Sediment and Water Quality Relationships in Southwest Australian Estuaries

Twelve shallow estuaries in southwest Western Australia provide data on sediment loads and nutrient concentrations. The Australian Ocean Data Network published this research examining relationships between sediment total nitrogen, phosphorus, organic carbon, and water column chlorophyll a. The dataset was last updated in April 2026.

Use Cases

• Model sediment total organic carbon (TOC) to total sulfur (TS) ratios as a function of calculated sediment load.
• Analyze the curvilinear relationship between the sediment weathering index and organic matter δ13C isotopic values.
• Predict water column total nutrient (nitrogen and phosphorus) concentrations based on sediment load patterns.
• Investigate correlations between sediment TS:Fe(II) ratios and burial rates due to sulfate reduction.

Strengths

• Data covers 12 distinct estuaries, allowing for comparative analysis.
• Includes calculated sediment loads across a range from 0.2 to 10.8 kg m-2 year-1.
• Examines multiple interrelated variables: sediment chemistry, water column nutrients, and isotopic signatures.

Limitations

• The specific row count and sample size per estuary are not provided.
• Geographic scope is limited to wave-dominated estuaries in a single region of Australia.
• File format is HTML, which may require extraction to structure the underlying data.
