It is demonstrated that microorganisms play a fundamental role on chemical changes of the sediments and diageneses. Over the last twenty years, great interest has been increased about the role of deep-sea bacteria in the ferromanganese sedimentary process.

These paths are divided into 7 categories. The effect of the position and intensity of large- scale wave on each category has been examined. It has been discovered, as a result, that this effect is rather evident. On the other hand, the teleconnection between different centers of anion does exist. A simple theoretical analysis indicates that the teleconnection is related to the propagation of wave energy. Thus, to predict correctly typhoon path, not only the steering flow of typhoon, but also, more significantly, the behavior of large-scale wave over the Northern Hemisphere must be taken into consideration.展开更多
