The Australian Ocean Data Network dataset examines sediment and water column nutrient concentrations across 12 shallow estuaries in southwest Western Australia. It analyzes relationships between sediment loads, sediment composition, and water quality, with sediment loads ranging from 0.2 to 10.8 kg m-2 year-1. The dataset was last updated on April 16, 2026.
Use Cases
- Modeling sediment load impacts on water quality based on total nitrogen and phosphorus concentrations.
- Analyzing relationships between sediment composition and weathering indices based on sediment total organic carbon and sulfur ratios.
- Investigating the role of soil versus bedrock erosion in estuary sedimentation patterns.
- Assessing the potential moderating effect of flushing on sediment impacts.
Strengths
- Focuses on 12 specific estuaries with average water depths less than 4 meters.
- Includes calculated sediment loads ranging from 0.2 to 10.8 kg m-2 year-1.
- Analyzes multiple sediment components including total nitrogen, phosphorus, organic carbon, 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 data_gov_au, focusing solely on southwest Western Australia.
