eReefs GBR1: 1km Hydrodynamic Model of the Great Barrier Reef

Version 2.0 of the 1km-resolution shelf-scale hydrodynamic model for the Great Barrier Reef, nested within a 4km-resolution model. The Australian Ocean Data Network maintained this model, which ran in near-real-time with daily updates until January 2024 when sensor damage during the monsoon season halted operations.

Use Cases

• Modeling coastal ocean currents based on the 1km-resolution hydrodynamic outputs.
• Analyzing the impact of river discharge on reef systems based on the incorporation of measured flow data from gauging stations.
• Studying near-real-time oceanographic conditions based on the model's daily update cycle.
• Validating broader-scale ocean models based on the nesting within the 4km-resolution GBR4 model data.

Strengths

• High-resolution 1km-scale modeling for the Great Barrier Reef shelf.
• Incorporates multiple authoritative data sources: Bureau of Meteorology atmospheric data and Queensland DNRM river flow data.
• Model was operational in near-real-time with daily updates.

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 and dataset size are unknown, which may limit suitability assessment.
