Biologically relevant macronutrient measurements from coastal waters in south eastern Tasmania. The data includes nitrate + nitrite, silicate, phosphate, and ammonia, showing clear seasonal patterns such as winter peaks for nitrate and phosphate. The dataset is provided by the Australian Ocean Data Network and was last updated in July 2026.
Use Cases
- Model seasonal nutrient cycles based on described winter peaks in nitrate and phosphate.
- Analyze riverine influence on silicate concentrations based on the described flow from the River Derwent.
- Study spatial nutrient gradients based on the described differences between sampling sites.
- Investigate ammonium background levels based on the described median concentrations generally below 0.5 μM.
Strengths
- Includes multiple biologically relevant macronutrients: nitrate + nitrite, silicate, phosphate, and ammonia.
- Shows clear seasonal trends, such as nitrate and phosphate peaking in winter.
- Provides spatial context with specific site comparisons, such as sites 1, 9, and 5 having the highest silicate.
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 on a specific region of Tasmania.
