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]

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 [PDF]

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.

Monitoring, Reporting, and Verification for Ocean Alkalinity Enhancement [PDF]

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.

Ocean alkalinity enhancement in an estuary

Frontiers in Climate
A 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

Evaluating rainbowing for ocean alkalinity enhancement

Environmental Research Communications
Ocean 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.

Assessing the technical aspects of ocean-alkalinity-enhancement approaches [PDF]

State of the Planet, 2023
Abstract. Ocean alkalinity enhancement (OAE) is an emerging strategy that aims to mitigate climate change by increasing the alkalinity of seawater. This approach involves increasing the alkalinity of the ocean to enhance its capacity to absorb and store carbon dioxide (CO2) from the atmosphere. This chapter presents an overview of the technical aspects

Technology Development and Future Directions of Ocean Alkalinity Enhancement [PDF]

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.

Effects of ocean alkalinity enhancement on plankton in the Equatorial Pacific [PDF]

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 ...

Technical note: Ocean Alkalinity Enhancement Pelagic Impact Intercomparison Project (OAEPIIP) [PDF]

Biogeosciences
Ocean alkalinity enhancement (OAE) aims to transfer carbon dioxide (CO2) from the atmosphere to the ocean by increasing the capacity of seawater to store CO2.
