eReefs GBR4: Great Barrier Reef Biogeochemistry and Sediments Model at 4km Resolution

Version 3.1 of the 4km-resolution biogeochemistry and sediments model for the Great Barrier Reef, forced by hydrodynamic data and river catchment inputs. The model ran in near-real-time with daily updates until January 2024, when sensor damage during the monsoon season halted river-flow data access. Results are provided by the Australian Ocean Data Network.

Use Cases

• Modeling sediment transport and deposition patterns based on the 4km-resolution regional-scale model.
• Analyzing biogeochemical cycles (e.g., nutrients, chlorophyll) in the Great Barrier Reef based on the near-real-time simulation outputs.
• Studying the impact of river catchment inputs from wet and dry tropics on reef water quality based on the Furnas relationships used.
• Assessing temporal changes in reef conditions up to January 2024 based on the daily update schedule.

Strengths

• High-resolution 4km regional-scale model output for the entire Great Barrier Reef.
• Near-real-time daily updates were produced until operations ceased in January 2024.
• Model integrates hydrodynamic forcing and detailed river catchment inputs using established Furnas relationships.

Limitations

• Data collection was interrupted in January 2024 due to sensor damage, limiting temporal coverage.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description metadata is limited; actual data quality and format require manual inspection.
