Under the waves

If you've ever wondered what lurks in the deep, Greenpeace UK's Oceans: Life Under Water delivers an immersive dive into the unknown. Hosted by wildlife filmmaker-zoologist Hannah Stitfall, the podcast balances awe-inspiring marine science with urgent conservation discussions.

In the episode Oceans Deep, Stitfall talks to submarine pilot and explorer John Hocevar, who takes us on a journey to the ocean floor, describing its eerie quietness, bizarre inhabitants and vast mysteries still unsolved. His first-hand accounts - like discovering an entirely new species - are thrilling, making the deep sea feel both alien and integral to our planet.

Hocevar's reflections highlight just how little we know about the ocean, even though it covers most of Earth and carries most of 'terrestrial' life. He also emphasises the urgency of protecting these ecosystems before human impact becomes irreversible.


With its mix of exploration, environmental urgency and storytelling, the podcast engages ocean lovers and conservationists alike. Whether you're fascinated by deep-sea creatures, curious about Maori connections to the ocean or concerned about marine ecosystems, this podcast makes the case for why the ocean matters.
