A total of 614 sediment samples at an interval of about 1.5 m from all 5 sites of the Integrated Ocean Drilling Program Expedition 311 on Cascadia Margin, northwestern Pacific were analyzed using a Beckman Coulter LS230 Particle Analyzer. The grainsize data were then plotted against depth and compared with other potential proxies of gas hydrateoccurrence such as soupy/mousselike fabrics in sedimentary textures, gas hydrate concentration derived from LWD data using Archie's relation, IR core images and the recovered samples of gas hydratebearing sediments.
