Oceans: Life Under Water

Antarctica is one of the harshest environments you can imagine. Winds can reach 200mph and the lowest temperature ever recorded was -89 degrees Celsius. But the monochrome above the waves is matched by the explosion of colour beneath them. The Southern Ocean is home to more than 9000 species, many of which can only be found there. Hannah is joined by scientist Lucy Woodall, who led the first expedition to find Shackleton's ship Endurance, and Antarctic historian John Dudeney.

Also - meet Bhakti Sharma, the youngest person and the first Asian to complete a long-distance swim in all five oceans, the most recent being the Southern Ocean.

Hannah's asking all the questions you ever wanted to know about whales. Did you know they have culture? She's joined by whale legend Hal Whitehead, whose close encounters with sperm whales and understanding of their culture has completely changed how we view these enormous animals.

Also - we've had an update from the team onboard the Arctic Sunrise, the research ship that's on its way to the Galapagos Islands.

What does the bottom of the ocean look like? What animals can exist down there, with no sunlight? And how deep is the ocean, really? Hannah is joined by the submarine pilot John Hocevar.

And you'll meet Quack Pirihi, who explains why they can't be Maōri without the oceans.

The world's longest mountain range is actually in the middle of the ocean - the mid-Atlantic ridge, at more than 40,000 miles long. But who knows about these mountains? How high are they? Where are they? What lives on them? Hannah is joined by South African actress and TV presenter Amanda Du Pont, who spent two weeks on a Greenpeace ship on a research expedition to Mount Vema in 2019. And she welcomes marine scientist Lucy Woodall back into the studio, who's led expeditions to seamounts all around the world.

Also - there's another update from the Arctic Sunrise en-route to the Galapagos Islands. They've made a stop-off at the ocean mountains near Galapagos.

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.
