eReefs GBR4: 4km Biogeochemistry and Sediment Model of the Great Barrier Reef

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 mode, updating daily, until January 2024 when sensor damage halted river-flow data collection. This dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling sediment transport and deposition patterns based on the 4km-resolution sediment model.
• Analyzing biogeochemical cycles (e.g., nutrients, chlorophyll) in the Great Barrier Reef based on the regional-scale model output.
• Studying the impact of river catchment inputs on reef ecosystems based on the Furnas relationships for wet and dry tropics rivers.
• Investigating near-real-time environmental changes until early 2024 based on the model's daily update cycle.

Strengths

• Model outputs are at a 4km spatial resolution, providing regional-scale detail.
• The dataset represents a specific, documented model configuration (GBR4_H2p0_B3p1_Cfur_Dnrt).
• Data was produced in a near-real-time operational mode with daily updates.

Limitations

• The near-real-time data stream was interrupted in January 2024 due to lost sensor data for river-flow forcing.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
