Natural analogs to ocean alkalinity enhancement

, 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.

Assessing the technical aspects of ocean-alkalinity-enhancement approaches [PDF]

, 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 ...

Mesocosm experiments in ocean alkalinity enhancement research [PDF]

, 2023
An essential prerequisite for the implementation of ocean alkalinity enhancement (OAE) applications is their environmental safety. Only if it can be ensured that ecosystem health and ecosystem services are not at risk will the implementation of OAE move ...

Subsurface dissolution reduces the efficiency of mineral-based open-ocean alkalinity enhancement [PDF]

Biogeosciences
Carbon dioxide removal (CDR) from the atmosphere will likely be required to offset hard-to-abate emissions and limit global warming to well below 2 °C, in line with the Paris Agreement. Among proposed CDR strategies, ocean alkalinity enhancement (OAE) is

Impacts of simulated coastal ocean alkalinity enhancement on the seasonal carbon cycle in European waters under a low- and a high-emission scenario [PDF]

Earth System Dynamics
One potentially scalable method to remove CO2 from the air is ocean alkalinity enhancement (OAE), which works to lower the ocean's CO2 partial pressure (pCO2) and accelerate CO2 sequestration and durable storage.

Plankton food web structure and productivity under ocean alkalinity enhancement. [PDF]

Sci Adv
Ocean alkalinity enhancement (OAE) is a nature-based technology for CO2 removal and storage, but little is known about its environmental safety. We tested a CO2-equilibrated OAE deployment in a close-to-natural community using in situ mesocosms in the ...

Assessing the efficacy of river-based ocean alkalinity enhancement for carbon sequestration under high emission pathways [PDF]

Biogeosciences
Among various proposed geoengineering methods, ocean alkalinity enhancement (OAE) stands out as a unique solution. By mimicking natural weathering processes, OAE can simultaneously enhance oceanic carbon uptake and mitigate ocean acidification.

A numerical assessment of ocean alkalinity enhancement efficiency on a river-dominated continental shelf—a case study in the northern Gulf of Mexico

Environmental Research Letters
A robust high-resolution coupled hydrodynamic-biogeochemical model was applied to the northern Gulf of Mexico to assess the efficiency of river- and ocean-sourced ocean alkalinity enhancement (OAE).
