Seabed Sediment Laser Grain Size Data from the Leveque Shelf Survey

One hundred and eleven seabed sediment samples were collected during the May 2013 SOL5754/GA0340 marine survey of the Leveque Shelf, Browse Basin, Western Australia. The dataset includes results of grain size analysis measured by laser diffractometer. This survey was conducted by Geoscience Australia in collaboration with the Australian Institute of Marine Science to support an assessment of the CO2 storage potential of the Browse sedimentary basin.

Use Cases

• Assessing seabed sediment composition for CO2 storage site suitability based on grain size data.
• Identifying potential gas or fluid seepage features related to seabed structures based on sediment textural analysis.
• Mapping seabed habitats and biota potentially associated with seepage based on sediment sample locations.
• Evaluating the containment potential of CO2 in the basin's proposed storage unit based on shallow geological data.

Strengths

• 111 seabed sediment samples provide a substantial dataset for analysis.
• Grain size analysis was performed using a laser diffractometer, a precise measurement technique.
• Data was collected as part of a targeted government survey (National CO2 Infrastructure Plan) with a clear scientific aim.

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 Leveque Shelf survey area.
