Superseded Great Barrier Reef Biogeochemical Model Data

Comprising results from an early version of the 1km-resolution shelf-scale biogeochemical model of the Great Barrier Reef. The model, version 924, was forced by version 1.85 of the eReefs hydrodynamic model and includes improvements for optical calculations, sediment loads, and oxygen diagnostics. It has been superseded by a newer model version.

Use Cases

• Analyze sediment tracer 'Dust' concentrations to study sediment transport patterns in the Great Barrier Reef.
• Compare optical calculations from this version with newer model versions to assess improvements in water clarity simulations.
• Study oxygen mass conservation diagnostics to evaluate biogeochemical model performance.
• Examine corrected particulate and dissolved loads from the Normanby River to understand nutrient inputs.

Strengths

• Provides data from a 1km-resolution shelf-scale model of the Great Barrier Reef.
• Includes specific model improvements such as corrected Normanby River loads and a 'Dust' sediment tracer.
• Model was forced by a specific hydrodynamic model version (eReefs GBR 1 km resolution, version 1.85).

Limitations

• The dataset is explicitly marked as superseded by a newer version (GBR1_H2p0_B3p2_Cfur_Dnrt).
• Key metadata such as row count, column names, and data size are unknown.
• Data is available only in HTML and PNG formats, limiting direct numerical analysis.
