25,500 km² of seabed on the northern Lord Howe Rise plateau in the Tasman Sea is mapped using high resolution multibeam bathymetry. The Australian Ocean Data Network provides this dataset, which interprets geomorphic units like ridges, valleys, volcanic peaks, and polygonal furrows. The data was last updated on 2026-05-05.
Use Cases
- Analyze seabed geomorphology based on mapped units like ridges, valleys, and plateaus.
- Study geological controls on seabed features based on the distribution of geomorphic units.
- Investigate sedimentation processes based on features like moats, holes, and polygonal furrows.
- Map volcanic intrusions and acoustic basement highs based on clusters of peaks in water depths of 1400-1600 m.
Strengths
- High resolution multibeam bathymetry provides detailed seabed mapping.
- The mapped area covers approximately 25,500 km².
- The dataset extends a previous hierarchy of geomorphic provinces and features for the Australian margin.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated date is 2026-05-05.
