eReefs GBR4: Great Barrier Reef Biogeochemistry and Sediments Model v3.1

Daily near-real-time model results from version 3.1 of the 4km-resolution biogeochemistry and sediments model for the Great Barrier Reef. The model was forced by a hydrodynamic model and catchment inputs from wet and dry tropics rivers, running until January 2024 when river-flow sensor damage halted updates. The dataset is provided by the Australian Ocean Data Network.

Use Cases

• Analyzing daily changes in water quality based on the near-real-time model outputs.
• Studying sediment transport and deposition patterns in the Great Barrier Reef at 4km resolution.
• Modeling the impact of river catchment inputs on coastal biogeochemistry using the Furnas relationships.
• Investigating the effects of the 2023/24 monsoon season on model forcing and data continuity.

Strengths

• Model outputs were updated daily in a near-real-time mode.
• Provides 4km-resolution regional-scale coverage of the Great Barrier Reef.
• Integrates hydrodynamic forcing and specific catchment input relationships.

Limitations

• Data updates ceased in January 2024 due to lost access to critical river-flow forcing data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
