The Sensitivity of the Marine Carbonate System to Regional Ocean Alkalinity Enhancement [PDF]

Frontiers in Climate, 2021
Ocean Alkalinity Enhancement (OAE) simultaneously mitigates atmospheric concentrations of CO2 and ocean acidification; however, no previous studies have investigated the response of the non-linear marine carbonate system sensitivity to alkalinity ...

Alkalinity enhancement with sodium hydroxide in coastal ocean waters [PDF]

Scientific Reports
Carbon Dioxide Removal (CDR) is increasingly recognised as essential for achieving net zero emissions to limit the impacts of climate change. Ocean Alkalinity Enhancement (OAE) presents a potentially scalable marine CDR (mCDR) technique.

The additionality problem of ocean alkalinity enhancement [PDF]

Biogeosciences, 2023
Ocean alkalinity enhancement (OAE) is an emerging approach for atmospheric carbon dioxide removal (CDR). The net climatic benefit of OAE depends on how much it can increase CO2 sequestration relative to a baseline state without OAE.

High frequency in situ total alkalinity measurement for monitoring ocean alkalinity enhancement field trials [PDF]

Communications Engineering
Ocean alkalinity enhancement increases seawater alkalinity to boost carbon dioxide uptake. We report the first field deployment of an autonomous Lab-on-a-Chip total alkalinity analyzer during an ocean alkalinity enhancement trial using magnesium ...

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

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.

Stability of alkalinity in ocean alkalinity enhancement (OAE) approaches – consequences for durability of CO₂ storage [PDF]

Biogeosciences, 2023
According to modelling studies, ocean alkalinity enhancement (OAE) is one of the proposed carbon dioxide removal (CDR) approaches with large potential, with the beneficial side effect of counteracting ocean acidification.

Resilience of Phytoplankton and Microzooplankton Communities under Ocean Alkalinity Enhancement in the Oligotrophic Ocean. [PDF]

Environ Sci Technol
Ocean alkalinity enhancement (OAE) is currently discussed as a potential negative emission technology to sequester atmospheric carbon dioxide in seawater. Yet, its potential risks or cobenefits for marine ecosystems are still mostly unknown, thus hampering its evaluation for large-scale application.

Regional ocean dynamics regulate the efficiency of ocean alkalinity enhancement

Frontiers in Climate
Ocean alkalinity enhancement (OAE) is a promising marine carbon dioxide removal (mCDR) method that aims to reduce atmospheric CO2 by increasing the ocean's storage capacity.
