Leveque Shelf Seabed Sediment Grain Size Data from 2013 Marine Survey

Geoscience Australia and the Australian Institute of Marine Science collected 111 seabed sediment samples in May 2013 during the SOL5754/GA0340 survey of the Leveque Shelf, Browse Basin. This dataset provides laser-measured grain size analysis results to support an assessment of the area's CO2 storage potential. The research aimed to identify evidence of past or current gas seepage and map seabed habitats.

Use Cases

• Modeling sediment transport and deposition based on grain size distribution.
• Assessing seabed integrity for potential CO2 storage containment based on sediment composition.
• Correlating seabed habitats and biota with geological features mentioned in the survey description.
• Analyzing the relationship between sediment texture and potential fluid or gas seepage pathways.

Strengths

• Data originates from a targeted marine survey (SOL5754/GA0340) conducted by Geoscience Australia and the Australian Institute of Marine Science.
• Includes 111 distinct seabed sediment samples with laboratory analysis.
• Specific analytical method (laser diffractometer) is documented for grain size measurement.

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 single survey area on the Leveque Shelf.
