The Handbook of Sidescan Sonar


Book Description

Sidescan sonar is proving to be the preeminent technique for researchers and professionals seeking knowledge about the structure and behavior of the seafloor, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. This book covers the fundamentals of sidescan sonar, incorporates new understanding of marine structures, and explains how to interpret sidescan sonar imagery and bathymetry.

Commercial Diver Training Manual, 7th Edition


Book Description

“The 7th Edition of the Commercial Diver Training Manual continues to fill the gap between learning through field experience and learning through entry-level commercial diver training. Our commercial diving students and graduates have been well served since 2016 by the author’s meticulous and thorough approach to making vast field experiences and safety come alive in the 6 th Edition, and once again in this revised 7th edition. It continues to be a leading textbook in our training, due to its technical accuracy, current content, photos, and illustrations. Safety and efficiency are pinnacle traits that any successful working diver must learn in their training and constantly apply in the field. Safety is not a simply a rule book, it is a state of mind. Hal Lomax’s approach to this and sharing his knowledge with all levels of divers has made our industry safer and advanced it entirely. At the very core of commercial diver training are two essential objectives: Going up and down in the water column safely and performing useful and effective work underwater. This textbook continues to provide both objectives into a current and well written resource for the entire industry. It remains a must for anyone’s library involved in commercial diving.” Don Barthelmess, Professor Emeritus, Santa Barbara City College Marine Diving Technology Department




Commercial Diver Training Manual, 6th Edition


Book Description

Updates in the 6th Edition - Comprehensive rewrite can be used as stand-alone reference - Extensive index - Easy-to-read formatting - Color photos/tables/figures added - Colorful book cover ABOUT THE BOOK The 6th Edition of the Commercial Diver Training Manual represents an almost total rewrite. Where previous editions were designed to be utilized in conjunction either with the NOAA Diving Manual or the U.S. Navy Diving Manual, the 6th Edition has been written as a stand-alone work that covers history, physics, physiology, diving medicine, and first aid in addition to those chapters devoted to diving technique, diving equipment, and working underwater. This manual is presented with the understanding that fully qualified instructors experienced in underwater work will provide any further explanation required by the reader. At the same time, the intent was to provide a manual to enhance both the theoretical and the practical training of the diver, with a view to providing graduates that are more knowledgeable and well informed in their chosen trade, performing their assigned tasks in a safe and productive manner. To that end, this manual strives to present the following: - Diving physics in a clear, concise manner - The latest theory and procedure in physiology and diving medicine - The latest in practice and procedure both inland and offshore - The most commonly used diving and support equipment accepted for use in today’s industry While it is understood it would require several volumes to address every conceivable task performed on every type of underwater project employing commercial divers, this manual endeavors to cover the most commonly performed tasks and the most common underwater operations. By presenting these more common projects and tasks in detail, it is hoped the reader will be better informed and better prepared for a career underwater. In addition, by further illustrating both technique and safety concerns with case studies and personal accounts from the author’s career, the manual shows the reader these are more than just words being presented: suggestions help the reader become more proficient and safety guidelines keep the reader from injury or death.

Sonar Systems


Book Description

The book is an edited collection of research articles covering the current state of sonar systems, the signal processing methods and their applications prepared by experts in the field. The first section is dedicated to the theory and applications of innovative synthetic aperture, interferometric, multistatic sonars and modeling and simulation. Special section in the book is dedicated to sonar signal processing methods covering: passive sonar array beamforming, direction of arrival estimation, signal detection and classification using DEMON and LOFAR principles, adaptive matched field signal processing. The image processing techniques include: image denoising, detection and classification of artificial mine like objects and application of hidden Markov model and artificial neural networks for signal classification. The biology applications include the analysis of biosonar capabilities and underwater sound influence on human hearing. The marine science applications include fish species target strength modeling, identification and discrimination from bottom scattering and pelagic biomass neural network estimation methods. Marine geology has place in the book with geomorphological parameters estimation from side scan sonar images. The book will be interesting not only for specialists in the area but also for readers as a guide in sonar systems principles of operation, signal processing methods and marine applications.
