There is nowhere more powerful and unforgiving yet more beautiful and compelling than the ocean. Join us and explore the greatest yet least known parts of our planet. “Blue Planet II” explores the latest frontiers of scientific discovery, from icy-white polar seas to vibrant blues of the coral atolls, from the storm-tossed green Atlantic coastline to the black depths of the alien deep. Viewers will encounter surprising new landscapes such as methane volcanoes which erupt in the Gulf of Mexico; and the so-called ‘boiling sea’ phenomenon in the Pacific Ocean. And by taking two manned submersibles to explore the Antarctic deep at 1000m for the very first time, the series will bring a new world to the audience.
