Tasman Fracture Marine Reserve AUV Survey: Scored Benthic Images from 2014/15

A scored subset of approximately 18,400 underwater images collected by an Autonomous Underwater Vehicle (AUV) in the Tasman Fracture Commonwealth Marine Reserve during a 2014/15 pilot study. The images were scored for the proportion cover of visible macrobiota using 25 random points per image. The data was contributed by the Australian Ocean Data Network as part of the National Marine Biodiversity Hub's monitoring program.

Use Cases

• Training image classification models for benthic organisms based on the scored proportion cover data.
• Analyzing the distribution and cover of epibenthic biota within a marine reserve as described in the survey aim.
• Mapping seafloor habitats using georeferenced AUV imagery and associated biological classifications.
• Benchmarking automated annotation tools against the manually scored point data from the images.

Strengths

• Approximately 18,400 images provide a substantial visual record of the seafloor.
• Each image was scored using a standardized method of 25 random points for biological cover.
• Taxon are classified using a morphospecies scheme that can be mapped to the established CATAMI standard.

Limitations

• Row count for the scored data subset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the underlying survey was conducted in 2014/15.
