Conshelf III | Précontinent III | 1965 (France) — A team of six Cousteau divers spent 22 days at 100 m (328 ft) in the Mediterranean Sea off the coast of southern France (Île du Levant). The two-level spherical habitat weighed 140 tons and had a diameter of 6 m (20 ft). The divers breathed a gas mixture of 98% helium and 2% oxygen for the duration. The team of aquanauts consisted of André Laban, Philippe Cousteau, Jacques Rollet, Christian Bonnici, Raymond Coll and Yves Omer.
Conshelf III was not the world’s deepest underwater habitat.
