An essential prerequisite for the implementation of ocean alkalinity enhancement (OAE) applications is their environmental safety. In this context mesocosm experiments represent a highly valuable tool in determining the safe operating space of OAE applications. This chapter outlines strengths and weaknesses of mesocosm approaches, illustrates mesocosm facilities and suitable experimental designs presently employed in OAE research, describes critical steps in mesocosm operation, and discusses possible approaches for alkalinity manipulation and monitoring.
