eReefs GBR1 Diuron Dispersal

The eReefs GBR1 Diuron Dispersal dataset from the Australian Ocean Data Network models the transport of the pesticide diuron in the Great Barrier Reef marine environment. It uses a 1 km resolution hydrodynamic model forced by wind, tides, and river inputs from 16 catchments to simulate hourly diuron concentrations from January 2016 to July 2018. The model incorporates a determined diuron half-life of 40 days and compares simulated distributions with observations from 11 monitoring sites.

Use Cases

• Modeling pesticide fate and transport in coastal waters based on the described hydrodynamic and advection schemes.
• Assessing compliance with water quality guidelines for diuron based on simulated concentration distributions.
• Analyzing the influence of specific river plumes (e.g., Murray, Mossman) on marine pollution based on the use of unique conservative tracers.
• Studying the seasonal and interannual variability of pollutant loads from 2016 to 2018 based on the simulation time range.

Strengths

• Simulation spans a 2.5-year period from January 2016 to July 2018.
• Model incorporates a calibrated diuron half-life of 40 days, validated against 11 monitoring sites.
• Uses high-resolution (1 km) nested modelling with realistic river plume dynamics from 16 catchments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data files are listed as PNG and HTML, suggesting the primary outputs may be visualizations or reports rather than raw model data tables.
• Row count and data size are unknown, which may limit suitability assessment for quantitative analysis.
