Seafloor Imagery from the Totten Seafloor, East Antarctica

Seafloor imagery collected aboard the RVIB Nathaniel B Palmer during the NBP14-02 expedition from January to March 2014. The Ocean Imaging Systems DSC 10000 digital still camera captured images of seafloor habitats across an area greater than 3000 km². Imagery is hosted by the National Computing Infrastructure (NCI) data catalogue.

Use Cases

• Classify seafloor habitats based on visual features in the imagery.
• Analyze benthic biodiversity patterns across the surveyed area.
• Validate and calibrate remote sensing models of Antarctic seafloor composition.
• Study the impact of environmental factors on Antarctic marine ecosystems.

Strengths

• Imagery covers a surveyed area greater than 3000 km².
• Camera specifications are detailed: 10.2 megapixel Nikon D-80 with a 20 mm lens.
• Each image captures approximately 4.8 m² of seafloor, triggered at 2.5 m above the bottom.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific expedition.
