Deep Ocean: Giants of the Antarctic Deep
BBC IPLAYER, STREAMING NOW
“It’s the coldest place on Earth. A world locked away under snow and ice. So hostile and inaccessible, it has long concealed its secrets from us.” A mysterious start to this new BBC Four documentary, narrated by David Attenborough. This programme follows the journey of a scientific expedition on MV Alucia, exploring the icy waters around Antarctica. On average, the ocean here measures between 4,000–5,000m in depth, so the team must use deep-sea submersibles that can carry passengers and descend to 1,000m – the first time this has been done here. The dives reveal a diversity of extraordinary creatures, many of which are new to science. They also find astonishingly large species, a phenomenon known as polar gigantism, including squids and jellyfish.
