Natural analogs to ocean alkalinity enhancement

State of the Planet, 2023
<jats:p>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.

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

Monitoring, reporting, and verification for ocean alkalinity enhancement

State of the Planet, 2023
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

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
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 ...

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.

Particle fluxes by subtropical pelagic communities under ocean alkalinity enhancement [PDF]

Biogeosciences
Ocean alkalinity enhancement (OAE) has been proposed as a carbon dioxide removal technology (CDR), allowing for long-term storage of carbon dioxide in the ocean.

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 ...

On the emission-path dependency of the efficiency of ocean alkalinity enhancement

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 ...

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 ...
