The Second World Ocean Assessment (WOA II), the major output of the second cycle of the Regular Process for Global Reporting and Assessment of the States of the Marine Environment, including Socioeconomic Aspects, will be launched on 21 April 2021, in connection with Earth Day 2021 which will be observed on 22 April. It is the newest outcome of the only integrated assessment of the world’s ocean at the global level covering all three pillars of sustainable development.

The first World Ocean Assessment (WOA I), which was released at the end of 2015, established a baseline for measuring the state of marine environment, including socioeconomic aspects. WOA II focuses on trends observed since the publication of WOA I and current gaps in knowledge and capacity.
