Geochemical Analysis of Estuarine Sediments from Broad Sound, Queensland

Q-mode factor analysis classified estuarine sediment samples from Broad Sound, Queensland, into two geologically distinct groups representing intertidal and supratidal deposition. The dataset, hosted by the Australian Ocean Data Network, includes analyses of variables such as P2O5, Cu, Pb, Zn, pH, and Eh to identify processes controlling trace element concentrations. It was last updated on 2026-04-16.

Use Cases

• Classifying sediment depositional environments based on geochemical variables mentioned in the description
• Modeling the relationship between pH/Eh and trace metal (Cu, Pb, Zn) mobility in sediments
• Identifying controlling factors for P2O5 concentration in intertidal versus supratidal zones
• Applying statistical validation techniques like discriminant analysis and canonical correlation to geochemical data

Strengths

• Analysis includes multiple statistical validation methods (Q-mode factor analysis, stepwise discriminant analysis, canonical correlation).
• Specific geochemical variables (P2O5, Cu, Pb, Zn, pH, Eh) and their controlling processes are identified.
• Dataset provenance is linked to the Australian Ocean Data Network.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
