Leveque Shelf Seabed Sediment Laser Grainsize Data for CO2 Storage Assessment

111 seabed sediment samples were collected in May 2013 during the SOL5754/GA0340 marine survey of the Leveque Shelf, Browse Basin. Geoscience Australia, in collaboration with the Australian Institute of Marine Science, conducted this survey to assess the CO2 storage potential of the region. The dataset includes grain size analysis results measured by laser diffractometer.

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 geological faults mentioned in the survey description.
• Mapping seabed habitats and biota potentially associated with seepage events.
• Evaluating the integrity of seal units for carbon containment based on sedimentological data.

Strengths

• 111 physical seabed sediment samples provide a concrete data foundation.
• Data originates from a targeted government survey (SOL5754/GA0340) under the National CO2 Infrastructure Plan.
• Analysis performed using a specific, standardized method (laser diffractometer).

Limitations

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