Microplastics collected from Adventure Scientists — global microplastic volunteer initiative in Global Ocean from 2013-07-01 to 2017-03-30 (NCEI Accession 0211009)

The Global Microplastics Initiative of Adventure Scientists conducted surveys of microplastics pollution in aquatic ecosystems from 2013-2017. In this project, Adventure Scientists, in partnership with Ocean Analytics, conducted a Global Microplastics Initiative in order to fill a data gap critical to addressing the problem. The initiative utilized a network of trained volunteers to collect water samples across the world’s oceans. 1,058 volunteer-led expeditions collected 2,677 water samples over four years and spanning each continent and every ocean. The data contain microplastic pieces per L of water.
