Tulum, Mexico. Hidden amid a dense, tropical forest, a seemingly ordinary lake appears. Two heads are sticking out. Maria Bollerup and Rannvá Jørmundsson exchange a few last nods, ensuring each other they’re ready for what’s to come. Then they disappear. While that lake looks unsuspicious from above, it actually hosts a whole new world to explore. If you only know where to look — below the surface.

Let’s zoom out for a moment.

Humans have a desire to explore, but what about the Ocean?

Did you know that 80% of the underwater realm and 90% of all underwater caves still remain unexplored? 

We reached the deepest spot on Earth, the Mariana Trench, and have climbed the highest summits Mount Everest has to offer. We’ve been to the moon, and now we even dream about colonizing Mars. As NASA puts it: “Throughout history, humankind has shared an innate trait – the desire to explore.”

Yet, why are we so shy to shed light on what is covering 71% of the Earth’s surface, our Oceans? 

After disappearing into the lake, Maria and Rannvá need to pass the first restriction of the cave to access further. It’s muddy and dirty, and it’s hard to see your own hands, let alone your surroundings. However, both keep their calm and concentration. 

Why technical divers are at the forefront of ocean exploration

Maria and Rannvá are technical divers and therefore specifically trained to dive underwater caves such as the Tortuga Cave. They especially want to encourage women to pursue technical diving. To put it in Rannvá’s words: “This is the most awesome thing that you can do!

Scientists agree. Technical cave divers are at the forefront of ocean exploration, as they can access some of the deepest and darkest water-filled parts of our planet. Understanding more about underwater caves allows us, for example, to gain a better understanding of the evolutionary history of life on Earth. 

The only way to find out what’s in there is actually by going and looking.

UNEXPLORED: What will you discover?

Watch our short film UNEXPLORED to find out what Maria and Rannvá experience, after passing the first restrictions and the Tortuga Cave opens up. Maria and Rannvá also talk about how they challenge their fears and how technical diving enables you to become an explorer of the unknown.

What will you discover?

UNEXPLORED is not only a short film about ocean exploration. It is a statement for ocean awareness, inviting each and everybody to become ambassadors of the Ocean. A statement for collaboration to align our priorities under a shared vision. And, a statement for inclusivity, to shatter the misconception that cave diving is reserved for men. 

UNEXPLORED is the first outcome of a new partnership by five of scuba diving’s leading brands. The collaborating brands are Apeks, fourth element, IQSub, Paralenz, and Shearwater Research.
