A new series of The Blue Planet featuring naturalist Sir David Attenborough’s voiceover will air later this year on BBC.

BBC has announced that the exploration of the world’s seas will include animals never filmed before, as well as footage from 1,000 metres under the Antarctic Ocean.

The original 2001 series received wide critical acclaim, winning two Emmys and two Baftas for its music and cinematography.

David Attenborough, who turned 90 last year, is known for a career in nature documentaries spanning over 50 years.

The second series of The Blue Planet will follow the highly successful Planet Earth 2, which aired in the UK last year. It was the most watched natural history programme for 15 years, according to the BBC.
