Figure F53. Summary of data collected from PCS cores at Site U1328, including gamma ray density scans collected during degassing, X-ray images collected before degassing, line scan images collected after degassing, and chlorinity data collected in selected zones. Gamma ray density scans are shown as differential density plots (i.e., as profiles from which the initial profile has been subtracted). A. Core 311-U1328B-4P. Arrows point to presumed gas hydrate veins imaged before depressurization and the gas voids they created after depressurization. (Continued on next four pages).
