Following on last year’s successful showings of season one of the BBC’s “Blue Planet” series, Lincoln Theater in Damariscotta will be screening, for free, all seven episodes of “Blue Planet 2” on Saturday mornings from January 5 to February 2. The nature series explores the world’s oceans and is narrated by broadcaster and naturalist Sir David Attenborough. In “Blue Planet 2” viewers will encounter new landscapes, as well as new creatures, including hairy-chested Hoff crabs, snub fin dolphins that spit water through the air, and Pacific leaping blennies that have been filmed here for the first time. The series’ camera teams have worked on every continent and across every ocean and have developed new filming technologies, including UHD “tow cams” that allow predatory fish and dolphins to be filmed front-on; UHD suction cams that 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. The schedule is as follows: on Saturday, January 5, episode 1, “One Ocean,” at 10 a.m. and episode 2, “The Deep,” at 11 a.m.; on Saturday, January 12, episode 3, “Coral Reefs,” at 10 a.m.; on Saturday, January 19, episode 4, “Big Blue,” at 10 a.m. and episode 5, “Green Seas,” at 11 a.m.;  on Saturday, January 26, episode 6, “Coasts,” at 10 a.m. and episode 7, “One Blue Planet,” at 11 a.m.; and the final episode from season 2, “Oceans of Wonder,” at 9:30 a.m. on Saturday, February 2. Additional information can be found on the theater’s website,
