eReefs GBR1 River Tracers: Great Barrier Reef Hydrodynamic Model Results

Daily near-real-time passive river tracer results derived from the 1km-resolution GBR1 hydrodynamic model of the Great Barrier Reef. The model ran until January 2024, when the 2023/24 monsoon season damaged sensors and cut off critical river-flow forcing data. Results are provided by the Australian Ocean Data Network.

Use Cases

• Modeling river plume dispersion in the Great Barrier Reef based on passive tracer results.
• Analyzing the impact of river discharge on reef water quality based on hydrodynamic model outputs.
• Studying the effects of monsoon season events on coastal hydrodynamics based on the described operational timeline.

Strengths

• Results are derived from a 1km-resolution shelf-scale hydrodynamic model.
• Model ran in near-real-time mode with daily updates until January 2024.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data collection was interrupted in January 2024 due to sensor damage, limiting temporal coverage.
