The dataset from the Australian Ocean Data Network examines the effect of secondary treated sewage on algal production, biomass, and species composition in tropical tidal creeks. It compares phytoplankton and benthic microalgae responses across creeks with and without sewage discharge, measuring nutrients, coprostanol, primary productivity, and chlorophyll a. The study was last updated on 2026-04-10.
Use Cases
- Modeling nitrogen and phosphorus limitation in phytoplankton based on nutrient concentration data.
- Analyzing the spatial gradient of sewage impact based on coprostanol and nutrient measurements.
- Comparing primary productivity responses between phytoplankton and benthic microalgae communities.
- Investigating algal community composition stability based on pigment proportion data.
Strengths
- Data is derived from a controlled in-situ study comparing creeks with and without sewage discharge.
- Includes multiple measured variables: coprostanol, nitrogen, phosphorus, primary productivity, and chlorophyll a.
- Focuses on a specific, ecologically relevant scenario of tropical estuarine tidal creeks.
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 tropical estuary.
