Offshore methane hydrate assessment and evolution with novel geophysical methods

点击翻译按钮获取中文摘要

Methane clathrate hydrate is a solid compound of water and methane. It has been discovered by drilling and integrated geophysics beneath the sea floor in water depths exceeding 500m off the west coast of Vancouver Island. Hydrate has even been trawled to the surface by fishermen. Worldwide, similar deposits are estimated to contain an amount of hydrocarbon that exceeds the sum in all other known reserves. The material may well become the clean burning fuel of this century. Methane is also a powerful greenhouse gas. It is clear that the detection, evaluation and long term monitoring of deposits is of importance, not only to determine the resource value but also for natural hazard and environmental assessment.
