Experimental data from the Australian Ocean Data Network quantifies the chronic effects and persistence of agricultural herbicides on seagrass and corals in the Great Barrier Reef. The project, active from 2011 to 2014, involved controlled laboratory and outdoor tank experiments simulating flood plume conditions. It measured toxic thresholds and herbicide half-lives under various stressors like temperature and low light.
Use Cases
- Modeling herbicide persistence (half-lives) in tropical coastal waters based on experimental conditions described.
- Assessing cumulative toxic effects on corals and seagrass under combined stressors like temperature and low salinity mentioned in the description.
- Evaluating the toxicity of herbicide breakdown products from diuron, atrazine, hexazinone, and tebuthiuron as outlined in the project goals.
Strengths
- Data is associated with a defined multi-year research project (2011-2014) from the Australian Ocean Data Network.
- Experimental design targets specific herbicides (diuron, atrazine, hexazinone, tebuthiuron) and environmental stressors relevant to the Great Barrier Reef.
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 bias inherent to data_gov_au, focusing on the Great Barrier Reef.
