Book Description
By examining the relationship of the individual waves in an ocean wave record and the power density spectrum (PDS), it is demonstrated that the PDS conventionally obtained using spectral analysis can be reasonably approximated, except at the very low frequency end, by a pseudo-power density spectrum constructed from the individual heights and periods contained in the record. The very low frequencies seen in the side bands of the PDS are examined as products of amplitude modulation by analogy with simulated wave records and as an indication of the presence of wave groups. In addition, wave groups are identified and their properties determined in 19 selected ocean wave records by integrating the wave record using the procedure of Funke and Mansard (1979). (Author).

Book Description
A computerized method for the identification of wave groups and determination of their properties from digital wave data was developed. Analysis was performed on 208 Southern California wave records. It was found that the number of waves in a group is independent of both the spectral peak period and the variance of the wave record. However, the amount of energy contained in wave groups relative to that in the record increases as the total energy of the record increases. Also, average group periods of greater than the spectral peak period are not uncommon. Both an increase in group energy relative to the wave record and also the number of waves in a group increase the possibility of obtaining an extreme wave height in a group relative to the significant wave height of the record. Finally, it is apparent that as the average group period approaches the spectral peak period of a record, all other highly dependent wave group properties take on their maximum values. (Author).

Book Description
The purpose of this book is to provide the information required for understanding the fundamental aspects of the elaborate computer processing schemes prevalent in exploration geophysics. Basic Wave Analysis has three parts. Part 1 addresses velocity analysis. The correct determination of velocity is the most important problem in seismic exploration, and an understanding of velocity analysis is a valuable asset for a geophysicist. Part 2 discusses raypath analysis. Raypaths provide a geometrical picture of how waves travel, so that a person can visualize raypaths in their imagination. Geometrical pictures are as important in seismology as they are in optics. Part 3 addresses wavefront analysis. A person cannot easily visualize traveling wavefronts in their imagination; however, a computer can follow their motion, and give the geophysicist the final outcome. Knowledge of wavefront analysis helps a geophysicist understand many modern computer methods. This book has not been written to address advanced subjects. Rather, it concentrates on the basic concepts of Fermat and Huygens to explore and understand basic wave analysis. This book is based upon inventive science. It deals with ideas, and not with numerical algorithms. It does not explain the details the many migration and inversion methods use, but it does provide readers with the tools needed to make those topics more understandable. The three parts of this book are in the order of increasing difficulty, and the most important part is Part 1, because velocity analysis is central to every seismic investigation.
