. Ocean microplastics: First global view shows seasonal changes and sources « JO LEE MAGAZINE

PHYS.org – An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics—tiny flecks that can ride currents hundreds or thousands of miles from their point of entry. The debris can harm sea life and marine ecosystems, and it’s extremely difficult to track and clean up. Now, University of Michigan researchers have developed a new way to spot ocean microplastics across the globe and track them over time, providing a day-by-day timeline of where they enter the water, how they move and where they tend to collect.
