Fig. 2From: Cool, alkaline serpentinite formation fluid regime with scarce microbial habitability and possible abiotic synthesis beneath the South Chamorro SeamountA 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 lineBack to article page
