SDG target 14.3, which calls to “minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels.” The associated SDG target indicator (14.3.1) focuses on “average marine acidity measured at an agreed suite of representative sampling stations.”

However, there has been a lack of guidance in how to go about measuring ocean acidification — until now! The Global Ocean Acidification Observing Network (GOA-ON) Executive Council have announced a finalised methodology for the SDG target indicator 14.3.1 on marine acidity. This methodology outlines how to collect information that is transparent, traceable and globally comparable.
