We don’t often think of plastics as having “fingerprints.” But they do. And, as we continue to find microparticles in unexpected places — from local anchovy and seabird guts to the deepest trenches of the ocean — identifying those fingerprints is increasingly important.
Scientists at the Monterey Bay Aquarium and MBARI recently published an open-access library — a collection anyone can use for free — of the chemical fingerprints of microplastics and other particles that are commonly found in and around the ocean. Researchers can use the library to figure out what kind of plastics are entering the ocean, where they are coming from and what we can do to
