Characteristics of hydrate-bound gas retrieved at the Kedr mud volcano (southern Lake Baikal).

We reported the characteristics of hydrate-bound hydrocarbons in lake-bottom sediments at the Kedr mud volcano in Lake Baikal. Twenty hydrate-bearing sediment cores were retrieved, and methane-stable isotopes of hydrate-bound gases (δC and δH of - 47.8‰ to - 44.
