The story behind Diver`s cemetery

“The Blue Hole” in Dahab.

The Blue Hole in Dahab, South Sinai is a world-renowned dive site also known as the Diver`s Cemetery.

Due to its depth and topography, some scientists claim that the Blue Hole was formed by a direct hit from a meteorite. It’s a submarine sinkhole, around 94 meters deep (300 feet) with a shallow opening around 6 meters deep known as The Saddle which opens out to the sea.

A 26-meter long tunnel, known as The Arch, at a depth of 56 meters (184 feet), connects the hole with the open sea. The Blue Hole and its surrounding areas have an abundance of coral and marine life. Beyond it the sea is open and deep, starting at a depth of 110 meters.

300 meters north of the Blue Hole a crack in the reef plateau, known as El Bells, is accessible from the shore. It descends to 31 meters (90 feet) with rocky walls and a chimney from 24 to 28 meters. Divers tanks keep banging on the walls due to the slim-fitting of the chimney during descent and make the sound of bells.

Diving Techniques and Gases Used in The Blue Hole

Recreational Diving: This is basic SCUBA diving with a tank filled with compressed air. Recreational divers use only one tank per dive and are limited to a maximum depth of 30 meters/90 feet. Beyond that, the air will become affected by pressure depth that may cause unconsciousness which leads to death.

Technical Diving: Diving with a mix of gases called TRI-mix that contains oxygen, nitrogen, and helium. Technical divers dive with several tanks requiring special and intense training as the percentage of each gas within the mix depends on the depth and period of each dive as a separate profile.

Safe Diving Behaviors: These include points stated by PADI and other diving organizations:

  • Stick to your training and maximum depth limits.
  • Always dive with a buddy.
  • Plan the dive with your buddy or your dive guide and stick to your plan.
  • Maintain and service your diving equipment regularly.
  • Avoid diving if you’re not feeling well.

Good to mention that most diving accidents within the Blue Hole occur due to human error. Only a small percentage are attributed to natural causes.

One incident involves Yuri Lipski, an Israeli-Russian diving instructor, who died at just over a hundred meters (300 feet) underwater. At this depth, the body is subject to nitrogen narcosis which leads to overconfidence, euphoria, hallucinations, confusion, and impaired judgment.

Technical divers are better served by multiple tanks filled with tri-mix. Lipski had just one tank full of air.

When Tarek Omar, regarded as the father of technical diving, retrieved Lipski’s body at the request of his parents, he found that footage captured by Lipski’s helmet camera was still intact.

Lipski’s final six minutes are on YouTube entitled, Fatal Diving Accident Caught On Tape.

Regardless of its dangers, Blue Hole is a must-dive site on any diver’s list. At Sinai Gate, we call it the Space Dive where you follow your guide, adjust your buoyancy, and fly endlessly into the blue without gravity, from El Bells to the Blue Hole.

Special Thanks to Tarek Omar, who gave us very useful info & support
