Experimental data from a 15-day study simulating combined climate change and diuron contamination effects on the calcareous green algae Halimeda opuntia. The dataset includes photosynthetic efficiency and oxygen production measurements from 54 experimental chambers across three climate scenarios and six diuron concentrations. Data was collected by the Australian Institute of Marine Science (AIMS) as part of the NESP TWQ 2.1.6 project.
Use Cases
- Modeling the combined effects of temperature, pCO2, and herbicide concentration on algal photosynthetic efficiency based on the described experimental design.
- Assessing climate change impacts on contaminant toxicity thresholds for marine organisms using the simulated 2050 and 2100 scenarios.
- Evaluating species fitness under multiple stressors using the photochemistry parameters and oxygen production endpoints mentioned in the description.
Strengths
- Data is derived from a controlled 15-day experiment with a clear factorial design of three climate scenarios and six diuron concentrations.
- Includes two complementary physiological endpoints: photosynthetic efficiency via PAM fluorometry and direct oxygen production measurements.
- Sample size was increased for the ambient control condition, providing a stronger reference baseline.
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 experimental bias inherent to the mesocosm setup described.
