Abstract:
The pressure core sampler (PCS) is a tool designed to recover a 1385 cm**3 cylindrical sediment core at in situ pressure (Pettigrew, 1992). Quantity and composition of gas in a sediment sample at depth can be determined by releasing gas from the PCS at the surface. Shipboard data collected from PCS deployments on Leg 164 are of great interest to the scientific community because they provide the only direct information concerning in situ gas quantities and composition in deep-sea sedimentary sequences (Dickens et al., 1997, doi:10.1038/385426a0). A portion of total data collected from the PCS was published in "Downhole Tools and Sampling" sections of site chapters in the Leg 164 Initial Reports volume (Paull, Matsumoto, Wallace, et al., 1996, doi:10.2973/odp.proc.ir.164.1996). Here we present the shipboard PCS data not included in the Initial Reports volume because of time constraints. Suggested improvements for future PCS data collection also are noted here. Interpretations based on PCS data are discussed elsewhere in this volume and by Dickens et al. (1997, doi:10.1038/385426a0).

Comment:
Sediment depth is given in mbsf. Some pressures are different than those reported by Paull, Matsumoto, Wallace, et al. (1996, doi:10.2973/odp.proc.ir.164.1996). The reason is twofold: pressure changes rapidly over the first minute, and certain pressures were recorded by more than one individual. Recovered pressure was originally given in psi and was recalculated to bar by multiplying by 0.06894757.
