eReefs GBR4 River Tracers v4.0: Passive Tracer Results for 35 Great Barrier Reef Rivers

Passive tracer results for 35 rivers significant to the Reef 2050 Water Quality Improvement Plan, derived from the eReefs 4km-resolution regional-scale hydrodynamic model (GBR4). The model is forced with atmospheric reanalysis, ocean boundary data, tidal models, and measured river data. This dataset, produced by the Australian Ocean Data Network, succeeds the GBR4_H2p0_Rivers model as the best available eReefs river tracer results for its timespan.

Use Cases

• Modeling pollutant transport and fate based on passive river tracers mentioned in the description
• Assessing river contributions to reef water quality for the Reef 2050 Plan report cards
• Calibrating hydrodynamic models using results from the GBR4_H4p0_ABARRAr2_OBRAN2020_FG2Gv3_Dhnd_Rivers configuration

Strengths

• Results from a 4km-resolution regional-scale hydrodynamic model
• Includes data for 35 rivers of significance to the Reef 2050 Plan
• Model is forced with multiple high-quality inputs including BARRA reanalysis and BRAN2020 ocean data

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
