| Research Abstract |
Near-bottom sediment cores containing gas hydrates were retrieved offshore Sakhalin, Okhotsk Sea and at Lake Baikal. Core analyses were conducted by gas, water and particle measurements to understand the formation and renewability characteristics of gas hydrates. Results obtained reveal (1) characteristics of gas hydrates depending on gas seep activities, (2) fluid seepage types with and without water, (3) carbonate formations due to chemical reactions between seeping gas and sea/lake water and (4) higher renewability potential offshore Sakhalin.
