Deepest Scuba Dive

Ahmed Gabr's record-breaking 332-meter descent/Human Records & Feats

On September 18, 2014, Egyptian diver Ahmed Gabr set the world record for the deepest scuba dive at 332.35 meters in the Red Sea off Dahab, Egypt. The descent took about 14 minutes, but the ascent required over 13 hours of carefully staged decompression stops to avoid the bends. At that depth, the water pressure exceeds 34 atmospheres, or about 3.4 megapascals. The dive required multiple gas mixtures, including trimix (helium, nitrogen, and oxygen) and pure oxygen for the final decompression stages. Gabr spent 4 years planning and training for roughly 14 minutes of going down.
