This paper presents a general review of gas hydrate knowledge, the utilization of such knowledge in the natural gas industry, some contemplated uses of gas hydrates in sea water desalinization, and discusses the existence of natural gas hydrates under the permafrost of the Northern Hemisphere. The theory of how gases enter the water phase and cause premature crystallization of water into an ice-like hydrate structure is presented. With this background, hydrate formation in ocean sediments is considered.

In the present investigation, we have carried out power spectrum analysis of sunspot number and great hard X-ray (GHXR) burst (equal to or greater than i0,000 counts per second) for a period of about 6 years. The GHXR bursts show a periodicity of about 155 days. On the other hand, sunspot numbers do not show any periodicity. The GHXR burst periodicity confirms the existence of a 152-158 days periodicity in the occurrence of solar energetic events. Further, the GHXR bursts are showing periodicity independently indicating that the GHXR bursts are a separate class of X-ray flares.
