GBR1_H2p0_B3p2_Cfur_Dnrt: Great Barrier Reef Biogeochemistry Model Results v3.2

The Great Barrier Reef is covered by results from version 3.2 of a 1km-resolution regional-scale biogeochemistry and sediments model (GBR1). The model ran in near-real-time, updating daily, until January 2024 when sensor damage halted operations. This dataset was retired by its authors in February 2026 due to an error causing unrealistic Chlorophyll-a levels.

Use Cases

• Studying historical biogeochemical model outputs for the Great Barrier Reef based on the described 1km-resolution model.
• Analyzing sediment transport patterns based on the described regional-scale sediments model component.
• Investigating the impact of river catchment inputs on reef systems based on the mentioned Furnas relationships for wet and dry tropics rivers.
• Examining the effects of lost river-flow forcing data on model continuity based on the described operational halt in January 2024.

Strengths

• Model results are at 1km spatial resolution for the Great Barrier Reef region.
• The model configuration follows a specific naming protocol (GBR1_H2p0_B3p2_Cfur_Dnrt) documented in the description.
• The dataset's retirement reason and specific error (abnormally high Chlorophyll-a) are explicitly documented.

Limitations

• The dataset was retired in February 2026 due to a scientific error producing unrealistic Chlorophyll-a values.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
