Fitzroy River Basin Sediment Sources with Geochemical and Bayesian Analysis

Sediment sources to the Fitzroy River coastal zone have been identified and quantified using an integrated geochemical and modelling approach. The dataset, provided by the Australian Ocean Data Network, indicates a sediment composition consistent with derivation from mixed catchment sources. A Bayesian statistical model revealed changes in catchment sediment sources over time, with the proportion of basaltic material increasing and becoming dominant with an estimated enrichment of ca. 3 relative to catchment abundances.

Use Cases

• Modeling changes in sediment source contributions over time based on Bayesian statistical analysis
• Analyzing the impact of rainfall events and land-use changes on coastal sediment composition
• Targeting land management practices to reduce sediment loads from specific catchment areas
• Studying the homogenization effect of hydrodynamic processes on coastal sediment geochemistry

Strengths

• Integrated geochemical and Bayesian modelling approach for source identification
• Analysis covers temporal changes in sediment sources throughout the Holocene
• Specific finding of basaltic material enrichment by a factor of ca. 3

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and file size are unknown, which may limit suitability assessment
