eReefs GBR1 Hydrodynamics v2.0: 1km Great Barrier Reef Model Results

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

Use Cases

• Simulate ocean currents and water circulation based on the 1km-resolution hydrodynamic model.
• Analyze the impact of river discharge on reef systems based on measured flow data from gauging stations.
• Study near-real-time environmental changes based on the model's daily update cycle.
• Validate broader-scale ocean models based on nesting within the 4km-resolution GBR4 model.

Strengths

• High-resolution 1km-scale modeling focused on the Great Barrier Reef shelf.
• Model incorporates multiple authoritative data sources: Bureau of Meteorology atmospheric data and Queensland DNRM river flow data.
• Ran with a daily update frequency in near-real-time mode.

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.
• Data formats (WMS, HTML) suggest it is served for visualization, which may limit direct analysis.
