eReefs GBR4 River Tracers v2.0: Great Barrier Reef Hydrodynamic Model Output

eReefs GBR4 river tracers v2.0 contains passive river tracer results from the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef. The model ran in near-real-time mode, updating daily, until January 2024 when sensor damage during the monsoon season halted the critical river-flow forcing dataset. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-04.

Use Cases

• Modeling river plume dispersion and connectivity based on passive tracer results.
• Analyzing near-real-time hydrodynamic conditions in the Great Barrier Reef until January 2024.
• Studying the impact of river discharge on reef ecosystems using derived tracer data.
• Validating other hydrodynamic or water quality models against the GBR4_H2p0_Rivers simulation.

Strengths

• Model output is derived from a 4km-resolution regional-scale hydrodynamic model.
• The model ran in near-real-time mode with daily updates until January 2024.
• Dataset follows a defined simulation naming protocol (GBR4_H2p0_Rivers).

Limitations

• Data collection was halted in January 2024 due to sensor damage, limiting temporal coverage.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
