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

The Great Barrier Reef is modeled at 4km resolution for biogeochemistry and sediment dynamics. This dataset contains results from version 3.1 of the model, forced by hydrodynamics and river inputs, and was updated daily in near-real-time until January 2024. The model configuration is named 'GBR4_H2p0_B3p1_Cfur_Dnrt' according to the eReefs naming protocol.

Use Cases

• Modeling sediment transport and deposition based on the 4km-resolution sediment model.
• Analyzing biogeochemical cycles (e.g., nutrients, chlorophyll) based on the regional-scale biogeochemistry model.
• Studying the impact of riverine inputs on reef systems based on the catchment forcing relationships.
• Assessing near-real-time environmental conditions based on the model's daily update cycle.

Strengths

• Model results are at a 4km spatial resolution, providing regional-scale detail.
• The model ran in near-real-time mode with daily updates, suggesting temporal granularity.
• Dataset is associated with a specific, documented model configuration (GBR4_H2p0_B3p1_Cfur_Dnrt).

Limitations

• Data updates ceased in January 2024 due to loss of 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.
