Abstract
A compensator added to the hydraulic circuit of an ocean profiler. The compensator stores energy by compression of gas during descent and expansion of the gas during ascent, thereby reducing the work required of the active buoyancy mechanism. The pressure from the external liquid medium in which the vehicle is submerged provides the energy, a portion of which is stored within the compensator.
