Seafloor Imagery from the Totten Seafloor, East Antarctica

Over 3000 km2 of seafloor imagery was collected aboard the RVIB Nathaniel B Palmer during the NBP14-02 expedition from 29 January to 16 March 2014. The Australian Ocean Data Network provides this data, captured using a 'yoyo' camera system with a 10.2-megapixel digital still camera and strobe, imaging approximately 4.8 m2 per shot. Still images have been analyzed for seafloor habitats and are hosted by the National Computing Infrastructure.

Use Cases

• Classifying seafloor habitats based on analyzed still imagery.
• Training object detection models for marine fauna using high-resolution seafloor photos.
• Conducting geospatial analysis of benthic ecosystems across a 3000 km2 survey area.
• Benchmarking image segmentation algorithms on underwater imagery with known camera settings.

Strengths

• Imagery covers a survey area exceeding 3000 km2.
• High-resolution 10.2-megapixel still images with documented camera settings (F-8, Focus 1.9 m, ASA-400).
• Each image captures a consistent, quantified area of approximately 4.8 m2 of seafloor.

Limitations

• Row count and total number of images are unknown, which may limit suitability assessment.
• Column-level documentation for any associated metadata is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to the single expedition in early 2014.
