eReefs GBR1 Hydrodynamics: 1km Great Barrier Reef Model Results

Results from version 2.0 of the 1km-resolution shelf-scale hydrodynamic model of the Great Barrier Reef, nested within a 4km-resolution model. The model ran in near-real-time mode, updating daily, until January 2024 when sensor damage during the monsoon season halted access to critical river-flow data. The dataset is associated with the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling ocean currents and water properties based on the 1km-resolution hydrodynamic model.
• Analyzing near-real-time environmental conditions based on the model's daily update cycle.
• Studying river plume dynamics based on the incorporation of measured river flow data.
• Assessing shelf-scale circulation patterns based on the nested GBR1 and GBR4 model configuration.

Strengths

• High-resolution 1km-scale model output for detailed regional analysis.
• Incorporates measured river flow data from gauging stations for boundary conditions.
• Model was run in a near-real-time mode with daily updates until January 2024.

Limitations

• Data collection was interrupted in January 2024 due to sensor damage, limiting recent 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.
