The series was announced by the BBC in 2013 with the working title Oceans, but the title was later changed to Blue Planet II as was revealed on 19 February 2017, making it a follow-up to the 2001 series The Blue Planet. ![]() It was credited with increasing public and political interest in issues affecting marine life, in particular marine plastic pollution, which was dubbed "the Blue Planet effect". It had the highest viewing figures of any television programme in the United Kingdom during 2017, and was so widely watched in China that it reportedly caused internet issues. The series received almost universal critical acclaim. In the United States, the series premiered on January 20, 2018, as part of a five-network simulcast on BBC America, AMC, IFC, Sundance, and WE tv. The series debuted on 29 October 2017 and was simultaneously cast on BBC One, BBC One HD and BBC Earth, making it the first natural history series to premiere on the same day in the United Kingdom, Nordic regions, Europe and in Asia. The musical score was composed by Hans Zimmer, Jacob Shea and David Fleming, and English rock band Radiohead reworked their 2011 song "Bloom" with Zimmer specifically for the series. Īfter being announced in 2013, filming took four years in 39 countries over more than 125 international trips. Like its predecessor, The Blue Planet (2001), it is narrated and presented by naturalist Sir David Attenborough. As we begin to understand the true complexity of the lives of our ocean creatures, so do we recognise the fragility of their home.Blue Planet II is a 2017 British nature documentary series on marine life produced by the BBC Natural History Unit. But with rising temperatures, summer sea ice is retreating - their battles to survive are becoming ever harder. Deep in the polar north, we meet walrus mothers and their newborn calves, searching for an ice floe to rest on. But our ocean system, in relative equilibrium for millennia, is changing at a worrying rate. Ocean currents move heat around our planet and maintain a climate favourable for life. Here, in winter, pods of orcas use dramatic tail slaps to stun herring, and humpback whales follow the noises to find the feast. ![]() But in the Arctic, a warm current from the south keeps some Norwegian fjords ice-free all year round. Toward our planet's poles, the ocean's surface is locked in ice. Females change gender, and a new male challenges an older male to a face-off. But when a female reaches both a critical body size and age, it can undergo an extraordinary metamorphosis. At the start of summer a male mates with the females. In Japan, a kelp-covered shipwreck is home to the Asian sheepshead wrasse, or Kobudai. In temperate seas around the globe, spring brings greening oceans. ![]() But when they find them, the whales team up with the dolphins to form super-pods - a formidable army to take advantage of the bounty of these seasonal seas. Predatory false killer whales off the coast of New Zealand are in search of dolphins. Where the plankton thrive, fish thrive too, and ocean travellers will migrate thousands of miles to take advantage of these productive seas. Phytoplankton produce as much oxygen as all the plants on land and lie at the base of marine food chains everywhere. At night, in a previously unseen event, tiny organisms that light up when disturbed react to their wingbeats, creating an enchanting bioluminescent firework display. In spring thousands of mobula rays gather in Mexico's Sea of Cortez. Here, unlike the tropics, the seas change with the seasons. Sun heats the sea, creating rain, winds and huge storms that drive up towards higher latitudes. The tropical oceans drive our planet's weather. Fledglings must eventually take to the wing, but danger lurks beneath the waves - metre-long giant trevally fish leap clear out of the water to snatch the birds. In the Seychelles, half a million terns nest on an island. On another reef, a tusk fish demonstrates a surprising level of ingenuity - tool use - as it uses corals as an anvil to break open clams. Starting in the tropical coral reefs - the most diverse ocean habitat - a baby dolphin is taught the secrets of a coral reef, as its family rubs against a particular gorgonian which may have medicinal properties. Using cutting-edge technology, One Ocean takes us on a journey from the intense heat of the tropics to our planet's frozen poles to reveal new worlds and extraordinary never-before-seen animal behaviours. In recent years, our knowledge of life beneath the waves has been transformed. ![]()
