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 2

Structural-stratigraphic control on the gas hydrates of Umitaka Spur. Arrow size suggests the intensity of gas migration. The combination of the shape of the anticline, carrier beds, and the axial fault system induces gas migration to the top of the structure supplying gas for the GHSZ and to the water column forming giant plumes. See profile location in Figure 1. This model was modified from Freire et al. [11].
