KOSMOS 2022 Bergen mesocosm study on ocean alkalinity enhancement: phytoplankton metabolic rates [PDF]

Ocean alkalinity enhancement (OAE) is a marine carbon dioxide removal (mCDR) with the potential to remove atmospheric CO2 and increase the ocean's buffering capacity. Thus, it may aid in mitigating global warming and ocean acidification. Depending on the

Assessing the impact of CO2-equilibrated ocean alkalinity enhancement on microbial metabolic rates in an oligotrophic system [PDF]

Ocean alkalinity enhancement (OAE) is a negative emissions technology (NET) that shows significant potential for climate change mitigation. By increasing the bicarbonate ion concentration in ocean water, OAE could enhance long-term carbon storage and ...

Evaluating rainbowing for ocean alkalinity enhancement [PDF]

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.

Tackling the technological, environmental, legal, and economic challenges of ocean alkalinity enhancement: A case study from the Baltic sea

iScience
Summary: Ocean alkalinity enhancement (OAE) is a possible climate mitigation technology that can remove CO2 from the atmosphere. Here, we studied the feasibility of OAE in a case study using serpentinite gangue and examined the carbon dioxide removal ...

Assessing the effects of ocean alkalinity enhancement on marine protozoa: physiological dynamics and transcriptomic responses

Applied and Environmental Microbiology
Ocean alkalinity enhancement (OAE) is proposed as a potential tool to remove atmospheric CO2 and mitigate climate change. However, the effects of OAE on marine protozoa remain poorly understood.

Regulation of Ocean Alkalinity Enhancement in Washington State [PDF]

This paper focuses on one commonly-discussed ocean carbon dioxide removal approach, ocean alkalinity enhancement (“OAE”), which involves adding alkaline substances to ocean waters in order to increase their ability to uptake carbon dioxide from the ...

Ocean liming effect on a North Atlantic microbial community: changes in composition and rates

Frontiers in Marine Science
The ongoing rise in atmospheric CO2 levels and the consequent global warming make it increasingly difficult to maintain the global temperature within the 1.5 - 2°C target set by the Paris Agreement. Therefore, strategies to remove carbon dioxide from the

Assessing the effectiveness of ocean alkalinity enhancement on carbon sequestration and ocean acidification

FACETS
As atmospheric carbon dioxide (CO2) levels continue to rise, increasing attention is focussed mitigation techniques that could enhance the natural draw down of CO2. One such mitigative intervention is ocean alkalinity enhancement (OAE).
