This book was released on 1999 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: A four-day experiment was conducted to study the feasibility of locating, tracking, and counting blue whales acoustically in the Monterey Bay National Marine Sanctuary (MBNMS) at long ranges using the shore-based NPS Ocean Acoustic Observatory (OAO) hydrophone array. In concert with the shore-based acoustic monitoring, an aircraft was assigned to locate whales and a research vessel was manned with observers and instrumented with a towed hydrophone array to determine whale locations and characterize their vocalizations in the near-field. Two transiting blue whales were observed and their vocalizations were recorded by the towed array in close proximity. In this thesis research, these towed array data were deverberated using modeled-based matched signal processing and least-squares fitting.

Download or read book Characterization of Blue Whale Calls from the Northeast Pacific and Development of a Matched Filter to Locate Blue Whales on the U S Navy SOSUS SOund SUrveillance System Arrays written by Kathleen Mary Stafford and published by . This book was released on 1995 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blue whales (Balaenoptera musculus) are the largest of the baleen whales. Blue whale calls were recorded off the coast of California in fall, 1993 and measured for frequency and time characteristics. On average, blue whale calls lasted 16 s, swept down from 18.9 to 17.3 Hz and were repeated every 38 s. These results are similar to blue whale calls recorded elsewhere in that they possess a frequency downsweep component which lasts from 16-18 s. Ambient noise levels in the ocean due to sources such as wind, waves or shipping can make it difficult to detect blue whale calls in raw hydrophone data. The characteristics of the blue whale calls recorded in the field were sufficiently similar to design a matched filter (kernel) to automatically detect calls obscured by ambient noise. This filter worked well at identifying blue whale calls when applied to the data from which it was derived and on data from the U.S. Navy's SOSUS (SOund SUrveillance System) array. The U.S. Navy has been monitoring low-frequency sounds in the northeast Pacific using bottom-mounted hydrophone arrays since the mid- 1950's. The use of this system was extended to the study of low-frequency whale calls. By applying the matched filter developed from field data to each of three hydrophone arrays and using location algorithms developed for seismic work, it was possible to pick the same call on each array and determine its location by examining the arrival time differences at each hydrophone and comparing this to a predefined location. To confirm the validity of these locations, a ground-truthing experiment was conducted whereby a Navy P-3 aircraft was given locations determined with the matched filter to try to visually and/or acoustically locate blue whales off the Oregon coast. Other locations were determined for 10 days in July and August, 1994.

Available in PDF, EPUB and Kindle. Book excerpt: This book evolved through the efforts of several organizations and the dedication of many individuals. In 1987, we received arequest to propose a workshop topic for the Fifth International Theriological Congress (ITC) to be held in August 1989 in Rome, Italy. After looking up the meaning of the word "theriological" in the dictionary and discovering that it pertains to mammalian behavior, we decided a symposium on sensory abilities of whales and dOlphins would be an interesting topic. The ITC convenes only every five years and has the distinction of being very weIl attended by scientists from around the world. We thought that hosting a workshop in conjunction with the ITC would attract a variety of international scientists that rarely have the opportunity to interact. Fortunately for all involved, our prediction was correct. The first two days of the workshop, 23-24 August 1989, were held in conjunction with ITC and the nearly 1,000 attending scientists were able to view our posters and listen to lectures. The third day was limited to only ab out 65 invited scientists who were divided into topical working groups chaired by a rapporteur.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Since technological progress is characterized by the dual effects, positive and negative, it is precisely by sustaining the balance between such binaries that ecologically responsible resource management is restored as a solution for excessive human impact on the environment. Sound and music became relevant from the perspective of management, within the meaning of controlling their negative effects on human beings and their environment as well as utilizing them for meeting human needs. This book integrates the fields of technology, humanities, and social sciences and defines the challenges of noise control from the perspective of acoustic ecology. It discusses the concept of acoustic ecology applied to evoke sound and music management and design solutions for well-being. It will be equally useful for students of electrical engineering, music, and economics; equally challenging to those with a particular prior knowledge and practice; and as much as comprehensive and stimulative for those who are barely embarking upon a new adventure.
