We present a novel determination of the dissolution kinetics of inorganic calcite in seawater. We dissolved 13C-labeled calcite in unlabeled seawater, and traced the evolving δ13C composition […]

Near-equilibrium calcite dissolution in seawater contributes significantly to the regulation of atmospheric CO2 on 1,000-y timescales. Despite many studies on far-from-equilibrium dissolution, […]
This study provides laboratory data of calcite dissolution rate as a function of seawater undersaturation state (1 − Ω) under variable pressure. 13C-labeled calcite was dissolved in […]
Knowledge of the mechanism of calcite dissolution in seawater is a critical component of our understanding of the changing global carbon budget. Towards this goal, […]
Ocean acidification from fossil fuel burning is lowering the mean global ocean saturation state (Ω = Ca2+CO32−Ksp′), thus increasing the thermodynamic driving force for calcium […]
We present the first examination of calcite dissolution in seawater using Atomic Force Microscopy (AFM). We quantify step retreat velocity and etch pit density to compare […]
Abstract The dissolution of CaCO3 minerals in the ocean is a fundamental part of the marine alkalinity and carbon cycles. While […]
Carbonic anhydrase (CA) has been shown to promote calcite dissolution (Liu, 2001, https://doi.org/10.1111/j.1755-6724.2001.tb00531.x; Subhas et al., 2017, https://doi.org/10.1073/pnas.1703604114), and understanding the catalytic […]
