Scientists from AIST, JOGMEC, Georgia Tech, and the USGS prepare to analyze pressure cores as part of a multi-year gas hydrates research project in Japan. This photo shows the pressure core storage chambers, which contain hydrate-bearing sediment samples obtained from the Nankai Trough offshore Japan. The orange and blue “cart” on the left side and center of the photo is used to safely move the cores from refrigerated storage to the test facility. Ball valves, located on the bottom of the storage chambers, allow the sediment cores to be transferred under pressure into other test devices.
