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.

Maximizing the Detectability of Ocean Alkalinity Enhancement (OAE) While Minimizing Its Exposure Risks: Insights From a Numerical Study

Earth's Future
Ocean alkalinity enhancement (OAE) can potentially remove gigatons of CO2 from the atmosphere for durable storage in the ocean. Before implementing OAE at climate‐relevant scales, questions about its safety and verifiability must be addressed ...

Deglacial Pulse of Neutralized Carbon From the Pacific Seafloor: A Natural Analog for Ocean Alkalinity Enhancement?

Geophysical Research Letters
The ocean carbon reservoir controls atmospheric carbon dioxide (CO2) on millennial timescales. Radiocarbon (14C) anomalies in eastern North Pacific sediments suggest a significant release of geologic 14C‐free carbon at the end of the last ice age but ...

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).
