Seabed Sediment Grain Size Data from the Leveque Shelf Marine Survey

The Leveque Shelf, a sub-basin of the Browse Basin on the Northwest Shelf of Western Australia, was surveyed in May 2013 to assess its CO2 storage potential. Geoscience Australia, collaborating with 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 those samples.

Use Cases

• Modeling seabed sediment distribution based on laser-measured grain size data.
• Assessing geological seal integrity for CO2 storage based on sediment composition.
• Identifying potential seabed fluid seepage features mentioned in the survey description.
• Mapping seabed habitats and biota associated with specific sediment textures.

Strengths

• Data originates from a targeted marine survey (SOL5754/GA0340) conducted by Geoscience Australia.
• Includes analysis of 111 distinct seabed sediment samples.
• Grain size was measured using a laser diffractometer, a standardized method.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
