The NOAA NCEI marine microplastics database
Summary
NOAA has created a global open-access database for marine microplastic data, providing standardized and searchable records from researchers worldwide through an interactive map and data portal. The database addresses a major gap in microplastic research by making fragmented data from many studies comparable and accessible. This kind of coordinated monitoring is essential for understanding the full scale of microplastic pollution in the oceans and its potential effects on human health through seafood and coastal environments.
Microplastics (<5 mm) pollution is a growing problem affecting coastal communities, marine ecosystems, aquatic life, and human health. The widespread occurrence of marine microplastics, and the need to curb its threats, require expansive, and continuous monitoring. While microplastic research has increased in recent years and generated significant volumes of data, there is a lack of a robust, open access, and long-term aggregation of this data. The National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI) now provides a global open access to marine microplastics data on an easily discoverable and accessible GIS web map and data portal ( https://www.ncei.noaa.gov/products/microplastics ). The objective of this data portal is to develop a repository where microplastics data are aggregated, archived, and served in a user friendly, consistent, and reliable manner. This work contributes to NCEI's efforts towards data standardization, integration, harmonization, and interoperability among national and international collaborators for monitoring global marine microplastics. This paper describes the NOAA NCEI global marine microplastics database, its creation, quality control procedures, and future directions.
