Download or read book Marine Animal Sound Database Twelve Years of Tracking 52 Hz Whale Calls from a Unique Source in the North Pacific written by and published by . This book was released on 2004 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term monitoring of underwater sounds using U.S. Navy SOSUS and other hydrophone arrays allowed us to follow the seasonal distribution of underwater calls produced by blue, fin and humpback whales across the North Pacific. These new data from this current study have been added to data of previous 7 years' deep-water monitoring, enabling us to document year-to-year variations in marine mammal calling. These data have also been added to the marine mammal sound archive at the Woods Hole Oceanographic Institution. Tracking of individual whales has been accomplished using the Navy's deep-water monitoring system as evidenced by the tracking of a unique 52-Hz call, with his current study cumulating a 12 year track The large WHOI sound database provided comparisons and analysis of these sounds. The year-round monitoring of blue whales has uncovered at least two distinct call types which occur in very specific regions in the North Pacific. These data collected across a broad area without the restriction of weather or time of day are invaluable to researchers interested in population trends of marine animals.

Download or read book Ethology and Behavioral Ecology of Mysticetes written by Christopher W. Clark and published by Springer Nature. This book was released on 2022-07-02 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, an international team of leading marine mammal scientists, with a remarkably diverse set of backgrounds and areas of expertise, lead you through a synthesis of current knowledge on baleen whales. Baleen whales are the largest animals ever to have lived on this planet. They also have the lowest and most intense voices on Earth, most likely evolved to take advantage of ocean acoustic transmission conditions so as to be detectable across ocean basins. Some baleen whales can live to be 150-200 years old. They migrate many thousands of kilometers between feeding and breeding areas. They produce songs and calls that serve as behavioral foundations for establishing, maintaining and expanding their cultural identities. To conclude that we know the behavioral limits of these large brained, long-lived animals would be naïve. As baleen whale scientists, we are still beginning to comprehend the enormous complexities and natural histories of these remarkable animals. Today, the fact that whales sing is known throughout much of the world. This awareness started 50 years ago with the publication and popularization of a collection of humpback song recordings that motivated research into baleen whale behavioral ethology. In this book’s chapters, a reader’s experiences will stretch from learning about baleen whale laryngeal anatomy associated with their different voices to learning about the vast ocean areas over which their voices can be heard and the emerging complexities of their culturally defined societies. These are accompanied by chapters on the fundamental ethological contexts of socializing, migrating, and foraging. Two common themes permeate the book. One theme highlights the phenomenal increase in scientific knowledge achieved through technological advancements. The other theme recognizes the impacts of human-made activities on ocean acoustic environments and the resultant influences on the health and survival of individual whales and their populations. Although the book is intentionally ambitious in its scope, as scientists, we fully recognize that baleen whale science is still in its infancy. Many profound revelations await discovery by cohorts of young, multi-talented explorers, some of whom are stretching their wings in this volume and some of whom are reading these scientific stories for the first time.

Book excerpt: A captivating exploration of how underwater animals tap into sound to survive, and a clarion call for humans to address the ways we invade these critical soundscapes—from an award-winning science writer “Sing Like Fish is that rare book that makes you see the world differently.”—Mark Kurlansky, New York Times bestselling author of Salt and Cod For centuries, humans ignored sound in the “silent world” of the ocean, assuming that what we couldn’t perceive, didn’t exist. But we couldn’t have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with the temperature and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems. In Sing Like Fish, award-winning science journalist Amorina Kingdon synthesizes historical discoveries with the latest scientific research in a clear and compelling portrait of this sonic undersea world. From plainfin midshipman fish, whose swim-bladder drumming is loud enough to keep houseboat-dwellers awake, to the syntax of whalesong; from the deafening crackle of snapping shrimp, to the seismic resonance of underwater earthquakes and volcanoes; sound plays a vital role in feeding, mating, parenting, navigating, and warning—even in animals that we never suspected of acoustic ability. Meanwhile, we jump in our motorboats and cruise ships, oblivious to the impact below us. Our lifestyle is fueled by oil in growling tankers and furnished by goods that travel in massive container ships. Our seas echo with human-made sound, but we are just learning of the repercussions of anthropogenic noise on the marine world’s delicate acoustic ecosystems—masking mating calls, chasing animals from their food, and even wounding creatures, from plankton to lobsters. With intimate and artful prose, Sing Like Fish tells a uniquely complete story of ocean animals’ submerged sounds, envisions a quieter future, and offers a profound new understanding of the world below the surface.

The program of monitoring the calling whales across the North Pacific using U.S. Navy SOSUS and other systems has continued to be productive, with regular measures of the seasonal distribution of the different whale species. The organization of the digital acoustic data was successfully completed. Both components of this program have provided important new information about the acoustic behavior of these calling marine species.
Download or read book Numbers of Calling Whales in the North Pacific written by William A. Watkins and published by . This book was released on 2001 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since November 1995, the U.S. Navy's Sound Surveillance System (SOSUS) and other hydrophone arrays were used to regularly sample the occurrence of whale sounds in four regions bordering the continental margins across the North Pacific. The numbers of whales heard calling varied with season and location for each species, blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), and humpback whales (Megaptera novaeangliae). For blue whales, calling during the fall season averaged 5 whales per event, winter averaged 1.5 whales per event, spring averaged 1 whale, and summer averaged 1.5 whales. For fin whales the numbers of whales heard ('F' calls from individuals) during winter averaged 3 whales per event, spring and fall calling averaged 1.5 whales, and summer averaged 1 whale. The 'J' calling events, regardless of season, were judged to be from at least 6 fin whales. Humpback singing typically was from 3 whales. These number demonstrated seasonal variations in calling whales for each region.

