Antarctic seafloor life stores carbon for centuries. Marine ecologist Dr. Narissa Bax explains Antarctic blue carbon, the carbon captured and stored by marine organisms and ocean habitats. The episode follows carbon from phytoplankton through cold-water coral gardens, sponge fields, kelp, and other seafloor ecosystems, where some of it can eventually be buried in sediment for hundreds or thousands of years. Bax examines the growing scientific effort to measure this seafloor carbon storage, its relationship with biodiversity, and how blue carbon could support marine protected areas and conservation policy. The discussion also considers bottom trawling, carbon credits, and the limits of presenting Antarctic blue carbon as a simple climate solution.Support our science communication by joining us on Patreon or sending us a gift on PayPalEpisode Transcript and more information on the Pine Forest Media websiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, and edited by Clark Marchese Find Dr. Narissa Bax website here. Read Dr Bax’s publication: The Growing Potential of Antarctic Blue CarbonEpisode 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

Elephant seals collect data beneath the Southern Ocean. Dr. Clive McMahon explains how researchers equip southern elephant seals with miniature conductivity, temperature, and depth sensors. As the seals dive and travel through remote waters that are difficult to observe, especially during winter, the animal-borne sensors collect information about temperature, salinity, depth, and ocean productivity before transmitting observations by satellite. The data help scientists study elephant seal tracking, foraging, body condition, and population change while improving Southern Ocean monitoring. They also reveal physical processes connected to Antarctic dense water, global ocean circulation, weather, and climate.Episode 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

Jackie Ronne changed who could explore Antarctica. Polar historian Dr. Joanna Kafarowski recounts how Ronne joined the Ronne Antarctic Research Expedition in 1947 as a full expedition member and became one of the first two women to overwinter on the continent. The episode follows her journey from the National Geographic Society to Antarctica, where male expedition members initially signed a petition opposing the women’s participation. Learn how Ronne contributed to expedition operations and scientific objectives while facing isolation, sexism, and extraordinary pressure. Her story reveals the institutional barriers that kept qualified women out of polar exploration for decades.Episode Guest: Dr. Joanna KafarowskiVisit Dr. Kafarowski’s website hereConnect with Dr. Kafarowski on LinkedInFind: Antarctic Pioneer: the Trailblazing Life of Jackie RonneFind: The Polar Adventures of a Rich American Dame: The Life of Lousie Arner BoydEpisode 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

The Antarctic Treaty turned rivalry into cooperation. Political and environmental philosopher Dr. Alejandra Mancilla traces how overlapping territorial claims, international tensions, and the Cold War led twelve countries to sign the Antarctic Treaty in 1959. The resulting Antarctic Treaty System set the continent aside for peaceful purposes and international scientific cooperation while effectively freezing competing territorial claims. The episode explores environmental protection, membership and decision-making, questions of political legitimacy, and the pressures climate change could place on polar governance. It also asks what the treaty’s model of shared guardianship might teach the rest of the world.Episode Guest: Dr. Alejandra MancillaVisit Dr. Mancilla’s websiteFind Dr. Mancilla’s article hereBrowse Dr. Mancilla’s publications on Google ScholarLearn more about the Antarctic Treaty hereSouth Pole: What if Antarctica had Legal Personhood?Read Antarctic journalist Tiara Walter’s work 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 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

Women are written across the map of Antarctica. Researcher and writer Carol Devine connects two projects exploring polar history and environmental stewardship. Mapping Antarctic Women traces place names honoring queens, sponsors, family members, scientists, explorers, and other women whose stories are embedded in the continent’s geography. Devine also recounts Cleanup Project Antarctica, a 1990s initiative in which volunteer teams worked with Polish and Russian research stations to remove legacy waste and raise awareness of the Antarctic Treaty’s environmental protections. Together, the projects reveal how maps, historical recognition, activism, and hands-on conservation shape Antarctica’s human story.Episode Guest: Carol DevineLearn more about Carol Devine hereFollow Carol Devine on InstagramFollow Carol Devine on XFind The Antarctic Book of Cooking and Cleaning on Good Reads and Harper CollinsRead about the Mapping Antarctic Women project here Find the Map of Antarctic Women hereEpisode 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 Ruizhf8G6WG2xCPX0XYyU5e0

Antarctic soil offers a preview of a warmer continent. Geomorphologist and planetary scientist Dr. Joe Levy takes listeners into the McMurdo Dry Valleys, where water, ice, salt, microbes, and sediment interact in one of Earth’s coldest deserts. Learn how Antarctic soil forms, why seasonal water tracks resemble miniature wetlands, and what permafrost thaw and summer melting could mean for a greening Antarctica. Levy also explains how these Mars-like landscapes preserve evidence of past climates and serve as a valuable Mars analog for planetary science. More Antarctic life may emerge as conditions warm, but that transformation is not necessarily good news for existing ecosystems.Episode Guest: Dr. Joe LevyLearn more about Dr. Levy hereBrowse Dr. Levy’s publications hereFollow Dr. Levy on XLearn more about the Cold Dirt Lab hereEpisode 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 Ruiz

Antarctica is not as silent as it first appears. Musicologist and Antarctic studies scholar Dr. Carolyn Philpott explores how sound, silence, and music shape the ways people experience and imagine the continent. From songs performed during early polar expeditions and Vaughan Williams’s Antarctic film music to field recordings, iceberg cracks, wildlife, and modern soundscape compositions, the episode reveals Antarctica’s rich acoustic identity. Philpott also introduces ecomusicology and explains how Antarctic soundscapes, tourism, and sensory experience can build emotional connections with a place most people will never visit.Episode Guest: Dr. Carolyn PhilpottLearn more about Dr. Philpott hereBrowse Dr. Philpott’s Publications hereConnect with Dr. Philpott on LinkedInListen to Vaughn Williams’ Scott of the Antarctic on YoutubeListen to Penguin Ballet by Nigel Westlake on Spotify Listen to Seals (Underwater) by Douglass Quinn on YouTubeListen to Antarctic Sound Recordings by Phillip Samartzis on YouTubeIceberg Crash by Almaz KhakimovEpisode 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 Ruiz

A legal movement wants Antarctica to have rights. Environmental lawyer Cormac Cullinan introduces Earth jurisprudence, the rights of nature, and the Antarctic Rights initiative. What would change if Antarctica could be represented in legal and political decisions, and if governments were required to consider the continent’s own interests? The conversation examines potential representatives, enforcement, examples from other rights-of-nature movements, and perceived gaps in the Antarctic Treaty System. This is an exploration of Antarctic governance and environmental law, presenting legal rights for Antarctica as an active proposal rather than established law.Episode Guest: Cormac CullinanLearn more about Cormac Cullinan hereLearn more about Antarctic Rights hereGet involved with Antarctic Rights hereLearn more about Wild Law hereEpisode 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 Ruiz
