[1] The feasibility of enhancing the absorption of CO2 from the atmosphere by adding calcium carbonate (CaCO3) powder to the ocean and of partially reversing the acidification of the ocean and the decrease in calcite supersaturation resulting from the absorption of anthropogenic CO2 is investigated. CaCO3 could be added to the surface layer in regions where the depth of the boundary between supersaturated and unsaturated water is relatively shallow (250–500 m) and where the upwelling velocity… Expand
Assessing the potential of calcium-based artificial ocean alkalinization to mitigate rising atmospheric CO2 and ocean acidification
Enhancement of ocean alkalinity using calcium compounds, e.g., lime has been proposed to mitigate further increase of atmospheric CO2 and ocean acidification due to anthropogenic CO2 emissions.Expand

If solar radiation management were to be the main policy response to counteract global warming, ocean acidification would continue to be driven by increases in atmospheric CO2, although with additional temperature-related effects on CO2 and CaCO3 solubility and terrestrial carbon sequestration.

Engineering challenges of ocean liming
The relationship between the level of atmospheric CO2 (carbon dioxide) and the impacts of climate change is uncertain, but a safe concentration may be surpassed this century. Therefore, it isExpand

Geoengineering impact of open ocean dissolution of olivine on atmospheric CO2, surface ocean pH and marine biology
Ongoing global warming induced by anthropogenic emissions has opened the debate as to whether geoengineering is a 'quick fix' option. Here we analyse the intended and unintended effects of oneExpand
Geoengineering potential of artificially enhanced silicate weathering of olivine
The potential of a specific geoengineering technique, carbon sequestration by artificially enhanced silicate weathering via the dissolution of olivine, is investigated and the consequences of sequestration rates of 1–5 Pg of C per year for the 21st century are calculated. Expand
Assessing ocean alkalinity for carbon sequestration
Over the coming century humanity may need to find reservoirs to store several trillions of tons of carbon dioxide (CO2) emitted from fossil fuel combustion, which would otherwise cause dangerousExpand

Electrochemical splitting of calcium carbonate is explored as a means of forming dissolve hydroxides for absorbing, neutralizing, and storing carbon dioxide, and for restoring, preserving, or enhancing ocean calcification. Expand


CO2 Air–Sea Exchange due to Calcium Carbonate and Organic Matter Storage, and its Implications for the Global Carbon Cycle
Release of CO2 from surface ocean water owing to precipitation of CaCO3 and the imbalance between biological production of organic matter and its respiration, and their net removal from surface waterExpand
Accelerating carbonate dissolution to sequester carbon dioxide in the ocean: Geochemical implications
Various methods have been proposed for mitigating release of anthropogenic CO2 to the atmosphere, including deep-sea injection of CO2 captured from fossil-fuel fired power plants. Here, we use aExpand
Enhanced carbonate dissolution : a means of sequestering waste CO2 as ocean bicarbonate
Abstract The reaction of a mineral carbonate, such as limestone, with water and CO 2 to form bicarbonate in solution, is explored as a CO 2 mitigation strategy. Initial cost estimates for such aExpand
Reduced calcification of marine plankton in response to increased atmospheric CO2
It is suggested that the progressive increase in atmospheric CO2 concentrations may slow down the production of calcium carbonate in the surface ocean, as the process of calcification releases CO2 to the atmosphere. Expand
Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.
