Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

Book excerpt: The paper presents a summary and history of the wave recording program at the Coastal Engineering Research Center (CERC) and its predecessor, the Beach Erosion Board (BEB). There is a brief description of the types of sensors and recorders that have been used, and of the methods of analysis utilized. The main body of the paper is a listing of the wave gage stations, their locations, date of establishment, equipment used, present status, and periods of time over which records and analyses have been made. This listing is followed by a list of stations which have supplied visual-observation records in a program made possible by the cooperation of the United States Coast Guard. The location of each station is given along with the date of establishment, present status, and periods of time for which observations have been made. (Author).

Download or read book Surface Wave Analysis for Near Surface Applications written by Giancarlo Dal Moro and published by Elsevier. This book was released on 2014-11-04 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic Wave Analysis for Near Surface Applications presents the foundational tools necessary to properly analyze surface waves acquired according to both active and passive techniques. Applications range from seismic hazard studies, geotechnical surveys and the exploration of extra-terrestrial bodies. Surface waves have become critical to near-surface geophysics both for geotechnical goals and seismic-hazard studies. Included in this book are the related theories, approaches and applications which the lead editor has assembled from a range of authored contributions carefully selected from the latest developments in research. A unique blend of theory and practice, the book's concepts are based on exhaustive field research conducted over the past decade from the world's leading seismologists and geophysicists. - Edited by a geophysicist with nearly 20 years of experience in research, consulting, and geoscience software development - Nearly 100 figures, photographs, and examples aid in the understanding of fundamental concepts and techniques - Presents the latest research in seismic wave characteristics and analysis, the fundamentals of signal processing, wave data acquisition and inversion, and the latest developments in horizontal-to-vertical spectral ratio (HVSR) - Each chapter features a real-world case study—13 in all—to bring the book's key principles to life

Download or read book Ocean Wave Group Analysis written by Dean Gordon Sedivy and published by . This book was released on 1978 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

This book was released on 1961 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the general problem of recording and analyses of wave, submarine, and fluid motion data obtained from the USS Redfin while hovering at keel depths (near 100 feet) at different relative headings. In particular, the problem of recording surface wave heights with the Sonic Surface Scanner is discussed. Power spectral estimates obtained by both analog and digital methods are presented. Composite graphs of power spectra of data are presented, and mean values of the motion are given in tabulated form.
