Geoscience Australia Data provides a high-resolution geomorphic map of a submerged plateau on the northern Lord Howe Rise. The dataset covers approximately 25,500 km² and details features like ridges, valleys, volcanic peaks, and polygonal furrows formed in carbonate ooze. It was last updated on 2026-04-20.
Use Cases
- Analyzing seabed geomorphology based on mapped units like ridges, valleys, and plateaus.
- Studying volcanic feature distribution based on described clusters of peaks on acoustic basement highs.
- Investigating sedimentary processes based on the described network of polygonal furrows attributed to dewatering.
- Mapping geological structure controls based on the distribution of geomorphic units described in the study.
Strengths
- Covers a large area of approximately 25,500 square kilometers.
- Provides high-resolution mapping of geomorphic features not previously detailed on the Australian margin.
- Based on multibeam bathymetry data, which suggests detailed seafloor measurements.
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 as the last update date is in the future (2026-04-20).
