eReefs GBR4 Hydrodynamics v4.0: 4km Great Barrier Reef Model

The Great Barrier Reef region is modeled by version 4.0 of the 4km-resolution eReefs hydrodynamic model (GBR4). This hindcast simulation is forced with atmospheric data from BARRA, ocean boundaries from BRAN2020, tides from TPXO, and river inputs from 64 catchment models. The dataset is produced by the Australian Ocean Data Network and is presented as the best available eReefs hydrodynamic model results for its timespan.

Use Cases

• Simulate ocean currents and water properties based on the 4km-resolution hydrodynamic model.
• Analyze the impact of riverine inputs on coastal waters based on data from 64 river boundaries.
• Validate other marine models using the hindcast results from this comprehensive regional simulation.
• Study tidal influences on reef systems based on the integrated global TPXO tide model.

Strengths

• Model is described as the 'best available eReefs hydrodynamic model results for its timespan'.
• Integrates multiple high-quality forcing datasets: BARRA atmospheric reanalysis, BRAN2020 ocean reanalysis, TPXO tides, and river data from 64 catchments.
• Provides a complete hindcast simulation at a regional scale with 4km resolution.

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 source models and the data_gov_au platform.
