One challenge is the potential for secondary precipitation to occur, which can lead to a loss of added alkalinity and stored CO2. Another challenge is the need to understand the mechanisms underlying the biogeochemical responses to ocean alkalinity enhancement. A third challenge is the requirement for careful sampling and analysis to minimize contamination and ensure accurate results.

Further research is needed to understand the long-term effects of Ocean Alkalinity Enhancement on marine ecosystems. Studies should investigate the impacts of Ocean Alkalinity Enhancement on different marine ecosystems and regions. Research should focus on developing strategies for ecologically safe deployment of Ocean Alkalinity Enhancement.
