World Resources Institute: Leveraging the Ocean's Carbon Removal Potential

"As the need for climate action becomes more urgent, the ocean is gaining attention as a potential part of the solution. Approaches like investing in offshore energy production, conserving coastal ecosystems and increasing consumption of sustainable ocean-based protein offer opportunities to reduce emissions. In addition to these opportunities, a range of ocean-based carbon removal approaches could help capture and store billion of tons of carbon."

Burns, Wil; Corbett, Charles R. (2020): Antacids for the Sea? Artificial Ocean Alkalinization and Climate Change

Burns, Wil; Corbett, Charles R. (2020): Antacids for the Sea? Artificial Ocean Alkalinization and Climate Change. In One Earth 3 (2), pp. 154–156. DOI: 10.1016/j.oneear.2020.07.016.

"There is increasing urgency for large-scale deployment of carbon-removal approaches to help avoid passing critical climatic thresholds. Given the severe risks of many terrestrial methods at extremely large scales, there is a compelling need to also assess the potential of marine negative-emissions technologies, such as artificial ocean alkalinization."

Gagern, Antonius; et al. (2019): Ocean Alkalinity Enhancement. Current state of knowledge and potential role of philanthropy

Gagern, Antonius; Rau, Greg; Iglesias-Rodriguez, Debora; Renforth, Phil; Burns, Wil; Graffy, Elisabeth (September 9th, 2019 Meeting Proceedings): Ocean Alkalinity Enhancement. Current state of knowledge and potential role of philanthropy. Half Moon Bay, California.

"This document merges a thorough literature review with insights gained during the convening. In the last decade, specific aspects of OAE have received some attention in the specialized CDR literature (such as in AGU100 journals) but significant knowledge gaps remain. This document makes an attempt at discussing current knowledge and knowledge gaps relating to the local and global application of OAE and to provide recommendations to the broader philanthropic community that is considering supporting the advancement of the field."

CEA Primer on Global Ocean Threats

"In 2019, CEA was hired to convene a group of leading scientists and philanthropic funders to discuss the current state of knowledge on ocean alkalinity enhancement (OAE), a potentially promising carbon dioxide removal strategy. In preparation of the meeting, CEA produced a comprehensive primer highlighting the technological approaches and open questions and reviewed the known and unknown potential ecosystem implications of OAE. After a productive convening in September 2019, CEA produced a proceedings document, co-authored by attending experts. The proceedings document includes a summary of philanthropic investment opportunities discussed during the meeting."
