Establishment of two open-ended Working Groups (WGs): Microplastics in Surface Water WG and Microplastics in Marine Organism WG.


Where the story started

The WESTPAC 10th International Scientific Conference concluded on 20 April 2017, Qingdao, China. During this conference, a number of recommendations have been made towards future marine science development and cooperation in view of the emerging challenges that the region is facing. Among which a keynote speech titled “Marine plastics and microplastics: threats to marine ecosystem” was delivered and a microplastic session was held, which incubated this Ocean Decade Action initially.
