Growth response of Emiliania huxleyi to ocean alkalinity enhancement [PDF]

Biogeosciences
The urgent necessity of reducing greenhouse gas emissions is coupled with a pressing need for widespread implementation of carbon dioxide removal (CDR) techniques to limit the increase in mean global temperature to levels below 2 °C compared to pre ...

Natural analogs to ocean alkalinity enhancement

State of the Planet, 2023
Abstract. Ocean alkalinity enhancement (OAE) research can be supplemented by studying the natural alkalinity cycle. In this chapter, we introduce the concept of natural analogs to ocean alkalinity enhancement. We describe Earth system processes relevant to OAE deployment and its measurement, reporting, and verification.

A biogeochemical model of mineral-based ocean alkalinity enhancement: impacts on the biological pump and ocean carbon uptake

Environmental Research Letters, 2023
Minimizing anthropogenic climate disruption in the coming century will likely require carbon dioxide removal (CDR) from Earth’s atmosphere in addition to deep and rapid cuts to greenhouse gas emissions.

Monitoring, Reporting, and Verification for Ocean Alkalinity Enhancement

State of the Planet, 2023
Abstract. Monitoring, Reporting, and Verification (MRV) refers to the multistep process of monitoring the amount of greenhouse gas removed by a Carbon Dioxide Removal (CDR) activity and reporting the results of the monitoring to a third party. The third party then verifies the reporting so the results.

Technology Development and Future Directions of Ocean Alkalinity Enhancement

Haiyang Kaifa yu guanli, 2023
Since the industrial revolution, nearly one-third of anthropogenic carbon dioxide emissions have been absorbed by the ocean which has a huge potential for negative emissions.

Novel field trial for ocean alkalinity enhancement using electrochemically derived aqueous alkalinity

Frontiers in Environmental Engineering
Ocean alkalinity enhancement is a proposed method of marine carbon dioxide removal that enhances the ocean’s uptake of atmospheric carbon dioxide (CO2) and converts it to dissolved bicarbonate for long-term ocean storage.

On the emission-path dependency of the efficiency of ocean alkalinity enhancement

Environmental Research Letters
Ocean alkalinity enhancement (OAE) deliberately modifies the chemistry of the surface ocean to enhance the uptake of atmospheric CO _2 . The chemical efficiency of OAE (the amount of CO _2 sequestered per unit of alkalinity added) depends, among other ...

Effects of ocean alkalinity enhancement on plankton in the Equatorial Pacific

Communications Earth & Environment
Ocean alkalinity enhancement is a potential strategy for gigatonne-scale atmospheric carbon dioxide removal. It uses alkaline substances to convert seawater carbon dioxide into (bi)carbonate, enabling uptake of additional carbon dioxide from the ...
