Available in PDF, EPUB and Kindle. Book excerpt: A survey was made of the biological sound present in a set of tape recordings obtained from a hydrophone at 60 fathoms and another at 450 fathoms, over an 8-day period. A variety of types of biological sound were distinguished and analyzed. They were shown to have significant influence on the ambient noise level. (Author).

Book excerpt: This title brings to light the discoveries and insights into the lives of many marine species made possible over the last decade by passive acoustic recorders (PAR). Pop-ups, ARF, HARP, EAR, Bprobe, C-POD Atag, and Dtag are the acronyms of some of the many PARs that have changed our understanding of how marine animals live and strive in the ocean. Various types of PARs are used by different investigators in different areas of the world. These recorders have accumulated copious amounts of very important data, unveiling previously unknown information about large marine animals. Temporal, seasonal and spatial distribution patterns have been uncovered for many marine species. There have been many discoveries, new understandings and insights into how these animals live in and utilize the ocean and the importance of acoustics in their lives. Listening Within the Ocean summarizes these important discoveries, providing both a valuable resource for researchers and enjoyable reading for non-professionals interested in marine life.

Download or read book Ambient Noise in the Sea written by Robert J. Urick and published by . This book was released on 1986 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ambient noise may be loosely said to be unwanted sound emanating from the sea itself. Its constituents typically come from a variety of somewhat diffusely combined sources: pressure changes and hydrostatic effects of tides and waves, oceanic turbulence, seismic disturbances, distant ship traffic, wind, rainfall, collapse of bubbles created by wave action, thermal agitation, marine animals and biological activity, breaking ice, and man-made noise such as distant oil rigs. Depending on locations in the ocean space, the times of day, season and year, and the happenstance of events and nature, the aforecited sources may or may not be contribute to the totality of ambient noise at any given time and place; and it may or may not exist as broad or narrow bands of energy in different regions of the frequency spectrum. More exactly defined, ambient noise is that part of the total noise background observed by an omnidirectional hydrophone in the sea which is: (1) not due to the hydrophone system's self-noise such as the noise of current flow around the measurement hydrophone and all forms of electrical noise; ambient noise is independent of the means used to observe it; and (2) not due to other identifiable localized sources of noise. Ambient noise is what is "left over" after all identifiable noise sources are accounted for. Ambient noise is an especially important consideration in detecting and identifying targets - be the targets submarines, underwater vehicles, floating mines, or fish-- in relatively quiet ocean environments and situations. In the case of active sonar, ambient noise typically becomes the dominant background against which the sonar receiver is trying to detect, and possibly identify, targets in the ocean space (not addressing search of the ocean floor) when it is greater than self noise and after the relatively loud reverberation noise created by the active sonar pings has died down in the sonar cycle. In the case of passive sonar, after taking into account self noise and possible extraneous noise from identifiable sources, ambient noise is the background against which the sonar receiver seeks to detect and identify targets. This book, AMBIENT NOISE IN THE SEA by Robert Urick, summarizes the main features of the ambient noise and gives the reader an easy to read, understandable entry in to its unclassified literature. This book is a must for engineers in the fields of active and passive sonars, underwater sensor and weapons systems, and underwater signal processing.

Download or read book The Effects of Noise on Aquatic Life II written by Arthur N. Popper and published by Springer. This book was released on 2015-11-26 with total page 1292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The meeting of Aquatic Noise 2013 will introduce participants to the most recent research data, regulatory issues and thinking about effects of man-made noise and will foster critical cross-disciplinary discussion between the participants. Emphasis will be on the cross-fertilization of ideas and findings across species and noise sources. As with its predecessor, The Effects of Noise on Aquatic Life: 3rd International Conference will encourage discussion of the impact of underwater sound, its regulation and mitigation of its effects. With over 100 contributions from leading researchers, a wide range of sources of underwater sound will be considered.
