Results from version 4.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef. The model is forced with atmospheric, ocean boundary, tidal, and river data, and succeeded the GBR4_H2p0 model as the best available eReefs hydrodynamic results for its timespan. The dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.
Use Cases
- Simulating ocean currents and water circulation based on the 4km-resolution regional model.
- Analyzing the impact of river discharge on reef systems based on measured data from 64 rivers.
- Studying tidal influences on the Great Barrier Reef using the integrated global TPXO tide model.
- Validating hydrodynamic models by comparing hindcast results with observational data.
Strengths
- Model uses a 4km spatial resolution for detailed regional analysis.
- Forced with data from 64 rivers, providing detailed freshwater input.
- Integrates multiple high-quality forcing datasets including BARRA atmospheric reanalysis and BRAN2020 ocean reanalysis.
- Succeeds a previous model version (GBR4_H2p0) 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 bias inherent to the Great Barrier Reef region.
