A study comparing phytoplankton and benthic microalgae across tidal creeks with and without treated sewage discharge. Concentrations of the sewage marker coprostanol decreased downstream, commensurate with declines in nitrogen and phosphorus, indicating sewage was the primary nutrient source. Primary productivity in the water column was nitrogen-limited without sewage and nitrogen-saturated with sewage.
Use Cases
- Modeling algal bloom dynamics based on nutrient loadings from sewage.
- Comparing phytoplankton and benthic microalgae responses to anthropogenic nutrient sources.
- Analyzing the spatial gradient of sewage markers and nutrient concentrations downstream from discharge points.
- Investigating nitrogen limitation and saturation in tropical estuarine water columns.
Strengths
- Data is based on an in-situ study comparing creeks with and without sewage discharge.
- Includes measurements of sewage-specific markers (coprostanol) alongside nutrient concentrations.
- Examines both phytoplankton and benthic microalgae communities.
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.
