Deep-Sea Benthic Imagery from Southeast Australian Ecosystem Voyage

Imagery from a 30-day research voyage aboard the RV Investigator in late 2024, focused on the southeast Australian marine ecosystem. The dataset includes video and stereo stills of benthic habitats, collected using a Deep Towed Camera system. It was gathered by the Marine National Facility and published via the CSIRO Marlin Data Catalogue.

Use Cases

• Classify benthic substrate types (e.g., rock, sediment) from stereo still imagery for habitat mapping.
• Detect and count marine fauna in the video's oblique forward view for biodiversity assessments.
• Correlate observed benthic communities with accompanying navigational data (latitude, longitude, depth) to model species distribution.
• Train image segmentation models to distinguish biological features from geological structures in deep-sea environments.

Strengths

• Data collected during a dedicated 30-day research voyage with a standardized instrument (Deep Towed Camera).
• Includes multiple complementary data types: video, stereo stills, and navigational metadata.

Limitations

• Unknown sample size (number of images/video hours) makes it difficult to assess scope for model training.
• Limited temporal coverage to a single voyage in late 2024, restricting analysis of seasonal or inter-annual variation.
