Available in PDF, EPUB and Kindle. Book excerpt: This report presents behavioral responses of dolphins and white whales exposed to 1-s tones. The U.S. Office of Naval Research (ONR) and Chief of Naval Operations (CNO) (N45) have sponsored research programs to investigate the auditory effects of high intensity sounds on marine mammals. In addition to auditory effects, these studies reported behavioral reactions as the subjects were exposed to sounds of increasing intensity. The most common reactions were attempts by the subjects to avoid the site of previous noise exposures, or attempts to avoid an exposure in-progress. Schlundt et al. ̂gave a brief summary of the more significant behavioral changes they observed in dolphins and white whales exposed to intense pure tones. This report presents a more detailed summary of behavioral responses of dolphins and white whales exposed to 1-s tones. (̂Schlundt, C.E., Finneran, J.J., Carder, D.A., and Ridgway, S.H. (2000).

This book was released on 2012-01-26 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second International Conference on the Effects of Noise on Aquatic Life will take place in Ireland August 15-20, 2010. The main emphasis of the conference will be on defining the current state of knowledge. However, we will also assess progress in the three years since the First conference. The Second conference will place strong emphasis on recent research results, the sharing of ideas, discussion of experimental approaches, and analysis of regulatory issues.

Download or read book Marine Mammal Populations and Ocean Noise written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 143 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.

This book was released on 2017-06-04 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.

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.
