Fitzroy River Basin Sediment Source Analysis via Geochemical and Bayesian Modelling

Geochemical and Bayesian modelling data identify sediment sources in the Fitzroy River coastal zone. The study found basaltic material is now the dominant catchment source, with an estimated enrichment of approximately 3 relative to catchment abundances. Research was conducted by the Australian Ocean Data Network and the record was last updated in April 2026.

Use Cases

• Model temporal changes in sediment source contributions, such as basaltic material, using Bayesian statistical methods.
• Analyze geochemical composition data to identify catchment soil types like basaltic soils delivered to the coastal zone.
• Correlate sediment source variations with historical factors like rainfall event intensity and land-use changes following European settlement.
• Assess the impact of large flow events and estuary hydrodynamics on the deposition of different catchment soil types.

Strengths

• Analysis covers sediment records throughout the Holocene period.
• Integrated approach using both geochemical data and Bayesian statistical modelling.

Limitations

• Specific sample size, row count, and column details are unavailable.
• Primary data format is an HTML publication, limiting direct machine-readability.
