Two transects across the Derwent estuary were sampled in 2025, measuring temperature, salinity, chlorophyll-a, nutrients, and other parameters. Sampling included CTD sensor measurements, plankton net tows, Secchi disk readings, and water sample collection. The dataset is hosted by the Australian Ocean Data Network and was last updated in July 2026.
Use Cases
- Modeling salt wedge dynamics based on salinity and temperature profiles mentioned in the description
- Analyzing nutrient distribution (nitrate, ammonia, phosphate, silicate) across the estuary
- Correlating chlorophyll-a concentration with fluorescence and dissolved oxygen levels for phytoplankton studies
- Assessing water clarity and turbidity using Secchi disk measurements and sensor data
Strengths
- Includes measurements for 10 distinct water properties, such as temperature, salinity, and multiple nutrients
- Sampling covers 7 specific geographic coordinates across two transects in the Derwent estuary
- Data collection involved multiple methods: CTD sensors, plankton nets, Secchi disks, and lab water samples
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
