Looking for something to do post-holiday, but it’s still too cold for the beach? Come explore the oceans at Damariscotta’s Lincoln Theater. Every Saturday morning through January, following on last year’s successful showings of season one, the Lincoln Theater will be screening, for free,  all seven episodes of the BBC’s “Blue Planet 2.”  This landmark nature series exploring the world’s oceans and narrated by world-renowned broadcaster and naturalist Sir David Attenborough, returns to these underwater worlds to immerse the audience in some of the most expansive but least well know parts of our planet.

“Blue Planet 2” 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, as well as astonishing new creatures, including hairy-chested Hoff crabs; snub fin dolphins that spit water through the air; and Pacific leaping blennies, that have now been filmed for the first time, and extraordinary examples of behavior, such as sophisticated hunting between a coral grouper and a reef octopus; giant trevally that catch flying birds in mid-air; and a dive with a sperm whale mother and calf, as she heads deep in to the abyss to hunt.

The series’ camera teams have worked on every continent, and across every ocean. They have developed new filming technologies, including UHD ‘tow cams’ that allow predatory fish and dolphins to be filmed front-on; UHD suction cams which enable the viewer to ‘travel’ on the back of large creatures such as whale sharks and orcas; and a motion control rig, which is used to shoot time-lapse footage in the ocean, to reveal previously unseen wild behaviors.
