For the discovery of the San Diego, Franck Goddio's team used a catamaran called "Kaimiloa."

ELECTROLYSIS
A process using an electric current which eliminates some kinds of encrusted substances from metal objects. The object immersed in the electrolytic liquid works as a negative electrode (cathode), while a stainless steel net around it is used as a positive electrode (Anode). The continuous current circulating within this "electrolytic cell" causes reactions that free the metal object from its matrix.

MAGNETOMETER
An instrument used for measuring the intensity of magnetic fields.

NARGUILE
Flexible tubes allowing divers to breathe either air or oxygen at a depth of less than 9 meters.

NUCLEAR MAGNETIC RESONANCE
Uses the characteristics of the nucleus of the atom, in which particles rotate around their own axis, to make observations about their environment. When excited with a strong magnetic field, they emit a signal that allows these observations to be made.

DECOMPRESSION
Air and oxygen lines are put in place to resupply the divers during the decompression stages. While working time at the bottom of the ocean lasts from thirty to forty minutes, the divers must spend nearly one hour in decompression before coming up to the boat. Trapezes allow them to sit comfortably, for these waits are long. Sometimes, the divers while away their time with games or reading!

DECOMPRESSION CHAMBERS
In order to calculate the duration of these stages, the diver uses decompression tables. The timing of the stages varies in relation to the depth reached and the duration of the dive. In order to shorten decompression times, the stages at nine meters and six meters are fed in pure oxygen.
