Usually found in offshore environments with water depths exceeding about 500 meters and in arctic regions associated with permafrost, gas hydrates form an efficient storage system for natural gas. Hence, they may represent an important future energy resource [e.g.,Kvenvolden,1988]. Gas hydrates also form a natural geo-hazard, and may play a significant role in global climate change [e.g.,Dillon et al.,2001]. Published 15 August 2006.
