eReefs GBR1 Hydrodynamics: Great Barrier Reef 1km Model Results

The Great Barrier Reef is modeled by the 1km-resolution shelf-scale hydrodynamic model GBR1 version 2.0. The model ran in near-real-time mode, updating daily, until January 2024 when sensor damage during the monsoon season halted operations. Results are nested within a 4km model and incorporate atmospheric and river flow data from Australian agencies.

Use Cases

• Analyze ocean circulation patterns based on the 1km-resolution hydrodynamic model
• Study the impact of river discharge on reef systems based on incorporated gauging station data
• Monitor near-real-time environmental changes based on the model's daily update cycle
• Validate and compare hydrodynamic models based on the nested GBR4 model framework

Strengths

• Model results are at 1km resolution, providing detailed spatial data
• The model incorporated measured river flow data from gauging stations
• It ran in a near-real-time mode with daily updates until January 2024

Limitations

• Data collection 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 is unknown, which may limit suitability assessment
