Book excerpt: An experiment was conducted to provide data to compare with predicted path characteristics for frequencies in the 3 to 30 MHz oceanic telemetry band. Data obtained was for use in designing telemetry equipment for buoys at sea and for command receiving stations on shore. The receiving site was located in Hawaii; while the simulated buy-at-sea site was San Diego, California. (Author).

Download or read book Measuring Ocean Currents written by Antony Joseph and published by Newnes. This book was released on 2013-08-12 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. - Coverage of measurement, mapping and profiling techniques - Descriptions of technologies for remote measurement of ocean currents and their signatures - Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change

Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of Office of Naval Research support of oceanographic investigations is to gain the understanding of the ocean environment required by the Navy to most effectively perform its mission of national defense. ONR-supported oceanography not only contributes to the national defense but inevitably makes significant contributions to the general oceanographic knowledge and to the attainment of national marine science program goals. The document contains abstracts of individual research projects on the ONR Ocean Science Program.

This book was released on 2013-11-21 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: [B&W Edition] In order to examine the practices used by underwater sensor networks for successful off-shore deep sea deployments this book analyzes the underwater channel acoustic propagation model and also looks briefly at the characteristics of the underwater transducers along with the unique effect that they pose upon sonar based communication systems. The book then goes on to exploring the state of the art in underwater sensor network design paradigms followed by an analysis of areas that warrant research. A discussion on simulating such networks and an analysis of the characteristics of the underwater acoustic channel is also carried out.

Download or read book Energy Efficient Underwater Wireless Communications and Networking written by Goyal, Nitin and published by IGI Global. This book was released on 2020-09-04 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater wireless sensor networks (UWSN) are envisioned as an aquatic medium for a variety of applications including oceanographic data collection, disaster management or prevention, assisted navigation, attack protection, and pollution monitoring. Similar to terrestrial wireless sensor networks (WSN), UWSNs consist of sensor nodes that collect the information and pass it to a base station; however, researchers have to face many challenges in executing the network in an aquatic medium. Energy-Efficient Underwater Wireless Communications and Networking is a crucial reference source that covers existing and future possibilities of the area as well as the current challenges presented in the implementation of underwater sensor networks. While highlighting topics such as digital signal processing, underwater localization, and acoustic channel modeling, this publication is ideally designed for machine learning experts, IT specialists, government agencies, oceanic engineers, communication experts, researchers, academicians, students, and environmental agencies concerned with optimized data flow in communication network, securing assets, and mitigating security attacks.
