GBR4_H2p0_B3p1_Cq3p_Dhnd: Pre-Industrial Catchment Model of the Great Barrier Reef

December 2018 to April 2019 model results from a 4km-resolution regional-scale biogeochemistry and sediments simulation of the Great Barrier Reef. The dataset, part of the eReefs simulation suite, represents a hindcast run with a pre-industrial catchment scenario, forced by a hydrodynamic model and specific catchment inputs. It serves as a comparative benchmark alongside baseline and reduced-load catchment scenarios.

Use Cases

• Benchmarking water quality under pre-industrial conditions based on the described catchment scenario.
• Analyzing sediment transport patterns from the regional-scale sediments model.
• Comparing hydrodynamic forcing impacts using the version 2.0 hydrodynamic model outputs.
• Studying temporal changes in reef biogeochemistry over the 5-month simulation period.

Strengths

• Provides a specific, high-resolution (4km) geospatial model of a major ecosystem.
• Part of a defined comparative suite including baseline and reduced-load scenarios, enabling controlled analysis.
• Covers a continuous 5-month time range from December 2018 to April 2019.

Limitations

• Critical metadata is missing, including column/variable definitions, data volume, license, and author information.
• The description contains an apparent date conflict, stating a run from 'December 01, 2018 to June 30, 2018'.
• Documentation appears limited to a repeated technical description without access to the underlying data structure.
