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

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

Use Cases

• Assessing seabed sediment composition for CO2 storage site suitability based on grain size data.
• Investigating potential gas or fluid seepage features related to geological faults mentioned in the description.
• Mapping seabed habitats and biota potentially associated with seepage events.
• Evaluating the regional integrity of seal formations for carbon containment based on sediment properties.

Strengths

• Data originates from a targeted marine survey (SOL5754/GA0340) conducted by Geoscience Australia and the Australian Institute of Marine Science.
• Includes analysis results from 111 distinct seabed sediment samples.
• Grain size analysis was performed using a laser diffractometer, a standard method.

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 2026-06-23.
