Southwest Western Australia's wave-dominated estuaries are examined for surface sediment and water column nutrient concentrations. The dataset likely contains measurements for 12 estuaries with sediment loads ranging from 0.2 to 10.8 kg m-2 year-1, exploring relationships between sediment composition, weathering, and water quality. It was published by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Modeling the relationship between sediment load and nutrient concentrations based on total nitrogen and phosphorus data.
- Analyzing the impact of soil versus bedrock erosion on sediment geochemistry based on weathering index and organic matter 13C values.
- Investigating the role of sulfate reduction in organic matter degradation based on TOC:TS and TS:Fe(II) ratios.
- Assessing water quality problems associated with intermediate sediment loads mentioned in the description.
Strengths
- Covers 12 distinct estuaries with average water depths under 4 meters.
- Reports calculated sediment loads across a quantified range from 0.2 to 10.8 kg m-2 year-1.
- Examines multiple interrelated variables: sediment nutrients, water column nutrients, chlorophyll a, and geochemical ratios.
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 data_gov_au, focusing solely on southwest Western Australia.
