Sediment and Water Quality in 12 Wave-Dominated Estuaries of Southwest Australia

12 estuaries in southwest Western Australia are examined for surface sediment and water column nutrient concentrations. The dataset includes calculated sediment loads ranging from 0.2 to 10.8 kg m-2 year-1 and explores relationships with sediment total nitrogen, phosphorus, organic carbon, and sulfur. It was published by Geoscience Australia Data and last updated on 2026-04-30.

Use Cases

• Modeling the relationship between sediment load and nutrient concentrations based on the described inverse correlation.
• Analyzing the impact of soil versus bedrock erosion on sediment organic matter based on the described weathering index and isotopic patterns.
• Assessing water quality problems associated with intermediate sediment loads as indicated in the description.
• Investigating the role of sulfate reduction in organic matter degradation based on TOC:TS and TS:Fe(II) ratios.

Strengths

• Covers 12 distinct estuaries, providing a comparative basis.
• Includes specific sediment load measurements ranging from 0.2 to 10.8 kg m-2 year-1.
• Analyzes multiple sediment and water quality parameters: total nitrogen, phosphorus, organic carbon, chlorophyll a, and sulfur.

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 estuaries studied in southwest Western Australia.
