Seafloor Imagery from the Totten Region in East Antarctica

January to March 2014 imagery from the RVIB Nathaniel B Palmer expedition NBP14-02 across a >3000 km² area. The dataset contains downward-facing digital still and video camera images of the seafloor, analyzed for habitat types. It is hosted by the Australian Ocean Data Network via the National Computing Infrastructure.

Use Cases

• Classify seafloor habitats from 10.2-megapixel still images using image segmentation techniques.
• Analyze spatial distribution of benthic features across the >3000 km² survey area using georeferenced imagery.
• Train object detection models on seafloor imagery to identify biological or geological structures.
• Correlate imagery with oceanographic data from the NBP14-02 expedition for ecological studies.

Strengths

• High-resolution 10.2-megapixel still images captured with standardized camera settings (F-8, Focus 1.9 m, ASA-400).
• Systematic coverage of a >3000 km² area in the Totten region, providing broad spatial context.
• Imagery triggered at a consistent 2.5 m above seafloor, capturing approximately 4.8 m² per frame.

Limitations

• Sample size and total row count (number of images) are unknown.
• Data is from a single expedition in 2014, limiting temporal analysis and recency.
• Specific license terms and detailed metadata for individual images are unknown.
