Seabed Sediment Grain Size Data from the Leveque Shelf Marine Survey

111 seabed sediment samples from the Leveque Shelf were analyzed for grain size using a laser diffractometer. Geoscience Australia and the Australian Institute of Marine Science collected this data in May 2013 to assess the CO2 storage potential of the Browse Basin. The survey aimed to identify evidence of gas seepage and map seabed habitats related to geological structures.

Use Cases

• Modeling sediment transport and deposition based on laser-measured grain size distributions.
• Assessing seabed integrity for carbon storage projects based on sediment composition data.
• Correlating seabed habitats with underlying geology using sediment texture and carbonate content.
• Identifying potential fluid migration pathways by analyzing sediment samples near fault structures.

Strengths

• Includes 111 distinct seabed sediment samples.
• Grain size analysis was performed using a standardized laser diffractometer method.
• Data collection was part of a targeted government survey (SOL5754/GA0340) under the National CO2 Infrastructure Plan.

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.
