Tasmanian Shelf and Bass Strait Superficial Sediment Samples

The Australian Ocean Data Network provides a dataset of 365 surface and near-surface seabed samples from the Tasmanian continental shelf and parts of Bass Strait. The data supports an assessment of regional lithofacies variations, including sediment composition, heavy mineral suites, and geochemical analyses. The dataset was last updated on 2026-04-16.

Use Cases

• Map regional lithofacies variations based on seabed sample composition.
• Analyze sediment provenance and offshore transport based on heavy mineral suites.
• Identify areas of modern versus relict sedimentation based on sediment type descriptions.
• Assess potential mineral resources based on geochemical analyses for elements like tin and phosphorus.

Strengths

• Based on 365 surface and near-surface seabed samples.
• Includes geochemical analysis results, such as a maximum recorded value of 10 ppm Sn.
• Covers a specific geographic area: the Tasmanian shelf and parts of Bass Strait.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description notes a low density of sample stations in parts of the shelf.
