48.9 million km² of seafloor surrounding Australia and its island territories has been systematically mapped for geomorphic features. The Australian Ocean Data Network produced this dataset, which identifies 21 feature types and 6702 individual features using a 250 m resolution bathymetry model. The data was last updated on 2026-05-05.
Use Cases
- Analyze the distribution of shelf, slope, and abyssal plain areas based on the mapped percentages provided in the description
- Study coral reef habitats based on the 4172 individual reef features, including those of the Great Barrier Reef
- Compare regional geomorphic assemblages based on the 10 defined geomorphic regions mentioned in the description
- Investigate the prevalence of marginal plateaus based on their coverage of 20% of the world's total area for this feature type
Strengths
- Systematic mapping of 48.9 million km² of seafloor
- Identification of 6702 individual geomorphic features across 21 types
- Use of a new, 250 m spatial resolution bathymetry model
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
