Ocean alkalinity enhancement in an estuary [PDF]
Frontiers in ClimateA high-resolution numerical ocean model is used to assess ocean alkalinity enhancement (OAE) in the San Francisco Bay (SFB) estuary. A novel tracer-based approach is introduced to simulate alkalinity release and the subsequent CO2 ingassing. The model is

The additionality problem of ocean alkalinity enhancement [PDF]
Biogeosciences, 2023 Ocean alkalinity enhancement (OAE) is an emerging approach for atmospheric carbon dioxide removal (CDR). The net climatic benefit of OAE depends on how much it can increase CO2 sequestration relative to a baseline state without OAE.

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

On the emission-path dependency of the efficiency of ocean alkalinity enhancement [PDF]
Environmental Research LettersOcean 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 ...

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.

Evaluating rainbowing for ocean alkalinity enhancement
Environmental Research CommunicationsOcean Alkalinity Enhancement (OAE) is a technique proposed to address ocean acidification and global warming. This study examines rainbowing (i.e. water jets pumped into the air from ships) for the slaked lime slurry distribution.

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.

Stability of alkalinity in ocean alkalinity enhancement (OAE) approaches – consequences for durability of CO2 storage [PDF]
Biogeosciences, 2023 According to modelling studies, ocean alkalinity enhancement (OAE) is one of the proposed carbon dioxide removal (CDR) approaches with large potential, with the beneficial side effect of counteracting ocean acidification.

Regional ocean dynamics regulate the efficiency of ocean alkalinity enhancement
Frontiers in ClimateOcean alkalinity enhancement (OAE) is a promising marine carbon dioxide removal (mCDR) method that aims to reduce atmospheric CO2 by increasing the ocean's storage capacity.
