Abstract
A piston actuated by hydrostatic pressure at ocean depths up to 6 km is used to provide a controlled source of hydraulic fluid at above-ambient pressure. This fluid energy is used to collect box cores of deep-sea sediment and ferromanganese nodules from a free-vehicle instrument platform. At the completion of the coring operation, the same hydrostatically actuated piston is used to release ballast and to extract the vehicle and its cores from the sediment.
