What to remember
In 1988, in the Mediterranean, a team of COMEX and French Navy divers worked at a depth of 534 m, or 1,750 ft. This was not exploration: they were carrying out pipeline connection exercises.
The operation was part of the Hydra 8 programme. The divers breathed heliox and hydrox; in deep diving, a hypoxic breathing gas is required below 60 metres.
The record is for open-sea diving. It shows deep diving in its professional form, far beyond recreational limits, where a "deep diver" certification usually means training for depths beyond 30 metres.
