GBR4_H2p0_B3p1_Cq3b_Dhnd: Great Barrier Reef Biogeochemistry Baseline Model

December 1, 2010 to April 30, 2019 is the temporal coverage for this 4km-resolution model output of the Great Barrier Reef. The dataset contains results from a biogeochemistry and sediments model (version 3.1) forced by a hydrodynamic model (version 2.0) and a baseline catchment scenario. It is part of a suite of simulations that includes pre-industrial and reduced-load catchment scenarios for comparative analysis.

Use Cases

• Analyzing sediment transport patterns based on the 4km-resolution biogeochemistry model.
• Comparing baseline water quality conditions against pre-industrial and reduced-load catchment scenarios.
• Studying temporal trends in reef biogeochemistry from December 2010 to April 2019.
• Validating hydrodynamic model outputs using the coupled biogeochemistry results.

Strengths

• Provides a specific 8.5-year temporal coverage from December 2010 to April 2019.
• Offers high-resolution (4km) spatial data for the entire Great Barrier Reef region.
• Is part of a formally named and structured modeling suite (eReefs GBR4) allowing for scenario comparison.

Limitations

• Column names and data structure are not provided in the available metadata.
• Dataset size and row counts are unknown, complicating assessment of data volume.
• Conflicting 'last updated' timestamps (2026-06-05 and 2026-03-21) create uncertainty about metadata freshness.
