Coral Physiology Data on CO2 and Temperature Effects, 2003

A 2003 study by Stéphanie Reynaud investigated the interacting effects of CO2 partial pressure and temperature on the coral Stylophora pistillata. Cuttings were exposed to two temperatures and two pCO2 levels for five weeks, measuring impacts on chlorophyll content, cell density, photosynthesis, respiration, and calcification. Calcification decreased by 50% when both temperature and pCO2 were elevated, a finding that challenges some prior literature.

Use Cases

• Modeling the interactive effects of pCO2 and temperature on coral calcification rates.
• Analyzing the relationship between chlorophyll a content and high-temperature-high-pCO2 conditions.
• Investigating the variability in reported marine calcification responses to CO2 by accounting for temperature.
• Training predictive models for coral health under projected climate scenarios.

Strengths

• Experimental design with controlled pCO2 levels (ca. 460 or 760 µatm) and temperatures (25°C or 28°C).
• Reports specific quantitative results, such as a 50% decrease in calcification under elevated conditions and cell density comparisons (1.7 vs. 1.4).
• Study duration of 5 weeks provides a controlled temporal frame for physiological measurements.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred from the paper.
• Data may reflect the specific experimental conditions and single coral species (Stylophora pistillata), limiting generalizability.
• Last update date and original data file formats are unknown.
