Water and natural gas, under certain conditions of temperature and pressure, can form naturally occurring gas hydrates in sediments that underlie ocean basins and permafrost regions. Hydrates have been identified in the offshore environment during drilling and coring of certain formations. However, normal sampling of seafloor sediments has not always revealed their presence, because they invert to free gas and dissipate during transport to the surface. Geophysical and geochemical techniques may provide the answer to the detection of hydrates in ocean sediments and allow a more detailed determination of the volume of hydrates within the sediments. While there has been research directed toward the understanding of both surface and subsurface geophysical techniques and their relationship with gas hydrate formations, the work is in preliminary stages of understanding and development. This paper will attempt to summarize the problems related to the detection of gas hydrates; identify some promising research in both geophysical and geochemical methods which may provide better, more reliable detection techniques for identifying gas hydrate deposits; and attempt to indicate the areas where more research is needed.
