BBC has tapped veteran English broadcaster and naturalist Sir David Attenborough to return for the sequel to 2001's Blue Planet. The seven-part series will thus be arriving later this year, highlighting various scientific discoveries. You can look forward to such filming innovations as cameras positioned on the backs of magnificent orcas, as well as "tow cams" that can capture predatory fish and dolphins head-on.

"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," Attenborough revealed.

Blue Planet II was filmed over a four-year period, with visits to every continent and ocean. The series' executive producer, James Honeyborne, insists, "The oceans are the most exciting place to be right now, because new scientific discoveries have given us a new perspective of life beneath the waves."

He then went on to add: "Blue Planet II is taking its cue from these breakthroughs, unveiling unbelievable new places, extraordinary new behaviors and remarkable new creatures. Showing a contemporary portrait of marine life, it will provide a timely reminder that this is a critical moment for the health of the world's oceans."

You can look forward to Blue Planet II coming to BBC One later in 2017.

BBC is also scheduled to bring black Planet Earth in a major way. See below.
