Oceanography | Marine Science and Ocean Stories: Daily Summaries Delivered
by Pine Forest Media
The ocean is never separate from human life. Oceanography is a marine science podcast about what we know, how we know it, and what we choose to do with that knowledge. Hosted by science communicator Clark Marchese, the show brings researchers, conservationists, policymakers, Indigenous knowledge holders, advocates, and storytellers into conversations that move from discovery to decision-making. We follow whale calls into the deep sea, trace pollution from land to water, visit research vessels and international summits, and ask how ocean science can inform policy that genuinely serves people and the planet. Each episode makes complex research accessible without flattening it, connecting marine biology and ocean discovery with conservation, technology, justice, power, and global policy. Expect deep-dive interviews, narrative explainers, and field reporting grounded in curiosity, rigor, and the belief that understanding the ocean should help us care for it.

Sky Truth: From Satellite Data to Ocean Action
Satellites can reveal what is happening at sea. SkyTruth founder John Amos explains how seeing previously hidden oil slicks from space changed the course of his career, and why he believes environmental data should be free and public. The conversation follows satellite imagery, AIS vessel tracking, and machine learning into tools such as Global Fishing Watch and Cerulean, which make fishing activity and ocean pollution easier to study and respond to. It also examines the limits of satellite ocean monitoring: observation does not automatically prove illegal fishing, coverage remains uneven, and much of the high seas still goes unseen. This is ocean conservation built to move from evidence to policy and action.

How many species are there in the sea? with Dr. Manuel Callebar Guiterrez
How many species are there in the ocean? Marine biologist and taxonomist Manuel Caballero Gutierrez joins Oceanography to explore one of the biggest unanswered questions in marine science: how much life have we actually discovered? From deep-sea expeditions and biodiversity surveys to DNA analysis and museum collections, this episode unpacks how scientists identify, classify, and name new marine species, and why humanity may still know only a fraction of the organisms living on Earth. The conversation explores ocean biodiversity, taxonomy, extinction, climate change, and the growing urgency of documenting life in the sea before ecosystems are permanently altered. A fascinating look at ocean exploration, scientific discovery, and the hidden complexity of life beneath the surface.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 Hosted on Acast.

Elephant Seals Can Be Scientists Too
Elephant seals are helping map the Southern Ocean. This week on Oceanography, we’re sharing a special crossover episode from South Pole, another Pine Forest Media series focused on Antarctic science and research. In this episode, Dr. Clive McMahon explains how southern elephant seals are being equipped with ocean sensors to collect real-time data in one of the most remote and extreme environments on Earth. These deep-diving animals gather information on temperature, salinity, depth, and ocean productivity; especially during the Antarctic winter, when human access is nearly impossible. The conversation explores elephant seal behavior, population decline, Antarctic bottom water, and how animal-borne data is advancing oceanography, climate science, and weather forecasting. A fascinating look at how marine life is contributing directly to scientific discovery.If 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.

Solar Geoengineering: Who Gets to Decide? with Hassaan Sipra
Solar geoengineering is a justice question. As sunlight reflection methods move from theory toward real-world research, who gets to decide what happens next? This episode explores the justice and governance questions surrounding solar geoengineering, also called solar radiation modification or SRM. Hassaan Sipra of the Alliance for Just Deliberation on Solar Geoengineering explains why the risks of climate intervention cannot be separated from existing inequalities in climate change, especially for climate-vulnerable communities in the Global South. The conversation covers environmental justice, public participation, free, prior and informed consent, governance gaps, research transparency, and why climate intervention must never replace emissions cuts, adaptation, climate finance, or loss and damage. A grounded, accessible finale to Oceanography’s marine climate intervention arc.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.

SAI: Should We Reflect More Sunlight to Cool the Earth? with Dr. Kelsey Roberts
Could reflecting sunlight help cool the Earth? Stratospheric aerosol injection, or SAI, is a proposed climate intervention that aims to reduce global temperatures by reflecting a small portion of incoming sunlight. Inspired by volcanic eruptions, this approach is being studied through climate and ecosystem models to better understand its potential effects. This episode explores how SAI could influence sea surface temperature, net primary production, ocean chemistry, and marine food webs. It also looks at how scientists use models to evaluate different deployment scenarios, including long-term use and phase-out strategies. Along the way, the conversation considers uncertainty, regional variability, and the role SAI might play within a broader portfolio of climate responses.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 Hosted on Acast.
