GBR4_H2p0_B3p1_Cfur_Dnrt: Great Barrier Reef Biogeochemistry Model

eReefs GBR4 biogeochemistry and sediments v3.1 provides results from a 4km-resolution regional-scale model of the Great Barrier Reef. The model, forced by hydrodynamic data and river catchment inputs, simulated biogeochemical and sediment processes in near-real-time until January 2024. This dataset is a key output of the eReefs simulation protocol for marine ecosystem monitoring.

Use Cases

• Tracking sediment plumes and water clarity based on the 4km-resolution sediment transport model.
• Analyzing nutrient cycles and algal blooms using the biogeochemistry simulation outputs.
• Assessing catchment runoff impacts on reef health via the Furnas relationships for river inputs.
• Validating remote sensing data with daily-updated, near-real-time model hindcasts.

Strengths

• Provides high-resolution (4km) regional-scale coverage of the entire Great Barrier Reef.
• Ran in near-real-time with daily updates, offering timely environmental data.
• Follows a standardized eReefs simulation naming protocol (GBR4_H2p0_B3p1_Cfur_Dnrt).

Limitations

• Critical river-flow forcing data was lost after January 2024 due to sensor damage, halting the near-real-time updates.
• Column names and specific data structure are not described in the available metadata.
• Exact dataset size, row count, and license information are not provided.
