Instrument: Advanced Piston Corer
The JOIDES Resolution's Advanced Piston Corer (APC) is used in soft ooze and sediments. The APC is a hydraulically actuated piston corer designed to recover relatively undisturbed samples from very soft to firm sediments.
More information is available from IODP (PDF).
All samples described in this study were collected using an advanced piston core, a tool that minimizes core disturbance.
