This dataset contains chemical and physical data collectedat University of Hawaii at Manoa from 2017-01-01 to 2019-12-31. These data include d13C, oxygen 16 to oxygen 18 ratio, pH, and water temperature. The instruments used to collect these data include Isotope-ratio Mass Spectrometer and Picarro L2130-I deltaD/delta18O Isotopic Water Analyzer. These data were collected by Joji Uchikawa and Richard Zeebe of University of Hawaii as part of the "Experimental study of CO2 hydration in seawater: Mechanism and kinetic isotope effects (CO2 Hydration Mechanism and KIEs)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-11-30.

Experimental data on kinetic C and O isotope fractionation of CO2 hydration

Dataset Description:
Acquisition Description:
We quasi-instantaneously precipitated BaCO 3 by bubbling CO 2 gas that was in full isotopic equilibrium with NaHCO 3 solution through highly concentrated BaCl 2 solutions buffered at alkaline pH. As the CO 2 gas entered the BaCl 2 solution through a fritted disk, a small fraction of it was transformed into HCO 3 − via diffusion and hydration across the thin-film of the bubbles. The resultant HCO 3 − immediately reacted with Ba 2 + in the solution and precipitated as BaCO 3 . By measuring δ 13 C and δ 18 O values of the BaCO 3 samples and experimental NaHCO 3 and H 2 O and applying oxygen mass-balance, we constrained kinetic C and O isotope effect associated with the hydration of CO 2 .

All carbonate samples (BaCO 3 and NaHCO 3 ) were analyzed at the University of California Santa Cruz for δ 13 C and δ 18 O, using a Thermo Finnigan MAT-253 dual-inlet isotope ratio monitoring mass spectrometer (irm-MS) coupled to a Kiel IV carbonate device. The samples were reacted with orthophosphoric acid and the resultant CO 2 gas was analyzed by the irm-MS. Note that all samples were treated as if they are calcite, which means that we did not apply the corrections to account for BaCO 3 -specific and NaHCO 3 -specific acid fractionation factor.

All H 2 O samples were analyzed for δ 18 O at the University of Hawaii on a PICARRO L2130- i isotope and gas concentration analyzer.
