The short (3-min) video summaries the goals of the SF Bay Microplastics Project, a regional program aimed to better understanding the distribution of microplastic in San Francisco Bay and adjacent National Marine Sanctuaries, the pathways by which these contaminants enter the Bay, and possible means of controlling their release. 5 Gyres and San Francisco Estuary Institute are collaboratively carrying out the project.
With funding from the Gordon and Betty Moore Foundation and Patagonia, the project team is still collecting and analyzing data in the field. They look forward to sharing their project results next year.

Plastic pollution is gaining global recognition as a threat to the resilience and productivity of ocean ecosystems. However, we are only just beginning to understand the scope and impacts of microplastic particles (less than 5 mm) on coastal and ocean resources, and the San Francisco Bay Area is no exception. A preliminary study of nine water sites in San Francisco Bay, published in 2016, showed greater levels of microplastics than the Great Lakes or Chesapeake Bay.
A two-year investigation on microplastic and nanoplastic pollution in San Francisco Bay and the surrounding ocean will launch this month, led by two research centers, the San Francisco Estuary Institute and the 5 Gyres Institute.
The RMP has conducted initial studies of microplastic pollution in San Francisco Bay. Findings from a screening-level RMP study of microplastic pollution in our Bay show widespread contamination at levels greater than other U.S. water bodies with high levels of urban development, the Great Lakes and Chesapeake Bay. Wildlife consume microplastic particles; ingestion can lead to physical harm, and can expose aquatic organisms to pollutants like PCBs that the plastics have absorbed from the surrounding environment.
The same week that the U.S. House of Representatives passes a bill to ban microbeads in cosmetic products, the Bay's Regional Monitoring Program releases a fact sheet that describes our recent study on microbeads and other microplastic particles in Bay water and treated wastewater.
Rebecca Sutton, senior scientist at SFEI, describes the hazards presented by microplastics in the Bay's waters. "Plastic pollution: Billions of pieces of tiny plastic litter found in San Francisco Bay," a news article by Paul Rogers reports on findings in a recently published study for which Rebecca Sutton serves as lead author. What the researchers discovered, the high degree of plastic contamination, surprised them.
