Episode Three of our series reveals the Mysteries of the Deep and takes us to the most beguiling parts of the sea, the very depths that we know so little about. As we improve our technological prowess, we are venturing deeper and deeper into the planet’s last frontier. What scientists are discovering is beyond our wildest imaginings. We join a team of scientists, ranging from biologists to vulcanologists, on an international expedition as they return to the Mariana Arc, on the Pacific Rim of Fire. As their submersible ROV plumbs the depths of the ocean, the thrill and excitement of peering into these extreme environments is palpable. Each day they make new discoveries about the outlandish deep-sea dwellers they find here. But at the same time that we begin to unravel their mysteries we’re also mining the sea of many species. Finally Mysteries of the Deep asks the question: can cutting-edge technologies allow us to truly experience, for the first time, the three-dimensional world of the deep ocean?
