Oceanography

Making marine biodiversity visible for everyone Marine biodiversity is vast, complex—and mostly out of sight. In this “ocean story hour” episode, a Paris-based science communicator, Anabelle Chaumun, shares how to translate marine research into stories people can actually feel and remember. We explore why misinformation spreads faster than evidence, why ocean issues can feel distant, and how storytelling (and images) can make the i...

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 ...

Marine heat waves can make summer heat even worse. New climate research shows that unusually warm ocean conditions don’t just damage marine ecosystems — they can also intensify extreme heat on land. In this episode, Mr. Hirotaka Sato, a Japan Meteorological Agency climate scientist explains how marine heat waves form, why the ocean stores most of Earth’s excess heat, and how a 2023 marine heat wave near northern Japan amplified rec...

How oil research protects ocean health. Understanding oil spills, offshore drilling, and marine pollution starts before any accident happens. In this episode, marine microbial oceanographer Dr. Alice Ortmann explains how scientists collect baseline ocean data to measure ecosystem health in oil and gas regions offshore Newfoundland. The conversation covers what counts as an oil spill, how oil and methane move through the water colum...

A legendary research ship’s final sail. For nearly 50 years, the R/V Endeavor served as a floating laboratory for ocean science—supporting 700+ expeditions, training generations of students, and enabling research from CTD/rosette water sampling to seafloor mapping, deep-sea coring, and long-term climate and ecosystem monitoring. In this episode, the ship’s operations manager Brendan Thornton and longtime captain Chris Arminetti tak...

COP30’s biggest fault lines, explained.

In this final installment of our COP30 arc, we zoom out from Belém to map the conference’s defining tensions: ambitious speeches versus stalled outcomes, science-led urgency versus market-led “solutions,” and the growing leadership of the Global South. We unpack why carbon markets remain so contested, what “net zero” really allows, and how China’s energy transition is reshaping the politics o...

The ocean took center stage at COP30. This episode of Oceanography explores how ocean science, policy, and lived experience shaped the climate conversations at COP30 in Belém, Brazil. From marine carbon dioxide removal and blue carbon ecosystem restoration to funding gaps and governance challenges, the episode traces how the ocean is increasingly framed as both a climate solution and a site of urgent risk. It also examines what COP...

Voices from Belém

COP30 brought global climate negotiations to Belém, a city where the Amazon meets the sea. This episode offers a grounded introduction to the conference by centering the people who live there. Activist Catarina Nefertari and artist and event producer Danilo Pontes share what the event meant for their communities, the environmental challenges facing Pará, and how local experiences shape the wider climate conversatio...

Dive into the ocean’s rainforests and how to save them. This episode explores the science and hope behind seaforestation—the restoration of underwater kelp forests that sustain marine life, capture carbon, and protect our coasts. Joined by Scott Bohachyk of OceanWise and James LaFlamme of the Tseshaht First Nation, Clark uncovers how innovative science and Indigenous stewardship are teaming up to revive ecosystems once lost to warm...

 Film sparks action: from screens to shorelines.

In this episode of Oceanography, host Clark Marchese talks with Julie Anderson, CEO and co-founder of Plastic Oceans International, about the Trees & Seas Film Festival and its “participatory film activism” model. We explore how curated films connect to on-the-ground efforts in global Blue Communities, turning awareness into cleanups, tree plantings, and policy conversations....

Turn seawater into a species map. In this episode of Oceanography, host Clark Marchese talks with OceanOmics director Dr. Michael Bunce about how eDNA (environmental DNA), DNA barcoding, and genomics reveal what’s living in the ocean—from microbes to megafauna—using just a few liters of water. We follow the journey from deck to lab, then into powerful, human-friendly AI dashboards that translate massive datasets into decisions abou...

Antarctica’s Hidden Carbon Vault — Beneath the icy surface of the Southern Ocean lies a powerful ally in the fight against climate change: Antarctic blue carbon. In this episode of Oceanography, host Clark Marchese speaks with marine ecologist Dr. Narissa Bax about how deep-sea coral gardens, sponge fields, and seafloor ecosystems around Antarctica are quietly locking away carbon for thousands of years. Together, they unpack what m...

Oceans at Climate Week: What We Learned in NYC — From hopeful storytelling to emerging ocean science, this special solo episode of Oceanography brings you inside New York Climate Week through the lens of the sea. Host Clark Marchese shares how oceans shaped this year’s conversations — from Indigenous leadership and NOAA’s challenges to groundbreaking coral restoration and marine carbon removal. Discover how artists, activists, and ...

What is the Ocean Twilight Zone? Explore the mesopelagic (200–1000 m) and why it’s central to climate, fisheries, and biodiversity. Ocean Conservancy’s Chris Dorsett explains daily vertical migrations, lanternfish and vampire squid, and the biological carbon pump that shuttles carbon to the deep. We unpack emerging pressures—industrial harvest for fishmeal/fish oil, deep-sea mining plumes, and marine carbon-removal trials—and how s...

Antarctic fish with antifreeze blood are revealing critical clues about evolution and climate change. In this special crossover episode from South Pole, marine biologist Dr. Jilda Alicia Caccavo from the Institut Pierre Simon Laplace joins us to explore pelagic notothenioids — fish uniquely adapted to the icy waters of the Southern Ocean. Learn how their antifreeze proteins, colorless blood, and genomic traits help them survive ext...

How do you tell the difference between sound science and pseudoscience? In this special feed drop from All Around Science, we explore the red flags that signal when claims aren’t backed by real evidence — and how to think critically about the information we encounter every day.

At Pine Forest Media, our mission is to make science more accessible, reliable, and engaging. That doesn’t just mean sharing discoveries from the ocean or An...

Dive into Ghana’s coral future with Coral Reef Restoration Ghana, a nonprofit bringing new life to reefs and new opportunities to young scientists. Founder George Amadou and cinematographer David Selasi Kuwornu share how their groundbreaking Dive Lab—the first of its kind in Ghana—trains marine biology students to scuba dive, explore coral reefs, and capture stories through underwater film. We discuss the challenges of ocean access...

Discover how Marine Protected Areas (MPAs) protect our oceans and why California is home to the largest connected network in the world. In this episode, we sit down with Jamie Blatter, climate specialist and tribal liaison at the California MPA Collaborative Network, to explore how MPAs are created, maintained, and measured for success. Learn about the science proving their impact, the importance of community and tribal partnership...

Tiny ocean drifters are shaping Earth’s climate. Microzooplankton, some no larger than a grain of sand, are crucial players in the biological carbon pump — the system that moves carbon from the atmosphere into the deep sea for long-term storage. In this episode, PhD candidate Erin Jones explains how these single-celled organisms regulate climate, why their diversity matters, and what NASA’s EXORTS program is uncovering using satell...
