Materials of the World Data Center B. Deep Seismic Sounding (DSS): Pacific Data

摘要

The catalog contains results obtained by the method of deep seismic sounding in the Pacific Ocean in experiments begun in 1948 to 1950 and then continued into the early 1980's. The tables of velocity values and thickness of Earth crustal layers, the parameters of the M boundary as well as schemes of seismic sections for more detailed studies are presented. The tables are compiled on the basis of previous publications and available summaries. The distinctive feature of the catalog is that the tables give the information based on observational methods. To demonstrate, the legend chosen on the basis of the analysis of the system of travel-time curves, and the characteristics of sources and receivers are taken into account. This approach allows the scientists to evaluate the relative reliability of each section. The peculiarities of the method are indicated in the study map showing the areas of investigations.
