δ65Cu isotopic fractionation in coral tissue: A biomarker of holobiont photophysiology following volcanic ash exposure (Original data)

This original data contains the results of physiological measurements (photosynhtetic parameters, photosynthesis and respiration rates) on individual Stylophora pistillata coral nubbins, and chemical analysis results of the minor and trace element composition, including Fe, Cu and Zn isotopic composition of coral tissue, its symbionts, and of unaltered and pristine volcanic ash.
