Oceanography

Naming ocean life is the first step toward protecting it. In a live conversation with his former professor, host Clark Marchese asks marine biologist Dr. Manuel Caballero Gutiérrez how many species live in the sea and why the answer remains uncertain. The episode follows marine taxonomy through deep-sea expeditions, DNA analysis, museum collections, and formal species descriptions, connecting species discovery with marine biodiversity, extinction risk, and conservation.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guests: Dr. Manuel Callebar GutierrezBrowse Dr. Callabar Gutierrez's publications on Research GateListen to Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYEpisode 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

What happens at the deepest points of the ocean? This week on Oceanography, we’re sharing a special feed drop episode from Deep Sea Pod, hosted by Thomas Linley and Alan Jamieson — two scientists many of you may already recognize from previous Oceanography episodes like What Is the Deep Sea Even Like? and Ocean Trenches Explained.In this episode, Professor Alan Jamieson takes listeners on a deep dive into the hadal zone: the deepest and most extreme region of the ocean, including the massive trenches that extend nearly 11 kilometers beneath the surface. The conversation explores how scientists study these remote environments, what kinds of organisms survive under immense pressure, the history of deep trench exploration, and why the hadal zone remains one of the last great frontiers in marine science.If you enjoy the episode, be sure to check out Deep Sea Pod using the link in the episode description.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guests: Alan Jamieson and Thomas Linley Listen to Deep Sea PodFind some more Pine Forest Media podcasts below Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYListen 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

Where does climate change stand as 2026 unfolds? This Green Frequency crossover steps back from the ocean to assess the wider climate system. Climate scientist Dr. Claudio Piani and student activist Averie Gannon examine global emissions, the Paris Agreement, renewable energy progress, and why every fraction of a degree still matters. It is a grounded climate change 2026 briefing on what is improving, where the gaps remain, and why climate action is still consequential.Listen to Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYSupport our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guest: Dr. Claudio Piani Special thanks to the American University of ParisOur World In Data - CO2 emissions, temperature, and per capita trends.The Scientific American - Global Average Temperature TargetsInternational Renewable Energy Agency - The Cost of Renewable EnergyExplore the Pine Forest Media digital ecosystem on our websiteFind the full-length video on YouTube @PineForestPodsFollow us on Social Media @pineforestmediaHosted by Clark Marchese and Averie GannonAudio Editing by Clark Marchese, Video Editing by Oscar PadulaVideography and Set Design by Le Studio Du PassageCover Art by Laurel WongTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Oceanography on Spotify or Apple PodcastsListen 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

Elephant seals collect data where ships rarely can. In this South Pole crossover, Dr. Clive McMahon explains how animal-borne sensors turn deep-diving southern elephant seals into partners in Southern Ocean monitoring. The tags collect temperature, salinity, depth, and ocean productivity data, especially during the Antarctic winter. The episode also explores seal behavior, population decline, Antarctic Bottom Water, climate monitoring, and how hard-to-reach observations improve oceanography and weather forecastingIf you enjoy this episode, you can find more from South Pole, a series dedicated to the science of Antarctica, on Spotify or Apple Podcasts, or all major platforms.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guest: Dr. Clive McMahonReview the research publication discussed in the episode hereVisit Dr. McMahon’s publications on Google Scholar Visit the website of the Sydney Institute of Marine SciencesEpisode Transcript and more information on the Pine Forest Media WebsiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, written, and edited by Clark Marchese Cover art and PFM logo by Laurel Wong. Theme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Oceanography on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts

Solar geoengineering is also a question of power. Hassaan Sipra of the Alliance for Just Deliberation on Solar Geoengineering explains the governance and climate justice issues surrounding solar radiation modification. The conversation centers Global South and climate-vulnerable communities, meaningful participation, consent, research transparency, and the absence of robust international rules. It also makes clear that climate intervention cannot replace emissions cuts, adaptation, finance, or loss and damage.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guests: Hassasn SipraLearn more about justice and SRM on the DSG website. Listen to Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYEpisode 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

Cleaner ship fuel created a climate experiment. Meteorologist Dr. Michael Diamond explains how shipping emissions influence cloud formation above the ocean and how the IMO sulfur cap changed that signal. Combined with disruptions to major shipping routes, the policy gave researchers a rare natural experiment for studying aerosols, clouds, and climate. The results also inform current questions about marine cloud brightening without turning past pollution into an argument for deployment.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guests: Dr. Michael DiamondFind Dr. Diamond’s published article on the impacts of the IOM regulation and preprint on the impacts of a changed shipping route. Review Dr. Diamond’s publications on Google ScholarListen to Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYEpisode 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

Reflecting sunlight would also change the ocean. Dr. Kelsey Roberts explores stratospheric aerosol injection through ocean and marine ecosystem models. The conversation examines possible changes to sea surface temperature, ocean chemistry, net primary production, fisheries, and food webs under different scenarios. It also explains why modeling is useful at this early stage and why the uneven ecological, economic, and social trade-offs belong inside any discussion of solar radiation modification.Support our science communication by joining us on Patreon or sending us a gift on PayPalEpisode Guests: Dr. Kelsey RobertsFind Dr Robert’s publication on the Potential Impacts of Climate Intervention on Marine EcosystemsReview Dr. Robert’s publications on Google ScholarFind more resources on geoengineering at GeoMIPLearn more about Justice and Governance about SRM Technologies at DSGListen to COP30: Green Power for more on global climate policyEpisode 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

Brighter marine clouds could cool parts of the ocean. Climate scientist Dr. Jessica Wan explains marine cloud brightening, a proposed solar geoengineering method that would add sea-salt particles to low marine clouds. Learn how stratocumulus clouds reflect sunlight, what climate models suggest about regional cooling, and why scale, uncertainty, side effects, and governance matter.

Can the ocean keep carbon out of the atmosphere? Oceanographer Dr. Morgan Raven explains marine carbon dioxide removal and the search for environments that can store organic carbon for long periods. The conversation moves through mangroves, fjords, oxygen-poor waters, and deep-sea brines to examine ocean carbon sequestration. It also makes the uncertainties clear, including measurement, ecological risk, coastal differences, and what must be proven before any method can scale.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
