DOI: 10.1016/j.gca.2019.09.037
Abstract: Abstract Prediction of the neutralization of anthropogenic CO2 in the oceans and the interpretation of the calcite record preserved in deep-sea sediments requires the use of the correct kinetics for calcite dissolution. Dissolution rate information… read more here.

DOI: 10.1080/03650340.2019.1628344
Abstract: ABSTRACT We studied (i) the pH buffer capacity (pHBC) of calcareous soils varied widely in calcite and texture, (ii) the contribution of soil properties to pHBC and (iii) the significance of using a model based… read more here.
