Oceanography

What is biocultural coastal conservation — and why does it matter for the future of our oceans? In this episode, conservation scientist Juan Carlos Cruz of the Amazon Conservation Team explains how Indigenous knowledge and Western marine science are being woven together through the Ancestral Tides initiative.

Across Costa Rica, Panama, Mexico, Colombia, and Suriname, coastal Indigenous and local communities are protecting sea turtles, coral reefs, mangroves, and critical nesting beaches using community-based conservation strategies. This work combines biological monitoring, sea turtle tagging, hatchery protection, GPS tracking, fisher partnerships, and livelihood-based conservation — all grounded in ancestral knowledge systems.

We explore:
• What biocultural conservation actually means
• Why sea turtles are biocultural keystone species
• How Indigenous-led conservation strengthens marine ecosystems
• The connection between coral reefs, fisheries, and food security
• How land and sea conservation must work together

Sea turtles migrate thousands of kilometers across oceans — linking forests, beaches, reefs, and coastal communities. Protecting them requires protecting the full ecological and cultural system they move through.

This conversation highlights a growing global shift: conservation that centers community leadership, respects traditional knowledge, and recognizes that protecting biodiversity also means protecting culture.

Ocean trenches are Earth’s deepest habitats—and they’re full of life. This episode is a guided dive into the hadal zone (6,000–11,000 meters), where tectonic plates create steep trenches that plunge toward the mantle. Learn what trenches are geologically, what conditions are like at full ocean depth (cold, pressure, darkness), and why the deep sea isn’t a single ecosystem—each trench is its own world. You’ll also get myth-busting on how “the abyss” shows up in pop culture, plus an inside look at the technology that makes trench science possible: multibeam mapping, baited landers, and human-occupied submersibles. Finally, we explore the big research questions scientists are asking about biodiversity, evolution, and connectivity across the deepest ocean.

What is the deep sea — really? Deep-sea researcher Dr. Thom Linley (Curator of Fishes at Te Papa Tongarewa, National Museum of New Zealand) breaks down the deep ocean as a connected world with distinct zones, ecosystems, and rules — not one mysterious “blob.” From the bathyal and abyssal to the hadal trenches, this conversation maps what’s down there, how life survives crushing pressure and perpetual darkness, and why the deep sea functions as the engine under the hood of the entire planet.

This episode explores:
What counts as “deep sea” (and why the definition is changing)
The major deep-sea zones and how they blend into each other
Whale falls — the deep ocean’s sudden “feast events” and the strange life they power
Why trenches can be food-rich funnels (and why that matters)
How deep-sea animals adapt at the molecular level (cells, fats, enzymes)
The technology that makes deep-sea science possible: landers, traps, cameras, and autonomous systems
The reality of deep-sea pollution: plastic and “forever chemicals” showing up even at extreme depths
Why museum collections are time capsules for future ocean science

And this is part one of a deep dive: next episode continues into ocean trenches and the hadal zone with Prof. Alan Jamieson, co-host of The Deep Sea Podcast.
If you’re into thoughtful mythbusting, weird deep-ocean ecology, and the real logistics of studying a place humans can barely access — you’re in the right place.

Ocean oxygen shapes marine life in ways most of us never think about. This episode explores how oxygen enters the ocean (air–sea exchange and photosynthesis), how it circulates through surface waters and the deep sea, and why scientists track changes in oxygen over time. Learn what oxygen minimum zones are, how they form, and what they can mean for midwater ecosystems in the mesopelagic (“twilight”) zone.

Featuring research that uses fossil fish ear bones (otoliths) preserved in seafloor sediment, the conversation looks back thousands of years to reconstruct a past oxygen shift in the Mediterranean—and what long-term records can teach us about ocean dynamics today.

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 invisible ocean world tangible. Anabelle also introduces EMBRC (the European Marine Biological Resource Centre) and how its network of marine stations supports research that improves food safety, sustainable aquaculture, and ecosystem understanding across Europe. Along the way, we dig into solutions-oriented communication, ethics, representation, and documentary photography as a tool to amplify communities often missing from environmental narratives.
