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

Passive tracer results for 35 significant rivers, derived from version 4.0 of the eReefs 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef (GBR4). The model ran in hindcast mode and is complete, succeeding the GBR4_H2p0_Rivers model as the best available eReefs river tracer results for its timespan. It was published by the Australian Ocean Data Network and last updated on 2026-04-18.

Use Cases

• Modeling river plume dispersion based on passive tracer results for 35 significant rivers.
• Assessing water quality contributions for the Reef 2050 Water Quality Improvement Plan based on the described model outputs.
• Analyzing hydrodynamic influences on the Great Barrier Reef based on the 4km-resolution regional-scale model.
• Comparing river tracer results with previous model versions (e.g., GBR4_H2p0_Rivers) for temporal analysis.

Strengths

• Results are derived from a 4km-resolution regional-scale hydrodynamic model.
• Model is forced with multiple high-quality data sources including BARRA atmospheric reanalysis and BRAN2020 ocean boundaries.
• Dataset contains results for 35 rivers of significance to the Reef 2050 Water Quality Improvement Plan.
• The model is described as complete and the best available eReefs river tracer model results 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 bias inherent to the Great Barrier Reef region.
