You are inside the spherical cabin of a Mir submersible, descending into a mysterious new world. Above you is a mile of ocean; the distant seafloor is a mile and a half below.

It is dark outside the sub, but a fireworks display of twinkling blue lights dances outside your viewport. What are they? Your Russian pilot smiles and switches on the exterior lights, revealing the ethereal forms of myriad glowing creatures. Your jaw drops: so this is where science fiction writers get their ideas!

Welcome to the Deep. You are entering a place few have seen, a realm of mysterious seascapes, alien creatures and lost monuments to past civilizations. Here depth is measured in miles, not feet. Far beyond the reach of scuba divers, this dark wilderness is accessible to only a handful of specialized craft.

You are here to explore. The Deep is Earth’s last frontier, the last place to retain its mystery and isolation in an age of information and overpopulation.

Every submersible dive reveals something new and your journey will forever transform your view of the planet you live on. No matter what you have done, or where you have travelled, you have never experienced anything like deep-sea submersible diving – and we’ve been told that by astronauts!

We invite you to join us on an unforgettable adventure.
