BBC America is following up on its success with Planet Earth II.

According to The AV Club BBCA has announced Blue Planet II, a follow up to the Emmy-winning 2001 documentary series. It is set to be seven parts and will once again be presented by Sir David Attenborough as he narrates the wonders of the Earth’s oceans.

“I am truly thrilled to be joining this new exploration of the underwater worlds which cover most of our planet, yet are still its least known,” said Attenborough.

Blue Planet II will cover everything ocean-related, from Hoff crabs and snub fin dolphins to methane volcanoes and the “Boiling Sea” phenomenon. The series will take advantage of new UHD tow cams and suction cams in order to get new angles on large creatures like whale sharks and orcas. The first Blue Planet series was nominated for five Emmys and won two, including one for Outstanding Cinematography for Non-Fiction Programming.

“Hot on the heels of a rapturous response in the US to Planet Earth II, we are delighted to announce our next, phenomenal and beautiful series from the BBC Natural History Unit, Blue Planet II,” said BBCA President Sarah Barnett. “Like Planet Earth II, this is a remarkable and relevant sequel — this time plunging us into an awe inspiring trip into our planet’s oceans — that will stand out as rare and extraordinary, even in today’s superlative TV landscape.”

Blue Planet II comes from BBC Studios Natural History Unit, BBC America WDR and France Télévisions.
