What lies at the bottom of the ocean? Far below sea level. In areas that humans have never touched.

Sandor Mulsow is going to help us answer those questions. He is a marine scientist, turned full time campaigner, who spent decades studying the ocean floor. He’s here to tell Hannah about the delicate ecosystems that so few know about. And Diva Amon introduces us to a new marine threat, which could change the deep sea forever.

And Andrew Sweetman joins us, to tell us about a new discovery that changes what we thought we knew about the seafloor.

Plus, we share the first glimpse of Hannah’s adventure to the Arctic. More on that to come.

We’ve been on a journey beneath the waves, and now we’re back. To explore the deepest and darkest corners of the ocean.

What does it take to survive in a place that light cannot reach? And how many of these creatures remain undiscovered?

Wildlife filmmaker and broadcaster Hannah Stitfall is joined by marine biologist Helen Scales, to discuss some of the most unusual creatures living in the deep sea. And science communicator, Diva Amon, tells us what it’s like to be submersed far below sea level.

Hannah has also been on a journey of her own. Which we’ll tell you more about, later in the series.

In this final episode, we're looking to the future. The Oceans Treaty which was finally passed last year after decades of negotiations was momentous - but what actually is it? And will it do anything? Senior Policy Advisor Lisa Speer was at the UN HQ in New York when the announcement was made, and joins Hannah to break down what it means, why it's exciting - and what obstacles still stand in the way.

Hannah speaks with Hawaiian community leader Uncle Sol about his island's relationship to the ocean and what the Oceans Treaty means to him; and she also meets Marion Atieno Osieyo, creator and host of the award-winning Black Earth Podcast, for an inspiring chat about the future of conservation.

Everyone knows the oceans are changing. Sea levels are rising, the water's heating up, coral is bleaching. But away from the scary stats, what do the changing oceans actually look like - what impact are they having on us now? Hannah is joined by climate activist Shaama Sandooyea, who explains how climate change is impacting her home nation of Mauritius, and grammy-nominated DJ and environmental toxicologist Jayda G travels to the studio to tell Hannah about her new CNN film, 'Blue Carbon.'

Also - you'll meet Wilson dos Santos, known locally as Safico, one of a community of fishermen from Laguna in southern Brazil who have developed a unique working relationship with the dolphins there. Many thanks to Safico the fisherman, to Ana Cremer Dotto for doing the interview and to João Valle Pereira for the translation.

Hannah's been getting updates from onboard the Arctic Sunrise, one of Greenpeace's research ships, since the beginning of the series - from Panama where it set sail out into the Galápagos Islands marine reserve. We heard as it crossed the equator, and we've learnt about the pioneering research the scientists and volunteers have already done on seamounts in the area. And now, they've finally anchored and we're joining them onboard for an episode all about Galápagos.

You'll meet Sophie Cooke, the expedition lead; Captain Mike, the man behind the wheel; Andrea Vera, an Ecuadorian scientist; and Hannah is lucky enough to be able to catch up with Spanish Actress Alba Flores (from Netflix's Money Heist), who's just got back home after spending a week onboard.

Hollywood has a lot to answer for when it comes to how we view sharks. The Great White, we all know. But sharks have been around since before the dinosaurs, and in that time they've evolved into 538 different species of all different shapes and sizes - and counting. Sharks with glow-in-the-dark armpits, sharks that can fit in your pocket, sharks with spots, sharks with frills. Isla Hodgson joins Hannah in the studio, and she's got some astonishing shark facts up her sleeve.

Also - you'll meet Shaama Sandooyea, a climate activist from Mauritius who staged the world's first ever underwater climate protest.

3 billion people rely on the oceans for their livelihoods. But who are they? What are their stories? Hannah's moving away from the ocean's wild animals and meeting its humans instead. She's joined by lifelong fisherman Jerry Percy, and speaks with freediver and ocean advocate Hanli Prinsloo about who the oceans are for.

Also - Frida Bengtsson, a researcher who focuses on fisheries, tells her success story of working with fisheries in the Barents Sea.

They're like aliens from another planet. There are over 300 species and counting, from the size of your fingernail to 10 metres across. They live on the ocean's surface, and in its darkest depths. But how intelligent are they, really? How do they use tools? And what's it like to meet one in the wild? Eminent marine biologist and science communicator Helen Scales joins Hannah in the studio.

Also - meet Gretchen Früh-Green, one of the scientists who discovered the Lost City, which some believe could be the origin of all life on Earth.
