Outline of Final Research Achievements

Four field investigations were conducted using research vessels to study subsurface gas hydrate formation at Kukuy canyon in Lake Baikal during four years of the present study. Subsurface sediment cores were retrieved by using gravity corers from characteristic areas such as mounds and mud volcanoes. Total seventeen subsurface gas hydrate-bearing sites were discovered in the studied areas. The experimental results from chemical analyses using gas, sediment pore water and dissociated gas hydrate water samples as well as geotechnical analyses of the retrieved sediment cores show characteristic environments for the formation of gas hydrates in the studied areas.
