The designation of large high seas MPAs, which are more than 200 nautical miles from land, will also pose a major challenge to their proponents who will need to plan assessment and management regimes for activities taking place across potentially vast areas of open ocean. This will require exponential access to, and capacity to process, "big data"-from a large number of diverse sources across ecological, economic, scientific, and industrial domains. This article highlights the challenges of future ABNJ governance and the need for a generation shift in sensing and analysis capabilities. It shows how some of these emerging tools have been used in various domains and their advantages as well as some challenges and potential constraints. The experience of the Sargasso Sea project will be used to highlight the role of big data and AI in developing an accurate assessment of a large marine ecosystem (LME).
