12 estuaries in southwest Western Australia are examined for surface sediment and water column nutrient concentrations. The data includes calculated sediment loads ranging from 0.2 to 10.8 kg m-2 year-1 and explores relationships between sediment composition, weathering, and water quality. The dataset is provided by Geoscience Australia Data and was last updated in April 2026.
Use Cases
- Modeling the relationship between sediment loads and nutrient concentrations based on the described inverse correlation.
- Analyzing the impact of soil versus bedrock erosion on sediment organic matter composition based on the weathering index and isotopic data.
- Assessing water quality problems associated with intermediate sediment loads as indicated in the study findings.
- Investigating the role of sulfate reduction in organic matter degradation based on TOC:TS and TS:Fe(II) ratio correlations.
Strengths
- Data covers 12 distinct estuaries, providing a comparative basis.
- Includes specific measured ranges for sediment loads (0.2 to 10.8 kg m-2 year-1) and water depths (<4 m).
- Analysis links multiple variables: sediment nutrients, organic carbon, sulfur, iron, isotopic signatures, and water column nutrients.
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 Western Australia.
