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.

Samples were acquired by the scientific drilling vessel JOIDES Resolution at IODP Site U1385A by Advanced Piston Coring (APC).
