Man has gone to extreme measures to deepen their knowledge of our oceans. One way we’ve done this is through deep dives – something PADI defines as at least 18 meters down. For our purposes, we’ve listed some of the most memorable deep dives on record. Some of these are scuba, others inside a vessel, others…
World Record Deep Dives
Free Dive: Herbert Nitsch
Free diving is crazy impressive if you ask me.
Without any breathing apparatus, you’re swimming into the depths with only one breath to keep you oxygenated.
On June 6, 2012, Herbert Nitsch, a free diver holding over 30 world records, descended 253 meters in Greece. At the last 10 meters down, he experienced an overwhelming amount of decompression sickness and was aided by medical divers nearby. Still, this record is unbelievable, especially considering the amount of stress and pressure on his body.
Here’s a video of his previous record in 2007:
Vessel Dive: James Cameron
Most people know him as a movie director of Titanic.
But James Cameron has some other credits to himself, in this instance, the first person to reach the bottom of the 6.8 mile Mariana Trench alone. He’s had a fascination with ocean depths for many years, made especially evident in The Abyss. Cameron successfully reached and analyzed one of the deepest parts of the ocean with his special submarine, “The Challenger.” He stayed at the bottom collecting data for about three hours before coming back to the surface.
Scuba dive: Ahmed Gabr
First of all, we want to give respect where it’s due: Dr. Guy Garman, one of the most knowledgeable technical divers of our time, passed away in an attempt at the latest deep dive in 2015. You can read more about it here.
These are actually called “ultra-deep” dives, in which divers attempt to break the record. The latest broke the last record by almost 15 meters: 332. Ahmed, an Egyptian, dived into South Sinai with a support team of 24 trainers, divers and medical and communication support.
It took him four years of intensive mental and physical training to reach his goal. In fact, he wanted to complete it in 2012, but due to the politically tense situation in his mother country, he delayed his champion dive. He was both a scientist and diver, studying the effects of nitrogen narcosis and many other decompression related issues that can surface when diving to extreme depths.
When it came down to it, he realized that the only way to fully understand it was to use his own body as a guinea pig of sorts.
This he did – successfully.
