Modeling considerations for research on Ocean Alkalinity Enhancement (OAE) [PDF]

State of the Planet, 2023
Abstract. The deliberate increase of ocean alkalinity (referred to as Ocean Alkalinity Enhancement or OAE) has been proposed as a method for removing CO2 from the atmosphere. Before OAE can be implemented safely, efficiently, and at scale several research questions have to be addressed including: 1) which alkaline feedstocks are best suited and in what

Winners and losers under hydroxide‐based ocean alkalinity enhancement in a Tasmanian plankton community [PDF]

Journal of Phycology
Abstract Ocean alkalinity enhancement (OAE) is an emerging carbon dioxide CO2 removal approach for climate change mitigation and can be implemented with various alkaline materials that convert dissolved CO2 into (bi)carbonates, enabling additional atmospheric CO2 removal. A key knowledge gap is how alkaline materials affect marine life.

The additionality problem of ocean alkalinity enhancement [PDF]

Biogeosciences
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 ...

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.

Microbial ecosystem responses to alkalinity enhancement in the North Atlantic Subtropical Gyre [PDF]

Frontiers in Climate, 2022
In addition to reducing carbon dioxide (CO2) emissions, actively removing CO2 from the atmosphere is widely considered necessary to keep global warming well below 2°C.

Ocean Alkalinity Enhancement (OAE) does not cause cellular stress in a phytoplankton community of the sub-tropical Atlantic Ocean [PDF]

Biogeosciences
Abstract. A natural plankton community from oligotrophic subtropical waters of the Atlantic near Gran Canaria, Spain, was subjected to varying degrees of ocean alkalinity enhancement (OAE) to assess the potential physiological effects, in the context of the application of ocean carbon dioxide removal (CDR) techniques.

On the emission-path dependency of the efficiency of ocean alkalinity enhancement [PDF]

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 ...
