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

Passive river tracer results derived from the eReefs 4km-resolution hydrodynamic model of the Great Barrier Reef, forced with atmospheric, ocean, tide, and river boundary data. The model ran in hindcast mode and is described as complete, succeeding a previous version as the best available for its timespan. The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling pollutant dispersion from rivers into the Great Barrier Reef based on passive tracer results.
• Assessing contributions of 35 significant rivers to reef water quality for environmental report cards.
• Validating hydrodynamic models using hindcast data from the eReefs GBR4 configuration.
• Analyzing the impact of river boundaries from catchment models on regional-scale ocean simulations.

Strengths

• Results are derived from a 4km-resolution regional-scale hydrodynamic model.
• Model is forced with multiple high-quality inputs, including BARRA atmospheric reanalysis and BRAN2020 ocean boundaries.
• Dataset is described as complete and succeeds a previous version as the best available for its timespan.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific model configuration and source platforms.
