Short summary
This chapter summarizes some key general considerations for experimental research methods  and compares the strengths and weaknesses of the different approaches. It also considers best practices relevant to ocean alkalinization enhancement, such as the need to properly monitor and consider the addition of trace elements and byproducts and potential interactions with other naturally occurring drivers.
