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, contains results from statistical and mathematical analyses identifying processes controlling concentrations of P2O5, Cu, Pb, and Zn. Last updated on 2026-04-10, the data explores trace element behavior under varying pH and Eh conditions.

Use Cases

• Classifying sediment deposition zones based on geochemical signatures mentioned in the description
• Modeling the relationship between pH/Eh and trace element release for Cu, Pb, and Zn
• Identifying factors controlling P2O5 concentration in relation to clay particles and organic carbon
• Analyzing the stability of pH and Eh readings over time using analysis of variance

Strengths

• Analysis is supported by multiple statistical methods: Q-mode factor analysis, discriminant analysis, and canonical correlation analysis
• Specific geochemical processes for P2O5, Cu, Pb, and Zn are identified in the description

Limitations

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