Why we care Ocean alkalinity enhancement has the potential to capture carbon and mitigate ocean acidification. While ocean alkalinity enhancement is a promising approach for removing carbon from the atmosphere, there are important questions about its impacts on the marine environment. A strategic roadmap identifying and addressing concerns about deployment of ocean alkalinity enhancement is
Assessing the chemical and biological implications of alkalinity enhancement using carbonate salts from captured carbon dioxide to mitigate ocean acidification and enable mCDR
Why we care Energy, manufacturing and deployment costs are critical to the viability of any carbon dioxide removal approach. This research project focuses on a new strategy that promises low energy burden and low manufacturing costs to capture carbon and achieve ocean alkalinity enhancement, essential features for scaling any future efforts of this technology to
Assessing the laboratory and field responses of diatoms and coccolithophores to ocean alkalinity enhancement
Why we care Ocean alkalinity enhancement relies on modifying the acid-base properties of seawater to remove carbon dioxide, however the effect of this strategy on primary productivity, cell physiology, and carbon export remain unknown. These impacts are not only potential ecosystem effects, but may influence the efficiency of carbon dioxide removal. This research focuses on
Determining the Influence of Ocean Alkalinity Enhancement on Foraminifera Calcification, Distribution, and Calcium carbonate Production
Why we care Foraminifera, or forams, are single-celled organisms that produce calcium carbonate shells and play a crucial role in the ocean’s carbon cycle. Ocean alkalinity enhancement aims to increase the ocean’s ability to absorb carbon dioxide by enhancing its buffering capacity. However, the impact of the addition of alkalinity on foraminifera is not well
Assessing efficacy of electrochemical ocean alkalinity enhancement at an existing outfall using tracer release experiments and oceanographic models
Why we care Adding alkalinity to the ocean may provide a safe and effective approach to removing carbon dioxide from the atmosphere. Assessing the efficacy and efficiency of ocean alkalinity enhancement are essential steps to ensuring that this method of carbon dioxide removal can contribute to mitigating climate change and ocean acidification. What we will
