Deep Ocean

Giants of the Antarctic Deep (1x4)

:

The world's first scientific dive in icy polar waters The NHK team behind the world's first footage of a live giant squid in its natural habitat follows three marine biologists as they venture into the deep sea of the Antarctic. Equipped with custom 4K UHD cameras, the team will embark on the world's first scientific research by a submersible in the Antarctic. The dive in the Southern Ocean reveals a surprising world of bountiful marine life, where many creatures are gigantic forms of their shallow-water-dwelling relatives. A hostile, inaccessible world locked away under ice and snow permits us the first vivid glimpse of its long concealed secrets. Narrated by Sir David Attenborough.
