GBR4_H2p0: Great Barrier Reef Hydrodynamic Model Results

Results from version 2.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef (GBR4). The model was forced with ocean boundary data from OceanMAPS, atmospheric data from ACCESS-R, tidal constituents from CSR, and river flow data from Queensland gauging stations. The model ran in near-real-time mode, updating daily, until January 2024.

Use Cases

• Analyze regional-scale ocean currents based on the 4km-resolution hydrodynamic model.
• Study tidal influences on reef ecosystems based on the 22 tidal constituents.
• Model river discharge impacts on coastal waters based on measured flow from 22 rivers.
• Assess near-real-time ocean state changes based on the daily updating model.
• Validate other oceanographic models based on the multi-source forcing data.

Strengths

• Model incorporates forcing data from multiple authoritative sources: OceanMAPS, ACCESS-R, CSR tide model, and QLD DNRM gauging stations.
• Includes measured river flow and temperature data for 22 rivers and estimated data for 49 additional rivers.
• Ran in near-real-time mode with daily updates until January 2024.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data collection was disrupted in January 2024 due to sensor damage during the monsoon season.
• Row count is unknown, which may limit suitability assessment.
