North Atlantic: The Dark Ocean

North Atlantic: The Dark Ocean follows underwater cameraman Ken O'Sullivan into the cold, mysterious depths off Ireland's coast. The film encounters orcas, sharks, jellyfish, and other marine life rarely captured on camera in these waters. Inspired by the wildlife of the North Atlantic, its 4K footage brings the dark sea vividly to life. Beautiful and immersive, it reveals an ocean far richer than it first appears.
