DEEP OCEAN: GIANTS OF THE ANTARCTIC DEEP

BBC Four, 9.00pm

There are few TV sounds more soothing than the awed tones of David Attenborough. In these tumultuous times, his hushed narration is even more welcome to hear. It comes as a treat, then, that the 94-year-old natural historian has voiced this visually stunning documentary about the first scientific research undertaken in a submersible in the Antarctic.

Three Japanese marine biologists use customised 4K ultra-high definition cameras to explore the cryptic depths of the Southern Ocean and capture the bountiful marine fauna that thrives there. As a result of their adaptation to the coldest place on Earth, some species have evolved into gigantic forms of their shallow water-dwelling relatives. Many of these monstrous creatures are new to science and astonish the expedition crew with their sheer size. There’s a surprising, spectacular world hidden beneath that hostile ice and snow – it rivals the coral reef for colour, variety of life forms and vast swarms of fish. Who better to accompany us there than the venerable Attenborough? It’s followed by reruns of two more underwater documentaries. Sink into a peaceful evening of sub-aqua programming. Michael Hogan
