1962Conshelf I — Albert Falco and Claude Wesly became the world’s first multi-day aquanauts by spending seven days in the Diogenes habitat at a depth of 10 m (33 ft). They were also the first aquanauts to live on the seafloor. The experiment supervised by Jacques-Yves Cousteau off the Frioul Archipelago near Marseille began on September 14. Falco and Wesly spent an average 19 hours inside the habitat and five hours on scuba conducting various assignments. The breathing gas was air. The experiment was known in French as Précontinent I.

Conshelf I took place only one week after Robert Sténuit became the world’s first aquanaut.
