Aragonite precipitation rates from seawater of variable pH, saturation state, biomolecule composition and temperature

Precipitations were conducted using a pH stat titrator using the constant composition technique between August 2020 and April 2022. Aragonite precipitation rates are estimated from the rate of titrant dosing. pH and DIC are used to estimate the seawater aragonite saturation state of each precipitation and, on occasion, the [HCO3-] and [CO32-]. Data were collected to determine how changes in the calcification fluids of calcareous organisms affect aragonite precipitation. Data were collected by Cristina Castillo Alvarez and interpreted by Cristina Castillo Alvarez, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Kröger and Matthieu Clog.

Statement: Artificial seawater was manipulated to alter pH and dissolved inorganic carbon concentration. If used, amino acids were added to generate the final reported seawater concentration. An aragonite seed was added as a surface for aragonite growth. A pH stat titrator monitored pH and dosed titrants (Na2CO3 and CaCl2) to replace the Ca2+ and CO32- consumed during aragonite formation. At the end, the solid was collected by filtration, rinsed with water and ethanol, dried at 40°C and stored.
