The Hidden Pipeline: How Human Pollution Seeps into the Sea with Dr. Tristan McKenzie
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, he breaks down the science behind groundwater pollution, shares the results of a global contamination risk map, and discusses the surprising ways contaminants disrupt both marine life and biogeochemical cycles. You’ll also learn why some of the world’s most biodiverse coasts are at highest risk—and how you can help. This is a deep dive into ocean contamination, climate interactions, and the data behind it all.

What does the ocean sound like? with Dr. Jesús Alcázar-Treviño
Episode Description: 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. You'll learn how toothed whales use echolocation to hunt in the deep sea, how volcanic eruptions reshape marine soundscapes, and why some whales may be mistaking plastic for prey. We also dive into the impacts of human-made noise—like shipping and seismic testing—on marine ecosystems. With fascinating stories from the Canary Islands and deep-sea research insights, this episode is your gateway into the hidden world of ocean acoustics and marine conservation.Support our science communication by joining us on Patreon or send us a gift on PayPalEpisode Guest: Dr. Jesús Alcázar TreviñoLearn more about Dr. Jesús Alcázar Treviño hereFollow Dr. Jesús Alcázar Treviño on Blue SkyFind more of Dr. Jesús Alcázar Treviño’s work on Research GateExplore more from the Spanish Institute of Oceanography 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 RuizListen to South Pole on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.

How to save the whales (like, actually) with Megan Amico
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. Guest Megan Amico, a fisheries biologist with NOAA, shares how scientists and fishermen are working together to reduce harmful bycatch through smart design, including on-demand lobster traps and turtle excluder devices. It’s a story of unlikely partnerships, inventive problem-solving, and measurable success. If you care about marine life, sustainable fisheries, or just love a good science story, this is one you won’t want to miss. Learn how collaboration is helping coastal communities thrive while giving ocean wildlife a fighting chance.Episode Guest: Megan AmicoLearn more about Megan Amico hereNOAA Protected Species Gear Research: Visit HereNOAA’s Endangered Species List and Action Plans: Browse ListSupport the science communication and Pine Forest Media on PatreonEpisode 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 RuizListen to South Pole on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.

Oceanography Trailer
Oceanography is a marine science podcast about the research happening beneath the surface—literally. It’s where your favorite science 101 class meets environmental journalism, with weekly conversations featuring marine biologists, oceanographers, and climate scientists from around the world. One week we might explore whale communication or how sound travels underwater; the next, we’re looking at fishing gear designed to protect endangered species. You'll also hear about ocean conservation, deep sea ecosystems, microplastic pollution, and the surprising ways marine life is connected to life on land. If you're curious about the ocean and want to hear from the people uncovering its secrets, you’re in the right place. Hosted on Acast. See acast.com/privacy for more information.
Oceanography is a weekly marine science podcast exploring the latest ocean research, climate science, and environmental discoveries.
