Biologically relevant macronutrients, including nitrate, silicate, phosphate, and ammonia, were measured at multiple coastal sites. Nitrate and phosphate concentrations showed clear seasonal peaks in winter, while ammonium levels remained consistently low. The data was aggregated by the Australian Ocean Data Network and last updated in July 2026.
Use Cases
- Model seasonal nutrient cycles based on described winter peaks in nitrate and phosphate.
- Analyze spatial nutrient distribution based on described differences between sites 1, 5, and 9.
- Investigate riverine influence on coastal silicate concentrations based on the mention of River Derwent outflow.
- Assess baseline ammonium levels in coastal waters based on the described median concentrations below 0.5 μM.
Strengths
- Includes measurements for multiple biologically relevant macronutrients: nitrate + nitrite, silicate, phosphate, and ammonia.
- Description reveals clear seasonal patterns, such as winter peaks for nitrate and phosphate.
- Spatial context is provided, linking site-specific silicate levels to the flow of the River Derwent.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
