Natural gas hydrates occur world-wide in polar regions, usually associated with onshore and offshore permafrost, and insediment of outer continental and insular margins. Three aspects of gas hydrates are important: their fossil fuel resourcepotential; their role as a submarine geohazard; and their effects on global climate change. This book focuses on slope stabilityand climatic issues.
