Geochemical Analysis as a Complementary Tool to Estimate the Uplift of Sediments Caused by Shallow Gas Hydrates in Mounds at the Seafloor of Joetsu Basin, Eastern Margin of the Japan Sea

Figure 3

Gas hydrate-bearing sediments collected by piston cores in Joetsu Basin. Blocky- and fracture-filling gas hydrate can be observed. Both nondisturbed and soupy sediments disturbed during piston coring were sampled and analyzed to compare with nondisturbed sediments collected far from mounds.
