Sea to Source - Collecting Observational Data

Sea to Source - Collecting Observational Data

Imogen Napper is a marine scientist studying how microplastics enter and affect natural environments. On the Sea to Source expedition to the Ganges River, Imogen took samples from every possible source to see where those microplastics were coming from. Learn how Dr. Napper measures microscopic pieces of plastic in the river's waters, along its banks, and even in the air. Understanding where they come from will hopefully help us eventually eliminate these toxic plastic particles from our lives.
