High-resolution multibeam bathymetry data maps seabed geomorphology for a ~25,500 km² area of the northern Lord Howe Rise plateau in the Tasman Sea. The dataset, published via the Australian Ocean Data Network, interprets features like ridges, valleys, volcanic peaks, and an extensive network of polygonal furrows formed in carbonate ooze. The mapping extends a previous hierarchy of geomorphic provinces and features used for the Australian margin.
Use Cases
- Analyzing the relationship between seabed geomorphology and underlying geological structures based on the described distribution of units.
- Studying the formation processes of polygonal furrows attributed to dewatering in carbonate ooze.
- Mapping volcanic features and their clustering on acoustic basement highs as described in the study.
- Comparing sedimentation rate variations in relation to bathymetric highs using localized elements like moats and holes.
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.
- Interprets a diverse set of features including ridges, valleys, volcanic peaks, scarps, aprons, and polygonal furrows.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Data is provided in HTML format, which may not be a standard data file for direct analysis.
