CBC: One Ocean Episode Rating Graph

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?

In our final episode, The Changing Sea , we discover that the ocean is sending us clear signals. Off the rugged and beautiful coast of British Columbia we meet scientists and fishermen who are shocked at the recent arrival of a voracious new creature – the Humboldt squid. This monster-sized squid native to the equatorial waters of Mexico has moved north and ushered in a cascade of changes to the ecosystem. Their arrival is part of a disturbing pattern that is emerging with species movement being tracked around the world. In The Changing Sea we illustrate how the ocean’s chemistry and systems are being compromised by increased acidity, less oxygen and warming temperatures. The changes to the timeless rhythms of birth and renewal are being felt everywhere – even on coral reefs. In the idyllic waters of the Bay of Naples, we get a glimpse of our future ocean, thanks to the mythic Mount Vesuvius. As scientists swim through lush green seagrass beds, they collect creatures whose shells are dissolving, and we discover that this amazing place has a terrible secret. It has been naturally acidified for millennia – could this be our ocean’s future? Our guides to the hidden depths of the sea are some of the planet’s most innovative and charismatic marine scientists, and the people who live and die by the sea. Fast-paced and engaging, the series is visually stunning, and gives viewers a deeper understanding of the Ocean’s unbelievable complexity. Our telling of the journey mixes powerful animation, special effects and striking pictures shot in HD. The visual beauty and style of this series gives audiences an emotional connection to the past, present, and future of the ocean. Compelling experiences shared with dedicated and passionate scientists connect audiences intellectually to the beautiful symmetry that exists within its depths. One Ocean captures a fragile, interconnected world that knows only one constant: change. It is a world that we could not exist without.
