Book Description
Information from field tests, literature, and published data was gathered to establish the operating principles, capabilities and limitations, environmental restrictions, and availability of acoustic systems from the standpoint of conditions in the Lower Mississippi Valley. The acoustic systems are commonly classified according to the method by which the sound energy is produced, such as boomers, sparkers, and gas guns. Different degrees of resolution and penetration are achieved, largely because of differences in the frequency spectrum of the generated energy. However, because of inherent limitations, it is impossible to achieve both high resolution and deep penetration with any acoustic system. Either transducers or hydrophones of various designs are used to detect signals reflecting from subbottom horizons. Graphic recorders of various types are used with most acoustic profiling systems; however, magnetic-tape recording and signal processing is being accomplished with increasing frequency. Proper interpretation of acoustic subbottom profiles required an awareness of and possible corrections for scale variations caused by several factors, recognition of multiple reflections, an understanding of why reflections occur, and recognition of characteristic signatures. System selection for a particular survey requires a consideration of operational factors such as size and weight of equipment as well as environmental factors such a(Author).

Book Description
This book focuses on the survey technology, post-processing technology, mapping technology and scientific application of the submarine topography and geomorphology in detail. High-resolution submarine geomorphology is a frontier branch of marine geology and marine surveying and mapping, which provides a direct basis to study the seabed surface, to understand the tectonic movement and submarine evolution. In the past two decades, high-resolution submarine geomorphology with high-precision multi-beam echo sounding, side-scan sonar and sub-bottom profiler as the major techniques, is developing very quickly and is one of the frontiers of international marine science and technology. These high techniques promote the traditional submarine geomorphology to high-resolution and quantitative research. At present, high-resolution submarine geomorphology is widely used in the delimitation of the continental shelf, the international seabed resources survey, marine engineering and marine military applications. In order to facilitate readers to understand how to acquire and apply scientific research based on submarine topographic data, it highlights the combination of theory, technology and scientific application. This book is useful as a reference for professional and technical personnel in related fields and also as a textbook for both graduate and undergraduate students as well.

Book Description
This book on the current state of knowledge of submarine geomorphology aims to achieve the goals of the Submarine Geomorphology working group, set up in 2013, by establishing submarine geomorphology as a field of research, disseminating its concepts and techniques among earth scientists and professionals, and encouraging students to develop their skills and knowledge in this field. Editors have invited 30 experts from around the world to contribute chapters to this book, which is divided into 4 sections – (i) Introduction & history, (ii) Data & methods, (ii) Submarine landforms & processes and (iv) Conclusions & future directions. Each chapter provides a review of a topic, establishes the state-of-the-art, identifies the key research questions that need to be addressed, and delineates a strategy on how to achieve this. Submarine geomorphology is a priority for many research institutions, government authorities and industries globally. The book is useful for undergraduate and graduate students, and professionals with limited training in this field.

Book Description
This book examines the process and patterns of glacier-influenced sedimentation on high-latitude continental margins and the geophysical and geological signatures of the resulting sediments and landforms. It contains a range of papers concerning modern and glacially-influenced sedimentation in high-latitude areas from both hemispheres, many of which discuss the relationship between glacier dynamics and the sediments and landforms preserved in the glacimarine environment.
