Expedition Deep Ocean

The spectacular record-breaking mission of explorer and entrepreneur, Victor Vescovo, and his Five Deeps Expedition team.

Extreme explorer Victor Vescovo embarks on an unprecedented global mission to dive to the deepest points of all five oceans – a feat no one has ever achieved before.

Vescovo, an ex-naval commander and multi-millionaire investor, funded the entire mission himself at a cost of nearly $50 million. Central to this bold endeavour is a newly-engineered prototype submersible, built to withstand staggering pressures at full ocean depth — the equivalent of being crushed beneath the weight of the US’s largest aircraft carrier.

Embedded with the expedition throughout, this series puts the viewer at the heart of a remarkable story of human endeavour and scientific discovery — from nerve-shredding leaks during the first test dives in the Atlantic, to rough seas and icebergs in the Southern Ocean, diving into a tsunami trigger zone in the Indian Ocean, breaking the world record for the deepest ever dive in the Mariana Trench, and evading floating pack ice to complete the final dive in the freezing Arctic. Over the course of a year-long mission, Victor and his team of adventurers and scientists draw on every reserve of ingenuity and endurance to achieve their dream.

The scientific discoveries are extraordinary. Over 40 new species were identified — from fish with transparent heads in the Pacific to floating balloon-like creatures in the Indian Ocean. Vast swathes of the ocean floor were mapped with cutting-edge sonar in unprecedented detail. And for the first time in history, the series captures footage of hidden landscapes over five miles below the surface — bearing witness to the final, unexplored frontier of our planet.
