A total of 614 sediment samples at an interval of about 1.5m from all 5 sites of the Integrated Ocean Drilling Program Expedition 311 on Cascadia Margin, northwestern Pacific were analyzed using a Beckman Coulter LS-230 Particle Analyzer. The grain-size data were then plotted against depth and compared with other potential proxies of gas hydrate-occurrence such as soupy/mousse-like fabrics in sedimentary textures, gas hydrate concentration S(subscript h derived from LWD data using Archie's relation, IR core images and the recovered samples of gas hydrate-bearing sediments.
