Superseded eReefs Biogeochemical and Sediments Model for Great Barrier Reef

A collection of the superseded eReefs GBR4 biogeochemical and sediments model data version 926, which was removed from the NCI fx3 project and THREDDS server in April 2024. It is based on a 4 km resolution hydrodynamic model for physical properties, a sediment transport model, and a biogeochemical model for water quality and nutrient cycling.

Use Cases

• Analyze nutrient cycling patterns using the biogeochemical model outputs for water column and benthic production.
• Model the fate of suspended fine sediments across the Great Barrier Reef using the integrated sediment transport model.
• Study water quality dynamics by leveraging the spectrally resolved light model and wave-forced resuspension rates.
• Compare superseded model outputs (version 926) with newer versions for validation and historical analysis of biogeochemical processes.

Strengths

• Model integrates hydrodynamic, sediment transport, and biogeochemical components for a comprehensive system view.
• Provides 4 km spatial resolution data for the Great Barrier Reef region.
• Includes a spectrally resolved light model and is forced by a wave model for calculating resuspension.

Limitations

• Dataset is explicitly marked as superseded and archived, indicating it is not the current operational version.
• Access is restricted and must be arranged on request with the custodians, limiting immediate availability.
• Specific data volume, row count, and column structure are unknown from the provided input.
