A pair of extreme athletes has executed a "world’s first" – death diving (aka dødsing) off a staggering 65-foot glacier in the freezing wilds of Greenland.

The radical stunt was pulled off by the notorious Norwegian extreme sports crew known as 00Nation. For their biggest challenge yet, the squad traveled deep into the Arctic to scout the ultimate launchpad: a pristine, unstable, and potentially shifting ice cliff towering over the near-freezing polar waters.

Take a peek below.

“We are in Greenland,” one of the crew says. “This is where all the icebergs are located. I’m big time nervous for this project. That’s how it’s supposed to be. Gets you focused. Gets you ready. Time to break history. Nobody has ever done this before.”

Typically, the global surfing community looks at Greenland’s massive glaciers from a completely different angle. Novelty-wave hunters wait patiently along the shoreline for these massive ice shelves to break apart, or calve, which pushes out a heavy displacement wave that can be surfed for miles.

However, the 00Nation crew flipped that script entirely, using the treacherous face of the active glacier as a dizzying, high-stakes platform.

Instead of riding the resulting wave, they threw themselves headfirst into the sport of "dødsing"—internationally known as death diving. Originated in 1972 at the Frognerbadet open-air pool complex in Oslo, Norway, the extreme discipline was pioneered as a playful stunt among local youths to test their bravery from the 10-meter tower.

The mechanics of a proper death dive are simple yet terrifying. Divers launch themselves from high cliffs or platforms and hold a completely flat, horizontal spread-eagle or "X" posture mid-air, making it look as though they are about to execute a catastrophic belly flop.

At the absolute last millisecond before breaking the surface, the diver must rapidly tuck into a tight pike position, absorbing the immense water impact safely with their hands, feet, or knees.

What began as a localized Norwegian pastime has boomed into a massively popular global phenomenon. Backed by the International Døds Federation, the sport now features a global world tour, packed stadiums, and millions of viral views.

Yet, taking this high-impact landing technique out of controlled pools and hurling it off a moving, 65-foot wall of Arctic ice is a different beast entirely, cementing 00Nation’s place in extreme sports history.

“Crazy good feeling,” the boys exclaimed after the historic døds.
