Winners and losers under hydroxide-based ocean alkalinity enhancement in a Tasmanian plankton community. [PDF]

J Phycol
Abstract Ocean alkalinity enhancement (OAE) is an emerging carbon dioxide CO2 removal approach for climate change mitigation and can be implemented with various alkaline materials that convert dissolved CO2 into (bi)carbonates, enabling additional atmospheric CO2 removal. A key knowledge gap is how alkaline materials affect marine life.

Ocean Alkalinity Enhancement (OAE) does not cause cellular stress in a phytoplankton community of the sub-tropical Atlantic Ocean

Biogeosciences
Abstract. A natural plankton community from oligotrophic subtropical waters of the Atlantic near Gran Canaria, Spain, was subjected to varying degrees of ocean alkalinity enhancement (OAE) to assess the potential physiological effects, in the context of the application of ocean carbon dioxide removal (CDR) techniques.

The effect of ocean alkalinity enhancement on pelagic bacterial communities: focus points derived from a mesocosm experiment [PDF]

Frontiers in Microbiomes
Anthropogenic climate change caused by CO2 emissions forces humanity to reduce the usage of fossil fuels. Along with the task of emission reduction, societies face the task of removing excess CO2 from the atmosphere by using negative emission ...

Broaden Research on Ocean Alkalinity Enhancement to Better Characterize Social Impacts

Environmental Science & Technology, 2023
Ocean alkalinity enhancement (OAE) is being considered as a way of achieving large-scale removals of carbon dioxide from the atmosphere. Research on the risks and benefits of different OAE approaches is expanding apace, but it remains difficult to ...

Simulated Impact of Ocean Alkalinity Enhancement on Atmospheric CO2 Removal in the Bering Sea

Earth's Future, 2023
Ocean alkalinity enhancement (OAE) has the potential to mitigate ocean acidification (OA) and induce atmospheric carbon dioxide (CO2) removal (CDR). We evaluate the CDR and OA mitigation impacts of a sustained point‐source OAE of 1.67 × 1010 mol total ...

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.

Ocean Alkalinity Enhancement in Deep Water Formation Regions Under Low and High Emission Pathways [PDF]

Earth's Future
Ocean Alkalinity Enhancement (OAE) is an ocean‐based Carbon Dioxide Removal (CDR) method to mitigate climate change. Studies to characterize regional differences in OAE efficiencies and biogeochemical effects are still sparse.

Resilience of the gelatinous zooplankton species Oikopleura dioica to ocean alkalinity enhancement. [PDF]

PLoS ONE
Ocean alkalinity enhancement (OAE) through mineral dissolution is a promising marine carbon dioxide removal strategy because it increases the buffering capacity of seawater and thereby enhances passive storage of atmospheric CO2.
