Field experiments in ocean alkalinity enhancement research

Tyler Cyronak, Rebecca Albright, and Lennart Bach

Abstract. This chapter focuses on considerations for conducting open-system field experiments in the context of ocean alkalinity enhancement (OAE) research. By conducting experiments in real-world marine systems, researchers can gain valuable insights into ecological dynamics, biogeochemical cycles, and the safety, efficacy, and scalability of OAE techniques under natural conditions. However, logistical constraints and complex natural dynamics pose challenges for successful field trials. To date, only a limited number of OAE field studies have been conducted, and guidelines for such experiments are still evolving. Due to the fast pace of carbon dioxide removal (CDR) research and development, we advocate for openly sharing knowledge and lessons learned as quickly as possible within the broader OAE community and beyond. Considering the potential ecological and societal consequences of field experiments, active engagement with the public and other stakeholders is essential. Collaboration, data sharing, and transdisciplinary teams are vital for maximizing the return on investment during field trials. The outcomes of early field deployments are likely to shape the future of OAE, emphasizing the need for transparent and open scientific practices.

Short summary
Ocean alkalinity enhancement (OAE) is a marine carbon dioxide removal (CDR) approach. Publicly funded research projects have begun, and philanthropic funding and start-ups are collectively pushing the field forward. This rapid progress in research activities has created an urgent need to learn if and how OAE can work at scale. This chapter of the Best Practices Guide to OAE research focuses on field experiments.
