mCDR: Can the Ocean Store Our Carbon for Centuries? with Dr. Morgan Raven

We may need to remove carbon from the atmosphere—can the ocean help? Biomass-based marine carbon dioxide removal (mCDR) explores whether natural ocean processes can help store carbon for the long term. Oceanographer and biogeochemist Dr. Morgan Raven explains how organic carbon moves through marine systems, why low-oxygen environments like deep-sea brines and fjords may enable long-term carbon sequestration, and what scientists still need to understand before these approaches can scale. This episode explores marine carbon dioxide removal, carbon sequestration, blue carbon, and ocean biogeochemistry, while addressing uncertainty, environmental risk, and the role these strategies might play alongside emissions reduction. A clear, grounded look at one of the most complex and debated frontiers in climate science.Support our science communication by joining us on Patreon or sending us a gift on PayPalEpisode Guests: Dr. Morgan RavenReview Dr. Raven’s publications on Google ScholarCheck out the work of the NOISE LabListen to COP30: Oceans on the Rise? for more on mCDR 10 New Insights in Climate Science for 2025 by Future Earth 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 South Pole on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.
