Resilience to Alkalinity Perturbations Reveals Ecosystem Stability under Ocean Alkalinity Enhancement

Ocean-Land-Atmosphere Research
Ocean alkalinity enhancement (OAE) is a leading climate mitigation strategy for atmospheric carbon dioxide removal, with theoretical potential to sequester gigatons of CO2 annually while counteracting ocean acidification.

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).

A comparison of metrics for CO ₂ uptake efficiency of regional ocean alkalinity enhancement in an Earth system model

. Ocean Alkalinity Enhancement (OAE) is a method proposed for ocean-based Carbon-Dioxide Removal and describes the sequestration of CO2 from the atmosphere through a deliberate increase in alkalinity in the ocean.

KOSMOS 2021 Gran Canaria mesocosm study on ocean alkalinity enhancement: phytoplankton metabolic rates

Ocean Alkalinity Enhancement (OAE) could augment long-term carbon storage and mitigate ocean acidification by increasing the bicarbonate ion concentration in ocean water. However, the side effects and/or potential co-benefits of OAE on natural planktonic
