GBR4_H2p0_B3p1_Cq3R_Dhnd: Great Barrier Reef Water Quality Hindcast Under Reduced Loads

Version 3.1 of the 4km-resolution biogeochemistry and sediments model for the Great Barrier Reef, forced by hydrodynamic data and a reduced-loads catchment scenario. The scenario applies percentage reductions in DIN, PN, PP, and TSS as specified in the Reef 2050 Water Quality Improvement Plan 2017-2022, adjusted for cumulative reductions achieved between 2014 and 2019. This dataset is part of a suite of eReefs simulations including baseline and pre-industrial scenarios.

Use Cases

• Assessing the projected impact of reduced anthropogenic loads on Great Barrier Reef water quality based on the specified nutrient and sediment reduction targets.
• Comparing water quality outcomes between baseline, reduced-loads, and pre-industrial catchment scenarios described in the simulation suite.
• Validating the effectiveness of the Reef 2050 Water Quality Improvement Plan (2017-2022) targets using hindcast model results.
• Studying the spatial distribution (4km resolution) of biogeochemical parameters under modified catchment conditions.

Strengths

• Model outputs are based on a specific, policy-reduced loads scenario derived from the Reef 2050 Water Quality Improvement Plan.
• Results are part of a comparative suite including baseline and pre-industrial scenarios, allowing for controlled analysis.
• Spatial resolution is explicitly stated as 4km.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific eReefs model configuration.
