The Leveque Shelf, a sub-basin of the Browse Basin on Western Australia's Northwest Shelf, was surveyed in May 2013. Geoscience Australia and the Australian Institute of Marine Science collected 111 seabed sediment samples to assess CO2 storage potential and map habitats. This dataset contains the laser-measured grain size analysis results from those samples.
Use Cases
- Assessing seabed sediment composition for CO2 storage site suitability based on grain size data
- Mapping seabed habitats and biophysical features potentially associated with gas seepage
- Correlating sediment texture with geological structures like faults mentioned in the survey aims
- Evaluating the integrity of seal units like the Heyward Formation for containment studies
Strengths
- 111 physical seabed sediment samples provide a concrete dataset
- Analysis performed by laser diffractometer suggests precise grain size measurement
- Survey conducted under the National CO2 Infrastructure Plan with a clear research aim
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 metadata update was 2026-05-05
