eReefs GBR4 River Tracers: Passive Tracer Results for 35 Great Barrier Reef Rivers

Passive tracer results for 35 significant rivers, derived from the eReefs 4km-resolution hydrodynamic model of the Great Barrier Reef. The model is forced with high-resolution atmospheric, ocean, tide, and river boundary data from sources like BARRA and BRAN2020. This dataset, produced by the Australian Ocean Data Network, is the best available eReefs river tracer model for its timespan and supports the Reef 2050 Water Quality Improvement Plan.

Use Cases

• Modeling pollutant dispersal from river sources based on passive tracer results.
• Assessing water quality improvement plans based on hydrodynamic model outputs.
• Analyzing the impact of river boundaries and atmospheric forcing on coastal systems.
• Supporting environmental report cards for the Great Barrier Reef based on the Reef 2050 Plan.

Strengths

• Derived from a 4km-resolution regional-scale hydrodynamic model, providing detailed spatial coverage.
• Forced with high-quality inputs from BARRA atmospheric reanalysis and BRAN2020 ocean reanalysis.
• Contains results for 35 rivers of significance to a major national water quality plan.
• Succeeds a previous model version as the best available for its timespan.

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 and temporal bias inherent to the specific model configuration and input sources.
