ODP Technical Note 10
VII. PRESSURE CORE SAMPLER
The pressure core sampler (PCS) is fully described in ODP Technical Note 17 (Pettigrew, 1992), from which the following material was excerpted. The PCS was developed by T. Pettigrew at ODP as a replacement for the pressure core barrel designed during the Deep Sea Drilling Project (DSDP). Development of the PCS resulted largely from interest in improving recovery and maintaining stability of gas hydrates. The stated goal for Phase I of the PCS was to develop a prototype that could demonstrate and test the concept of improved techniques for obtaining pressurized core, gas, and water samples at near in-situ pressure. This effort has been partially successful, as revealed most recently during Leg 146, but additional refinement is needed.