Available in PDF, EPUB and Kindle. Book excerpt: For the 119 species of marine mammals, as well as for some other aquatic animals, sound is the primary means of learning about the environment and of communicating, navigating, and foraging. The possibility that human-generated noise could harm marine mammals or significantly interfere with their normal activities is an issue of increasing concern. Noise and its potential impacts have been regulated since the passage of the Marine Mammal Protection Act of 1972. Public awareness of the issue escalated in 1990s when researchers began using high-intensity sound to measure ocean climate changes. More recently, the stranding of beaked whales in proximity to Navy sonar use has again put the issue in the spotlight. Ocean Noise and Marine Mammals reviews sources of noise in the ocean environment, what is known of the responses of marine mammals to acoustic disturbance, and what models exist for describing ocean noise and marine mammal responses. Recommendations are made for future data gathering efforts, studies of marine mammal behavior and physiology, and modeling efforts necessary to determine what the long- and short-term impacts of ocean noise on marine mammals.
Download or read book Whale Call Data for the North Pacific written by and published by . This book was released on 2000 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calls of blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), and humpback whales (Megaptera novaeangliae) were identified in the data from U.S. Navy Sound Surveilance System (SOSUS) and other hydrophone arrays. These data on calling whales from November 1995 through July 1999 have been listed here for four offshore, deep-water Regions along continental margins of the North and Northeast Pacific. The occurrence of calling whales was monitored during two-day periods each week. Call data recorded from each array identified species, call occurrence, variation, received beam, and relative numbers of calling whales. This allowed assessment of seasonal distribution of calls for the different species, and provided locations for sources received at multiple arrays. Blue whale tonal sounds were distributed widely, received most in the NW Region, with a peak in occurrence in the fall. Fin whale "20-Hz" repetitive pulse sequences were received from whales grouped in local areas in all Regions, with a peak in occurrence in midwinter. Humpback songs were received from December through May particularly in the SE Region. The offshore listening systems allowed basin-wide monitoring of the seasonal distribution of these callng whales.

Download or read book Marine Mammals and Low Frequency Sound written by National Research Council and published by National Academies Press. This book was released on 2000-06-11 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound has become a major tool for studying the ocean. Although the ocean is relatively opaque to light, it is relatively transparent to sound. Sound having frequencies below 1,000 Hertz (Hz) is often defined as low-frequency sound. The speed of sound is proportional to the temperature of the water through which it passes. Therefore, sound speed can be used to infer the average temperature of the water volume through which sound waves have passed. The relationship between water temperature and the speed of sound is the basis for the Acoustic Thermometry of Ocean Climate (ATOC) experiment. The ATOC experiment is designed to monitor the travel time of sound between sources off the coasts of Hawaii and California and several receivers around the Pacific Ocean in order to detect trends in ocean temperature and for other research and monitoring purposes. Some whales, seals, and fish use low-frequency sound to communicate and to sense their environments. For example, baleen whales and some toothed whales are known to use and respond to low-frequency sound emitted by other individuals of their species. Sharks are not known to produce low-frequency sound but are attracted to pulsed low-frequency sounds. Therefore, it is possible that human-generated low-frequency sound could interfere with the natural behavior of whales, sharks, and some other marine animals. Marine Mammals and Low-Frequency Sound is an updated review of the National Research Council 1994 report Low-Frequency Sound and Marine Mammals: Current Knowledge and Research Needs, based on data obtained from the MMRP and results of any other relevant research, including ONR's research program in low-frequency sound and marine mammals. This report compares new data with the research needs specified in the 1994 NRC report, focusing on the strengths and weaknesses of the data for answering important outstanding questions about marine mammal responses to low-frequency sound and identifies areas where gaps in our knowledge continue to exist.
Download or read book Marine Mammals and Noise written by W. John Richardson and published by Academic Press. This book was released on 2013-10-22 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.
Download or read book Echolocation in Bats and Dolphins written by Jeanette A. Thomas and published by University of Chicago Press. This book was released on 2004 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research. Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book.

This book was released on 2005-01-24 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention has been drawn to the subject of how ocean noise affects marine mammals by a series of marine mammal strandings, lawsuits, and legislative hearings, and most recently, the report from the U.S. Commission on Ocean Policy. One way to assess the impact of ocean noise is to consider whether it causes changes in animal behavior that are "biologically significant," that is, those that affect an animal's ability to grow, survive, and reproduce. This report offers a conceptual model designed to clarify which marine mammal behaviors are biologically significant for conservation purposes. The report is intended to help scientists and policymakers interpret provisions of the federal Marine Mammal Protection Act.
