine ecosystem. The dataset includes video and stereo stills of benthic habitats, gathered over a voyage from November 13 to December 12, 2024. Data collection was performed by the Australian Ocean Data Network using a Deep Towed Camera system.

Use Cases

• Classify benthic substrate types and organisms from video frames and stereo stills.
• Analyze changes in deep-sea ecosystems over time by comparing imagery with navigational data for spatial context.
• Train object detection models to identify marine species in oblique forward-view imagery.
• Correlate visual habitat data with concurrent oceanographic measurements for environmental impact studies.

Strengths

• Includes multiple data modalities: video, stereo stills, and navigational data.
• Data collected over a focused 30-day voyage with a specific scientific mission.

Limitations

• Unknown sample size and image resolution limits quantitative analysis.
• Limited temporal coverage to a single month in late 2024.
• Geographic scope is restricted to the survey track of the RV Investigator voyage.
