Acropora Millepora Coral Growth Under pH and Light Stress, 16-Day Experiment

One data file from a 16-day aquarium experiment manipulating pH and light levels on the stony coral Acropora millepora. The study, conducted at the Australian Institute of Marine Science in 2012, measured growth, photosynthesis, calcification, and pigment content to test for combined stressor effects. Data includes measurements from 12 experimental aquaria with four treatments and three replicate tanks each.

Use Cases

• Modeling coral growth rates based on manipulated pH and light levels described in the experiment.
• Analyzing the interactive effects of multiple stressors on coral photosynthesis and calcification metrics.
• Comparing physiological responses (pigment content, buoyant weight) between control and stress treatment groups.

Strengths

• Data originates from a controlled 16-day manipulative experiment with specific pH (427/1073 µatm pCO2) and light (35/150 PAR) levels.
• Includes three biological replicates per treatment across four distinct experimental conditions.
• Measurements cover multiple physiological responses: growth, photosynthesis, calcification, and pigment content.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single 16-day experiment in 2012; temporal and geographic scope is limited.
