Geochemical Analysis of Estuarine Sediments from Broad Sound, Queensland

A dataset containing geochemical measurements from estuarine sediment samples collected in Broad Sound, Queensland. The data was analyzed using Q-mode and R-mode factor analysis, stepwise discriminant analysis, and analysis of variance to classify depositional environments and trace element behavior. The dataset is hosted by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Classifying sediment depositional environments based on geochemical signatures mentioned in the description
• Modeling the adsorption and release of trace metals (Cu, Pb, Zn) under varying pH and Eh conditions described in the analysis
• Identifying processes controlling phosphate (P2O5) concentration in relation to clay particles and organic carbon as outlined
• Applying statistical validation techniques like stepwise discriminant analysis to geological sample groups

Strengths

• Analysis validated by multiple statistical techniques including Q-mode factor analysis and stepwise discriminant analysis.
• Specific geochemical processes for elements like P2O5, Cu, Pb, and Zn are identified and described.
• Dataset is hosted by an authoritative organization, the Australian Ocean Data Network.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study area in Broad Sound.
