eReefs GBR4 Hydrodynamics v2.0: 4km Great Barrier Reef Model

Version 2.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef, forced with ocean boundary data from the BlueLink OceanMAPS model and atmospheric data from the Bureau of Meteorology ACCESS-R model. The model incorporated tide data from 22 constituents of the global CSR tide model and river boundary data from 71 rivers, including measured flows from 22 QLD DNRM stations. It ran in near-real-time, updating daily, until January 2024 when sensor damage during the monsoon season halted operations.

Use Cases

• Simulating ocean currents and water circulation based on the 4km-resolution hydrodynamic model.
• Analyzing the impact of riverine freshwater and nutrient inputs based on data from 71 river boundaries.
• Studying tidal influences on reef systems based on 22 tidal constituents from the CSR model.
• Investigating near-real-time environmental changes based on the model's daily update cycle.

Strengths

• Model results are based on forcing from established operational systems like OceanMAPS and ACCESS-R.
• River boundary data incorporates measured stream flow from 22 specific gauging stations.
• Tidal forcing is derived from 22 constituents of a global tide model.

Limitations

• The near-real-time data stream was halted in January 2024 due to sensor damage, limiting temporal coverage.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
