Broad Sound Estuarine Sediment Geochemistry with Statistical Analysis

Analysis of estuarine sediments from Broad Sound, Queensland, applying Q-mode and R-mode factor analysis, discriminant analysis, and regression. The study identifies geochemical processes controlling concentrations of P2O5, Cu, Pb, and Zn in intertidal and supratidal zones. Research was published by the Australian Ocean Data Network, with a platform record last updated in April 2026.

Use Cases

• Classify sediment samples into intertidal and supratidal groups using Q-mode factor analysis on geochemical variables.
• Identify processes controlling P2O5, Cu, Pb, and Zn concentrations via R-mode factor analysis and correlation coefficients.
• Assess stability of pH and Eh readings over time using analysis of variance on measured variables.
• Model relationships between trace elements and environmental conditions using stepwise regression analysis.

Strengths

• Analysis applies multiple statistical techniques (factor analysis, discriminant analysis, regression) to validate findings.
• Study distinguishes geochemical processes for specific zones (intertidal vs. supratidal).

Limitations

• Sample size and number of measured variables are not specified.
• Underlying raw data tables are not directly available, only analysis results in report format.
