A schematic illustration and photographs of the “Deep Sampler” used for CORK fluid sampling. a The open titanium bottle, chamber, and valve units were lowered to the screened depths (170 mbsf) through the cased hole. Then, a messenger weight was dropped from the seafloor along the rope, resulting in closing the bottle unit to the chamber-valve unit for fluid sampling. b A photograph showing the Deep Sampler being prepared in the payload of the ROV Hyper-Dolphin. c A photograph showing the on-site operation of the Deep Sampler from 170 mbsf by manipulation of reeling in the support line
