Seabed Sediment Grain Size Data from the Leveque Shelf, Western Australia

The Leveque Shelf in the Browse Basin, Western Australia, was surveyed in May 2013 by Geoscience Australia and the Australian Institute of Marine Science. The survey collected 111 seabed sediment samples to assess CO2 storage potential and seabed seepage features. This dataset contains the results of grain size analysis measured by laser diffractometer.

Use Cases

• Model seabed sediment properties for CO2 storage site assessment based on grain size and composition data.
• Analyze correlations between seabed geology and potential gas seepage features mentioned in the survey description.
• Map seabed habitats and biophysical communities associated with sediment characteristics.
• Assess the integrity of geological seal units for carbon containment based on shallow sediment data.

Strengths

• 111 seabed sediment samples provide a specific sample size for analysis.
• Data originates from a collaborative survey by Geoscience Australia and the Australian Institute of Marine Science.
• Analysis performed using a laser diffractometer suggests a standardized measurement method.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area.
