Bathed in warm, clear tropical water and brilliant sunlight, coral reefs are the rainforests of the sea. Surrounded by ocean deserts, they are rich oases of life. Spectacular numbers make it necessary to stand out to survive. This competition is highly visible as brightly coloured fish compete for food, territory and mates. But the corals themselves are also dynamic. Incredible time-lapse photography shows the dramatic formation of a coral reef, portraying its myriad inhabitants and its ultimate destruction.
Endless blue stretches in every direction. The sea bed is a staggering 8km deeper down and the nearest island is 500km away. There is nothing save the burning sun above and the blackened abyss below. How, then, does life exist?
Life on the edge of a frozen sea is tough. Pack-ice at both poles is constantly on the move and, in winter, freezes solid with air temperatures 70 degrees below freezing. Only in spring, with the retreating ice and light reaching the water, does life begin again. Plankton blooms and feeds vast hordes of migrating fish, birds, whales, seals and polar bears. Walruses rake the seabed for clams. Minke and humpback whales gorge themselves on gigantic swarms of krill. But it is a brief indulgence, for the ice soon returns and pushes life back into the ocean.
The deep sea - which gets darker till no more sunlight penetrates at about a kilometre depth and ever colder closer to the bottom of the ocean - covers most of the planet and is, thus, by far the largest habitat on earth, yet, it has been explored less than space.
The blue whale is a perfect symbol for the oceans, the vast blue expanse that dominates our planet while remaining largely unexplored and mysterious. Yet the oceans are an integral part of our lives. Their influence dominates the world's weather systems. They support an enormous range of life, from the largest whales to the smallest plankton, from hordes of sea birds to lonely deep-sea fish. All this is governed by a complex system of biological and physical forces. This first episode demonstrates the sheer scale, power and complexity of our Blue Planet.
Julia explores Russia and Ukraine's culinary delights, from well known traditional dishes to modern fusion cuisine. Julia tours a market in Kherson, searching for quintessential flavours, sampling as she shops. She then heads to Russia's most exclusive restaurant, Cafe Pushkin, to taste their take on Russia's most famous soup: borsch.

The public supports Australia joining the Vietnam War - but not conscription - until the toll becomes apparent. Awareness grows about discrimination and the extent of everyday racism against Indigenous people, and about land rights. Gender inequality in the workforce and elsewhere also becomes an issue in the 1960s.
David Dimbleby sails along the coast of East Anglia, exploring how Britain's view of the sea has changed over the past 200 years. The coast and the beach became a playground for the nation, inspiring artists, transforming coastal architecture and creating a seaside culture that remains uniquely British. Setting out from Gorleston-on-Sea, he travels down the Suffolk and Essex coasts and into the Thames, until he reaches Greenwich. Along the way he discovers works of art that reflect Britain's evolving relationship with the sea, meets a sand sculptor and visits the Queen's House in Greenwich, built in 1616 as a waterside retreat for Queen Anne and now home to Britain's greatest collection of maritime artefacts.
Julia explores Kherson, a town in regional Ukraine still largely unchanged since Soviet times, then visits tourist playground Odessa. Julia takes a look around Kherson, a working-class town in southern Ukraine. It's old and crumbling, unlike the postcard-friendly scenes of Kyiv.
The government adopts the slogan "populate or perish" after World War II and immigration changes the face of Australia. This influx of labour, as well as the diversification of the economy, delivers increasing prosperity. National identity is embraced, but Indigenous people face racism and discrimination, and their children are removed, creating the stolen generations.
As personal scandal threatens his marriage and looming nuclear war undermines his administration, President John F Kennedy must fight to protect the presidency, the country, and the world.
Visit the Dolphin Research Centre in sunny Florida Keys and its team of volunteers as they look after and educate the wider community about marine welfare and dolphins.
Julia discovers Ukraine's traditional culture, and revisits her own origins. Julia explores the quirkier side of Kyiv, discovering its wide-reaching cultural influences in its food and landmarks. But to really learn about Ukraine's cultural heritage, she attends the Pirogovo Folk Festival at a large-scale outdoor museum.

Sport and comedy offer some relief from the hunger and hopelessness of the Great Depression - at least until war breaks out. Australia sends troops to Europe to fight beside Britain, but when Japan invades Pearl Harbor, the nation turns to America for protection and pulls troops out of the Middle East. Fighting reaches Darwin.
