Abstract :
EPAULARD is designed to conduct deep water bottom photography and topographic proffiling to depths of 6,000 m. It was launched in 1979 and has made 72 dives since that time; 40 of these dives have been to depths between 1,000 and 5,300 m. The vehicle is launched negatively buoyant and, once it has reached a pre-designated height above the bottom, it drops Its descent wefght and becomes slightly positively buoyant. A drag chain holds it a specified distance (3-7 meters) above the bottom, according to the required resolution of the survey data control EPAULARD´s course ts controlled by an acoustick link from the surface. Having completed Its mission, the vehicle drops an ascent weight and returns to the surface.
