Great Barrier Reef Biogeochemical Model Output at 4km Resolution

2011 to 2018 biogeochemical model data for the Great Barrier Reef at 4-kilometer resolution. The dataset, now superseded, was produced by the Australian Ocean Data Network using a model forced by hydrodynamic data and varying catchment source inputs. It was archived by custodians in April 2024.

Use Cases

• Analyze temporal trends in modeled biogeochemical parameters like chlorophyll or nutrients across the 2011-2018 period.
• Validate satellite-derived ocean color data against the model's 4km-resolution spatial output fields.
• Assess the impact of different catchment forcing sources (P2R, Empirical, Furnas) on simulated reef water quality.
• Correlate hydrodynamic model forcing data with biogeochemical state variables to study physical-biological couplings.

Strengths

• Model output spans over 7 years from 2011 to 2018.
• Provides high-resolution spatial data at a 4km grid scale.
• Documents specific forcing methodologies used for different time periods within the simulation.

Limitations

• Dataset is explicitly superseded and not actively maintained or hosted.
• Exact data volume, row count, and available variables are unknown.
• Access requires a manual request to custodians, indicating low availability.
