Superseded Great Barrier Reef Hydrodynamic Model Results

Results from version 1.85 of the 4 km resolution regional-scale hydrodynamic model of the Great Barrier Reef. The model was forced with BlueLink OceanMAPS and ACCESS-R atmospheric data, incorporated 22 tidal constituents, and included 22 river boundaries with stream flow and temperature data. This dataset has been superseded by GBR4_H2p0 and contains known salinity errors from incorrect rainfall forcing in 2015.

Use Cases

• Analyze hydrodynamic patterns using the 4 km resolution model grid for the Great Barrier Reef region.
• Study the impact of 22 incorporated river boundaries with stream flow and temperature data on coastal salinity.
• Reference historical model outputs, noting the known salinity errors from incorrect rainfall forcing in 2015 results.
• Compare tidal influences using the 22 tidal constituents derived from the global CSR tide model.

Strengths

• Provides results from a 4 km resolution hydrodynamic model, offering detailed spatial coverage of the Great Barrier Reef.
• Model incorporates data from 22 river boundaries and 22 tidal constituents for boundary forcing.
• Dataset is archived by custodians, preserving a specific historical model version (GBR4_H1p85) for reference.

Limitations

• Dataset is superseded and contains known scientific errors, specifically incorrect rainfall forcing leading to salinity errors in 2015 results.
• Access is restricted to an archive copy available only on request, limiting immediate usability.
• Specific data volume (rows, size) and column structure are unknown from the provided description.

Provenance

Source

Australian Ocean Data Network, derived from the eReefs GBR4 hydrodynamic model.

Collection Method

Outputs from version 1.85 of a 4 km resolution hydrodynamic model forced with oceanographic and atmospheric data.

Time Range

Temporal coverage is not explicitly stated, but the model version was published for reference in a January 2016 report.

Freshness

Dataset is superseded; last metadata update was 2026-03-21, but the model results are from an older, archived version.

Geography

Great Barrier Reef region, Australia.
