The full width half maxima (FWHM) of the ν1 peak in the aragonite spectrum by Raman spectroscopy of coral skeletal aragonite from 7 genotypes of massive Porites spp. corals (G1 to G7) cultured at varying seawater pCO2 and temperature.

FWHM of coral skeletal samples from 7 coral genotypes cultured in an aquarium at seawater pCO2 of 180, 260, 400 and 750 µatm and at seawater temperature of 25 and 28 degrees C (39 samples total). Data were collected to determine how environmental conditions influence disorder in the aragonite lattice of coral skeletons. Data were collected between August 2020 and December 2022 by Phoebe Ross, Celeste Kellock, Cristina Castillo Alvarez and Nicola Allison and interpreted by Phoebe Ross, Celeste Kellock, Cristina Castillo Alvarez, David Evans, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Kröger, and Matthieu Clog.
