Science Toward Solutions: Ocean Microplastic Research with Dr. Winnie-Courtene Jones

What have we learned about microplastics over the last 20 years? This episode surveys two decades of ocean microplastics science: where microplastics come from (fibers, tires, fragmentation, microbeads), where they’re found (shorelines, water column, sea ice, deep sea), and what research shows about impacts across food webs and ecosystems. It also unpacks major gaps—nanoplastics, fragmentation rates, and the thousands of chemicals used in plastics—plus why scientists argue for a precautionary approach even as human-health research evolves. Finally, learn how microplastics are measured at sea (manta trawls, spectroscopy) and why contamination control matters. The episode connects the science to policy, including the UN Plastics Treaty debates over production cuts vs waste management.Support our science communication by joining us on Patreon or sending us a gift on PayPalSpecial thanks to the Monterey Bay Aquarium for sponsoring this episode.Episode Guests: Dr. Winnie Courtene-JonesFollow Dr. Courtene Jones on Blue SkyFind the article 20 Years of Microplastic Research: What have we learned?Connect with the Scientists’ Coalition for an Effective Plastics Treaty on LinkedInReview Dr Courtene-Jones’ publications on Google ScholarExplore artwork by Benjamin Von WongListen to Plastic Podcast on Spotify or Apple PodcastsPlastic Podcast: The Truth about Biodegradable PlasticsPlastic Podcast: Busan and Beyond - A UN Treaty on Plastics Episode Transcript and more information on the Pine Forest Media websiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, and edited by Clark Marchese Cover art by Jomiro EmingTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Plastic Podcast on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.
