Deep hole often requires several changes of drill bits. When you drill the bottom of the seafloor, we can use the Advanced Piston Corer (APC) which is used to recover relatively undisturbed sediments from very soft to firm sediments.

The APC is a hydraulically actuated piston corer and it allows to recover continuous 9.5 m samples.
