The full width half maxima (FWHM) of the ν1 peak in the aragonite spectrum by Raman spectroscopy of aragonite precipitated in vitro over varying temperature and seawater omega(aragonite)

FWHM of 19 aragonite samples precipitated from seawater, using a pH stat titrator using the constant composition technique between August 2020 and December 2022. Aragonite precipitation rates are estimated from the rate of titrant dosing. Data were collected to determine how changes in the calcification fluids of calcareous organisms affect aragonite structure. Data were collected by Cristina Castillo Alvarez and Nicola Allison and interpreted by Cristina Castillo Alvarez, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Kröger and Matthieu Clog.
