Oceanography

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.

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,

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.

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.

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.

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.

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.

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.

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.

Glowing sharks & blue beaches spark curiosity— journey with marine ecophysiologist Dr. Laurent Duchâtelet into the luminous world of ocean bioluminescence. Discover how lantern sharks, dragonfish, plankton and more deploy living light for hunting, hiding and flirting; why wavelengths shift from blue to green to rare red; and how decoding luciferin–luciferase chemistry is powering pollution sensors and cancer diagnostics.

Episode Description: Why the UN declared an Ocean Decade - The United Nations Ocean Decade of Ocean Science for Sustainable Development (2021–2030) is more than a global framework—it’s a chance to rethink how science informs action. In this episode, Alison Clausen, Global Deputy Director of the Ocean Decade at UNESCO’s Intergovernmental Oceanographic Commission, explains what the Decade is aiming to achieve by 2030 and how its legacy will carry forward.

Plastic straws and sea turtles collide in this episode featuring marine biologist Dr. Christine Figgener, whose viral 2015 video of a straw pulled from a turtle’s nose launched a global anti-plastic movement. We explore the long history of sea turtles, the modern threats they face from plastic pollution, and how science and activism can work together to drive change.

How deep sea worms eat without a mouth is just one of the astonishing discoveries in this episode with microbial symbiosis expert Dr. Shana Goffredi. We dive into the strange and beautiful world of methane seeps and hydrothermal vents, where animals form life-saving partnerships with chemosynthesizing bacteria.

Fish full of pharmaceuticals. Submarine groundwater discharge is quietly delivering human contaminants—like heavy metals, fertilizers, and even antidepressants—into our oceans. In this episode of Oceanography, marine geochemist Dr. Tristan McKenzie explains how these hidden pathways are impacting coastal ecosystems around the world. Drawing from fieldwork in Hawaii and Sweden

Whales whisper, volcanoes rumble, and fish sing at sunset. In this episode of Oceanography, host Clark Marchese explores the science of underwater sound with marine biologist and bioacoustics researcher Dr. Jesús Alcázar-Treviño.

New tech is making waves in marine science. In this debut episode of Oceanography, we dive into the world of innovative fishing gear designed to protect endangered species—especially the North Atlantic right whale.
