SEA-MES Voyage 2: Benthic Habitat Imagery from RV Investigator, May 2024

May 2024 imagery and data collected during the RV Investigator voyage IN2024_V03, titled 'Untangling the causes of change over 25 years in the southeast marine ecosystem'. The dataset includes video, stereo stills, and navigational data from the Marine National Facility's Deep Towed camera, gathered between Hobart and Sydney.

Use Cases

• Analyze changes in benthic habitat composition over time based on the voyage's 25-year change study focus.
• Develop stereo image processing algorithms for underwater scenes based on the stereo stills data.
• Correlate visual habitat observations with oceanographic conditions based on the combined imagery and oceanographic data.
• Map seafloor features and habitats along the voyage track based on the navigational data paired with imagery.

Strengths

• Data collected during a dedicated month-long research voyage (May 01-31, 2024) with a clear scientific objective.
• Includes multiple data modalities: video, stereo stills, and navigational data from a specialized Deep Towed camera instrument.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
