Renforth, P.; Campbell, J. S. (2021): The role of soils in the regulation of ocean acidification. In Philosophical transactions of the Royal Society of London. Series B, Biological sciences 376 (1834), p. 20200174. DOI: 10.1098/rstb.2020.0174.

"Increasing the alkalinity levels in the ocean through enhanced weathering could help to ameliorate the effects of ocean acidification in two ways. First, enhanced weathering would slightly elevate the pH of drainage waters, and the receiving coastal waters. The elevated pH would result in an increase in carbonate mineral saturation states, and a partial reversal in the effects of elevated CO2. Second, the increase in alkalinity would help to replenish the ocean's buffering capacity by maintaining the ‘Revelle Factor’, making the oceans more resilient to further CO2 emissions. However, there is limited research on the downstream and oceanic impacts of enhanced weathering on which to base deployment decisions."
